Description

本発明は、建物内の24時間換気を実施しながら、建物内の冷暖房を行い、空気を清浄化する機能を有する空調技術に関する。   The present invention relates to an air conditioning technique having a function of performing air conditioning in a building and purifying air while performing ventilation for 24 hours in the building.
建築物の内部の冷暖房を行う空調システムとしては、所謂、ルームエアコンなどの空調装置を用いたものが代表的である。従来の空調装置は、室外機で適度に温度調節された空気流を室内機から建物内に吹き出すことにより空調を行うものであるが、特に夏の暑い時季は、室内機から吹き出す空調空気によって生じる気流感により涼しく感じることができるが、場合によってはドラフトという不快な現象が発生することがある。   A typical air conditioning system that cools and heats the interior of a building is one that uses an air conditioner such as a so-called room air conditioner. Conventional air conditioners perform air conditioning by blowing an air flow that has been appropriately temperature-controlled by an outdoor unit from the indoor unit into the building, but this is caused by conditioned air that is blown from the indoor unit, particularly in the hot summer season. Although it can feel cool due to the feeling of airflow, an unpleasant phenomenon called draft may occur in some cases.
そこで、室内に配置された放熱器に熱媒を循環供給し、放熱器から輻射される熱気や冷気により室内の空調を行う方式が提案されている(例えば、特許文献1参照。)。特許文献1記載の「冷暖房システム」は、冷暖房パネルと、この冷暖房パネルの内部に高温あるいは低温の流体を流通させる流体供給装置とを備え、流体供給装置として、配管と、ポンプと、燃料ボイラと、ヒートポンプとが設けられている。   In view of this, a method has been proposed in which a heat medium is circulated and supplied to a radiator disposed in a room, and indoor air conditioning is performed using hot air or cold air radiated from the radiator (see, for example, Patent Document 1). The “air-conditioning system” described in Patent Document 1 includes an air-conditioning panel and a fluid supply device for circulating a high-temperature or low-temperature fluid inside the air-conditioning panel. As the fluid supply device, a pipe, a pump, a fuel boiler, A heat pump is provided.
一方、本発明に関連する従来技術として、例えば、特許文献2記載の「住宅換気構造」がある。特許文献2記載の「住宅換気構造」は、冷暖房機能は備えていないが、屋外から吸入した空気を住宅内へ導き入れる空気供給装置と、空気供給装置に一端が連通された給気用ダクトと、この給気用ダクトの他端に連通された給気ガラリ(給気口)と、を備え、空気ガラリ(給気口)を、部屋内の壁面下部や床面端部に形成したものである。   On the other hand, as a conventional technique related to the present invention, for example, there is a “house ventilation structure” described in Patent Document 2. The “house ventilation structure” described in Patent Document 2 does not have a cooling / heating function, but includes an air supply device that introduces air sucked from outside into the house, and an air supply duct that is connected at one end to the air supply device. The air supply louver (air supply port) communicated with the other end of the air supply duct, and the air louver (air supply port) is formed at the lower part of the wall surface or the end of the floor surface in the room. is there.

従来の空調装置(ルームエアコンなど)の室内機は運転中にファンの回転音や空気吹き出し音を発するので、静寂性に欠ける面がある。また、特許文献1に記載された放熱器のみによる空調システムは、無風状態でありながら、輻射作用により快適な空調空間を実現することができるが、24時間換気機能及び建物内へ清浄化された外気を導入する機能を具備していないので、空調作用や換気作用が不十分である。   A conventional air conditioner (room air conditioner, etc.) indoor unit emits a rotating sound of a fan or an air blowing sound during operation, and thus lacks quietness. Moreover, although the air conditioning system only by the heat radiator described in patent document 1 can implement | achieve a comfortable air-conditioned space by a radiation effect, even if it is a no-wind state, it was cleaned into the 24-hour ventilation function and the building Since it does not have a function to introduce outside air, air conditioning and ventilation are insufficient.
一方、特許文献2記載の「住宅換気構造」は、気流による居住者などへの不快感を低減させることができ、換気効率の低減を防止することもできるが、部屋内の低い部分に設けられている給気ガラリ(給気口)を家具や調度品で塞がないようにする必要があるため、部屋内における家具や調度品などの配置が著しく制約される。   On the other hand, the “house ventilation structure” described in Patent Document 2 can reduce discomfort to residents and the like due to airflow, and can prevent a reduction in ventilation efficiency, but is provided in a low part of the room. Since it is necessary to prevent the air supply louver (air supply opening) from being blocked by furniture or furniture, the arrangement of furniture and furniture in the room is significantly restricted.
