Description

本発明は、空調システムに関する。   The present invention relates to an air conditioning system.

空調システムの一つである住宅のセントラル空調システム(ダクト式全館空調システム)は、高気密・高断熱住宅に多く採用されている。しかし、空調面積の増加、運転時間の増加により、個別の空調機であるエアー・コンディショナー(エアコン)方式に比べ、エネルギー消費量が増大する傾向にある。特に複数の部屋を有する住宅では、各部屋の方位が異なるため、部屋毎に日射時間に差が出る関係で、室内温度にも差を生じる。   The residential central air conditioning system (duct type air conditioning system), which is one of the air conditioning systems, is widely used in highly airtight and highly insulated houses. However, as the air conditioning area increases and the operation time increases, the energy consumption tends to increase as compared to the air conditioner (air conditioner) system that is an individual air conditioner. In particular, in a house having a plurality of rooms, since the orientations of the rooms are different, there is a difference in the room temperature due to the difference in the solar radiation time for each room.

一方、これまでのセントラル空調システムでは、送風機が一台で定風量であったため、各部屋の風量制御が難しく、結果的に不要な空調、過暖房、過冷房による快適性の低下を招来する虞がある。
したがって、現状のセントラル空調システムでは、高気密・高断熱住宅の優れた熱的性能を生かしきれていない。
On the other hand, in conventional central air conditioning systems, since a single fan has a constant air volume, it is difficult to control the air volume in each room, resulting in a decrease in comfort due to unnecessary air conditioning, overheating, and overcooling. There is.
Therefore, the current central air-conditioning system cannot take full advantage of the excellent thermal performance of highly airtight and highly insulated houses.

そこで、部屋毎に配管されたダクトのそれぞれに送風機を設置した技術が、例えば特許文献1に開示されている。
特許文献1に開示の技術では、ダクト毎に設置された送風機の回転速度を変えることで、各部屋に吹き出される風量を調整するようになっており、これにより各部屋の空調を実施するようになっている。
Therefore, for example, Patent Document 1 discloses a technique in which a blower is installed in each duct piped for each room.
In the technique disclosed in Patent Document 1, the amount of air blown into each room is adjusted by changing the rotation speed of the blower installed for each duct, and thereby air conditioning of each room is performed. It has become.

特開平10−325565号公報Japanese Patent Laid-Open No. 10-325565

しかしながら、前記特許文献1の技術では、日照時間その他の外部環境の影響を受けることに基づいた各部屋間の温度差である室間温度差の考察がされていない。
このため、各部屋、及び住宅全体としての快適性に支障を生じ、さらにはエネルギー消費も大きいという問題があった。
また、空調機室内の目標温度と、空調対象の部屋の目標温度との差によって、居住者が不快になる温度差というものを解消したいという要望があった。
However, the technique of Patent Document 1 does not consider the temperature difference between the rooms, which is the temperature difference between the rooms based on the influence of the sunshine time and other external environments.
For this reason, there is a problem that the comfort of each room and the entire house is hindered and the energy consumption is also large.
In addition, there has been a desire to eliminate the temperature difference that makes residents uncomfortable due to the difference between the target temperature in the air conditioner room and the target temperature in the air-conditioned room.

本発明は、このような技術的背景を考慮してなされたもので、少なくとも日照時間その他の外部環境の影響を受けても室間温度差を少なくすることができる技術の提供をすることを課題とする。   The present invention has been made in consideration of such a technical background, and it is an object of the present invention to provide a technique capable of reducing the temperature difference between rooms even at least under the influence of sunlight time and other external environments. And

上記した技術的課題を解決するため、本発明では以下の構成とした。
すなわち、本発明は、本発明は、空調機室内の空調を行う空調機と、一方の口が前記空調機室を基点になるようにされ、他方の口が住宅の複数のそれぞれの部屋に導かれて配管
された複数のそれぞれのダクトと、前記複数のそれぞれのダクトの前記空調機室側の口に対して設けられた複数の送風機とを備え、前記空調機室内の目標温度と、空調対象の部屋の目標温度が、立ち上がり時を除き冷房時摂氏5度以内の温度差、暖房時摂氏10度以内の温度差で空調させる空調システムでもある。
In order to solve the above technical problem, the present invention has the following configuration.
That is, the present invention relates to an air conditioner that performs air conditioning in an air conditioner room, and one opening is set as a base point of the air conditioner room, and the other opening is led to a plurality of rooms in a house. Each of the plurality of ducts that are piped and a plurality of blowers provided to the air conditioner room side mouths of the plurality of ducts, the target temperature in the air conditioner room, and the air conditioning target The air conditioning system is configured to air-condition the room with a temperature difference within 5 degrees Celsius during cooling and a temperature difference within 10 degrees Celsius during heating, except when starting up.

