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 area 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.

Abstract: A decentralized condenser evaporator system includes (i) a condenser system positioned to receive a gaseous refrigerant from a centralized compressor system and configured to condense the gaseous refrigerant into a liquid refrigerant, (ii) a controlled pressure receiver 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 controlled pressure receiver. The expansion device is positioned between the controlled pressure receiver and the conduit, and configured to facilitate modulating an amount of the liquid refrigerant that flows into the conduit from the controlled pressure receiver. The fan is positioned to facilitate providing a cooling operation to an area 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 to maintain a desired level of the liquid refrigerant within the controlled pressure receiver and facilitate maintaining a system condensing pressure of the refrigeration system at a target system condensing pressure.

Abstract: A decentralized condenser evaporator system includes a condenser system, a controlled pressure receiver, a subcooler system, and an evaporator system. The condenser system is positioned to receive a compressed gaseous refrigerant from a centralized compressor system. The condenser system is configured to condense the compressed gaseous refrigerant into a liquid refrigerant. The controlled pressure receiver is positioned to receive and store the liquid refrigerant. The subcooler system is positioned to receive the liquid refrigerant from the controlled pressure receiver. The subcooler system is configured to sub-cool the liquid refrigerant into a sub-cooled liquid refrigerant. The evaporator system is positioned to receive the sub-cooled liquid refrigerant from the subcooler system. The evaporator system is configured to facilitate providing a cooling operation to a cooling zone through evaporation of the sub-cooled liquid refrigerant flowing through the evaporator system into an evaporated gaseous refrigerant which is returned to the centralized compressor system.

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.
