- the inner surfaces of the air-conditioning air duct A30 and the air-conditioning air duct B31 are substrate boards, beams, joists, etc., and fine dust and the like originally adhered to them are mixed with the room or space by the air-conditioned air passing through.
- the material may also serve as an airtight sheet or may be attached alone.
- the conditioned air even if the conditioned air is not attached, if the conditioned air is allowed to flow continuously for a while, it will be cleaned by the plurality of filter units and the air purifier 90, and will be discharged to the outside by the exhaust fan of the heat exchange air unit 60 and the ceiling-mounted ventilation fan 81. After that, the cleaned conditioned air circulates in the building 2.
- the air-conditioned air that has passed through the air-conditioned air passage B31 is blown out from the air outlet 42 of the entrance 13, and the motors of the air blowers 45 and 46 that can adjust the air volume to 100 m 3 /h to 200 m 3 /h are operated.

- the air outlets 40 and 41 are provided with blower fans because they are farther from the connection part 35 of the air conditioning air passage B31 than the air outlet 42.
- the air volume from the air outlets 40 and 41 may be less than the designed air volume, such as when the opening area of the air outlets 50 and 51 is small, and the temperature between the rooms and spaces may become uneven. This is because there is a possibility that the temperature in the room or space may become uneven.

Airflow required for air conditioning is at least 8m 3 /h or more per 2.5m 3 room, ideally 20m 3 /h or more. . Since the blower unit 17 rotates a sirocco fan (not shown) with a highly efficient DC motor (not shown), the rotation speed of the sirocco fan (not shown) is controlled by the control unit 140 and the motor control unit 140 depending on the air conditioning load and the like. It is controlled by the unit 141 .
- the number of air blowing units 17 is one for each air outlet, but if the air blowing unit 17 has a margin for the required air blow amount described above, the number of air outlets may be increased depending on the shape of the room or space. Although it is possible to do so, there is a possibility that moisture, dust, bacteria, etc. will accumulate and accumulate in the air-conditioning air duct along the way due to changes in air volume distribution due to resistance in the air-conditioning air duct and reduction in wind speed. Also, maintenance such as cleaning is difficult, so in principle, it is desirable to have a ratio of 1:1. If multiple outlets are to be provided, a blower fan should be installed at the outlet, or the inside of the branch may be cleaned or replaced later. It is necessary to provide an inspection door nearby so that

- the average temperature of the air in the air conditioning duct is Assuming the temperature to be 25°C, the average temperature of the room/space of 17°C is assumed to be the set temperature of 20°C.
- the air conditioning unit 20 is set so that the average temperature of the air in the air conditioning duct is 17°C to 27°C within 10K during heating (the average temperature in the air conditioning duct at this point is 25°C).
- the temperature is determined to be 22° C.
- the air blowing volume of the air blowing unit 17 is determined to be 200 m 3 /h
- each signal is sent through the signal line 151 to the control unit 130 of the air conditioning unit 20, and through the signal line 153, a plurality of air blowing A signal is sent to the control unit 140 of the unit 17 .
- the control unit 130 of the air conditioning unit 20 receives the signal of the operation mode “heating” and the set temperature “22° C.” For example, the rotation speed of the fan 90 is 900 r/min, the angle of the louver 94 is 60 degrees downward from the horizontal, the compressor is operated at a medium frequency of 52 Hz, and the rotation speed of the outdoor fan is 900 r/min. instruct.
- the controllers 140 of the plurality of blowers 17 that have received the signal of the air blow volume of "200 m 3 /h" instruct the respective motor controllers 141 to set the rotation speed of each motor to, for example, 1200 r/min.
- the control unit 114 keeps the average temperature of the room and space at the set temperature. determines the set temperature of the air conditioning unit 20 and the air blowing volume of the air blowing unit 17 so that the average temperature of the air in the air conditioning air passage is within 10 K, and controls the air conditioning unit 20 through the signal line 151. A signal is sent to the unit 130 , and a signal is sent to the control unit 140 of the plurality of blower units 17 through the signal line 153 .

- control units 140 of the plurality of air blowing units 17 that have received the air blow volume signal instruct the respective motor control units 141 of the rotation speeds of the respective motors. The above is repeated until the air conditioning unit controller 110 stops.
- the air blower 17 is controlled in rotation speed during operation, but does not stop, and continues to rotate the sirocco fan and blow air to the air conditioning air passage. This is because it is effective in keeping the air in the air-conditioning ducts moving, sweeping out surface dust and the like from the air outlet, evaporating moisture, and making the temperature and humidity in the building 2 uniform, including inside and outside the air-conditioning ducts. be. Basically, it is desirable that the operation by the air-conditioning unit controller 110 should be continuous 24 hours a day, 365 days a year, except for maintenance stoppages and long-term absences.
- the blower unit 17 Since the blower unit 17 is rotated by a highly efficient DC motor (not shown), it is originally energy saving, and the power consumption is further reduced in proportion to the rotation speed, but the compressor of the air conditioning outdoor unit 18 is the consumption of this system. It accounts for a large proportion of electricity. Therefore, even in continuous operation, if the air conditioning load is not particularly large due to the outdoor temperature or solar radiation, the compressor operates at a low frequency or stops during stable operation, so the air blower 17 continues to operate. Although the power consumption of the system is very low, it is very effective in preventing the adhesion and deposition of dust, mold, and moisture in the air-conditioning air duct.
- the average temperature of the room and space should be set as the set temperature
- the air in the air-conditioning ventilation path should be within 5K during cooling and within 10K during heating, relative to the average temperature of the air around the air-conditioning ventilation path. If it is not possible to achieve both the average temperature of the , when the air conditioning load is large, hidden operations provided in the air conditioning unit controller 110 (for example, the set temperature is set to the minimum or maximum temperature at the start of operation, etc.) , keeping the average temperature of the air in the air conditioning duct within 5 K during cooling and within 10 K during heating.

Description
本発明は、建物内全体を空調換気する空調換気システムに関する。
The present invention relates to an air-conditioning and ventilation system that air-conditions and ventilates the entire building.
建物は省エネで快適な暮らし実現のため、ますます高気密化、高断熱化が進んでいる。そのような住宅、非住宅では、建物内に、空調機から空調換気空気を、部屋や空間に送風するため、ダクトを建物内に引き回して、各部屋等を空調換気するダクト式空調換気システムが多く採用されているが、ダクトの代わりに、床下空間、天井裏空間、階間空間等を通風路として用い、建物内をくまなく空調換気する空調換気システムが一部で採用されている。
このような空調換気システムでは、ダクトを引き回す必要がなく、ダクト材料費と施工費のコストダウンとなり、ダクトの代わりに、床下空間等を通風路として使用できるので、通常建物に存在するスペースを利用するため、ダクトを引き回すスペースが不要で、合理的であるが、空調や換気した空気を床下空間等の通風路により、部屋等に送風しているため、長期間の使用により、通風路の内部に、建物内外の埃、ハウスダスト、人やペットのフケ、ダニやダニの糞、死骸、VOC、カビなどのアレルゲンなどが堆積する。
また、一般的な空調機、例えば、冷房能力4kW程度の空調機では、空調機からの吹出空気温度が吸込空気温度に対して冷房時で5K~15K程度低く、暖房時で10K~30K程度高く、風量が約400~800m3/hの空調空気が通風路を通過すると、通風路内での温度勾配が大きく、温度差により、通風路内外で結露しやすく、通風路に複数の吹出口がある場合、空調機に近い吹出口では能力が多いが、遠くの吹出口では能力が少ないなど、吹出口の位置により建物内の温度分布が不均一となる。
特に、そういった通風路の内部は、「5~40℃前後の温度」、「60%以上の高い湿度による付着した水分」、「付着した埃、汚れ等の栄養分」、というカビの繁殖条件が揃っており、通風路内外の温度差により、通風路内の堆積した埃等や通風路を構成する金属、木材、断熱材等に結露し、そこでカビやダニが繁殖しやすい。
そして、そこを空調空気が通過することにより、空調空気に埃やカビ、細菌、異臭などがのって、それを吸った人が、呼吸器系の疾患や皮膚トラブルなどアレルギーを発症するなどして、健康を害したり、臭い等により不快になるリスクがある。
さらに、通風路の断熱性が悪く、通風路の周囲が断熱空間ではない場合、通風路の外周にも結露して、結露が通風路周囲の木材等を濡らして、カビが生えたり、生活空間から見えるシミになったり、腐って強度的な被害を被ったり、結露が電線につたって、漏電するなどのリスクが発生する。
結露防止のため、通風路の内部に断熱材のグラスウールを設けると、その表面張力や毛細管現象により水分が繊維の隙間に入り込んでしまい、乾いたとしても、繊維同士がくっついてしまい、断熱機能に必要な大量の空気を溜め込むことができなくなり、断熱機能が低下するため、一度通風路内部に結露すると、ますます、結露しやすくなり、空調の効きが悪くなり、消費電力が増大する。
結露については、例えば、冷房運転で、空調機の圧縮機が運転しているサーモON時の冷たい吹き出し空気が通風路内を通過するため、通風路内部表面が冷やされ、それが例えば10℃となっている状態で、サーモOFFして、圧縮機が停止し、室内空気を吸い込むことにより、室内空気温度で、蒸発器に結露した凝縮水を含んで高湿度となった吹き出し空気が、通風路内を通過すると、その空気の温湿度が25℃、80%(露点温度21℃)の場合、通風路内部表面に結露する。
また、通風路が住宅内の断熱空間を通らず、通風路の断熱性能が低い場合、夏季、その空間の温湿度は外気温に近く、例えば外気温35℃、空間温度30℃、相対湿度50%(露点温度18.4℃)で、冷房運転により、冷たい吹出空気が通風路内を通過し、通風路外部表面温度が露点温度以下になると、通風路外部表面に結露する。
また、冬季、その空間の温度は外気温に近く、例えば外気温0℃、空間温度2℃となっている状態で、暖房運転で、圧縮機が運転しているサーモON時の暖かい吹き出し空気(温湿度50℃11%(露点温度12℃))が、通風路内を通過し、通風路内部表面温度が露点温度以下になると、通風路内部表面に結露する。さらに、サーモOFFして、圧縮機が停止し、室内空気を吸い込むことにより、室内空気温湿度が、通風路内を通過すると、その空気の温湿度が20℃60%(露点温度12℃)で、通風路内部表面温度が露点温度以下になると、通風路内部表面に結露する。冬季、過乾燥防止のため、加湿器で室内を加湿している場合は、さらに結露しやすくなる。
そのため、床下空間等の通風路の内部を定期的に清掃する必要があるが、通常、通風路は気密性が必要なため、点検口がない場合が多く、周囲の床板等をはがすなどが必要だが、どこを通風路として使用しているかの確認さえも困難である。また、点検口があったとしても、通風路内部を清掃するにも、通風路の形状、構造により、十分清掃できず、例えば、内部に梁や根太等があると、それらが邪魔して清掃は困難で、それらに埃やダニ、カビ等が付着して、除去できないこともある。
従って、通風路の清掃はできたとしても、時間、コストが大幅にかかる。さらに、通風路内部をメンテや清掃しやすいように、スペースを確保するようにすると、居住スペースが大幅に減少してしまう。
従来、各室内への空気搬送式空調は、気密性を付加したチャンバー構造の天井裏と、この天井裏と室内を連通する複数の室内側吐出口と、天井裏に連通する天井裏吹出口と室内側吸込口を有した箱状の本体と、この本体内に室内側吸込口より吸い込み天井吹出口より吹き出すように設けた送風機および送風機により形成される通風路に設けられる冷房用熱交換器と暖房用熱交換器とを備え、冷房用熱交換器と暖房用熱交換器を通風路を2分するように各風路面をほぼ同一平面上に並設した構成とし、再熱するための暖房用熱交換器に直接室内空気を吸い込み、少ない風量を流すことによって、潜熱能力を増やし、顕熱能力を減らした乾燥冷気および冷温風を天井裏へ吹き出すため、天井裏に梁がある場合や天井裏自体が狭い場合でも結露せずに確実に各室内へ空気搬送による空調ができる空気調和装置が知られている(例えば、特許文献1参照)。
また、全館空調システムにおいて、一階の居室の天井部と二階の居室の床面との階間の天井裏空間を給気経路とし、給気経路である天井裏空間内に複数の空調機が配置されており、一階の居室の天井部に複数の吹出口が設けられ、二階の居室の床面に複数の吹出口が設けられて、複数の吹出口には、それぞれ独立してON/OFF並びに回転数調節可能なブースターファンが設けられて、空調機能と換気機能を兼備し、施工が容易で、ダクトのメンテナンスが不要な全館空調システムが知られている(例えば、特許文献2参照)。
また、建物ユニット及び建物において、階段空調ユニットは、空調機器と、空調機器の吹出口として吹出部を備え、吹出部は、建物の2つの階層の間の天井懐内に開口することにより、階段空調ユニットの冷暖房機の冷暖房吹出空気と熱交換器の室外空気が、建物の階層の天井懐内に入り、1階の天井と2階の床からそれらが吹き出して空調換気するものが知られている(例えば、特許文献3参照)。
また、住宅で換気及び冷暖房を行うための送風用ダクト及び送風システムにおいて、ダクトの内面に木炭粉を含む塗装被膜を形成し、このダクトで空気の取り入れ口や吹出口と送風装置とを連結して、住宅の送風システムを構成し、木炭粉によるダクト内のカビや悪臭の発生を押え、また空気に含まれる臭いを除去できるようにして快適な住宅環境が得られるようにしたものが知られている(例えば、特許文献4参照)。 Buildings are becoming more and more airtight and highly insulated in order to realize energy-saving and comfortable living. In such residential and non-residential buildings, in order to send conditioned and ventilated air from the air conditioner to the rooms and spaces in the building, ducts are routed inside the building to air-condition and ventilate each room. Although it is widely used, some air conditioning and ventilation systems are used to air-condition and ventilate the entire building by using the underfloor space, ceiling space, inter-floor space, etc. as ventilation paths instead of ducts.
In such an air-conditioning and ventilation system, there is no need to route ducts, which reduces duct material costs and construction costs, and the space under the floor can be used as a ventilation path instead of ducts. Therefore, there is no need for space to run ducts, which is reasonable. Dust inside and outside the building, house dust, dander from people and pets, dust mites and mites feces, carcasses, VOCs, allergens such as mold, etc. accumulate.
In a general air conditioner, for example, an air conditioner with a cooling capacity of about 4 kW, the temperature of the air discharged from the air conditioner is lower than the intake air temperature by about 5 K to 15 K during cooling, and is higher by about 10 K to 30 K during heating. When conditioned air with an air volume of about 400 to 800 m 3 /h passes through the ventilation passage, the temperature gradient inside the ventilation passage is large, and due to the temperature difference, condensation easily occurs inside and outside the ventilation passage, and there are multiple outlets in the ventilation passage. In some cases, the temperature distribution in the building becomes uneven depending on the position of the air outlet, such as the air outlet close to the air conditioner has high capacity, but the air outlet far away has low capacity.
In particular, the inside of such a ventilation passage has all the conditions for mold growth, such as "temperature around 5 to 40°C", "adhered moisture due to high humidity of 60% or more", and "adhered nutrients such as dust and dirt". Due to the difference in temperature between the inside and outside of the ventilation passage, dust accumulated in the ventilation passage and dew condensation on the metal, wood, heat insulating material, etc. that make up the ventilation passage, mold and mites tend to propagate there.
As the conditioned air passes through the conditioned air, dust, mold, bacteria, and odors get on the conditioned air, and the person who breathes it develops allergies such as respiratory diseases and skin troubles. There is a risk of harming health or being uncomfortable due to odors, etc.
Furthermore, if the heat insulation of the ventilation channel is poor and the space around the ventilation channel is not insulated, condensation will also form on the outer periphery of the ventilation channel. There are risks such as stains that can be seen from outside, severe damage due to rot, and dew condensation that spreads to electric wires and causes short circuits.
If glass wool is used as a heat insulating material inside the ventilation passages to prevent condensation, water will enter the gaps between the fibers due to its surface tension and capillary action. A necessary large amount of air cannot be stored, and the heat insulating function deteriorates. Therefore, once dew condensation occurs inside the ventilation passage, the dew condensation becomes more likely, the efficiency of the air conditioning deteriorates, and the power consumption increases.
As for condensation, for example, in cooling operation, cold blown air when the compressor of the air conditioner is running and the thermostat is ON passes through the ventilation passage, so the inner surface of the ventilation passage is cooled, for example, 10 ° C. In this state, the thermostat is turned off, the compressor stops, and the indoor air is sucked in, and the blown out air, which contains condensed water condensed on the evaporator and becomes highly humid at the indoor air temperature, flows into the ventilation passage. If the temperature and humidity of the air are 25° C. and 80% (dew point temperature of 21° C.), condensation will form on the inner surface of the ventilation passage.
In addition, if the ventilation path does not pass through the heat insulating space in the house and the heat insulation performance of the ventilation path is low, the temperature and humidity of that space are close to the outside air temperature in summer. % (dew point temperature 18.4° C.), cold blown air passes through the inside of the ventilation passage due to cooling operation, and when the temperature of the outside surface of the ventilation passage falls below the dew point temperature, dew condensation occurs on the outside surface of the ventilation passage.
In winter, the temperature of the space is close to the outside air temperature, for example, the outside temperature is 0°C and the space temperature is 2°C. A temperature and humidity of 50° C. and 11% (dew point temperature of 12° C.) pass through the ventilation passage, and when the temperature of the inner surface of the ventilation passage falls below the dew point temperature, condensation forms on the inner surface of the ventilation passage. Furthermore, when the thermostat is turned off, the compressor stops, and indoor air is sucked in, the temperature and humidity of the indoor air pass through the ventilation passage, and the temperature and humidity of the air is 20°C 60% (dew point temperature 12°C). When the temperature of the inner surface of the air duct becomes lower than the dew point temperature, condensation forms on the inner surface of the air duct. In winter, when the room is humidified with a humidifier to prevent overdrying, condensation is more likely to occur.
Therefore, it is necessary to periodically clean the inside of the ventilation passages such as the underfloor space, but since the ventilation passages usually need to be airtight, there are often no inspection openings, and it is necessary to remove the surrounding floorboards. However, it is difficult to even confirm where it is being used as a ventilation channel. In addition, even if there is an inspection opening, cleaning the inside of the ventilation passage may not be possible due to the shape and structure of the ventilation passage. are difficult to remove, and dust, mites, mold, etc. adhere to them and may not be removed.
Therefore, even if the ventilation passage can be cleaned, it takes much time and cost. Furthermore, if a space is secured to facilitate maintenance and cleaning of the inside of the ventilation passage, the living space will be greatly reduced.
Conventionally, the air-conveying type air conditioning system for each room consists of a space above the ceiling with an airtight chamber structure, multiple air outlets that communicate with the space above the ceiling and the inside of the room, and air outlets that communicate with the space above the ceiling. A box-shaped main body having an indoor air inlet, a blower provided in the main body so as to draw air from the indoor air inlet and blow out from the ceiling air outlet, and a cooling heat exchanger provided in the ventilation path formed by the air blower. A heat exchanger for heating is provided, and the heat exchanger for cooling and the heat exchanger for heating are arranged side by side on almost the same plane so as to divide the ventilation path into two, and the heating is performed for reheating. Room air is directly sucked into the heat exchanger for indoor use, and the latent heat capacity is increased by flowing a small amount of air. There is known an air conditioner that can perform air conditioning by conveying air into each room without condensation even if the back itself is narrow (see, for example, Patent Document 1).
In addition, in the central air conditioning system, the space above the ceiling between the ceiling of the living room on the first floor and the floor surface of the living room on the second floor is used as an air supply route, and multiple air conditioners are installed in the space above the ceiling, which is the air supply route. A plurality of air outlets are provided on the ceiling of the living room on the first floor, and a plurality of air outlets are provided on the floor of the living room on the second floor. A whole-building air-conditioning system is known that is provided with a booster fan that can be turned off and rotated, has both air-conditioning and ventilation functions, is easy to install, and does not require duct maintenance (see, for example, Patent Document 2). .
In addition, in the building unit and the building, the staircase air conditioning unit includes an air conditioner and an air outlet as an air outlet for the air conditioner. It is known that the cooling and heating air blown out from the cooling and heating machine of the air conditioning unit and the outdoor air from the heat exchanger enter the ceiling pocket of the floor of the building and are blown out from the ceiling of the first floor and the floor of the second floor to perform air conditioning and ventilation. (See, for example, Patent Document 3).
In addition, in air ducts and air blowing systems for ventilation, air conditioning and heating in houses, a paint film containing charcoal powder is formed on the inner surface of the duct, and the duct connects the air intake and air outlet with the air blower. It is known that a house ventilation system is constructed to suppress the generation of mold and bad odors in ducts due to charcoal powder, and to provide a comfortable living environment by removing odors contained in the air. (SeePatent Document 4, for example).
このような空調換気システムでは、ダクトを引き回す必要がなく、ダクト材料費と施工費のコストダウンとなり、ダクトの代わりに、床下空間等を通風路として使用できるので、通常建物に存在するスペースを利用するため、ダクトを引き回すスペースが不要で、合理的であるが、空調や換気した空気を床下空間等の通風路により、部屋等に送風しているため、長期間の使用により、通風路の内部に、建物内外の埃、ハウスダスト、人やペットのフケ、ダニやダニの糞、死骸、VOC、カビなどのアレルゲンなどが堆積する。
また、一般的な空調機、例えば、冷房能力4kW程度の空調機では、空調機からの吹出空気温度が吸込空気温度に対して冷房時で5K~15K程度低く、暖房時で10K~30K程度高く、風量が約400~800m3/hの空調空気が通風路を通過すると、通風路内での温度勾配が大きく、温度差により、通風路内外で結露しやすく、通風路に複数の吹出口がある場合、空調機に近い吹出口では能力が多いが、遠くの吹出口では能力が少ないなど、吹出口の位置により建物内の温度分布が不均一となる。
特に、そういった通風路の内部は、「5~40℃前後の温度」、「60%以上の高い湿度による付着した水分」、「付着した埃、汚れ等の栄養分」、というカビの繁殖条件が揃っており、通風路内外の温度差により、通風路内の堆積した埃等や通風路を構成する金属、木材、断熱材等に結露し、そこでカビやダニが繁殖しやすい。
そして、そこを空調空気が通過することにより、空調空気に埃やカビ、細菌、異臭などがのって、それを吸った人が、呼吸器系の疾患や皮膚トラブルなどアレルギーを発症するなどして、健康を害したり、臭い等により不快になるリスクがある。
さらに、通風路の断熱性が悪く、通風路の周囲が断熱空間ではない場合、通風路の外周にも結露して、結露が通風路周囲の木材等を濡らして、カビが生えたり、生活空間から見えるシミになったり、腐って強度的な被害を被ったり、結露が電線につたって、漏電するなどのリスクが発生する。
結露防止のため、通風路の内部に断熱材のグラスウールを設けると、その表面張力や毛細管現象により水分が繊維の隙間に入り込んでしまい、乾いたとしても、繊維同士がくっついてしまい、断熱機能に必要な大量の空気を溜め込むことができなくなり、断熱機能が低下するため、一度通風路内部に結露すると、ますます、結露しやすくなり、空調の効きが悪くなり、消費電力が増大する。
結露については、例えば、冷房運転で、空調機の圧縮機が運転しているサーモON時の冷たい吹き出し空気が通風路内を通過するため、通風路内部表面が冷やされ、それが例えば10℃となっている状態で、サーモOFFして、圧縮機が停止し、室内空気を吸い込むことにより、室内空気温度で、蒸発器に結露した凝縮水を含んで高湿度となった吹き出し空気が、通風路内を通過すると、その空気の温湿度が25℃、80%(露点温度21℃)の場合、通風路内部表面に結露する。
また、通風路が住宅内の断熱空間を通らず、通風路の断熱性能が低い場合、夏季、その空間の温湿度は外気温に近く、例えば外気温35℃、空間温度30℃、相対湿度50%(露点温度18.4℃)で、冷房運転により、冷たい吹出空気が通風路内を通過し、通風路外部表面温度が露点温度以下になると、通風路外部表面に結露する。
また、冬季、その空間の温度は外気温に近く、例えば外気温0℃、空間温度2℃となっている状態で、暖房運転で、圧縮機が運転しているサーモON時の暖かい吹き出し空気(温湿度50℃11%(露点温度12℃))が、通風路内を通過し、通風路内部表面温度が露点温度以下になると、通風路内部表面に結露する。さらに、サーモOFFして、圧縮機が停止し、室内空気を吸い込むことにより、室内空気温湿度が、通風路内を通過すると、その空気の温湿度が20℃60%(露点温度12℃)で、通風路内部表面温度が露点温度以下になると、通風路内部表面に結露する。冬季、過乾燥防止のため、加湿器で室内を加湿している場合は、さらに結露しやすくなる。
そのため、床下空間等の通風路の内部を定期的に清掃する必要があるが、通常、通風路は気密性が必要なため、点検口がない場合が多く、周囲の床板等をはがすなどが必要だが、どこを通風路として使用しているかの確認さえも困難である。また、点検口があったとしても、通風路内部を清掃するにも、通風路の形状、構造により、十分清掃できず、例えば、内部に梁や根太等があると、それらが邪魔して清掃は困難で、それらに埃やダニ、カビ等が付着して、除去できないこともある。
従って、通風路の清掃はできたとしても、時間、コストが大幅にかかる。さらに、通風路内部をメンテや清掃しやすいように、スペースを確保するようにすると、居住スペースが大幅に減少してしまう。

また、全館空調システムにおいて、一階の居室の天井部と二階の居室の床面との階間の天井裏空間を給気経路とし、給気経路である天井裏空間内に複数の空調機が配置されており、一階の居室の天井部に複数の吹出口が設けられ、二階の居室の床面に複数の吹出口が設けられて、複数の吹出口には、それぞれ独立してON/OFF並びに回転数調節可能なブースターファンが設けられて、空調機能と換気機能を兼備し、施工が容易で、ダクトのメンテナンスが不要な全館空調システムが知られている(例えば、特許文献2参照)。
また、建物ユニット及び建物において、階段空調ユニットは、空調機器と、空調機器の吹出口として吹出部を備え、吹出部は、建物の2つの階層の間の天井懐内に開口することにより、階段空調ユニットの冷暖房機の冷暖房吹出空気と熱交換器の室外空気が、建物の階層の天井懐内に入り、1階の天井と2階の床からそれらが吹き出して空調換気するものが知られている(例えば、特許文献3参照)。
また、住宅で換気及び冷暖房を行うための送風用ダクト及び送風システムにおいて、ダクトの内面に木炭粉を含む塗装被膜を形成し、このダクトで空気の取り入れ口や吹出口と送風装置とを連結して、住宅の送風システムを構成し、木炭粉によるダクト内のカビや悪臭の発生を押え、また空気に含まれる臭いを除去できるようにして快適な住宅環境が得られるようにしたものが知られている(例えば、特許文献4参照)。 Buildings are becoming more and more airtight and highly insulated in order to realize energy-saving and comfortable living.

