Capacity: 500 Watt, Refrigerant: R-134a
List of Experiments:
- To study various components and controls used in heat pump.
- To evaluate gross heat rejection of the heat pump.
- To calculate actual & theoretical C.O.P. of the system.
- To plot system performance on p-h chart.
The heat pump test rig is a self-contained unit. All the components are mounted such that its operation and working can be easily understood. The required controls for Temperature, pressure, and overload are provided. It uses a hermetically sealed Compressor, heat rejection chamber, heat absorption chamber, and apparatus to measure the heat gain and heat loss.