本発明が解決しようとする課題は、24時間換気と輻射空調を行いながら、屋外の汚染物質などの建物内への侵入を防止し、建物内を常に静寂かつ快適で清浄な雰囲気に保つことができ、家具や調度品などの配置状態が制約されることがなく、より確実な空調作用、換気作用を得ることができる空調システムを提供することにある。   The problem to be solved by the present invention is to prevent the entry of outdoor pollutants into the building while keeping ventilation and radiant air conditioning for 24 hours, and to keep the building in a quiet, comfortable and clean atmosphere at all times. It is possible to provide an air conditioning system that can obtain a more reliable air conditioning action and ventilation action without restricting the arrangement state of furniture and furniture.

The air conditioning system of the present invention is
A radiator disposed in the building to circulate the temperature-controlled heat medium inside and discharge the warm air or cold air from the surface to perform air conditioning,
A heat source device arranged outside the building to adjust the temperature of the heat medium;
A first flow path for circulating the heat medium between the radiator and the heat source unit;

In an air conditioning system comprising a second flow path for circulating the heat medium between the heat exchanger and the heat source machine,
The air supply port of the air supply path is at least a floor surface below the operation area of the opening / closing means disposed in the building, a floor surface facing the operation area of the opening / closing means, or a floor of a resident movement area in the building It is provided on the surface.
ここで、前記開閉手段とは、部屋の出入り口や物品収納空間の出し入れ口などを開閉する手段をいい、蝶番を中心に回動するドアや扉、敷居やレールに沿ってスライドする引き戸などを含む。また、開閉手段の動作領域に臨む床面とは、前記動作領域に近接した場所に位置する床面をいう。   Here, the opening / closing means refers to means for opening / closing a doorway of a room or an entrance / exit of an article storage space, and includes a door or a door that rotates around a hinge, a sliding door that slides along a sill or rail, and the like. . Further, the floor surface facing the operation area of the opening / closing means refers to a floor surface located at a location close to the operation area.
一般的な建物の内部において、当該建物内に配備された開閉手段の動作領域下方の床面、前記開閉手段の動作領域に臨む床面若しくは前記建物内の居住者移動領域の床面は、本来、家具などを設置できない場所であるため、このような場所に給気口を設ければ、給気口の設置場所の選定に迷う必要がなくなり、家具や調度品などの配置状態が制約されることもない。また、このような場所に給気口を設ければ、壁面の上方に設けられることの多い、排気経路の排気口に向かって空気が流動するときに、建物内を淀みなく空気流が通過するので、より確実な空調作用、換気作用を得ることができる。   In a general building, the floor under the operating area of the opening / closing means deployed in the building, the floor facing the operating area of the opening / closing means, or the floor of the occupant movement area in the building is originally Because it is a place where furniture etc. cannot be installed, if an air supply port is provided in such a place, there is no need to hesitate in selecting the installation place of the air supply port, and the arrangement state of furniture and furniture is restricted There is nothing. If an air supply port is provided in such a place, an air flow passes through the building without stagnation when air flows toward the exhaust port of the exhaust path, which is often provided above the wall surface. Therefore, more reliable air conditioning and ventilation can be obtained.
ここで、前記建物を形成する壁部、床部及び天井部の内部にダクトレス空間を気密状に形成し、前記ダクトレス空間を前記給気経路の少なくとも一部をなす通気経路とすることができる。   Here, a ductless space can be formed in an airtight manner inside the wall, floor, and ceiling that form the building, and the ductless space can be used as a ventilation path that forms at least part of the air supply path.
このような構成とすれば、給気経路を経由して建物内に導入された外気を、前記ダクトレス空間を通気経路として利用して各部屋に供給することが可能となるので、建物内に外気導入用のダクトを施工する必要がなくなり、資材の削減及び施工の容易化を図ることができる。   With such a configuration, the outside air introduced into the building via the air supply path can be supplied to each room using the ductless space as a ventilation path. It is no longer necessary to construct a duct for introduction, and materials can be reduced and construction can be facilitated.
また、前記建物の1階天井部と2階床部との間にダクトレス空間を気密状に形成し、前記ダクトレス空間を前記通気経路とすることができる。   Further, a ductless space can be formed in an airtight manner between the first floor ceiling and the second floor of the building, and the ductless space can be used as the ventilation path.
このような構成とすれば、建物の1階天井部と2階床部との間に形成されたダクトレス空間を通気経路として利用して、給気経路を経由して建物内へ導入された外気を建物内へ供給することが可能となる。従って、前記通気経路の下方や上方に位置する部屋内に給気口を設置することにより、前記給気手段から前記給気経路及び前記通気経路を経由して前記給気口に至る流路が形成され、ダクトの施工が不要となる。   With such a configuration, the outside air introduced into the building via the air supply path using the ductless space formed between the first floor ceiling and the second floor of the building as a ventilation path. Can be supplied into the building. Therefore, by installing an air supply port in a room located below or above the ventilation path, a flow path from the air supply means to the air supply port via the supply path and the ventilation path is provided. It is formed and duct construction becomes unnecessary.
