Wet-bulb temperature is measured using a wet-bulb thermometer, which is an
ordinary liquid-in glass thermometer whose bulb is enclosed by a wick moistened
with water, often called a sling psychrometer. The psychrometer is whirled around
in the air. If the air is not saturated (100% relative humidity), the water in the wick
evaporates and the water temperature falls below the
dry-bulb
temperature. Figure
2 shows the
wet-bulb
temperature lines on the psychometric chart.
9.0 How evaporative cooling works:
In order to have an understanding of how the COOL-SPACE ® portable evaporative
cooler works a basic understanding of psychrometrics is necessary. Psychrometrics is the
branch of thermodynamics devoted to the study of air and water vapor mixtures. The
psychrometric chart is a graphical representation of properties of moist air. To illustrate
how the COOL-SPACE ® unit operates, some of the relevant properties are described in
this section followed by a sample application.

Dry-bulb temperature is measured with an ordinary
thermometer. Dry-bulb temperature lines on the
psychrometric chart are the vertical lines shown in
