Technique for calculating the efficiency of operation for solar collector systems

According to the proposed method, the optimal connections of collector systems were investigated, and the hydrodynamic characteristics and efficiency of the solar water heating installation were determined. A graph of the heating versus time was plotted for various values of the number of collectors. The dependence of the change in the heat transfer coefficient of the tank-accumulator on the thickness of the heat-insulating material is obtained. On the basis of a mathematical model, a computer program was compiled in the Delphi 7 environment, which allows to determine the main characteristics and parameters of a solar water heating installation.
