Development and implementation of absorption lithium bromide refrigeration machines and heat pumps

For more than 40 years, absorption lithium bromide refrigerating machines have been successfully used in world practice to produce chilled water (7 °C). In our country, the introduction of machines of this type was initiated by the work of the Department of Refrigeration Machines of the Leningrad Technological Institute of the Refrigeration Industry (now St. Petersburg State University of Low-Temperature and Food Technologies), where, under the guidance of prof. L.M. Rozenfeld designed a pilot sample of an absorption lithium bromide refrigerating machine with a design capacity of 3 MW. Tests of this sample as a refrigeration machine and heat pump, carried out by LTIHP and VNIIkholodmash in 1964-1966. at the industrial stand of the Chernihiv artificial fiber plant in a wide range of temperatures of heat sources and operating modes laid the foundation for the production of machines of this type in our country.
