RC Heat Control And Distribution Module Refrigeration Training Equipment Didactic Equipment
This module aims and it concerns the study of two types of heating circuits with radiators: a central heating system with outdoor reset control of water delivery temperature and a distributed heating system with room thermostats, zone valves and heat counters.
TRAINING PROGRAM
• Procedures for water filling and air bleeding from the system
• Outdoor reset control: variation of hot water delivery temperature versus outdoor air temperature
• Determining the proportional band of the controller
• Examination of the control circuit hunting
• Determining the control circuit amplification
• ON/OFF control: room thermostat
• Analyzing the operation of the 3-way mixing valve and of the zone valves
• Determination of the characteristic of the 3-way valve
• Plotting the emission curve of a radiator
• Modality for counting and calculating the used thermal energy
• Determining the authority of mixing valve (optional item electronic flowmeter required)
TECHNICAL SPECIFICATIONS
