To find the thermodynamic dry-bulb temperature the air is cooled by allowing water to evaporate into it until saturation is reached.
32.
This method can produce snow when the wet-bulb temperature of the air is as high as-1 �C ( 30.2 �F ).
33.
Meteorologists and others may use the term " isobaric wet-bulb temperature " to refer to the " thermodynamic wet-bulb temperature ".
34.
By subtracting the wet-bulb depression from the outside dry-bulb temperature, one can estimate the approximate air temperature leaving the evaporative cooler.
35.
Water-cooled chillers are normally more energy efficient than air-cooled chillers due to heat rejection to tower water at or near wet-bulb temperatures.
36.
Deep lake water cooling allows higher thermodynamic efficiency by using cold deep lake water, which is colder than the ambient wet bulb temperature.
37.
An actual wet-bulb thermometer reads a temperature that is slightly different from the thermodynamic wet-bulb temperature, but they are very close in value.
38.
It is important to consider that the ability for the exterior dry-bulb temperature to reach the wet-bulb temperature depends on the saturation efficiency.
39.
It is important to consider that the ability for the exterior dry-bulb temperature to reach the wet-bulb temperature depends on the saturation efficiency.
40.
Similar to the fogging system, the theoretical limit is the wet bulb temperature, but performance of the evaporative cooler is usually around 80 %.
