Development of Compressor Material Technology for HFC134a Use

چکیده
HFCI34a was selected for the alternative refrigerant for CFC12 because of its excellent properties like thermodynamics. But there were several problems like immiscibilitiy with oil to replace CFC12 by HFC134a. In order to solve these problems, we developed new polyol ester refrigeration oil which had good miscibility with HFC134a and excellent thermal stability and lubricity as well. To apply polyol ester oil into refrigeration system, we evaluated compatibility with insulation materials and develop contamination control technology to reduce sludge deposition in system. In this paper we introduce newly developed polyol ester oil and its properties, material technology and chemical specifications 111 refrigeration system for HFCI34a use.
