R22/R404A/R290: differences between these three refrigerants from the point of view of compressor.

Oggetto: R22/R404A/R290: differenze dei tre refrigeranti dal punto di vista del compressore.

Summary

Tests were implemented on semi-hermetic compressors of various refrigerating capacities; these tests were carried out in accordance with the German DIN 80 standard, in the ILK Institute Dresden. The article reviews the test results: refrigerating capacity, power imput, COP, end-of-compression temperature, compression ratio. The authors recommend the use of polyolester.
