Kind Code:
B2
Abstract:
A refrigeration system is disclosed which incorporates apparatus for preventing overheating of the compressor (10, 10') by selectively feeding liquid refrigerant from the outlet of the condenser (16, 16') to the compressor (10, 10'). In one embodiment the refrigerant fluid from the condenser (16) is injected into the suction manifold (52) of the compressor (10). In another embodiment this fluid is injected directly into the compression chamber or chambers (88, 90). Control means are provided which include a temperature sensor (32, 70, 112) located within the compressor discharge chamber (58, 114) and valve means (38, 100, 102) responsive thereto to control the flow of liquid refrigerant to the suction manifold (52) or compression chamber (88, 90).