しかしながら、特許文献1に記載の空気搬送式空調では、天井裏以外に空調空気を流すことはできないため、例えば、建物全体の気密性、断熱性が低い場合や天井断熱の建物の場合など、建物の構造により対応ができない場合があり、対応できたとしても、顕熱能力を減らした空気で空調するため、運転の立ち上がり時や室外空気を導入した時、入浴等により空調負荷が増えた時に、顕熱能力不足で、温湿度が安定しない、もしくは、安定するのに時間がかかるという問題があった。

However, even if it can be handled, it will be air-conditioned with air with reduced sensible heat capacity, so when the air conditioning load increases due to the start of operation, outdoor air, bathing, etc. Due to the lack of sensible heat capacity, there was a problem that the temperature and humidity were not stable, or it took a long time to stabilize.
In addition, there is a possibility that dust and the like may accumulate in the chamber above the ceiling, making maintenance difficult and making it difficult to keep the inside of the building, including the inside of the ceiling, clean.
In addition, in the central air-conditioning system described inPatent Document 2, since the space above the ceiling between floors is used as an air supply path, condensation occurs and dust enters, causing dust to accumulate in the space above the ceiling between floors, causing mold. There is a problem that the environment tends to be unsanitary, such as the growth of moth, and maintenance such as cleaning is difficult.
In addition, there is also the problem that a large space is required in the attic space between floors to install the air conditioner, which narrows the living space and makes it difficult to efficiently return the return air from each living room to the air conditioner. rice field.
In addition, in the building unit and building described inPatent Document 3, the air blown from the air conditioner and the outdoor air from the heat exchanger enter directly into the ceiling cavity between stories, so dew condensation occurs in the ceiling cavity, the floor, and the ceiling. There was a problem that there was a possibility that dust and the like could accumulate.
In addition, since the flow of return air from the building is also unclear, there is also the problem that the air conditioning load and the air blowing load increase, and the power consumption of the air conditioner and air blower may also increase.

また、特許文献4に記載の送風用ダクト及び送風システムでは、ダクト内部の木炭粉を含む塗装被膜の表面上に、埃や菌等が堆積し、結露した場合、カビ等の繁殖を防止できず、ダクトや通風路の内部を塗装する必要があり、量産性、施工性が悪いという問題があった。 However, in the air-conveying air conditioning described in Patent Document 1, conditioned air cannot flow outside the ceiling. However, even if it can be handled, it will be air-conditioned with air with reduced sensible heat capacity, so when the air conditioning load increases due to the start of operation, outdoor air, bathing, etc. Due to the lack of sensible heat capacity, there was a problem that the temperature and humidity were not stable, or it took a long time to stabilize.
In addition, there is a possibility that dust and the like may accumulate in the chamber above the ceiling, making maintenance difficult and making it difficult to keep the inside of the building, including the inside of the ceiling, clean.
In addition, in the central air-conditioning system described in

In addition, in the building unit and building described in
In addition, since the flow of return air from the building is also unclear, there is also the problem that the air conditioning load and the air blowing load increase, and the power consumption of the air conditioner and air blower may also increase.
In addition, in the air duct and air blowing system described in

本発明の空調換気システムは上記目的を達成するために、高気密高断熱な建物内の部屋及び空間に吹出口を設け、前記建物内に設けられた空調ユニットと前記吹出口を空調送風路で繋ぎ、前記空調送風路は気密性を有する筐体であり、前記空調送風路の周囲で、前記建物の外皮との間に、それぞれ前記部屋、前記空間、断熱材の少なくともいずれか一つを設け、前記空調ユニットで清浄された空調空気を作り、前記空調ユニットから前記吹出口に前記清浄された空調空気が流れ、前記吹出口が設けられた前記部屋及び前記空間から前記空調ユニットに戻ってくる風路を循環路としたものであって、前記空調ユニット内に、前記循環路の上流から下流に向けて順に、吸込部、空調部及び送風部を設け、前記吸込部、前記空調部、前記送風部に、それぞれフィルタ部A、フィルタ部B、フィルタ部Cを設け、前記循環路を通って、前記吸込部から吸い込まれた空気が、前記フィルタ部Aにより清浄され、前記空調部と前記フィルタ部Bにより空調及び清浄されて、前記空調送風路の周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の空調空気が作られ、前記送風部と前記フィルタ部Cにより、前記空調空気をさらに清浄しながら、前記吹出口に向けて、前記清浄された空調空気を前記空調送風路内に送風することにより、前記循環路を通って、前記部屋及び前記空間を空調及び空気清浄し、室外から前記循環路又は前記空調ユニットに室外空気を導入する室外空気導入路を設け、前記室外空気導入路に導入ファンとフィルタを設けて、導入する前記室外空気を清浄し、前記循環路、前記吹出口を設けない前記部屋又は前記吹出口を設けない前記空間の少なくともいずれか一つから室外へ前記建物内の空気を排出する室内空気排出路を設け、前記室内空気排出路に排気ファンを設けて、前記循環路の空気の一部又は前記建物内に滞留する前記空気の一部の少なくとも一つを室外に排出するものである。
この手段により、吸込部、空調部及び送風部を設けた空調ユニットで作り出された、空調送風路周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の空調空気を大風量で空調送風路内に送風することにより、部屋及び空間の吹出口から吹き出し、高気密高断熱な建物内の部屋及び上下の空間を空調するので、日射負荷などの空調負荷の大きい空間も含めて、建物内は快適で均一な温湿度となりやすい。そして、空調送風路は、周囲を空調された部屋、空間又は断熱材で囲まれているため、冷房時の空調送風路内外の結露、暖房時の空調送風路内の結露は発生しにくい空調換気システムが得られる。
また、空調空気を作り出す空調ユニットの吸込部に設けた還気口フィルタ(フィルタ部A)により、空調ユニットに吸い込まれる空気の全てが清浄され、さらに空調部に吸い込まれた空気は、空調部フィルタ(フィルタ部B)でさらに清浄し、複数の送風部の送風部フィルタ(フィルタ部C)で、空調ユニットに吸い込まれた空気の全てを漏れなく清浄し、空調送風路に流入させ、建物内の空気を清浄し、空調送風路に、カビの繁殖条件の一つである埃等が流入するリスクがさらに減少し、全てのフィルタ部A、B、Cが空調ユニット内にあるため、清掃などのメンテナンスしやすい空調換気システムが得られる。
また、室外空気導入路に導入ファンとフィルタを設けて、導入する室外空気を清浄し、吹出口を設けない、いわゆるダーティ―ゾーン(トイレ、洗面所等)から室外に通じる室内空気排出路から、排気ファンにより、部屋及び空間を空調した空気の一部とダーティ―ゾーンの空気を室外に排出することにより、清浄された室外空気を導入し、埃や水分で汚れた建物内の空気を排出しながら、建物内を換気できる空調換気システムが得られる。
さらに、建物内で、人間が発生する水分以外で、入浴や調理により水分を発生する浴室と台所等の空気は、室外へ排出する排気ファンを設けることにより、建物内にそれらの水分が滞留せず、空調空気に含まれないため、空調送風路内にそれらの水分が流れこまない。
これらにより、空調送風路内に、埃や水分や結露水等が堆積、滞留しないので、カビも繁殖しにくく、雑菌による臭いも発生しにくく、建物内に、空調送風路内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。そして、長期間使用しても、空調送風路の清掃などのメンテナンスが不要で、建物内を常に健康で快適な空調換気を行うことが可能な空調換気システムが得られる。
また他の手段は、前記空調ユニット内の前記空調部と複数の前記送風部の間に、さらに混合部を設け、前記空調部から吹き出された吹出空気と前記吸込部から吸い込まれた前記空気の一部の残りが、複数の前記送風部により、前記フィルタ部Cの上流にある前記混合部にて混合されて、前記清浄された空調空気が作られ、複数の前記送風部の合計風量は前記空調部の風量より多く、前記送風部の風量はゼロではないこととするものである。
この手段により、空調ユニットの送風部により、吸込部から吸い込まれる空気の一部が、空調部に吸い込まれ、空調され、吹き出される。そして、吸込部から吸い込まれた空気の一部が、空調部に吸い込まれず、空調部からの吹出空気と混合部で合流し、混合され、空調部の風量、設定温度、送風部の風量等を調整して、空調送風路周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、その空調空気を空調送風路に通すので、空調送風路に結露しにくい空調換気システムが得られる。
さらに、空調部の風量に対し、送風部の風量が大幅に多く、部屋及び空間の温度に対しても、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、部屋及び空間の温度がオーバーシュートするなど大幅に変動せず、長時間安定して、空調部の吸込空気の温度が、設定温度に近いため、特に夏季の冷房運転時は、空調部は、小温度差でのサーモON状態が長時間継続し、圧縮機が低周波数で継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、冷房運転時、さらに空調送風路に結露しにくい空調換気システムが得られる。
そして、送風部の風量はゼロではなく、常に空調空気を流し続ける仕様としているので、空調送風路内に結露した場合でも、できる限り早く蒸発させることができる。
さらに、空調部の圧縮機等を駆動させることにより、単位風量当たりのランニングコストが高い空調部の風量よりも、単位風量当たりのランニングコストが大幅に低い送風部の風量を多くして、空調空気を作り、空調送風路を通すシステムのため、省エネである。
また他の手段は、前記送風部と前記空調送風路を直接繋ぎ、前記空調送風路と前記吹出口を直接繋ぎ、前記空調送風路は、前記建物の上の階と下の階の間に設けたこととするものである。
この手段により、空調空気が流れる空調送風路が、2階建て以上の住宅では通常構造上必然的に区画され、存在する1階と2階の間の階間に設けられ、空調送風路の表面積の多くを占める上下面を空調された部屋、空間に囲まれるので、わざわざ断熱材で囲う必要がなく、前後左右は、外壁に設けられた断熱材等に囲まれるので、空調送風路の結露がさらに発生しにくく、空調送風路の空調空気の入口から吹出口までの熱損失が少ない高効率な空調換気システムが得られる。
また、例えば空調ユニットを階間の上階に設けて、階間に設けられた空調送風路と直接繋げ、空調送風路の上階の床と繋がる部分に吹出口を設け、空調送風路の下階の天井に繋がる部分にも吹出口を設け、上階の床と下階の天井から、部屋や空間に空調空気を吹き出して、空調するので、空調ユニットから吹出口までの送風路が、最短距離で略真直ぐであり、途中の圧力損失が少ない、熱損失も少ない、省施工で合理的な構造の空調換気システムが得られる。
また他の手段は、前記空調部に再熱除湿機能を有するものである。
この手段により、再熱除湿運転時、一方の熱交換器が低温低圧の冷媒が流れる蒸発器として、もう一方の熱交換器が中温中圧の冷媒が流れる再熱器として機能するため、吸込空気の温度以上で、絶対湿度の低い吹出空気となり、吹出口から吹き出されることにより、空調部は、再熱除湿サーモON状態が長時間継続し、圧縮機が継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、梅雨時期など中温高湿時等で、さらに空調送風路に結露しにくい空調換気システムが得られる。
また、他の手段は、前記循環路又は前記空調ユニットに、HEPAフィルタ式又は、電気集塵式の空気清浄機を設けるものである。
循環路又は空調ユニットにHEPAフィルタ式又は、電気集塵式の空気清浄機を設け、空調空気に含まれるカビ胞子レベルの粒子も除去するため、空調空気が通る空調送風路内にカビがより繁殖しにくく、建物内に、空調送風路内のカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる空調換気システムが得られる。
また、他の手段は、前記部屋又は前記空間の温度を検出する温度センサーと、前記温度を設定する温度設定部を有し、前記混合部の温度を検出する温度センサーを有し、2つの前記温度センサーの検出値と前記温度設定部の設定温度から、前記空調部と前記送風部を制御する制御部を有するものである。
この手段により、自動的に、部屋、空間の平均温度が設定温度となるので利便性が高く、空調送風路の周囲の空気の平均温度に対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるので、部屋、空間をユーザーの設定した温度にしながら、空調送風路内外の結露を抑えることができ、外乱や空調負荷の変化等があっても、確実にカビ等が繁殖しにくい空調換気システムが得られる。
また、他の手段は、前記空調送風路の内側の前記空調空気が流れる表面に、ポリプロピレンフィルム、軟質塩化ビニルフィルム又はPETフィルムの少なくともいずれか一つを有するものである。
これにより、空調送風路の内側の空調空気が流れる表面に、非通気性、非透湿性で、表面粗さ(表面の凹凸)が小さい、ポリプロピレンフィルム、軟質塩化ビニルフィルム又はPETフィルムの少なくともいずれか一つを有するので、埃と水分とカビ胞子等が表面から木材や断熱材、吸音材等に入り込まず、そこでカビ等が繁殖しにくく、さらに表面に、埃等が堆積しにくく、水分も含まないので、カビ等が繁殖しにくく、建物内に、空調送風路内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる空調換気システムが得られる。 In order to achieve the above object, the air-conditioning and ventilation system of the present invention provides air outlets in rooms and spaces in a highly airtight and highly insulated building, and air conditioning units provided in the building and the air outlets are connected by an air-conditioning air duct. At least one of the room, the space, and a heat insulating material is provided between the air-conditioning duct and the outer skin of the building around the air-conditioning duct. , the air-conditioning unit produces cleaned conditioned air, the cleaned conditioned air flows from the air-conditioning unit to the air outlet, and returns to the air-conditioning unit from the room and the space in which the air outlet is provided. An air passage is used as a circulation passage, and a suction section, an air conditioning section, and a blow section are provided in order from upstream to downstream of the circulation passage in the air conditioning unit, and the suction section, the air conditioning section, and the The blowing section is provided with a filter section A, a filter section B, and a filter section C, respectively. Air-conditioned and cleaned by the part B, the temperature of the air around the air-conditioned air passage is within 5K during cooling and within 10K during heating. While further purifying the conditioned air, the cleaned conditioned air is blown into the conditioned air passage toward the outlet, so that the room and the space are conditioned and air-conditioned through the circulation passage. An outdoor air introduction passage is provided for introducing outdoor air from the outdoor into the circulation passage or the air conditioning unit, and an introduction fan and a filter are provided in the outdoor air introduction passage to clean the introduced outdoor air and circulate it. An indoor air discharge path is provided for discharging the air in the building to the outside from at least one of the room without the air outlet, or the space without the air outlet, and the air is discharged to the indoor air discharge path. A fan is provided to exhaust at least one of a part of the air in the circulation path and a part of the air stagnating in the building to the outside.
By this means, the temperature of the air around the air-conditioning blast path produced by the air-conditioning unit provided with the suction part, the air-conditioning part, and the blowing part is within 5K during cooling and within 10K during heating. By blowing air into the air-conditioning air duct, air is blown out from the outlets of the rooms and spaces, and the rooms and upper and lower spaces in the highly airtight and highly insulated building are air-conditioned. , the inside of the building tends to have a comfortable and uniform temperature and humidity. In addition, since the air-conditioning duct is surrounded by an air-conditioned room, space, or heat insulating material, dew condensation inside and outside the air-conditioning duct during cooling and inside the air-conditioning duct during heating is unlikely to occur. system is obtained.
In addition, the return air filter (filter section A) provided in the intake section of the air conditioning unit that produces conditioned air cleans all of the air that is sucked into the air conditioning unit. (Filter section B) further purifies, and with the blow section filters (filter section C) of a plurality of blow sections, all of the air sucked into the air conditioning unit is cleaned without omission, flowed into the air conditioning blow path, and the air inside the building It purifies the air, further reduces the risk of dust, which is one of the breeding conditions for mold, entering the air conditioning duct, and since all the filter parts A, B, and C are inside the air conditioning unit, it is easy to clean. An easy-to-maintain air-conditioning and ventilation system is obtained.
In addition, by installing an introduction fan and a filter in the outdoor air introduction path, the outdoor air to be introduced is cleaned, and from the indoor air discharge path leading to the outside from the so-called dirty zone (toilet, washroom, etc.) without an air outlet, An exhaust fan exhausts part of the air that has conditioned the room and space and the air in the dirty zone to the outside, introducing clean outdoor air and exhausting the air inside the building that is contaminated with dust and moisture. It is possible to obtain an air-conditioning and ventilation system capable of ventilating the inside of a building.
Furthermore, in addition to the moisture generated by humans, the air in the bathrooms and kitchens, etc., which generate moisture from bathing and cooking in the building, is provided with an exhaust fan that exhausts it to the outside of the building so that the moisture stays in the building. Since the moisture is not included in the conditioned air, the moisture does not flow into the conditioned air passage.
As a result, dust, moisture, condensed water, etc., do not accumulate or accumulate in the air-conditioning air duct, preventing the growth of mold and odors caused by various bacteria. It is difficult for bacteria and odors to enter, and a healthy and comfortable space can be realized. Thus, it is possible to obtain an air-conditioning/ventilation system that does not require maintenance such as cleaning of the air-conditioning air duct even if used for a long period of time, and that can always air-condition and ventilate the inside of the building in a healthy and comfortable manner.
Another means is to further provide a mixing section between the air conditioning section and the plurality of air blowing sections in the air conditioning unit so that the air blown out from the air conditioning section and the air sucked in from the suction section are mixed. A part of the remainder is mixed by the plurality of blowing units in the mixing unit upstream of the filter unit C to produce the cleaned conditioned air, and the total air volume of the plurality of blowing units is the above It is assumed that the air volume of the air blower is greater than the air volume of the air conditioning unit and is not zero.
With this means, part of the air sucked from the intake section is sucked into the air conditioning unit, air-conditioned, and blown out by the air blowing section of the air conditioning unit. A part of the air sucked from the suction part is not sucked into the air conditioning part, but joins and mixes with the air blown from the air conditioning part in the mixing part, and the air volume of the air conditioning part, the set temperature, the air volume of the blowing part, etc. By adjusting the temperature of the air around the air-conditioning air duct, it is possible to stably create conditioned air with a large volume of air within 5K during cooling and within 10K during heating with energy saving. Since it is passed through the air duct, it is possible to obtain an air-conditioning and ventilation system in which dew condensation is less likely to occur in the air-conditioning air duct.
Furthermore, the air volume of the air blower is much larger than the air volume of the air conditioning unit, and the temperature of the room and space is within 5K during cooling and within 10K during heating. It can be produced stably, and the temperature of the room and space does not fluctuate significantly, such as overshooting, and it is stable for a long time. In the air conditioning unit, the thermo ON state continues for a long time with a small temperature difference, and the compressor continues to operate at a low frequency. As a result, the moisture in the intake air condenses on the evaporator, the amount of dehumidification removed increases due to long-term operation, the absolute humidity of the blown air continues for a long time, and the absolute humidity of the conditioned air also decreases. The relative humidity in the air-conditioning air duct, the room, and the space through which the conditioned air flows is also reduced, and an air-conditioning/ventilating system in which dew condensation is less likely to occur in the air-conditioning air-conditioning air duct during cooling operation can be obtained.
The air volume of the air blower is not zero, and the specification is such that the conditioned air always flows, so even if dew condensation occurs in the air conditioned air passage, it can be evaporated as quickly as possible.
Furthermore, by driving the compressor or the like of the air conditioning unit, the air volume of the air blowing unit whose running cost per unit air volume is significantly lower than the air volume of the air conditioning unit whose running cost per unit air volume is high is increased. It is energy-saving because it is a system that creates air-conditioning air ducts.
Another means is to directly connect the air blower and the air-conditioning air passage, directly connect the air-conditioning air passage and the outlet, and provide the air-conditioning air passage between the upper floor and the lower floor of the building. This is what I did.
By this means, the air-conditioning duct through which the conditioned air flows is inevitably divided structurally in a two-story house or more, and is provided between the existing first and second floors, and the surface area of the conditioned air duct is Since the upper and lower surfaces, which account for most of the space, are surrounded by air-conditioned rooms and spaces, there is no need to enclose them with heat insulating materials. Furthermore, it is possible to obtain a highly efficient air-conditioning and ventilation system in which heat loss is less likely to occur and heat loss from the air-conditioning air inlet of the air-conditioning air passage to the air outlet is small.
In addition, for example, an air conditioning unit is provided on the upper floor between floors, directly connected to the air conditioning ventilation passage provided between floors, and an air outlet is provided in the part connected to the floor above the air conditioning ventilation passage, and below the air conditioning ventilation passage Air outlets are also provided in the part that connects to the ceiling of the floor, and the conditioned air is blown out from the floor of the upper floor and the ceiling of the lower floor to the room or space for air conditioning, so the air path from the air conditioning unit to the air outlet is the shortest. It is possible to obtain an air-conditioning/ventilation system that is substantially straight in a distance, has little pressure loss along the way, has little heat loss, and has a construction-saving and rational structure.
Another means is to have a reheat dehumidifying function in the air conditioning unit.
With this means, during reheat dehumidification operation, one heat exchanger functions as an evaporator through which low-temperature and low-pressure refrigerant flows, and the other heat exchanger functions as a reheater through which medium-temperature and medium-pressure refrigerant flows. above the temperature, the blown air has a low absolute humidity. The surface temperature of the evaporator, the so-called evaporation temperature, falls below the dew point temperature of the intake air, and moisture in the intake air condenses on the evaporator. The absolute humidity of the air decreases, the absolute humidity of the conditioned air also decreases, and the relative humidity of the air-conditioned air passages, rooms, and spaces in which the conditioned air flows also decreases. An air-conditioning and ventilation system that is less likely to condense on roads can be obtained.
Another means is to provide an air purifier of HEPA filter type or electrostatic precipitator type in the circulation path or the air conditioning unit.
A HEPA filter type or electric dust collection type air purifier is installed in the circulation path or air conditioning unit to remove mold spore level particles contained in the air conditioning air, so that mold grows more in the air conditioning ventilation path through which the air conditioning air passes. This provides an air-conditioning/ventilation system that is difficult to clean and mold, bacteria, and offensive odors in the air-conditioning air duct do not easily enter the building, and that can realize a healthy and comfortable space.
Further, another means has a temperature sensor for detecting the temperature of the room or the space, a temperature setting section for setting the temperature, a temperature sensor for detecting the temperature of the mixing section, and the two It has a control unit for controlling the air conditioning unit and the blower unit based on the detected value of the temperature sensor and the set temperature of the temperature setting unit.
By this means, the average temperature of the room and space automatically becomes the set temperature, which is highly convenient. The average temperature of the air in the air conditioning duct can be set by the user, and dew condensation inside and outside the air conditioning duct can be suppressed. It is possible to obtain an air-conditioning and ventilation system in which mold and the like are less likely to propagate.
Another means is to have at least one of a polypropylene film, a soft vinyl chloride film, and a PET film on the surface inside the air-conditioning air passage through which the air-conditioning air flows.
As a result, at least one of a polypropylene film, a soft vinyl chloride film, or a PET film, which is impermeable, non-moisture permeable, and has a small surface roughness (unevenness on the surface), is applied to the surface inside the air conditioning air passage where the conditioned air flows. Since it has one, dust, moisture, mold spores, etc. do not enter the wood, heat insulating material, sound absorbing material, etc. from the surface, and it is difficult for mold to propagate there. Therefore, it is difficult for mold and the like to grow, and dust, mold, bacteria, odors, and the like in the air-conditioning air duct hardly enter the building, and an air-conditioning/ventilation system capable of realizing a healthy and comfortable space can be obtained.
この手段により、吸込部、空調部及び送風部を設けた空調ユニットで作り出された、空調送風路周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の空調空気を大風量で空調送風路内に送風することにより、部屋及び空間の吹出口から吹き出し、高気密高断熱な建物内の部屋及び上下の空間を空調するので、日射負荷などの空調負荷の大きい空間も含めて、建物内は快適で均一な温湿度となりやすい。そして、空調送風路は、周囲を空調された部屋、空間又は断熱材で囲まれているため、冷房時の空調送風路内外の結露、暖房時の空調送風路内の結露は発生しにくい空調換気システムが得られる。
また、空調空気を作り出す空調ユニットの吸込部に設けた還気口フィルタ(フィルタ部A)により、空調ユニットに吸い込まれる空気の全てが清浄され、さらに空調部に吸い込まれた空気は、空調部フィルタ(フィルタ部B)でさらに清浄し、複数の送風部の送風部フィルタ(フィルタ部C)で、空調ユニットに吸い込まれた空気の全てを漏れなく清浄し、空調送風路に流入させ、建物内の空気を清浄し、空調送風路に、カビの繁殖条件の一つである埃等が流入するリスクがさらに減少し、全てのフィルタ部A、B、Cが空調ユニット内にあるため、清掃などのメンテナンスしやすい空調換気システムが得られる。
また、室外空気導入路に導入ファンとフィルタを設けて、導入する室外空気を清浄し、吹出口を設けない、いわゆるダーティ―ゾーン(トイレ、洗面所等)から室外に通じる室内空気排出路から、排気ファンにより、部屋及び空間を空調した空気の一部とダーティ―ゾーンの空気を室外に排出することにより、清浄された室外空気を導入し、埃や水分で汚れた建物内の空気を排出しながら、建物内を換気できる空調換気システムが得られる。
さらに、建物内で、人間が発生する水分以外で、入浴や調理により水分を発生する浴室と台所等の空気は、室外へ排出する排気ファンを設けることにより、建物内にそれらの水分が滞留せず、空調空気に含まれないため、空調送風路内にそれらの水分が流れこまない。
これらにより、空調送風路内に、埃や水分や結露水等が堆積、滞留しないので、カビも繁殖しにくく、雑菌による臭いも発生しにくく、建物内に、空調送風路内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。そして、長期間使用しても、空調送風路の清掃などのメンテナンスが不要で、建物内を常に健康で快適な空調換気を行うことが可能な空調換気システムが得られる。
また他の手段は、前記空調ユニット内の前記空調部と複数の前記送風部の間に、さらに混合部を設け、前記空調部から吹き出された吹出空気と前記吸込部から吸い込まれた前記空気の一部の残りが、複数の前記送風部により、前記フィルタ部Cの上流にある前記混合部にて混合されて、前記清浄された空調空気が作られ、複数の前記送風部の合計風量は前記空調部の風量より多く、前記送風部の風量はゼロではないこととするものである。
この手段により、空調ユニットの送風部により、吸込部から吸い込まれる空気の一部が、空調部に吸い込まれ、空調され、吹き出される。そして、吸込部から吸い込まれた空気の一部が、空調部に吸い込まれず、空調部からの吹出空気と混合部で合流し、混合され、空調部の風量、設定温度、送風部の風量等を調整して、空調送風路周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、その空調空気を空調送風路に通すので、空調送風路に結露しにくい空調換気システムが得られる。
さらに、空調部の風量に対し、送風部の風量が大幅に多く、部屋及び空間の温度に対しても、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、部屋及び空間の温度がオーバーシュートするなど大幅に変動せず、長時間安定して、空調部の吸込空気の温度が、設定温度に近いため、特に夏季の冷房運転時は、空調部は、小温度差でのサーモON状態が長時間継続し、圧縮機が低周波数で継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、冷房運転時、さらに空調送風路に結露しにくい空調換気システムが得られる。
そして、送風部の風量はゼロではなく、常に空調空気を流し続ける仕様としているので、空調送風路内に結露した場合でも、できる限り早く蒸発させることができる。
さらに、空調部の圧縮機等を駆動させることにより、単位風量当たりのランニングコストが高い空調部の風量よりも、単位風量当たりのランニングコストが大幅に低い送風部の風量を多くして、空調空気を作り、空調送風路を通すシステムのため、省エネである。
また他の手段は、前記送風部と前記空調送風路を直接繋ぎ、前記空調送風路と前記吹出口を直接繋ぎ、前記空調送風路は、前記建物の上の階と下の階の間に設けたこととするものである。
この手段により、空調空気が流れる空調送風路が、2階建て以上の住宅では通常構造上必然的に区画され、存在する1階と2階の間の階間に設けられ、空調送風路の表面積の多くを占める上下面を空調された部屋、空間に囲まれるので、わざわざ断熱材で囲う必要がなく、前後左右は、外壁に設けられた断熱材等に囲まれるので、空調送風路の結露がさらに発生しにくく、空調送風路の空調空気の入口から吹出口までの熱損失が少ない高効率な空調換気システムが得られる。
また、例えば空調ユニットを階間の上階に設けて、階間に設けられた空調送風路と直接繋げ、空調送風路の上階の床と繋がる部分に吹出口を設け、空調送風路の下階の天井に繋がる部分にも吹出口を設け、上階の床と下階の天井から、部屋や空間に空調空気を吹き出して、空調するので、空調ユニットから吹出口までの送風路が、最短距離で略真直ぐであり、途中の圧力損失が少ない、熱損失も少ない、省施工で合理的な構造の空調換気システムが得られる。
また他の手段は、前記空調部に再熱除湿機能を有するものである。
この手段により、再熱除湿運転時、一方の熱交換器が低温低圧の冷媒が流れる蒸発器として、もう一方の熱交換器が中温中圧の冷媒が流れる再熱器として機能するため、吸込空気の温度以上で、絶対湿度の低い吹出空気となり、吹出口から吹き出されることにより、空調部は、再熱除湿サーモON状態が長時間継続し、圧縮機が継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、梅雨時期など中温高湿時等で、さらに空調送風路に結露しにくい空調換気システムが得られる。
また、他の手段は、前記循環路又は前記空調ユニットに、HEPAフィルタ式又は、電気集塵式の空気清浄機を設けるものである。
循環路又は空調ユニットにHEPAフィルタ式又は、電気集塵式の空気清浄機を設け、空調空気に含まれるカビ胞子レベルの粒子も除去するため、空調空気が通る空調送風路内にカビがより繁殖しにくく、建物内に、空調送風路内のカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる空調換気システムが得られる。
また、他の手段は、前記部屋又は前記空間の温度を検出する温度センサーと、前記温度を設定する温度設定部を有し、前記混合部の温度を検出する温度センサーを有し、2つの前記温度センサーの検出値と前記温度設定部の設定温度から、前記空調部と前記送風部を制御する制御部を有するものである。
この手段により、自動的に、部屋、空間の平均温度が設定温度となるので利便性が高く、空調送風路の周囲の空気の平均温度に対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるので、部屋、空間をユーザーの設定した温度にしながら、空調送風路内外の結露を抑えることができ、外乱や空調負荷の変化等があっても、確実にカビ等が繁殖しにくい空調換気システムが得られる。
また、他の手段は、前記空調送風路の内側の前記空調空気が流れる表面に、ポリプロピレンフィルム、軟質塩化ビニルフィルム又はPETフィルムの少なくともいずれか一つを有するものである。
これにより、空調送風路の内側の空調空気が流れる表面に、非通気性、非透湿性で、表面粗さ(表面の凹凸)が小さい、ポリプロピレンフィルム、軟質塩化ビニルフィルム又はPETフィルムの少なくともいずれか一つを有するので、埃と水分とカビ胞子等が表面から木材や断熱材、吸音材等に入り込まず、そこでカビ等が繁殖しにくく、さらに表面に、埃等が堆積しにくく、水分も含まないので、カビ等が繁殖しにくく、建物内に、空調送風路内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる空調換気システムが得られる。 In order to achieve the above object, the air-conditioning and ventilation system of the present invention provides air outlets in rooms and spaces in a highly airtight and highly insulated building, and air conditioning units provided in the building and the air outlets are connected by an air-conditioning air duct. At least one of the room, the space, and a heat insulating material is provided between the air-conditioning duct and the outer skin of the building around the air-conditioning duct. , the air-conditioning unit produces cleaned conditioned air, the cleaned conditioned air flows from the air-conditioning unit to the air outlet, and returns to the air-conditioning unit from the room and the space in which the air outlet is provided. An air passage is used as a circulation passage, and a suction section, an air conditioning section, and a blow section are provided in order from upstream to downstream of the circulation passage in the air conditioning unit, and the suction section, the air conditioning section, and the The blowing section is provided with a filter section A, a filter section B, and a filter section C, respectively. Air-conditioned and cleaned by the part B, the temperature of the air around the air-conditioned air passage is within 5K during cooling and within 10K during heating. While further purifying the conditioned air, the cleaned conditioned air is blown into the conditioned air passage toward the outlet, so that the room and the space are conditioned and air-conditioned through the circulation passage. An outdoor air introduction passage is provided for introducing outdoor air from the outdoor into the circulation passage or the air conditioning unit, and an introduction fan and a filter are provided in the outdoor air introduction passage to clean the introduced outdoor air and circulate it. An indoor air discharge path is provided for discharging the air in the building to the outside from at least one of the room without the air outlet, or the space without the air outlet, and the air is discharged to the indoor air discharge path. A fan is provided to exhaust at least one of a part of the air in the circulation path and a part of the air stagnating in the building to the outside.
By this means, the temperature of the air around the air-conditioning blast path produced by the air-conditioning unit provided with the suction part, the air-conditioning part, and the blowing part is within 5K during cooling and within 10K during heating. By blowing air into the air-conditioning air duct, air is blown out from the outlets of the rooms and spaces, and the rooms and upper and lower spaces in the highly airtight and highly insulated building are air-conditioned. , the inside of the building tends to have a comfortable and uniform temperature and humidity. In addition, since the air-conditioning duct is surrounded by an air-conditioned room, space, or heat insulating material, dew condensation inside and outside the air-conditioning duct during cooling and inside the air-conditioning duct during heating is unlikely to occur. system is obtained.
In addition, the return air filter (filter section A) provided in the intake section of the air conditioning unit that produces conditioned air cleans all of the air that is sucked into the air conditioning unit. (Filter section B) further purifies, and with the blow section filters (filter section C) of a plurality of blow sections, all of the air sucked into the air conditioning unit is cleaned without omission, flowed into the air conditioning blow path, and the air inside the building It purifies the air, further reduces the risk of dust, which is one of the breeding conditions for mold, entering the air conditioning duct, and since all the filter parts A, B, and C are inside the air conditioning unit, it is easy to clean. An easy-to-maintain air-conditioning and ventilation system is obtained.
In addition, by installing an introduction fan and a filter in the outdoor air introduction path, the outdoor air to be introduced is cleaned, and from the indoor air discharge path leading to the outside from the so-called dirty zone (toilet, washroom, etc.) without an air outlet, An exhaust fan exhausts part of the air that has conditioned the room and space and the air in the dirty zone to the outside, introducing clean outdoor air and exhausting the air inside the building that is contaminated with dust and moisture. It is possible to obtain an air-conditioning and ventilation system capable of ventilating the inside of a building.
Furthermore, in addition to the moisture generated by humans, the air in the bathrooms and kitchens, etc., which generate moisture from bathing and cooking in the building, is provided with an exhaust fan that exhausts it to the outside of the building so that the moisture stays in the building. Since the moisture is not included in the conditioned air, the moisture does not flow into the conditioned air passage.
As a result, dust, moisture, condensed water, etc., do not accumulate or accumulate in the air-conditioning air duct, preventing the growth of mold and odors caused by various bacteria. It is difficult for bacteria and odors to enter, and a healthy and comfortable space can be realized. Thus, it is possible to obtain an air-conditioning/ventilation system that does not require maintenance such as cleaning of the air-conditioning air duct even if used for a long period of time, and that can always air-condition and ventilate the inside of the building in a healthy and comfortable manner.
Another means is to further provide a mixing section between the air conditioning section and the plurality of air blowing sections in the air conditioning unit so that the air blown out from the air conditioning section and the air sucked in from the suction section are mixed. A part of the remainder is mixed by the plurality of blowing units in the mixing unit upstream of the filter unit C to produce the cleaned conditioned air, and the total air volume of the plurality of blowing units is the above It is assumed that the air volume of the air blower is greater than the air volume of the air conditioning unit and is not zero.
With this means, part of the air sucked from the intake section is sucked into the air conditioning unit, air-conditioned, and blown out by the air blowing section of the air conditioning unit. A part of the air sucked from the suction part is not sucked into the air conditioning part, but joins and mixes with the air blown from the air conditioning part in the mixing part, and the air volume of the air conditioning part, the set temperature, the air volume of the blowing part, etc. By adjusting the temperature of the air around the air-conditioning air duct, it is possible to stably create conditioned air with a large volume of air within 5K during cooling and within 10K during heating with energy saving. Since it is passed through the air duct, it is possible to obtain an air-conditioning and ventilation system in which dew condensation is less likely to occur in the air-conditioning air duct.
Furthermore, the air volume of the air blower is much larger than the air volume of the air conditioning unit, and the temperature of the room and space is within 5K during cooling and within 10K during heating. It can be produced stably, and the temperature of the room and space does not fluctuate significantly, such as overshooting, and it is stable for a long time. In the air conditioning unit, the thermo ON state continues for a long time with a small temperature difference, and the compressor continues to operate at a low frequency. As a result, the moisture in the intake air condenses on the evaporator, the amount of dehumidification removed increases due to long-term operation, the absolute humidity of the blown air continues for a long time, and the absolute humidity of the conditioned air also decreases. The relative humidity in the air-conditioning air duct, the room, and the space through which the conditioned air flows is also reduced, and an air-conditioning/ventilating system in which dew condensation is less likely to occur in the air-conditioning air-conditioning air duct during cooling operation can be obtained.
The air volume of the air blower is not zero, and the specification is such that the conditioned air always flows, so even if dew condensation occurs in the air conditioned air passage, it can be evaporated as quickly as possible.
Furthermore, by driving the compressor or the like of the air conditioning unit, the air volume of the air blowing unit whose running cost per unit air volume is significantly lower than the air volume of the air conditioning unit whose running cost per unit air volume is high is increased. It is energy-saving because it is a system that creates air-conditioning air ducts.
Another means is to directly connect the air blower and the air-conditioning air passage, directly connect the air-conditioning air passage and the outlet, and provide the air-conditioning air passage between the upper floor and the lower floor of the building. This is what I did.
By this means, the air-conditioning duct through which the conditioned air flows is inevitably divided structurally in a two-story house or more, and is provided between the existing first and second floors, and the surface area of the conditioned air duct is Since the upper and lower surfaces, which account for most of the space, are surrounded by air-conditioned rooms and spaces, there is no need to enclose them with heat insulating materials. Furthermore, it is possible to obtain a highly efficient air-conditioning and ventilation system in which heat loss is less likely to occur and heat loss from the air-conditioning air inlet of the air-conditioning air passage to the air outlet is small.
In addition, for example, an air conditioning unit is provided on the upper floor between floors, directly connected to the air conditioning ventilation passage provided between floors, and an air outlet is provided in the part connected to the floor above the air conditioning ventilation passage, and below the air conditioning ventilation passage Air outlets are also provided in the part that connects to the ceiling of the floor, and the conditioned air is blown out from the floor of the upper floor and the ceiling of the lower floor to the room or space for air conditioning, so the air path from the air conditioning unit to the air outlet is the shortest. It is possible to obtain an air-conditioning/ventilation system that is substantially straight in a distance, has little pressure loss along the way, has little heat loss, and has a construction-saving and rational structure.
Another means is to have a reheat dehumidifying function in the air conditioning unit.
With this means, during reheat dehumidification operation, one heat exchanger functions as an evaporator through which low-temperature and low-pressure refrigerant flows, and the other heat exchanger functions as a reheater through which medium-temperature and medium-pressure refrigerant flows. above the temperature, the blown air has a low absolute humidity. The surface temperature of the evaporator, the so-called evaporation temperature, falls below the dew point temperature of the intake air, and moisture in the intake air condenses on the evaporator. The absolute humidity of the air decreases, the absolute humidity of the conditioned air also decreases, and the relative humidity of the air-conditioned air passages, rooms, and spaces in which the conditioned air flows also decreases. An air-conditioning and ventilation system that is less likely to condense on roads can be obtained.
Another means is to provide an air purifier of HEPA filter type or electrostatic precipitator type in the circulation path or the air conditioning unit.
A HEPA filter type or electric dust collection type air purifier is installed in the circulation path or air conditioning unit to remove mold spore level particles contained in the air conditioning air, so that mold grows more in the air conditioning ventilation path through which the air conditioning air passes. This provides an air-conditioning/ventilation system that is difficult to clean and mold, bacteria, and offensive odors in the air-conditioning air duct do not easily enter the building, and that can realize a healthy and comfortable space.
Further, another means has a temperature sensor for detecting the temperature of the room or the space, a temperature setting section for setting the temperature, a temperature sensor for detecting the temperature of the mixing section, and the two It has a control unit for controlling the air conditioning unit and the blower unit based on the detected value of the temperature sensor and the set temperature of the temperature setting unit.
By this means, the average temperature of the room and space automatically becomes the set temperature, which is highly convenient. The average temperature of the air in the air conditioning duct can be set by the user, and dew condensation inside and outside the air conditioning duct can be suppressed. It is possible to obtain an air-conditioning and ventilation system in which mold and the like are less likely to propagate.
Another means is to have at least one of a polypropylene film, a soft vinyl chloride film, and a PET film on the surface inside the air-conditioning air passage through which the air-conditioning air flows.
As a result, at least one of a polypropylene film, a soft vinyl chloride film, or a PET film, which is impermeable, non-moisture permeable, and has a small surface roughness (unevenness on the surface), is applied to the surface inside the air conditioning air passage where the conditioned air flows. Since it has one, dust, moisture, mold spores, etc. do not enter the wood, heat insulating material, sound absorbing material, etc. from the surface, and it is difficult for mold to propagate there. Therefore, it is difficult for mold and the like to grow, and dust, mold, bacteria, odors, and the like in the air-conditioning air duct hardly enter the building, and an air-conditioning/ventilation system capable of realizing a healthy and comfortable space can be obtained.

