Selectively controllable condenser and evaporator system

Abstract

A condenser and evaporator system includes (i) a condenser system positioned to receive a gaseous refrigerant from a compressor system and configured to condense the gaseous refrigerant into a liquid refrigerant, (ii) a controlled pressure receiver (CPR) positioned to receive and store the liquid refrigerant, (iii) an evaporator system including a conduit, an expansion valve, and a fan, and (iv) a controller. The conduit is positioned to receive the liquid refrigerant from the CPR. The expansion valve is positioned between the CPR and the conduit, and configured to facilitate modulating an amount of the liquid refrigerant that flows into the conduit from the CPR. The fan is positioned to facilitate providing a cooling operation to an arca associated with the evaporator system through evaporation of the liquid refrigerant flowing through the conduit. The controller is configured to control a stage of the condenser system and/or the evaporator system a condenser system, a reservoir, a compressor return conduit, an evaporator system, and a return line. The condenser system is configured to receive a compressed gaseous refrigerant from a compressor system and condense the compressed gaseous refrigerant into a liquid refrigerant. The reservoir is configured to receive the liquid refrigerant. The compressor return conduit is configured to couple the reservoir to the compressor system to direct gaseous refrigerant within the reservoir to the compressor system. The evaporator system is configured to receive the liquid refrigerant from the reservoir and perform a cooling operation where the liquid refrigerant is converted into an evaporated gaseous refrigerant to facilitate thermally regulating a cooling zone associated with the evaporator system. The return line is configured to couple the evaporator system to the reservoir and direct defrost condensate refrigerant to the reservoir from the evaporator system.
