HVAC and Humidity Control Part 1: Basics of Humidity

By |2020-05-14T22:47:14+00:00April 7th, 2020|Categories: Educational|

Relative Humidity (RH) describes the amount of water vapor held in the air at a specific temperature at any time, relative to the maximum amount of water vapor that air at that temperature could possibly hold. Air can hold more water vapor at higher temperatures than it can at lower temperatures.” Dew point is the temperature [...]
