Abstract
The objective of paper is to analyze the performance of the Vapour Compression Refrigeration (VCR) system by change the profile of condenser coil and with sub cooling system. An experiment is conducted on VCR system with different condenser profiles and also with sub cooling system at steady state evaporator temperature and calculated mass flow rate of refrigerant, refrigeration effect, works done and COP. From results of experiment, Refrigeration Effect in case of helical coiled condenser is increased by 3 kJ compared to straight coiled condenser and Refrigeration Effect in case of helical coiled condenser with sub-cooling is increased by 15.3% compared to helical coiled condenser without sub-cooling. COP in case of helical coiled condenser is increased by 20% compared to straight coiled condenser and COP in case of helical coiled condenser with sub-cooling is increased by 9.7% compared to helical coiled condenser without sub-cooling.
