statistical study of seasonal storage solar system usage in iran

The seasonal storage solar systems set for greenhouse use, are capable of storing thermal energy in summer and use it in winter with special capacity. the main component of the system consists of solar thermal collectors and a sensible heat storage device which is buried under soil and uses water as storing media. the main aim of this study is to investigate the possibility of using this system in iranian greenhouses, regarding the criteria that affected the system performance. this is also compared with same systems in shanghai and lisbon. this case study focuses on tehran, shiraz and urmia, which are cities chosen from different ecosystems. applying tukey grouping method, the study showed that urmia and tehran that are respectively from iran’s medium and great radiation, are the best places for establishing the system. at last, regarding the obtained results, the application of the systems in every part of iran would be c possible.
