MECHANICAL HEAT PUMP TRAINER-

MECHANICAL HEAT PUMP TRAINER

[CAPACITY: 500 WATT, REFRIGERANT: R-134 a]

List of Experiments:

1. To study various components and controls used in heat pump.
2. To evaluate gross heat rejection of the heat pump.
3. To calculate actual & theoretical C.O.P. of the system.
4. 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.
