Description
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

• Steel structure mounted on wheels, painted and treated in the oven
• Colour silk-screen-printed schematic diagram of system hydraulic circuit with warning LEDs
• Central heating system with 2 radiators, 1 flowmeter, 1 flow rate metering device, 1 recirculation pump, 1 check valve, 1 three-way motor-driven valve controlled by outdoor reset controller provided with outdoor air and water delivery temperature sensors, pressure gauges
