Mechanical Heat Pump Apparatus

Mechanical Heat Pump Apparatus
Mechanical Heat Pump Apparatus for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers
The components of the heat pump and its instrumentation are mounted on a high quality ABS plastic panel.
The Mechanical Heat Pump consists of a hermetic compressor, an insulated coiled concentric tube water cooled condenser, a liquid receiver, a thermostatically controlled expansion valve and air heated evaporator.
Mechanical Heat Pump components are clearly but compactly arranged in a manner similar to that used for many domestic air-water heat pumps and all are visible from the front of the unit.
The operating cycle is as follows:
Slightly superheated Refrigerant vapour enters the compressor from the evaporator and its pressure is increased. This brings about a rise in temperature and the hot vapour enters the water cooled condenser. Mechanical Heat Pump is given up to the cooling water and the refrigerant condenses to a liquid before passing to the liquid receiver and then the expansion valve.
Experimental Capabilities of Mechanical Heat Pump Apparatus:
    Determination of power input, heat output and coefficient of performance.
    Production of heat pump performance curves over a range of source and delivery temperatures.
    Plotting the vapour compression cycle on a p-h diagram and comparing this with the ideal cycle.
    Determination of energy balances for condenser and compressor.
    Production of heat pump performance curves based on properties, at a variety of evaporating and condensing temperatures.
    Estimation of the effects of compressor pressure ratio on volumetric efficiency.
