Abstract: A refrigeration subsystem removably received within a base machine to cool an object. The subsystem includes a body with an opening that receives the object. An evaporator thermally communicates with the object, which is cooled by refrigerant flowing through the evaporator. A compressor receives the refrigerant downstream of the evaporator and increases a refrigerant pressure. A condenser receives the refrigerant downstream of the compressor, which cools the refrigerant. An expansion device receives the refrigerant downstream of the condenser and decreases its pressure, the evaporator being downstream from the expansion device. A refrigerant circuit fluidly couples the evaporator, compressor, condenser, and expansion device such that the refrigerant flows therebetween, all of which are coupled to the body and move together therewith. The refrigerant circuit forms a closed loop that remains unbroken when the body of the refrigerant subsystem is removed from the base machine.

Abstract: 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.
