Description

本発明は、高断熱・高気密木造家屋の集中空調に適した空調システムに関する。   The present invention relates to an air conditioning system suitable for centralized air conditioning in a highly insulated and airtight wooden house.

従来、戸建住宅では、各部屋に空調機を設置して、それぞれ別個に空調が行われるのが一般的であった。これらの空調機は、部屋の大きさに応じて標準仕様の6畳用や8畳用などの表示に従って設置されているが、短時間で所定の温度に出来るように必要な熱交換容量に比べて過大な冷暖房能力を備え、エネルギー消費が大きいという問題があった。一方、主に寒冷地において、暖房費の節減等を目的として戸建住宅の高断熱高気密化が図られ、それに伴って、戸建住宅でも集中空調システムが検討されてきており、例えば、特許文献1には、予め所定の温度、湿度などに調和された空気を建物内の一箇所で生成し、これを建物内に循環させる空気搬送式の集中空調装置が提案されている。   Conventionally, in a detached house, it is common to install an air conditioner in each room and perform air conditioning separately. These air conditioners are installed according to the standard specifications for 6 tatami mats and 8 tatami mats according to the size of the room, but compared to the heat exchange capacity necessary to achieve a predetermined temperature in a short time In addition, there is a problem that it has an excessive cooling and heating capacity and large energy consumption. On the other hand, mainly in cold districts, high insulation and high airtightness of detached houses has been achieved for the purpose of reducing heating costs, etc. Document 1 proposes an air-conveying centralized air conditioner that generates air harmonized with a predetermined temperature, humidity, and the like in one place in a building and circulates the air in the building.

図2は、従来の空調システムの例であり、空気搬送式集中空調装置80が設置された寒冷地用住宅建物90が示されている。建物90は、一階および二階に複数の居室91を有している。集中空調装置80は、集中空調ユニット81を有し、吸い込んだ空気を熱交換器82で加熱し、ダクト83を通して各居室91へ送る。ダクト83の各居室91に開口する部分にはダンパ84が設置され、ルームコントローラ85により開度調整され、居室内をそれぞれ所定温度に維持するようになっている。   FIG. 2 is an example of a conventional air conditioning system, and shows a residential building 90 for cold districts where an air-conveying central air conditioning apparatus 80 is installed. The building 90 has a plurality of living rooms 91 on the first and second floors. The central air conditioner 80 has a central air conditioning unit 81, heats the sucked air with a heat exchanger 82, and sends it to each living room 91 through a duct 83. A damper 84 is installed in a portion of the duct 83 that opens to each room 91, and the opening degree is adjusted by the room controller 85 so that each room is maintained at a predetermined temperature.

一方、各室91へ送られた空気は順次ドア92から通路を通り、階段ホール93に集合する。その一部は集中空調ユニット81へ回収され、再びダクト83により各居室へ送られる。また、階段ホール93に設けられた全熱交換換気装置51により一部の空気が換気される。全熱交換換気装置51は、室内側吸気口52と屋外側排気口53とが内気排出経路を形成し、屋外側吸気口54と室内側排気口55が外気吸入経路を形成し、これらが互いに熱交換が行うように構成されている。   On the other hand, the air sent to each chamber 91 sequentially passes through the passage from the door 92 and gathers in the staircase hole 93. A part of it is collected in the central air conditioning unit 81 and sent again to each room by a duct 83. A part of the air is ventilated by the total heat exchange ventilator 51 provided in the staircase hole 93. In the total heat exchanging ventilator 51, the indoor side intake port 52 and the outdoor side exhaust port 53 form an inside air discharge path, and the outdoor side intake port 54 and the indoor side exhaust port 55 form an outside air intake path, which are mutually connected. It is configured to perform heat exchange.

しかしながら、このような集中空調システムでは、ダクトの分岐により、空調された空気が分散されるため、各居室への分岐経路に対する空調能力が低くなり、特に空調装置の設置箇所から離れた位置にある居室は所望の温度に達するまでに時間がかかるという問題があった。   However, in such a centralized air conditioning system, air conditioned air is dispersed by the branching of the ducts, so the air conditioning capacity for the branch path to each living room is low, especially at a position away from the location where the air conditioner is installed. There was a problem that it took time for the living room to reach the desired temperature.

