wet-bulb

The chamber and the flask appear to have been inside a constant temperature bath (B); the air temperature inside the chamber C was measured by a thermometer (D) and the humidity by a wet-bulb thermocouple (W).

Ever the experimenter, he created his own wet-bulb thermometer to measure humidity, though a “Mr. Leslie” independently came up with the same technique and developed it into the widely used instrument.

Hutton, James 2009

Crossflow designs will have much greater water splash out with high winds, especially when fans are off at low-load or low wet-bulb situations.

As the device is spun in the air, evaporation of the water from the wet-bulb thermometer occurs, cooling it.

Atmospheric humidity 2006

After a few minutes of twirling, the temperatures of the wet-bulb and dry-bulb thermometers are determined, a value called the wet-bulb depression is calculated (dry-bulb minus wet-bulb temperature), and a psychrometric table is used to find the corresponding relative humidity from the dry-bulb temperature and wet-bulb depression.

One of the thermometers, called the wet-bulb thermometer, has small cloth hood (wick) that is pulled over the reservoir bulb.

If the air is saturated, the wet-bulb and dry-bulb thermometers would have the same temperature because no evaporation can occur.

The pond water’s average temperature follows the average ambient wet-bulb temperature (about 1°C above it) with swings depending on the pond’s depth.

In direct evaporative cooling, the air is humidified while its dry-bulb temperature drops and the wet-bulb temperature remains constant.

6. Energy efficient building design 1995

Direct evaporative cooling is a well-established technology and can be applied wherever the ambient average summer wet-bulb temperature is below approximately 18°C.
