深埋防护工程区划及热舒适模型

为了更好地指导深埋防护的热工设计,通过对影响防护工程热工和热舒适特性相关因素的分析,计算了全国151个主要城市的热工分区指标值,建立了寒冷、干燥、潮湿、热湿4个深埋防护工程的热工区划;基于热工分区和热舒适适应性模型理论,提出了适用于防护工程的热舒适模型。基于热舒适模型, 减小了设计温度与室外空气温度、地温的差值,有利于降低采暖和制冷能耗。通过对典型城市的应用分析表明,采用热舒适模型,新风能耗节能率为6%,围护结构节能率在寒冷地区为20%,具有较好的节能效果。

Thermal division and comfort model for protective engineering

To coach thermal design, the factors impacting the thermal characteristics and comfort were analyzed, and the indictors of 151 major cities were calculated. Our country was classified as four design divisions: cold region,dry region,moist region,heat and moist region. Based on the thermal adaptation theory and thermal divisions, the thermal comfort model for the protective engineering was attained. The energy consumption of heat and cooling could be reduced by using the thermal adaptation model, which lessens the difference between the design temperature and the outdoor temperature, and the underground temperature. According to the analysis of applications in typical cities, the result show that the energy saving rate of fresh air was 6%, that the inclosure wall was 20% in cold region,and that its energy saving effect was more evident.
