Abstract

A refrigeration system including a first evaporator having a capillary type expansion device controlling the flow of refrigerant thereto and a second evaporator having a thermal expansion valve for controlling the flow of refrigerant thereto. The system further includes a refrigerant compressor for discharging high pressure refrigerant vapor and a refrigerant condenser for receiving the high pressure refrigerant vapor and for converting the vaporous refrigerant to a relatively high pressure mixture of liquid and vaporous refrigerant. The system further includes a separator for receiving the relatively high pressure mixture from the condenser and for separating a substantial portion of the liquid refrigerant from the vapor liquid mixture. A first conduit is connected to the separator for delivering the separated liquid refrigerant to the thermal expansion valve and a second conduit is provided for delivering the remainder of the vapor liquid mixture to the capillary type expansion device.
