Examination the effectiveness of flow control in a solar system

Abstract: The present paper examines the benefits of the flow rate control compared with traditional on-off switch-control in case of solar water heating system. The optimal volumetric flow rate of the solar fluid depending on the radiation and the stored water temperature. This flow rate is realized with controlling the frequency of the pump by an ALTIVAR 31 frequency inverter. The paper presents and summarizes the calculated results based on measurement data obtained during the operation with these regulations.

“…Several analyses were conducted on hybrid PV/T system in theory, as well as the development of cogeneration components, like (PV/ thermal). In recent times, the PV/T solar energy utilization achieved a notable increase, due to the improvement in the performance of PV/T systems [1]. Said improvement consists of a combination of photovoltaic PV cells and solar thermal energy absorbing elements.…”
