WATER COOLER TRAINER : PSAW-207RA
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.
