Experimental Investigation Of Water Chiller By Using Conical Coil And Helical Coil Evaporators In A Vapour Compression Refrigeration System

The performance of helical and conical coil evaporators in a vapour compression refrigeration (VCR) system is compared in this study. The coefficient of performance (COP), temperature variation, condenser heat rejection, and refrigeration effect (RE) are among the key performance indicators that have been examined. According to the experimental results, the conical coil design greatly improves system performance by achieving higher theoretical and actual COP values, more stable temperature regulation, better heat rejection, and a larger refrigeration effect. These results lend support to the use of conical coil evaporators in refrigeration systems to increase efficiency and reduce energy consumption.