The length of the muffling ducts 47 and 48 may be adjusted according to the degree of noise.
Blower fans 45 and 46 and noise reduction ducts 47 and 48 are connected to the outlets 40 and 41. The purpose of the fan is to increase the amount of air from the outlets 40 and 41, as will be described later. Since the purpose of the muffling duct is to stabilize the performance of the noise fan and to muffle the noise, the airflow path B31 and the outlets 40 and 41 are directly connected.
In this embodiment, thenoise reduction ducts 47 and 48 are connected to the blower fans 45 and 46. Noise propagation (crosstalk) from rooms and other floors can be prevented.
In this embodiment, air outlets are provided in room A23 and room B24 as living rooms.

It is spread horizontally so as to be connected, and theentire building 2 is air-conditioned and ventilated.
When the outlet on the ceiling 32 side of the first floor and the outlet on thefloor 33 side of the second floor, which are connected to the air conditioning fan path B31, overlap each other with the air conditioning fan path B31 interposed therebetween when the building 2 is viewed from above, 1 Noise from the floor can be heard on the second floor, or vice versa (crosstalk) may increase, making it difficult to protect privacy. Crosstalk noise can be reduced by providing an interval of 2 m or more. As an example, there was a difference of about 3 dB between the noise at 1 m directly below the outlet on the first floor and the noise at 1 m directly above the outlet on the second floor.
また、送風ファン45、46には、送風ファンの性能の安定化と送風ファン自体の騒音低減、送風部17他の送風音の伝搬や他の部屋、他の階からの騒音の伝搬(クロストーク)を防止するために、1mの消音ダクト47、48を接続している。なお、消音ダクト47、48の長さは騒音の程度により調整すればよい。
なお、吹出口40、41には、送風ファン45、46、消音ダクト47、48が繋げられているが、送風ファンの目的は、後述するが、吹出口40、41からの風量を増やす等であり、消音ダクトの目的は、騒音ファンの性能の安定化と消音のためであるので、風路として、空調送風路B31と吹出口40、41とは直接繋げられていることに変わりはない。
本実施の形態では、送風ファン45、46に消音ダクト47、48を接続しているが、吹出口42他に直接消音ダクトを接続しても、送風部17他の送風音の伝搬や他の部屋、他の階からの騒音の伝搬(クロストーク)を防止できる。
本実施の形態では、居室として、部屋A23、部屋B24に吹出口を設けているが、LDK、寝室、子供部屋、仕事部屋、洗面所、トイレ、浴室、台所等に設けてもよく、非居室として、玄関13に吹出口を設けているが、2階ホール15、階段下16、屋根裏空間9、床下空間12、機械室、廊下、納戸、クローゼット、下駄箱等に吹出口を設けてもよい。
送風部17の吹出口22から吹き出された空調空気は、空調送風路A30から、空調送風路B31を通って、送風ファン45、46を通り、吹出口40、41、42から、部屋A23、部屋B24、玄関13に吹き出す。

階間34内で、換気排気口62から熱交換ユニット60の間を排気ダクトで繋いだ場合、階間34は上下を空調される部屋や空間で覆われ、前後左右を断熱材等で覆われた断熱空間のため、ダクト内結露の可能性は少なく、埃や水分がダクト内側に堆積、吸水しないように、ダクト内側に断熱材や不織布などを有しない、ポリプロピレン製のダクトだけで構成された非断熱ダクトを用いる。
排気ダクトA65と給気ダクトA68は、屋外排気フードA66又は屋外給気フード67から熱交換気ユニット60の間の階間34に設けられた、室外空気に接触するダクトのため、結露の可能性があり、埃等が室外から流入する可能性もあるため、断熱性、耐湿性が高く、可撓性のあるダクトを用いる。
ダクトの構成としては、外側から、順に、可撓性のある厚み0.08mm程度のポリエチレンシートなどの外部被覆材(図示せず)、厚み25mmで密度24kg/m3程度のグラスウールなどの断熱材(図示せず)、ポリエステル不織布などに対して、非通気性、非透湿性で、表面粗さ(表面の凹凸)が小さい、厚み0.1mm程度のポリプロピレンフィルム、軟質塩化ビニルフィルム、PETフィルムなどの内部被覆材(図示せず)、空気等が通過する風路(図示せず)となっており、断熱材の内側と内部被覆材の間に、ポリプロピレン樹脂などの成型用芯材(図示せず)を設けて、ダクトを折り曲げても、座屈せず、内部の風路の断面積が確保できるようになっている。
内部被覆材として、不織布の代わりに、ポリプロピレンフィルムなどを用いているのは、表面粗さが小さいため、ダクト内側表面に埃等が堆積しにくく、水分も含まないので、カビ等が繁殖しにくく、非通気性、非透湿性のため、ダクト内側表面から、埃と水分とカビ胞子等がグラスウールに入り込まず、そこでカビ等が繁殖しにくいためである。
なお、断熱材は、厚み25mmで密度24kg/m3程度のグラスウールを使用しているが、ダクトの外径が大きくなり、ダクトを通すスペースを建物2の階間34内に確保することが困難な場合、断熱材の密度を100kg/m3以上にし、厚みを10mm以下のグラスウール等にすることにより、ダクトスペースを確保してもよい。

建物2は天井断熱仕様、床断熱仕様であり、屋根裏空間9と床下空間12は非断熱空間となり、そこに、熱交換気ユニット60、フィルタボックス70、排気ダクトB65等を設置すると、それらに結露したり、性能がダウンする可能性があるため、通常は、断熱空間である部屋や廊下等の天井を一部下げるなどして設置するが、天井高さが低くなり、居室スペースが狭くなるなどの問題が生じる。
本実施の形態の空調換気システム1では、断熱空間であり、空調送風路として十分な断面積を有する階間34に、熱交換気ユニット60、フィルタボックス70、排気ダクトB65等を設置し、その下部であるトイレ61等の天井に点検口を設け、定期的な清掃や長期使用時の交換などが、容易に可能である。 In the inter-floor 34, when theventilation outlet 62 and the heat exchange unit 60 are connected by an exhaust duct, the inter-floor 34 is covered with air-conditioned rooms and spaces above and below, and is covered with heat insulating materials on the front, back, left, and right. Because it is an insulated space, there is little possibility of condensation inside the duct, and in order to prevent dust and moisture from accumulating inside the duct and absorbing water, there is no heat insulating material or non-woven fabric inside the duct. Use non-insulated ducts.
The exhaust duct A65 and the air supply duct A68 are provided in the inter-floor 34 between the outdoor exhaust hood A66 or the outdoorair supply hood 67 and the heat exchange air unit 60, and are ducts in contact with the outdoor air, so there is a possibility of condensation. Since there is a possibility that dust and the like may enter from the outside, a flexible duct with high heat insulation and moisture resistance is used.
The structure of the duct consists of, from the outside, an external covering material (not shown) such as a flexible polyethylene sheet with a thickness of about 0.08 mm, and a heat insulating material such as glass wool with a thickness of 25 mm and a density of about 24 kg/m 3 .

