Using a misting fan is a cheaper and greener way to cool down during the hot summer days. Unlike air conditioning units, a misting fan uses water to lower temperatures. For it to operate, it needs an electric and water source. Most misting fans come with storage tanks where the mister gets it water while some can be directly connected to a water hose for a continuous water supply. Because of its versatility, it can be used at different places.
Where can mist fans be used?
- Greenhouse – Not all plants can grow optimally at high temperatures. They also need to be cooled down. What better way to cool them down than through a misting fan. A mister not only provides a cooler temperature but it can also give the plants the additional moisture they need. The nozzle can be adjusted into a setting where the water is sprayed as droplets and not as a fine mist.
- Outdoor Games – Games like football are usually done outside under the blazing sun. The heat from the sun can lead to high temperatures which can be uncomfortable for both the athletes and spectators. One way to cool down during the game is to use misting fans. The fan directs the mist to various directions and pushes the mist even further. Because of this, wider areas can be cooled.
- Indoors – Since mister sprays water, many find it difficult to believe that they can be used indoors. Many assume that the mist will damage appliances, soak papers and form puddles on the floor. All these assumptions are simply not true. Many misting fans are equipped with adjustable nozzles that can spray dry mist which evaporates right away.
- Backyard – Holding a barbecue party at the backyard is one way to spend time with loved ones. However, the heat emitted from the grill and the hot weather can be very uncomfortable for some. With a misting fan, this problem can be solved. In this case, a low pressure misting fan is already enough to cool the area.
How does it work?
When the water is sprayed into a mist, heat is transferred from the hot air molecules to the cooler water molecules. Since the air lost heat, the surrounding temperature will become cooler. The transferred heat is then used to turn water into vapor. This vapor also cools the surrounding even further. The fan also contributes by circulating the air and spreading the mist evenly across the area. In this way, more space is cooled down faster.
High vs. low pressure
- Low pressure misting fans only have pressures up to 100 psi or lower. There are usually no water pumps and because of this, the mister relies on the water pressure of the faucet. If the fan uses a storage tank as its water source, it relies on the specialized nozzle to create a mist. The lack of pressure sometimes results to a mist made up of bigger droplets of water. The bigger droplets will not evaporate as quickly as the smaller ones so people near the fan may feel these droplets touch their skin. However, the droplets are not big enough to get someone soaking wet.
- High pressure misting fans are the best type of misting fan one can have. The mist produced by the fan is fine and dry thanks to the high pressure build up behind the nozzle. The only problem with buying this is that it is expensive. Typically, they cost more than twice the price of the low pressure misting fans.
If money is nothing to worry about, buying the high pressure misting fan is the most advisable thing to do. It is a good investment especially when the misting fan is intended for cooling down a huge area packed with many people. For first time users who would want to first check the performance of a mister, choosing the low pressure type is the way to go.
