This module has been specifically designed for educational aims and it concerns the study of three types of heating
elements:
• radiant floor panels fed at low temperature with 3-way mixing valve and continuous control of delivery temperature
• steel radiators with temperature control via thermostatic valves mounted on each radiator
• manually controlled fan-coils.
TRAINING PROGRAM
• Procedures for water filling and air bleeding from the system
• Plotting the heating elements emission curves
• 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 mixing valve authority (optional item electronic flowmeter required)