このように構成された本発明の空調システムによれば、空調機室内の目標温度と、空調対象の部屋の目標温度とが、冷房時摂氏5度以内の温度差、暖房時摂氏10度以内の温度差で空調されるので、日照時間その他の外部環境の影響を受けても室間温度差を少なくすることができる。よって、省エネルギー型の送風システムということができる。   According to the air conditioning system of the present invention configured as described above, the target temperature in the air conditioner room and the target temperature in the room to be air-conditioned are within a temperature difference of 5 degrees Celsius during cooling and within 10 degrees Celsius during heating. Since the air conditioning is performed with the temperature difference, the temperature difference between the rooms can be reduced even under the influence of the sunshine time and other external environment. Therefore, it can be said that it is an energy-saving air blowing system.

また、空調機室と部屋の温度差を冷房時摂氏5度以内、暖房時摂氏10度以内とすることにより、ダクトから各部屋に排出される空気が部屋に居住する人に向けて放出されても、人が冷気あるいは暖気を感じる程度を抑制できる。   In addition, by setting the temperature difference between the air conditioner room and the room to within 5 degrees Celsius during cooling and within 10 degrees Celsius during heating, the air discharged from the duct to each room is released toward the people living in the room. However, the extent to which a person feels cold or warm can be suppressed.

このように本発明によれば、日照時間その他の外部環境の影響を受けても部屋毎の極端な温度差のない住宅環境にすることができる。   As described above, according to the present invention, it is possible to provide a residential environment free from an extreme temperature difference for each room even under the influence of sunshine hours and other external environments.

高気密とは、住宅内に隙間風が入ってこないようにすることであり、高断熱とは住宅の外部と接する部分である外壁、屋根、窓などから、冬なら暖かさを逃さないように、夏なら暑さが入らないようにすることである。よって、具体的に高気密・高断熱住宅とは、気密性を高めるために、微細な隙間も埋められており、断熱性を高めるために、断熱性能が高い断熱材を使用し、窓には複層ガラス入りサッシなどが使用されている住宅をいう。
Example 1
FIG. 1 shows a highly airtight and highly insulated house to which a central air conditioning system S1 according to the present invention is applied.
High airtightness is to prevent drafts from entering the house, and high heat insulation is to avoid the warmth in the winter from outside walls, roofs, windows, etc. that are in contact with the outside of the house. In summer, heat should be kept out. Therefore, specifically, a highly airtight / highly insulated house is filled with minute gaps in order to improve airtightness, and in order to improve heat insulation, heat insulating material with high heat insulating performance is used, and windows are used. This is a house where sashes with double-glazed glass are used.

セントラル空調システムS1は、このような高気密・高断熱住宅の優れた熱的性能を生かすためのものである。
以下、セントラル空調システムS1について述べる。
The central air conditioning system S1 is for taking advantage of the excellent thermal performance of such a highly airtight and highly insulated house.
Hereinafter, the central air conditioning system S1 will be described.

