焓湿图(i-d图)中各状态参数的关系

The Relationships among State Parameters in Psychometric Chart

文章主要涉及焓湿图中9个状态参数(温度t、含湿量d、相对湿度φ、焓i、空气水蒸气分压力Pq、湿球温度ts、露点温度tl、空气饱和水蒸气分压力Pq,b和空气饱和水蒸气含湿量db)及对各状态参数之间关系的理解,作者用图示的方法说明这些状态参数之间的关系。

This paper mainly discusses nine state parameters in psychometric chart, i.e. temperature t humidity ratio d, relative humidity φ. enthalpy i, the partial pressure of the water vapor in the air Pq, wet-bulb temperature t. dew-polnt temperature t1, the partial pressure of the water vapor in the saturated air Pq,b and moisture content in saturated air db. The relationships among these parameters are illustrated by charts.
