合肥地区室外空气焓值分布特征研究

Study on Distribution Characteristics of Outdoor Air Enthalpy in Hefei Area

基于2006年~2015年合肥地区室外空气气象参数,构建数学模型用于计算室外日平均空气焓值,研究室外空气焓值分布规律,并统计满足人体Ⅰ级、Ⅱ级热舒适范围焓频值。冬、夏季满足人体Ⅰ级、Ⅱ级热舒适范围焓频值占全年天数比例较小,仅自然通风无法满足室内舒适要求,需辅助人工手段加以调节;过渡季节满足热舒适要求焓频值较大,有较大的自然通风潜力,仅单一调节温、湿度可满足室内舒适要求。合肥地区热舒适Ⅰ级以调温为主,Ⅱ级以调湿为主。

Based on the outdoor air meteorological parameters in Hefei from 2006 to 2015, the daily average air enthalpy values were calculated and the enthalpy frequency of the thermal comfort ranges of human body Ⅰ and Ⅱ were calculated. In the winter or summer, the enthalpy frequency of thermal comfort range of human body Ⅰ and Ⅱ is smaller than that of the whole year. Only natural ventilation does not meet the indoor comfort requirement. Artificial means are used to meet indoor comfort requirement. In the transitional season, the enthalpy frequency is larger and the natural ventilation potential is higher, and only a single temperature and humidity can be adjusted to meet the requirements of indoor comfort. Temperature is regulated mainly to meet the requirements of the human body thermal comfort Ⅰ level. Humidity is regulated mainly to meet the requirements of the human body thermal comfort Ⅱ level.
