Abstract
The photovoltaic/thermal(PV/T) collector is a critical component of the photovoltaic thermal system. Performance quality directly decides high or low of comprehensive utilization of solar energy. Therefore,the design of the PV/T collector has an important role on research in the performance of the photovoltaic solar-thermal system. In this paper,the analysis structure and heat resistance of the PV/T collector,simulation of the thermal performance of the PV/T collector in aluminum tube plate under 75 kinds of working conditions,including irradiance types,structure size and flow conditions by using the Fluent software,and optimal design for the PV/T collector,according to the result of design to build the test rig,the collection efficiency and power efficiency of PV/T collector were studied. The results showed that the better cooling water flow rate(Q=0.008kg/s) and area ratio(D/W=0.4) of the collector were obtained. With the increase of the normalized temperature difference,the photoelectric efficiency and the collection efficiency of PV/T collector decreased. The maximum error of the predicted values and experimental values of the photoelectric efficiency was 22.5 percent. The average collection efficiency is 0.63. The county thermal efficiency reaches 0.75.关键词
