SYSTEMS AND METHODS FOR PREVENTING OVERHEATING IN REFRIGERATION SYSTEMS

A refrigeration system for cooling an object and preventing system overheating. The system includes an evaporator coil configured to thermally communicate with the object, where the object is cooled by a refrigerant flowing through the evaporator coil. A compressor receives the refrigerant downstream from the evaporator coil and increases a pressure of the refrigerant. A condenser receives the refrigerant downstream from the compressor, where the refrigerant is cooled by flowing through the condenser. An expansion valve receives the refrigerant downstream from the condenser and decreases the pressure of the refrigerant, where the evaporator coil receives the refrigerant downstream from the expansion valve. An bypass coolant valve also receives the refrigerant downstream from the condenser. The compressor also receives the refrigerant downstream from the bypass coolant valve, and the refrigerant received by the compressor from the bypass coolant valve bypasses the evaporator coil to prevent overheating of the compressor.
