“…We compared the heat storage capacity of 1 meter of PCM‐15 and OPC. The DSC result (Table ) of the PCM selected in this experiment showed an endothermic temperature range of 25°C to 38°C; therefore, the calculated temperature range was the same as 25°C to 38°C, and ∆T was 13°C.…”

“…Meanwhile, many researchers have suggested that the rational application of energy storage materials can functionally reduce the room temperature swings in the building, thus leading to an improvement of energy utilization efficiency and a reduce of the energy consumption. Phase change materials (PCMs) which combine sensible heat storage and latent heat storage capacity had been widely concerned and investigated due to its advantages such as high energy storage density, small change in volume, keeping constant temperature during the thermal storage, and release recycling processes …”

Summary In this work, a novel Na2SO4·10H2O/fly ash shape‐stabilized phase change material mortar (PCM mortar) was prepared for building energy efficiency, in the context of energy conservation and environmental protection. The working, mechanical, and thermal properties of this proposed PCM mortar were investigated. The experiment results showed that the incorporation of PCMs greatly increased the thermal inertia of the mortar, while corresponding compressive strength was little affected. Specifically, when the blending amount of PCMs reached 15%, the thermal storage capacity of mortar sample (PCM‐15) was 6.18 × 104 kJ/m3, which is 2.4 times of that for mortar sample without PCM (OPC) evaluated by theoretical calculations, while the corresponding compressive strength of mortar sample (PCM‐15) still remained above 31 MPa. Furthermore, the effects of PCM mortar on thermal comfort and energy use of buildings were studied by using experiment and simulation methods, respectively. The control experiments showed that PCM mortar can effectively alleviate the influence of outdoor temperature on indoor temperature compared with OPC. Temperature difference between PCM‐15 and OPC board can reach 4.6°C (inner surface) and 8.6°C (outer surface), respectively. Meanwhile, temperature difference of internal space reached 1.2°C. The simulation results showed that the energy consumption per unit building area was reduced by 4.4 and 18.7 kg/m2 in Guangzhou and Harbin, respectively, with PCM mortar as the envelope structure. Hence, the proposed PCM mortar showed significant thermal and mechanical properties and had broad application prospects in regulating indoor temperature and constructing energy‐efficient buildings.

Summary Phase change materials (PCMs) have great potentials to be used in modern building materials to stabilize indoor temperature fluctuations for improving thermal comfort. This paper presents a comprehensive review on the use of PCMs in buildings to improve thermal comfort without increasing energy consumption. Concise discussions of the experimental and computational works reported in literature are presented. A special focus of this review is devoted to discussing different analysis methods and models used to test, characterize, and measure the performance of PCMs in modern building applications under different conditions. This detailed review also highlights the special attention given to organic PCMs, such as paraffin, due to their favorable properties, such as low price, chemical stability, non‐corrosiveness, and high latent heat of fusion. The review shows the scarcity of literature reporting the use of eutectic PCMs in building applications, despite their high volumetric storage density.

Abstract.The study was carried out to the determine performance of passive wall cooling panels by using Phase Change Materials as a cooling agent. This passive cooling system used cooling agent as natural energy storage without using any HVAC system. Eight full scale passive wall cooling panels were developed with the size 1500 mm (L) x 500 mm (W) x 100 mm (T). The cooling agent such as glycerine were filled in the tube with horizontal and vertical arrangement. The passive wall cooling panels were casting by using foamed concrete with density between 1200 kg/m 3 -1500 kg/m 3 . The passive wall cooling panels were tested in a small house and the differences of indoor and outdoor temperature was recorded. Passive wall cooling panels with glycerine as cooling agent in vertical arrangement showed the best performance with dropped of indoor air temperature within 3°C compared to outdoor air temperature. The lowest indoor air temperature recorded was 25°C from passive wall cooling panels with glycerine in vertical arrangement. From this study, the passive wall cooling system could be applied as it was environmental friendly and less maintenance.