またこのような高断熱・高気密住宅における集中空調システムは、主に寒冷地における暖房の利用を想定しており、室内温度の方が外気温よりも高い状況において、居室に送られた空気は主に循環させ、一部のみを排気して導入する外気の量を抑えることによって暖房効率を高めている。しかしながら、温暖な地域においては、高断熱・高気密住宅では、夏季に室内温度の方が外気温よりも高くなる状況が生じるため、屋内で空気を循環させると、空調開始時に所望の温度に冷房するまでに時間を要する。   In addition, the centralized air conditioning system in such highly insulated and airtight houses mainly assumes the use of heating in cold districts, and the air sent to the room in the situation where the room temperature is higher than the outside temperature is Heating efficiency is increased by reducing the amount of outside air that is mainly circulated and exhausted only partly. However, in a warm area, in a highly insulated and airtight house, the indoor temperature may be higher than the outdoor temperature in the summer, so if the air is circulated indoors, it will be cooled to the desired temperature at the start of air conditioning. It takes time to do.

さらに、高断熱・高気密住宅では、基本的に各居室の気密性が高く換気がされにくいところ、この集中空調システムでは、各居室の排気はドアを通じて、建物全体の空気循環の中で行われるだけであるので、閉じられた特定の居室内の空調維持が困難で、空気が汚染され、急に換気が必要となった場合に対応できないという問題があった。   Furthermore, in highly insulated and airtight houses, each room is basically airtight and difficult to ventilate. In this centralized air conditioning system, each room is exhausted through the door in the air circulation of the entire building. Therefore, there is a problem that it is difficult to maintain air conditioning in a specific closed room, the air is contaminated, and sudden ventilation is required.

特開平7−190414号公報Japanese Patent Laid-Open No. 7-190414

本発明の目的は、高断熱・高気密住宅において、空調機の設置箇所からの距離にかかわらず各居室を速やかに空調するとともに、各居室を迅速に換気することができ、特に温暖な地域において速やかに効率よく冷房することが可能な空調システムを提供することにある。   The purpose of the present invention is to quickly air-condition each room regardless of the distance from the location of the air conditioner in a highly insulated and air-tight house, and to quickly ventilate each room, especially in warm areas. An object of the present invention is to provide an air conditioning system capable of quickly and efficiently cooling.

上記課題を解決した本発明の空調システムは、複数個の居室を備えた高断熱・高気密木造家屋において、少なくともひとつの空調機を配置した空調室を居室から独立して設けるとともに、空調室と各居室を連結する給気ダクトとを備え、屋外から給気される空気を空調機により空調し、空調された空調室内の空気を各居室に給気ダクトを介して個別的に分配給気し、各居室を空調する空調システムであって、空調室における各給気ダクトの入口に各居室から独立制御可能な直流ファンを設けるとともに、各居室毎に各給気ダクトの出口に連通する給気口と排気口を別々に備え、両者の給排気により各居室内の換気と空調を同時に行う構成としている。   The air conditioning system of the present invention that has solved the above problems is a highly insulated and airtight wooden house having a plurality of living rooms, and is provided with an air conditioning room in which at least one air conditioner is arranged independently from the living room, Air supply ducts connecting each living room, air supplied from outside is air-conditioned by an air conditioner, and the air in the air-conditioned room is individually distributed and supplied to each living room via the air supply duct An air conditioning system that air-conditions each living room, and a DC fan that can be independently controlled from each room is provided at the inlet of each air supply duct in the air-conditioning room, and the air supply that communicates with the outlet of each air supply duct for each room It has a configuration in which a mouth and an exhaust port are provided separately, and ventilation and air conditioning in each room are performed simultaneously by supplying and exhausting both.

また本発明の空調システムは、空調室と各居室を連結する給気ダクトが、清掃手段が入出可能な内径を有する断熱性可撓管からなるものである。   In the air conditioning system of the present invention, the air supply duct connecting the air conditioning room and each living room is composed of a heat-insulating flexible tube having an inner diameter through which the cleaning means can enter and exit.

