Abstract

When the operation mode of a heat pump device (20) is a first heating operation mode that uses two in-cabin heat exchangers (31, 32), in the case that a cabin exterior heat exchanger (33) has been detected to have frost, a second heating operation mode that uses one in-cabin heat exchanger (31) is switched to, and then a defrosting operation mode is switched to.

Description

technical field [0001] The present invention relates to a vehicle air conditioner mounted on a vehicle, and more particularly to a vehicle air conditioner including a heat pump device. Background technique [0002] Conventionally, waste heat of an internal combustion engine has been used as a heating heat source of an air conditioner for a vehicle. In recent years, however, electric vehicles not equipped with an internal combustion engine, plug-in hybrid vehicles equipped with an internal combustion engine but whose operation time is short, and the like have become popular. Therefore, how to achieve comfortable air conditioning on these vehicles becomes a problem. [0003] Patent Document 1 discloses a heat pump device including an electric compressor as a vehicle air conditioner. In addition to the electric compressor, this heat pump device is equipped with an exterior heat exchanger installed outside the cabin, an expansion valve, an upstream interior heat exchanger, and...
