湿空气密度的快速准确测算方法

从湿空气的物理参数关系理论出发,提出了使用精密气压计和干湿球温度计测算湿空气密度的快速简便方法,推导出了求解湿空气的相对湿度及饱和水蒸气分压力的数学模型。对工程上常用的湿球温度沿等焓线近似法与精确法进行了对比,验证了工程近似法的可用性。对于空气调节中常用的密度公式也进行了分析对比。

Rapid and Accurate Calculation Method of Wet Air Density

This paper put forward a simple and quick calculation method for wet air by precision barometer and psychrometer according to the relation theory of physical parameters of wet air, and derived a mathematical model for calculating the relative humidity of wet air and partial pressure of saturated vapor. A program for calculating the state parameters of wet air was prepared. Comparison was made to the isenthalp approximate method commonly used in engineering with the accuracy method, the feasibility of the engineering approximate method was demonstrated and comparison was also made for the density formula commonly used in air conditioning.
