Type of article: Article

Summary

THE DEVELOPED EQUATION OF STATE IS EXPRESSED BY THE HELMHOLTZ FUNCTION AS A FUNCTION OF TEMPERATURE, DENSITY ANDCOMPOSITION, AND IS EFFECTIVE FOR A RANGE OF TEMPERATURES FROM 250 TO 500 K AND OF PRESSURES UP TO 10 MEGAPASCALS, WHICH CORRESPONDS TO THE DENSITY RANGE UP TO THE CRITICAL VALUE. THE CYCLE ANALYSIS ON THE HEAT PUMP AND REFRIGERATION SYSTEMS WAS THEORETICALLY CARRIED OUT, AND IT BECAME CLEAR THAT THE R22-R114 SYSTEM IS PROMISING FOR INDUSTRIAL HEAT PUMPS OR AIR CONDITIONING AND HOT-WATER-SUPPLY HEAT PUMP SYSTEMS. THE EFFECT OF CHANGE IN COMPOSITION ON THE THEORETICAL COPHAD THE SAME BEHAVIOUR AS THAT REPORTED BY EXPERIMENTAL TESTING.
