Second Law Analysis of an Automobile Air-Conditioner With R22/R124/R152a Refrigerant Mixture
Keyword(s):
In this paper the irreversibilities and second law efficiency of an automobile air-conditioner with R22/R124/R152a refrigerant blend have been carried out. The engine is 1,300 c.c. capacity and operated at different compressor speeds between 13–55 rps. The irreversibility at each component of the air-conditioner increases with higher compressor speed. Significant irreversibilities have been found at the condenser and the compressor. In the case of the cycle second law efficiency, the unit with 30% mass fraction of R22 shows better performance than those with 20 and 40% mass fraction.
