Product Description

Basic Heat Pump Demonstrator

Familiarisation with the function of a heat pump / refrigeration unit
· Familiarisation with the main components of a heat pump
· Measurement of process pressures
· Thermodynamic cycle

Technical Description                                    
 This clearly laid out model demonstrates the principle of operation of a simple heat pump. Heat is transferred from one cylinder to another via heat exchange coils. The trainee can feel the "cold" and the "heat". The unit is equipped with 2 large manometers for displaying the refrigerant pressures and 2 thermometers to indicate the temperatures in the water tanks.
The refrigerant used is environmentally friendly.
