Product Description

Reverse Cycle Refrigeration Training System

layout, function and main components of a heat
  pump
- Measurement of relevant pressures, temperatures,
  flow rates, current and voltage
- Illustration of the thermodynamic cyclic process in a
  p-h state diagram
- Comparison of different operating modes
- Comparison of different expansion elements
  (expansion valve, 4 capillaries)

Technical Description
contains a hermetic compressor, 4 heat exchangers, 3 expansion valves and 4 different interchangeable capillaries. The unit can be operated in different modes. 11 manually operated valves allow corresponding changes to be made to the refrigeration circuit.
