Abstract: A system for operating a refrigeration system, may include a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: operating a main refrigeration circuit as a function of a cooling load of an evaporation stage of a first facility; reclaiming heat from the main refrigeration circuit to provide heat to at least a second facility separate from the first facility in response to at least two concurrent heat demands for at least the second facility; and storing cold heat or hot heat as a function of a difference between the heat reclaimed and the cooling load. A thermal hub operated by such a system may also be provided.

Abstract: A refrigeration system may have a main refrigeration circuit including at least a first compression stage, a first refrigerant cooling stage, and an evaporation stage, a refrigerant circulating between the first compression stage, the first refrigerant cooling stage and the evaporation stage in a refrigeration cycle. A heat pump compression system may be in fluid communication with the main refrigeration circuit, the heat pump compression system including a second compression stage and a second refrigerant cooling stage in which said refrigerant circulates. A controller unit may be configured for operating the refrigeration system such that the heat pump compression system has a reclaim mode in which heat is reclaimed in the second cooling stage at a higher temperature than in the first cooling stage, and a cooling mode in which the first compression stage and the second compression stage operate concurrently to meet a cooling load of the evaporation stage.

Abstract: A refrigeration system has a main refrigeration circuit including a compression stage, a condensing stage, and an evaporation stage, a refrigerant circulating between the compression stage, the condensing stage and the evaporation stage in a refrigeration cycle. An integrated transfer system is in closeable and openable fluid communication with the main refrigeration circuit, the transfer system including a receiver. Valves are operable to selectively open the fluid communication between the main refrigeration circuit and the transfer system. A motive force source displaces refrigerant from the main refrigeration circuit to the transfer system.
