Study to determine the existence of an azeotropic R22 "drop-in" substitute.
Author(s) : KIM M. S., MORRISON G., MULROY W. J., DIDION D. A.
Type of monograph: Booklet
Summary
This paper presents laboratory and computer simulation evaluation of two of the azeotropic refrigerant mixtures which were identified, HFC-134a with R290 (propane) and HFC-134a with R600a (isobutane), in a generic heat pump apparatus. A third mixture, HFC-134a with cyclopropane is examined by computer simulation only. The performance characteristics of these azeotropes were compared with pure CFC-12, HFC-134a, HCFC-22, and R290 at high temperature cooling and heating conditions. Use of liquid-line/suction-line heat exchange was evaluated. Extract from the table of contents: azeotropy in refrigerant mixtures; performance prediction; laboratory performance evaluation; performance results and discussion; flammability measurements.
