关于夏季空气调节室外空气计算参数的讨论
Discussion on outdoor air design conditions for summer air conditioning
摘要：
根据我国室外气象数据，比较了由历年平均不保证50 h干、湿球温度计算得到的含湿量与根据气象数据历年平均不保证50 h统计得到的含湿量的差异。考虑到室外气候条件对建筑热环境和不同设备空气热湿处理过程的影响，建议在空调设计中根据影响因素不同选取相应的室外空气设计参数。采用国家气象局1971—2003年的气象数据，得到全国31个主要城市分别以空气干、湿球温度和露点温度为主的3种设计指标。
Abstract：
According to the outdoor meteorological data of China, compares the difference between the humidity ratio calculated based on annual dry-bulb and wet-bulb temperature under the condition of not guaranteeing 50 hours everage per year and the annual statistical humidity ratio under the condition of not guaranteeing 50 hours everage per year. Comprehensively considering the influence of outdoor conditions on indoor thermal environment and the air handling process of different equipment, suggests that corresponding outdoor design conditions should be selected according to different influence factors in air conditioning design. Using the meteorological data from 1971 to 2003 by the China Meteorological Bureau, gains three design indices of 31 China’s main cities in which dry-bulb, wet-bulb and dew-point temperature are respectively used as a key factor.
