Thermodynamic analysis of optimum condensing temperature of cascade-condenser for CO2/NH3 cascade refrigeration systems.
Author(s) : LEE T. S., LIU C. H., CHEN T. W.
Summary
This study analyses a cascade refrigeration system utilizing carbon dioxide and ammonia as refrigerants, to find the optimum condensing temperature of the cascade-condenser in which the system attained the maximum COP and the minimum exergy destruction. The results indicate that the optimum condensing temperature of the cascade condenser is -18°C under the condensing temperature of 35°C and the evaporating temperature of -50°C. The analytical results of this study are useful for the design and development of CO2/NH3 cascade refrigeration systems and related equipment.
