The aim of this to calculate the thermal efficiency of heat absorbing apparatus by comparatively studing a relationship between the experimental results and the calculated values obtained after the ideal formular for absorption heat are derved, when solar heat is absorbed to the circulation-type heat absorbing plate.
The thermal efficiency obtained from the experiment was found to be about 14 to percent. It was also shown that as the appartus used was placed in the east, there was a tendency that the absorbing plate facing the west was more effective in terms of thermal efficiency.
