Here, the first office 10, the second office 20 and the meeting room 30 are exclusive parts, and the hot water supply room 40 and the toilet 50 are common parts.
　熱交換換気装置１１，２１の排気は、共用部分に排出される。なお、熱交換換気装置１１，２１，２２の排気とは、第１事務室１０又は第２事務室２０から吸い出され、外気空気との間で熱交換がなされた後の空気である。 Exhaust gas from the heat exchange ventilators 11 and 21 is discharged to the common part. In addition, the exhaust of the heat exchange ventilators 11, 21, and 22 is air after being sucked from the first office 10 or the second office 20 and subjected to heat exchange with the outside air.
　熱交換換気装置１１，２１，２２，３１及び局所排気装置４１，５１，５２は、通信ケーブル６０で接続されている。熱交換換気装置１１，２１，２２，３１及び局所排気装置４１，５１，５２は、通信ケーブル６０を通じて他の機器に運転状態情報を送信する。運転状態情報とは、装置が運転しているか否かを示す情報及び運転強度の情報を含む。熱交換換気装置１１，２１，２２，３１及び局所排気装置４１，５１，５２の運転状態の監視及び操作は、監視用操作盤７０を通じて行うことが可能である。 The heat exchange ventilators 11, 21, 22 and 31 and the local exhaust devices 41, 51 and 52 are connected by a communication cable 60.

Monitoring and operation of the operating states of the heat exchange ventilators 11, 21, 22, 31 and the local exhaust devices 41, 51, 52 can be performed through the monitoring control panel 70.
　図１中に矢印とともに示す数値は、給気量及び排気量を示している。図１に示すように、建物全体では、給気量及び排気量はともに１９５０ｍ３／ｈであるため、給排気のバランスはとれている。 Numerical values shown with arrows in FIG. 1 indicate the air supply amount and the air discharge amount. As shown in FIG. 1, in the entire building, since both the air supply amount and the air discharge amount are 1950 m 3 / h, the air supply and discharge are balanced.
　図３は、実施の形態１に係る換気システムに適用される熱交換換気装置の斜視図である。なお、図３では、熱交換換気装置１１の筐体の一部を切り欠いて内部を可視化して示している。熱交換換気装置１１は、対向する側面の一方に室内側の吸込口１０４と吹出口１０６とを有し、他方に室外側の吸込口１０５と吹出口１０７とを有する箱体１０１内に、吸込口１０４，１０５と吹出口１０７，１０６との間に設けた熱交換器１１２において互いに交差し熱交換するよう設けられた給気風路１０９及び排気風路１０８とを備えている。 FIG. 3 is a perspective view of a heat exchange ventilator applied to the ventilation system according to the first embodiment. In FIG. 3, a part of the casing of the heat exchange ventilator 11 is cut away to visualize the inside. The heat exchange ventilator 11 has the suction port 104 and the blowout port 106 on the indoor side on one of the opposing side surfaces, and the suction in the box 101 having the suction port 105 and the blowout port 107 on the outdoor side on the other. In the heat exchanger 112 provided between the ports 104 and 105 and the outlets 107 and 106, there are provided an air supply path 109 and an exhaust air path 108 which are provided so as to intersect each other for heat exchange.
　排気風路１０８には、排気流を形成する排気用送風機１１０が設置される。給気風路１０９には、給気流を形成する給気用送風機１１１が設置される。排気用送風機１１０及び給気用送風機１１１は、羽根１２１及び電動機１２６を備える。羽根１２１及び電動機１２６は、羽根ケーシング１１６に収容されている。箱体１０１には、給気流と排気流との間で熱交換を行う熱交換器１１２が設置されている。熱交換器１１２は、箱体１０１に形成されている開口１１５から挿抜可能となっている。 In the exhaust air passage 108, an exhaust blower 110 for forming an exhaust flow is installed. In the supply air passage 109, a supply air blower 111 for forming a supply flow is installed. The exhaust fan 110 and the air supply fan 111 include blades 121 and an electric motor 126. The blades 121 and the motor 126 are accommodated in a blade casing 116. The box body 101 is provided with a heat exchanger 112 that exchanges heat between the charge air flow and the exhaust gas flow. The heat exchanger 112 can be inserted and removed from the opening 115 formed in the box 101.