セントラル空調システムS1は、屋根裏に設置された空調機室1内の空調を行う空調機であって冷暖房機能を併せもつ市販の家庭用省エネエアコン(エアー・コンディショナー)2と、一方の口が前記空調機室1を基点になるよう設置され、他方の口が住宅の複数のそれぞれの部屋に導かれるように配管された複数のそれぞれの給気ダクト3と、空調機室1側の前記一方の口に対してそれぞれ設けられた複数の給気(送風)送風機(換気扇)4と、空調機室1に向けて外気OAを送気するための送気ダクト31と、屋外に向けて家屋
の空気を排気するための排気ダクト32とを備える。そして、空調機室1にエアコン2と、各給気ダクト3の一方の口と、給気送風機4と、が配置されている。
The central air conditioning system S1 is an air conditioner that performs air conditioning in the air conditioner room 1 installed in the attic, and is a commercially available home energy-saving air conditioner (air conditioner) 2 that also has a cooling and heating function, and one mouth is the air conditioner. A plurality of air supply ducts 3 installed so that the machine room 1 serves as a base point and the other port is led to a plurality of rooms in the house, and the one port on the air conditioner room 1 side. A plurality of air supply (blower) blowers (ventilation fans) 4 provided to the air conditioner, an air supply duct 31 for supplying outside air OA toward the air conditioner room 1, and air of the house toward the outside And an exhaust duct 32 for exhausting. In the air conditioner room 1, an air conditioner 2, one opening of each air supply duct 3, and an air supply fan 4 are arranged.

以下これらの各構成部材について説明する。
エアコン2は、室内機21が空調機室1に設置され、室外機22が家屋の外に設置されている。エアコン能力は、冷暖房負荷計算により決定する。また、エアコン能力は住宅の構造・施工に大きく依存し、実績に基づく経験値から機器選定を行う必要がある。
なお、断熱区分4地域の通常(140m2程度)の住宅ではエアコンの能力は1台(5
kw相当)で十分である。住宅の形状、住まい方により、2台設置することもある。
Each of these constituent members will be described below.
In the air conditioner 2, the indoor unit 21 is installed in the air conditioner room 1, and the outdoor unit 22 is installed outside the house. The air conditioning capacity is determined by calculating the heating / cooling load. In addition, the air conditioner capacity greatly depends on the structure and construction of the house, and it is necessary to select equipment based on experience based on actual results.
It should be noted that one Air of capacity in the housing of the heat insulation division four regions of the normal (about 2 140m) (5
kw) is sufficient. Two units may be installed depending on the shape of the house and the way of living.

給気ダクト3は、低圧損フレキシブルダクトであることが望ましい。そして、その中を通風するにあたり、空気に抵抗(通風抵抗)ができるだけ掛からないよう、給気ダクト3は、直線的に又は大きな曲率を有する曲線形状で配管されている。   The air supply duct 3 is preferably a low pressure loss flexible duct. The air supply duct 3 is piped linearly or in a curved shape having a large curvature so that resistance (ventilation resistance) is not applied to the air as much as possible when passing through the air.

またこの実施例では、給気ダクト3は、給気SAを、住宅の空調対象の部屋である複数の居室42と床下36にそれぞれ設けられた吹出グリル50から、これら居室42や床下36に向けて吹き出す。なお、給気SAは、エアコン2の吹き出し口から出された冷気や暖気によって温度や湿度が調整された、空調機室1内の空気である。また、居室42等における吹出グリル50の設置場所は、負荷の大きな窓側が好ましい。   Further, in this embodiment, the air supply duct 3 directs the air supply SA from the blow grills 50 provided in the plurality of living rooms 42 and the underfloor 36, which are air-conditioning rooms of the house, to the living room 42 and the underfloor 36, respectively. And blow out. The supply air SA is air in the air conditioner room 1 whose temperature and humidity are adjusted by cold air and warm air emitted from the air outlet of the air conditioner 2. Moreover, the installation location of the blowing grill 50 in the living room 42 or the like is preferably the window side with a large load.

給気送風機4は、空調機室1の壁面に空調対象の居室42の数だけ設置される。当該設置のための設置穴である排気口41が、空調機室1の壁面に複数形成されている。そして、各給気送風機4は、これが排気口41に設置された状態で、給気ダクト3の一方の口とそれぞれ接続されるようになっている。給気送風機4は、直流(DC)モータを駆動源として回転される。   The air supply blowers 4 are installed on the wall surface of the air conditioner room 1 by the number of air-conditioning target rooms 42. A plurality of exhaust ports 41 which are installation holes for the installation are formed on the wall surface of the air conditioner room 1. Each supply blower 4 is connected to one of the intake ducts 3 in a state where the supply blower 4 is installed at the exhaust port 41. The supply air blower 4 is rotated by using a direct current (DC) motor as a drive source.

