Recently, there are many mist fan appearing in Singapore eating places and open areas. Have you ever thought of putting an indoor mist fan in your aircon room? Is it advisable to do so? Can I service the aircon less often with mist fan?
Recapping on How Aircon Works
We mentioned in another page on how aircon works and also video on refrigerant cycle. Aircon basically blow air on cold surfaces to generate cold air. The heat of the cold surfaces is absorbed by the liquid refrigerant when it evaporates to gas refrigerant. The gas refrigerant travels to the compressor-condenser unit where it releases heat by condensing to form liquid refrigerant.
How Mist Fan Works
Misting fan forces water through tiny holes and spray these fine water droplets or mist into air. When the fan blow the mist into the air, it accelerates the evaporation process and cools the surrounding. During evaporation process, heat is required and as such it cools down the surrounding. This is the same theory as applying more heat to speed up evaporation. In the case of mist fan, we speed up evaporation by increasing the surface area of water exposing to air and as such, heat is taken up during the evaporation process of the water droplets or mist.
The droplets are so fine that you should not be wet if you are not too close to it. With mist fan, the room will cool faster than conventional fan. By putting mist fan in the aircon room, you doubling the evaporation process, one through the aircon and another through mist fan.
Moreover, the evaporation in the aircon room will be faster than outdoor in Singapore. When the fan coil blow air on cold surfaces, the water vapour condenses and is drained away. This lowers the humidity level of the air in the room. With lower humidity, it means that the mist produced by the mist fan should evaporate faster or instantaneously when it is blown out.
Humidifier Effect by Mist Fan
The mist fan also act as a humidifier in an aircon room and maintain the humidity of the room. This means that you need not separately buy an humidifier. Having a reasonable humidity level in the room is critical for babies and promote better skin condition for adults.
As fan uses less electricity than aircon, cooling the room with mist fan should be more energy efficiency. The only issue about mist fan is that it takes up some space in the room. Though there is ceiling mist fan, the design may not be very nice at the moment.
Many of you would have heard of mist fan. Have you ever thought of putting an indoor mist fan in your aircon room? Will this arrangement work? This arrangement should work well. It may even reduce the frequency of your aircon servicing.
