摘　　要：岗亭建筑数量多、分布广,其夏季热环境问题突出,但关注较少。本文以西安市岗亭建筑为研究对象,在夏季对典型岗亭的进行了现场测试。结果表明:在夏季,西安的岗亭建筑若不开启空调,室内空气温度明显高于室外,白天室内出现高温且持续时间长。开启空调的岗亭建筑单位面积供冷耗电量高,是常规办公建筑的3倍。采取遮阳、玻璃贴膜、安装保温棉的被动式措施可改善岗亭室内的热环境。其中,玻璃隔热膜改善效果较好,测试期间能够使日均值降低1.2℃,冷负荷下降9.4%。安装空调的岗亭应结合被动式措施,改善室内热环境的同时降低供冷耗电量。There are a large number of sentry boxes widely distributed,with prominent issues regarding their summer thermal environment,yet receiving relatively little attention.This paper took the sentry boxes in Xi'an as a research object,conducting on-site tests on typical sentry boxes in summer.The results indicated that in summer,if air conditioning is not used in sentry boxes in Xi'an,the air temperature is significantly higher indoors than outdoors,with prolonged high-temperature periods during the day.Sentry boxes with air conditioning have high energy consumption for cooling per unit area,three times that of conventional office buildings.Passive measures such as shading,applying window films,and installing thermal insulation can improve the indoor thermal environment of sentry boxes.Among these,the effect of glass heat-insulating film is particularly good,with tests showing an average daily temperature decrease of 1.2℃anda9.4%reductionincoolingloads.Air-conditioned sentry boxes should be combined with passive measures to improve the indoor thermal environment while reducing energy consumption for cooling.
