Description

本発明は、給気流と排気流間で熱交換を行う天井埋込型の熱交換換気装置に関するものである。   The present invention relates to a ceiling-embedded heat exchange ventilator that performs heat exchange between a supply air flow and an exhaust air flow.
熱交換換気装置の中には、室内空気の流れである排気流を、熱交換器を迂回するバイパスに流し、熱交換をしない給排気による換気も行えるようにしたものがある。バイパスの開閉は、電動ダンパによって行われるようになっている。春とか秋とかの中間季には、バイパスを使った普通換気を行うことができる。なお、この種の従来技術としては特許文献1に示されているものがある。   In some heat exchange ventilators, an exhaust flow that is a flow of room air is passed through a bypass that bypasses the heat exchanger so that ventilation by supply and exhaust without heat exchange can be performed. The bypass is opened and closed by an electric damper. In mid-season such as spring or autumn, normal ventilation using bypass can be performed. In addition, there exists a thing shown by patent document 1 as this type of prior art.

従来の熱交換換気装置は、換気モード設定部の設定によって給排気流間で連続的な熱交換をして室内を換気する熱交換換気モードか、電動ダンパでバイパスを開き、排気流を熱交換器を迂回して通し、給排気流間での熱交換を行わない給排気による普通換気モードのいずれかを設定することができる。そして、外気温を検知する外気温検知センサを備え、外気温が所定温度より低いときには、普通換気モードで運転していても、強制的に電動ダンパを動作させてバイパスを閉じ、熱交換換気を行うようになっている。しかしながら、今日、住宅の高気密化が進み、住宅全体を常時換気する換気システムが提案される中で、そうした換気システムの中核をなす換気装置としては機能的ではない。   The conventional heat exchange ventilator is either a heat exchange ventilation mode that ventilates the room by continuously exchanging heat between the supply and exhaust flow according to the setting of the ventilation mode setting unit, or opens a bypass with an electric damper and heat exchanges the exhaust flow It is possible to set one of the normal ventilation modes by supply / exhaust that does not exchange heat between the supply / exhaust flows, bypassing the vessel. An outside air temperature detection sensor that detects the outside air temperature is provided, and when the outside air temperature is lower than the predetermined temperature, the electric damper is forcibly operated to close the bypass even when operating in the normal ventilation mode. To do. However, today, as the airtightness of houses is advanced and a ventilation system that constantly ventilates the whole house is proposed, it is not functional as a ventilator that forms the core of such a ventilation system.
このような換気システムでは、居間等の居室から給気を行い、サニタリーゾーンから排気を行うような構成が採られることが多い。サニタリーゾーンの中でも浴室は、トイレや洗面所とは異なり、常時換気には適さない。入浴時には排気による換気で寒さを覚えたり、夏季に浴室の暖気を熱交換器を通じて熱交換換気すると、冷房負荷が増加してしまい、換気システムとしては好適とは言えない。   Such a ventilation system is often configured to supply air from a living room or the like and exhaust air from a sanitary zone. Even in the sanitary zone, the bathroom is not suitable for ventilation at all times, unlike the toilet and washroom. When bathing, the coldness is felt by exhaust ventilation, or if the bathroom warm air is heat exchange ventilated through a heat exchanger in the summer, the cooling load increases, which is not suitable as a ventilation system.

A part of the air supply passage is constituted by a secondary passage of a built-in heat exchanger. A part of the exhaust passage is constituted by a primary passage of the heat exchanger. The air supply passage is provided with an air supply blower that forms a supply airflow passing through the secondary passage of the heat exchanger. The exhaust passage is provided with an exhaust fan for forming an exhaust flow passing through the primary passage of the heat exchanger.
給気通路は、室外吸込口を入口端とし、室内吹出口を出口端とする一連の風路であり、室外吸込口は、ダクトを介して屋外に、室内吹出口は、ダクトを介して室内にそれぞれ連絡される。排気通路は、室内吸込口を入口端とし、室外吹出口を出口端とする一連の風路であり、室内吸込口は、一つを除いて他のものはダクトを介して室内に連絡され、室外吹出口は、ダクトを介して屋外に連絡される。排気通路の室内吸込口は、複数個が設けられ、そのうちの一つを天井面に臨ませるグリル付きの開口とし、他の室内吸込口についてはダクトで室内と連絡できるようにし、グリル付き開口を除く室内吸込口の特定の一つには熱交換器の一次通路を迂回するバイパス通路が連絡されている。連絡部には電動ダンパが設けられている。この電動ダンパの動作により、バイパス通路を閉止し、熱交換器の一次通路に通じる当該室内吸込口と続く排気通路部分を開放することができる。また、電動ダンパの動作により、バイパス通路を開放し、熱交換器の一次通路に通じる排気通路部分を閉止することができ、さらにバイパス通路を閉止し、熱交換器の一次通路に通じる排気通路部分も閉止することができる。   The air supply passage is a series of air passages having an outdoor suction port as an inlet end and an indoor outlet as an outlet end. The outdoor suction port is outdoors via a duct, and the indoor outlet is indoors via a duct. Will be contacted respectively. The exhaust passage is a series of air passages having an indoor suction port as an inlet end and an outdoor outlet as an outlet end, and the indoor suction port except one is connected to the room via a duct, The outdoor outlet is connected to the outside through a duct. There are a plurality of indoor air inlets in the exhaust passage, one of which has an opening with a grille facing the ceiling surface, and the other indoor air inlets can be communicated with the room by a duct. A specific one of the indoor suction ports is connected to a bypass passage that bypasses the primary passage of the heat exchanger. An electric damper is provided in the communication part. By the operation of the electric damper, the bypass passage can be closed, and the exhaust passage portion connected to the indoor suction port leading to the primary passage of the heat exchanger can be opened. In addition, by the operation of the electric damper, the bypass passage can be opened and the exhaust passage portion leading to the primary passage of the heat exchanger can be closed, and further, the exhaust passage portion closing the bypass passage and leading to the primary passage of the heat exchanger Can also be closed.