また、前記通気経路として利用する前記ダクトレス空間には、熱交換器で温度調節された外気が流通するので、前記ダクトレス空間に接する天井面や床面を介して、部屋内に対する輻射作用が生じ、空調効果が向上する。   In addition, since the outside air whose temperature is adjusted by a heat exchanger flows through the ductless space used as the ventilation path, a radiation action occurs in the room through the ceiling surface and the floor surface in contact with the ductless space. The air conditioning effect is improved.
また、前記通気経路と連通する給気口を、前記建物内の1階天井部に設けることもできる。   In addition, an air supply port communicating with the ventilation path can be provided in the first floor ceiling portion in the building.
このような構成とすれば、1階天井部は前記通気経路(ダクトレス空間)に接しているため、この場所に給気口を設ければ、給気口と前記通気経路とが連通するため、施工の簡略化を図ることができる。なお、前記給気口は、1階天井部に設けられた開口部に通気部材を設置することによって形成することができる。   With such a configuration, the first floor ceiling part is in contact with the ventilation path (ductless space), so if an air supply port is provided in this place, the air supply port and the ventilation path communicate with each other. The construction can be simplified. In addition, the said air supply opening can be formed by installing a ventilation member in the opening part provided in the 1st floor ceiling part.
さらに、前記壁部、前記床部及び前記天井部に発泡断熱構造を設けることにより前記ダクトレス空間を形成することができる。   Furthermore, the ductless space can be formed by providing a foam heat insulating structure on the wall portion, the floor portion, and the ceiling portion.
このような構成とすれば、前記ダクトレス空間に断熱性と気密性の両方を持たせることができるので、温度調節された状態で前記ダクトレス空間に導入される外気の温度ロス(冷気や暖気の散逸)を抑制することができ、空調効果の向上に有効である。   With such a configuration, the ductless space can be provided with both heat insulation and airtightness, so that temperature loss of the outside air introduced into the ductless space in a temperature-controlled state (dissipation of cold air and warm air) ), And is effective in improving the air conditioning effect.
本発明により、24時間換気と輻射空調を行いながら、屋外の汚染物質などの建物内への侵入を防止し、建物内を常に静寂かつ快適で清浄な雰囲気に保つことができ、家具や調度品などの配置状態が制約されることがなく、より確実な空調作用、換気作用を得ることができる空調システムを提供することができる。   According to the present invention, while performing 24-hour ventilation and radiant air-conditioning, it is possible to prevent the entry of outdoor pollutants into the building and keep the building in a quiet, comfortable and clean atmosphere. Thus, it is possible to provide an air-conditioning system that can obtain more reliable air-conditioning action and ventilation action without restricting the arrangement state.

The part corresponds to the floor of the resident movement area.
図1に示す空調システム100において熱源機12及び給気手段15を稼働させると、熱源機12において温度調節された熱媒が、第1流通経路13を経由して各部屋1,2,3,4内の放熱器11との間で循環するとともに、第2流通経路18を経由して熱交換器17との間で循環する。これと並行して、給気手段15により、建物10の外部から、清浄化手段16を通過して吸い込まれた外気が熱交換器17、給気経路14及び開口部10bなどを経由して給気口21から部屋1,2,3,4内へ流入する。このとき、給気手段15の送風能力及び排気経路5,6,7,8の開度は、建物10内の気圧が正圧を維持することができるように設定され、熱源機12及び給気手段15はいずれも連続稼働(所謂、24時間運転)することができる。従って、空調システム100は、第2種換気方式の24時間換気機能を発揮する。   When the heat source unit 12 and the air supply unit 15 are operated in the air conditioning system 100 shown in FIG. 1, the heat medium whose temperature is adjusted in the heat source unit 12 passes through the first distribution path 13 to each of the rooms 1, 2, 3, 3. 4 circulates between the heat sink 11 and the heat exchanger 17 via the second flow path 18. In parallel with this, the outside air sucked from the outside of the building 10 through the cleaning means 16 is supplied by the air supply means 15 via the heat exchanger 17, the air supply path 14, the opening 10b, and the like. It flows into the rooms 1, 2, 3, and 4 from the mouth 21. At this time, the blowing capacity of the air supply means 15 and the opening degree of the exhaust paths 5, 6, 7, and 8 are set so that the atmospheric pressure in the building 10 can maintain a positive pressure, and the heat source machine 12 and the air supply Any of the means 15 can be operated continuously (so-called 24-hour operation). Therefore, the air conditioning system 100 exhibits a 24-hour ventilation function of the second type ventilation system.
