A Case study of Exergy Losses of a Ground Heat Pump and Photovoltaic Cells System and Their Optimization

The aim of this scientific research is to experimentally determine the exergy losses a ground heat pump and further optimization for more efficient use operating modes improvement individual structural elements. In addition, it proposed photovoltaic panels as backup power source experimental installation under study. exergetic are calculated, not only itself, with R407C refrigerant. methodology consists in comprehensive assessment flows, their using new methods approximation piecewise linear functions, development prerequisites anergy one components type analysis efficiency low-potential energy sources. As result processing data, values Coefficient performance (COP) 4.136, temperature lower 0.0253 upper 0.155, 0.62, total loss specific 24.029 kJ/kg were obtained. Controllers Modbus protocol used data collection. Matlab Simulink was process data. When carrying out procedure optimizing selecting several minimal losses, an important role given mathematical statistical method increasing shown, first all, based on due exergo-anergetic evaluation modes. authors present measurement errors plant parameters form 3D Gaussian curve, which becomes possible when applying measurements.
