Abstract

The energetic-ecological aspects of using of traditional refrigerants (R717, R22) and alternative refrigerants (R404C, R410A, R410B) in big gross capacity compressor aggregate are considered in article. The real volume characteristics of the aggregates Al 10-7-2 and A110-2-2 on the base of compressor П110 are used for correct comparison. While using TEW I-analyses method we came to the conclusion that the compressor aggregates are effective when operating with the refrigerants under consideration.