空調システム100において、季節(気温)に応じて熱源機12で温度調節された熱媒を、第一流通経路13を経由して、建物10内の各部屋1,2,3,4に配置された放熱器11に循環させることにより、各放熱器11から放出される暖気若しくは冷気により、それぞれの部屋1,2,3,4内を適切な温度で暖房したり、冷房したりする輻射空調を行うことができる。また、空調システム100においては、建物10内に電動式の送風ファンなどを設ける必要がないので、当該空調システム100が稼働しているときも建物10内を静寂に保つことができる。   In the air conditioning system 100, the heat medium whose temperature is adjusted by the heat source device 12 according to the season (air temperature) is arranged in each room 1, 2, 3, 4 in the building 10 via the first distribution path 13. By circulating through the radiator 11, radiant air conditioning that heats or cools the interiors of the respective rooms 1, 2, 3, 4 at an appropriate temperature by warm air or cold air discharged from each radiator 11 is performed. It can be carried out. Further, in the air conditioning system 100, since it is not necessary to provide an electric blower fan or the like in the building 10, the inside of the building 10 can be kept quiet even when the air conditioning system 100 is operating.
また、給気手段15により導入される外気は、清浄化手段16で浄化され、熱交換器17で適切な温度に調節され、建物10内の気圧を正圧に保持できるような風圧(風量)で建物10内に供給される。即ち、給気手段15により建物10内へ導入される外気は図1中の矢線で示すように、給気経路14を経由して部屋1,2,3,4内へ流入して拡散した後、それぞれの一部は排気経路5,6,7,8から屋外へ排出される。   The outside air introduced by the air supply means 15 is purified by the cleaning means 16, adjusted to an appropriate temperature by the heat exchanger 17, and the wind pressure (air volume) that can maintain the atmospheric pressure in the building 10 at a positive pressure. Is supplied into the building 10. That is, the outside air introduced into the building 10 by the air supply means 15 flows into the rooms 1, 2, 3 and 4 via the air supply path 14 and diffuses as indicated by the arrow in FIG. Thereafter, a part of each is discharged to the outdoors from the exhaust passages 5, 6, 7, and 8.
従って、屋外の汚染物質などが外気に伴って建物10内へ侵入するのを防止しながら、建物10内を常に快適で清浄な雰囲気に保つことができる第2種換気方式の24時間換気を実行することができる。また、暖房及び冷房が不要な中間期においては、熱源機12の運転を停止して、放熱器11及び熱交換器17の機能を停止する一方、給気手段15を連続運転することにより、第2種換気方式の24時間換気を行うことができる。また、清浄化手段16としては、空気中の塵埃などを捕捉する機能を有するフィルタが好適であるが、エアワッシャなどを使用することもできる。   Therefore, the 24-hour ventilation of the second type ventilation system that can keep the inside of the building 10 in a comfortable and clean atmosphere while preventing outdoor pollutants from entering the building 10 with the outside air. can do. Further, in the intermediate period when heating and cooling are not required, the operation of the heat source unit 12 is stopped and the functions of the radiator 11 and the heat exchanger 17 are stopped, while the air supply means 15 is continuously operated, thereby Two-hour ventilation can be performed for 24 hours. As the cleaning means 16, a filter having a function of capturing dust in the air is suitable, but an air washer or the like can also be used.
なお、空調システム100においては、第2種換気方式を採用しているが、これに限定するものではないので、例えば、第1種換気方式を採用することもできる。第1種換気方式は、給気及び排気の両方を電動ファンなどの機械的送気手段を用いて行う換気方式であるため、給気量>排気量となるように給排気量を設定すれば、前述した第2種換気方式と同様の効果を得ることができる。   In addition, although the 2nd type ventilation system is employ | adopted in the air conditioning system 100, it is not limited to this, For example, a 1st type ventilation system can also be employ | adopted. The first type ventilation method is a ventilation method in which both air supply and exhaust are performed using mechanical air supply means such as an electric fan. Therefore, if the air supply / exhaust amount is set so that the air supply amount> the exhaust amount, The same effects as those of the second type ventilation method described above can be obtained.
一方、図2に示すように、建物10の内部において、部屋1の出入り口1aの開閉手段であるドア1bの動作領域1dの下方に位置する床面1fは、本来、居住者移動領域の床面に相当し、家具などを設置できない場所であるため、このような場所に給気口21を設ければ、給気口の設置場所の選定に迷う必要がなくなり、家具や調度品などの配置状態が制約されることもない。給気口21は、床面1fに開設された開口部21xに通気部材21y(例えば、グリルなど)を設置することによって形成することができるが、これに限定されない。   On the other hand, as shown in FIG. 2, the floor surface 1f located below the operation area 1d of the door 1b, which is an opening / closing means for the entrance / exit 1a of the room 1, is originally a floor surface of the occupant movement area. Since it is a place where furniture or the like cannot be installed, if the air supply port 21 is provided in such a place, there is no need to hesitate to select the installation location of the air supply port, and the arrangement state of furniture and furniture etc. Is not constrained. The air supply port 21 can be formed by installing a ventilation member 21y (for example, a grill or the like) in the opening 21x opened in the floor surface 1f, but is not limited thereto.
