many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

A thermal energy storage (TES) equipment utilizing phase change material (PCM) was designed and built. The PCM is sealed inside metal tubes and exchanges heat with process fluid flowing outside. The storage capacity characteristics of the system was analyzed based on date covering the inlet and outlet temperatures of the process fluid, volumetric flow rate of the process fluid, and temperature ...

Abstract Energy crisis is a major challenge in the current world. Latent heat thermal energy storage (LHTES) systems are known as equipment with promising performance by which thermal energy can be recovered. In the present study a comprehensive theoretical and experimental investigation is performed on a LHTES system containing PEG1000 as phase change material (PCM). Discussed topics can be ca...

The synergistic combination of sorbitol-based organogelators with polyolefins allows a fast and easy preparation porous support structures for immobilised phase change materials (PCM) in one step.

Phase change materials (PCM) are expected to be indoor thermal environmental control in a residential house. In this paper, experiment for effect of introducing PCM was conducted test chamber with wall. The relationship between difference melting point and environment were analyzed by CFD. As result, the temperature fluctuation small due different pasting positions PCM. It suggested that energy...

Appropriate measures have been taken to reduce energy requirements for cold chain applications. Thermal storage is an accepted method the need electrical after harvesting fresh horticultural produce. The use of phase change materials (PCM) in postharvest storage, outside a temperature-controlled environment, extends shelf life and keeps food at ideal temperature. This review focuses on various ...

We designed a two-step Pickering emulsification procedure to create nano-encapsulated phase changing materials (NEPCMs) using a method whose simplicity and low energy consumption suggest promise for scale-up and mass production. Surface-modified amphiphilic zirconium phosphate (ZrP) platelets were fabricated as the Pickering emulsifiers, nonadecane was chosen as the core phase change material (...

Energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. Recently, using phase change materials (PCM) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. In the present research, the effects of the ...

In internal curing, pre-wetted lightweight aggregates (LWA) serve as internal reservoirs to supply the extra water needed by the cementitious and pozzolanic components of the concrete during their hydration processes. Due to their porous nature and reasonably high absorption capacity, the LWA can also be filled with other materials, such as phase change materials (PCMs). In this paper, three po...
