Document Type and Number:
WIPO Patent Application WO/2019/119678
Kind Code:
A1
Abstract:
A CO2 refrigerant-based transcritical cycle rail vehicle air conditioning system, wherein a refrigeration cycle loop comprises an intermediate heat exchanger (05); a high-temperature medium inlet (051) of the intermediate heat exchanger (05) is connected to a medium outlet of a gas cooler (021); a high-temperature medium outlet (052) of the intermediate heat exchanger (05) is connected to a medium inlet of a throttling expansion device (03); a low-temperature medium inlet (053) of the intermediate heat exchanger (05) is connected to a medium outlet of an evaporator (041); a low-temperature medium outlet (054) of the intermediate heat exchanger (05) is connected to a medium inlet of a compressor (01); a refrigerant in the refrigeration cycle loop is CO2; the refrigeration cycle is a transcritical cycle; the compressor (01) is a transcritical refrigeration compressor. The system not only can meet strict environmental protection requirements, but also can guarantee refrigeration efficiency and meet light weight requirements for rail vehicles.
