ET 101

Basic Heat Pump Demonstrator

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.