また本発明の空調システムは、各居室の排気口から集められた排気が、屋外からの吸気と熱交換して屋外に排出される構成としている。   Moreover, the air conditioning system of this invention is set as the structure by which the exhaust_gas | exhaustion collected from the exhaust port of each room is heat-exchanged with the intake air from the outdoors, and is discharged | emitted outdoors.

本発明の空調システムは、高断熱・高気密住宅において、空調機の設置箇所から離れた居室であっても速やかに空調することができ、また各居室を個別に迅速に換気することが可能である。特に温暖な地域においても、立ち上がり時に効率よく速やかに所望の温度に冷房することができる。   The air-conditioning system of the present invention can quickly air-condition even a living room away from the location of the air conditioner in a highly insulated and highly airtight house, and can individually ventilate each room quickly. is there. In particular, even in a warm region, it can be quickly and efficiently cooled to a desired temperature at the time of startup.

以下、本発明の空調システムの実施態様を、図面に基づいて具体的に説明する。なお、本発明はこれら実施態様に何ら制約されるものではない。   Hereinafter, embodiments of the air conditioning system of the present invention will be specifically described with reference to the drawings. Note that the present invention is not limited to these embodiments.

図1には、本発明の空調システムを適用した高断熱・高気密木造家屋30が示されている。家屋30は、被空調区画である複数の居室31を有する二階建ての住宅であり、高断熱・高気密化されている。ここで、高断熱・高気密木造家屋とは、熱損失係数Q値が、地域毎の次世代省エネルギー基準(平成11年)の基準値を満足するものをいう。   FIG. 1 shows a highly insulated and airtight wooden house 30 to which the air conditioning system of the present invention is applied. The house 30 is a two-story house having a plurality of living rooms 31 which are air-conditioned sections, and is highly insulated and airtight. Here, the high heat insulation and high airtight wooden house means that the heat loss coefficient Q value satisfies the standard value of the next generation energy saving standard (1999) for each region.

2階には、居室31とは独立して空調室32が設けられ、ここには家屋30内の全館空調を行える空調能力を備えた一台の空調機1が備えられている。空調機1は、吸い込んだ空気の温度を調整して吐出する機能を有しており、必要に応じ、除湿や加湿を行う湿度調整機能、塵埃を集める集塵機能等を備えていても良い。   On the second floor, an air-conditioning room 32 is provided independently of the living room 31, and a single air conditioner 1 having air-conditioning capability capable of air-conditioning the entire building in the house 30 is provided here. The air conditioner 1 has a function of adjusting and discharging the temperature of the sucked air, and may have a humidity adjusting function for dehumidifying and humidifying, a dust collecting function for collecting dust, and the like as necessary.

空調室32と各居室31とは、それぞれ個別の給気ダクト10により連結されている。給気ダクト10は、清掃手段が入出可能な内径を有する断熱性可撓管からなる。清掃手段としては、例えば、150mmφ程度の煙突掃除用ワイヤーブラシ等が例示される。給気ダクト10は、1階の各居室31の天井裏空間および2階の各居室31の床下空間により形成される空間33に配設されている。   The air conditioning room 32 and each living room 31 are connected to each other by individual air supply ducts 10. The air supply duct 10 is formed of a heat insulating flexible tube having an inner diameter through which the cleaning means can enter and exit. Examples of the cleaning means include a chimney cleaning wire brush of about 150 mmφ. The air supply duct 10 is disposed in a space 33 formed by a ceiling space of each living room 31 on the first floor and an underfloor space of each living room 31 on the second floor.

空調室32における各給気ダクト10の入口には、各居室31から独立制御可能な直流ファン10aが設けられており、各居室31に設けられたコントローラーにより、各居室31へ供給する空調された空気の風量を調整することができる。一方、各居室31には、各給気ダクト10の出口と連通する給気口10bが設けられている。   A DC fan 10a that can be independently controlled from each room 31 is provided at the entrance of each air supply duct 10 in the air-conditioning room 32. The controller provided in each room 31 is air-conditioned to be supplied to each room 31. The air volume can be adjusted. On the other hand, each room 31 is provided with an air supply port 10 b communicating with the outlet of each air supply duct 10.

