EFFECTS OF SUPERHEATING AND SUBCOOLING IN A VAPOR COMPRESSION REFRIGERATION SYSTEM WITH R507A REFRIGERANT
Öz
Vapor compression cooling systems are the most used and most efficient cooling method in industrial and commercial applications. The reason of these systems are preferred is that they reduce environmental impacts, provide energy efficiency and have economic advantages. In this article, the effects of superheating and subcooling on the system performance in the vapor compression refrigeration cycle (VCRS) using R507A were theoretically examined. The thermodynamic data used the calculation were taken from the Coolpack program. The performance analysis of the VCRS were made for different operating conditions. In the analyses, the evaporator temperature was changed between -5 and -25 oC, the condenser temperature was changed between 25 and 45 oC, and the superheat and subcooling temperatures were changed as 0, 3, 5 and 7 oC. In the analysis made depending on the change in evaporator temperature, superheat and subcooling temperatures, the highest COP value of the cycle is 3.71. In the analysis made depending on the change in condenser temperature, superheat and subcooling temperatures, the highest COP value of the cycle was found to be 4.367.
