“…Both the arrangements have an air cavity in proximity for natural ventilation. This highlights that placement of the PCM layer can be an important consideration while integrating PCM into buildings, depending on whether heat needs to be retained (cold climate) or removed (hot climate) [20,28]. After 16:00, the temperature difference started decreasing and became negative at 22:20, as shown in the window graph of Figure 6A,B.…”

“…A wall section as presented in Figure 1C evaluated in winter and summer conditions of the UK through numerical simulation reported that a 20 mm thick PCM layer along with a 20 mm air cavity can optimally achieve thermal comfort indoors [19]. A PCM vertical layer as shown in Figure 1D applied to south and west walls damped peak heat flux by 51% and 30%, delayed peak time by 6.3 h and 2.3 h, and reduced heat transfer by 27% and 4%, respectively [20]. A PCM based thermal energy storage (PCMTS) as shown in Figure 1E performed optimally when placed inwards next to the gypsum wallboard, yielding an 11% reduction in heat flux in Kansas, USA [21].…”

“…A PCM configuration as shown in Figure 1F reported a temperature drop of 7 °C and a time lag of 6 h at maximum in the typical weather conditions of Tlemcen (western Algeria) [22]. Previously investigated configurations of integrating phase change materials (PCMs) in wall sections, namely: (A) a thin layer of PCM between two layers of insulation tested in Quebec City, Canada [17]; (B) two layers of PCM impregnated wallboards applied as an exterior and an interior layer with thick insulation in-between, tested in a continental climate [18]; (C) a PCM and an air cavity layer contained between two concrete blocks, tested in the cold climate of South East England, UK [19]; (D) a PCM layer installed near the internal wallboard having multi-layers of insulation boards and sheathing towards the exterior, tested in Kansas, USA [20]; (E) various configurations of gypsum wallboard, cardboard, PCM layer, insulation layer and OSB layer, tested in Kansas, USA [21]; and (F) a simple wall assembly of brick and concrete, applying a PCM layer in-between, tested in West Algeria [22].

In the current study, a phase change material (PCM) contained in an insulated concrete block is tested in extremely hot weather in the United Arab Emirates (UAE) to evaluate its cooling performance. An insulated chamber is constructed behind the block containing PCM to mimic a scaled down indoor space. The effect of placement of the PCM layer on heat gain indoors is studied at two locations: adjacent to the outer as well as the inner concrete layer. The inclusion of PCM reduced heat gain through concrete blocks compared to blocks without PCM, yielding a drop in cooling load indoors. The placement of PCM and insulation layers adjacent to indoors exhibited better cooling performance compared to that adjacent to the outdoors. In the best case, a temperature drop of 8.5% and a time lag of 2.6 h are achieved in peak indoor temperature, rendering a reduction of 44% in the heat gain. In the tested hot climate, the higher ambient temperature and the lower wind speed hampered heat dissipation and PCM re-solidification by natural ventilation. The findings recommend employing a mechanical ventilation in hot climates to enhance regeneration of the PCM to solid state for its optimal performance.

In the past several decades, many literatures have emerged on the topic of phase change material and latent heat storage techniques used in building. Accordingly, it is essential to review previous work to know about phase change material application in building better. This article presents a review on phase change material application situations in building, and several aspects are discussed: phase change material major applications in building, phase change material application areas, phase change material application types, phase change material thermal-physical properties, and phase change material application effects. The results of this research show that phase change material application areas are mainly concentrated into four parts of north latitude from 25°to 60°and south latitude from 25°to 40°. No matter in which region, the use of paraffin is the broadest (the maximum use frequency is up to 87.5%). For organic phase change material, the melting temperature and the heat of fusion vary from 19°C to 29°C and from 120 kJ/kg to 280 kJ/kg, respectively. The best phase change material application effect found is a reduction of 4.2°C for air temperature in room. This study has important and directive significance for the practical application of phase change material in building.

“…Recently, the use of phase-change materials (PCMs) in building components, such as walls [1][2][3], roofs [4][5][6][7][8][9][10], windows [11][12][13], and floors [14][15][16][17], has grown. PCMs function as thermal storage materials that can absorb or release heat during liquefaction or solidification at their phase-change temperatures.…”

Abstract:We assessed the usefulness of phase-change material (PCM)-based thermal plates fabricated from wood-plastic composites (WPCs) in mitigating the urban heat island effect. The thermal performance of plates containing PCMs with two different melting temperatures and with two different albedo levels was evaluated. The results showed that the PCM with a melting temperature of 44 • C maintained lower surface and inner temperatures than the PCM with a melting temperature of 25 • C. Moreover, a higher surface albedo resulted in a lower surface temperature. However, the thermal performance of PCMs with different melting temperatures but the same surface albedo did not differ. Using PCM-based materials in roof finishing materials can reduce surface temperatures and improve thermal comfort.
