Abstract
A heat pump deviceis operated so as to make a switch between multiple operation modes including a first dehumidification and heating operation mode in which a refrigerant discharged from a compressor is circulated through a downstream interior heat exchanger, a first pressure reducing valve, an upstream interior heat exchanger, and an exterior heat exchangerin this order so that the heat exchangerfunctions as a radiator and the heat exchangerfunctions as a heat absorber, and a second dehumidification and heating operation mode in which the refrigerant discharged from the compressor is circulated through the downstream interior heat exchanger, a second pressure reducing valve, the exterior heat exchanger, and the upstream interior heat exchangerin this order so that the heat exchangerfunctions as a radiator and the heat exchangerfunctions as a heat absorber.
