Performance Analysis of Refrigerants R134a and R1234yf Two Stage Compression Cycle with Two Condensers

Abstract:

With increasing of compressor high pressure, the cycle performance of R134a or the cycle of R1234yf has a downward trend. With increasing of the evaporating temperature, the cycle performance of R134a or the cycle of R1234yf has an increasing trend. With increasing of outlet temperature of condenser, the performance of R134a or the cycle of R1234yf has a downward trend. With increasing of intermediate pressure or discharge temperature, the performances of all cycles are decreased. Under same contrast conditions, the cycle performance of R134a is better than the cycle of R1234yf.
