Abstract [en]

Theoretical cycle data and heat transfer of HFO-1234yf were calculated and compared with those of R134a. Drop-in tests for R134a and HFO-1234yf were carried out using refrigeration unit of a hermetic rotary compressor of 550 W nominal output power and plate heat exchangers. Results of the evaporator cooling effect and heat transfer, COP, and compressor efficiency at a defined condensation temperature and similar evaporation temperatures for the two refrigerants were calculated and compared.
