Together with the training stands S4 and S1 the training stand S7 can be combined to form the pellet heating training system. With this high-tech teaching system, extensive knowledge can be imparted within the scope of training as a system mechanic for HVAC and for further training:
- Basic knowledge of biomass heating systems
- Expertise on pellet heating systems
- Knowledge of processes and interrelationships during the firing process and operation
- Expertise in planning, installation, commissioning and maintenance
The processes, procedures and the technical connections in a pellet heating system are visible in this teaching system and can thus be understood by the trainee. The operating states can be varied using potentiometers, so that errors and malfunctions can also be simulated.
Safe operation
The teaching system pellet heating works
without a real burning process. The operation is possible without danger, no
flue gases are produced, because the heat is generated by a heating
cartridge.
Measured values/sensors
Numerous measuring points and
sensors, including a lambda sensor, provide numerous possibilities for
conducting your own tests and evaluating measured values. Operating states,
errors and malfunctions are simulated via potentiometers.
With test instructions:
- Basic information on biomass heating systems
- Technical information on pellets heating technology
- Practical tasks and solutions
Pedagogic requirements
- Maximum learning efficiency from closely linking theory and the practical side of the subject with hands-on learning processes
- The contents of learning must be made "graspable" in both meanings of the word
- To avoid any waste of time in the learning organisation, all learning processes have to provided at the place of learning in a qualified and optimised manner, and the system technology must be designed for practical applications such that these processes can be realised in a mutually complementing way
- This calls for "integrated specialist classrooms" where both theory and the practical side of the area of technology concerned can be mediated
- The efficiency in conveying the knowledge and findings is part of the balanced concept which includes written information and exercises organised using modern media techniques, PC workplaces, experimental, laboratory and demonstration equipment to practice on
- All learning processes are designed in the context of "complete action" with the problem assignment (job, information), conditional analysis (analysis of the knowledge relevant to the organisation, planning), project realisation (execution, realisation, test record) and transfer (documentation, assuring the results, testing)
The teaching system heat pump with solar thermal energy consists of five mobile training stands, which can be combined in different ways depending on the teaching objective:
- Training stand S1: Geothermal Heat Source or Underfloor Heating
This training stand can be used as a source of heat in the configuration "Brine heat pump" (training stand 5) or as the heat sink in combination with the heat pump or the solar heat stand (training stands 3 and 4).
Operation with or without filling with water is possible here!
- 200-litre water tank
- 3 pipe systems (10, 20 and 30 metres in length)
- Integrated hot-medium meters to measure the overall flow, the hot and the cold outputs as well as the admission and return temperatures
- Bypass valve between the heating circuits for the experiments to bypass the three pipe systems
- Experiments on "hydraulic adjustment" with the three pipe systems routed in parallel using the volumetric flowmeters and throttle valves
- Training stand S4: Coupling Component Hydraulic Switch, Plate Heat Exchanger and Buffer Storage
This training stand is used for adaptation to the hydraulic conditions. The uses for the hydraulic switch, the plate heat exchanger or the heat exchanger integrated in the storage system are diverse.
- Hydraulic switch and plate heat exchanger are interchangeable using an exchangeable disc (the component not being used is fastened to the rear of the stand)
- Hydraulic switch: Stainless steel vessel (volume approx. 1 litre) Primary circuit and secondary circuit are at the same pressure but are not hydraulically coupled
- Plate heat exchanger: 16 exchange plates, exchanger performance 17 kW at 70/50°C primary and 35/45°C secondary
- Enamel reservoir for holding 160 litres of water, with integrated straight-tube heat exchanger
- Training stand S7: Pellet Heating
The new training stand is an addition to the teaching system heat pump with solar thermal and photovoltaic. The training stand S7 presents the processes and functions of a modern pellet heating system with original components.
