في منطقة ورقلة (PTC) تحسين الكفاءة الضوئية والحرارية للمركز الشمسي الاسطواني القطع مكافئ

Abstract

The parabolic Trough Collector (PTC) is considered one of the most important solar concentrating systems and the most effective in producing steam in thermal and electric power plants and exploiting it for various industrial and domestic purposes. In order to improve the optical and thermal efficiency, we studied the effect of two factors, namely the solar tracking system and the mass flow This experimental work included The possibility of exploiting the thermal energy generated from the parabolic cylindrical solar center to raise the temperature of the outlet of the absorbent tube and is positively affected by reducing the mass flow, as the water exit temperature at the demise for a mass flow reached 1L/min and for tracking with one rotation axis T=52°C Where the working principle of the PTC depends on the concentration of direct solar radiation
