Abstract

Abstract: By comparing the advantages and disadvantages of R290 with R134a and R404A refrigerants, it is analyzed that R290 refrigerant is the most promising environmentally friendly refrigerant. This paper analyzes the causes of failures such as compressor start-up and stuck in R290 refrigeration compressors, proposes targeted solutions, and carries out prototype research and development. The results show that the application of these technical measures has a good influence effect. The reliability of the compressor is greatly improved.

Key words: R290, Compressor, Reliability, Improvement, Crankshaft
