Heat Distribution And Control In Heating Systems

The simple heating circuit with one subcircuit contains two flat radiators and is controlled by a temperature-led controller. A three-way mixing valve is the actuator. A complete domestic heating system can be set up using the trainer together with a hot water generator, Hot water passes through the radiators and heats the room air. It contains two heating circuits. A simulator is supplied for varying the outside temperature. The heating circuit with two subcircuits contains four radiators and two heating controllers. Both heating circuits are equipped with commercially available heating technology control devices. Solenoid valves enable control of the heat distribution in the two subcircuits. Each heating circuit contains a circulating pump.
