THERMODYNAMIC EVALUATION OF REFRIGERANTS IN THE VAPOUR COMPRESSION CYCLE USING REDUCED PROPERTIES.

Author(s) : MCLINDEN M. O.

Type of article: Article, IJR article

Summary

BY INVESTIGATING IN REDUCED CO-ORDINATES A CHARACTERISTIC REFRIGERANT AND DEVIATIONS FROM IT, VIRTUALLY ALL POSSIBLE FLUIDS ARE CONSIDERED. THE MOST IMPORTANT FACTOR IN DETERMINING PERFORMANCE IS CRITICAL TEMPERATURE. MOST PROPERTIES INVOLVE A TRADE-OFF BETWEEN HIGH COP AND HIGH HEATING OR COOLING CAPACITY, HOWEVER THERE IS AN OPTIMUM HEAT CAPACITY AND A HIGH CRITICAL PRESSURE INCREASES SYSTEM CAPACITY WITH NO PENALTY ON COP. THE ANALYSIS WOULD BE USEFUL IN FINDING FLUIDS FOR HIGH TEMPERATURES, BUT REVEALS THAT FLUIDS SUPERIOR TO PRESENT REFRIGERANTS ARE NOT LIKELY FOR LOWER TEMPERATURES.