なお、給気口21を設けた領域は人間やペットなどが通行する場所であるため、給気口21上に荷重が加わったときに破損しない程度の強度を有する構造とするとともに、給気口21で躓いたり、給気口21に足が引っ掛かったりするのを防止するため、給気口21と周囲の床面1fとが略同一平面をなす構造(給気口21と周囲の床面1fとの間に段差が生じない構造)とすることが望ましい。   Since the region where the air supply port 21 is provided is a place where people, pets, and the like pass, the structure is strong enough to prevent damage when a load is applied to the air supply port 21, and the air supply port In order to prevent crawling at 21 or catching a foot on the air supply port 21, the air supply port 21 and the surrounding floor surface 1 f are substantially flush with each other (the air supply port 21 and the surrounding floor surface 1 f It is desirable to have a structure in which no step is generated between
また、図2に示すような場所に給気口21を設ければ、壁面の上方に設けられることの多い、排気経路5の排気口に向かって空気が流動するときに、部屋1内を淀みなく空気流が通過するので、より確実な空調作用、換気作用を得ることができる。さらに、給気口21に指向性を持たせれば、給気口21から吹き出した気流が部屋を一巡するようにすることができるので空調作用、換気作用の向上に有効である。   Further, if the air supply port 21 is provided in a place as shown in FIG. 2, the air is swallowed in the room 1 when air flows toward the exhaust port of the exhaust path 5, which is often provided above the wall surface. Since the air flow passes therethrough, more reliable air conditioning and ventilation can be obtained. Furthermore, if the air supply port 21 has directivity, the air flow blown out from the air supply port 21 can make a round of the room, which is effective in improving the air conditioning function and the ventilation function.
また、建物10の1階天井部C1と2階床部F2との間に形成されたダクトレス空間を、給気経路14の一部をなす気密断熱性の通気経路19としたことにより、給気口21から部屋3,4内へ導入される外気流を確保することができるので、確実な換気作用を得ることができる。また、通気経路19が給気経路として機能するので、給気口21に接続するダクトの施工が不要となり、資材の削減及び施工の容易化を図ることができる。また、通気経路19に面する1階天井部C1や2階床部F2を介して輻射作用が生じるので、空調効果の向上に有効である。   Further, the ductless space formed between the first-floor ceiling portion C1 and the second-floor floor portion F2 of the building 10 is used as an air-tight heat-insulating air passage 19 that forms a part of the air-supply passage 14. Since the external airflow introduced into the rooms 3 and 4 from the mouth 21 can be ensured, a reliable ventilation effect can be obtained. Moreover, since the ventilation path 19 functions as an air supply path, it is not necessary to install a duct connected to the air supply port 21, and it is possible to reduce materials and facilitate the installation. Further, since the radiation action is generated through the first floor ceiling C1 and the second floor F2 facing the ventilation path 19, it is effective in improving the air conditioning effect.
図1に示す空調システム100において、第1流通経路13、第2流通経路18の少なくとも一方に経路開閉手段(図示せず)を設ければ、空調負荷などに応じて、前記経路開閉手段を開閉することにより、第1流通経路13に接続された放熱器11、第2流通経路18に接続された熱交換器17のいずれか一方のみの運転が可能となるので、空調効率の向上に有効である。   In the air conditioning system 100 shown in FIG. 1, if a path opening / closing means (not shown) is provided in at least one of the first distribution path 13 and the second distribution path 18, the path opening / closing means is opened / closed according to an air conditioning load or the like. This makes it possible to operate only one of the radiator 11 connected to the first flow path 13 and the heat exchanger 17 connected to the second flow path 18, which is effective in improving the air conditioning efficiency. is there.
例えば、放熱器11による輻射空調を行いながら、外気をそのまま取り入れたい場合(輻射空調のみを行いたい場合など)は、熱交換器17に接続される第2流通経路18の途中に設けた前記経路開閉手段(図示せず)を閉止して、熱交換器17への熱媒の循環を停止させることによって実現することができる。また、第1流通経路13に設けた経路開閉手段(図示せず)を閉止して、放熱器11への熱媒の循環を停止させれば、外気の温度調節のみの運転も可能である。   For example, when it is desired to take outside air as it is while performing radiation air conditioning with the radiator 11 (for example, when only radiation air conditioning is desired), the path provided in the middle of the second distribution path 18 connected to the heat exchanger 17. This can be realized by closing the opening / closing means (not shown) and stopping the circulation of the heat medium to the heat exchanger 17. Moreover, if the path opening / closing means (not shown) provided in the first circulation path 13 is closed and the circulation of the heat medium to the radiator 11 is stopped, the operation only for adjusting the temperature of the outside air is possible.
