摘　　要：建立了槽式聚光集热真空管装置的数学模型,并与实验结果进行了对比。理论计算结果与实验结果吻合较好,误差在5.2％以内,表明可用所建立的模型对聚光式真空管加热流体的性能进行分析。在太阳辐射强度及聚光面积变化的情况下,分析了通过聚光真空管内流体的性能特性。还给出了利用槽式聚光装置驱动太阳能吸附制冷的应用实例。A mathematic model of an evacuated tube heated by solar trough concentrating system has been established and verified with experimental data. The calculation based on the model is agreeable with experimental results, the errors between calculations and experiments are less 5 %, which indicates that the model could be used as predicting the properties of evacuated tube heated by solar trough concentrating system. The characteristics of fluid via evacuated tube, which is heated by solar concentration system, have been analyzed under the variation conditions of solar irradiation and trough concentrating areas. An example of solar solid refrigeration driven by solar trough concentrating system has also been given, which showed that the solar trough concentrating system will be of potential application in solar thermal conversion.
