冷却水流量变化对板管式光伏光热系统的性能影响探析

Analysis on the influence of cooling water flow change on the performance of PV/T system

在板管式光伏光热系统进行使用时,为了避免过热会采用冷却水来进行冷却,但是在不同的冷却水流量下,对板式光伏光热系统的冷却效果却有着很大的差异,不仅如此,冷却效果还会直接影响板式光伏光热系统的各项性能,如果没有做好冷却工作,就会导致整个系统的工作性能下降,甚至会影响整个系统的正常运转。为了更好地研究其中存在的一些原理,文章将通过改变冷却水的流量,来观察板式光伏光热系统之中各部分组件的温度、发电功率以及整个系统的热效率,从而探究出更符合要求的冷却水流量,实现对于板式光伏光热系统各项性能更好的控制。

In order to avoid overheating,cooling water will be used to cool the plate photovoltaic photothermal system,but under different cooling water flow rate,there are many great differences in the cooling effect of the plate photovoltaic photothermal system.If the cooling work is not done well,the working performance of the whole system will and even affect the normal operation of the whole system.In order to better study some of the existing principles,this paper will observe the temperature,power generation and thermal efficiency of each part of the plate photovoltaic photothermal system by changing the flow rate of cooling water,so as to explore a more suitable cooling water flow rate and achieve better control of the performance of the plate photovoltaic photothermal system.