Polypropylene film is used instead of non-woven fabric as the inner covering material, because the surface roughness is small, so dust does not easily accumulate on the inner surface of the duct, and since it does not contain moisture, it is difficult for mold to grow. Because of the non-breathability and non-moisture permeability, dust, moisture, mold spores, and the like do not enter the glass wool from the inner surface of the duct, and mold and the like are less likely to propagate there.
Glass wool with a thickness of 25 mm and a density of about 24 kg/m 3 is used as the heat insulating material, but the outer diameter of the duct becomes large, and it is difficult to secure a space for the duct to pass through between thefloors 34 of the building 2. In such a case, the duct space may be secured by using glass wool or the like having a density of 100 kg/m 3 or more and a thickness of 10 mm or less.

Both the air
3つのフィルタ85、86、87は、いずれも埃等を捕集するのに適正な、捕集効率とメンテナンス頻度のバランスを図ったフィルタである。
還気口フィルタ85は、ポリエステル、モダクリル製の厚み15mm~30mmの不織布で、標準風速1m/sで使用し、効率(重量法)は80%以上で、洗浄により再生可能となっている。
空調部フィルタ86は、ポリプロピレン繊維をハニカム状(ハチの巣状)に織ったフィルタを樹脂枠に成形したもので、効率が低いが、圧力損失が低く、吸水性吸湿性がなく、洗浄による清掃が容易である。
送風部フィルタ87は、ポリエステル他製の厚み2mmの不織布で、標準風速2m/sで使用し、効率(重量法)30%で、圧力損失が適当で、洗浄により再生可能となっている。なお、清掃などのメンテナンスの頻度を減らしたい場合は、少し効率が下がるが、空調部フィルタ86と同じく、ポリプロピレン繊維をハニカム状に織ったフィルタを樹脂枠に成形したものとしてもよいが、圧力損失が下がりすぎて、送風部フィルタ87の上流の混合部95での空調空気の混合促進に影響がでることに注意しなければならない。
このように、空調ユニット10の入口で風路の最上流の還気口55(吸込部)、空調ユニット10内の空調部20、空調ユニット10の出口で風路の最下流の送風部17にそれぞれフィルタ部A、B、Cを設けているのは、カビの繁殖条件の一つである埃等を除去するのが、フィルタ部の主目的であり、風路の最上流から最下流に向けて、埃等を捕集するのに適正な捕集効率とメンテナンス頻度のバランスを図った3つのフィルタ部を略直列に設けているため、早期にフィルタ部が目詰まりし、圧力損失が大きくなる可能性は低く、メンテナンス頻度を抑えながら、埃等を確実に捕集できるからである。
また、空調ユニット10の入口と出口にそれぞれフィルタ部を設けているので、清浄された空気を作る空調ユニット10を通る全ての空気を1サイクルで2回清浄し、一つのフィルタ部と筐体に隙間等が発生するなどして埃等の洩れがあったとしても、埃等が空調送風路に流入することを確実に防止できるからであり、長期間使用時に、メンテナンス頻度を抑えながら、埃等の空調送風路への流入を確実に防止できる。 The three filters 85, 86, and 87 are filters that are suitable for collecting dust and the like, and have a good balance between collection efficiency and maintenance frequency.
The returnair port filter 85 is a polyester or modacrylic nonwoven fabric with a thickness of 15 mm to 30 mm, is used at a standard wind speed of 1 m/s, has an efficiency (weight method) of 80% or more, and can be recycled by washing.
The air-conditioning unit filter 86 is a filter made by weaving polypropylene fibers in a honeycomb shape (honeycomb shape) and molded in a resin frame. is easy.
Theblower filter 87 is a non-woven fabric made of polyester or the like having a thickness of 2 mm, is used at a standard wind speed of 2 m/s, has an efficiency (weight method) of 30%, a suitable pressure loss, and can be regenerated by washing. If it is desired to reduce the frequency of maintenance such as cleaning, a filter made of polypropylene fibers woven in a honeycomb shape may be formed in a resin frame, similar to the air conditioning unit filter 86, although the efficiency will be slightly reduced. is too low, and it affects the promotion of mixing of the conditioned air in the mixing section 95 upstream of the blower section filter 87 .
In this way, the most upstream return air port 55 (suction portion) of the air passage at the entrance of theair conditioning unit 10, the air conditioning unit 20 in the air conditioning unit 10, and the most downstream air blowing portion 17 of the air passage at the exit of the air conditioning unit 10 Filters A, B, and C are provided, respectively, because the main purpose of the filters is to remove dust, which is one of the breeding conditions for mold. Since three filter sections are arranged in series to achieve a proper balance between collection efficiency and maintenance frequency for collecting dust, etc., the filter sections become clogged early and the pressure loss increases. This is because the possibility is low, and dust and the like can be reliably collected while suppressing maintenance frequency.
In addition, since filter sections are provided at the inlet and outlet of the air-conditioning unit 10, respectively, all the air passing through the air-conditioning unit 10 that produces the cleaned air is cleaned twice in one cycle, and one filter section and one housing are used. This is because even if dust or the like leaks due to gaps or the like, it is possible to reliably prevent dust or the like from flowing into the air-conditioning air passage. can be reliably prevented from flowing into the air-conditioning air duct.
還気口フィルタ85は、ポリエステル、モダクリル製の厚み15mm~30mmの不織布で、標準風速1m/sで使用し、効率(重量法)は80%以上で、洗浄により再生可能となっている。
空調部フィルタ86は、ポリプロピレン繊維をハニカム状(ハチの巣状)に織ったフィルタを樹脂枠に成形したもので、効率が低いが、圧力損失が低く、吸水性吸湿性がなく、洗浄による清掃が容易である。
送風部フィルタ87は、ポリエステル他製の厚み2mmの不織布で、標準風速2m/sで使用し、効率(重量法)30%で、圧力損失が適当で、洗浄により再生可能となっている。なお、清掃などのメンテナンスの頻度を減らしたい場合は、少し効率が下がるが、空調部フィルタ86と同じく、ポリプロピレン繊維をハニカム状に織ったフィルタを樹脂枠に成形したものとしてもよいが、圧力損失が下がりすぎて、送風部フィルタ87の上流の混合部95での空調空気の混合促進に影響がでることに注意しなければならない。
このように、空調ユニット10の入口で風路の最上流の還気口55(吸込部)、空調ユニット10内の空調部20、空調ユニット10の出口で風路の最下流の送風部17にそれぞれフィルタ部A、B、Cを設けているのは、カビの繁殖条件の一つである埃等を除去するのが、フィルタ部の主目的であり、風路の最上流から最下流に向けて、埃等を捕集するのに適正な捕集効率とメンテナンス頻度のバランスを図った3つのフィルタ部を略直列に設けているため、早期にフィルタ部が目詰まりし、圧力損失が大きくなる可能性は低く、メンテナンス頻度を抑えながら、埃等を確実に捕集できるからである。
また、空調ユニット10の入口と出口にそれぞれフィルタ部を設けているので、清浄された空気を作る空調ユニット10を通る全ての空気を1サイクルで2回清浄し、一つのフィルタ部と筐体に隙間等が発生するなどして埃等の洩れがあったとしても、埃等が空調送風路に流入することを確実に防止できるからであり、長期間使用時に、メンテナンス頻度を抑えながら、埃等の空調送風路への流入を確実に防止できる。 The three

The air cleaner 90 has a prefilter and an electric dust collector.
The pre-filter is a SUS filter with a coarse mesh of about 20 to 50 mesh located upstream of the electric dust collector. Coarse particles with a particle size of 10 to 20 μm or more are removed and passed through an electric dust collector.
The pre-filter may be made of resin such as polypropylene depending on the application.

Below theair purifier 90 and in front of the blower unit 17 is a mixing unit 95, in which the air sucked from the return air port 55 (at the second floor hall 15, the return air from the rooms and spaces and the outdoor air introduced from the outside) This is a space in which part of the mixed air) and the air blown out from the air conditioning unit 20 are mixed.
Theair blower 17 uses a fan (not shown) to blow the air blown out from the air conditioner 20 and a part of the air that bypasses the air conditioner 20 without being sucked into the air conditioner 20 from the return air port 55 . The conditioned air mixed in the mixing unit 95 is sucked from the suction port 98, further cleaned by the blower unit filter 87 (filter unit C), flowed into the air conditioned air passage A30, and the connection unit 35 It passes through and enters the air-conditioning ventilation path B31 of the inter-floor 34.
Since the plurality ofblower sections 17 are provided with the blower section filter 87 (filter section C), the air flow sucked into the blower section 17 has an appropriate resistance, and the air flow is controlled upstream of the blower section filter 87 (filter section C). In the mixing section 95, which is the space in front, the remaining part of the air blown out from the air conditioning section 20 and part of the air sucked in from the return air port 55 (suction section) stays for a while, resulting in a turbulent flow. As a result, mixing is promoted, and the air quality (temperature, humidity, cleanliness, etc.) becomes conditioned air that is uniform. The air quality becomes uniform, resulting in uniform air quality inside the building.
壁(密閉ドアを含む)と断熱材で覆われ密閉された空調ユニット10は、2階ホール15に設けられ、2階ホール15と接する密閉ドア(図示せず)の上部に、部屋A23等の空気が空調ユニット10に戻ってくる還気口55(吸込部)が設けられ、還気口フィルタ85(フィルタ部A)を備えている。
空調ユニット10の中間板21に、空調部20と送風部17は取り付けられ、その後ろには、周りを空調される部屋や空間、壁、断熱材で覆われ、気密処理が施された、気密性断熱性の高い空調送風路A30があり、送風部17の筐体の一部と吹出口22が、空調送風路A30側に出ている。
空調部20は、送風部17により還気口55から吸い込まれた空気(2階ホール15で、部屋、空間からの還気と室外から導入した室外空気が混合した空気)の一部を、送風機(図示せず)により、上面部及び前面部の吸込口96から吸い込み、空調部フィルタ86(フィルタ部B)で清浄し、熱交換器(図示せず)で、冷媒と熱交換した空気を、吹出口97より下方に吹き出す。
空調部20、還気口55と送風部17との間に、空気清浄機90が、空調ユニット10の上下を仕切るように設けられている。
空気清浄機90の下方で、送風部17の前方は、混合部95であり、還気口55から吸い込まれた空気(2階ホール15で、部屋、空間からの還気と室外から導入した室外空気が混合した空気)の一部と空調部20から吹き出された吹出空気が、混合される空間である。
送風部17は、ファン(図示せず)により、空調部20から吹き出された吹出空気と、還気口55から空調部20に吸い込まれずバイパスして流入した空気の一部を、空気清浄機90に通過させて空気清浄し、混合部95で混合した空調空気を、吸込口98から吸込み、送風部フィルタ87(フィルタ部C)でさらに清浄し、空調送風路A30に流入させ、接続部35を通って、階間34の空調送風路B31に入る。
複数の送風部17には、送風部フィルタ87(フィルタ部C)を設けているため、送風部17に吸い込まれる空気の流れにとって適当な抵抗となり、送風部フィルタ87(フィルタ部C)の上流であり、手前の空間である混合部95にて、空調部20から吹き出された吹出空気と還気口55(吸込部)から吸い込まれた空気一部の残りが、少し滞留することにより、乱流となり、混合が促進され、空気質(温湿度、清浄度等)が均一な空調空気となり、複数の送風部17に吸い込まれる空調空気や空調送風路A30、空調送風路B31を通過する空調空気の空気質が均一になり、その結果、建物内が均一な空気質になる。 FIG. 2 is a longitudinal sectional view of the

図3は、図2と同じく、空調ユニット10の縦断面図であり、送風部17に吹出ダクト36を繋げた場合である。
送風部17は、シロッコファン(図示せず)を有し、ケーシング(図示せず)の吹出口(図示せず)と吹出口22が近く、吹出口22にダクトが繋がれない開放状態の場合、設置条件によっては、吹出空気の流れが安定しない場合があるので、その場合は、吹出口22に長さ1.5m程度の吹出ダクト36を繋ぐと、一旦断面積を小さくして風速を上げることにより、流れが安定し、送風部17の性能が発揮される場合がある。
吹出ダクト36は、断熱性、耐湿性が高く、可撓性のある内径150mmのダクトで、ダクトの構成としては、外側から、順に、可撓性のある厚み0.08mm程度のポリエチレンシートなどの外部被覆材100、厚み25mmで密度24kg/m3程度のグラスウールなどの断熱材、ポリエステル不織布などに対して、非通気性、非透湿性で、表面粗さ(表面の凹凸)が小さい、厚み0.1mm程度のポリプロピレンフィルム、軟質塩化ビニルフィルム、PETフィルムなどの内部被覆材、空調空気等が通過する風路となっており、断熱材の内側と内部被覆材の間に、ポリプロピレン樹脂などの成型用芯材(図示せず)を設けて、吹出ダクト36を折り曲げても、座屈せず、内部の風路の断面積が確保できるようになっている。
吹出ダクト36の片側は、送風部17の吹出口22にそれぞれ接続され、もう一方は、階間34内の空調送風路B31の梁等に固定された隔壁37に設けられた孔部に接続し、送風部17で送風された空調空気は、空調送風路B31に入っている。隔壁37はあくまで、吹出ダクト36を固定するのが主目的であり、階間34全体に、気密性断熱性の高い空調送風路B31が設けられており、その中に隔壁37が設けられていれば、空調送風路B31の上下左右との接触面と吹出ダクト36との接触面に気密シール等を施す必要はなく、吹出ダクト36がつぶれたり、塞がれたりしなければ、隔壁37を設けず、吹出ダクト36を空調送風路B31に置くだけでもよい。
なお、この場合、吹き出しダクト36は、送風部17の性能を発揮するために繋げられただけであるので、風路として、送風部17と空調送風路B31を直接繋いだことに変わりはない。
しかし、階間34に向かって左側を空調送風路B31として使用しない場合は、隔壁37と空調送風路B31の上下左右との接触面と吹出ダクト36との接触面に気密シール等を施して、空調送風路B31の気密性を高く維持する必要がある。
吹出ダクト36の内部の清掃や交換等のメンテナンスが必要な場合は、送風部17を中間板21から外すことにより、吹出ダクト36を引っ張り出し、行えるようになっている。
本実施の形態では、吹出ダクト36を1.5m程度とし、隔壁37までとしているが、空調送風路B31の接続部35から離れた吹出口があり、途中に梁や根太等の抵抗となる構造体がある場合など、吹出口からの風量が設計風量より少なくなり、部屋間、空間間の温度が不均一になったり、部屋内、空間内の温度が不均一になる可能性がある場合は、その吹出口まで吹出ダクト36を延ばして、吹出口に直接接続することにより、それに対応した送風部17の風量をそのまま吹出口で吹き出すことも可能であるが、吹出ダクト36の内部の清掃や交換等のメンテナンスが必要な場合のために、点検口を階間34の下部である1階の天井32か、上部である2階の床33に設ける必要がある。 FIG. 3 is a vertical cross-sectional view of theair conditioning unit 10, similar to FIG.
When theair blowing unit 17 has a sirocco fan (not shown), the air outlet (not shown) of the casing (not shown) and the air outlet 22 are close to each other, and the duct is not connected to the air outlet 22 in an open state. Depending on the installation conditions, the flow of blown air may not be stable, so in that case, if a blowing duct 36 with a length of about 1.5 m is connected to the blowing port 22, the cross-sectional area will be temporarily reduced to increase the wind speed. As a result, the flow may be stabilized and the performance of the air blower 17 may be exhibited.
Theblowout duct 36 is a flexible duct with an inner diameter of 150 mm, which has high heat insulation and moisture resistance. External covering material 100, non-breathable, non-moisture permeable, small surface roughness (surface unevenness), thickness 0, heat insulating material such as glass wool with a thickness of 25 mm and a density of about 24 kg / m 3 , polyester non-woven fabric, etc. .1mm thick polypropylene film, soft vinyl chloride film, PET film, and other internal covering materials, air passages for conditioned air, etc., and molded polypropylene resin, etc. A core material (not shown) is provided so that even if the blowout duct 36 is bent, it will not buckle and the cross-sectional area of the internal air passage can be secured.
One side of the blow-outduct 36 is connected to the blow-out port 22 of the blower section 17, and the other side is connected to a hole provided in a partition wall 37 fixed to a beam or the like of the air-conditioning air-flow passage B31 in the inter-floor 34. , the air-conditioned air blown by the air blower 17 enters the air-conditioned air passage B31. The main purpose of the partition wall 37 is to fix the blow-out duct 36, and an air-conditioning air duct B31 with high airtightness and heat insulation is provided in the entire inter-floor 34, and the partition wall 37 is provided in it. For example, it is not necessary to apply an airtight seal or the like to the contact surface between the upper, lower, left, and right sides of the air conditioning air passage B31 and the contact surface with the blowout duct 36. If the blowout duct 36 is not crushed or blocked, the partition wall 37 is provided. Instead, it is sufficient to simply place the blow-out duct 36 in the air-conditioning air passage B31.
In this case, since theblowout duct 36 is connected only to exhibit the performance of the blower section 17, the blower section 17 and the air conditioning air passage B31 are directly connected as an air passage.
However, when the left side facing the inter-floor 34 is not used as the air-conditioning air duct B31, airtight sealing or the like is applied to the contact surface between thepartition wall 37 and the air-conditioning air duct B31 and the air-conditioning air duct 36. It is necessary to keep the airtightness of the air conditioning air passage B31 high.
When maintenance such as cleaning or replacement of the inside of theblowout duct 36 is required, the blowout duct 36 can be pulled out by removing the air blower 17 from the intermediate plate 21 .
In this embodiment, the blow-outduct 36 is about 1.5 m and extends to the partition wall 37, but there is a blow-out port away from the connection part 35 of the air conditioning air passage B31, and there is a structure that acts as a resistance such as a beam or a joist on the way. If there is a body, the air volume from the air outlet will be less than the designed air volume, and the temperature between rooms or spaces may become uneven, or the temperature in the room or space may become uneven. By extending the blow-out duct 36 to the blow-out port and directly connecting it to the blow-out port, it is also possible to blow out the corresponding air volume of the blower section 17 from the blow-out port as it is. For maintenance such as replacement, it is necessary to provide an inspection opening in the ceiling 32 of the first floor, which is the lower part of the inter-floor 34, or the floor 33 of the second floor, which is the upper part.
送風部17は、シロッコファン(図示せず)を有し、ケーシング(図示せず)の吹出口(図示せず)と吹出口22が近く、吹出口22にダクトが繋がれない開放状態の場合、設置条件によっては、吹出空気の流れが安定しない場合があるので、その場合は、吹出口22に長さ1.5m程度の吹出ダクト36を繋ぐと、一旦断面積を小さくして風速を上げることにより、流れが安定し、送風部17の性能が発揮される場合がある。

吹出ダクト36の片側は、送風部17の吹出口22にそれぞれ接続され、もう一方は、階間34内の空調送風路B31の梁等に固定された隔壁37に設けられた孔部に接続し、送風部17で送風された空調空気は、空調送風路B31に入っている。隔壁37はあくまで、吹出ダクト36を固定するのが主目的であり、階間34全体に、気密性断熱性の高い空調送風路B31が設けられており、その中に隔壁37が設けられていれば、空調送風路B31の上下左右との接触面と吹出ダクト36との接触面に気密シール等を施す必要はなく、吹出ダクト36がつぶれたり、塞がれたりしなければ、隔壁37を設けず、吹出ダクト36を空調送風路B31に置くだけでもよい。

空調部20の筐体の上面部と前面部の吸込口96から吸い込まれた空気は、空調部フィルタ86で空気清浄され、熱交換器91、92で冷媒と熱交換され、送風機100で、吹出口97から、ルーバー94の向いた方向に吹き出される。
空調部20は、運転モードとして、冷房/暖房/再熱除湿の3つを有し、熱交換器91、92は、各運転モードにより、流れる冷媒の特性が変わり、役割が切り替わる構造となっている。つまり、冷房運転時は、熱交換器91、92共に、低温低圧の冷媒が流れる蒸発器として機能し、暖房運転時は、熱交換器91、92共に、高温高圧の冷媒が流れる凝縮器として機能する。
そして、再熱除湿運転時は、熱交換器91が低温低圧の冷媒が流れる蒸発器として、熱交換器92が中温中圧の冷媒が流れる再熱器として機能し、熱交換器91(蒸発器)の表面温度が、吸込空気の露点温度以下の温度の冷媒の蒸発温度となるため、通過した空気は温度が下がると共に絶対湿度が下がり、熱交換器91(蒸発器)の表面に結露した凝縮水(除湿水)は、熱交換器91(蒸発器)下方のドレンパン93に流れ、ドレンホース(図示せず)で室外等へ流される。熱交換器92(再熱器)の表面温度は、吸込空気以上の温度の冷媒の凝縮温度となるため、通過した空気は温度が上がる。その2つの熱交換器91、92を通過した空気が、送風機90により、合流し、混合されて、吸込空気の温度以上で、絶対湿度の低い吹出空気となり、吹出口97から吹き出される。 FIG. 4 is a longitudinal sectional view of theair conditioning section 20. As shown in FIG.
The air sucked in from the upper andfront suction ports 96 of the housing of the air conditioning unit 20 is cleaned by the air conditioning unit filter 86, heat-exchanged with the refrigerant by the heat exchangers 91 and 92, and blown by the blower 100. The air is blown out from the outlet 97 in the direction in which the louver 94 faces.
Theair conditioning unit 20 has three operation modes of cooling/heating/reheat dehumidification, and the heat exchangers 91 and 92 have a structure in which the characteristics of the flowing refrigerant change depending on each operation mode, and the roles are switched. there is That is, during cooling operation, both the heat exchangers 91 and 92 function as evaporators through which low-temperature, low-pressure refrigerant flows, and during heating operation, both the heat exchangers 91 and 92 function as condensers through which high-temperature, high-pressure refrigerant flows. do.
During the reheat dehumidification operation, theheat exchanger 91 functions as an evaporator through which a low-temperature, low-pressure refrigerant flows, and the heat exchanger 92 functions as a reheater through which a medium-temperature, medium-pressure refrigerant flows. ) becomes the evaporation temperature of the refrigerant whose temperature is lower than the dew point temperature of the intake air, the temperature of the passing air decreases and the absolute humidity decreases, and the condensation formed on the surface of the heat exchanger 91 (evaporator) Water (dehumidified water) flows into a drain pan 93 below the heat exchanger 91 (evaporator), and is discharged outdoors or the like through a drain hose (not shown). Since the surface temperature of the heat exchanger 92 (reheater) is the condensation temperature of the refrigerant having a temperature higher than that of the intake air, the temperature of the passing air rises. The air that has passed through the two heat exchangers 91 and 92 joins and is mixed by the blower 90 to become blowing air having a temperature higher than that of the intake air and a low absolute humidity, and is blown out from the blowing port 97. - 特許庁

ここで、建物2は高気密高断熱で、還気路での温度勾配がほとんどないため、空調部20の吸込空気の温度は、2階ホール15の温度や各部屋、各空間からの戻り空気の平均温度や各部屋、各空間の平均温度とほぼ同じとなる。
空調送風路A30は、接続部35で、空調送風路B31と繋がり、いずれも建物2の外皮から遠く、周囲を部屋や空間や壁、断熱材に囲まれ、気密処理も施されているので、空調送風路内の空調空気の温度勾配は、ほとんど生じない。
空調送風路A30、空調送風路B31の内側の表面は、下地板、梁、根太等となるが、それらにもともと付着している微細な埃等が、通過する空調空気により、一緒に部屋や空間に搬送されないよう、それらの表面に、非通気性、非透湿性で、表面粗さ(表面の凹凸)が小さい、厚み0.1mm程度のポリプロピレンフィルム、軟質塩化ビニルフィルム、PETフィルムなどの内部被覆材を、気密シートと兼ねて、もしくは単独で、貼り付けてもよい。もっとも、貼り付けなくても、暫く連続して空調空気を流せば、複数のフィルタ部や空気清浄機90により清浄され、熱交換気ユニット60の排気ファンや天井埋込型換気扇81により室外に排出され、その後、建物2内は清浄された空調空気が循環するようになる。 Here, thebuilding 2 is highly airtight and highly insulated, and there is almost no temperature gradient in the return air path. It is almost the same as the average temperature of each room and the average temperature of each space.
The air-conditioning air duct A30 is connected to the air-conditioning air duct B31 at theconnection part 35, and both are far from the outer skin of the building 2, and are surrounded by rooms, spaces, walls, and heat insulating materials, and are also airtightly treated. A temperature gradient of the conditioned air in the conditioned air duct is almost non-existent.
The inner surfaces of the air-conditioning air duct A30 and the air-conditioning air duct B31 are substrate boards, beams, joists, etc., and fine dust and the like originally adhered to them are mixed with the room or space by the air-conditioned air passing through. 0.1 mm thick polypropylene film, soft vinyl chloride film, PET film, or other internal coating that is non-breathable, non-moisture permeable, and has small surface roughness (surface irregularities) so that it will not be transported to The material may also serve as an airtight sheet or may be attached alone. However, even if the conditioned air is not attached, if the conditioned air is allowed to flow continuously for a while, it will be cleaned by the plurality of filter units and theair purifier 90, and will be discharged to the outside by the exhaust fan of the heat exchange air unit 60 and the ceiling-mounted ventilation fan 81. After that, the cleaned conditioned air circulates in the building 2.
空調送風路A30は、接続部35で、空調送風路B31と繋がり、いずれも建物2の外皮から遠く、周囲を部屋や空間や壁、断熱材に囲まれ、気密処理も施されているので、空調送風路内の空調空気の温度勾配は、ほとんど生じない。

The inner surfaces of the air-conditioning air duct A30 and the air-conditioning air duct B31 are substrate boards, beams, joists, etc., and fine dust and the like originally adhered to them are mixed with the room or space by the air-conditioned air passing through. 0.1 mm thick polypropylene film, soft vinyl chloride film, PET film, or other internal coating that is non-breathable, non-moisture permeable, and has small surface roughness (surface irregularities) so that it will not be transported to The material may also serve as an airtight sheet or may be attached alone.

