The quasi-azeotropic mixture of refrigerants R410A replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners. However, newer regulations have mandated the phase-down of refrigerants with a high GWP as R410A, and thus, new
substituting refrigerants and mixtures must be selected. Among the different possibilities, some manufacturers have been interested in mixtures such as R454C, composed of R32 and R1234yf (21.5/78.5), which has a GWP lower than the limit imposed by the new F-Gas regulation.
In this study, a variable-speed scroll compressor was tested working with both R410A and R454C at different operating conditions. From these tests, the compressor behavior with these refrigerant mixtures has systematically been analyzed in terms of compressor efficiency, volumetric efficiency, and working range.
