Title:
VEHICLE HEAT PUMP DEVICE, AND VEHICLE AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/087645
Kind Code:
A1
Abstract:
Provided are a vehicle heat pump device and a vehicle air-conditioning device such that, compared with a conventional vehicle air-conditioning device that uses a heat pump cycle only during cooling operation, heating operation can be performed by using a heat pump cycle with only a small number of modifications in a refrigerant piping pattern. The vehicle heat pump device is a vehicle heat pump device that uses a high temperature, high pressure refrigerant that is discharged from a compressor outside a housing and then guided in. The heat pump device is provided with: a first refrigerant guide-in unit that guides in the high temperature, high pressure refrigerant discharged by the compressor from outside the housing; a water refrigerant heat exchanger that can dissipate heat from the high temperature, high pressure refrigerant guided in from the first refrigerant guide-in unit into a cooling fluid; and a housing accommodating the water refrigerant heat exchanger. The heat pump device is further provided with a cooling fluid guide-in unit that can guide the cooling fluid from outside the housing into the water refrigerant heat exchanger, a cooling fluid guide-out unit that can guide the cooling fluid out of the water refrigerant heat exchanger to the outside of the housing, and a first refrigerant guide-out unit that guides the refrigerant that has passed through the water refrigerant heat exchanger to the outside of the housing.
