Evaporative cooling uses the power of evaporation to cool the air. Hot and dry air from outside is drawn through cooling pads soaked in water. The water evaporates as the air passes through the pads. This heat absorbs, which reduces the temperature. The cool air is then pushed through a network of conduits by a fan.
Evaporative cooling works best when all cooling pads are fully saturated. The fan and motor must be sized to provide the right airflow to the area. Evaporative cooling works by heating the air to convert liquid water to vapor.
Latent heat is the heat that evaporates water into water vapor. This heat cannot be detected by a thermometer. It is, for example, the heat of the hot pavement that evaporates water after a summer storm. The liquid water transforms into vapor when it absorbs heat from the surrounding environment. The molecular structure in the vapors contains the energy it absorbs.
This natural phenomenon of latent warmth is what makes evaporative cooling possible. The humidity and latent heat are increased by the moisture vapor that is introduced to the air. Evaporative coolers cool air through the evaporation water. Evaporative cooling is a different type of air conditioning system than traditional ones that use chemical vapor compression refrigeration cycles.
This natural phenomenon is called evaporative cool and evaporative chills. However, many terms are used interchangeably with the same meaning, including adiabatic cooling and swamp coolers.

Evaporative Cooling In Different Climates In American Schweizens
It’s important to review the principles of evaporative cooling to understand how cooling works in different climate zones. The temperature is reduced by the conversion of sensible heat to latent heat as water evaporates. Evaporative cooling requires two temperatures.
This is the temperature we think of as the temperature in the air. It can be measured using a thermometer that has been exposed to the air stream. The temperature in the United States is usually measured in degrees Fahrenheit .
Wet-Bulb Temperature
This is the temperature at which water vapor can be dissolved in the air. The wet-bulb temperature, which is the temperature at which water evaporates into the air, can be used to measure the potential for evaporative cool. You can calculate relative humidity by comparing the dry and wet bulb temperatures.
When the relative humidity drops below 100 percent, the air absorbs water and evaporates. A given volume of air can contain a certain amount of water vapor. The degree of absorption depends on the temperature at which it was heated and how much vapor it has already.
Relative humidity refers to how much water there is in the air relative to its capacity. When air cannot hold more water, it is considered saturated.
Imagine air as a sponge. If it held half the amount of water it could hold, it would be 50% saturated. Air would have a relative humidity of 50%.
Water must be transformed from liquid to vapor using energy. This energy comes from the air. The heat energy is converted to sensible heat by the air entering an evaporative cooler. This causes the coolant to drop in the dry-bulb temperature.
