である。 In the above configuration, cooling and heating are performed between the outdoor unit 30 and the indoor unit 38 using a normal heat pump type refrigeration cycle. On the air conditioning ventilation fan 41 side, an exhaust fan 44 of the ventilation blower 43
The exhaust flow path and intake fan 45 shown by arrow C
As a result, an intake flow path shown by arrow D is formed, and the indoor air conditioned air to be exhausted in the total heat exchanger 42 and the air taken in from outside are heat exchanged, and at this time, the amount of heat of the indoor air to be exhausted is reduced. Collect. This recovery rate is about 70%, so when cooling, outside air whose temperature is higher than the indoor air temperature during cooling flows in.
During heating, outside air with a lower temperature flows in due to the indoor air temperature during heating, so the auxiliary heat exchanger 46 cools it during cooling and heats it during heating.
4, air with a temperature almost close to room temperature is blown out. That is, like the indoor heat exchanger 39, the auxiliary heat exchanger 46 acts as an evaporator during cooling and as a condenser during heating, so when the air flows from the auxiliary heat exchanger 46 toward the indoor air intake port 54, it acts as an air conditioner. The inside is cooled, while the heating is heated and blown out.

る。Effects of the Invention As is clear from the description of the above embodiments, the present invention provides an auxiliary heat exchanger in a heat pump type refrigeration cycle on the air conditioning ventilation fan side, and provides this on the lee side of the intake flow path of the total heat exchanger. The heat is recovered when outside air is taken in, and the air is further cooled (when cooling) or heated (heated) before being taken into the room, making up for the amount of heat that cannot be recovered by the total heat exchanger and returning it to the room. It is possible to eliminate changes in indoor temperature by blowing air out, and therefore there is no load fluctuation on the air conditioner side, reducing running costs and resulting in economical and energy-saving operation.
