摘要:
When a heating mode is set in a refrigerant cycle system, air is heated in a condenser (12) by condensing high-pressure gas refrigerant, a part of high-pressure refrigerant from the condenser is decompressed in a pressure reducing unit (26) to a middle pressure, and the other part of high-pressure refrigerant from the condenser is heat-exchanged with the middle-pressure refrigerant having passed through the pressure reducing unit in a refrigerant-refrigerant heat exchanger (23). Therefore, middle-pressure refrigerant having passed through the pressure reducing unit is evaporated in the refrigerant-refrigerant heat exchanger and the evaporated middle-pressure refrigerant is introduced into a gas injection port of a compressor (22). Thus, in the refrigerant cycle system, heating capacity can be improved due to the gas refrigerant injection into the compressor.

An air conditioning device for vehicle includes a first water-refrigerant heat exchanger, a second water-refrigerant heat exchanger, a first bypass passage, and a second bypass passage. The first bypass passage branches at a point of a coolant passage from a cooling portion of a heating component in the vehicle to the second water-refrigerant heat exchanger, and the first bypass passage is capable of being communicated with the coolant passage at an upstream side of the first water-refrigerant heat exchanger. The second bypass passage branches at a point of the coolant passage from a heater core to the first water-refrigerant heat exchanger, and the second bypass passage is capable of being communicated with the coolant passage at a downstream side of the first water-refrigerant heat exchanger. A part of the first bypass passage which includes a downstream end and a part of the second bypass passage which includes an upstream end are shared.
