PERFORMANCE ON THE SOLAR TOTAL ENERGY SYSTEM EXPERIMENTAL FACILITY WITH AUXILIARY HEATER.

This paper describes the computer simulation program developed for establishing the optimum design of solar total energy system with auxiliary heater and the characteristics of the experimental facility determined by using it. An experimental solar total energy system test facility of rated electric power capacity 15 kW and rated thermal supply capacity 45 kW has been developed and operated under various conditions. This facility has three operating modes with different solar radiation intensity and temperature conditions of the heat storage systems. Free operating mode is the combination of three modes. It has been found that the free operating mode is the most useful one, in terms of annual operating hours and electric output.