　熱交換換気装置１１において、熱交換器１１２を利用した空調換気については、排気用送風機１１０及び給気用送風機１１１を運転することにより、室内空気は、ダクトを介して吸込口１０４から矢印Ａのように吸い込まれ、熱交換器１１２及び排気風路１０８を矢印Ｂのように通り、排気用送風機１１０により吹出口１０７から矢印Ｃのように吹き出される。 In the heat exchange ventilator 11, for air conditioning ventilation using the heat exchanger 112, by operating the exhaust blower 110 and the air supply blower 111, the indoor air can flow from the inlet 104 to the arrow A via the duct. Thus, the air is sucked and flows through the heat exchanger 112 and the exhaust air passage 108 as shown by arrow B, and is blown out from the outlet 107 by the exhaust blower 110 as shown by arrow C.
　また、ダクトを介して吸込口１０５から矢印Ｄのように吸い込まれ、熱交換器１１２及び給気風路１０９を矢印Ｅのように通り、給気用送風機１１１により吹出口１０６から矢印Ｆのように吹き出され、ダクトを介して室内に給気される。このとき、熱交換器１１２では排気流と給気流との間で熱交換が行われ、排気熱を回収して冷暖房負荷を軽減する。なお、排気用送風機１１０及び給気用送風機１１１の運転は、制御部１１７により制御される。 Also, it is drawn in as arrow D from the suction port 105 through the duct, passes through the heat exchanger 112 and the air supply air passage 109 as arrow E, and as shown by arrow F from the air outlet 106 by the air supply blower 111. The air is blown out and supplied into the room through the duct. At this time, in the heat exchanger 112, heat exchange is performed between the exhaust flow and the charge air flow, and the exhaust heat is recovered to reduce the cooling and heating load. The operation of the exhaust blower 110 and the air supply blower 111 is controlled by the control unit 117.
　なお、熱交換換気装置２１，２２，３１も熱交換換気装置１１と同様の構成を有する。また、給気用送風機２１１，２２１，３１１は、給気用送風機１１１と同様であり、排気用送風機２１０，２２０，３１０は、排気用送風機１１０と同様である。また、熱交換器２１２，２２２，３１２は、熱交換器１１２と同様である。また、制御部２１７，２２７，３１７は、制御部１１７と同様である。 The heat exchange ventilators 21, 22 and 31 also have the same configuration as the heat exchange ventilator 11. Further, the air supply blowers 211, 221 and 311 are the same as the air supply blower 111, and the exhaust air blowers 210, 220 and 310 are the same as the exhaust air blower 110. Also, the heat exchangers 212, 222, 312 are similar to the heat exchanger 112. The control units 217, 227, and 317 are similar to the control unit 117.
　局所排気装置４１は、設置箇所の空気を取り込んで排気流を形成する排気用送風機４１１と、排気用送風機４１１の運転強度を変更することによって換気風量を変化させる制御部４１２とを備える。局所排気装置４１は、共用部分に設置されており、設置箇所の局所排気を行う。なお、局所排気装置５１，５２も局所排気装置４１と同様の構成を有し、共用部分に設置される。また、排気用送風機５１１，５２１は排気用送風機４１１と同様であり、制御部５１２，５２２は、制御部４１２と同様である。 The local exhaust device 41 includes an exhaust blower 411 that takes in the air at the installation location to form an exhaust flow, and a control unit 412 that changes the ventilation air volume by changing the operating intensity of the exhaust blower 411. The local exhaust device 41 is installed in the common part, and performs local exhaust of the installation location. The local exhaust devices 51 and 52 also have the same configuration as the local exhaust device 41, and are installed in the common part. The exhaust blowers 511 and 521 are similar to the exhaust blower 411, and the control units 512 and 522 are similar to the control unit 412.