また、空調機室1は、断熱材で囲繞されている。これにより、エアコン2の吹き出し口から出された冷気や暖気により冷暖房された空調機室1内の空気が、空調機室1の外部に漏れないようになっている。   The air conditioner room 1 is surrounded by a heat insulating material. Thereby, the air in the air conditioner room 1 that has been cooled or heated by the cold air or the warm air emitted from the air outlet of the air conditioner 2 does not leak to the outside of the air conditioner room 1.

さらに、空調機室1には、前記送気ダクト31の一方の口が嵌合されている給気口311と、住宅のホール46と連通路47を介して連通されているガラリ15と、点検やメンテナンスのための専用の点検口17(図2参照)が形成されている。   Further, in the air conditioner room 1, an air supply port 311 into which one port of the air supply duct 31 is fitted, a gallery 15 communicated with a housing hole 46 through a communication passage 47, and inspection. In addition, a dedicated inspection port 17 (see FIG. 2) for maintenance is formed.

送気ダクト31には、その他方の口が家屋の外壁に形成された外気取込口10に取り付けられた、外気導入のための外気導入部である深形フード121、大気中の塵芥を取り除くフィルターユニット13、冷暖房時に発生する熱ロスを抑制するため熱エネルギーを回収する熱交換気ユニット14が設けられている。
ガラリ15は、居室42経由の給気SAでホール46に導入された給気SAを連通路47経由で空調機室1にリターンさせるための通風口である。
In the air supply duct 31, a deep hood 121, which is an outside air introduction portion for introducing outside air, is attached to an outside air intake port 10 formed on the outer wall of the house on the other side, and dust in the atmosphere is removed. A filter unit 13 and a heat exchange air unit 14 that recovers heat energy are provided to suppress heat loss that occurs during cooling and heating.
The gallery 15 is a vent for returning the air supply SA introduced into the hall 46 by the air supply SA via the living room 42 to the air conditioner room 1 via the communication passage 47.

排気ダクト32は、例えば洗濯機・乾燥機・アイロンなどの設備をまとめて設置した部屋であるユーティリティ34や床下36などに設置された排気グリル40を排気の流れの基点にしている。そして、排気グリル40を基点としてそこから排気ダクト32の途中に設けられた熱交換気ユニット14を経由後、家屋の外壁に形成された外気排出のための排出口11に設置された深形フード122から家屋内の空気が屋外に排出される。   The exhaust duct 32 uses, for example, an exhaust grill 40 installed in a utility 34, an underfloor 36, or the like, which is a room in which facilities such as a washing machine, a dryer, and an iron are collectively installed, as a base of exhaust flow. A deep hood installed at the exhaust port 11 for exhausting the outside air formed on the outer wall of the house after passing through the heat exchange air unit 14 provided in the middle of the exhaust duct 32 from the exhaust grill 40 as a starting point. From 122, the air in the house is discharged to the outside.

なお、熱交換気ユニット14、送気ダクト31及び排気ダクト32は、結露防止のため、断熱されている。また、熱交換気ユニット14は、送気ダクト31及び排気ダクト32の通風抵抗を計算し、風量を十分に確保できる仕様のものを選択することが好適である。   In addition, the heat exchange air unit 14, the air supply duct 31, and the exhaust duct 32 are insulated to prevent condensation. In addition, it is preferable that the heat exchange air unit 14 calculates the ventilation resistance of the air supply duct 31 and the exhaust duct 32 and selects a specification that can sufficiently secure the air volume.

さらに、エアコン、排気口、給気口の位置が近すぎて、狭い範囲で空気が循環してしまう現象であるショートサーキットを防止するため、空調機室1にあっては、エアコン2、排気口41、給気口311の設置位置をできるだけ離すことが好ましい。   Furthermore, in order to prevent a short circuit that is a phenomenon in which air is circulated in a narrow range because the positions of the air conditioner, the exhaust port, and the air supply port are too close, the air conditioner room 1 has an air conditioner 2 and an exhaust port. 41. It is preferable to separate the installation positions of the air supply port 311 as much as possible.

