基于RWI-HDR的寒冷地区高速服务区室内热舒适研究

Research on Indoor Thermal Comfort of Expressway Service District in Cold Regions Based on RWI-HDR

通过对寒冷地区既有高速服务区室内舒适状况实测统计分析发现,TSV-TCV平均投票统计分析结果不能满足室内热舒适Ⅱ级要求,存在室内热扰多、冬季冷风渗透导致的温度过低现象。基于此,本文采用RWI与HDR指标对其室内热舒适状况进行评价,计算出不同工况下各区域所对应的RWI值与HDR值,并与实测值进行对比;建立适用于高速服务区建筑的RWI*与HDR*修正计算公式,并分析服务区人员的RWI*、HDR*值与室内温度对应关系,给出高速服务区室内环境热舒适范围;采用“走行路线实验法”对既有服务区热湿环境及舒适情况进行实测分析,以便对能源孤岛型建筑——高速服务区室内热舒适环境营造及节能措施提供参考。

Based on the actual measurement and statistical analysis of indoor comfort conditions in existing expressway service districts in cold regions,this paper found that the average voting statistical analysis results of TSV-TCV cannot meet the requirements of indoor thermal comfort class II,and there are excessive indoor heat disturbances and low temperature caused by cold air infiltration in winter.Based on the above,this paper used RWI and HDR indicators to evaluate its indoor thermal comfort,calculated the RWI value and HDR value corresponding to each district under different working conditions,and compared the difference between the measured value and the calculated value;the RWI∗and HDR∗correction calculation formula suitable for high-speed service district buildings was established.By analyzing the corresponding relationship between the RWI∗and HDR∗values of the service district personnel and the indoor temperature,the thermal comfort range of the indoor environment in the expressway service district was obtained.The thermal and humid environment and comfort conditions of the existing service area were measured and analyzed by′route experiment method′,with a view to providing some reference for the construction of indoor thermal comfort environment and energy-saving measures of energy island building(high-speed service area).