　図４は、実施の形態１に係る換気システムにおいて一部の熱交換換気装置を停止させた状態を示す図である。在室人数が減るなどの理由で第１事務室１０の熱交換換気装置１１を停止させると、建物全体では、給気量は９５０ｍ３／ｈとなり、排気量は１９５０ｍ３／ｈとなり、給排気のバランスが崩れる。実施の形態１に係る換気システム１００は、熱交換換気装置１１を停止させるなどして換気風量が低下し、給気風量及び排気風量が減少する場合、給湯室４０又はトイレ５０に設置された局所排気装置４１，５１，５２の排気量を減らすことで、建物全体での給排気のバランスを整える。建物全体での給排気のバランスを整えることにより、第２事務室２０に設置された熱交換換気装置２１，２２及び会議室３０に設置された熱交換換気装置３１は、給排気のバランスを崩すことなく運用が可能となる。 FIG. 4 is a view showing a state in which a part of the heat exchange ventilator is stopped in the ventilation system according to the first embodiment. If the heat exchange ventilator 11 in the first office 10 is stopped for reasons such as a decrease in the number of people in the room, the amount of air supplied is 950 m 3 / h and the amount of exhaust air is 1950 m 3 / h throughout the building The balance of In the ventilation system 100 according to the first embodiment, the local area installed in the hot water supply room 40 or the toilet 50 when the ventilation air volume decreases by stopping the heat exchange ventilator 11 or the like and the air supply volume and the exhaust air volume decrease. By reducing the displacement of the exhaust devices 41, 51, 52, the balance between air supply and exhaust in the entire building is adjusted. The heat exchange ventilators 21 and 22 installed in the second office 20 and the heat exchange ventilator 31 installed in the conference room 30 break the balance of the supply and exhaust by adjusting the balance of the supply and exhaust throughout the building. Operation is possible without
　なお、局所排気装置４１，５１，５２が停止した場合、連動して熱交換換気装置１１，２１，２２，３１の換気風量を低下させてしまうと、専有部分で必要換気風量が確保できないおそれがあるため、局所排気装置４１，５１，５２が停止しても、専有部分の換気風量は低下させない。 In addition, when local exhaust system 41, 51, 52 stops, if the ventilation air volume of heat exchange ventilators 11, 21, 22, 31 is interlockedly reduced, there is a possibility that the necessary ventilation air volume can not be secured in an exclusive part. Because of the presence, even if the local exhaust devices 41, 51, 52 stop, the ventilation air volume of the exclusive portion is not reduced.
　図５は、実施の形態１に係る換気システムの動作の流れを示すフローチャートである。制御部１１７，２１７，２２７，３１７，４１２，５１２，５２２の動作の流れは全て同じであるため、ここでは制御部４１２を例にして説明する。換気システム１００の運転開始後、ステップＳ１において、制御部４１２は、他の機器の制御部１１７，２１７，２２７，３１７，５１２，５２２から運転状態情報を受信したか否かを監視する。運転状態情報を受信していなければ、ステップＳ１でＮｏとなり、運転状態情報を受信したか否かの監視を継続する。運転状態情報を受信したならば、ステップＳ１でＹｅｓとなり、ステップＳ２において制御部４１２は、専有部分の換気風量が低下するか否かを受信した運転状態情報を基に判断する。 FIG. 5 is a flowchart showing the flow of the operation of the ventilation system according to the first embodiment. The flow of the operations of the control units 117, 217, 227, 317, 412, 512, 522 are all the same, so here, the control unit 412 will be described as an example. After starting operation of the ventilation system 100, in step S1, the control unit 412 monitors whether or not operation state information has been received from the control units 117, 217, 227, 317, 512, 522 of other devices. If the driving state information has not been received, the result of step S1 is No, and the monitoring of whether the driving state information has been received is continued. If the operation state information has been received, the result in step S1 becomes Yes, and in step S2, the control unit 412 determines based on the received operation state information whether the ventilation air volume of the exclusive portion is reduced.
