摘要
设计采用三种管路结构的PV/T集热器,对夏季与冬季的PV/T系统进行实验测试,通过COMSOL对三种管道形状的PV/T集热器进行温度场仿真分析。结果表明:夏季室外温度为24℃时,采用圆角方管的太阳能集热器光热效率可达到44.29%,直角方管41.78%,传统的圆管38.43%;冬季室外温度为1℃时,圆角方光热管效率38.74%,直角方管36.45%,圆管35.16%;采用方管时可更有效的降低光伏板温度,使光伏板温度6min左右降至平稳,圆管集热器需8min左右,并提升光伏板的光电效率。
PV/T collectors with three pipe structures were designed and tested in summer and winter.The temperature field of PV/T collectors with three pipe shapes was simulated and analyzed by COMSOL.The results show that when the outdoor temperature is 24℃in summer,the photothermal efficiency of the solar collector using square tube with rounded corner,square tube with rectangular Angle and traditional round tube can reach 44.29%,41.78%and 38.43%.When the outdoor temperature is 1℃in winter,the efficiency of rounded square tubes is 38.74%,rectangular square tubes 36.45%and round tubes 35.16%.Square tube can reduce the temperature of photovoltaic panel more effectively,so that the temperature of photovoltaic panel can be reduced to a stable about 6min,round tube collector needs about 8min,and improve the photovoltaic efficiency of photovoltaic panel.
