RISE OF ENERGY EFFICIENCY OF DOMESTIC REFRIGERATORS WITH COOLING SYSTEMS OF COMPRESSOR

Abstract

There the determination techniques for the main characteristics of tight compressors, for the energy efficiency of refrigerating assemblies and of domestic refrigerators have been developed for the performance of experimental studies. The test beds for the study of tight compressors and of refrigerating assemblies have been designed specially. The energy-caring method of cold production in the domestic refrigerators on the basis of boiling processes and of condensation processes of cooling agent, which are repeated cyclically, in several series-joined cooling systems of compressor has been developed and has been substantiated. The structural approaches of refrigerating assemblies and of tight compressors (the Inventor's Certificates number 640041, 951025, 1028878, 100693) have been developed. The application of pointed approaches allows to reduce the energy expenditure of refrigerators by 10-15%. The KhKV-6 tight compressor with the developed cooling system has been put into the operationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
