Abstract

In this paper, experimental research has been conducted intended for using Phase Change Materials (PCM) by incorporating it with the building layers walls. The effect of involving PCM volume ratio and orientation on the thermal efficiency and thermal comfort was experimentally studied. Two identical rooms models have been constructed. The first model was used as a standard room as a reference one without using PCM and the second model has the PCM layers and used for all experimental testing works. Both rooms are installed at National Research Center, NRC, Giza, 30.08° N latitude, Egypt. The PCM used in this experimental work was paraffin wax having a melting point of 29 °C. Many cases have been studied based on the south wall, east wall and west wall respectively. It is found that using PCM caused a considerable reduction in the indoor air temperature and consequently reduction in the cooling load that minimizes the building energy consumed. It is concluded that the Percentage of the cooling load reduction of the zone by using PCM and according to cases and for peak hour in day was 19.2 % with PCM for East, West and South walls together, followed by 16.8 % for South wall only, followed by 12.7 % with West wall only and followed by 10.5 % for East wall only. It is found that the best case in cooling load reduction of the room for peak hours of PCM for South, West and East walls together by 19.2 %. The experimental results of the present study were validated with the corresponding experimental study of Mushtaq 2018 with a considerable agreement between the daily cooling load reduction per space volume and the cooling load reduction ratio. It is known that the cooling load reduction ratio is referred to the energy-saving which proved that using PCM in the building will contribute to energy saving in residential building