空調送風路B31を通過した空調空気は、玄関13の吹出口42から吹き出し、また、風量を100m3/h~200m3/hに調整可能な送風ファン45、46のモーターを運転させ、ファンに吸い込まれた空調空気を部屋A23の吹出口40と部屋B24の吹出口41から吹き出して、玄関13、部屋A23、部屋B24を空調換気する。
つまり、空調ユニット10内で生成された約1500m3/hの、各部屋、各空間の温度に対し、冷房時約5K、暖房時約10K以内で、複数のフィルタ部と空気清浄機90で空気清浄された空調空気が、送風部17により、周囲を部屋、空間等に囲まれた空調送風路A30、空調送風路B31内を通って、吹出口40、41、42から、部屋A23、部屋B24、玄関13に吹き出されるので、空調空気は、空調送風路A30、空調送風路B31を通過しても、ほとんど温度勾配がなく、そのまま、各部屋、各空間の温度に対し、冷房時約5K、暖房時約10K以内の大風量の清浄された空調空気が、吹出口40、41、42から吹き出し、建物2内が非常に快適で均一な温度で、非常に良い空気質に空調換気される。
また、空調送風路A30、空調送風路B31内には、上記のように、空調送風路の周囲の部屋、空間の温度に対し、冷房時約5K、暖房時約10K以内の大風量の清浄された空調空気が、通過するので、空調送風路内外で結露することもなく、特に、空調送風路内に、水分や埃や菌などが滞留、堆積しにくい。
吹出口40、41に送風ファンを設けたのは、吹出口42より空調送風路B31の接続部35から離れた吹出口であり、途中に梁や根太等の抵抗となる構造体がある場合や、部屋A23、部屋B24の排気口50、51の開口面積が小さい場合など、吹出口40、41からの風量が設計風量より少なくなる可能性があり、部屋間、空間間の温度が不均一になったり、部屋内、空間内の温度が不均一になる可能性があるためである。
また、空調送風路B31の断面積が大きく、空調送風路B31内の風速が小さい場合、空調空気の比重が影響し、暖房時は比重が軽く、2階の床の吹出口からの風量が多くなり、2階が十分温まるが、1階の天井の吹出口からの風量は少なくなり、1階は寒く、逆に、冷房時は比重が重いので、1階が十分涼しいが、2階は暑い可能性があるためでもあり、建物2や空調換気システム1により、同様な問題が発生する可能性がある吹出口に設ければよく、設置に関しては、送風ファンの運転により騒音や消費電力が増加することを考慮しなければならない。
また、吹出口40、41、42、送風ファン45、46の定期的な清掃などのメンテナンスや長期使用時の交換等が可能なように、部屋A23、部屋B24、玄関13から、それらを取り外せる構造とするか、近くに点検口を設ける必要がある。 The air-conditioned air that has passed through the air-conditioned air passage B31 is blown out from theair outlet 42 of the entrance 13, and the motors of the air blowers 45 and 46 that can adjust the air volume to 100 m 3 /h to 200 m 3 /h are operated. The sucked conditioned air is blown out from the outlet 40 of the room A23 and the outlet 41 of the room B24 to air-condition and ventilate the entrance 13, the room A23 and the room B24.
In other words, for the temperature of each room and each space of about 1500 m 3 /h generated in theair conditioning unit 10, the air is cooled by the plurality of filter units and the air cleaner 90 within about 5 K during cooling and within about 10 K during heating. Cleaned air-conditioning air is passed through the air-conditioning air passage A30 and the air-conditioning air passage B31 surrounded by rooms, spaces, etc. by the air blower 17, and from the outlets 40, 41, 42, into the room A23 and the room B24. Since the conditioned air is blown out to the entrance 13, even if it passes through the conditioned air passages A30 and B31, there is almost no temperature gradient. , Cleaned conditioned air with a large air volume of about 10K or less during heating is blown out from the outlets 40, 41, 42, and the inside of the building 2 is air-conditioned and ventilated with a very comfortable and uniform temperature and very good air quality. .
In addition, in the air-conditioning air passage A30 and the air-conditioning air passage B31, as described above, there is a large amount of clean air of about 5K during cooling and about 10K during heating with respect to the temperature of the room and space around the air-conditioning air passage. Since the air-conditioned air passes through, condensation does not occur inside and outside the air-conditioning air passage, and especially moisture, dust, bacteria, etc. are less likely to stay and accumulate in the air-conditioning air passage.
The air outlets 40 and 41 are provided with blower fans because they are farther from the connection part 35 of the air conditioning air passage B31 than the air outlet 42. , Room A23 and Room B24, the air volume from the air outlets 40 and 41 may be less than the designed air volume, such as when the opening area of the air outlets 50 and 51 is small, and the temperature between the rooms and spaces may become uneven. This is because there is a possibility that the temperature in the room or space may become uneven.
In addition, when the cross-sectional area of the air-conditioning air passage B31 is large and the wind speed in the air-conditioning air passage B31 is small, the specific gravity of the air-conditioned air is affected. The 2nd floor is warm enough, but the air volume from the air outlet on the ceiling of the 1st floor is small, and the 1st floor is cold. This is also because there is a possibility that the same problem may occur depending on thebuilding 2 or the air conditioning ventilation system 1, so it should be installed at the outlet where the same problem may occur. must consider doing.
In addition, the outlets 40, 41, 42 and the fans 45, 46 can be removed from the room A23, the room B24, and the entrance 13 so that maintenance such as periodic cleaning and replacement for long-term use are possible. Alternatively, it is necessary to provide an inspection opening nearby.
つまり、空調ユニット10内で生成された約1500m3/hの、各部屋、各空間の温度に対し、冷房時約5K、暖房時約10K以内で、複数のフィルタ部と空気清浄機90で空気清浄された空調空気が、送風部17により、周囲を部屋、空間等に囲まれた空調送風路A30、空調送風路B31内を通って、吹出口40、41、42から、部屋A23、部屋B24、玄関13に吹き出されるので、空調空気は、空調送風路A30、空調送風路B31を通過しても、ほとんど温度勾配がなく、そのまま、各部屋、各空間の温度に対し、冷房時約5K、暖房時約10K以内の大風量の清浄された空調空気が、吹出口40、41、42から吹き出し、建物2内が非常に快適で均一な温度で、非常に良い空気質に空調換気される。

吹出口40、41に送風ファンを設けたのは、吹出口42より空調送風路B31の接続部35から離れた吹出口であり、途中に梁や根太等の抵抗となる構造体がある場合や、部屋A23、部屋B24の排気口50、51の開口面積が小さい場合など、吹出口40、41からの風量が設計風量より少なくなる可能性があり、部屋間、空間間の温度が不均一になったり、部屋内、空間内の温度が不均一になる可能性があるためである。

The air sucked from the return air port 55 (air mixed with the return air from the rooms and spaces and the outdoor air introduced from the outside in thehall 15 on the second floor) is again conditioned by the air conditioning unit 10, and each room Since the heat is supplied to each space, the heat and air quality of the return air are reused, resulting in energy saving.
A part of the air in which the return air from the room or space and the outdoor air introduced from the outside are mixed flows into thetoilet 61 from the louver 75 of the toilet 61 by the heat exchange air unit 60, and the moisture in the toilet 61, The air containing odors, harmful substances, etc. is completely heat-exchanged by the heat exchange air unit 60 with the outdoor air cleaned by the filter box 70, exhausted to the outside from the outdoor exhaust hood A66, and returned air from the room and space.

When a large amount of moisture or a strong odor is temporarily generated in thebathroom 80, such as when taking a bath, the ceiling-mounted ventilation fan 81 is operated at a high notch to quickly discharge the air directly to the outside while the thunder 76 is removed. Therefore, part of the air mixed with the return air from the room or space and the outdoor air introduced from the outside replaces the air in the bathroom 80. Therefore, when stable, the air quality (temperature and humidity) in the bathroom 80 is close to that of conditioned air , cleanliness, etc.).

各送風部17の各送風量は、各部屋、各空間の容積から決定する。空調のために必要な送風量は、部屋2.5m3当たり少なくとも8m3/h以上、理想的には20m3/h以上が望ましく、部屋の大きさや日射などの空調負荷によって送風量を調整する。送風部17は、高効率なDCモーター(図示せず)でシロッコファン(図示せず)を回転させるので、空調負荷等によって、シロッコファン(図示せず)の回転数を制御部140、モーター制御部141で制御する。
送風部17の台数は、基本的に、吹出口1台につき1台とするが、前述した必要送風量に対し、送風部17に余裕がある場合、部屋や空間の形状により、吹出口を増やすことも可能であるが、空調送風路内の抵抗により風量分配が変わり、風速がダウンすること等により、途中の空調送風路に、水分、埃、菌等が滞留、堆積する可能性があり、また清掃等のメンテナンスも困難となるので、原則として、1:1とするのが望ましく、どうしても複数の吹出口を設ける場合は、吹出口に送風ファンを設ける又は、後から分岐部内の清掃や交換が可能なように、近くに点検口を設ける必要がある。 The amount of air blown by eachair blower 17 is determined from the volume of each room and each space. Airflow required for air conditioning is at least 8m 3 /h or more per 2.5m 3 room, ideally 20m 3 /h or more. . Since the blower unit 17 rotates a sirocco fan (not shown) with a highly efficient DC motor (not shown), the rotation speed of the sirocco fan (not shown) is controlled by the control unit 140 and the motor control unit 140 depending on the air conditioning load and the like. It is controlled by the unit 141 .
Basically, the number ofair blowing units 17 is one for each air outlet, but if the air blowing unit 17 has a margin for the required air blow amount described above, the number of air outlets may be increased depending on the shape of the room or space. Although it is possible to do so, there is a possibility that moisture, dust, bacteria, etc. will accumulate and accumulate in the air-conditioning air duct along the way due to changes in air volume distribution due to resistance in the air-conditioning air duct and reduction in wind speed. Also, maintenance such as cleaning is difficult, so in principle, it is desirable to have a ratio of 1:1. If multiple outlets are to be provided, a blower fan should be installed at the outlet, or the inside of the branch may be cleaned or replaced later. It is necessary to provide an inspection door nearby so that
送風部17の台数は、基本的に、吹出口1台につき1台とするが、前述した必要送風量に対し、送風部17に余裕がある場合、部屋や空間の形状により、吹出口を増やすことも可能であるが、空調送風路内の抵抗により風量分配が変わり、風速がダウンすること等により、途中の空調送風路に、水分、埃、菌等が滞留、堆積する可能性があり、また清掃等のメンテナンスも困難となるので、原則として、1:1とするのが望ましく、どうしても複数の吹出口を設ける場合は、吹出口に送風ファンを設ける又は、後から分岐部内の清掃や交換が可能なように、近くに点検口を設ける必要がある。 The amount of air blown by each
Basically, the number of
空調部20は建物2の空調負荷により、能力、台数を選定するが、能力選定にあたっては、よりCOPが高い低周波数(30Hz前後)での圧縮機(図示せず)運転が継続する能力(建物の空調負荷に対し、適正な定格能力、多くて100%)のエアコン等を選定すると、安定時に低周波数での継続運転となり、より省エネで、ハンチングのない安定した温湿度となるので、望ましい。
空調ユニット10で、還気口55から吸い込まれた空気(2階ホール15で、部屋、空間からの還気と室外から導入した室外空気が混合した空気)と空調部20で空調された吹出空気とを確実に混合させ、各部屋、各空間の温度差の少ない均一な温度、つまり、各部屋、各空間の目標温度に対し、冷房時5K以内、暖房時10K以内の温度差の空調空気となるように、空調部20の風量は、複数の送風部17の合計送風量の50%以下の風量とするのが望ましい。
その空調空気を複数の送風部17で、空調送風路を通して、各部屋、各空間の天井や床に設けられた吹出口から送風することにより、各部屋、各空間を均一な快適な温度に空調換気する。
例えば、建物の床面積が約100m2、天井高さは2.5mの場合、4kW相当の冷房能力をもつ空調部20を設置し、弱風モードでは冷房運転時空調風量は600m3/hとなる。各部屋、各空間に送風する送風部17は、1台あたりの送風量が、弱風量で100m3/h程度、中風量で150m3/h程度、強風量で200m3/hのものを設定し、10台の送風部17の場合の合計送風量は1000m3/h~2000m3/h程度になり、空調部20の空調風量よりも多く、合計送風量の30~60%の風量が空調部20の空調風量(弱風モード)として設定する。
なお、空調風量とは、空調部20の熱交換器(図示せず)を通過する風量であり、大風量で各部屋に空調空気を吹出せるように、熱交換器通過による圧力損失を避けるため、熱交換器をバイパスする風路を有する空調部20の場合は、バイパス風路の風量は空調風量から除くものとする。 Theair conditioning unit 20 selects the capacity and the number of units depending on the air conditioning load of the building 2. In selecting the capacity, the capacity (building It is desirable to select an air conditioner with an appropriate rated capacity (100% at most) for the air conditioning load, because it will continue to operate at a low frequency when stable, resulting in more energy saving and stable temperature and humidity without hunting.
Air sucked from thereturn air port 55 in the air conditioning unit 10 (air mixed with the outdoor air introduced from the outside and the return air from the rooms and spaces in the hall 15 on the second floor) and the blown air conditioned by the air conditioning unit 20 and ensure a uniform temperature with little temperature difference between each room and each space. Therefore, it is desirable that the air volume of the air conditioning unit 20 is 50% or less of the total air volume of the plurality of air blowing units 17 .
By blowing the conditioned air from air outlets provided on the ceiling and floor of each room and each space through air-conditioning air ducts with a plurality ofair blowing units 17, each room and each space is air-conditioned to a uniform and comfortable temperature. Ventilate.
For example, if the building has a floor area of about 100 m 2 and a ceiling height of 2.5 m, theair conditioning unit 20 with a cooling capacity equivalent to 4 kW is installed, and in the weak wind mode, the air conditioning air volume during cooling operation is 600 m 3 /h. Become. The blower unit 17 that blows air to each room and each space has a blowing volume of about 100 m 3 /h for a weak air volume, about 150 m 3 /h for a medium air volume, and 200 m 3 /h for a strong air volume. However, in the case of ten air blowing units 17, the total air blowing volume is about 1000 m 3 /h to 2000 m 3 /h, which is larger than the air conditioning air volume of the air conditioning unit 20, and 30 to 60% of the total air blowing volume is used for air conditioning. It is set as the air conditioning air volume (weak air mode) of the unit 20 .
The conditioned air volume is the volume of air that passes through the heat exchanger (not shown) of theair conditioning unit 20. In order to blow conditioned air into each room with a large air volume, pressure loss due to passage through the heat exchanger is avoided. In the case of the air conditioning unit 20 having an air passage bypassing the heat exchanger, the air volume of the bypass air passage shall be excluded from the air conditioning air volume.
空調ユニット10で、還気口55から吸い込まれた空気(2階ホール15で、部屋、空間からの還気と室外から導入した室外空気が混合した空気)と空調部20で空調された吹出空気とを確実に混合させ、各部屋、各空間の温度差の少ない均一な温度、つまり、各部屋、各空間の目標温度に対し、冷房時5K以内、暖房時10K以内の温度差の空調空気となるように、空調部20の風量は、複数の送風部17の合計送風量の50%以下の風量とするのが望ましい。
その空調空気を複数の送風部17で、空調送風路を通して、各部屋、各空間の天井や床に設けられた吹出口から送風することにより、各部屋、各空間を均一な快適な温度に空調換気する。
例えば、建物の床面積が約100m2、天井高さは2.5mの場合、4kW相当の冷房能力をもつ空調部20を設置し、弱風モードでは冷房運転時空調風量は600m3/hとなる。各部屋、各空間に送風する送風部17は、1台あたりの送風量が、弱風量で100m3/h程度、中風量で150m3/h程度、強風量で200m3/hのものを設定し、10台の送風部17の場合の合計送風量は1000m3/h~2000m3/h程度になり、空調部20の空調風量よりも多く、合計送風量の30~60%の風量が空調部20の空調風量(弱風モード)として設定する。
なお、空調風量とは、空調部20の熱交換器(図示せず)を通過する風量であり、大風量で各部屋に空調空気を吹出せるように、熱交換器通過による圧力損失を避けるため、熱交換器をバイパスする風路を有する空調部20の場合は、バイパス風路の風量は空調風量から除くものとする。 The

熱交換気ユニット60で導入する室外空気導入量、室内空気排出量、いわゆる換気風量としては、床面積約100m2、天井高さ2.5mの換気回数0.5回/hの場合、24時間換気風量125m3/hとする。
浴室80で、入浴中などでは、天井埋込型換気扇81の排気風量が80m3/h程度増えるため、一時的に排気過多となるが、短時間であり、その負圧により熱交換気ユニット60の室外空気導入量が少し増えるため、建物2全体として、適正量の新鮮で空気清浄された室外空気を導入しながら、水分や二酸化炭素、臭気、VOC、埃、菌他を排出でき、省エネで健康快適な空調換気を実現できる。 The amount of outdoor air introduced by the heatexchange air unit 60, the amount of indoor air discharged, the so-called ventilation air amount, is 24 hours in the case of a floor area of about 100 m 2 and a ceiling height of 2.5 m with a ventilation rate of 0.5 times/h. The ventilation air volume is 125 m 3 /h.
In thebathroom 80, during bathing, etc., the exhaust air volume of the ceiling-mounted ventilation fan 81 increases by about 80 m 3 /h. Since the amount of outdoor air introduced in the building 2 is slightly increased, while introducing an appropriate amount of fresh and air-purified outdoor air to the building 2 as a whole, moisture, carbon dioxide, odors, VOCs, dust, bacteria, etc. can be discharged, saving energy. A healthy and comfortable air-conditioning ventilation can be achieved.

夏季、室温設定温度25℃では、冷房運転の空調部20の吹出温度は、還気口55から吸い込まれる空気の温度26℃に対し約10K以上低い、15℃であるが、26℃の還気口55から吸い込まれる空気と混合して、還気口55から吸い込まれる空気の温度に対し、約5K低い21℃となり、送風部17に吸い込まれ、空調送風路を通っているため、温度勾配がなく、21℃で、吹出口から各部屋、各空間に吹き出す。安定時、空調送風路の周囲は空調換気された部屋、空間であり、空調送風路の内周表面温度は21℃に近い22℃となり、外周表面温度は、周囲の部屋、空間の室温25℃に近い24℃となる。
部屋、空間の室温25℃相対湿度60%の場合、露点温度は17℃であり、空調送風路の外周表面には、結露しない。
また、室外温度が下がり、空調負荷が減って、空調部20がサーモOFFして、圧縮機が停止した場合、空調部20の吹出空気の温湿度は、温度は室温と同じく25℃で、相対湿度は、空調部20の蒸発器に結露した凝縮水が再蒸発して、少し高く80%となっても、露点温度は21℃であり、空調送風路の内周表面にも、結露しない。
比較として、従来のダクト式空調換気システムでは、空調部が吹き出した空気をそのままダクトに流すので、空調部の吸込空気の温度26℃に対し約10K以上低い15℃の吹出空気が流れて、ダクトの内周表面を冷やし、17℃程度になる。この状態で、サーモOFFし、圧縮機が停止すると、吹出空気は温度25℃相対湿度80%露点温度21℃となり、ダクト内を通過すると、ダクト内周表面に結露する。 In summer, when the room temperature is set at 25°C, the blowout temperature of theair conditioning unit 20 in the cooling operation is about 10K or more lower than the temperature of the air sucked from the return air port 55, which is 26°C. It mixes with the air sucked from the port 55 and reaches 21° C., which is about 5K lower than the temperature of the air sucked from the return air port 55. Since it is sucked into the air blower 17 and passes through the air conditioning air passage, there is a temperature gradient. Instead, the air is blown out from the outlet into each room and space at 21°C. At the time of stability, the surroundings of the air conditioning duct are air-conditioned and ventilated rooms and spaces. 24°C, which is close to
When the room temperature is 25° C. and the relative humidity is 60%, the dew point temperature is 17° C., and no condensation occurs on the outer peripheral surface of the air-conditioning air duct.
When the outdoor temperature drops, the air conditioning load decreases, the thermostat is turned off, and the compressor stops, the temperature and humidity of the air blown out from theair conditioning unit 20 is 25° C., which is the same as the room temperature. Even if the humidity is a little higher at 80% due to re-evaporation of the condensed water on the evaporator of the air conditioner 20, the dew point temperature is 21° C., and no condensation occurs on the inner peripheral surface of the air conditioning air duct.
As a comparison, in the conventional duct type air-conditioning and ventilation system, the air blown out from the air-conditioning unit flows through the duct as it is. The inner peripheral surface of is cooled to about 17°C. In this state, when the thermostat is turned off and the compressor stops, the blown air has a temperature of 25° C. and a relative humidity of 80% and a dew point of 21° C. After passing through the duct, condensation forms on the inner peripheral surface of the duct.

冬季、室温設定温度21℃では、暖房運転の空調部20の吹出温度は、還気口55から吸い込まれる空気の温度20℃に対し約20K以上高い、42℃であるが、19℃の還気口55から吸い込まれる空気と混合して、還気口55から吸い込まれる空気の温度に対し約10K高い30℃となり、送風部17により、空調送風路を通っているため、温度勾配がなく、30℃で、吹出口から各部屋、各空間に吹き出す。安定時、空調送風路の周囲は空調換気された部屋、空間であり、空調送風路の内周表面温度は30℃に近い28℃となり、外周表面温度は、周囲の部屋、空間の室温21℃に近い23℃となる。
送風部17の吹出空気の温湿度は、温度30℃相対湿度32%露点温度12℃であり、空調送風路の内周表面に結露しない。加湿器により加湿して相対湿度が50%に上がっても、露点温度は18℃のため、結露しない。
また、室外温度が上がり、空調負荷が減って、空調部20がサーモOFFして、圧縮機が停止した場合、送風部17の吹出空気の温湿度は、温度は室温と同じく21℃で、相対湿度は高くなり60%となり、露点温度は12℃であり、空調送風路の内周表面に、結露しない。加湿器により加湿して相対湿度が80%まで上がっても、露点温度は17℃で、結露しない。
比較として、従来のダクト式空調換気システムでは、ダクトが住宅内の断熱空間を通らず、その空間が空調もされておらず、ダクトの断熱性能も低い場合、その空間の温度は外気温に近く、例えば外気温0℃、空間温度2℃となっている状態で、空調部が吹き出した空気をそのままダクトに流すので、空調部の吸込空気の温度20℃に対し約20K以上高い40℃の吹出空気が流れて、相対湿度20%では、露点温度13℃となり、ダクト内表面温度が13℃以下となった場合、ダクト内周表面に結露する。この状態で、サーモOFFし、圧縮機が停止すると、吹出空気は温度21℃相対湿度60%露点温度13℃となり、同様に結露する。

Even if it is humidified by a humidifier and the relative humidity rises to 50%, the dew point temperature is 18° C., so no condensation occurs.
In addition, when the outdoor temperature rises, the air conditioning load decreases, theair conditioning unit 20 turns off the thermostat, and the compressor stops, the temperature and humidity of the air blown from the blower unit 17 is 21° C., which is the same as the room temperature. The humidity rises to 60%, the dew point temperature is 12° C., and no condensation occurs on the inner peripheral surface of the air-conditioning air duct. Even when humidified by a humidifier and the relative humidity rises to 80%, the dew point temperature is 17°C and no condensation occurs.
By comparison, in a conventional ducted air-conditioning and ventilation system, if the duct does not pass through an insulated space inside the house, the space is not air-conditioned, and the duct has poor insulation performance, the temperature in that space will be close to the outside air temperature. For example, in a state where the outside temperature is 0°C and the space temperature is 2°C, the air blown out by the air conditioning unit is flowed through the duct as it is, so the air temperature is 40°C, which is about 20K higher than the intake air temperature of the air conditioning unit. When the air flows and the relative humidity is 20%, the dew point temperature becomes 13° C., and when the inner surface temperature of the duct becomes 13° C. or less, dew condensation occurs on the inner peripheral surface of the duct. In this state, when the thermostat is turned off and the compressor stops, the blown air has a temperature of 21° C. and a relative humidity of 60% and a dew point temperature of 13° C., and condensation occurs in the same manner.

