Utilization System of Heat Storage Type Solar Energy in Hainan Tropical Environment
Journal Title: 河南科技大学学报（自然科学版） - Year 2017, Vol 38, Issue 2
Abstract
Aiming at the high cost of solar heat utilization in Hainan province,a solar energy utilization system was established,which met the tropical environment features of Hainan province. The distribution rule of solar radiation intensity in Hainan province was studied by collecting monthly average amount of solar radiation from representative cities of Hainan province. The solar energy utilization system was designed by adopting heat storage material and the sensible heat thermal storage mode. According to the distribution rule of solar radiation intensity in Hainan province,two kinds of improved schemes for condenser were put forward,which were single-sided concentrator( with mechanical gears and clockwork) and combined type condenser. The solar energy utilization system reduced the effect of the solar azimuth variation on the lens light gathering efficiency,and improved the gathering efficiency of Fresnel lens. In order to simplify the system design process,the structural optimization design for clockwork was conducted. Through analyzing the energy consumption between the heat storage type solar utilization system and common household rice cooker,the reasonability of structure design of the system was validated. The results show that the designed heat storage type solar energy utilization system has a good effect of energy conservation and environmental protection.
