Title:
VEHICULAR AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2020131846
Kind Code:
A
Abstract:
To provide a vehicular air conditioner capable of attaining a target blowout temperature while preventing freezing of a heat absorber.SOLUTION: A vehicular air conditioner includes a compressor 2, a radiator 4, an outdoor expansion valve 6, an outdoor heat exchanger 7, an indoor expansion valve 8 and a heat absorber 9. A control device executes a dehumidification heating mode of causing the radiator 4 to radiate heat from a refrigerant discharged from the compressor 2, dividing a flow of the refrigerant from which heat has been radiated, causing the heat absorber 9 to absorb heat from one of the divided refrigerant flows after decompressing it by using the indoor expansion valve 8 and causing the outdoor heat exchanger 7 to absorb heat from the other after decompressing it by using the outdoor expansion valve 6. When a temperature of the heat absorber 9 becomes lower than a predetermined value, the control device fully closes the indoor expansion valve 8.SELECTED DRAWING: Figure 1
