To determine the COP and Tonnage capacity of the chilling plant.

Apparatus: – Compressor, Condenser, Evaporator, Capillary Tube, Ammeter, Voltmeter.

Theory: -

The apparatus consist of a hermitically sealed compressor which is fitted on the base of a M.S stand on a wooden stand. The compressed refrigerant from the compressor flows towards the air cooled finned condenser. After the condenser condensed refrigerant is collected in the receiver tank and from receive it passing through a filter drier and capillary tube and enter into evaporator (cooling coil) unit. Evaporator unit is a shell and tube type heat exchanger, which consist of stainless steel vassal and evaporator coil is wounded in this vassal (tank) an arrangement is provided to flow water to be chilled in this tank.
