综合考虑聚光型光伏&光热一体机在不同气候条件下,电池片的散热方案,研制了一套热交换系统,并对其进行试验研究。结果表明:采用层压技术将电池片与冷却器组合在一起,可把聚光光伏电池片的工作温度有效控制在60℃以下;利用冷却器的水介质同步收集无法转换成电能的太阳能,得到约58℃的温水;通过集热板对冷却器流出的温水进行二次加热,获得约78℃的高温热水。经过实测,掌握了一体机在不同季节,电池片工作温度的控制规律,一体机的光电和光热总效率达到60%以上,实现了高效率、低成本太阳能光伏&光热的综合利用。
Taking into account the cooling scheme of the concentrating photovoltaic and solar thermal integration machine under different climatic conditions and cell sheets, a set of heat exchange system was developed and tested. The results show that the combination of cell and cooler can effectively control the working temperature of the concentrating photovoltaic cell below 60 ℃ by using the laminating technology. The solar cell can not be converted into solar energy by using the aqueous medium of the cooler simultaneously, About 58 ℃ warm water; the collector through the cooler out of the warm water secondary heating, access to about 78 ℃ high temperature hot water. After measured, the control of one machine in different seasons, the operating temperature of the cell law, one machine photoelectric and light thermal efficiency of more than 60%, to achieve high efficiency, low cost solar photovoltaic & solar thermal comprehensive utilization.
