The Best Condensing Temperature of Vapor Compression Refrigeration Cycle
Abstract: When the condensing temperature decreases, the refrigeration coefficient of refrigerator increases, which is the conclusion of the thermal-technical analysis on the refrigerator. The condensing temperature decreases with the decreasing of the natural environment temperature, while the natural environment temperature varies along with the seasonal variation and day-night variation. Therefore, many consider that the drop of environment temperature would inevitably increase the refrigeration coefficient of the refrigerator. However, hands-on experience proves that when the environment temperature causes the decrease of condensing temperature, in the early stages, the refrigeration coefficient of the refrigerator will increase continually. But after the condensing temperature drops to a certain degree, the refrigeration effect of the refrigerator will decrease instead. It is thus clear that there exists the best condensing temperature of refrigerator. This paper conducts theoretical analysis aimed at this phenomenon and calculates the best condensing temperature value of the vapor compression refrigeration cycle on the basis of R22 single stage compression basic theory.
