Carbon dioxide refrigeration system has separator with integral heat exchanger; carbon dioxide can be evaporated in heat exchanger by expansion valve, liquefied by compressor circuit

摘要

The system has a compressor circuit (1) and an evaporator circuit (2) coupled together by a separator (3) with an integral heat exchanger (4). Carbon dioxide can be evaporated in the heat exchanger, which is arranged inside the separator, by an expansion valve (6) and can be liquefied again by a compressor circuit.
