The more familiar air temperature is known as the "dry-bulb" temperature; wetbulb temperatures can be used along with the dry bulb temperature to calculate humidity.
“干球温度”是更为常见的空气温度计量法，它同“湿球温度”一起，能够用来测量湿度。

It was shown that wetbulbtemperature and altitude could do effect on the air density which influence the performance of room air conditioner according with the other equation.
According to the criteria on testing air cooling equipments by means of air enthalpy difference method, air humidity is often obtained in the way of sampling wetbulbtemperature.
