What is an Evaporative Air Cooler?
Quilo’s evaporative cooler, also known as a swamp cooler, desert cooler and wet air cooler, is a device that cools air through the evaporation of water. They also happen to be an environmentally- and economically-viable cooling alternative for your home and office. As water evaporates and the fan blows the resultant air (which is now cooled down) out, a cool and light breeze is released. It’ll make you feel as though you’re sitting right beside a gushing waterfall!
How do air coolers work?
As the fan draws in air from outside into Quilo’s air cooler, it comes in contact with the wet cooling pad. The air, upon mixing with this water, causes the water to evaporate and lose its heat. What you get is a much cooler and moisturized air, which is then propelled by a powerful fan, ensuring a steady flow of fresh air. The stale air is simultaneously dispelled out.
Why does evaporation cause lower temperature of air?
Upon evaporation, that is when water converts into vapors, the temperature of the surrounding dry air drops sharply. Evaporation can be witnessed everywhere in the environment, be it our bodies (when we perspire), or the water cycle that precipitates rain.
How is an air cooler different from a standard fan?
A regular fan merely circulates the air in a room without offering much respite from the heat. Air coolers, on the other hand, by way of evaporation, cool the incoming hot air and blow it across.
How is an air cooler different from a mist fan?
Designed mainly for outdoor use, mist fans actually spray water while distributing air and thus help in keeping the area cool. These mist fans come handy when air conditioning is not an option. A good mist fan does not make the place a wet mess. The tiny water droplets that are spritzed into the air, lower the surrounding temperature and the droplets are eventually evaporated. However, having a constant water supply is a prerequisite as there’s no option for storing water.
How is an air cooler different from an air conditioner?
An air conditioner works on the principle of drawing warm air in from an enclosed room, cooling it through the coils present in the indoor unit of the AC and emitting the cool air through the room, in a short span of time. Unlike air coolers, it uses refrigerants in order to bring down the temperature and it also causes the air to become dry. Quite naturally, they are expensive, energy-consuming, and bad for the environment.
How do Quilo’s cooling pads help in cooling the air?
Quilo air coolers use special cooling pads to cool the surrounding air. It supersedes other such pads as Quilo’s cooling pads have a greater surface area for the evaporation to take place.
Are Air Coolers effective in humid environments?
Quilo air coolers perform most effectively when the relative humidity is 60% or below. Lesser the humidity, greater will be the temperature drop. Dry air is necessary for a better evaporation process. They are most useful during dry weather conditions, wherein can be used to treat dry skin. However, this doesn’t mean that they become redundant during humid conditions as they’re still the most cost-effective option, which can anyway be used during the drier hours of the day. They’re also the best in providing ventilation. Wherever feasible, they can be used in addition to the air conditioners. Switching on your air conditioner even for a short while (while keep the cooler on) will cool down the room quite fast.
How can I improve the performance of my air cooler?
Ensure adequate cross ventilation
While using air coolers, ensure that there is at least a small space for the cool air to escape from the room, otherwise the humidity might make you feel uncomfortable. You are also suggested to leave doors and windows slightly open to allow the free flow of air. An air cooler works optimally when placed near an open window so that the air can escape unhindered.
Check the humidity of your room
Quilo’s air coolers perform best when the relative humidity is 60% or below. Lesser the humidity, greater will be the temperature dip. Dry air is necessary for a better evaporation process. However, this doesn’t mean that they aren’t useful during humid conditions as they’re still the most cost-effective option in the market and can be used during the drier hours of the day. They can also be used in addition to the air conditioners. Switching on your air conditioner even for a short while (while keep the cooler on) will make a huge difference to the temperature of a room.
How do I choose the right air cooler for my space?
Choose the right-sized cooler for your room
Spot coolers are the smaller-sized, compact air coolers intended to cool the nearby area around the cooler. Room coolers are bulkier but their powerful airflow makes them ideal for cooling larger spaces, such as living or dining rooms. Outdoor coolers have large water tanks and an exceedingly powerful airflow. They’re also UV & weather resistant. All these factors make them the perfect choice when you need to cool outdoor areas, such as your patio or backyard.
Find out the airflow of your air cooler
Check for CFM (Cubic Feet per Minute) or m3/hour rating of the air cooler. These indicate the amount of air passing through the air cooler per minute (or hour). The higher an air cooler’s CFM rating, the wider would be the coverage area of cooling.
Water tanks have no impact on the performance of air coolers. However, as it might be time-consuming to refill the tank every time it empties out, larger ones are preferred when the room to be cooled is larger in size or is located outdoors. Additionally, some room coolers and outdoor coolers have a built-in continuous-water supply connection that can be linked to your home’s water hose for easy tank refills.