この熱交換換気装置は、住宅の天井裏等に設置し、グリル付きの室内吸込口を廊下等の天井面に望んで開口させ、他の室内吸込口と室内吹出口をダクトでそれぞれ室内に連絡させ、室外吸込口と室外吹出口を屋外に連絡させることによって住宅全体を常時換気する換気システムが構築できる。室内吸込口のバイパス通路に通じるものは、浴室に連絡させ、他の室内吸込口は、分岐したダクトによりトイレと洗面所に連絡させる。室内吹出口は、居室に連絡させる。給気用送風機と排気用送風機を運転すれば、居室から外気が供給され、廊下、トイレ、洗面所、浴室を通じて住宅の空気が屋外へ排気される。そして、給気流と排気流とは熱交換器において連続して熱交換され、状態量の変動の少ない熱交換換気が実施できる。このとき、トイレと洗面所については常に熱交換器を通して排気されるが、浴室については、電動ダンパを動作させ、熱交換器に通じる排気通路を閉止し、バイパス通路を開放させることにより、熱交換器を通さずに排気することができる。また、電動ダンパの動作により、バイパス通路を閉止し、熱交換器の一次通路に通じる排気通路部分も閉止し、浴室の換気そのものを停止させることができる。これにより、浴室については、排気による換気を停止させることができ、冬季における入浴時等に換気で寒さを覚えたりすることなく、夏季にはバイパス通路により浴室の暖気を、熱交換器を通さずに排気することができ、住宅全体を常時換気する、無駄なエネルギー消費の少ない換気システムが構築できる。   This heat exchange ventilator is installed on the ceiling of a house, etc., and opens an indoor air inlet with a grill on the ceiling surface of a corridor, etc., and connects the other indoor air inlets and indoor air outlets to the room with ducts. The ventilation system that constantly ventilates the entire house can be constructed by letting the outdoor inlet and the outdoor outlet communicate with the outside. Those that lead to the bypass passage of the indoor suction port are connected to the bathroom, and the other indoor suction ports are connected to the toilet and the washroom through a branched duct. The indoor outlet is connected to the living room. When the air supply fan and the exhaust fan are operated, outside air is supplied from the living room, and the air in the house is exhausted to the outside through the corridor, toilet, washroom, and bathroom. The supply air flow and the exhaust flow are continuously heat-exchanged in the heat exchanger, and heat exchange ventilation with little variation in the state quantity can be performed. At this time, the toilet and the washroom are always exhausted through the heat exchanger, but in the bathroom, the electric damper is operated, the exhaust passage leading to the heat exchanger is closed, and the bypass passage is opened to exchange heat. It is possible to exhaust without passing through the vessel. In addition, the operation of the electric damper closes the bypass passage and also closes the exhaust passage portion leading to the primary passage of the heat exchanger, thereby stopping the ventilation of the bathroom itself. As a result, ventilation by the exhaust can be stopped for the bathroom, and it does not feel cold due to ventilation during bathing in winter, etc. This makes it possible to construct a ventilation system that can exhaust air and constantly ventilate the entire house with less wasteful energy consumption.

この熱交換換気装置1は、図8のフローチャートに示すように動作する。即ち、電源が投入される(ステップ♯1)と、ステップ♯2で給気用送風機9及び排気用送風機11の運転が開始され、ステップ♯3へすすむ。ステップ♯3では、モード設定スイッチ30〜32の設定がどれかが判定され、熱交換換気モードであればステップ♯4でそのように電動ダンパ20を動かし、普通換気モードであればステップ♯5でそのように電動ダンパ20を動かし、換気停止モードであればステップ♯6でそのように電動ダンパ20を動かしてステップ♯7へすすむ。ステップ♯7では給気用送風機9の動作時間を積算してステップ♯8で積算時間Tが所定の基準時間T0を越えたかどうかを判定する。越えていなければステップ♯2へ戻り、越えていればステップ♯9でスイッチの発光素子を点灯させエアーフィルタ27の保守時期であることを表示部35で報知して処理を終了する。   The heat exchange ventilator 1 operates as shown in the flowchart of FIG. That is, when the power is turned on (step # 1), the operation of the air supply blower 9 and the exhaust blower 11 is started in step # 2, and the process proceeds to step # 3. In step # 3, it is determined which of the mode setting switches 30 to 32 is set. In the heat exchange ventilation mode, the electric damper 20 is moved in step # 4, and in the normal ventilation mode, in step # 5. The electric damper 20 is moved in such a manner, and if it is in the ventilation stop mode, the electric damper 20 is moved in that way in step # 6 and the process proceeds to step # 7. In step # 7, the operating time of the air supply blower 9 is integrated, and in step # 8, it is determined whether or not the integrated time T has exceeded a predetermined reference time T0. If not, the process returns to step # 2, and if it exceeds, the light emitting element of the switch is turned on in step # 9 to notify the display unit 35 that the maintenance time for the air filter 27 is reached, and the process is terminated.
