気風量の低下を招いていた。Problems to be Solved by the Invention However, in the configuration of the conventional air conditioning ventilation system, the path for the outside air sucked in by the outside air suction blower 112 to reach the ventilation passage 118 is a total heat exchanger than in the case of sensible heat exchange ventilation. Since there are more connecting passages 132 than during ventilation, there will be a difference in the amount of ventilation air supplied indoors during total heat exchange ventilation and sensible heat exchange ventilation, and the balance between indoor pressure and outdoor pressure will be disrupted, causing doors and windows to close. It became difficult to open and close, and drafts were coming in. In addition, during normal ventilation, a part of the indoor air passes through the first indoor suction port 117, passes through the total heat exchange element 109, and is then exhausted by the indoor air discharge blower 111. The pressure loss of the element 109 caused a decrease in the exhaust air volume.

The ventilation path switching damper 1.2 is closed, and indoor air is sucked into the indoor air ventilation path 16 from the first indoor suction lower. This sucked indoor air passes above the second ventilation passage switching damper 2 and above the first ventilation passage switching damper 1, flows out into the indoor air discharge ventilation passage 14, and is then moved by the indoor air discharge blower 9. The air is exhausted from the outdoor outlet 6.

の影響を受けずに排気風量を確保できる。As described above, according to this embodiment, the total heat exchange element 3 and the sensible heat exchange element 4 are arranged in series, and the outdoor air is constantly passed through each heat exchange element, and the indoor heat is exchanged by the outdoor air suction blower 1o. By discharging into the container 13, the ventilation air volume is the same in both total heat exchange ventilation and sensible heat exchange ventilation. Furthermore, when normally ventilated room air is exhausted, it does not pass through either the total heat exchange element 3 or the sensible heat exchange element 4, so the exhaust air volume can be secured without being affected by pressure loss.
発明の効果
以上の実施例の説明よシ明らかなように本発明によれば
、全熱交換換気、顕熱交換換気いずれの場合でも換気風
量は同じであるので室内の圧力と室外の圧力は同じとな

、風量の低下を招かないので送＠機の容量を大きくしな
くても排気風量が確保できることとなる。。Effects of the Invention As is clear from the explanation of the embodiments above, according to the present invention, the ventilation air volume is the same in both total heat exchange ventilation and sensible heat exchange ventilation, so the indoor pressure and outdoor pressure are the same. Tonaυ, the doors and windows will not be difficult to open or close, and drafts will not come in. Also, when exhausting indoor air using normal ventilation, the air volume does not decrease, so the exhaust air volume can be secured without increasing the capacity of the blower. .
