摘要
针对《全国民用建筑工程设计技术措施》暖通空调.动力篇(2009年版)中以"最湿月平均含湿量"作为气候分区判断依据一问题,探讨了含湿量(绝对湿度)和相对湿度概念的不同,指出含湿量是空气加湿或减湿的程度,而相对湿度表示的是空气接近饱和的程度,并进一步分析了湿球温度是空气接近饱和程度的一种度量,是一个独立的空气状态参数。最后笔者通过一些气候分区的举例,进一步说明了湿球温度这一参数在气候分区中的重要性。
Aiming at this＂the wet month average moisture content＂ as basis of climate division for the nationwide public construction engineering design technical measures in HVAC-power（2009）,discussion on the difference concept between the moisture content（absolute humidity） and the relative humidity,points out the moisture content is the degree of the air for humidification and dehumidification,while the relative humidity shows the extent of the air approaches saturation,analyzes the wet-bulb temperature is a measure about the air approaches saturation and an independent air state parameter.Finally the author gives some examples of climate division,further shows the importance of the parameter of wet-bulb temperature in climate division.
