New HFC/HFO Blends as Refrigerants for the Vapor-Compression Refrigeration System (VCRS)

In this work, which is related to the current European Parliament Regulation on restrictions affecting refrigeration, four new three-component refrigerants have been proposed; all were created using low Global Warming Potential(GWP) synthetic and natural refrigerants. The considered mixtures consisted of R32, R41, R161, R152a, R1234ze (E), R1234yf, R1243zf, RE170. These theoretically tested with a 10% step in mass fraction triangular design. analysis covered two theoretical cooling cycles at evaporating temperatures 0 ?30 °C, 30 °C constant condensing temperature. final stage work was determination best mixture compositions by thermodynamic operational parameters. R1234yf–R152a–RE170 weight share 0.1/0.5/0.4 determined be optimal for potentially replacing existing
