Patent number: 11940186Abstract: A refrigeration system includes a refrigeration circuit and a coolant circuit separate from the refrigeration circuit. The refrigerant circuit includes a gas cooler/condenser, a receiver, and an evaporator. The coolant circuit includes a heat exchanger configured to transfer heat from a refrigerant circulating within the refrigeration circuit into a coolant circulating within the coolant circuit, a heat sink configured to remove heat from the coolant circulating within the coolant circuit, and a magnetocaloric conditioning unit configured to transfer heat from the coolant within a first fluid conduit of the coolant circuit into the coolant within a second fluid conduit of the coolant circuit. The first fluid conduit connects an outlet of the heat exchanger to an inlet of the heat sink, whereas the second fluid conduit connects an outlet of the heat sink to an inlet of the heat exchanger.Type: GrantFiled: July 25, 2022Date of Patent: March 26, 2024Assignee: Hill Phoenix, Inc.Inventors: Jeffrey E. Newel, John D. Bittner, Niel M. Hayes

Publication number: 20230358445Abstract: A cooling system includes a distribution system and a cooling unit. The distribution system is configured to circulate a distribution system refrigerant. The distribution system includes a distribution system pump, a main cooler, a distribution system input conduit, and a distribution system output conduit. The main cooler is configured to receive the distribution system refrigerant from the distribution system pump. The distribution system input conduit is configured to receive the distribution system refrigerant from the main cooler. The distribution system output conduit is configured to receive the distribution system refrigerant from the distribution system input conduit and to provide the distribution system refrigerant to the distribution system pump. The cooling unit is configured to circulate a cooling unit refrigerant. The cooling unit includes a cooling unit pump, an upstream receiver, a condenser, a downstream receiver, and an evaporator.Type: ApplicationFiled: July 20, 2023Publication date: November 9, 2023Inventors: Jeffrey E. Newel, Neil John Rathje, Timothy Dean Swofford

Patent number: 11674719Abstract: A refrigeration system includes a receiver, a gas bypass valve, a parallel compressor, and a controller. The gas bypass valve and the parallel compressor are fluidly coupled to an outlet of the receiver in parallel and configured to control a pressure of a gas refrigerant in the receiver. The controller is configured to switch from operating the gas bypass valve to operating the parallel compressor to control the pressure of the gas refrigerant in the receiver in response to a value of a process variable crossing a switchover setpoint. The value of the process variable depends on an amount of the gas refrigerant produced by the refrigeration system. The controller is configured to automatically adjust the switchover setpoint in response to the amount of the gas refrigerant produced by the refrigeration system being insufficient to sustain operation of the parallel compressor.Type: GrantFiled: September 1, 2021Date of Patent: June 13, 2023Assignee: Hill Phoenix, Inc.Inventors: Niel M.

Publication number: 20230076487Abstract: A refrigeration assembly includes a receiver tank, a heat exchanger, a first piping assembly, and a second piping assembly. The receiver tank has a fluid outlet and a fluid inlet that receives a working fluid. The heat exchanger is disposed within the receiver tank. The heat exchanger has coiled tubing that is fluidly coupled to the fluid inlet and to the fluid outlet. The first piping assembly is disposed between and is fluidly coupled to the fluid inlet and the coiled tubing. The first piping assembly has a first double riser and a first P-trap. The second piping assembly is disposed between and is fluidly coupled to the fluid outlet and the coiled tubing. The second piping assembly includes a second double riser and a second P-trap.Type: ApplicationFiled: September 7, 2021Publication date: March 9, 2023Inventors: Senthilkumar Kandappa Goundar Shanmugam, Jeffrey E.
