HEU Unit For Studying  Heating Elements Refrigeration Training Equipment Vocational Training Equipment

This module aims and it concerns the study of three types of heating elements: radiant floor panels fed, steel radiators, manually controlled fan-coil.
TRAINING PROGRAM
• Procedures for water filling and air bleeding from the system
• Plotting the emission curves of the heating elements
• Analyzing the operation of the 3-way mixing valve and of thermostatic valves
• Determination of the characteristic of the 3-way valve
• Proportional control: radiant system delivery temperature control
• Determining the proportional band of the controller
• Modality for counting and calculating the used thermal energy
• Determining the authority of the mixing valve (optional item differential pressure gauge required)
