Performance Analysis of Refrigerants R134a Two Stage Compression Cycle with Two Gas Cooler

Abstract:

With increasing of high pressure, the two stage compression cycle with two gas cooler has a downward trend. With increasing of the evaporating temperature, the two stage compression cycle with two gas cooler has an increasing trend. With increasing of outlet temperature of condenser; the two stage compression cycle with two gas cooler has a downward trend. With increasing of intermediate pressure, the performances of the two stage compression cycle with two gas cooler are decreased.
