Refrigerant circuit integrated air conditioner for cooling passenger cabin of hybrid vehicle, has expansion device with thermal energy exchanging cooling device on high pressure side of circuit for additional cooling of refrigerant

摘要

The air conditioner (10) has a heat exchanger formed as an evaporator (22) and a condenser (14), a compressor device (12), and an expansion device (18) that are fluidly connected with each other for circulating a refrigerant. The expansion device is provided with a thermal energy exchanging cooling device (20) on a high pressure side of a refrigerant circuit for additional cooling of the refrigerant. The cooling device is arranged downstream of the condenser in the refrigerant circuit.
