摘要： 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.

摘要： A cascade CO2 refrigeration system includes a medium temperature loop for circulating a medium refrigerant and a low temperature loop for circulating a CO2 refrigerant. The medium temperature loop includes a heat exchanger having a first side and a second side. The first side evaporates the medium temperature refrigerant. The low temperature loop includes a discharge header for circulating the CO2 refrigerant through the second side of the heat exchanger to condense the CO2 refrigerant, a liquid-vapor separator collects liquid CO2 refrigerant and directs vapor CO2 refrigerant to the second side of the heat exchanger. A liquid CO2 supply header receives liquid CO2 refrigerant from the liquid-vapor separator. Medium temperature loads receive liquid CO2 refrigerant from the liquid supply header for use as a liquid coolant at a medium temperature. An expansion device expands liquid CO2 refrigerant from the liquid supply header into a low temperature liquid-vapor mixture for use by the low temperature loads.

摘要： A refrigeration system includes a refrigeration subsystem and a coolant subsystem. The refrigeration subsystem is configured to circulate a refrigerant between an evaporator (12,22) within which a refrigerant absorbs heat and a gas cooler/condenser (2) within which the refrigerant rejects heat to provide cooling to a temperature-controlled space. The coolant subsystem includes a heat exchanger (61) coupled to the refrigeration subsystem at an outlet of the gas cooler/condenser and configured to transfer heat from the refrigerant exiting the gas cooler/condenser to an external coolant when the external coolant flows through the heat exchanger, a control valve (64), and a controller (50) configured to operate the control valve to control a flow of at least one of the refrigerant or the external coolant through the heat exchanger based on a temperature of the external coolant relative to a temperature of the refrigerant exiting the gas cooler/condenser.

摘要： A refrigeration system with pressure-balanced heat reclaim includes at least one compressor configured to discharge a compressed refrigerant. A heat reclaim branch has a first end configured to receive at least a first portion of the compressed refrigerant and a second end, the heat reclaim branch also has a first refrigerant pressure drop. A condensing branch has a first end configured to receive at least a second portion of the compressed refrigerant and a second end, the second end of the condensing branch is fluidly coupled to the second end of the heat reclaim branch, and the condensing branch has a second refrigerant pressure drop. A pressure regulation device is disposed on one of the heat reclaim branch and the condensing branch and substantially equalizes the first refrigerant pressure drop and the second refrigerant pressure drop.
