Mechanical Heat Pump

The working principal of Heat Pump and Refrigerating Machine is the same and same components. Heat pump is a machine which delivers heat at temperature suitable for either domestic, industrial and commercial purposes. The majority of heat pumps operate on the vapour compression cycle using a refrigerant as working fluid. This Mechanical Heat Pump is fully sealed R-12 refrigerant system using water to water heat pumping principle.

This apparatus is used to perform the following experiments :
 Study of mechanical heat pump.
 To determine the COP of the unit.

 Compressor : Hermetically sealed, approx. 1/3 Ton cooling capacity.
 Condenser : Water cooled, shell & coil type of suitable capacity.
 Expansion Device : Capillary tube.
 Evaporator : Water cooled, shell & coil type of suitable capacity.
 Refrigerant : R-12
 Filter & Dryer of suitable capacity.
 Water circuit : For evaporator & condensor, thermometer & control valves.
 Pressure gauges : 2 Nos. for high and low pressure.
 Energy meter for compressor power measurement.
 Multi-channel digital temperature indicator - 7 Nos.
 Service valve : 3 Nos. (Indfos make)
 Ammeter : 1 No.
 Voltmeter : 1 No.
 Thermostat : 1 No.

The equipment is mounted on a sturdy frame with control panel.
