VEHICLE HEAT PUMP DEVICE, AND VEHICLE AIR-CONDITIONING DEVICE

摘要

A 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.

主权项

1. A vehicle heat pump apparatus that introduces and uses a high-temperature and high-pressure refrigerant discharged from a compressor configured to compress a suctioned refrigerant disposed outside a housing, the apparatus comprising:
a first refrigerant introduction section through which the high-temperature and high-pressure refrigerant discharged from the compressor is introduced from outside the housing; a cooling water-to-refrigerant heat exchanger capable of releasing heat from the high-temperature and high-pressure refrigerant introduced from the first refrigerant introduction section to a cooling water; the housing that accommodates the cooling water-to-refrigerant heat exchanger; a cooling water introduction section that allows the cooling water to be introduced into the cooling water-to-refrigerant heat exchanger from outside the housing; a cooling water outlet section that allows the cooling water to flow through outside the housing from the cooling water-to-refrigerant heat exchanger; and a first refrigerant outlet section that allows the refrigerant passing through the cooling water-to-refrigerant heat exchanger to flows through outside the housing.
