TL;DR: In this article, the authors examined the significance of using phase change material (PCM) in the construction works for conservation of energy and showed that using PCMs can help in enhancing thermal performance of buildings as these have the advantage of high storage density with small temperature swing.
Abstract: This work examines the significance of using phase change material (PCM) in the construction works for conservation of energy. The objective of using PCMs is that the materials help in enhancing thermal performance of buildings as these have the advantage of high storage density with small temperature swing. Among various types of PCM, rice bran distilled fatty acid – grade A (RBDFA), which is a non-paraffin type was selected considering its thermal and physical parameters, particularly its melting point that falls between human comfort temperature range. Two types of investigations, numerical and experimental, were followed in the methodology to identify the thermal performance of building during PCM usage. The results indicated that inclusion of RBDFA in construction gives positive effect in maintaining less temperature variation at indoor.Practical application: Phase change materials are substances capable of storing or releasing thermal energy as latent heat. Phase change material has wide application...

TL;DR: In this article, the authors demonstrate the significance of phase change material (PCM) in the construction of working sheds and product storage magazines in fireworks industries to maintain less temperature variation by passive cooling.
Abstract: This work demonstrates the significance of Phase Change Material (PCM) in the construction of working sheds and product storage magazines in fireworks industries to maintain less temperature variation by passive cooling. The inorganic PCM, namely Calcium Chloride Hexahydrate (CCH) is selected in this study. First, the performance of two models with inbuilt CCH was analysed, using computational fluid dynamics. A significant change in the variation of inner wall temperature was observed, particularly during the working hours. This is mainly due to passive cooling, where the heat transfer from the surroundings to the room is partially used for the phase change from solid to liquid. The experiment was carried out by constructing two models, one with PCM packed in hollow brick walls and roof, and the other one as a conventional construction. The experimental results show that the temperature of the room got significantly reduced up to 7 °C. The experimental analysis results had good agreement with the numerical analysis results, and this reveals the advantage of the PCM in the fireworks industry construction.

TL;DR: In this paper, a phase change material (PCM) was used as the heat-storing material in a conventional solar dryer to reduce the absolute drying time of food products.
Abstract: Organic paraffin wax, a phase change material (PCM), was used as the heat-storing material in this study. The novelty of this work is the application of a PCM-packed floor in a conventional solar dryer to reduce the absolute drying time of crops. A PCM-packed solar dryer prototype model was constructed with an extendable drying chamber for easy loading, unloading, tilting, and shuffling the food products. The innovative drying setup was constructed to reduce human efforts and improve the drying in the preservation of food products. Four crops (guava, banana, coconut, ladies’ finger) were chosen for the experimental testing of the fabricated model. The samples were tested using the solar dryer with and without the PCM. The outcomes revealed that PCM usage helped retain the heat longer than the test without PCM. The drying time of all four crops was decreased by about 3-4 hours by installing the PCM, thereby reducing the crop drying time per day. The peak temperature attained by the crops in the presence of PCM had considerably improved, i.e., 7.81 % for guava, 4.55 % for banana, 3.125 % for coconut, and 8.33 % for ladies’ finger. The outcomes revealed that the colour, fragrance, and quality of the solar-dried products were better than the sun-dried products.

TL;DR: Research into unique polymeric systems provides a novel means of encapsulation or creating polymeric cross-linked matrices to prevent leakage and improve mechanical robustness and these two areas of polymer research in architecture represent key advancements for construction materials aimed toward energy savings and energy-related emissions control.
Abstract: In an effort to slow the progress of climate change, the current scientific community has focused on the reduction of greenhouse gases in order to limit the global average temperature inflation to less than 2 °C. The improvement of thermally controlled construction materials can potentially result in lower energy homes/reduced emissions, and lowering the thermal conductivity of insulation materials improves home energy efficiency. Nanoporous insulation foams impart a drastic decrease in thermal conductivity but many polymer properties must be assessed to produce these materials. Passive phase-change materials also represent another key energy-saving device to control heat flux within a living space. Research into unique polymeric systems provides a novel means of encapsulation or creating polymeric cross-linked matrices to prevent leakage and improve mechanical robustness. These two areas of polymer research in architecture represent key advancements for construction materials aimed toward energy savings and energy-related emissions control.
