Full Specification ( Water Cooler Trainer ):
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 cell. The stainless steel water tank is provided with insulation on air Sides and a door are provided at the top. Cold water can be taken out from a top provided and inlet water supply is controlled by a bail-operated top. Various measurements provided enable students to determine the theoretical and actual COP, power consumption, actual cooling capacity refrigerant flow and compressor volumetric efficiency of compressor.
