ShareSoft optimization test results of R32-R125-R134a (10-70-20%) compared to R502.
Author(s) : LINTON J. W., SNELSON W. K.
Summary
Zeotrope R32-R125-R134a (10-70-20%) is a long-term, zero-ozone depletion potential replacement for low-temperature refrigerant R502. The tests for comparison with R502 were carried out under controlled conditions in a well-instrumented alternative refrigerant test facility. Test data were used to compare important compressor performance characteristics including shaft power, pressure ratio, and compressor discharge temperature. System performance characteristics were also measured, including evaporator capacity, refrigerant mass flow, and cooling COP. The effect of additional liquid subcooling on the evaporator capacity and COP was also evaluated.
