| Abstract: | Instantaneous efficiency and daily average efficiency of evacuated tubular solar heater waters are contrasted with theoretical values by model of calculation and experimental data. The results show that the model is a correct model. Instantaneous efficiency of evacuated tubular solar heater waters and flat plat solar heater waters are also contrasted with theoretical values, their important differnece on the instantaneous efficiency curve is analyzed. |
