Both in the electrical and HVAC crafts, more emphasis must be placed on teaching renewable energy technologies in initial and continuing vocational training. The demand for efficient and optimised process design applies to teaching and learning concepts as well as to all energy-related applications! For the methodology and didactics of learning processes, action-oriented concepts in particular meet these requirements.
For this reason, Christiani offers training stands developed for vocational training, which enable an optimal professional qualification in the field of solar thermal and heat pump technology with electro-technical and hydraulic expertise!
These training stands can be combined in different ways, depending on the training objective. The S5 training stand can only be used in conjunction with other training stands.
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)
-
Brine heat pump with all hydraulic and electrical connections, temperature and pressure displays in the refrigeration and heating circuit
-
The classic brine heat pump is constructed with high-quality operating equipment such as a scroll compressor, plate heat exchangers, expansion valve and other components.
-
R 407 c is used as refrigerant.
-
For metrological evaluation, two manometers indicate the pressure in the high and low pressure part. The pressure scale also shows the corresponding evaporating temperature for R 407 c. In addition to the main switch, additional switches for the brine and heating circuit circulation pump and the connection sockets for these are located on the switch and measuring board.
-
For safety monitoring, control lamps indicate faults in the presostats and thermostats in the heating and cooling circuit. The temperatures in the cooling circuit are registered by digital temperature displays with additional min/max indication.
-
All connections to the cold source and heating circuits are made using self-sealing quick couplings. For flushing and filling the circuits, appropriate fittings with quick couplings are fitted.
-
With the heat pump training stand, all service, testing and operating tasks for heat pumps can be carried out in conjunction with the other training stands. The entire training system is the result of 20 years of experience in training on heating systems with regard to energy efficiency.
-
With the practical application examples of the heat pump system a maximum of know-how transfer and qualification success for this renewable energy sector is achieved in a short training period.