By comparison, in a conventional ducted air-conditioning and ventilation system, if the duct does not pass through an insulated space inside the house, the space is not air-conditioned, and the duct has poor insulation performance, the temperature in that space will be close to the outside air temperature. For example, in a state where the outside temperature is 0°C and the space temperature is 2°C, the air blown out by the air conditioning unit is flowed through the duct as it is, so the air temperature is 40°C, which is about 20K higher than the intake air temperature of the air conditioning unit. When the air flows and the relative humidity is 20%, the dew point temperature becomes 13° C., and when the inner surface temperature of the duct becomes 13° C. or less, dew condensation occurs on the inner peripheral surface of the duct. In this state, when the thermostat is turned off and the compressor stops, the blown air has a temperature of 21° C. and a relative humidity of 60% and a dew point temperature of 13° C., and condensation occurs in the same manner.
Humidification by a humidifier increases the relative humidity, which further increases the amount of condensation.
空調部20の風量600m3/hより、複数の送風部17の合計風量1500m3/hが大幅に多く、約1500m3/hの、各部屋、各空間の温度に対し、冷房時約5K、暖房時約10K以内の空調空気が、部屋、空間に吹き出されるので、長時間、部屋、空間の温度は安定する。また、空調部20の能力決定にあたっては、よりCOPが高い低周波数での圧縮機(図示せず)運転が継続する能力(建物の空調負荷に対し、適正な定格能力、多くて100%)のエアコン等を選定する。よって、省エネのため、安定時には、圧縮機(図示せず)が低周波数で長時間運転するよう、空調部20の設定温度は、部屋、空間の平均温度より、少し低く(冷房時約5K以内)、少し高く(暖房時約10K以内)設定する。高気密高断熱住宅のため、部屋、空間の平均温度と還気口55(吸込部)から吸い込まれる空気の温度と空調部20の吸込空気の温度は、ほぼ等しいため、長時間継続して、空調部20の吸込空気の温度が、設定温度より少し高い(冷房時)、少し低い(暖房時)ことにより、サーモON状態で、圧縮機が低周波数で運転するので、サーモON/OFF等による温湿度のハンチングや、圧縮機立ち上がり時のCOPが低い状態が発生せず、建物2内全体が、省エネで、快適で均一な温湿度となる。
The total air volume of 1500 m 3 /h of the plurality of air blowing units 17 is significantly larger than the air volume of 600 m 3 / h of the air conditioning unit 20, and the temperature of each room and space of about 1500 m 3 /h Since conditioned air within about 10K during heating is blown into the room and space, the temperature of the room and space is stable for a long time. Also, in determining the capacity of the air conditioning unit 20, the ability to continue the operation of the compressor (not shown) at a low frequency with a higher COP (appropriate rated capacity for the air conditioning load of the building, at most 100%). Select an air conditioner, etc. Therefore, in order to save energy, the set temperature of the air conditioning unit 20 is slightly lower than the average temperature of the room and space (within about 5 K during cooling) so that the compressor (not shown) operates at a low frequency for a long time when stable. ), set a little higher (within about 10K during heating). Since the house is highly airtight and highly insulated, the average temperature of the rooms and spaces, the temperature of the air sucked from the return air port 55 (suction part), and the temperature of the air sucked into the air conditioning part 20 are almost the same. When the temperature of the intake air of the air conditioning unit 20 is slightly higher (during cooling) or slightly lower (during heating) than the set temperature, the compressor operates at a low frequency with the thermo ON state. Hunting of temperature and humidity and a state where the COP is low when the compressor starts up do not occur, and the entire inside of the building 2 is energy-saving, comfortable and uniform in temperature and humidity.
特に夏季の冷房運転時は、空調部20は、小温度差でのサーモON状態が長時間継続し、圧縮機(図示せず)が継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下する。
例えば、夏季の室外温度約35℃相対湿度約40%の冷房運転時、室温設定温度25℃の安定時では、部屋、空間の平均温度25℃に対し、還気路での温度勾配と、室内空気と熱交換した30℃程度の室外空気と合流することにより、空調ユニット10の吸込空気温度は約26℃となり、空調部20の設定温度を、吸込空気温度26℃に対し約2~4K低い、22~24℃とすると、空調部20は、小温度差でのサーモON状態が長時間継続し、圧縮機(図示せず)が低周波数で継続して運転し、除去される除湿量も多くなり、絶対湿度の低い空調空気が流れる空調送風路内、部屋、空間の相対湿度も40%以下に低下する。
なお、通常、エアコンの冷房運転時において、サーモON時に蒸発器に結露した凝縮水は、サーモOFF時に圧縮機が停止し、蒸発温度が上がると、凝縮水が吸込空気により、再蒸発して、吹出空気の絶対湿度が上昇し、非常に不快な高い絶対湿度の空気となるが、本空調換気システム1では、サーモOFFの頻度が減り、そういった空調空気とはなりにくい。 Especially during cooling operation in summer, theair conditioning unit 20 continues for a long time in the thermo ON state with a small temperature difference, and the compressor (not shown) continues to operate, so the surface temperature of the evaporator, the so-called evaporation When the temperature drops below the dew point temperature of the intake air, the moisture in the intake air condenses on the evaporator, and the amount of dehumidification removed increases with long-term operation, and the absolute humidity of the blown air decreases continuously for a long period of time. However, the absolute humidity of the conditioned air also decreases, and the relative humidity of the air-conditioned air passage, room, and space in which the conditioned air flows also decreases.
For example, during cooling operation in the summer with an outdoor temperature of about 35°C and a relative humidity of about 40%, when the room temperature setting is stable at 25°C, the average temperature of the room and space is 25°C. By merging with the outdoor air of about 30°C that has exchanged heat with the air, the intake air temperature of theair conditioning unit 10 becomes about 26°C, and the set temperature of the air conditioning unit 20 is about 2 to 4K lower than the intake air temperature of 26°C. , 22° C. to 24° C., the air conditioning unit 20 continues the thermo ON state with a small temperature difference for a long time, the compressor (not shown) continues to operate at a low frequency, and the amount of dehumidification removed is also The relative humidity in the air-conditioning air passages, rooms, and spaces through which the air-conditioning air with low absolute humidity flows is reduced to 40% or less.
Normally, during the cooling operation of the air conditioner, the condensed water condensed on the evaporator when the thermostat is ON is re-evaporated by the intake air when the compressor stops when the thermostat is OFF and the evaporation temperature rises. The absolute humidity of the blown air rises and becomes very uncomfortable high absolute humidity air. However, in the present air conditioning ventilation system 1, the frequency of turning off the thermostat is reduced, and such conditioned air is unlikely to occur.
例えば、夏季の室外温度約35℃相対湿度約40%の冷房運転時、室温設定温度25℃の安定時では、部屋、空間の平均温度25℃に対し、還気路での温度勾配と、室内空気と熱交換した30℃程度の室外空気と合流することにより、空調ユニット10の吸込空気温度は約26℃となり、空調部20の設定温度を、吸込空気温度26℃に対し約2~4K低い、22~24℃とすると、空調部20は、小温度差でのサーモON状態が長時間継続し、圧縮機(図示せず)が低周波数で継続して運転し、除去される除湿量も多くなり、絶対湿度の低い空調空気が流れる空調送風路内、部屋、空間の相対湿度も40%以下に低下する。
なお、通常、エアコンの冷房運転時において、サーモON時に蒸発器に結露した凝縮水は、サーモOFF時に圧縮機が停止し、蒸発温度が上がると、凝縮水が吸込空気により、再蒸発して、吹出空気の絶対湿度が上昇し、非常に不快な高い絶対湿度の空気となるが、本空調換気システム1では、サーモOFFの頻度が減り、そういった空調空気とはなりにくい。 Especially during cooling operation in summer, the
For example, during cooling operation in the summer with an outdoor temperature of about 35°C and a relative humidity of about 40%, when the room temperature setting is stable at 25°C, the average temperature of the room and space is 25°C. By merging with the outdoor air of about 30°C that has exchanged heat with the air, the intake air temperature of the
Normally, during the cooling operation of the air conditioner, the condensed water condensed on the evaporator when the thermostat is ON is re-evaporated by the intake air when the compressor stops when the thermostat is OFF and the evaporation temperature rises. The absolute humidity of the blown air rises and becomes very uncomfortable high absolute humidity air. However, in the present air conditioning ventilation system 1, the frequency of turning off the thermostat is reduced, and such conditioned air is unlikely to occur.
上記のような、空調部20の能力決定を行っても、室外温度による空調負荷の変化、例えば、梅雨時期のそれほど温度は高くないが、蒸し蒸しとした高湿度の時(温度27℃、相対湿度80%以上)などでは、空調部20を冷房運転した場合、一般的なエアコンなど顕熱能力が高いため、比較的早く温度だけ下がってサーモOFFしてしまい、除去される除湿量が少なく、吹出空気の絶対湿度が下がらず、空調空気の絶対湿度も下がらず、空調空気が流れる空調送風路内、部屋、空間の相対湿度も下がらず、温度だけが下がって、逆に相対湿度が上がってしまう場合がある。
このような場合は、空調部20の運転モードを再熱除湿運転とし、熱交換器91が低温低圧の冷媒が流れる蒸発器として、熱交換器92が中温中圧の冷媒が流れる再熱器として機能するため、吸込空気の温度以上で、絶対湿度の低い吹出空気となり、吹出口87から吹き出され、温度は下がらず、絶対湿度が下がる。
これにより、空調部20は、再熱除湿サーモON状態が長時間継続し、圧縮機(図示せず)が継続して運転するので、熱交換器91(蒸発器)の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、熱交換器91(蒸発器)に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下する。
なお、本実施の形態では、熱交換器92(再熱器)に冷媒を流すヒートポンプ式としたが、再熱器として、燃料電池などを熱源として発生した温水を流す熱交換器でもよい。
以上により、空調送風路を通過する空調空気に埃、菌、水分等が少なく、空調送風路内も結露しにくいので、長時間運転しても、堆積した埃等に水分、カビ胞子等が付着し、カビ等が繁殖するということが少ない。 Even if the capacity of theair conditioning unit 20 is determined as described above, the change in the air conditioning load due to the outdoor temperature, for example, when the temperature is not so high during the rainy season, but when the humidity is high (temperature 27 ° C, relative humidity of 80% or more), when the air conditioning unit 20 is operated for cooling, the sensible heat capacity of a general air conditioner is high, so the temperature drops relatively quickly and the thermostat is turned off. The absolute humidity of the blowing air does not decrease, the absolute humidity of the conditioned air does not decrease, the relative humidity in the air-conditioning ventilation duct, room, and space through which the conditioned air flows does not decrease, only the temperature decreases, but the relative humidity increases. may be lost.
In such a case, the operation mode of theair conditioning unit 20 is set to reheat dehumidification operation, the heat exchanger 91 serves as an evaporator through which a low-temperature, low-pressure refrigerant flows, and the heat exchanger 92 serves as a reheater through which a medium-temperature, medium-pressure refrigerant flows. Since it functions, the air is blown out at a temperature higher than that of the intake air and with a low absolute humidity, and is blown out from the blow-out port 87 so that the temperature does not drop and the absolute humidity drops.
As a result, in theair conditioning unit 20, the reheat dehumidifying thermostat continues for a long time, and the compressor (not shown) continues to operate. However, the dew point temperature of the intake air becomes lower than the dew point temperature of the intake air, and the moisture of the intake air condenses on the heat exchanger 91 (evaporator). The absolute humidity of the conditioned air is lowered, the absolute humidity of the conditioned air is also lowered, and the relative humidity of the air-conditioned air passage, the room, and the space in which the conditioned air flows is also lowered.
In the present embodiment, the heat pump type heat exchanger 92 (reheater) is used, but the reheater may be a heat exchanger that uses hot water generated by a heat source such as a fuel cell.
Due to the above, the conditioned air passing through the air-conditioning air duct has little dust, bacteria, moisture, etc., and the inside of the air-conditioning air duct is less likely to condense. In addition, it is less likely that mold or the like will propagate.
このような場合は、空調部20の運転モードを再熱除湿運転とし、熱交換器91が低温低圧の冷媒が流れる蒸発器として、熱交換器92が中温中圧の冷媒が流れる再熱器として機能するため、吸込空気の温度以上で、絶対湿度の低い吹出空気となり、吹出口87から吹き出され、温度は下がらず、絶対湿度が下がる。
これにより、空調部20は、再熱除湿サーモON状態が長時間継続し、圧縮機(図示せず)が継続して運転するので、熱交換器91(蒸発器)の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、熱交換器91(蒸発器)に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下する。
なお、本実施の形態では、熱交換器92(再熱器)に冷媒を流すヒートポンプ式としたが、再熱器として、燃料電池などを熱源として発生した温水を流す熱交換器でもよい。
以上により、空調送風路を通過する空調空気に埃、菌、水分等が少なく、空調送風路内も結露しにくいので、長時間運転しても、堆積した埃等に水分、カビ胞子等が付着し、カビ等が繁殖するということが少ない。 Even if the capacity of the

As a result, in the
In the present embodiment, the heat pump type heat exchanger 92 (reheater) is used, but the reheater may be a heat exchanger that uses hot water generated by a heat source such as a fuel cell.
Due to the above, the conditioned air passing through the air-conditioning air duct has little dust, bacteria, moisture, etc., and the inside of the air-conditioning air duct is less likely to condense. In addition, it is less likely that mold or the like will propagate.
本実施の形態では、排気ダクトA65、給気ダクトA68、給気ダクトB72及び吹出ダクト36についても、できる限り、結露による水分発生と埃等の堆積によるカビ等の繁殖を抑え、定期的なダクト内の清掃や交換などのメンテナンスの頻度が少なくなるようなダクトを使用している。
一般的に、ダクトの内側表面に、ポリプロピレンなどの不織布がある場合、その不織布に通気性、透湿性があり、不織布の内側の断熱材等に埃と水分とカビ胞子等が付着してカビが繁殖する場合がある。
また、断熱材がグラスウールの場合は、その表面張力や毛細管現象により水分が繊維の隙間に入り込んでしまうと、乾いたとしても、繊維同士がくっついてしまい、断熱機能に必要な大量の空気を溜め込むことができなくなり、断熱機能が低下するため、一度ダクト内部に結露すると、ますます、結露しやすくなる。
また、不織布は、表面粗さ(表面の凸凹)も大きいので、何らかの理由で通過する空気に埃等が多く含まれる場合、不織布に引っかかって、堆積していきやすい。
さらに、ダクト内をブラシ等が回転する機械を使用して清掃する場合、ブラシが不織布の表面の凸凹に引っかかって、不織布が破損する可能性もある。
このような場合は、排気ダクトA65、給気ダクトA68、給気ダクトB72及び吹出ダクト36に、グラスウールなどの断熱材の内側で、空調空気が通過するダクト内側表面に、ポリエステル不織布などに対して、非通気性、非透湿性で、表面粗さ(表面の凹凸)が小さい、厚み0.1mm程度のポリプロピレンフィルム、軟質塩化ビニルフィルム、PETフィルムなどの内部被覆材を有するものを使用することにより、ダクト内側表面から、埃と水分とカビ胞子等がグラスウールに入り込まず、そこでカビ等が繁殖しにくく、さらに表面に、埃等が堆積しにくく、水分も含まないので、カビ等が繁殖しにくく、定期的なダクト内の清掃や交換などのメンテナンスの頻度が少なくなり、建物2内に、ダクト内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。 In the present embodiment, the exhaust duct A65, the air supply duct A68, the air supply duct B72, and the blow-outduct 36 are also designed to suppress moisture generation due to dew condensation and propagation of mold due to accumulation of dust as much as possible. Uses ducts that reduce the frequency of maintenance such as internal cleaning and replacement.
In general, if there is a nonwoven fabric such as polypropylene on the inner surface of the duct, the nonwoven fabric is breathable and moisture permeable, and dust, moisture, mold spores, etc. adhere to the heat insulating material inside the nonwoven fabric, causing mold. May reproduce.
Also, if the insulation material is glass wool, if water enters the gaps between the fibers due to its surface tension and capillary action, the fibers will stick together even if they are dry, and a large amount of air necessary for the insulation function will accumulate. As a result, the heat insulation function deteriorates, so once condensation occurs inside the duct, it becomes even more likely to occur.
In addition, since the nonwoven fabric has a large surface roughness (irregularities on the surface), if for some reason a large amount of dust or the like is contained in the passing air, it is likely to be caught on the nonwoven fabric and deposited.
Furthermore, when cleaning the inside of the duct using a machine with a rotating brush or the like, the brush may get caught on the irregularities on the surface of the nonwoven fabric and damage the nonwoven fabric.
In such a case, inside the exhaust duct A65, the air supply duct A68, the air supply duct B72, and the blowingduct 36, inside the heat insulating material such as glass wool, on the inner surface of the duct through which the conditioned air passes, polyester nonwoven fabric etc. By using a non-breathable, non-moisture permeable, low surface roughness (surface irregularity), polypropylene film, soft vinyl chloride film, PET film, or other internal covering material with a thickness of about 0.1 mm. Dust, moisture, mold spores, etc. do not enter the glass wool from the inner surface of the duct, making it difficult for mold to grow there. , the frequency of maintenance such as periodical cleaning and replacement of the inside of the duct is reduced, and a healthy and comfortable space can be realized in which dust, mold, bacteria, odors, etc. in the duct are difficult to enter into the building 2. - 特許庁

給気ダクトB72については、外気清浄フィルタ69通過により、埃、カビ胞子の侵入は抑えられるが、捕集効率が100%ではなく、熱交換素子63で、室内空気と全熱交換されることにより、結露は抑えられるが、厳冬期や酷暑時は、結露する可能性が高いので、上記換気ダクトを使用することにより、ダクト内でカビ等が繁殖するリスクは減少し、建物2内に、ダクト内の埃やカビ、細菌、異臭などが入りにくい。給気ダクトA68については、上記換気ダクトを使用することにより、少なくとも給気ダクトA68の内側に、埃、カビ胞子、水分等は付着しにくく、汚れの進行は遅くなり、屋外給気フード67での室外空気との接触による結露も減少する。排気ダクトA65については、上記換気ダクトを使用することにより、少なくとも排気ダクトA65の内側に、埃、カビ胞子、水分等は付着しにくく、汚れの進行は遅くなると共に、屋外排気フードA66から、埃、カビ胞子、水分等が排出されやすく、屋外排気フードA66での室外空気との接触による結露も減少する。
Regarding the air supply duct B72, the entry of dust and mold spores is suppressed by passing through the outside air cleaning filter 69, but the collection efficiency is not 100%, and the heat exchange element 63 exchanges all the heat with the indoor air. , dew condensation can be suppressed, but there is a high possibility of dew condensation in severe winters and extreme heat. It is difficult for dust, mold, bacteria, and odors to enter inside. As for the air supply duct A68, by using the ventilation duct described above, it is difficult for dust, mold spores, moisture, etc. to adhere to at least the inside of the air supply duct A68. Condensation due to contact with outdoor air is also reduced. As for the exhaust duct A65, by using the ventilation duct described above, it is difficult for dust, mold spores, moisture, etc. to adhere to at least the inside of the exhaust duct A65, slowing down the progress of dirt, and removing dust from the outdoor exhaust hood A66. , mold spores, moisture, etc. are easily discharged, and dew condensation due to contact with outdoor air in the outdoor exhaust hood A66 is also reduced.
室温コントローラ120の温度設定部125で温度を設定し、本空調換気システム1の運転を行うと、空調部20と複数の送風部17と空気清浄機90と熱交換気ユニット60が、空調ユニットコントローラ110により、適正に制御、運転されるが、その内容は下記となる。

また、室温コントローラ120の温度設定部125で設定された温度データを制御部124に送り、信号線150で制御部124から制御部114にデータが送られる。 When the temperature is set by thetemperature setting unit 125 of the room temperature controller 120 and the air conditioning ventilation system 1 is operated, the air conditioning unit 20, the plurality of air blowing units 17, the air purifier 90, and the heat exchange air unit 60 are controlled by the air conditioning unit controller. 110 is properly controlled and operated, the contents of which are as follows.
Atemperature sensor 111 of an air conditioning unit controller 110 detects the temperature, humidity, and dust concentration of the conditioned air in the mixing section 95 in the air conditioning unit 10, a humidity sensor 112 detects the humidity of the air, and a dust sensor detects the mass concentration of dust in the air. The sensor 113 detects the temperature of the air sucked in from the return air port 55 (in the second floor hall 15, the return air from the rooms and spaces and the introduced outdoor air is mixed) temperature sensor 121 of the room temperature controller 120 Detected by a humidity sensor 122 that detects the humidity of the air and a dust sensor 123 that detects the mass concentration of dust in the air. 114 the data is sent.
Also, the temperature data set by thetemperature setting unit 125 of the room temperature controller 120 is sent to the control unit 124 , and the data is sent from the control unit 124 to the control unit 114 via the signal line 150 .

制御部114では、温度センサー121で検出した温度と温度設定部125で設定された温度を比較して、空調部20の運転モードを冷房/暖房のいずれかに決定し、冷房運転の場合は、湿度センサー122で検出した湿度を閾値とを比較して、閾値より低い場合は冷房運転とし、閾値より高い場合は再熱除湿運転と決定する。
また、制御部114では、温度センサー121で検出した還気口55から吸い込まれる空気の温度から、部屋、空間の平均温度を推定し、温度センサー111で検出した混合部95の空調空気の温度から、空調送風路A30、空調送風路B31内の空気の平均温度を推定し、部屋、空間の平均温度が設定温度となるように、また、部屋、空間の平均温度を空調送風路の周囲の空気の平均温度とし、それに対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるように、空調部20の設定温度と送風部17の送風量を決定し、先程決定した空調部20の運転モード(冷房/暖房/再熱除湿)と空調部20の設定温度と送風部17の送風量を、それぞれ信号線151を通じて、空調部20の制御部130に信号を送り、信号線153を通じて、複数の送風部17の制御部140に信号を送る。 Thecontrol unit 114 compares the temperature detected by the temperature sensor 121 with the temperature set by the temperature setting unit 125, and determines the operation mode of the air conditioning unit 20 to be either cooling or heating. The humidity detected by the humidity sensor 122 is compared with a threshold value, and if it is lower than the threshold value, the cooling operation is performed, and if it is higher than the threshold value, the reheat dehumidification operation is determined.
In addition, thecontrol unit 114 estimates the average temperature of the room and space from the temperature of the air sucked in from the return air port 55 detected by the temperature sensor 121, , the average temperature of the air in the air conditioning duct A30 and the air conditioning duct B31 is estimated, and the average temperature of the room and space is adjusted to the set temperature. The set temperature of the air conditioning unit 20 and the air blowing amount of the air blowing unit 17 are determined so that the average temperature of the air in the air conditioning blow passage is within 5 K during cooling and within 10 K during heating. , the previously determined operation mode (cooling/heating/reheat dehumidification) of the air conditioning unit 20, the set temperature of the air conditioning unit 20, and the air blowing volume of the air blowing unit 17 are respectively signaled to the control unit 130 of the air conditioning unit 20 through the signal line 151. and send signals to the controllers 140 of the plurality of air blowers 17 through the signal line 153 .
また、制御部114では、温度センサー121で検出した還気口55から吸い込まれる空気の温度から、部屋、空間の平均温度を推定し、温度センサー111で検出した混合部95の空調空気の温度から、空調送風路A30、空調送風路B31内の空気の平均温度を推定し、部屋、空間の平均温度が設定温度となるように、また、部屋、空間の平均温度を空調送風路の周囲の空気の平均温度とし、それに対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるように、空調部20の設定温度と送風部17の送風量を決定し、先程決定した空調部20の運転モード(冷房/暖房/再熱除湿)と空調部20の設定温度と送風部17の送風量を、それぞれ信号線151を通じて、空調部20の制御部130に信号を送り、信号線153を通じて、複数の送風部17の制御部140に信号を送る。 The
In addition, the
送風部17の送風量については、例えば、建物の床面積が約100m2、天井高さは2.5mで、冷房能力4kW相当、弱風モード冷房運転時空調風量600m3/hである空調部20を設置した場合、送風部17は、1台あたりの送風量が、弱風量で100m3/h程度、最大風量で300m3/hのものを10台設置し、10台の送風部17の合計送風量は1000m3/h~2000m3/hとし、空調部20の空調風量よりも多く、合計送風量の30~60%の風量が空調部20の空調風量(弱風モード)となるように、100m3/hから300m3/hの間で決定し、本空調換気システム1の運転中は、送風量を0とせず、空調送風路内の空調空気の風速を常に0.5m/s以上で制御する。
一般的に、水面上の空気の移動による水の蒸発速度Y(kg/m2s)は、水面の飽和蒸気量Xw(kg/m3)、水面上の空気の水蒸気量Xa(kg/m3)、水面上の空気の移動速度V(m/s)により、Y=K・V(Xw―Xa)となり、移動速度に比例する。これを空調送風路にあてはめた時、空調送風路内周表面上に結露した水分は、空調空気の風速に比例してその蒸発量が増えるので、本空調換気システム1では、仮に空調送風路内に結露した場合でも、できる限り早く蒸発させるため、送風量を0とせず、常に空調空気を流し続ける仕様としている。 Regarding the air blowing volume of theair blowing unit 17, for example, the building has a floor area of about 100 m 2 and a ceiling height of 2.5 m. 20, the air blowing volume per unit is about 100 m 3 /h at a weak air volume and 300 m 3 /h at a maximum air volume. The total blast volume is set to 1000 m 3 /h to 2000 m 3 /h, which is greater than the conditioned air volume of the air conditioning unit 20, and the air volume of 30 to 60% of the total blast volume is the air conditioned air volume of the air conditioning unit 20 (weak wind mode). Then, it is determined between 100 m 3 /h and 300 m 3 /h, and during operation of the air conditioning ventilation system 1, the air flow rate is not set to 0, and the wind speed of the conditioned air in the air conditioning air passage is always 0.5 m / s. Control with the above.
In general, the evaporation rate Y (kg/m 2 s) of water due to movement of air on the water surface is determined by the saturated vapor amount Xw (kg/m 3 ) on the water surface, the water vapor amount Xa (kg/m 3 ) Y=K·V (Xw−Xa), which is proportional to the moving speed of the air above the water surface V (m/s). When this is applied to the air-conditioning air passage, the amount of moisture condensed on the inner peripheral surface of the air-conditioning air passage increases in proportion to the wind speed of the conditioned air. In order to evaporate as quickly as possible even if dew condensation occurs, the air flow rate is not set to 0, and the conditioned air is always flowing.