そして、本システムS1にあっては、空調機室1内の目標温度と、居室42の目標温度との温度差が冷房時最大摂氏5度以内、暖房時最大摂氏10度以内になるように小さく設定され、給気送風機4による空気排出量が最低100m3/hになるように大きく設定されている。   In the present system S1, the temperature difference between the target temperature in the air conditioner room 1 and the target temperature in the living room 42 is small so that it is within 5 degrees Celsius during cooling and within 10 degrees Celsius during heating. The air discharge amount by the supply air blower 4 is set so as to be at least 100 m 3 / h.

夏の冷房の場合でいえば、空調機室の温度が摂氏23度となる能力の空調機を選定し設定する。また、冬の暖房の場合でいえば、空調機室の温度が摂氏18度となる能力の空調機を選定し設定する。さらに、熱損失係数であるQ値及び相当隙間面積であるC値は、それぞれ2.4w/m2℃及び1.0cm2/m2程度あれば、十分に冷暖房が可能である。
但し、空調機室の温度は摂氏23度や18度に限定されるわけではない。また温度差は冷房時摂氏5度、暖房時摂氏10度よりも小さくてもよい。
In the case of summer cooling, an air conditioner having the ability to set the temperature of the air conditioner room to 23 degrees Celsius is selected and set. Further, in the case of winter heating, an air conditioner having the ability to set the temperature of the air conditioner room to 18 degrees Celsius is selected and set. Furthermore, if the Q value as the heat loss coefficient and the C value as the equivalent gap area are about 2.4 w / m 2 ° C. and 1.0 cm 2 / m 2, respectively, sufficient cooling and heating are possible.
However, the temperature of the air conditioner room is not limited to 23 degrees Celsius or 18 degrees Celsius. The temperature difference may be smaller than 5 degrees Celsius during cooling and 10 degrees Celsius during heating.

このような設定にできるのは、高気密高断熱住宅では、所定限度の風量が確保できれば、熱負荷を処理するための冷温風に大温度差が必要ないからである。なお熱負荷とは、暖房時に熱が屋外に逃げ、冷房時には熱が屋外から流入するような、熱損失と熱取得の量のことを言う。   The reason why such a setting can be made is that, in a highly airtight and highly insulated house, if a predetermined amount of airflow can be secured, there is no need for a large temperature difference in the cool and warm air for treating the heat load. The heat load refers to the amount of heat loss and heat acquisition such that heat escapes to the outdoors during heating and heat flows from the outdoors during cooling.

次にこのような構成のセントラル空調システムS1を使用した場合の空気の循環について述べる。
給気送風機4を直流モータで駆動すると、空調機室1を起点とした空気の循環を生じる。
Next, air circulation when the central air conditioning system S1 having such a configuration is used will be described.
When the air supply blower 4 is driven by a DC motor, air circulation starts from the air conditioner room 1.

最初に空調機室1内の空気が給気ダクト3経由で各居室42及び床下36に向けて送気される。当該送気された空気に相当する量の外気OAが、外気取込口10に取り付けられた深形フード121から送気ダクト31に入る。   First, the air in the air conditioner room 1 is sent to the living rooms 42 and the underfloor 36 via the air supply duct 3. An amount of outside air OA corresponding to the supplied air enters the air supply duct 31 from the deep hood 121 attached to the outside air intake 10.

当該外気OAは、フィルターユニット13により外気OAに含まれている塵芥が取り除かれる。その後、熱交換気ユニット14を経由して、空調機室1の給気口311から外気OAは空調機室1に導入される。空調機室1に導入された外気OAは、エアコン2の設定温度にされてから、給気ダクト3経由で各居室42及び床下36に向けて送気される。   The dust contained in the outside air OA is removed from the outside air OA by the filter unit 13. Thereafter, outside air OA is introduced into the air conditioner room 1 from the air supply port 311 of the air conditioner room 1 via the heat exchange air unit 14. After the outside air OA introduced into the air conditioner room 1 is set to the set temperature of the air conditioner 2, the outside air OA is sent to each living room 42 and the underfloor 36 via the air supply duct 3.

居室42に送られた給気SAは、その後、居室42の通気口43からホール46を経由した後、ユーティリティ34にその通気口35を介して至る。その後、給気SAは、室内空気RAとして、ユーティリティ34に設置された排気グリル40を基点としてそこから排気ダクト32を通り、熱交換気ユニット14を経由して、排気EAとして屋外に排出される。   The supply air SA sent to the living room 42 then passes through the hole 46 from the vent 43 of the living room 42 and then reaches the utility 34 via the vent 35. Thereafter, the supply air SA is exhausted to the outside as exhaust air EA through the exhaust air duct 32 from the exhaust grill 40 installed in the utility 34 as the indoor air RA, through the exhaust duct 32 therefrom. .

