ET 101: Basic Heat Pump Demonstrator

Print Ask to this Articlel

Basic Heat Pump Demonstrator

Basic Heat Pump Demonstrator

Product Details


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.

Learning Objectives / Experiments
· 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

Features
Functioning model of a water-to-water heat pump
Measurement of process pressures
