The analysis considered the effects of the storage tank volume connected to the solar panel and the hourly DHW consumption profile on the SF. As a result of the analysis, the energy of 928 GJ from the flat plate solar collector was stored into BTES system and 393 GJ of energy from BTES system was extracted during heating period, so that it was confirmed that the thermal efficiency of BTES system was 42% in 5th year. Thermal performances of the system in terms of the solar fraction (SF) was predicted using a TRNSYS model and the daylight saving time (DST) method. Numerical simulation was performed by modeling the solar thermal seasonal storage system consisting of flat plate solar collector, BTES system, short-term storage tank, boiler, heat exchanger, pump, controller. The TRNSYS was used to predict and analyze the dynamic performance of the solar thermal system. I have been using TRNSYS to model a solar thermal systems for more than 1 year. BTES (Borehole Thermal Energy Storage) was considered as a seasonal storage, which is relatively economical. TRNSYS is a software for dynamic simulation of renewable energy systems. This paper investigates the integration of solar thermal and photovoltaic (PV) energy. And, the heating load of the glass greenhouse selected was 576 GJ. powering a direct contact membrane distillation: TRNSYS simulation. For this study, the gardening 16th zucchini greenhouse of Jeollanam-do agricultural research & extension services was selected. The heating performance of a solar thermal seasonal storage system applied to a glass greenhouse was analyzed numerically. ![]()
