Document Type and Number:
Japanese Patent JP7233953
Kind Code:
B2
Abstract:
[Problem] To provide a vehicle air conditioner capable of achieving a target blow temperature while preventing freezing of a heat absorber. [Solution] A vehicle air conditioner is provided with: 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, and a control device executes a dehumidification heating mode in which a refrigerant discharged from the compressor 2 is radiated by the radiator 4, the radiated refrigerant is slit into streams, the pressure of one stream is reduced by the indoor expansion valve 8 and subsequently heat is absorbed by the heat absorber 9, and the pressure of the other stream is reduced by the outdoor expansion valve 6 and subsequently heat is absorbed by the outdoor heat exchanger 7. The control device fully closes the indoor expansion valve 8 when the temperature of the heat absorber 9 is lower than a predetermined value.