　専有部分の換気風量が低下する場合は、ステップＳ２でＹｅｓとなり、ステップＳ３において制御部４１２は、局所排気装置の制御部であるか否かを判断する。制御部４１２は、局所排気装置の制御部であるため、ステップＳ３でＹｅｓとなり、ステップＳ４において、排気用送風機４１１の運転強度を弱くするか又は停止させ、共用部分の換気風量を低減させる。なお、制御部１１７，２１７，２２７，３１７の場合は、熱交換換気装置の制御部であるため、ステップＳ３でＮｏとなり、ステップＳ１に戻って、他の機器から運転状態情報を受信したか否かの監視を行う。 When the ventilation air volume of the exclusive portion decreases, the result in step S2 is Yes, and in step S3, the control unit 412 determines whether it is the control unit of the local exhaust system. Since the control unit 412 is a control unit of the local exhaust system, the answer in step S3 is Yes, and in step S4, the operation intensity of the exhaust fan 411 is weakened or stopped to reduce the ventilation air volume of the common part. In the case of the control units 117, 217, 227, and 317, since the control unit of the heat exchange ventilator is No in step S3, the process returns to step S1 and whether operating condition information is received from other devices Monitor the
　専有部分の換気風量が低下しない場合は、ステップＳ２でＮｏとなり、ステップＳ１に戻り、制御部４１２は、他の機器の制御部１１７，２１７，２２７，３１７，５１２，５２２から運転状態情報を受信したか否かの監視を行う。 When the ventilation air volume of the exclusive part does not decrease, it becomes No in step S2, returns to step S1, and the control unit 412 receives the operating state information from the control units 117, 217, 227, 317, 512, 522 of the other devices. Monitor whether or not you
　実施の形態１に係る換気システム１００は、専有部分の熱交換換気装置１１，２１，２２，３１の少なくとも一部が運転を停止したり換気風量が低下した場合に、共用部分の局所排気装置４１，５１，５２の排気風量を低下させる。したがって、実施の形態１に係る換気システム１００は、専有部分の換気風量が低下する場合に、建物全体での給排気のバランスを整えることができる。 In the ventilation system 100 according to the first embodiment, when at least a part of the heat exchange ventilators 11, 21, 22, 31 of the exclusive part stops the operation or the ventilation air volume decreases, the local exhaust system 41 of the common part. , 51, 52 reduce the amount of exhaust air. Therefore, the ventilation system 100 according to the first embodiment can balance the air supply and exhaust in the entire building when the ventilation air volume of the exclusive portion decreases.
実施の形態２．
　図６は、本発明の実施の形態２に係る換気システムのブロック図である。実施の形態２に係る換気システム１００は、給排気のバランスよりも換気を優先する設定を記憶する換気優先設定記憶部１１８，２１８，２２８，３１８，４１３，５１３，５２３を有する点で、実施の形態１に係る換気システム１００と相違している。この相違点以外は、実施の形態１に係る換気システム１００と同様であるため、重複する説明は省略する。 Second Embodiment
FIG. 6 is a block diagram of a ventilation system according to a second embodiment of the present invention. The ventilation system 100 according to the second embodiment is implemented in that it has a ventilation priority setting storage unit 118, 218, 228, 318, 413, 513, 523 that stores a setting that prioritizes ventilation over the balance of air supply and exhaust. This is different from the ventilation system 100 according to the first embodiment. Other than this difference, since it is the same as the ventilation system 100 according to the first embodiment, the redundant description will be omitted.
