Comparison of compressor efficiency between rotary and scroll type with alternative refrigerants for R22.

Author(s) : KATO T., SHIRAFUJI Y., KAWAGUCHI S.

Summary

The efficiency of compressors optimized for each refrigerant is theoretically figured out, and it is also experimentally confirmed. As the results, the upper limit of cooling capacity range, in which efficiency of rotary type is higher than that of scroll type, is about 2,344 watt with R22 and R407C. In the case with R410A, rotary type is superior to scroll type in the range approximately up to 7,032 watt. The study shows that the range in which rotary types operates more efficiently than scroll type will expand up to small capacity range of unitary air conditioners in the case with R410A.