また、熱交換器17の熱源として、放熱器11の熱源である熱源機12を利用することにより、建物10内へ導入する外気の温度調節用の熱源を別途、設ける必要がなくなるので、構造の簡素化、設置スペースの削減を図ることができる。   Further, by using the heat source unit 12 that is the heat source of the radiator 11 as the heat source of the heat exchanger 17, it is not necessary to separately provide a heat source for adjusting the temperature of the outside air introduced into the building 10. Simplification and reduction of installation space can be achieved.
さらに、外気を熱交換器17で熱交換して建物10内へ導入するので、特に夏場は高温多湿の外気を冷却することで除湿、冷却された外気を導入することができ、建物10内を快適な状態にすることができる。なお、夏場は特に放熱器11表面に結露が発生することがあるが、建物10内へ導入する外気を予め除湿冷却すれば、放熱器11表面に発生する結露を緩和させることができる。   Furthermore, since the outside air is heat-exchanged by the heat exchanger 17 and introduced into the building 10, particularly in summer, the outside air that has been dehumidified and cooled can be introduced by cooling the high-temperature and high-humidity outside air. It can be in a comfortable state. Note that condensation may occur on the surface of the radiator 11 particularly in summer. However, if the outside air introduced into the building 10 is dehumidified and cooled in advance, the condensation generated on the surface of the radiator 11 can be reduced.
一方、排気経路5,6,7,8にそれぞれ逆流防止機能を有する差圧調節手段9が設けられているため、建物10内の気圧と建物外の気圧との間に所定の圧力差を設定することができ、建物10内を常に安定した正圧に保つことができる。この場合、建物10内の気圧と建物外の気圧との圧力差は5Pa〜10Pa程度に設定することが望ましい。また、建物10に設けられた扉(図示せず)などの開閉操作により建物10内の気圧が変動した場合、これに追随して、差圧調節手段9の逆流防止機能が作動するので、排気経路5,6,7,8からの外気侵入を防止することができる。   On the other hand, since the differential pressure adjusting means 9 having a backflow prevention function is provided in each of the exhaust paths 5, 6, 7, and 8, a predetermined pressure difference is set between the pressure inside the building 10 and the pressure outside the building. It is possible to maintain a stable positive pressure in the building 10 at all times. In this case, it is desirable to set the pressure difference between the pressure inside the building 10 and the pressure outside the building to about 5 Pa to 10 Pa. Further, when the atmospheric pressure in the building 10 fluctuates due to an opening / closing operation of a door (not shown) provided in the building 10, the backflow prevention function of the differential pressure adjusting means 9 operates following this, so Intrusion of outside air from the paths 5, 6, 7, and 8 can be prevented.
また、排気経路5,6,7,8から排出される空気量を差圧調節手段9で増減させることにより、建物10内の気圧を昇降させることもできるので、建物外の気圧などが変化した場合でも、汚染物質の侵入防止機能を適切な状態に設定することができる。さらに、差圧調節手段9は逆流防止手段も有するので、給気手段15の故障や停止などの原因で建物10内の正圧が維持できなくなった場合、あるいは強風などにより排気経路5,6,7,8に向かって外気が吹き込むような事態が生じた場合でも、汚染物質を含む外気の建物10内への侵入を防止することができる。   In addition, the air pressure inside the building 10 can be increased or decreased by increasing or decreasing the amount of air discharged from the exhaust paths 5, 6, 7 and 8 by the differential pressure adjusting means 9, so that the air pressure outside the building has changed. Even in this case, it is possible to set the contaminant intrusion prevention function to an appropriate state. Furthermore, since the differential pressure adjusting means 9 also has a backflow preventing means, when the positive pressure in the building 10 cannot be maintained due to a failure or stop of the air supply means 15, or due to strong winds, etc., the exhaust paths 5, 6, Even when a situation occurs in which outside air blows in toward 7, 8, it is possible to prevent the outside air containing contaminants from entering the building 10.
なお、逆流防止機能を有する差圧調節手段9は、特に限定しないので、予め設定された一定圧力以上で開放状態を保ち、一定圧力未満で閉鎖する機能を有するものを使用することができる。また、逆流防止機能を有する差圧調節手段9は、圧力差により開閉する羽根にウエイトなどを取り付け、一定圧力差以上で開放し、圧力差がなくなると自重で閉止する機構をもつ差圧開閉手段などを好適に使用することができる。設定圧力はウエイトの取り付け個数などで任意に設定できるものでもよい。この場合、ウエイト個数が増えれば開放する際の圧力が高くなり、外気との差圧を大きくとることができ、ウエイト個数が減れば開放圧力が下がり、外気との差圧を小さくすることができる。   The differential pressure adjusting means 9 having a backflow preventing function is not particularly limited, and those having a function of maintaining an open state at a predetermined pressure or higher and closing at a predetermined pressure or lower can be used. The differential pressure adjusting means 9 having a backflow prevention function is a differential pressure opening / closing means having a mechanism in which a weight or the like is attached to a blade that opens and closes due to a pressure difference, opens when a pressure difference exceeds a certain level, and closes with its own weight when the pressure difference disappears. Etc. can be used suitably. The set pressure may be set arbitrarily according to the number of attached weights. In this case, if the number of weights increases, the pressure at the time of opening increases, and the differential pressure with the outside air can be increased. If the number of weights decreases, the opening pressure decreases and the pressure difference with the outside air can be reduced. .