　図７は、実施の形態２に係る換気システムの動作の流れを示すフローチャートである。実施の形態１と同様に、制御部１１７，２１７，２２７，３１７，４１２，５１２，５２２の動作の流れは全て同じであるため、ここでは制御部１１７を例にして説明する。ステップＳ１及びステップＳ２は、実施の形態１と同様である。専有部分の換気風量が低下する場合は、ステップＳ２でＹｅｓとなり、ステップＳ１３において制御部１１７は、給排気のバランスよりも換気を優先する設定が換気優先設定記憶部１１８に記憶されているか否かを確認する。給排気のバランスよりも換気を優先する設定が換気優先設定記憶部１１８に記憶されていれば、ステップＳ１３でＹｅｓとなり、ステップＳ１４において、制御部１１７は、熱交換換気装置の制御部であるか否かを判断する。制御部１１７は、熱交換換気装置の制御部であるため、ステップＳ１４でＹｅｓとなり、ステップＳ１５において、制御部１１７は、給気用送風機１１１のみを動かし、専有部分の給気風量を維持する。なお、制御部４１２，５１２，５２２の場合は、局所排気装置の制御部であるため、ステップＳ１４でＮｏとなり、ステップＳ１に戻る。給排気のバランスよりも換気を優先する設定が換気優先設定記憶部１１８に記憶されていなければ、ステップＳ１３でＮｏとなり、ステップＳ３に進む。ステップＳ３及びステップＳ４は、実施の形態１と同様である。 FIG. 7 is a flowchart showing the flow of the operation of the ventilation system according to the second embodiment. As in the first embodiment, the flow of the operations of the control units 117, 217, 227, 317, 412, 512, 522 are all the same, and therefore, the control unit 117 will be described as an example. Steps S1 and S2 are the same as in the first embodiment. When the ventilation air volume of the exclusive portion decreases, Yes in step S2, and in step S13, the control unit 117 stores in the ventilation priority setting storage unit 118 a setting that prioritizes ventilation over the balance of air supply and exhaust. Confirm. If the setting to prioritize ventilation over the balance of air supply and discharge is stored in the ventilation priority setting storage unit 118, Yes is determined in step S13, and in step S14, is the control unit 117 a control unit of a heat exchange ventilator? Decide whether or not. Since the control unit 117 is a control unit of the heat exchange ventilator, the answer in step S14 is Yes, and in step S15, the control unit 117 moves only the air supply blower 111 to maintain the air supply volume of the exclusive portion. In the case of the control units 412, 512, and 522, since the control unit is the control unit of the local exhaust device, the determination in step S14 is No, and the process returns to step S1. If the setting that prioritizes ventilation over the balance of air supply and exhaust is not stored in the ventilation priority setting storage unit 118, No is obtained in step S13, and the process proceeds to step S3. Steps S3 and S4 are the same as in the first embodiment.
　実施の形態２に係る換気システム１００は、換気優先設定記憶部１１８，２１８，２２８，３１８，４１３，５１３，５２３に給排気のバランスよりも換気を優先する設定が記憶されていれば、熱交換換気装置１１，２１，２２，３１の給気用送風機１１１，２１１，２２１，３１１を動かして給気風量を維持するため、専有部分の換気を確実に行うことができる。 In the ventilation system 100 according to the second embodiment, heat exchange is performed if the ventilation priority setting storage unit 118, 218, 228, 318, 413, 513, 523 stores a setting that prioritizes ventilation over the balance of supply and exhaust. Since the supply air blowers 111, 211, 221, and 311 of the ventilation devices 11, 21, 22, and 31 are operated to maintain the supply air flow rate, ventilation of the exclusive portion can be reliably performed.
実施の形態３．
　図８は、本発明の実施の形態３に係る換気システム１００のブロック図である。実施の形態３に係る換気システム１００は、熱交換換気装置１１，２１，２２，３１が外気温度センサ１１９，１２９，２２９，３１９を備えている点で、実施の形態２に係る換気システム１００と相違する。 Third Embodiment
FIG. 8 is a block diagram of a ventilation system 100 according to the third embodiment of the present invention. The ventilation system 100 according to the third embodiment is different from the ventilation system 100 according to the second embodiment in that the heat exchange ventilators 11, 21, 22, 31 include the outside air temperature sensors 119, 129, 229, 319. It is different.
