Investigation of different parameters effect on nocturnal radiative cooling

In this research a nocturnal radiative cooling system is studied. Firstly the nocturnal radiative cooling potential in Zahedan climate is considered. Then the effect of water volume flow rate and storage tank volume on cooling load is investigated. Thermal stratification model is used for the storage tank modeling. In this article, the effect of the thermal layer numbers on the result accuracy is studied. The article results show that Zahedan has high potential for using nocturnal radiative cooling. On the other hand, the considerations show that the water volume flow rate increasing causes the stored water temperature decrease. Also when storage tank capacity increases, the stored water temperature increases, but when the amount of water increases, it can help to save more cooling at night. Finally assuming the thermal layer number between 3 and 10, can decrease the computation’s error.
