FLUIDS FOR HIGH TEMPERATURE HEAT PUMPS.

Author(s) : BERTINAT M. P.

Type of article: Article, IJR article

Summary

THE THEORETICAL PERFORMANCES OF SOME 250 POTENTIAL WORKING FLUIDS IN COMPRESSION HEAT PUMPS CONDENSING AT 423 K (150 DEG C) AND EVAPORATING AT 373 K (100 DEG C) HAVE BEEN PREDICTED, USING EXPRESSIONS FOR COP AND MINIMUM SUPERHEAT THAT INVOLVE ONLY EASILY ACCESSIBLE PHYSICAL PROPERTIES. EXPECTED CORRELATIONS WERE FOUND BETWEEN COP AND CRITICAL TEMPERATURE, BETWEEN SPECIFIC COMPRESSOR DISPLACEMENT AND NORMAL BOILING POINT AND BETWEEN CONDENSING PRESSURE AND NORMAL BOILING POINT, BETWEEN MINIMUM SUPERHEAT AND MOLECULAR WEIGHT AND CRITICAL PRESSURE. THE DESIRABLE BASIC PROPERTIES OF A HIGH TEMPERATURE HEAT PUMP FLUID ARE DEDUCED.