　実施の形態３に係る換気システム１００は、熱交換換気装置１１，２１，２２，３１の制御部１１７，２１７，２２７，３１７は、外気温度が基準値以下の時に熱交換換気の換気風量を低下させる操作が行われた場合には、換気風量を低下させずに非熱交換換気を行い、外気冷房を実行する。 In the ventilation system 100 according to the third embodiment, the control units 117, 217, 227, and 317 of the heat exchange ventilators 11, 21, 22, and 31 reduce the air flow rate of the heat exchange ventilation when the outside air temperature is lower than the reference value. If an operation is performed, the non-heat exchange ventilation is performed without reducing the ventilation air volume, and the outside air cooling is performed.
　図９、図１０及び図１１は、実施の形態３に係る換気システムにおける運転状態の遷移を示す図である。熱交換換気装置１１，２１，２２，３１が給気風量及び排気風量が大の運転を行い、局所排気装置４１，５１，５２が風量大の運転を行っているとき、建物全体の給排気のバランスが取れている。この状態のときに熱交換換気装置１１の換気風量を低下させる操作が行われると、図９中に矢印Ｇで示すように、熱交換換気装置１１の給気風量及び排気風量が低下し、建物全体での給排気のバランスが取れていない状態に移行する。このとき、給排気のバランスよりも換気を優先する設定が換気優先設定記憶部１１８，２１８，２２８，３１８，４１３，５１３，５２３に記憶されていれば、図９中に矢印Ｈで示すように、熱交換換気装置１１の給気風量は、換気風量を低下させる前の熱交換換気での給気風量に戻され、局所排気装置４１，５１，５２の風量は大のまま維持される。一方、給排気のバランスよりも換気を優先する設定が換気優先設定記憶部１１８，２１８，２２８，３１８，４１３，５１３，５２３に記憶されていない場合には、図９中に矢印Ｉで示すように、局所排気装置４１は風量を小とし、局所排気の換気風量を低下させた状態に移行する。局所排気装置４１の局所排気の換気風量が低下することにより、建物全体の給排気のバランスが取れた状態となる。 FIG. 9, FIG. 10 and FIG. 11 show the transition of the operating state in the ventilation system according to the third embodiment. When the heat exchange ventilators 11, 21, 22, 31 operate with large air supply and exhaust air volumes and the local exhaust devices 41, 51, 52 operate with large air volumes, It is balanced. When the operation to reduce the ventilation air volume of the heat exchange ventilator 11 is performed in this state, the supply air volume and the exhaust air volume of the heat exchange ventilator 11 decrease as shown by the arrow G in FIG. Shift to a state where the overall supply and exhaust balances are not balanced. At this time, as shown by an arrow H in FIG. 9, if the setting to prioritize ventilation over the balance of air supply and discharge is stored in the ventilation priority setting storage unit 118, 218, 228, 318, 413, 513, 523. The supply air volume of the heat exchange ventilator 11 is returned to the supply air volume in the heat exchange ventilation before the reduction of the ventilation air volume, and the volume of the local exhaust devices 41, 51, 52 is maintained large. On the other hand, as shown by an arrow I in FIG. 9, when the setting to prioritize ventilation over the balance of air supply and exhaust is not stored in the ventilation priority setting storage unit 118, 218, 228, 318, 413, 513, 523. In addition, the local exhaust device 41 reduces the air flow and shifts to a state in which the ventilation air flow of the local exhaust is reduced. By reducing the ventilation air volume of the local exhaust of the local exhaust device 41, the air supply and exhaust of the entire building becomes balanced.
