摘要:
A refrigerating system of a gas injection type having first and second stage pressure reducers 3 and 5, between which a separator 4 is arranged, and a conduit 10 for introduction of a gaseous refrigerant separated at a separator 4 into a compressor 1. A by-pass conduit 11 is connected to a refrigerating system so that the second stage pressure reducer 5 is by-passed. An ON-OFF control valve 12 is arranged in the by-pass conduit. The control valve 12 is switched to an opened condition during a low load of the air conditioning system, which makes a pressure difference low between the outlet of the separator 4 and an evaporator 6, which prevent gas injection from being executed. A control valve can also be arranged in a gas injection conduit 10, which controls an amount of the gas injection in accordance with a ratio (compression ratio) of an outlet pressure to an intake pressure in such a manner a reduction of a gas injection amount is obtained when a value of the compression ratio is lower than a predetermined value, thereby preventing over-compression from occurring.
