Pona O. Increase in efficiency of the combined heat supply system with solar roof

The mathematical model of the heat supply system with solar roof was created and the mathematical modelling of its operation was conducted, which enabled the determination of the thermal accumulative properties of the solar system. The schematic solutions of various structures of solar roof were developed. The complex of studies in relation to the efficiency of the heat supply systems with solar roof depending on the incidence angles, heat flow intensity, wind velocity and direction was conducted. The graphical and analytical dependences were obtained involving their usage for engineering calculations of the solar systems. The method of engineering calculations and computer program for determination of parameters of the solar heat supply system with different designs of solar roof and options of its usage in the combined systems were developed. The economic efficiency of solar roof usage in the heat supply systems was determined.
