Influence of refrigerant R1234yf as a substitute for R134a on a perfect refrigeration cycle and exchanger efficiency
Languages of publication
This paper analyses the R1234yf refrigerant as a substitute of R134a with respect to its thermodynamic properties. For the assumed calculation parameters, identical evaporation and condensation temperature, ideal refrigeration cycles with R1234yf and R134a were compared. Moreover, for an actual car evaporator, thermal calculations were performed for the exchanger and the theoretical efficiency parameters of both refrigerants were provided.
