A TRANSCRITICAL REFRIGERATION SYSTEM WITH A BOOSTER

摘要

Transcritical refrigeration system (10) with a booster and a bypass valve, the system comprising a flow circuit and a high pressure compressor (20), the compressor output being connected to an input of a gas cooler (24) and having an output connected with an input of a high temperature pressure reducing device (27), and having an output connected to a receiver (26) with a liquid output connected to an input of a medium temperature expansion valve (28) with an output connected to an input of a medium temperature evaporator (30) and having an output connected with the input of the high pressure compressor (20), and a gas bypass valve (32) with an input connected to a gas output of the receiver (26) and an output connected with the output of the medium temperature evaporator (30), the gas bypass valve (32) lowering the pressure in tubing between the output of the high temperature expansion valve (27) and the input of the medium and low temperature expansion valves (28).
