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 outdoor air meteorological parameters in Hefei area from 2006 to 2015, a mathematical model was constructed to calculate the daily average outdoor air enthalpy, the outdoor air enthalpy distribution was studied, and the enthalpy values of thermal comfort range of human body in grade I and II were calculated. In winter and summer, the enthalpy value of the thermal comfort range of the human body in class I and II is smaller than that in the whole year. Only the natural ventilation can not meet the indoor comfort requirements and is assisted by artificial means; the enthalpy value Large, with greater potential for natural ventilation, only a single regulation of temperature and humidity to meet the indoor comfort requirements. Hefei area thermal comfort grade I to temperature-based, grade II to humidity-based.