屋外から給気される空気は、空調機1により空調され、空調された空調室32内の空気は、給気ダクト10を介して各居室31へ個別的に分配される。空調室32内の各給気ダクト10の入口に設けられた直流ファンにより、各居室31への空気の供給量を個別に制御している。   Air supplied from the outside is air-conditioned by the air conditioner 1, and the air in the air-conditioned room 32 is individually distributed to each living room 31 through the air supply duct 10. The amount of air supplied to each room 31 is individually controlled by a direct current fan provided at the inlet of each air supply duct 10 in the air conditioning room 32.

一方、各居室31には排気口20aが給気口10bとは別に備えられており、排気口20aにも直流ファンが設けられている。排気口20aの直流ファンも各居室31に備えられたコントローラーにより独立制御可能となっている。各居室31の排気口20aには、排気ダクト20が連結されており、これらは各階の天井裏空間等に配設され、2階に設けられた中間ダクトファン3に集約される。1本に集約されたダクト21は熱交換機2に連結している。   On the other hand, each living room 31 is provided with an exhaust port 20a separately from the air supply port 10b, and a DC fan is also provided in the exhaust port 20a. The DC fan at the exhaust port 20a can also be independently controlled by a controller provided in each room 31. The exhaust duct 20 is connected to the exhaust port 20a of each living room 31, and these are arranged in the ceiling back space etc. of each floor, and are collected by the intermediate duct fan 3 provided on the second floor. A single duct 21 is connected to the heat exchanger 2.

各居室31へ送られた空気は、排気口20aから排気ダクト20を通り中間ダクトファン3を経て集約され、熱交換器2において、ダクト12より屋外から導入された外気と熱交換した後、ダクト22により屋外へ排気される。一方、導入された外気は熱交換後ダクト11より空調機1に入り空調され、給気ダクト10により各居室31へ供給される。   The air sent to each room 31 is collected from the exhaust port 20a through the exhaust duct 20 and through the intermediate duct fan 3, and in the heat exchanger 2, after exchanging heat with the outside air introduced from the outside through the duct 12, 22 is exhausted to the outdoors. On the other hand, the introduced outside air enters the air conditioner 1 from the duct 11 after heat exchange, is air-conditioned, and is supplied to each living room 31 by the air supply duct 10.

このように、本発明の空調システムでは、空調室32と各居室31は分岐のない1本の給気ダクト10で連結されており、また空調室32の直流ファン10aと各居室31の排気口20aの直流ファンとにより空気の循環が促されるため、距離が長い給気ダクトであっても空調された空気が速やかに搬送され、空調室32から距離が離れた居室31においても所望の温度に早期に到達し得る。   Thus, in the air conditioning system of the present invention, the air conditioning chamber 32 and each living room 31 are connected by the single air supply duct 10 without branching, and the DC fan 10a of the air conditioning room 32 and the exhaust port of each living room 31 are connected. Since the circulation of air is promoted by the DC fan 20a, the air-conditioned air is promptly transported even in a long-distance supply duct, and the desired temperature is also obtained in the living room 31 that is far from the air-conditioning room 32. Can reach early.

また、各居室31に個別に制御可能な直流ファンを備えた排気口20aが設けられているため、特定の居室31で急いで換気を行う必要が生じた場合にも、迅速に室内の汚れた空気を排気し、新鮮な外気を導入することができる。   In addition, since each room 31 is provided with an exhaust port 20a equipped with a DC fan that can be individually controlled, even if it is necessary to ventilate quickly in a specific room 31, the room is quickly soiled. Air can be exhausted and fresh outside air can be introduced.

さらに、温暖な地域で屋内よりも外気温の方が低い状況において、本発明の空調システムでは、各居室31の排気口20aから排気ダクト20に入った空気は、再び屋内で循環することなく全て排気され、これに相当する量の温度の低い外気が導入されるため、立ち上がり時に効率よく速やかに冷房できる。   Further, in a situation where the outside air temperature is lower than indoors in a warm region, in the air conditioning system of the present invention, all the air that has entered the exhaust duct 20 from the exhaust port 20a of each living room 31 does not circulate indoors again. Since it is exhausted and a corresponding amount of low temperature outside air is introduced, it can be efficiently and quickly cooled at the time of startup.

