1. A vehicle air conditioner comprising:
a heat pump device including
a compressor configured to compress refrigerant,first and second indoor heat exchangers arranged in a vehicle compartment, andan outdoor heat exchanger disposed outside the vehicle compartment; an indoor air conditioning unit
housing the first and second indoor heat exchangers,including an air blower configured to send air-conditioning air to the first and second indoor heat exchangers, andconfigured to generate air-conditioned air to supply the air-conditioned air into the vehicle compartment; a flow path switching device
including a refrigerant inlet into which refrigerant flows from the first indoor heat exchanger, a normal air-heating refrigerant outlet connected to the second indoor heat exchanger such that the refrigerant flowing into the refrigerant inlet flows into the second indoor heat exchanger, and an air-heating start-up refrigerant outlet causing the refrigerant flowing into the refrigerant inlet to bypass the second indoor heat exchanger, andconfigured to switch between a normal air-heating mode in which the refrigerant flowing into the refrigerant inlet flows into the normal air-heating refrigerant outlet and an air-heating start-up mode in which the refrigerant flowing into the refrigerant inlet flows into the air-heating start-up refrigerant outlet; and an air conditioning control device configured to control the flow path switching device, wherein the air conditioning control device is configured to cause the flow path switching device to be in the air-heating start-up mode at beginning of air-heating and then to be in the normal air-heating mode, and in the air-heating start-up mode, the outdoor heat exchanger serves as a heat absorber. |
