Abstract
A heater core is connected with an engine to receive a hot engine-coolant, which operates as a main heater. An evaporator in a refrigerating cycle operates as an auxiliary heater. A condenser is connected to an outlet of the compressor, and the evaporator is connected to an inlet of the compressor. A bypass conduit is provided, one end of which is connected to the outlet side of the compressor and another end of which is connected to an inlet side of the evaporator. A expansion valve is disposed in the bypass conduit. In heating stage, the compressed hot refrigerant discharged from the compressor flows into the bypass conduit. The refrigerant is expanded by the expansion valve and radiates the heat in the evaporator.
