Decisive for the quality of the training given is that practical exercises are possible and that measurements with real equipment can be performed. It is only by literally "grasping" and "touching" that the technical processes will be understood, and hence can be managed as well. That which cannot be directly observed and sensed, has to be perceived by suitable experimental measurements.

Pedagogic requirements

• Maximum learning effi ciency from closely linking theory and the practical side of the subject with hands-on learn-ing 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 qualifi ed and optimised manner, and the system technology must be designed for practical ap-plications 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 technol-ogy concerned can be mediated
• The effi ciency in conveying the knowledge and fi ndings 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, in-formation), conditional analysis (analysis of the knowledge relevant to the organisation, planning), project realisation (execution, realisation, test record) and transfer (docu-mentation, assuring the results, testing

• Experimental set-up (download)  

This training stand constitutes the central element of the teaching system.

Besides the heat pump, the stand contains all the power supply points for the other training stands. With the brine and heating circuit connection, the circulation pumps and the safety devices are already installed for the professional operation of a heat pump.

• Conventional heat pump with evaporator, scoll compressor, liquifier and expansion valve in line with state-of-the-art technology
• Permanently fitted cold circuit (not accessible for experimental interventions), refrigerant R134a
• Manometer for sensing and measuring physical events in the cold circuit
• Digital thermometers for measuring the temperatures in the cold circuit downstream of the evaporator, air compressor, liquifier and expansion valve
• Low and high-pressure control devices, energy measuring device, high efficiency circulation pumps and other components
• Power supply, measuring and switching unit with RCT, main fuses, energy measuring device, control-circuit fuse and contactor relay

• Understand the technical system requirements for heat-pump heater systems and solar-heat equipment
• Knowledge of the electrical, hydraulic and control require-ments needed for operation, using a heat-pump heater system or solar-heat equipment as an example
• Knowledge of the physical processes in the cold circuit of a heat pump
• Systematic approach to commissioning a heat-pump heater system or solar-heat equipment
• Capability to plan, set up and commission heat-pump and solar-heat heater systems in a concerted manner
• Capability to prepare test records for heat-pump heater systems and solar-heat equipment
• Skills in recording measurements and evaluating the results from electrical and hydraulic processes using a heat-pump and solar-heat systems as examples
• Understanding the processes to optimise the energy in heater systems using heat pumps and solar heat
• Knowledge of the terms and operating resources used for heat-pump and solar-heat systems
• Capability to judge the electrical and hydraulic values measured in heat-pump heater systems and to plan any thereby re-lated process changes
• Understanding of the technical controls and optimisa-tion of the energy in the circulation pumps used in heater systems
• Skills for optimising energy processes in heater systems
