The primary purpose of this thesis is the study of phase change materials (PCMs) on both a theoretical and experimental level.
In the first part, following the highlighting of the need for new energy saving technologies, based on phase change materials, a theoretical overview is presented. Subsequently, a thorough analysis is provided concerning their properties, applications (on a broad scale, but mainly in building constructions) and their classification.
In the second part, the illustration and experimental study of the installation takes place. The installation consists of a chamber wall -externally insulated- containing the PCMs, the charging of which, is achieved by hot water circulating through the wall. Specifically, the hot water exits the solar collector system, charges the PCMs and returns to the collector for reheating. The absence of a heat storage tank is due to the presence of PCMs, which serve exactly this purpose. After all, the pursuit of this experimental study is the maximization of the capacity of stored heat in the PCMs, facilitating its release when required. Specifically, the aim is to maximize the exploitation coefficient of the PCM by modifying the parameters regarding the installation.
Finally, the demonstration and evaluation of the results is provided, as well as a comparison between the energy saving system with PCMs and the equivalent system with concrete. Additionally, suggestions are made for further investigation and potential topics for other theses. |