送風部17は、運転中は、回転数は制御されるが、停止することはなく、シロッコファンを回転し続け、空調送風路に送風し続ける。これは、空調送風路内の空気を動かし続け、表面の埃等を吹出口から掃き出し、水分を蒸発させ、空調送風路内外を含め、建物2内の温湿度を均一にすることに有効だからである。
また、基本的に、空調ユニットコントローラ110による運転は、メンテナンス等による停止と長期不在時を除いて、24時間365日連続とするのが望ましい。送風部17は、高効率なDCモーター(図示せず)で回転させるので、もともと省エネで、回転数に比例して消費電力がさらに下がるが、空調室外機18の圧縮機は、本システムの消費電力に占める割合が大きい。従って、連続運転していても、室外温度や日射により、よほど空調負荷が大きくなければ、安定時は、圧縮機が低周波数で運転するか、停止するため、送風部17が、運転し続けても、システムの消費電力は非常に少ないのに対し、空調送風路の埃、カビ、水分の付着、堆積の防止には、大変有効だからである。
また、「部屋、空間の平均温度を設定温度とすること」と、「空調送風路の周囲の空気の平均温度に対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるようにすること」が両立しない場合は、通常、ユーザー視点で、「部屋、空間の平均温度を設定温度とすること」を優先する制御となっているが、運転開始時で、空調負荷が大きい時など、空調ユニットコントローラ110に設けられた隠し操作(例えば、運転開始時に設定温度を最低又は最高温度とするなど)により、「空調送風路の周囲の空気の平均温度に対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるようにすること」を優先するモードに変更可能である。
しかし、基本的に、空調送風路内を通過する空気の水分、埃、菌等が通常のダクト式空調換気システムに比べると大幅に少なく、高気密高断熱な建物2に適正な能力の空調部20を設け、送風部17の合計送風量を空調部20の空調風量よりも多くし、合計送風量の30~60%の風量が空調部20の空調風量(弱風モード)として設定することにより、長時間運転した安定時は、空調部20の吹出空気の温度は吸込空気の温度とほぼ等しくなり、空調送風路内の空気の平均温度は空調送風路の周囲の空気の平均温度とほぼ等しくなるので、空調送風路内に、埃等が堆積しにくく、水分も含みにくいので、カビ等が繁殖しにくい。 Theair blower 17 is controlled in rotation speed during operation, but does not stop, and continues to rotate the sirocco fan and blow air to the air conditioning air passage. This is because it is effective in keeping the air in the air-conditioning ducts moving, sweeping out surface dust and the like from the air outlet, evaporating moisture, and making the temperature and humidity in the building 2 uniform, including inside and outside the air-conditioning ducts. be.
Basically, it is desirable that the operation by the air-conditioning unit controller 110 should be continuous 24 hours a day, 365 days a year, except for maintenance stoppages and long-term absences. Since the blower unit 17 is rotated by a highly efficient DC motor (not shown), it is originally energy saving, and the power consumption is further reduced in proportion to the rotation speed, but the compressor of the air conditioning outdoor unit 18 is the consumption of this system. It accounts for a large proportion of electricity. Therefore, even in continuous operation, if the air conditioning load is not particularly large due to the outdoor temperature or solar radiation, the compressor operates at a low frequency or stops during stable operation, so the air blower 17 continues to operate. Although the power consumption of the system is very low, it is very effective in preventing the adhesion and deposition of dust, mold, and moisture in the air-conditioning air duct.
In addition, "the average temperature of the room and space should be set as the set temperature," and "the air in the air-conditioning ventilation path should be within 5K during cooling and within 10K during heating, relative to the average temperature of the air around the air-conditioning ventilation path." If it is not possible to achieve both the average temperature of the , when the air conditioning load is large, hidden operations provided in the air conditioning unit controller 110 (for example, the set temperature is set to the minimum or maximum temperature at the start of operation, etc.) , keeping the average temperature of the air in the air conditioning duct within 5 K during cooling and within 10 K during heating.
However, basically, the amount of moisture, dust, bacteria, etc. in the air passing through the air-conditioning air passage is significantly less than in a normal duct-type air-conditioning and ventilation system, and the air-conditioning unit with an appropriate capacity for a highly airtight and highlyinsulated building 2. 20 is provided, the total blowing volume of the blowing unit 17 is made larger than the air conditioning air volume of the air conditioning unit 20, and the air volume of 30 to 60% of the total air volume is set as the air conditioning air volume of the air conditioning unit 20 (weak wind mode). When the air conditioner is operated for a long time and is stable, the temperature of the blown air from the air conditioning unit 20 is approximately equal to the temperature of the intake air, and the average temperature of the air in the air conditioning duct is approximately equal to the average temperature of the air around the air conditioning duct. As a result, it is difficult for dust and the like to accumulate in the air-conditioning air duct, and it is difficult for the air-conditioning air passage to contain moisture, so mold and the like are less likely to propagate.
また、基本的に、空調ユニットコントローラ110による運転は、メンテナンス等による停止と長期不在時を除いて、24時間365日連続とするのが望ましい。送風部17は、高効率なDCモーター(図示せず)で回転させるので、もともと省エネで、回転数に比例して消費電力がさらに下がるが、空調室外機18の圧縮機は、本システムの消費電力に占める割合が大きい。従って、連続運転していても、室外温度や日射により、よほど空調負荷が大きくなければ、安定時は、圧縮機が低周波数で運転するか、停止するため、送風部17が、運転し続けても、システムの消費電力は非常に少ないのに対し、空調送風路の埃、カビ、水分の付着、堆積の防止には、大変有効だからである。
また、「部屋、空間の平均温度を設定温度とすること」と、「空調送風路の周囲の空気の平均温度に対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるようにすること」が両立しない場合は、通常、ユーザー視点で、「部屋、空間の平均温度を設定温度とすること」を優先する制御となっているが、運転開始時で、空調負荷が大きい時など、空調ユニットコントローラ110に設けられた隠し操作(例えば、運転開始時に設定温度を最低又は最高温度とするなど)により、「空調送風路の周囲の空気の平均温度に対し、冷房時は5K以内、暖房時は10K以内の空調送風路内の空気の平均温度となるようにすること」を優先するモードに変更可能である。

なお、本実施の形態では、建物2は、省施工で、断熱施工面積を減らすことのできる、天井断熱仕様、床断熱仕様として、1階と2階の階間空間に空調送風路を設け、1階の天井32及び2階の床33に吹出口を設けたが、建物2内の有効スペースを増やし、建物2の躯体自体の耐久性を上げるため、屋根断熱仕様や基礎断熱仕様とし、屋根裏空間9、床下空間12を断熱空間として、そこに空調ユニット10、空調送風路を設け、2階の天井3や1階の床5に吹出口を設けて、空調ユニット10から屋根裏空間9、床下空間12の空調送風路を通して、各吹出口から空調空気を吹き出してもよく、各部屋、各空間の温度分布や障害物等により、吹出口をそれぞれ床と天井に選択でき、屋根裏空間や床下空間も断熱空間となるため、建物2内の均一な空気質にできる空間が広がり、屋根裏や床下を倉庫や納戸、音楽などの趣味の部屋に使用しながら、空調送風路の結露や埃の堆積、カビの繁殖等を防止できる。
しかし、屋根裏空間9も床下空間も外皮に近く、屋根裏空間9の上部の屋根8からの日射負荷や、床下空間12の基礎4からの伝熱負荷等により、空調負荷が大きくなるので、断熱欠損などなく、しっかりと断熱気密をとり、空調部の選定においても、上記の空調負荷の増加分を考慮する必要がある。
また、屋根断熱仕様、基礎断熱仕様であっても、断熱空間である屋根裏空間9、床下空間12に空調送風路を設けない場合でも、屋根裏空間9、床下空間12に吹出口を設けて、送風部17と前記吹出口を空調ダクト等で繋いで空調空気を送風した場合、空調ダクト等が通っている空間を空調することになるので、空調ダクト等の内外の結露を防止しながら、空調負荷の変化や断熱材等の経年劣化のリスクに備えることができる。そして、建物2全体を空調空気で空調するので、建物2全体が、部屋間、空間温度差の少ない均一な温度になり、熱の移動も少なく、快適な空間を維持するのにかえって省エネとなり、特に屋根裏空間9と床下空間12は、建物2の外壁に面した大きな空間のため、建物2にとってさらに高断熱化となり、省エネ空調となる。
なお、本実施の形態では、空調部20を熱交換器91、92と送風機90が一体の筐体に収められた、いわゆる空調室内機として、送風部17をいわゆる送風機として、空調ユニット10を空調室である四方を断熱壁に囲まれた1坪程度の比較的コンパクトな部屋として説明しているが、空調ユニット10を板金などに囲まれた筐体とし、筐体内に、空調部20として、熱交換器だけを設け、送風部17として、複数の送風機を設け、複数の送風機により、空調ユニット10に吸い込まれる空気の一部を熱交換器に通過することにより吹出空気とし、空調ユニット10に吸い込まれる空気の一部を熱交換器を通過させないバイパス空気とし、バイパス空気と吹出空気とを筐体内で混合させて空調空気とし、この空調空気を各部屋、各空間に送風してもよい。その場合でも、空調部20、複数の送風部17、及び空気清浄機90は、清掃などのメンテナンスや作業が容易な大きさ、構造とすることが望ましい。 In the present embodiment, thebuilding 2 has a ceiling heat insulation specification and a floor heat insulation specification that can reduce the construction area and reduce the heat insulation construction area. The ceiling 32 on the 1st floor and the floor 33 on the 2nd floor are provided with air outlets, but in order to increase the effective space in the building 2 and to increase the durability of the frame itself of the building 2, the roof insulation specification and basic insulation specification are used, and the attic A space 9 and an underfloor space 12 are used as a heat insulating space, and an air conditioning unit 10 and an air conditioning ventilation passage are provided there. The conditioned air may be blown out from each outlet through the conditioned air passage of the space 12, and depending on the temperature distribution and obstacles in each room and space, the outlet can be selected from the floor and the ceiling, and the attic space and the underfloor space can be selected. Since this is also a heat insulating space, the space where the air quality in the building 2 can be uniform is expanded, and while using the attic and underfloor as a storage room, a storage room, a room for hobbies such as music, condensation and dust accumulation in the air conditioning ventilation path, It is possible to prevent the growth of mold and the like.
However, both theattic space 9 and the underfloor space are close to the outer skin, and the air conditioning load increases due to the solar radiation load from the roof 8 above the attic space 9 and the heat transfer load from the foundation 4 of the underfloor space 12, etc., resulting in insulation loss. Therefore, it is necessary to ensure proper insulation and airtightness, and to consider the above increase in air conditioning load when selecting an air conditioning unit.
In addition, even if the roof insulation specification and basic insulation specification are used, even if theattic space 9 and the underfloor space 12, which are heat insulating spaces, are not provided with an air-conditioning air duct, air outlets are provided in the attic space 9 and the underfloor space 12 to blow air. If the air conditioning duct or the like is connected between the portion 17 and the air outlet to blow conditioned air, the space through which the air conditioning duct or the like passes will be air conditioned. It is possible to prepare for the risk of changes in the temperature and deterioration of insulation materials over time. Since the entire building 2 is air-conditioned with conditioned air, the temperature of the entire building 2 becomes uniform with little spatial temperature difference between rooms, heat transfer is small, and even though a comfortable space is maintained, energy is saved. In particular, since the attic space 9 and the underfloor space 12 are large spaces facing the outer wall of the building 2, the building 2 can be further heat-insulated and energy-saving air conditioning can be achieved.
In the present embodiment, theair conditioning unit 20 is a so-called air conditioning indoor unit in which the heat exchangers 91 and 92 and the blower 90 are housed in an integrated housing, the blower unit 17 is a so-called blower, and the air conditioning unit 10 is an air conditioner. The room is described as a relatively compact room of about 1 tsubo surrounded by heat insulating walls on all sides, but the air conditioning unit 10 is a housing surrounded by sheet metal or the like, and the air conditioning unit 20 is provided in the housing. Only a heat exchanger is provided, and a plurality of blowers are provided as the air blower section 17. By the plurality of blowers, part of the air sucked into the air conditioning unit 10 is blown out by passing through the heat exchanger, and the air is blown out to the air conditioning unit 10. A part of the sucked air may be used as bypass air that does not pass through the heat exchanger, the bypass air and the blown air may be mixed in the housing to obtain conditioned air, and this conditioned air may be blown to each room and each space. Even in that case, it is desirable that the air conditioner 20, the plurality of blowers 17, and the air purifier 90 have sizes and structures that facilitate maintenance and work such as cleaning.
しかし、屋根裏空間9も床下空間も外皮に近く、屋根裏空間9の上部の屋根8からの日射負荷や、床下空間12の基礎4からの伝熱負荷等により、空調負荷が大きくなるので、断熱欠損などなく、しっかりと断熱気密をとり、空調部の選定においても、上記の空調負荷の増加分を考慮する必要がある。
また、屋根断熱仕様、基礎断熱仕様であっても、断熱空間である屋根裏空間9、床下空間12に空調送風路を設けない場合でも、屋根裏空間9、床下空間12に吹出口を設けて、送風部17と前記吹出口を空調ダクト等で繋いで空調空気を送風した場合、空調ダクト等が通っている空間を空調することになるので、空調ダクト等の内外の結露を防止しながら、空調負荷の変化や断熱材等の経年劣化のリスクに備えることができる。そして、建物2全体を空調空気で空調するので、建物2全体が、部屋間、空間温度差の少ない均一な温度になり、熱の移動も少なく、快適な空間を維持するのにかえって省エネとなり、特に屋根裏空間9と床下空間12は、建物2の外壁に面した大きな空間のため、建物2にとってさらに高断熱化となり、省エネ空調となる。
なお、本実施の形態では、空調部20を熱交換器91、92と送風機90が一体の筐体に収められた、いわゆる空調室内機として、送風部17をいわゆる送風機として、空調ユニット10を空調室である四方を断熱壁に囲まれた1坪程度の比較的コンパクトな部屋として説明しているが、空調ユニット10を板金などに囲まれた筐体とし、筐体内に、空調部20として、熱交換器だけを設け、送風部17として、複数の送風機を設け、複数の送風機により、空調ユニット10に吸い込まれる空気の一部を熱交換器に通過することにより吹出空気とし、空調ユニット10に吸い込まれる空気の一部を熱交換器を通過させないバイパス空気とし、バイパス空気と吹出空気とを筐体内で混合させて空調空気とし、この空調空気を各部屋、各空間に送風してもよい。その場合でも、空調部20、複数の送風部17、及び空気清浄機90は、清掃などのメンテナンスや作業が容易な大きさ、構造とすることが望ましい。 In the present embodiment, the

なお、本実施の形態の一例として、建物2の床面積が約100m2、天井高さは2.5mの場合、各部屋や各空間を均一な温度に省エネで空調換気するために、各部屋や各空間に送風する合計送風量が1500m3/hであれば、循環回数6回/hとなり、空気清浄機90の処理風量も1500m3/hで、循環回数6回/hと言え、建物2全体の空調換気のための大風量の送風により、空調送風路内も含む建物2全体の空気清浄も行えるという合理的なシステムとなっている。
一般的に、電気式集塵式は、HEPAフィルタ式と比較して、通風抵抗が小さいので、送風部17の消費電力、運転騒音が小さく、目詰まりしにくく、寿命が長いというメリットがある反面、一過性の集塵効率が低く、オゾン等の副生成物の発生があるというデメリットがある。
逆に、一般的に、HEPAフィルタ式は、通風抵抗が大きく、送風部17の消費電力、運転騒音が大きく、目詰まりしやすく、寿命が短いというデメリットがある反面、一過性の集塵効率が高く、より細かい粒子径の物質を短時間で捕捉しやすく、オゾン等の副生成物の発生がないというメリットがある。
本実施の形態で、除去したい埃、カビ胞子レベルの粒子は、長時間運転すれば、いずれの方式でも除去できるため、その他の除去したい有害物質等の種類及びその程度、機械の形状、空調ユニット10の形状、空調ユニット10内の空気の風速、メンテナンスの頻度、ユーザーの重要視するポイント等により選択すればよい。
特に、HEPAフィルタ式の場合、それだけの大風量を通過させると、送風部17の性能(P-Q等)を大幅に向上させなければならず、また、騒音も増大するが、本実施の形態では、複数の送風部17、例えば、10台の送風部17で送風し、建物2内を循環させるため、1台当たりの送風部17の性能向上は緩和される。また、1台当たりの送風量を増加させるのは、各送風部17のDCモーターの回転数を上げることで容易であり、消費電力の増加量がACモーターに比べると少なく、合理的に、省エネ高効率で、合計送風量を増やし、建物2内の空気を清浄できる。
さらに、HEPAフィルタの通過風速を1m/s以下となるような空調ユニット10の還気口55の大きさとすれば、騒音の増大は抑えられるが、空調ユニット10を大きくすることは、建物2内のスペースが十分あれば、比較的容易である。 As an example of the present embodiment, when thebuilding 2 has a floor area of about 100 m 2 and a ceiling height of 2.5 m, in order to air-condition and ventilate each room and each space to a uniform temperature with energy saving, each room If the total amount of air blown to each space is 1500 m 3 /h, the number of circulations will be 6 times/h, and the processing air volume of the air purifier 90 is also 1500 m 3 /h, so the number of circulations is 6 times/h. It is a rational system that cleans the air of the entire building 2 including the inside of the air-conditioning ventilation path by blowing a large amount of air for the air-conditioning and ventilation of the entire building 2.
In general, the electric dust collection system has lower ventilation resistance than the HEPA filter system, so it has the merits of low power consumption and operating noise of theair blower 17, less clogging, and a longer service life. However, it has the disadvantages of low transient dust collection efficiency and generation of by-products such as ozone.
Conversely, in general, the HEPA filter type has the disadvantages of high ventilation resistance, high power consumption of theair blower 17, large operating noise, easy clogging, and short life. It has the advantages of being high in particle size, easy to capture substances with finer particle diameters in a short time, and not generating by-products such as ozone.
In this embodiment, the dust and mold spore level particles to be removed can be removed by any method if the operation is performed for a long time. 10, the wind speed of the air in theair conditioning unit 10, the frequency of maintenance, and the user's point of view.
In particular, in the case of the HEPA filter type, if such a large amount of air is passed through, the performance (PQ, etc.) of theblower section 17 must be greatly improved, and noise also increases. A plurality of air blowers 17, for example, ten air blowers 17 blow air and circulate in the building 2, so the performance improvement of each air blower 17 is moderated. In addition, it is easy to increase the amount of air blown per unit by increasing the rotation speed of the DC motor of each air blower 17, and the amount of increase in power consumption is less than that of the AC motor, so it is reasonably energy-saving. The air in the building 2 can be cleaned with high efficiency by increasing the total blowing volume.
Furthermore, if the size of thereturn air port 55 of the air conditioning unit 10 is set so that the air velocity passing through the HEPA filter is 1 m/s or less, the increase in noise can be suppressed. If you have enough space, it's relatively easy.
一般的に、電気式集塵式は、HEPAフィルタ式と比較して、通風抵抗が小さいので、送風部17の消費電力、運転騒音が小さく、目詰まりしにくく、寿命が長いというメリットがある反面、一過性の集塵効率が低く、オゾン等の副生成物の発生があるというデメリットがある。
逆に、一般的に、HEPAフィルタ式は、通風抵抗が大きく、送風部17の消費電力、運転騒音が大きく、目詰まりしやすく、寿命が短いというデメリットがある反面、一過性の集塵効率が高く、より細かい粒子径の物質を短時間で捕捉しやすく、オゾン等の副生成物の発生がないというメリットがある。
本実施の形態で、除去したい埃、カビ胞子レベルの粒子は、長時間運転すれば、いずれの方式でも除去できるため、その他の除去したい有害物質等の種類及びその程度、機械の形状、空調ユニット10の形状、空調ユニット10内の空気の風速、メンテナンスの頻度、ユーザーの重要視するポイント等により選択すればよい。
特に、HEPAフィルタ式の場合、それだけの大風量を通過させると、送風部17の性能(P-Q等)を大幅に向上させなければならず、また、騒音も増大するが、本実施の形態では、複数の送風部17、例えば、10台の送風部17で送風し、建物2内を循環させるため、1台当たりの送風部17の性能向上は緩和される。また、1台当たりの送風量を増加させるのは、各送風部17のDCモーターの回転数を上げることで容易であり、消費電力の増加量がACモーターに比べると少なく、合理的に、省エネ高効率で、合計送風量を増やし、建物2内の空気を清浄できる。
さらに、HEPAフィルタの通過風速を1m/s以下となるような空調ユニット10の還気口55の大きさとすれば、騒音の増大は抑えられるが、空調ユニット10を大きくすることは、建物2内のスペースが十分あれば、比較的容易である。 As an example of the present embodiment, when the

