Heat Balance Model for PV/T Systems

Abstract

In paper, solar collectors and thermophotoelectric systems (PV/T) are considered, which are one of the most promising systems for instilling energy. Electricity, which is vibrated by photovoltaic panels, has a great potential, but there may be technological shortcomings, which do not give maximum efficiency. The meta of our research is the development of a universal model of heat exchange processes for optimizing the design features of PV/T systems at the stages of design and variability, which allows us to increase the term of service of such systems and increase their efficiency. The expanded model allows you to change more practical parameters for two coordinates of a flat collector, such as to change the consumption of thermal energy, thermal support of the absorber plate, heat exchange, operating temperature, etc. The results of the model investigations correlate with the experimental data. On the basis of the proposed model, a software product for the model-bath of PV/T systems was developed and tested on the experimental results of those ready-to-wear PV/T systems. In the course of carrying out the expansions, depending on the basic parameters, the heating of heat was removed when one segment of the collector was passed by approximately 1.5 °C. The designated in-crease in temperature is reached at a heat transfer rate of 0.6 m/s, which is to achieve a great rate. The most optimal will be the heating of heat when passing through the collector by 5 °C, which will allow to re-duce the speed of heat transfer to 0.2 m/s and significantly reduce the amount of electricity consumed by the pump. The variation of the expanded model allows to implement a wide range of optimization tasks at the stages of designing and optimizing solar collectors and PV/T systems, to take the optimal design parame-ters to achieve the greatest efficiency and minimum occupancy.