そのほか、排気経路5,6,7,8に排気ファン(図示せず)を設けて第1種換気方式の24時間換気を行うこともできる。この場合も、開口部10bからの給気量が、排気経路5,6,7,8からの排気量よりも多くなるように設定すれば、第1種換気方式により計画的な換気を実現しつつ、建物10内を常に正圧に保つことができる。また、建物10内の気圧と建物外の気圧との間に設定されている圧力差を変更する場合は前記排気ファンの回転数を変更することによっても対応可能である。   In addition, it is also possible to provide an exhaust fan (not shown) in the exhaust paths 5, 6, 7, and 8 to perform 24-hour ventilation of the first type ventilation system. Also in this case, if the amount of air supplied from the opening 10b is set to be larger than the amount of exhaust from the exhaust paths 5, 6, 7 and 8, systematic ventilation is realized by the first type ventilation method. However, the inside of the building 10 can always be kept at a positive pressure. In addition, when the pressure difference set between the pressure inside the building 10 and the pressure outside the building is changed, it can be dealt with by changing the rotation speed of the exhaust fan.
本実施形態において建物10は高気密・高断熱構造であるが、これに限定しないので、中気密・中断熱構造の建物などにおいても本発明の空調システムを施工することが可能であり、そのような建物においても、建物内を常に静寂かつ快適で清浄な雰囲気に保つことができる。   In the present embodiment, the building 10 has a high airtightness / high heat insulation structure, but is not limited to this, and therefore the air conditioning system of the present invention can be constructed even in a medium airtight / medium heat insulation structure, etc. Even in a modern building, the interior can always be kept quiet, comfortable and clean.
次に、図3に基づいて、本発明の第2実施形態である空調システム200について説明する。なお、図3に示す空調システム200において、図1に示す空調システム100の構成部分と同様の構造、機能を有する部分は図1中の符号と同じ符号を付して説明を省略する。   Next, the air conditioning system 200 which is 2nd Embodiment of this invention is demonstrated based on FIG. In the air conditioning system 200 shown in FIG. 3, parts having the same structure and function as the constituent parts of the air conditioning system 100 shown in FIG. 1 are denoted by the same reference numerals as those in FIG.
図3に示す空調システム200においては、通気経路19は給気経路14と連通しており、建物10の1階天井部C1と2階床部F2との間に気密断熱状のダクトレス空間を形成し、このダクトレス空間を通気経路19とし、1階側の部屋1,2の給気口21aが部屋1,2の天井面1c,2cに設けられている。   In the air conditioning system 200 shown in FIG. 3, the ventilation path 19 communicates with the air supply path 14, and an airtight and heat insulating ductless space is formed between the first-floor ceiling C <b> 1 and the second-floor floor F <b> 2 of the building 10. And this ductless space is made into the ventilation path 19, and the air inlet 21a of the rooms 1 and 2 on the first floor side is provided in the ceiling surfaces 1c and 2c of the rooms 1 and 2.
1階側の部屋1,2の天井面1c,2cは通気経路19(ダクトレス空間)に接しているため、これらの場所に、給気口21aを設ければ、給気口21aと通気経路19とが最短距離で連通するため、施工の簡略化を図ることができる。また、1階天井部C1と2階床部F2との間のみをダクトレス空間として使用しているため、気密断熱処理など、ダクトレス空間を構築するための処理も必要最小限で済む。その他の部分の構造、機能などについては図1に示す空調システム100と同様である。   Since the ceiling surfaces 1c and 2c of the rooms 1 and 2 on the first floor are in contact with the ventilation path 19 (ductless space), if the air supply opening 21a is provided at these places, the air supply opening 21a and the ventilation path 19 are provided. Since it communicates with the shortest distance, construction can be simplified. Further, since only the space between the first-floor ceiling portion C1 and the second-floor floor portion F2 is used as the ductless space, processing for constructing the ductless space, such as airtight heat insulation processing, can be minimized. The structure and functions of other parts are the same as those of the air conditioning system 100 shown in FIG.