実施例1
宮崎県日向市に設置した高断熱高気密住宅において集中空調システムによる冷房を実施した。当該住宅は、地域区分「V」における省エネルギー対策等級「4」の性能の2倍に相当する高断熱高気密性能を備えたものであり(国土交通省住宅局住宅生産課監修、「新築住宅の住宅性能表示制度ガイド」、14ページ)、建坪は129.38m、2階建で居室数6(居室全体の気積405.86m)、空調室1を有している。空調システムは、空調室に2.8Kwの空調機を1台備え、空調室から各居室間を直流ファン付150mm給気ダクトで接続している。同様に各居室から中間ダクト間も直流ファン付150mm排気ダクトで接続しており、換気量は1時間に1/2回である。各居室からの排気は、熱交換器(熱交換効率70%)を通して熱交換し屋外に排気される。
Example 1
The central air conditioning system was used for air conditioning in a highly insulated and airtight house in Hyuga City, Miyazaki Prefecture. The house has high thermal insulation and airtightness equivalent to twice the performance of the energy conservation measure class “4” in the region classification “V” (supervised by the Housing Production Division, Ministry of Land, Infrastructure, Transport and Tourism, “ “Housing Performance Display System Guide”, page 14), the floor area is 129.38 m 2 , the number of rooms is 6 (the volume of the entire room is 405.86 m 3 ), and the air conditioning room 1 is provided. The air conditioning system is provided with one 2.8 Kw air conditioner in the air conditioning room, and each room is connected from the air conditioning room by a 150 mm air supply duct with a DC fan. Similarly, each room is connected to the intermediate duct by a 150 mm exhaust duct with a DC fan, and the ventilation volume is ½ times per hour. Exhaust air from each room is exchanged through the heat exchanger (heat exchange efficiency 70%) and exhausted outdoors.

8月下旬の真夏日において、空調室の温度を23度に設定して、空調機及びダクトファンを終日運転した。居室内の目標温度は25度とした。空調室からの距離が異なる各居室の室温を測定した。送気用ファンの回転数は高速および中速の2段階で制御した。測定は、6時から22時まで1時間ごとに行った。参考として、測定時刻における外気温と空調室温度を測定した。測定結果を表1に示す。表1には、ダクト長で表示した空調室から各居室までの距離および居室の日照条件を併せて記載した。また、空調室から各居室までの距離が最も長い居室11における室内温度の変化を図3に示した。
On the midsummer day in late August, the temperature of the air conditioning room was set to 23 degrees, and the air conditioner and duct fan were operated all day. The target temperature in the room was 25 degrees. The room temperature of each room with different distance from the air-conditioned room was measured. The rotation speed of the air supply fan was controlled in two stages, high speed and medium speed. The measurement was performed every hour from 6 o'clock to 22 o'clock. As a reference, the outside air temperature and the air conditioning room temperature at the measurement time were measured. The measurement results are shown in Table 1. In Table 1, the distance from the air-conditioned room indicated by the duct length to each room and the sunshine conditions of the room are also shown. Moreover, the change of the room temperature in the living room 11 with the longest distance from the air-conditioned room to each living room is shown in FIG.

表1から明らかなように、一日の外気温の時間推移にともない、空調室で23℃に制御していても、空調室から遠い居室11、12、13で室温を25℃に保つにはファンの回転数は高速回転にする必要があるが、空調室に近い居室21、22、23ではファンの回転数は中回転ですむ。仮に、ファンの回転数を居室から制御できなければ、空調室からの距離長に依存して室温が上昇することは避けられない。本発明では、ファンの回転数を居室からダクト毎に独立制御できるようにすることにより、各居室を略同一標準温度に簡単に制御できる。加えて、居住者の体調、嗜好に応じて、あたかも各居室に空調機を設置しているのと同じように室温を居室毎に独立調節できる。   As is clear from Table 1, the room temperature is kept at 25 ° C. in the living rooms 11, 12, 13 far from the air-conditioning room even if the temperature is controlled at 23 ° C. in the air-conditioning room as the daily outside air temperature changes over time. Although it is necessary to make the rotation speed of a fan high-speed rotation, in the living rooms 21, 22, and 23 near an air-conditioning room, the rotation speed of a fan only needs medium rotation. If the rotation speed of the fan cannot be controlled from the room, it is inevitable that the room temperature will rise depending on the distance from the air conditioning room. In the present invention, each room can be easily controlled to substantially the same standard temperature by enabling independent control of the rotation speed of the fan for each duct from the room. In addition, according to the physical condition and preference of the resident, the room temperature can be independently adjusted for each room as if an air conditioner is installed in each room.

