Abstract

See full text

A control device of a vehicle air-conditioning apparatus, in a heating operation by use of a heating unit, has at least a temperature control target heat absorption heating mode in which a refrigerant that has been discharged from a compressor and has dissipated heat in the heating unit absorbs heat in a temperature control target-specific heat exchanger, and a combined heating mode in which the refrigerant that has been discharged from the compressor and has dissipated heat in the heating unit absorbs heat in an outdoor heat exchanger and the temperature control target-specific heat exchanger, and during the heating operation in the combined heating mode, performs control in such a manner as to determine an operating state that allows the refrigerant to accumulate in the outdoor heat exchanger, and switch to the temperature control target heat absorption heating mode to execute the heating operation.
