Refrigeration system and a separator therefor

摘要

A refrigeration system comprises a compressor, a condenser, a receiver and an evaporator, each having an inlet and an outlet, and a separator having an inlet and a first and second outlet, connected to each other conventionally. The separator is positioned laterally of the evaporator and closer thereto than to the compressor. A controller ensures overfeed of the evaporator by regulating the feed rate of liquid refrigerant from the receiver such that the separator is feeding the evaporator with liquid refrigerant in proportion to demand and safeguarding the desired overfeed. The separator comprises a cylindrical container having two outlets and an inlet for separating the vapor and liquid components of a refrigerant. The inlet is directed tangentially into the cylindrical container. A foraminous partition is positioned inside the container and extends downwardly of the inlet and inwardly of the inner surface of the container for delimiting the central space and the peripheral space of the container from each other.
