Heat Pump and the refrigerating machine basically work on one and the same principle and with the same components. Heat pump is a machine, which delivers heat at a temperature suitable for domestic, Industrial and Commercial purposes. By added work input form the motor or engine it extracts heat from low-grade source. In many circumstances heat pumps can make valuable contribution to energy conservation. The majority of heat pumps operate on the vapour compression cycle using a refrigerant as the working fluid. Heat pump is fully sealed R-134A refrigerant system using water to water pumping principle. The equipment produces realistic results and has low thermal inertia so that unit stabilises very quickly and enables student’s maximum experimentation.
