Performance Analysis of Refrigeration System by Variable Adjusting Amounts of Refrigerant Charging

This study is the performance variation analysis of refrigeration systems by changing the amount of refrigerant charging quantity according to adjusting the refrigerant charging 600gram, 800gram, and 1,000gram with vapor compressional refrigeration training equipment. At 600g refrigerant charging, the superheat, outlet temperature of compressor, refrigeration effect, coefficient of performance, refrigeration capacity were higher than 1,000gram refrigerant charging, while at 1,000gram refrigerant charging, evaporating and condensing pressure, compression work, were higher than 800gram refrigerant charging condition, Thus, we could see changes of the refrigeration system performance s factor the affect of amount of between resonable refrigerant charging and over charging conditions.
