A complete domestic heating system can be set up using the trainer HL 353.02 together with a hot water generator, e.g. HL 353. Hot water passes through the radiators and heats the room air. The temperature is controlled by means of heating controllers.
HL 353.02 contains two heating circuits. Both heating circuits are equipped with commercially available heating technology control devices. Each heating circuit contains a circulating pump.
The simple heating circuit with one subcircuit contains two flat radiators and is controlled by a temperature-led controller. A 3-way mixing valve serves as actuator. A simulator is supplied for varying the outside temperature.
The heating circuit with two subcircuits contains four radiators and two heating controllers. Each subcircuit can be switched on or off by a controller using an electrically switched solenoid valve.
The trainer is supplied with hot water from the supply unit HL 353 and is connected to the feed and return flow connectors using hoses with quick-release couplings.
Measured values for temperatures, pressures, differential pressures and flow rates are recorded. For energetic calculations and evaluations, the heating circuit with two subcircuits additionally contains two heat meters.
