| Abstract [eng] |
Geothermal heat pump and solar energy are future technology in energy engineer. This project is relevant not only to the scientific direction, but also in the practical application. For this research was chosen analysis and modernization of country side house with existing heat pump system. This work is accomplished not only theoretical aspect, with calculations, but also with the real practical aspect, when all the hypotheses and objectives fully implemented and applied in real terms and practices. Also, all modernizations are fully tested in real conditions. The goal of the project is to evaluate existing design weaknesses with new trends and opportunities. One of the secondary problems are raised by the existing evaporator structural imperfection. At this project was widely discussed evaporator types, parameters, calculation methodology. And after all it was selected individually for heat pump system requirements. All design of the evaporator was decided to make specially for this project, due to lack of analogues in field. It was presented with all manufacturing and assembly options and technology. After evaporator was assembled it was fully tested in practice. The main issue raised at this project was followed by the regeneration of the soil and accumulation of surplus energy for the cold season. This issue was discussed with various options and regeneration methods, which lead to selecting and applying solar collector. Which were carried out with various energy calculations and selections, implemented mathematical calculations and measurements, and all information with tests was compared with analogue cases in other countries. Also, was done analysis of horizontal ground heat exchanger, various options and customization techniques. Currently existing groundwater heat exchanger was evaluated as optimal and appropriate not only for heat pump operation, but also for excessive heat accumulation. All this combined system has been fully tested under realistic operating conditions. After all the tests in the field were able to reach its target, when during the summer soil was not only fully regenerated and restored to its original thermal state, but also managed to accumulate relatively substantial amounts of energy for the winter seasons. |
