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 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)

This training stand can be used as a source of heat in the configuration "Brine heat pump" (training stand 5) or it can connected with the heat sink circuit, optionally combined with the buffer feeder

• Hybrid collector from “Solarzentrum Allgäu”
• Circulation pump WILO RS25
• Solar heat regulator Steca TR 0301sc
• Electric components (inverter, modules and connecting cables)

• To understand the function of a hybrid collector on the basis of experiments and measured values
• To plan heat pump systems with hybrid collectors as an energy source for the heat pump
• To understand the effect of the temparature profile on the thermal collector and PV module
• To record and analyse measured values
• To plan and execute an emergency power system for a a circulation pump with regulator
• Sensible use of PV electricity in off-grid systems or in the emergency power system
• Experimental derivation
• To understand the physical process of a hybrid collector in thermal energy extraction through the brine circuit of a heat pump
• To understand the process of water extraction though condensation at the hybrid collector