　また、局所排気装置４１の換気風量が低下している状態において、熱交換換気装置１１の換気風量を低下させる操作が行われると、建物全体の給排気のバランスは大きく崩れることはないので、熱交換換気装置１１以外の機器は換気風量を変化させず、図１０中に矢印Ｊで示すように、熱交換換気装置１１の換気風量のみが低下した状態に移行する。 Moreover, if the operation to reduce the ventilation air volume of the heat exchange ventilator 11 is performed in a state where the ventilation air volume of the local exhaust system 41 is decreasing, the balance of the air supply and exhaust of the whole building will not be largely disturbed. The devices other than the replacement ventilation device 11 do not change the ventilation air volume, and as shown by the arrow J in FIG. 10, shift to a state where only the ventilation air volume of the heat exchange ventilator 11 is reduced.
　局所排気装置４１の換気風量が低下している状態において、図１０中に矢印Ｋで示すように熱交換換気装置１１，２１，２２の換気風量を低下させる操作が行われると、建物全体の給排気のバランスが大きく崩れることに加え、在室者がおらず換気風量を大きくする必要がないと推定できるため、図１０中に矢印Ｌで示すように、共用部分に設置されている局所排気装置４１，４２，５２の換気風量を低下させた状態に移行する。 When an operation to reduce the ventilation air volume of the heat exchange ventilators 11, 21, and 22 is performed as shown by the arrow K in FIG. 10 in a state where the ventilation air volume of the local exhaust device 41 is decreasing, the entire building is supplied. The local exhaust system installed in the common part, as indicated by an arrow L in FIG. 10, can be estimated because there are no occupants and there is no need to increase the ventilation air volume in addition to the large imbalance of the exhaust. It shifts to the state where the ventilation air volume of 41, 42, 52 was reduced.
　また、図１１に矢印Ｍで示すように、熱交換換気装置１１の換気風量を低下させる操作が行われた場合でも、外気温度が基準値以下であって外気冷房の効果が見込めるならば、図１１中に矢印Ｎで示すように、熱交換換気装置１１，２１，２２，３１は、換気風量を低下させずに非熱交換換気を行う状態に移行し、外気冷房を実行する。 Further, as shown by the arrow M in FIG. 11, even when the operation to reduce the ventilation air volume of the heat exchange ventilator 11 is performed, if the outside air temperature is below the reference value and the effect of the outside air cooling can be expected, As indicated by an arrow N in 11, the heat exchange ventilators 11, 21, 22, 31 shift to a non heat exchange ventilation without reducing the air flow rate, and perform the outside air cooling.
　実施の形態３に係る換気システム１００は、外気温度が基準値以下の場合には、熱交換換気装置１１，２１，２２，３１の換気風量は低下させずに非熱交換換気を行うことで、外気冷房により専有部分の室温を下げることができる。したがって、実施の形態３に係る換気システム１００は、外気温が低い場合には、冷熱源を用いることなく室内の温度を下げ、省エネルギー化を図ることができる。 The ventilation system 100 according to the third embodiment performs non-heat exchange ventilation without reducing the air volume of the heat exchange ventilators 11, 21, 22, 31 when the outside air temperature is equal to or lower than the reference value. Outside air cooling can lower the room temperature of the exclusive portion. Therefore, the ventilation system 100 according to the third embodiment can save energy by lowering the indoor temperature without using a cold heat source when the outside air temperature is low.

That is, in the case where the control unit 117, 217, 227, 317 stores in the ventilation priority setting storage unit 118, 218, 228, 318 the setting for prioritizing ventilation over the balance of supply and exhaust, the supply air volume is When the operation to reduce the ventilation air volume of the heat exchange ventilation in the process of returning to the supply air volume in the heat exchange ventilation before reducing the ventilation air volume and the outside air temperature is below the reference value, the ventilation air volume is reduced A processing circuit is provided which performs processing without heat exchange ventilation. When the control unit 412, 512, 522 detects that the air flow rate of the heat exchange ventilation by the heat exchange ventilator 11, 21, 22, 31 has decreased, processing to reduce the air flow rate of the local exhaust and the ventilation priority setting memory If the settings to prioritize ventilation over the balance of air supply and exhaust are stored in the units 413, 513 and 523, the amount of air flow for heat exchange ventilation by the heat exchange ventilators 11, 21, 22, and 31 has decreased.
