  • Refrigeration system and method of refrigeration load control
    Patent number: 11268744
    Abstract: A method of controlling a refrigeration system including a medium temperature refrigeration load and a low temperature refrigeration load. The method includes selectively bypassing refrigerant between a medium temperature suction group and a low temperature suction group via a bypass line using an electronic valve positioned in the bypass line. The method also includes controlling flow of refrigerant between the medium temperature suction group and the low temperature suction group via a controller communicatively coupled to the valve, and modulating the valve at any position between a closed position and a full open position to vary an amount of refrigerant flow between the medium temperature suction group and the low temperature suction group in response to determining, via the controller, one or both of a state of the medium temperature suction group and a state of the low temperature suction group.
    Type: Grant

  • Modular refrigeration assembly
    Patent number: 9677796
    Abstract: A subassembly of a refrigeration system includes a frame having a plurality of support members and one or more cross members, each cross member extending between two of the support members. A heat exchanger is operable to condense refrigerant. A compressor is supported by the frame and operable to provide refrigerant to the heat exchanger. A portion of the frame is configured to receive and contain refrigerant condensed by the heat exchanger.
