Abstract

Abstract: As a natural medium, R290 has become the trend choice in the refrigerant substitution process because of its excellent thermodynamic performance. Through the performance test of R290 compressor under different standard test conditions, it can be seen that the change of test conditions has obvious influence on the difference of compressor refrigeration capacity and COP. The performance distribution characteristics of 40 R290 compressors under the national standard were studied. Compared with R600a compressors, R290 compressor is also excellent in performance grade in performance grade.

Key words: Compressor, Refrigerant, R290, Cooling capacity
