Numerical study on the thermal performance of building wall and roof incorporating phase change material panel for passive cooling application

A Study on a Novel Phase Change Material Panel Based on Tetradecanol/Lauric Acid/Expanded Perlite/Aluminium Powder for Building Heat Storage

“…The test cells were located in Tianjin, a middle latitude city in China, with a hot and dry summer but a cold winter [3]. The coloured steel sandwich insulation board is made of expandable polystyrene (EPS) foam board with two sides galvanized steel plate covered.…”

“…The heat storing/releasing characteristic of PCM has been used to enhance the thermal inertia of buildings and adjust the indoor temperature environment [3], and thus the building energy consumption can be reduced.…”

A comprehensive review on passive design approaches in green building rating tools

“…Roof insulation in a passive designed house [67], has been demonstrated to reduce both cooling and heating loads by slightly increasing the mean air temperature in winter and decreasing floor temperatures in summer. Roofs made of insulated sandwich board and integrated with PCM materials have proved to be efficient load reduction strategies for passive designed houses by Kong et al [63].…”

“…Furthermore, phase change materials (PCM) can be effective in increasing the storage mass of a lightweight building envelope. Thermophysical properties, outdoor climate conditions, indoor thermal comfort, energy saving potential and cost effects have been evaluated by many studies [63][64][65]. A comparatively high interior surface temperature drop of 4.14% and a yearly air conditioning energy saving of 2.9% were achieved in a thermal modeling investigation.…”

Experimental research on a novel energy efficiency roof coupled with PCM and cool materials

“…Hashem et al have studied the roof containing PCM and the results showed that this kind of roof can reduce the heat flux between 9% and 17.26% because of different variables in the experiment[18]. Zhou et al has also studied the application effect of phase change plasterboard and form-stable phase change wall and found that the inner temperature fluctuation can reduce 46% and 56% respectively[19].Kong et al have proved that the PCM used in the inner surface of the exterior wall showed better thermal performance than that of the outer surface numerically[20]. Ayca et al have investigated the effect of PCM used on a flat floor in Istanbul and found that a PCM thickness of 2 cm can meet the room requirements well…”
