Abstract

Energy consumption in conventional domestic housing in Oman is quite high due to cost intensive mechanical air conditioning systems. For the climate conditions in Oman, it is expected that energy conservation using smart passive cool roof will be valuable and significant. This paper presents the thermal assessment and energy efficiency of a novel forced convective evaporative cooling system with radiation reflector. The results revealed that the proposed smart passive cool system can reduce the indoor air temperature of the building models, with highest reduction in the room and roof surface temperature of 13.07 °C (36.7%) and 66.42 °C (75.7%) respectively. This is due to its ability to inhibit solar radiation and dissipate heat by evaporation, forced convection due to the dynamic behavior of air in the air ventilation between primary and secondary roofs, and nocturnal radiation. The research has conclusively demonstrated that the smart passive cool roof system presented significantly lower the heat fluxes through the roofs and can be applied to residential and commercial buildings for energy consrvation

智能被动冷却系统热评估的实验研究

由于成本密集的机械空调系统，阿曼传统住宅的能源消耗相当高。对于阿曼的气候条件，预计使用智能被动式冷屋顶的节能将是有价值的和重要的。本文介绍了一种新型带辐射反射器的强制对流蒸发冷却系统的热评估和能量效率。结果表明，智能被动式制冷系统可降低建筑模型的室内温度，室内和屋顶表面温度的最高降幅分别为13.07°C(36.7%)和66.42°C(75.7%)。这是由于它能够抑制太阳辐射并通过蒸发消散热量，由于主要和次要屋顶之间的空气通风中的空气动态行为而强制对流，以及夜间辐射。研究结果表明，智能被动式屋面冷系统显著降低了屋面热通量，可应用于住宅和商业建筑的节能
