engineering recuitment UPPSC AE Mock Test 2024 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Vapour Compression (V-C) Cycle
The use of a single refrigerant in a simple vapor compression cycle for the production of low temperatures is limited by which of the following reasons?
1. Solidification temperature of the refrigerant
2. Extremely low pressures in the evaporator and large suction volumes if a high-boiling refrigerant is selected
3. Very high-pressure ratio, therefore a low coefficient of performance
