HEAT PUMP TEST RIG

Description:
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.
