摘　　要：蒸发冷却降温具有高效、低能耗、无污染的特点,在工程项目中得到了广泛应用。目前蒸发冷却系统在临时建筑的应用效果研究较少,缺乏相关实验数据支撑。为降低施工临时建筑空调能耗,并防止分体式空调因环境温度过高引起压缩机高压保护而停机。采用了实验研究的方法,对比研究了在室外条件相近的条件下,建筑工程项目彩钢板房屋顶应用蒸发冷却系统对室内环境参数和分体式空调冷凝器环境温度的影响。结果显示:在夏季阳光照射下屋顶外表面温度可达50℃,在屋顶应用蒸发冷却系统后,屋顶内表面平均温度降低了5.2℃,分体式空调冷凝器环境温度降低了约3℃,室内平均温度降低了约3.8℃。经测算分析,每年制冷季可节省电量2570 kW·h,降低碳排放1493 kg。Evaporative cooling has the characteristics of high efficiency, low energy consumption and no pollution, which has been widely used in engineering projects. At present, there is little research on the application effect of evaporative cooling systems in temporary buildings, and there is lack of experimental data to support it. In order to reduce the temporary building air conditioning energy consumption and prevent split air-conditioning due to high ambient temperature caused by high-voltage compressor protection and shutdown, the method of experimental study is adopted in this paper. A comparative study was carried out under similar outdoor conditions, effect of evaporative cooling systems on indoor environmental parameters and ambient temperature of condenser of split air-conditioning in color steel roof of building project. The results show that the surface temperature of the roof can reach 50 °C in summer. After the evaporative cooling system was applied on the roof, the average temperature of the internal surface of the roof decreased by 5.2 °C. The ambient temperature of the condenser of the split air conditioner decreased by about 3 °C, and the average indoor temperature decreased by about 3.8 °C. Through calculation and analysis, the annual cooling season can save electricity 2570 kW·h and reduce carbon emissions 1493 kg.