空調室から各居室までの距離が最も長い居室11について、より詳細に温度変化を見てみると、図3より、朝の6時の時点では、建物内部全体が25度付近で維持されており、その後急激に外気温度が上昇しても、空調室の設定温度23度をそのままとした冷房能力の範囲内で、送気ファンを高速回転にするだけで十分に居室内温度を調節することができた。これは、気温が急激に上昇しているときにおいても、建物内部全体が持っている熱容量が大きいためと考えられる。   Looking at the temperature change in room 11 with the longest distance from the air-conditioned room to each room, it can be seen from FIG. 3 that the entire interior of the building is maintained at around 25 degrees at 6 o'clock in the morning. Then, even if the outside air temperature rises suddenly, the room temperature can be adjusted sufficiently by simply rotating the air supply fan at a high speed within the cooling capacity range of the air conditioning room set temperature of 23 degrees. did it. This is considered to be because the heat capacity of the entire building is large even when the temperature is rising rapidly.

午後になると直射熱や断熱材を通して、屋根や壁面からの入熱で建物内部全体の温度が上昇する。午後の後半に、やや負荷がかかり、17〜18時の2時間ほど、室温が目標温度から1度上昇したが、19時から目標温度に戻った。終日、空調機を運転継続するが、夜間は熱負荷が次第に低くなり、部屋の壁からの冷却効果で建物内部全体を冷却し、翌朝までには建物全体が25度の設定温度付近になっていた。   In the afternoon, the temperature inside the building rises due to heat input from the roof and walls through direct heat and insulation. In the second half of the afternoon, a little load was applied, and the room temperature rose once from the target temperature for 2 hours from 17 to 18 o'clock, but returned to the target temperature from 19:00. The air conditioner continues to run all day, but the heat load gradually decreases at night, and the entire building is cooled by the cooling effect from the walls of the room. By the next morning, the entire building is close to the set temperature of 25 degrees. It was.

また図3より、居室内温度と外気温度との差が最大となる正午前後よりも夕方に熱負荷のピークがあることが示された。建物の熱容量の効果により正午頃までは熱負荷が緩和されるが、夕方に日射熱の蓄積により建物内部が暖まってくるためと考えられる。外気温度による熱負荷が更に大きくなった際においても、空調機の冷房能力にはまだ余裕があるため、空調室の設定温度を下げることにより各居室内の温度を目標温度に維持することが容易である。建物の高断熱、遮熱、高気密性による効果に加え、建物内部の熱容量がある大きさを持つため、入熱を平均化することとなり、1台の空調機を連続稼動し、空調室からの距離に応じてファンの回転数を設定することにより、各室内を快適温度に保ちながら、かつ省エネを達成できた。   Further, FIG. 3 shows that there is a peak of heat load in the evening rather than after noon when the difference between the room temperature and the outside air temperature becomes maximum. The heat load is alleviated until noon due to the effect of the heat capacity of the building, but it is thought that the interior of the building warms up due to the accumulation of solar heat in the evening. Even when the heat load due to the outside air temperature further increases, the cooling capacity of the air conditioner is still sufficient, so it is easy to maintain the temperature in each room at the target temperature by lowering the set temperature of the air conditioning room It is. In addition to the effects of high thermal insulation, heat insulation and high airtightness of the building, the heat capacity inside the building has a certain size, so the heat input will be averaged, and one air conditioner will be operated continuously, By setting the number of fan rotations according to the distance, energy was saved while maintaining a comfortable temperature in each room.
