Abstract:
Phase change material (PCM)-based ocean thermal energy harvesting is a relatively new method, which extracts the thermal energy from the temperature gradient in the ocean thermocline. Its basic idea is to utilize the temperature variation along the ocean water depth to cyclically freeze and melt a specific kind of PCM. The volume expansion, which happens in the melting process, is used to do useful work (e.g., drive a turbine generator), thereby converting a fraction of the absorbed thermal energy into mechanical energy or electrical energy. Compared to other ocean energy technologies (e.g., w

Abstract:
The major challenge associated with renewable-energy systems especially solar, is the supply intermittency. One effective solution is to incorporate thermal energy storage components utilizing phase change materials (PCMs). These materials have the potential to store large amounts of energy in relatively small volumes and within nearly an isothermal storage process. The primary drawback of today’s PCMs is that their low thermal conductivity values critically limit their energy storage applications. Also, this grossly reduces the melting/ solidification rates, thus making the system response ti

The present thesis project has been developed at the Department of Energy and Building Services Engineering of the Munich University of Applied Sciences. The thesis intends to present an overview of the use of phase change materials (PCM) for building insulation applications. In light of the high energy consumption in the building sector, the latent heat storage capacity of PCMs could be effectively used to provide passive thermal regulation of the indoor temperature as well as reduce energy consumption due to thermal regulation in buildings, which is often caused by high energy consuming solu

Abstract:
Because human population is growing at such a high rate, as well as the energy consumption per person, new ways of preserving and efficiently using available energy must be explored. Until new and abundant energy sources are found and means of their exploitation developed, research attention should be focused on finding ways of proper and safe use of what is nowadays available.In that sense, storage of thermal energy plays an important role both in heating and/or cooling applications, such as in residential or commercial buildings, and in industrial processes. Some of the technical solutions a

Abstract:
Salt hydrates have the potential to be used in heat storage as both phase-change materials (PCMs) and thermochemical materials (TCMs). These materials offer advantages over traditional heat storage methods due to their high energy densities. However, both domestic and industrial applications require thousands of thermal cycles and there are often many issues that need to be overcome before these materials can be used reliably for heat storage. One of the major issues with using salt hydrates as PCMs is incongruency - the formation of anhydrous phases during melting. In this research, the mecha

This report aims to study how the indoor climate in a conference room can be improved by the use of phase change material (PCM). The study includes an experiment where 40 kg of salt hydrate based PCM was placed within a conference room located in an office in the city of Uppsala, Sweden. The experiment resulted in a decrease in the peak temperature with respect to the internal heat gains in the conference room and a slower temperature increase with PCM implemented. The report concludes that PCM can improve the indoor climate in regard to its ability to limit the temperature fluctuation. The st

Abstract:
One of prospective procedures of absorbing thermal energy and releasing it during the required time is the application of phase change materials known as PCMs in building envelopes. High thermal energy storage (TES) materials has been a technology that effects the energy efficiency of a building by contributing in using onsite resources and reducing cooling or heating loads. Currently, many TES systems are emerging and contributing in building assemblies, however using an appropriate type of TES in a specific building and climate requires an in-depth knowledge of their properties.

Il presente lavoro di tesi mira a studiare l’utilizzo di aggregati artificiali (PLA) costituiti da aggregati leggeri (LWA) impregnati di materiali a cambiamento di fase (Phase-Change Materials, PCM) nei conglomerati bituminosi. L’obiettivo della tesi è quello di dimostrare che l’utilizzo di questi materiali nelle sovrastrutture stradali, grazie alla proprietà di cambiare fase (da solida a liquida e viceversa) in funzione della temperatura, induce una liberazione di calore. La conseguenza immediata dell’utilizzo di questi materiali è la ridotta necessità di manutenzione invernale, abbattendo i

Abstract:
While 3D stacked multi-processor technology offers the potential for significant computing advantages, these architectures also face the significant challenge of small, localized hotspots with very large heat fluxes due to the placement of asymmetric cores, heterogeneous devices and performance driven layouts. In this thesis, a new thermal management solution is introduced that seeks to maximize the performance of microprocessors with dynamically managed power profiles. To mitigate the non-uniformities in chip temperature profiles resulting from the dynamic power maps, solid-liquid phase chang

Molten salt, with (60% NaNO3 and 40% KNO3) has been used extensively for energy storage however; the low thermal conductivity and specific heat have limited its large implementation in solar applications. For that, molten salt with the additive of silver nanowires (AgNWs) was synthesized and characterized.
