VENTILATING AND AIR CONDITIONING DEVICE

摘要

A ventilating and air conditioning device having a circulation fan for drawing air from a first inlet opened in a first living space and ejecting the air from a first outlet opening in the first living space, a ventilation fan for drawing air from a second inlet opened in a second living space and ejecting the air to the outdoors or the first living space, a compressor, a first heat exchanger for exchanging heat between air sent by the circulation fan and refrigerant, an expansion mechanism, a second heat exchanger for exchanging heat between air sent by the ventilation fan and the refrigerant, and a refrigerant circuit laid so that the refrigerant flows through the compressor, the first heat exchanger, the expansion mechanism, and the second heat exchanger, in that order. The ventilating and air conditioning device further has a path changeover mechanism for controlling the amount of the air subjected to the heat exchange by the second heat exchanger and ejected to the outdoors and the first living space.
