By Zhao Kang , Liu Xiaohua, Zhang Tao andJiangYi Abstract According to the outdoor eteorological data of China, co pares the difference between the hu idity ratio calculated based on annual drybulb and wetbulb te perature under the condition of not guaranteeing 50 hours everage per year and the annual statistical hu idity ratio under the condition of not guaranteeing 50 hours everage per year. Co prehensively considering the influence of outdoor conditions on indoor ther al environ ent and the air handling process of different equip ent, suggests that corresponding outdoor design conditions should be selected according to different influence factors in air conditioning design. Using the eteorological data fro 1971 to 2003 by the China Meteorological Bureau, gains three design indices of 31 Chinas ain cities in which drybulb, wetbulb and dewpoint te perature are respectively used as a key factor. Keywords eteorological data, drybulb te perature, wetbulb te perature, dewpoint te perature ! Tsinghua University, Beijing, China ∃ 0 20 , ,
