A misting fan is an appliance people can use in order to cool themselves off during hot summer days or for any occasion that requires cooling.
As its name implies, the fan blows air much like a typical electric fan would. They have several similarities. Both have motors to help move the rotors which blow the air. Both are very cheap and cost effective when compared to air conditioners. And both of them do not consume a lot of electricity to operate.
Brief history of the misting fan
The combination of a fan and mist for controlling the environmental temperature saw application as early as the 1950s. Back then, it saw little commercial use and was actually used in helping cool off livestock.
A small time later, restaurants and other commercial establishments began using misting systems to help cool off their customers. Eventually, homeowners began to see the benefits of using a misting system in order to cool themselves off.
Since then, more and more people have begun to use misting systems in order to help cool themselves off.
The differences between the different fans
The biggest difference between misting fans and a typical run of the mill fan is the former’s use of evaporation in order to improve its cooling effect.
The human body perspires in order to cool itself off. The perspiration evaporates and is one of the natural ways that our body regulates temperature.
These new fans basically do the same thing. A pump is attached to the fan which sprinkles a bit of water into the air current being blown by the fan’s rotors. The gust blown by the rotors is a combination of air and a fine mist. The mist is what helps produce a breeze cooler than the ambient temperature.
The science behind the misting fan
The reason why these fans are different from conventional fans is that they, in a way, work similarly to air conditioners. Air conditioners use Freon gas in order to rapidly cool the air that it takes in and blows out. These new fans that incorporate mist into their technology provide cool air using the same principle, albeit using a different technology.
When the mist is blown, the tiny water particles evaporate due to the environment’s temperature. This is a result of the water’s ability to absorb the heat. The water absorbs the environments heat thereby making it cooler in the process.
The above explanation basically sums up the reason why these mist fans work better to cool off people than the usual electric fan.
The different kinds of misting systems
There are plenty of different misting systems to choose from. One of the first things people ought to consider is the pressure.
Misting systems come in three categories depending on their pressure. There are high, mid, and low pressure misting systems. The higher the pressure of the misting system, the more efficient it will be in cooling off the area.
A large expansive outdoor recreational area for example would benefit greatly from a high pressure misting system. This is typically a better solution than having several misting systems working together in unison.
A low pressure misting system is ideal for smaller areas or even for personal use. They are the cheapest of the lot, though that does not mean that they won’t work.
Variables which affect the misting system’s performance
Another thing that makes misting systems so different from other appliances which help regulate the environment’s temperature is that its efficiency is highly dependent on the humidity.
Misting systems work very similarly to humidifiers. The fan blows the fine mist of water into the air. If the air in a given area is not too humid, then the water evaporates. This in turn absorbs the heat allowing the misting system to work as a cooler.
Prospective buyers ought to keep in mind the humidity in their area before getting misting fans.