本実施の形態では、複数のフィルタ部と空気清浄機90を、空調ユニット10内の風路の上流から空調送風路A30、空調送風路B31に向かって順に、還気口フィルタ85(効率80%以上)、空調部フィルタ86(効率低い)、空気清浄機90のプレフィルタ、空気清浄機90(0.3μmの粒子も捕集可能)と配置し、空調送風路A30の直前に、送風部フィルタ87(効率30%)を設けたが、送風部フィルタ87を除いて、フィルタ部、空気清浄機90は、循環路を通過する空気を効率よく清浄し、メンテナンスが容易であれば、循環路の途中に設けてもよく、また、フィルタ部と空気清浄機90の循環路、空調ユニット10内における配置の順番については、捕集可能な粒子が大きいものもしくは、捕集効率が低いものを上流に、捕集可能な粒子が小さいものもしくは、捕集効率が高いもの下流にすると、フィルタ部と空気清浄機の圧損が急激に増加せず、結果、省エネで、清掃などのメンテナンス頻度を減らせることができる。
また、あくまで、複数のフィルタ部の主目的は、カビの繁殖条件の一つである埃等を除去することであり、空気清浄機90の主目的は、居住空間を快適にするための直接的な空気浄化で、カビ胞子やPM2.5レベルの粒子を捕集することも可能であるということであるので、その目的を考慮してフィルタ部と空気清浄機90を配置すべきである。
また、本実施の形態の送風部フィルタ87は、空調空気の清浄や、送風部フィルタ87の上流の混合部95での空調空気の混合促進等に有効であるが、その他として、空調送風路A30の直前に、フィルタ部を設けているので、その上流にある風路やその他のフィルタ部や空気清浄機90に洩れがあった場合でも、埃等の侵入を確実に抑えるのに有効である。
例えば、送風部フィルタ87はメンテナンス頻度と混合促進度合のバランスを考慮してそのままの位置に設け、プレ還気口フィルタ(効率30%)を、還気口フィルタ85の上流に追加で設け、順に、プレ還気口フィルタ(効率30%)、還気口フィルタ85(効率80%以上)、空調部フィルタ86(効率低い)、空気清浄機90のプレフィルタ、空気清浄機90(0.3μmの粒子も捕集可能)、送風部フィルタ87とするのが、合理的である。
また、空調部フィルタ86(効率低い)については、循環路の中で、空調部フィルタ86をバイパスする風路があり、空調部フィルタ86の効率を増やすと、バイパスする風量が増え、空調部20の風量が減ることに注意する必要がある。
また、本実施の形態では、気密断熱された空調ユニット10内で、空調送風路A30の入り口の送風部17のほぼ直前に、再熱除湿機能付きの空調部20、混合部95を設けているので、絶対湿度を下げ、温湿度を適正とした空調空気を、直接、空調送風路A30、空調送風路B31に送風でき、空調送風路内の結露を防止できる。 In the present embodiment, the plurality of filter units and theair purifier 90 are arranged in order from the upstream side of the air passage in the air conditioning unit 10 toward the air conditioning air passage A30 and the air conditioning air passage B31. above), the air conditioner filter 86 (low efficiency), the pre-filter of the air cleaner 90, the air cleaner 90 (can also collect particles of 0.3 μm), and the air blower filter 87 (efficiency 30%) is provided, but except for the blower filter 87, the filter part and the air cleaner 90 efficiently clean the air passing through the circulation path, and if maintenance is easy, the circulation path It may be provided in the middle, and regarding the order of arrangement in the circulation path of the filter part and the air cleaner 90 and in the air conditioning unit 10, those with large particles that can be collected or those with low collection efficiency are upstream. , Those with small particles that can be collected or those with high collection efficiency. If placed downstream, the pressure loss in the filter and air purifier will not increase rapidly, resulting in energy savings and reduced maintenance frequency such as cleaning. can be done.
In addition, the main purpose of the plurality of filter units is to remove dust, which is one of the breeding conditions for mold. It means that it is possible to collect mold spores and PM2.5 level particles with moderate air purification, so the filter part and theair cleaner 90 should be arranged in consideration of that purpose.
Further, theblower filter 87 of the present embodiment is effective for cleaning the conditioned air and promoting mixing of the conditioned air in the mixing unit 95 upstream of the blower filter 87. Since the filter section is provided immediately before the , even if there is leakage in the air passage, other filter sections, or the air purifier 90 located upstream, it is effective in reliably suppressing the intrusion of dust and the like.
For example, theair blower filter 87 is provided at the position as it is in consideration of the balance between the maintenance frequency and the degree of mixing promotion, and the pre-return air port filter (efficiency 30%) is additionally provided upstream of the return air port filter 85. , pre-return air port filter (efficiency 30%), return air port filter 85 (efficiency 80% or more), air conditioning unit filter 86 (low efficiency), pre-filter of air cleaner 90, air cleaner 90 (0.3 μm Particles can also be collected), and it is rational to use the air blower filter 87 .
In addition, regarding the air conditioning unit filter 86 (low efficiency), there is an air passage that bypasses the airconditioning unit filter 86 in the circulation path. It should be noted that the air volume of
Further, in the present embodiment, the air-conditioning unit 20 with the reheat dehumidification function and the mixing unit 95 are provided in the air-tightly insulated air-conditioning unit 10 almost immediately before the air blowing unit 17 at the entrance of the air-conditioning air passage A30. Therefore, conditioned air with reduced absolute humidity and proper temperature and humidity can be blown directly to the air-conditioning air passages A30 and B31, and dew condensation in the air-conditioning air passages can be prevented.
また、あくまで、複数のフィルタ部の主目的は、カビの繁殖条件の一つである埃等を除去することであり、空気清浄機90の主目的は、居住空間を快適にするための直接的な空気浄化で、カビ胞子やPM2.5レベルの粒子を捕集することも可能であるということであるので、その目的を考慮してフィルタ部と空気清浄機90を配置すべきである。
また、本実施の形態の送風部フィルタ87は、空調空気の清浄や、送風部フィルタ87の上流の混合部95での空調空気の混合促進等に有効であるが、その他として、空調送風路A30の直前に、フィルタ部を設けているので、その上流にある風路やその他のフィルタ部や空気清浄機90に洩れがあった場合でも、埃等の侵入を確実に抑えるのに有効である。
例えば、送風部フィルタ87はメンテナンス頻度と混合促進度合のバランスを考慮してそのままの位置に設け、プレ還気口フィルタ(効率30%)を、還気口フィルタ85の上流に追加で設け、順に、プレ還気口フィルタ(効率30%)、還気口フィルタ85(効率80%以上)、空調部フィルタ86(効率低い)、空気清浄機90のプレフィルタ、空気清浄機90(0.3μmの粒子も捕集可能)、送風部フィルタ87とするのが、合理的である。
また、空調部フィルタ86(効率低い)については、循環路の中で、空調部フィルタ86をバイパスする風路があり、空調部フィルタ86の効率を増やすと、バイパスする風量が増え、空調部20の風量が減ることに注意する必要がある。
また、本実施の形態では、気密断熱された空調ユニット10内で、空調送風路A30の入り口の送風部17のほぼ直前に、再熱除湿機能付きの空調部20、混合部95を設けているので、絶対湿度を下げ、温湿度を適正とした空調空気を、直接、空調送風路A30、空調送風路B31に送風でき、空調送風路内の結露を防止できる。 In the present embodiment, the plurality of filter units and the
In addition, the main purpose of the plurality of filter units is to remove dust, which is one of the breeding conditions for mold. It means that it is possible to collect mold spores and PM2.5 level particles with moderate air purification, so the filter part and the

以上により、吸込部、空調部20及び送風部17を設けた空調ユニット10で作り出された、空調送風路A30、空調送風路B31周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の空調空気を大風量で空調送風路内に送風することにより、部屋A23、部屋B24、玄関13の吹出口40、41、42から吹き出し、高気密高断熱な建物2内の部屋及び上下の空間を空調するので、日射負荷などの空調負荷の大きい空間も含めて、建物2内は快適で均一な温湿度となりやすい。そして、空調送風路は、周囲を空調された部屋、空間又は断熱材で囲まれているため、冷房時の空調送風路内外の結露、暖房時の空調送風路内の結露は発生しにくい。
また、空調空気を作り出す空調ユニット10の吸込部に設けた還気口フィルタ85(フィルタ部A)により、空調ユニット10に吸い込まれる空気の全てが清浄され、さらに空調部20に吸い込まれた空気は、空調部フィルタ86(フィルタ部B)でさらに清浄し、複数の送風部17の送風部フィルタ87(フィルタ部C)で、空調ユニット10に吸い込まれた空気の全てを漏れなく清浄し、空調送風路A30、空調送風路B31に流入させ、建物2内の空気を清浄し、空調送風路に、カビの繁殖条件の一つである埃等が流入するリスクがさらに減少し、全てのフィルタ部A、B、Cが空調ユニット10内にあるため、清掃などのメンテナンスがしやすい。
また、室外空気導入路に熱交換気ユニット60と外気清浄フィルタ69を設けて、導入する室外空気を清浄し、吹出口を設けない、いわゆるダーティ―ゾーン(トイレ、洗面所等)から室外に通じる室内空気排出路から、部屋及び空間を空調した空気の一部とダーティ―ゾーンの空気を室外に排出することにより、清浄された室外空気を導入し、埃や水分で汚れた建物2内の空気を排出しながら、建物2内を換気できる。
さらに、建物2内で、人間が発生する水分以外で、入浴や調理により水分を発生する浴室80と台所等の空気は、室外へ排出する天井埋込型換気扇81を設けることにより、建物2内にそれらの水分が滞留せず、空調空気に含まれないため、空調送風路内にそれらの水分が流れこまない。
これらにより、空調送風路A30、空調送風路B31内に、埃や水分や結露水等が堆積、滞留しないので、カビも繁殖しにくく、雑菌による臭いも発生しにくく、建物2内に、空調送風路内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。そして、長期間使用しても、空調送風路の清掃などのメンテナンスが不要で、建物2内を常に健康で快適な空調換気を行うことが可能である。 As described above, the temperature of the air around the air-conditioning ventilation path A30 and the air-conditioning ventilation path B31 created by theair conditioning unit 10 provided with the suction unit, the air conditioning unit 20, and the air blowing unit 17 is within 5 K during cooling and within 5 K during heating. By blowing conditioned air within 10K into the conditioned air passage with a large air volume, it blows out from the air outlets 40, 41, 42 of the room A 23, room B 24, and the entrance 13, and the rooms in the building 2 with high airtightness and high heat insulation. Since the space is air-conditioned, the inside of the building 2, including the space with a large air-conditioning load such as a solar radiation load, tends to be comfortable and uniform in temperature and humidity. Since the air-conditioning duct is surrounded by an air-conditioned room, space, or heat insulating material, dew condensation inside and outside the air-conditioning duct during cooling and inside the air-conditioning duct during heating is less likely to occur.
In addition, the return air port filter 85 (filter section A) provided in the suction section of theair conditioning unit 10 that produces the conditioned air cleans all of the air that is sucked into the air conditioning unit 10, and the air that is sucked into the air conditioning section 20 is , the air-conditioning unit filter 86 (filter unit B), and the air-blowing unit filter 87 (filter unit C) of the plurality of air-blowing units 17 cleans all the air sucked into the air-conditioning unit 10 without omission. The air in the building 2 is cleaned by flowing into the path A30 and the air conditioning ventilation path B31, and the risk of dust, etc., which is one of the breeding conditions for mold, flowing into the air conditioning ventilation path is further reduced. , B, and C are in the air conditioning unit 10, maintenance such as cleaning is easy.
In addition, a heatexchange air unit 60 and an outdoor air cleaning filter 69 are provided in the outdoor air introduction path to purify the outdoor air to be introduced, and the so-called dirty zone (toilet, washroom, etc.) that does not have an air outlet is connected to the outside. By discharging part of the air that has conditioned the rooms and spaces and the air in the dirty zone to the outside from the indoor air discharge path, the cleaned outdoor air is introduced, and the air inside the building 2 that is contaminated with dust and moisture. The inside of the building 2 can be ventilated while discharging the .
Furthermore, the air in thebathroom 80 and the kitchen, etc., which generate moisture other than the moisture generated by humans in the building 2 due to bathing and cooking, can be eliminated by installing a ceiling-embedded ventilation fan 81 that exhausts the air to the outside of the building 2. Since the moisture does not stay in the air and is not contained in the conditioned air, the moisture does not flow into the conditioned air duct.
As a result, dust, moisture, condensed water, and the like do not accumulate or remain in the air-conditioning air passage A30 and the air-conditioning air passage B31. Dust, mold, bacteria, and odors from the road are less likely to enter, creating a healthy and comfortable space. And even if it is used for a long period of time, maintenance such as cleaning of the air-conditioning air passage is not required, and it is possible to always air-condition and ventilate the inside of thebuilding 2 in a healthy and comfortable manner.
また、空調空気を作り出す空調ユニット10の吸込部に設けた還気口フィルタ85(フィルタ部A)により、空調ユニット10に吸い込まれる空気の全てが清浄され、さらに空調部20に吸い込まれた空気は、空調部フィルタ86(フィルタ部B)でさらに清浄し、複数の送風部17の送風部フィルタ87(フィルタ部C)で、空調ユニット10に吸い込まれた空気の全てを漏れなく清浄し、空調送風路A30、空調送風路B31に流入させ、建物2内の空気を清浄し、空調送風路に、カビの繁殖条件の一つである埃等が流入するリスクがさらに減少し、全てのフィルタ部A、B、Cが空調ユニット10内にあるため、清掃などのメンテナンスがしやすい。
また、室外空気導入路に熱交換気ユニット60と外気清浄フィルタ69を設けて、導入する室外空気を清浄し、吹出口を設けない、いわゆるダーティ―ゾーン(トイレ、洗面所等)から室外に通じる室内空気排出路から、部屋及び空間を空調した空気の一部とダーティ―ゾーンの空気を室外に排出することにより、清浄された室外空気を導入し、埃や水分で汚れた建物2内の空気を排出しながら、建物2内を換気できる。
さらに、建物2内で、人間が発生する水分以外で、入浴や調理により水分を発生する浴室80と台所等の空気は、室外へ排出する天井埋込型換気扇81を設けることにより、建物2内にそれらの水分が滞留せず、空調空気に含まれないため、空調送風路内にそれらの水分が流れこまない。
これらにより、空調送風路A30、空調送風路B31内に、埃や水分や結露水等が堆積、滞留しないので、カビも繁殖しにくく、雑菌による臭いも発生しにくく、建物2内に、空調送風路内の埃やカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。そして、長期間使用しても、空調送風路の清掃などのメンテナンスが不要で、建物2内を常に健康で快適な空調換気を行うことが可能である。 As described above, the temperature of the air around the air-conditioning ventilation path A30 and the air-conditioning ventilation path B31 created by the

As a result, dust, moisture, condensed water, and the like do not accumulate or remain in the air-conditioning air passage A30 and the air-conditioning air passage B31. Dust, mold, bacteria, and odors from the road are less likely to enter, creating a healthy and comfortable space. And even if it is used for a long period of time, maintenance such as cleaning of the air-conditioning air passage is not required, and it is possible to always air-condition and ventilate the inside of the
また、空調ユニット10の送風部17により、還気口(吸込部)55から吸い込まれる空気の一部が、空調部20に吸い込まれ、空調され、吹き出される。そして、吸込部から吸い込まれた空気の一部が、空調部20に吸い込まれず、空調部20からの吹出空気と混合部95で合流し、混合され、空調部20の風量、設定温度、送風部17の風量等を調整して、空調送風路A30、空調送風路B31周囲の空気の温度に対し、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、その空調空気を空調送風路に通すので、空調送風路に結露しにくい。
さらに、空調部20の風量に対し、送風部17の風量が大幅に多く、部屋及び空間の温度に対しても、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、部屋及び空間の温度がオーバーシュートするなど大幅に変動せず、長時間安定して、空調部20の吸込空気の温度が、設定温度に近いため、特に夏季の冷房運転時は、空調部20は、小温度差でのサーモON状態が長時間継続し、圧縮機が低周波数で継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、冷房運転時、さらに空調送風路に結露しにくい。
さらに、送風部17の風量はゼロではなく、常に空調空気を流し続ける仕様としているので、空調送風路内に結露した場合でも、できる限り早く蒸発させることができる。 Also, part of the air sucked from the return air port (suction portion) 55 is sucked into theair conditioning unit 20 by the air blowing unit 17 of the air conditioning unit 10, air-conditioned, and blown out. Part of the air sucked from the suction unit is not sucked into the air conditioning unit 20, but joins with the air blown from the air conditioning unit 20 in the mixing unit 95 and mixed. By adjusting the air volume of 17, the temperature of the air around the air conditioning ventilation path A30 and the air conditioning ventilation path B31 is stabilized with a large air volume within 5K during cooling and within 10K during heating with energy saving. Since the conditioned air is passed through the air-conditioning air passage, dew condensation is unlikely to occur in the air-conditioning air passage.
Furthermore, the air volume of theair blowing unit 17 is significantly larger than the air volume of the air conditioning unit 20, and the temperature of the room and space is within 5 K during cooling and within 10 K during heating. , the temperature of the room and space does not fluctuate significantly such as overshooting, and the temperature of the air drawn into the air conditioning unit 20 is stable for a long time, and the temperature is close to the set temperature. During the cooling operation, the air conditioning unit 20 continues the thermo ON state with a small temperature difference for a long time, and the compressor continues to operate at a low frequency, so the surface temperature of the evaporator, the so-called evaporation temperature, When the temperature drops below the dew point temperature of the air, moisture in the air sucked in condenses on the evaporator. The absolute humidity of the room is also lowered, and the relative humidity of the air-conditioning air passage, the room, and the space through which the air-conditioned air flows is also lowered.
Furthermore, since the air volume of theair blowing section 17 is not zero, and the specifications are such that the conditioned air is always supplied, even if dew condensation occurs in the air conditioned air passage, it can be evaporated as quickly as possible.
さらに、空調部20の風量に対し、送風部17の風量が大幅に多く、部屋及び空間の温度に対しても、冷房時は5K以内、暖房時は10K以内の大風量の空調空気を、省エネで、安定して作り出すことができ、部屋及び空間の温度がオーバーシュートするなど大幅に変動せず、長時間安定して、空調部20の吸込空気の温度が、設定温度に近いため、特に夏季の冷房運転時は、空調部20は、小温度差でのサーモON状態が長時間継続し、圧縮機が低周波数で継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、冷房運転時、さらに空調送風路に結露しにくい。
さらに、送風部17の風量はゼロではなく、常に空調空気を流し続ける仕様としているので、空調送風路内に結露した場合でも、できる限り早く蒸発させることができる。 Also, part of the air sucked from the return air port (suction portion) 55 is sucked into the
Furthermore, the air volume of the
Furthermore, since the air volume of the
さらに、空調部20の圧縮機等を駆動させることにより、単位風量当たりのランニングコストが高い空調部20の風量よりも、単位風量当たりのランニングコストが大幅に低い送風部17の風量を多くして、空調空気を作り、空調送風路A30、空調送風路B31を通すシステムのため、省エネである。一例として、冷房能力4kW、COP4のエアコン(空調部)だけで、家全体に送風するための1200m3/hの空調空気を作り出すには、最低でも600m3/hのエアコンが2台必要で、能力制御してサーモOFFしないとすると合計約30~40円/hかかるが、エアコン(空調部)と送風機(送風部)で空調空気を作り出すには、エアコンを1台と200m3/hの送風機が6台必要で、能力制御してサーモOFFしないとすると、送風機はDCモーターで1台約5W/hの消費電力のため、合計でほぼエアコン1台分の約20円/hしかかからないと推定される。一般的に、エアコンのファンは貫流ファンのため、静圧が低く、ダクトで送風することはできないので、家の間取りにもよるが、エアコン2台で家全体に空調空気を送風することは困難で、実際には、さらに多くのエアコンが必要となり、ランニングコストはさらに高くなる。一方、送風機は軸流ファンのため、静圧が高く、空調送風路など風速が早くなる比較的断面積が狭い風路を送風するのに適しているので、エアコン1台で空調空気を作り出すことができ、ランニングコストは低くなる。
さらに、空調空気が流れる空調送風路が、2階建て以上の住宅では通常構造上必然的に区画され、存在する1階と2階の間の階間34に設けられ、空調送風路の表面積の多くを占める上下面を空調された部屋、空間に囲まれるので、わざわざ断熱材で囲う必要がなく、前後左右は、外壁に設けられた断熱材等に囲まれるので、空調送風路の結露がさらに発生しにくく、空調送風路の空調空気の入口から吹出口までの熱損失が少ない高効率な空調換気が行える。
さらに、空調ユニット10と空調送風路が直接繋がっており、階間34に設けられた空調送風路B31の上下に吹出口40、41、42を設け、1階の天井32と2階の床33から空調空気を吹き出して、部屋や空間を空調するので、空調ユニット10から吹出口40~42までの送風路が、最短距離で略真直ぐであり、途中の圧力損失が少ない、熱損失も少ない、省施工で合理的な構造の空調換気が行える。 Further, by driving the compressor or the like of theair conditioning unit 20, the air volume of the air blowing unit 17 whose running cost per unit air volume is significantly lower than the air volume of the air conditioning unit 20 whose running cost per unit air volume is high is increased. , air-conditioning air is generated and passed through the air-conditioning air passage A30 and the air-conditioning air passage B31, which saves energy. As an example, in order to create 1200 m 3 /h of conditioned air for blowing air to the entire house with only an air conditioner (air conditioning unit) with a cooling capacity of 4 kW and a COP of 4, at least two air conditioners with a capacity of 600 m 3 /h are required. If the capacity is controlled and the thermostat is not turned off, the total cost is about 30 to 40 yen/h, but in order to create conditioned air with an air conditioner (air conditioning unit) and a blower (blower unit), one air conditioner and a 200 m 3 /h blower are required. 6 units are required, and if the capacity is controlled and the thermostat is not turned off, the fan is a DC motor and consumes about 5 W/h of power, so it is estimated that the total cost will be only about 20 yen/h, which is almost the same as one air conditioner. be done. In general, the air conditioner fan is a cross-flow fan, so the static pressure is low and it is not possible to blow air with a duct. So, in reality, more air conditioners are needed, and running costs are even higher. On the other hand, since the blower is an axial fan, it has high static pressure and is suitable for air passages with a relatively narrow cross-sectional area, such as air conditioning passages, where the wind speed is high. and lower running costs.
Furthermore, the air-conditioning air duct through which air-conditioned air flows is inevitably divided structurally in a two-story house or more, and is provided in thespace 34 between the existing first and second floors, and the surface area of the air-conditioning air duct is increased. Since the upper and lower surfaces, which account for most of the space, are surrounded by air-conditioned rooms and spaces, there is no need to enclose them with heat insulating materials. Highly efficient air conditioning and ventilation can be performed with less heat loss from the air conditioning air inlet to the air outlet of the air conditioning air passage.
Furthermore, the air-conditioning unit 10 and the air-conditioning air passage are directly connected. Since the conditioned air is blown out from the air conditioning unit 10 to air-condition the room or space, the air passage from the air conditioning unit 10 to the outlets 40 to 42 is almost straight at the shortest distance, and the pressure loss on the way and the heat loss are also small. Air-conditioning ventilation with a rational structure can be performed with less construction work.
さらに、空調空気が流れる空調送風路が、2階建て以上の住宅では通常構造上必然的に区画され、存在する1階と2階の間の階間34に設けられ、空調送風路の表面積の多くを占める上下面を空調された部屋、空間に囲まれるので、わざわざ断熱材で囲う必要がなく、前後左右は、外壁に設けられた断熱材等に囲まれるので、空調送風路の結露がさらに発生しにくく、空調送風路の空調空気の入口から吹出口までの熱損失が少ない高効率な空調換気が行える。
さらに、空調ユニット10と空調送風路が直接繋がっており、階間34に設けられた空調送風路B31の上下に吹出口40、41、42を設け、1階の天井32と2階の床33から空調空気を吹き出して、部屋や空間を空調するので、空調ユニット10から吹出口40~42までの送風路が、最短距離で略真直ぐであり、途中の圧力損失が少ない、熱損失も少ない、省施工で合理的な構造の空調換気が行える。 Further, by driving the compressor or the like of the

Furthermore, the air-
さらに、再熱除湿運転時、一方の熱交換器91が低温低圧の冷媒が流れる蒸発器として、もう一方の熱交換器92が中温中圧の冷媒が流れる再熱器として機能するため、吸込空気の温度以上で、絶対湿度の低い吹出空気となり、吹出口97から吹き出されることにより、空調部20は、再熱除湿サーモON状態が長時間継続し、圧縮機が継続して運転するので、蒸発器の表面温度、いわゆる蒸発温度が、吸込空気の露点温度以下となって、蒸発器に吸込空気の水分が結露し、長時間運転により、除去される除湿量が多くなり、長時間継続して吹出空気の絶対湿度が低下し、空調空気の絶対湿度も低下し、その空調空気が流れる空調送風路内、部屋、空間の相対湿度も低下し、梅雨時期など中温高湿時等で、さらに空調送風路A30、空調送風路B31に結露しにくい。
さらに、循環路又は空調ユニット10にHEPAフィルタ式又は、電気集塵式の空気清浄機90を設け、空調空気に含まれるカビ胞子レベルの粒子も除去するため、空調空気が通る空調送風路A30、空調送風路B31内にカビがより繁殖しにくく、建物2内に、空調送風路内のカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。 Furthermore, during reheat dehumidification operation, oneheat exchanger 91 functions as an evaporator through which a low-temperature, low-pressure refrigerant flows, and the other heat exchanger 92 functions as a reheater through which medium-temperature, medium-pressure refrigerant flows. above the temperature, the blown air has a low absolute humidity and is blown out from the blowout port 97, so that the reheat dehumidification thermostat is kept ON for a long time, and the compressor continues to operate. The surface temperature of the evaporator, the so-called evaporation temperature, becomes lower than the dew point temperature of the intake air, and the moisture of the intake air condenses on the evaporator. As a result, the absolute humidity of the blown air decreases, the absolute humidity of the air-conditioned air also decreases, and the relative humidity of the air-conditioned air passages, rooms, and spaces in which the air-conditioned air flows also decreases. Condensation is less likely to occur on the air-conditioning air passage A30 and the air-conditioning air passage B31.
Furthermore, anair purifier 90 of HEPA filter type or electric dust collection type is provided in the circulation path or air conditioning unit 10, and in order to remove mold spore level particles contained in the conditioned air, the conditioned air passage A30 through which the conditioned air passes, Mold is less likely to propagate in the air-conditioning air duct B31, and mold, bacteria, odors, etc. in the air-conditioning air duct B31 are less likely to enter the building 2, and a healthy and comfortable space can be realized.
さらに、循環路又は空調ユニット10にHEPAフィルタ式又は、電気集塵式の空気清浄機90を設け、空調空気に含まれるカビ胞子レベルの粒子も除去するため、空調空気が通る空調送風路A30、空調送風路B31内にカビがより繁殖しにくく、建物2内に、空調送風路内のカビ、細菌、異臭などが入りにくく、健康で快適な空間を実現できる。 Furthermore, during reheat dehumidification operation, one
