Patent number: 11852391Abstract: Systems and methods for controlling pressure in a CO2 refrigeration system are provided. The pressure control system includes a pressure sensor, a gas bypass valve, a parallel compressor, and a controller. The pressure sensor is configured to measure a pressure within a receiving tank of the CO2 refrigeration system. The gas bypass valve is fluidly connected with an outlet of the receiving tank and arranged in series with a compressor of the CO2 refrigeration system. The parallel compressor is fluidly connected with the outlet of the receiving tank and arranged in parallel with both the gas bypass valve and the compressor of the CO2 refrigeration system. The controller is configured to receive a pressure measurement from the pressure sensor and operate both the gas bypass valve and the parallel compressor, in response to the pressure measurement, to control the pressure within the receiving tank.Type: GrantFiled: June 7, 2021Date of Patent: December 26, 2023Assignee: Hill Phoenix, Inc.Inventors: Kim G. Christensen, Jeffrey Newel, John D. Bittner

Patent number: 9709302Abstract: A refrigeration system for use with refrigerated LT and MT display cases in facilities such as supermarkets, has an absorption chiller that uses waste heat from a nearby source to provide cooling to the refrigeration system to take advantage of the synergy and improve overall efficiency of the refrigeration system. The cooling provided by the absorption chiller may be in the form of a coolant (e.g. water, glycol, water-glycol mixture, etc.) that circulates between the chiller and one or more of a pre-cooler, sub-cooler or condenser in the refrigeration system in a manner that uses waste heat from a nearby source to reduce the need for installed condensing capacity in the refrigeration system and improve thermal efficiency and obtain cost savings.Type: GrantFiled: December 19, 2013Date of Patent: July 18, 2017Inventors: J. Scott Martin, Shitong Zha, Jeffrey Newel, Timothy E. Lukes, Willis L. McCullough
