VEHICULAR HEAT PUMP CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/101062
Kind Code:
A1
Abstract:
The present invention both suppresses noise from a compressor and ensures a required heating capacity. The present invention comprises: a compressor (11) that suctions, compresses, and discharges a refrigerant; a heating unit (13, 131) that heats an object to be heated, by using the refrigerant discharged from the compressor (11) as the heat source; a pressure reduction unit (14c) that reduces the pressure of the refrigerant which has flowed out from the heating unit (13, 131); and a heat absorption unit (20) that causes the refrigerant which has been reduced in pressure by the pressure reduction unit (14c) to absorb heat generated by a heat generating unit (70), wherein, in the heat absorption unit (20), the heat absorption amount is increased as the noise level allowed for the compressor (11) decreases.