次に、図4に示す空調システム300においては、第1,2実施形態である空調システム100,200の場合と同様、2階床部F2と1階天井部C1との間に気密断熱状のダクトレス空間を形成し、このダクトレス空間を通気経路39としている。この場合、屋外に設置された給気手段(図示せず)と通気経路39とは、適宜、断熱処理が施されたダクト38などで接続されている。   Next, in the air conditioning system 300 shown in FIG. 4, as in the case of the air conditioning systems 100 and 200 according to the first and second embodiments, an airtight heat insulating shape is provided between the second floor portion F2 and the first floor ceiling portion C1. A ductless space is formed, and this ductless space is used as a ventilation path 39. In this case, an air supply means (not shown) installed outdoors and the ventilation path 39 are appropriately connected by a duct 38 or the like that has been subjected to heat insulation.
図4は冬期の運転状態を示しており、新鮮な外気は屋外に設置した給気手段であるファンコイルユニット(例えば、図1に示す給気手段15及び熱交換器17を一体化した機材)によってダクトレス空間39に給気され、2階側の部屋4の床面4fであってドア4bの前に設置された給気口21から部屋4内へ供給される。この場合、給気口21からの給気と放熱器(図示せず)による暖房に加え、床面4fからの輻射効果も生じるので、優れた暖房効果を得ることができる。   FIG. 4 shows the operating state in winter, and fresh outside air is a fan coil unit that is an air supply means installed outdoors (for example, equipment in which the air supply means 15 and the heat exchanger 17 shown in FIG. 1 are integrated). The air is supplied to the ductless space 39 and supplied into the room 4 from the air supply port 21 provided on the floor surface 4f of the room 4 on the second floor side and in front of the door 4b. In this case, in addition to air supply from the air supply port 21 and heating by a radiator (not shown), a radiation effect from the floor surface 4f is also produced, so that an excellent heating effect can be obtained.
次に、図5に示す空調システム400においては、2階床部F2と1階天井部C1との間に形成されたダクトレス空間を通気経路49とするとともに、前記ダクトレス空間に気密性及び断熱性を持たせる手段として、発泡断熱構造を採用している。発泡断熱構造は、合成樹脂系の断熱材を発泡させた発泡断熱材41を建物40の内側に吹き付けることによって形成されている。具体的には、2階床部F2を構築した後に、発泡断熱材41を吹き付け、その後、1階天井部C1を構築することによって発泡断熱構造を形成することができるが、これに限定するものではない。   Next, in the air conditioning system 400 shown in FIG. 5, the ductless space formed between the second floor portion F2 and the first floor ceiling portion C1 is used as the ventilation path 49, and the ductless space is airtight and heat insulating. A foam insulation structure is adopted as a means for providing the heat resistance. The foam heat insulating structure is formed by blowing a foam heat insulating material 41 obtained by foaming a synthetic resin heat insulating material to the inside of the building 40. Specifically, after the second-floor floor portion F2 is constructed, the foam insulation material 41 is sprayed, and then the first-floor ceiling portion C1 can be constructed to form a foam insulation structure, but this is limited to this. is not.
発泡断熱材41は建物40内の隙間にも確実に充填されるので、断熱機能を確保しつつ建物10の気密性を向上させることができる。また、2階床部F2と1階天井部C1との間に形成されたダクトレス空間49を給気経路の一部とすることにより、室内に供給される新鮮な外気の熱ロスを最小限に抑えることができる。   Since the foam heat insulating material 41 is reliably filled in the gaps in the building 40, the airtightness of the building 10 can be improved while ensuring the heat insulating function. Further, by making the ductless space 49 formed between the second-floor floor portion F2 and the first-floor ceiling portion C1 part of the air supply path, heat loss of fresh outdoor air supplied to the room is minimized. Can be suppressed.
なお、建物の壁部、天井部、床部の内部に空調空気を流通させるようにすれば、建物の躯体(構造部分)の風通しが良くなり、結露などが発生し難くなるので、建物の長寿命化を図ることができるほか、ダクトレス空間も空調されることとなるので、ダクトレス空間と居室との温度差がなくなり、居室の壁、天井、床などの面も室温に近くなる結果、温度差がなくなって快適な空調を実現することができる。   If air conditioned air is circulated inside the walls, ceilings, and floors of the building, the building's housing (structure) will be more ventilated and condensation will not easily occur. In addition to extending the service life, the ductless space is also air-conditioned, eliminating the temperature difference between the ductless space and the room, and the walls, ceiling, floor, and other surfaces of the room close to room temperature. This eliminates the need for comfortable air conditioning.
なお、図1〜図5に基づいて説明した実施形態は本発明に係る空調システムを例示したものであり、本発明の空調システムは前述した実施形態に限定されない。   In addition, embodiment described based on FIGS. 1-5 illustrates the air conditioning system which concerns on this invention, and the air conditioning system of this invention is not limited to embodiment mentioned above.
本発明の空調システムは、戸建て住宅や集合住宅などの各種建築物における空調手段として、建築・建設産業の分野などにおいて広く利用することができる。   The air conditioning system of the present invention can be widely used in the field of construction and construction industries as air conditioning means in various buildings such as detached houses and apartment houses.
