Automotive Air Conditioning System Using HFC-134a Comparison of Refrigeration Cycle Characteristics of CFC-12 and HFC-134a 930229

As an alternative refrigerant for CFC-12, HFC-134a is the best choice in automotive air conditioning system.
Refrigeration cycle characteristics using HFC-134a have been previously reported, but most of those papers were confined to the differences of basic system performance between CFC-12 and HFC-134a.
So this paper emphasized the analysis on functional components. As a result, we have introduced the differences of refrigeration cycle characteristics which had not been acquainted well by now.
