冷房が出来ないという欠点がある。On the other hand, there is an air conditioning ventilation fan that uses a total heat exchanger as a ventilation fan to reduce ventilation loss, but it does not have a cooling/heating function. In addition, with conventional window-type heat pump air conditioners and air conditioning ventilation fans that do not have a non-heat exchange normal ventilation function, when the outside temperature drops below room temperature, such as during a summer night, energy-saving outside air cooling such as a wind fan can be used. The drawback is that it cannot be done.

Indoor air and outdoor air are sucked in by blowers 3 and 4 through intake ports 11 and 12, respectively, and after undergoing total heat exchange in both total heat exchangers 14, are mixed into outdoor circulating air and indoor circulating air, respectively. In this case, the ratio of the ventilation air volume to the total indoor air volume can be controlled by adjusting the degree of opening and closing of the shutters 19 and 20.

ーのロスの少ない全熱交換換気ができる。This is done with the arrows 19 and 20 closed. In this case, outdoor air is sucked by the blower 4 and the outdoor air intake port 13
The air is drawn into the room, passes through the outdoor air supply air passage 12, exchanges total heat with exhaust air from the room in the total heat exchanger 14, and then is supplied into the room. Similarly, exhaust air from the room is sucked in by the blower 3, passes through the indoor air intake port 11, the indoor air exhaust air passage 10, exchanges heat with the supply air from the outdoors in the total heat exchanger 14, and then goes outside. Exhausted. This 1/3 capacity (1/3 capacity) is exactly the same as that of a general air ventilation fan, and allows for total heat exchange ventilation with less loss of thermal energy.
なお、本実施例の場合の換気風量は２７７Ｉ殉１ｎで、
エンタルピーの交換効率は約６０％である。In addition, the ventilation air volume in the case of this example is 277I 1n,
The enthalpy exchange efficiency is about 60%.

の両循環ｊ虱路の短絡１コとなっている。FIG. 6 shows the airflow and the state of each part during simultaneous supply and exhaust ventilation (non-heat exchange ventilation). Stop compressor 9, open damper 15.16, 21. 22 is closed and the shutters 19 and 20 are opened, the indoor air that has entered the indoor air circulation duct 6 is sucked by the blower 3 to the outdoor side through the total heat exchanger 14, and then the outdoor air circulation duct is drawn. The outdoor air that has entered 5 is sucked indoors by the blower 41/c through the total heat exchanger 14, thereby performing simultaneous supply and exhaust ventilation. ' In this case, the total heat exchanger 14 only serves as a passage for the air flow, and this solid air flow does not exchange heat within the total heat exchanger 14 . In the figure, 25 is an opening on the outdoor air circulation duct 5 side of the outdoor air supply duct 120, 26 is an opening on the indoor air circulation duct 6 side, and 27 is an opening of the indoor air exhaust duct 10. The opening part on the side of the circulation air passage 6, 28 (is the opening on the side of the outdoor air circulation passage 5, but in this case,
There is one short circuit between both circulation channels.
−カ、ダンパー１５および１６ば、この場合風路の開閉

制御板として重要な働きもしている。- In this case, the dampers 15 and 16 play an important role not only in opening and closing the air passage, but also as a control board that changes the airflow suction direction of the blowers 3 and 4.
以上のような換気機能は、一般の同時給排の換気扇やウ
ィンドファンの場合と同じである。なお、本実施例の場
合の換気風量は約３７ｎ３／ｍ ｉｎである。The ventilation function described above is the same as that of a general simultaneous supply/exhaust ventilation fan or window fan. Note that the ventilation air volume in this example is approximately 37 n3/min.

使用できる。Effects of the Invention (f) Compared to conventional air conditioners, the wind type heat pump air conditioner of the present invention can perform partial total heat exchange ventilation even during cooling/heating operation, making it possible to operate a cold/heated store for a long time in a closed room. Furthermore, ventilation loss can be minimized1.In addition to being used as a refrigerating air conditioner, it can also be used as an air conditioning ventilation fan, simultaneous supply/exhaust ventilation fan, window fan, etc., so it can be used for energy-saving ventilation, general ventilation, etc. It can be used all year round as it can also be used as a fresh air filter.
