In this invention, when attempting to locally air condition a room separately from the main air conditioner, when exhausting excess indoor air, an exhaust heat exchanger is used to recover the heat in the exhaust air and transfer it to the indoor air. When the air is taken in and resupplied indoors, it is fed to the supply air heat exchanger. In addition, by configuring a heat pump with heat exchangers for exhaust air and air supply, and a single compressor, air conditioning is performed according to the seasons of summer and winter.

も不要となる。 Therefore, the heat possessed by the surplus air can be effectively used, and for example, by using 400m 3 /hr of surplus air, it is possible to obtain an output of approximately 1800Kcal/hr. Furthermore, inside the device, it is sufficient to connect the exhaust duct to the existing exhaust duct, and the construction cost is extremely low compared to the conventional fan coil unit system, which requires cold and hot water piping. The drain from the heat exchanger is either sprayed into the exhaust system and released into the atmosphere along with the exhaust gas, or sprayed into the indoor air system to humidify indoor return air, so drain piping is not required.