この熱交換換気装置1は、図9に示すように住宅の天井裏空間の天上面に沿って設置し、室内吸込口15は廊下L5等の天上面に臨んで開口させ、室内吸込口16,17と室内吹出口14をダクト2でそれぞれ室内に連絡させ、室外吸込口13と室外吹出口18を屋外に連絡させることによって住宅全体を常時換気する換気システムが構築できる。室内吸込口17のバイパス通路19に通じるものは、浴室L1に連絡させ、他の室内吸込口16は、ダクト2によりトイレL2と洗面所L3に連絡させる。室内吹出口14は、居室L4に連絡させる。給気用送風機9と排気用送風機11を運転すれば、居室L4から外気が供給され、ガラリ等を通じて廊下L5、トイレL2、洗面所L3、浴室L1から住宅の空気が屋外へ排気される。そして、給気流と排気流とは熱交換器6において連続して熱交換され、状態量の変動の少ない熱交換換気が実施できる。このとき、トイレL2と洗面所L3については常に熱交換器6を通して排気されるが、浴室L1については、バイパス通路19を、電動ダンパ20を動作させ、熱交換器6に通じる排気通路部分21を閉止し、バイパス通路19を開放させることにより、熱交換器6を通さずに排気することができる。また、電動ダンパ20の動作により、バイパス通路19を閉止し、熱交換器6の一次通路8に通じる排気通路部分21も閉止し、浴室L1の換気そのものを停止させることができる。これにより、浴室L1については、排気による換気を停止させることができ、冬季における入浴時等に換気で寒さを覚えたりすることなく、夏季にはバイパス通路19により浴室L1の暖気を熱交換器6を通さずに排気することができ、住宅全体を常時換気する、無駄なエネルギー消費の少ない換気システムが構築できる。この換気システムによれば、浴室換気の停止時には、廊下L5のグリル15Aの付いた室内吸込口15があるため、他のトイレL2等の排気が増えすぎて、肌寒さ等を感じさせずにすむ。   As shown in FIG. 9, the heat exchange ventilator 1 is installed along the top surface of the ceiling space of the house, and the indoor suction port 15 is opened facing the top surface of the hallway L5 or the like, and the indoor suction ports 16, The ventilation system which always ventilates the whole house can be constructed | assembled by making 17 and the indoor blower outlet 14 each connect with the room | chamber interior by the duct 2, and making the outdoor suction inlet 13 and the outdoor blower outlet 18 connect the outdoors. What leads to the bypass passage 19 of the indoor suction port 17 is connected to the bathroom L1, and the other indoor suction port 16 is connected to the toilet L2 and the toilet L3 by the duct 2. The indoor outlet 14 is connected to the living room L4. When the air supply blower 9 and the exhaust blower 11 are operated, outside air is supplied from the living room L4, and the air in the house is exhausted to the outdoors from the corridor L5, the toilet L2, the washroom L3, and the bathroom L1 through the gallery. The supply air flow and the exhaust air flow are continuously heat-exchanged in the heat exchanger 6, and heat exchange ventilation with little variation in the state quantity can be performed. At this time, the toilet L2 and the washroom L3 are always exhausted through the heat exchanger 6, but the bathroom L1 has the bypass passage 19 and the exhaust passage portion 21 that leads to the heat exchanger 6 by operating the electric damper 20. By closing and opening the bypass passage 19, it is possible to exhaust without passing through the heat exchanger 6. Further, by the operation of the electric damper 20, the bypass passage 19 is closed, the exhaust passage portion 21 leading to the primary passage 8 of the heat exchanger 6 is also closed, and the ventilation itself of the bathroom L1 can be stopped. As a result, the ventilation by the exhaust can be stopped for the bathroom L1, and the warm air in the bathroom L1 is transferred to the heat exchanger 6 by the bypass passage 19 in the summer without having to feel the cold during the bathing in the winter. A ventilation system that can exhaust air without passing through it and constantly ventilate the entire house and consumes less energy is built. According to this ventilation system, when the bathroom ventilation is stopped, since there is the indoor suction port 15 with the grill 15A of the hallway L5, the exhaust of the other toilets L2 and the like increases too much, so that it does not feel chilly. .
