用PMV-PPD指标体系研究地下空间空气温度标准

Research on the air temperature standard in underground space with the PMV-PPD Index System

地温是影响地下工程室内热舒适指标的重要因素。研究发现,纬度和海拔高度对地温有很大影响。利用 Fanger 人体热舒适方程和 PMV-PPD 指标体系研究发现,壁面温度高的南方地区,地下工程室内设计温度应比壁面温度低的北方地区取值低。将全国分为三个空调区,并给出了相应的设计参数。

The soil tempeature is an important factor influencing the indoor thermal comfort in underground space.Finds that latitude and height above sea level have a significant impact on soil temperature.By an analysis using Fanger’s equation and the PMV-PPD Index System,suggests that the design indoor temperature in the south region with higher wall surface temperature should be lower than that in the north region with lower wall surface temperature. Accordingly divides the whole country into three air-conditioning regions and presents the corresponding design data.
