Water Cooler Test Rig

The apparatus consists of a storage water tank, embraced by evaporator coil of the cooling unit, cooling cycle comprises of a hermetically sealed compressor, air cooled condenser, a capillary tube as expansion device and an evaporator coil.  The trainer is designed for the study of features of a Water Cooler Trainer. It has a facility to measure various parameters like temperature at different points, pressure at different points, refrigerant flow rate, etc. Various measurements provided enables students to determine the theoretical and actual COP, power consumption, actual cooling capacity refrigerant flow and compressor volumetric efficiency of compressor.
