DESCRIPTION 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 lowgrade 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 R134A refrigerant system using watertowater pumping principle The equipment produces realistic results and has low thermal inertia so that unit stabilises very quickly and enables students maximum experimentation
EXPERIMENTATION Determination of coefficient of performance of the unit when working as watertowater heat pump To Construction of Energy balances for completed system over a range of operating conditions To determine overall heat transfer coefficient for condenser and evaporator
