摘要
综合考虑聚光跟踪光伏&光热一体机在不同气候条件下的工作状况,设计一套光热装置,解决聚光光伏电池板的温升问题,并将部分无法转换成电能的太阳能以热能的形式收集起来。通过测试验证,该光热装置可有效解决聚光光伏电池片的散热问题,还可收集太阳光热,获取利用价值较高的热水,从而达到高效、低成本太阳能光伏&光热的综合利用;在不需热水的条件下,通过辅助内循环控制,该光热装置还可确保聚光光伏单独运行;考虑阴雨天气,通过手动加热控制,可确保阴雨天气的热水供应。
It is necessary to design one thermal energy converter and heat water exchanger system which decreases temperature rising in focus-solar photoelectric battery cells and collects synchronously thermal energy from solar en- ergy those energy incapably converted into electric energy. Hereafter numerable experiments to this system have been conducted, the converter/exchanger system can solve efficiently problem of heating from battery cells and col- lect simultaneously solar energy such as the more use value heated water is obtained, thereby solar photovoltaic/ thermal complex utilization will be achieved with higher effect and lower cost; moreover focus-solar photoelectric op- eration can also be kept running separately by supplementary internal circulating control in the integration device while hot water is not demanded. In particular in the overcast and rainy day, hot water supply is also guaranteed momentarily as long as it is manually selected to heat.