また、吹出グリル50から床下36に送気された給気SAは、その後、床下36に設置された排気グリル40からダクト32を通り、熱交換気ユニット14を経由して、同じく排気EAとして屋外に排出される。   In addition, the supply air SA sent from the blowout grill 50 to the underfloor 36 then passes through the duct 32 from the exhaust grille 40 installed in the underfloor 36, passes through the heat exchange air unit 14, and is also outdoors as exhaust EA. To be discharged.

さらに、居室42等の室内空気RAは、ユーティリティ34に流れる以外に、ホール46の連通路47を経由して空調機室1へ送られる。   Furthermore, the room air RA such as the living room 42 is sent to the air conditioner room 1 via the communication path 47 of the hall 46 in addition to flowing to the utility 34.

次に作用効果について述べる。
本システムS1にあっては、空調機室1内の温度と、居室42等の目標温度との温度差が最大5度以内になるように小さく設定され、給気送風機4による空気排出量が最低100m3/hになるように設定されている。
Next, operational effects will be described.
In the present system S1, the temperature difference between the temperature in the air conditioner room 1 and the target temperature of the living room 42 and the like is set to be within 5 degrees at the maximum, and the amount of air discharged by the air supply blower 4 is the lowest. It is set to be 100 m3 / h.

したがって、居室42等の目標温度と、通気口43から居室42に導入される空気の温度との差は、冷房時摂氏5度、暖房時摂氏10度よりさらに小さい。したがって、居室42等に居住する人に通気口43から導入された空気があたっても温度差による不快感を持つことが少ない。   Therefore, the difference between the target temperature of the living room 42 and the like and the temperature of the air introduced into the living room 42 from the vent 43 is even smaller than 5 degrees Celsius during cooling and 10 degrees Celsius during heating. Therefore, even if a person living in the living room 42 or the like is exposed to the air introduced from the vent hole 43, there is little discomfort due to the temperature difference.

さらに、本システムS1にあっては、ヒートショックを生じ難い。ヒートショックとは、急激な温度の変化が、身体に及ぼす影響のことをいう。例えば、冬の入浴時の脱衣室から浴室への急激な温度変化は、血管を著しく伸縮させるとともに、血圧や脈拍を大きく変動させる。これにより、脳梗塞や、脳出血を引き起こすことがある。   Furthermore, in this system S1, heat shock is unlikely to occur. Heat shock refers to the effect of sudden temperature changes on the body. For example, a rapid temperature change from the dressing room to the bathroom during bathing in winter causes the blood vessels to remarkably expand and contract, and the blood pressure and pulse to fluctuate greatly. This may cause cerebral infarction or cerebral hemorrhage.

さらにまた、量販の省エネルギーのエアコン2や、同じく量販される直流モータにより駆動する、給気送風機4を利用するので、安価である。安価であるからリニューアルするのも比較的容易である。   Furthermore, it is inexpensive because it uses the energy-saving air conditioner 2 for mass sales and the air supply blower 4 that is driven by a DC motor that is also mass-sold. Renewal is relatively easy because it is inexpensive.

加えて、給気送風機4を回転するのに直流モータを利用することで、交流(AC)モータに比べ、消費電流を数分の1にできる(最大30〜75%の消費電力の低減が可能)。このように、市販品を使用することにより、市販品の省エネルギー性能を家屋全体の空調に生かすことができる。   In addition, by using a direct current motor to rotate the air supply blower 4, the current consumption can be reduced to a fraction of that of an alternating current (AC) motor (maximum power consumption can be reduced by 30 to 75%). ). Thus, by using a commercial item, the energy-saving performance of a commercial item can be utilized for the air conditioning of the whole house.

そして、エアコン2、直流モータにより駆動する給気送風機4は量販品であるので、本システムの構築にあたり、コスト負担や生産対応力は何ら問題ない。   The air conditioner 2 and the air supply fan 4 driven by the direct current motor are mass-produced products, so there is no problem with the cost burden and the production response capability when constructing this system.

