摘要
针对海南省太阳能热利用成本高的问题,探索了一种符合海南省热带环境特点的太阳能利用系统。收集整理海南省代表性城市月平均太阳总辐射量,分析了海南省太阳辐射强度分布规律。采用储热材料和显热储热方式设计了太阳能利用系统。结合海南省太阳辐射强度分布规律,设计带有机械齿轮和发条装置的单面聚光器与"组合式"聚光器,有效降低了因太阳方位变化对透镜聚光效率的影响,提高了菲涅尔透镜的聚光效率,并对该系统的发条装置进行了结构优化,简化了系统设计过程。对比分析该储热型太阳能利用系统与普通家用电饭煲的能耗量,验证了系统结构设计的合理性。研究结果表明:所设计的储热型太阳能利用系统具有良好的节能环保效应。
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.
