湿空气含湿量的测量方法及其表达式的研究与应用
|
摘要
根据饱和水蒸气分压力的经验公式,分析得出了较为适用的湿空气含湿量的表达式,改变了传统的查询湿空气焓湿图或性质表得到含湿量的方法,为除湿空调机组进、出风含湿量的测量与直接显示提供了依据,并可实现出风含湿量的精确控制。
Based on the empirical formulas of saturated vapor partial pressure,the suitable formulas of humidity ratio in moist air are obtained,which changes the traditional method of obtaining humidity ratio by inquiring the humidity enthalpy diagram or property table of moist air,a basis for the measurement and direct display of humidity ratio in the inlet and outlet air of dehumidifying air units is provided,precise control of the humidity ratio of air outlet can be realized.