さらに、給気ダクト3は、低圧損フレキシブルダクトが採用されているので、通風抵抗が掛かりにくい。したがって、給気ダクト3内の圧力損失の低減が可能である。そして、給気ダクト3の配置は、直線的又は大きな曲率を有する曲線形状で配管されているため、その内部を清掃し易い。   Furthermore, since the air supply duct 3 employs a low-pressure loss flexible duct, it is difficult for the ventilation resistance to be applied. Therefore, the pressure loss in the air supply duct 3 can be reduced. And since arrangement | positioning of the air supply duct 3 is piping by the curve shape which has a linear or big curvature, it is easy to clean the inside.

さらにまた、屋根裏に設置された空調機室1にエアコン2や給気送風機4等の機器を集約してあるので、メンテナンスの最中にメンテナンス作業者と居住者とが接することがなく、両者が互いに気遣いをする必要がない。   Furthermore, since the air conditioner room 1 and the air supply fan 4 are gathered in the air conditioner room 1 installed in the attic, the maintenance worker and the resident are not in contact with each other during the maintenance. There is no need to care for each other.

そして、ダクト内を大風量が流れるため、ダクト内におけるカビの発生を抑制することができる。
また、屋根裏にも給気送風機による冷気を送れるように本システムを適用すれば夏場は屋根裏に溜まった熱気を除去することができる(図2参照)。
And since a large airflow flows in a duct, generation | occurrence | production of mold | fungi in a duct can be suppressed.
Moreover, if this system is applied so that the cool air from the air supply blower can be sent to the attic, the hot air accumulated in the attic can be removed in summer (see FIG. 2).

本願発明はあくまで、セントラル空調システムの空調機としては、エアコン能力の小さな市販の家庭用省エネエアコン(エアー・コンディショナー)を空調機室に設置してある。
しかしながら、一方の口が前記空調機室1を基点になるよう設置され、他方の口が住宅の複数のそれぞれの部屋に導かれるように配管された複数のそれぞれの給気ダクト3と、空調機室1側の前記一方の口に対してそれぞれ設けられた複数の給気(送風)送風機(換気扇)4とで大きな風量を住宅の複数のそれぞれの部屋に供給するものである。このため、エアコンの吹き出し口から出る風量の温度が、夏場であればさほど低くなくとも、給気送風機4によって各部屋に供給される風量が多い分、涼しく感じることができる。
In the present invention, as an air conditioner of the central air conditioning system, a commercially available home energy-saving air conditioner (air conditioner) having a small air conditioner capacity is installed in the air conditioner room.
However, a plurality of air supply ducts 3 installed such that one of the ports is set to be the base point of the air conditioner room 1 and the other port is led to each of a plurality of rooms of the house, and the air conditioner A large amount of air is supplied to each of a plurality of rooms of the house by a plurality of air supply (blower) blowers (ventilation fans) 4 provided for the one opening on the side of the room 1. For this reason, even if the temperature of the air volume coming out from the air outlet of the air conditioner is not so low in summer, it can be felt cool because the air volume supplied to each room by the air supply blower 4 is large.

また、冬場であれば、エアコンの吹き出し口から出る風量の温度が、さほど高くなくとも、給気送風機4によって各部屋に供給される風量が多い分暖かく感じることができる。
具体的には既述のように、空調機室1内の目標温度と、居室42の目標温度との温度差が冷房時最大摂氏5度以内、暖房時最大摂氏10度以内になるように小さく設定し、給気送風機4による空気排出量が最低100m3/hになるように大きく設定することで、望まれない局部気流(ドラフト)を生じないようにできるのである。
Further, in the winter season, even if the temperature of the air volume coming out from the air outlet of the air conditioner is not so high, it can be felt warm because the air volume supplied to each room by the air supply blower 4 is large.
Specifically, as described above, the temperature difference between the target temperature in the air conditioner room 1 and the target temperature in the living room 42 is small so that it is within 5 degrees Celsius during cooling and within 10 degrees Celsius during heating. By setting and setting it large so that the amount of air discharged by the air supply blower 4 is at least 100 m 3 / h, it is possible to prevent unwanted local airflow (draft) from occurring.
