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 from 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.
EXPERIMENTATION:
- Determination of co-efficient of performance of the unit when working as water-to-water heat pump.
- To Construction of Energy balances for completed system over a range of operating conditions.
- To determine overall heat transfer co-efficient for condenser and evaporator.
UTILITIES REQUIRED:
- Electric supply 5A-220 V AC
- Water supply and drainage
- Floor area : 1.5 m x 1m
