THERMAL PERFORMANCE MODEL OF SOLAR COLLECTORS WITH INTEGRATED PCM-TES
Abstract
In the current global context where we talk about the depletion of conventional fuel resources and their impact on the environment, we find that it is necessary to integrate renewable energy sources/resources in new constructions, but also adapt existing constructions in order to reduce energy consumption. This article presents a system with solar thermal collectors combined with PCM phase change materials. During operation, some of that thermal energy may be diverted to a storage system where it is maintained for later use. The storage system has a solid organic PCM material. This is a model that is based on a general trend of performance with the help of the flat solar collector combined with a PCM storage medium used at the bottom. At the same time, the heat exchanger coil is used to increase performance. The model is based on static performance and certain general parameters, surface and design limits are considered known. Therefore, the method of integrating the PCM material with FPC (Flat Plate Collectors) is based on thermal performance, so the characteristic parameters can be deduced, namely temperatures, energy efficiency, heat transfer coefficients, energy equations. Thus a more efficient solar collector system (FPC) can successfully replace convection systems by helping to reduce energy consumption in buildings.
