VEHICLE AIR CONDITIONER

Japanese Patent JP2016049915

A

PROBLEM TO BE SOLVED: To provide a vehicle air conditioner capable of quickly warming air-conditioning air even in the state of a large heating load without bringing about any difficulty such as the increase of noise.SOLUTION: The vehicle air conditioner includes an indoor condenser 55 for radiating the heat of a refrigerant compressed by a compressor 21 and an outdoor heat exchanger 24 for exchanging heat with outside air. Between a first pressure reduction valve 37 and a second pressure reduction valve 38 on the downstream side of the indoor condenser 55, a gas-liquid separator 39 is provided to separate the refrigerant of middle pressure into a gas refrigerant and a liquid refrigerant. The vehicle air conditioner further includes an injection passage 42 for introducing the gas refrigerant of the middle pressure into the compressor 21, and an outdoor heat exchanger side passage 43 for reducing the pressure of the gas refrigerant of the middle pressure by the second pressure reduction valve 38 and introducing it into the outdoor heat exchanger 24. The refrigerant heat-exchanged with the outdoor heat exchanger 24 and the gas refrigerant of the middle pressure are introduced into the compressor 21 to execute a heating operation. The second gas-liquid separator 39 includes heating means such as an electric heater 44 capable of raising a temperature in the inside thereof.SELECTED DRAWING: Figure 1
