The present study focuses on the design and fabrication of passive solar still system with phase change materials (PCM). In order to improve the distillate, PCMs (paraffin wax, stearic acid, and lauric acid) have been stored in a copper cylinder. The effects of basin water depth on total...

Thermal energy storage is essential in solar cooling applications due to intermittent and uncontrollable availability of solar energy. Various technologies are available for low temperature energy storage. In the present work, a solar-assisted ejector cooling system with latent heat cold storage...

This paper describes the theoretical rationale for a new low temperature phase-change desalination process, and six examples of applications to illustrate how this process can be engineered for sustainable desalination. In this process, brackish water is evaporated at near-ambient temperatures...

Exfoliated graphite nanoplatelets (xGnP) were applied to enhance the thermal conductivity of polyaniline (PANI) based form-stable phase change materials (PCMs). The xGnP was first dispersed in palmitic acid (PA) uniformly under the assistance of ultra-sonication. The xGnP/PA mixture was then...

This paper presents the results of an experimental study conducted on a multi-tank thermal storage for solar hot water heating applications. The purpose of the study was to investigate the thermal behaviour of the stratified tank system when subjected to constant temperature charging and...

Today, thermal energy storage (TES) is a key issue for concentrated solar power plants (CSPs). The available and mature technologies of TES do not mach all the actualised criteria for those properties. Alternative approaches have to be identified and developed to guaranty the expected extension...

The role of thermal energy storage (TES) in district energy (DE) system is assessed. The Friedrichshafen DE system is considered as a case study and exergy analysis is utilized. The TES is designed to complement and to increase the effectiveness of the solar panels included in the district...

Thermal storage with molten salt is considered to be an important subsystem for solar thermal power stations due to the fluctuation of sunshine over time. A molten salt thermal storage tank, in which the fluid is stratified in temperature with “hot” on the upper level and “cold” in the...

Thermal energy storage (TES) is regarded as among the most feasible environmentally friendly solutions for saving energy. R&D activities for heating and cooling of buildings lead to the development of various technology types.
