Frequently Asked Questions about Evaporative Air Coolers

Air coolers, also known as evaporative air coolers are portable, efficient, and environment friendly cooling options.

If you’re looking to buy an indoor or outdoor air cooler, we can assist you. The following are some of the most common questions we get about operating a portable evaporative air cooler:

 

How Does a Portable Evaporative Cooler Work?

An evaporating cooler is basically a device that draws in air and circulates it over wet cooling pads using a fan. The liquid water converts into a water vapours as the dry outside air passes through the wet pads, which is then blown out into the room by the air cooler. Water absorbs heat from the air, reducing the temperature of air and making the environment feel cooler. This is similar to the human body’s natural cooling mechanism. In the heat, the body sweats, which evaporates and lowers the body’s temperature.

Further, in case of dry climates, where air coolers are most effective, they provide humidity to the air, which can help with itchy eyes, dry skin, and sore throats.

Air coolers can be placed in windows, built into walls, on the floor, or are made portable. In case of centralised cooling, the air cooler is usually placed on the top of a home or commercial building, and a blower/heavy exhaust fan of air cooler forces the air down through air ducting.

 

Are evaporative coolers only effective in dry climates?

Evaporative coolers can be used in outdoor or semi-outdoor locations (such as garages, porches, and backyards) anyplace in the Country, even in humid climates.

As these coolers work by adding moisture to the air, therefore, if you reside in an area where it is frequently humid and hot, avoid using them indoors. Adding additional humidity, despite the cool air you’re bringing in, can make your area feel muggy.

It is important to choose a cooler that can cool the space in which it will be used. The amount of air provided is measured in CFM (Cubic Feet per Minute).

 

Tips for effective use of evaporative coolers:

  • Keep an eye on the weather while you use the cooler during hot days and seasons.
  • Experiment with several placements for the unit to get the best airflowand cooling.
  • When the cooler is first turned on, the cooling pads will need some time to absorb the water. Fill the water reservoir to prime the pads, giving them time to absorb the water so that when the cooler is turned on and the machine is running at full cooling capability.
  • Use water that is cool or at room temperature. Water from the tap (upto about 30 degrees celcius) is usually sufficient.

 

Will an indoor air cooler cool as well as an air conditioner?

Evaporative coolers lower the temperature significantly, but unlike air conditioners, they cannot be regulated to maintain a specific temperature. In some cases, such as single rooms in arid areas, they can replace air conditioners.

A window AC or split AC, on the other hand is a good option if you want to choose your preferred temperature and have the unit maintain temperature for you.

Follow these three steps to get the best results from an evaporative cooler:

Use the Right Size Cooler

Remember that domestic evaporative air coolers are room cooling solutions, which means they can only cool one room at a time. Hence, use the correct size cooler for the area.

Have a Fresh Air Supply

Allow sufficient fresh airflow by opening a window or door in the cooling space. If you don’t do this, the humidity will build up in the space, causing the temperature to rise. This is avoided by having a constant supply of fresh air.

Keep Up with Maintenance

To ensure effective cooling, you’ll need to replace the cooling media in your evaporative air cooler on a regular basis. In addition, you’ll need to keep track of refill and cleaning of the water reservoir as needed.

 

How do I determine what size air cooler I need?

When deciding on a size, it’s a good idea to calculate the CFM, or cubic feet of airflow per minute, an air cooler should have to properly cool your area.

CFM stands for cubic feet per minute of fresh air cycled through and cooled by the cooler.

Divide the cubic feet of your room by two to determine the required CFM. For example, suppose your room is 300 square feet in size and the ceiling is 10 feet high. The needed CFM would then be 1,500 (300 sq ft x 10 ft/2). Whether an air cooler uses a blower or a fan also affects the airflow.

 

Why are room air coolers considered more efficient and eco-friendly than air conditioners?

To make the cooling process easier, they don’t use energy-intensive compressors or dangerous poisonous refrigerants, they use water as the refrigerant. The compressor in your air conditioner, not the fan, consumes the most energy and is the primary cause of your high cooling bill. Because you’re using less energy, cooling with an evaporative cooler can cost up to 80% less than cooling with a typical air conditioner in some situations. An air cooler does not require installation, which is a time-consuming process with an air conditioner. Many air coolers are also equipped with castors, making it easier to transport them from one area to another.

 

Does a room air cooler make everything in your room damp?

No, evaporation is the key to their cooling process.

Before being released, dry air acquires moisture from the water-soaked cooling pad as it passes through the evaporative cooler. This mechanism evaporates the tiniest water droplets into the air, moisturizing and cooling it invisibly.

This procedure will not wet your room’s contents or make you feel moist.

 

Do you run a room air cooler all night?

It is perfectly okay to sleep with your evaporative air cooler on for health reasons. In fact, this is one of the machine’s key advantages over traditional air conditioners.

It generally does not cool the room as effectively as a traditional air conditioner. When using air coolers, the odds of becoming excessively cold to the point of feeling nauseous are nearly non-existent.

Even though the quality of air produced by air cooling solutions is always under doubt when it comes to health safety. While there is a chance that the air quality from air conditioners will be harmed, this is much less likely with air coolers.

This is due to the fact that air coolers are simple machines that rely on the natural cooling mechanism of evaporation. As a result of the usage of air and water in the process, the air produced is always pure.

Air coolers, once again, do not recirculate the same stale air. It pulls in fresh air from outside while removing stale air from the room. When fresh air goes through the moist cooling pads inside the machine, it is also filtered. Overall, the air quality from the air cooler is always good. This means that using it overnight poses almost no health risk.

 

How long should I run the pump on my air cooler?

You should only run the pump for as long as the reservoir is full of water. The pump will overheat and eventually burn out if it runs without water.

Most evaporative coolers may run the fan without water, if you run only the fan without water, it is only for purpose of recirculating air, not cooling.

 

How do I clean my air cooler?

It’s necessary to clean your evaporative cooler’s water reservoir or water pan on a regular basis, just like humidifiers. Drain your evaporative cooler once a week as a general guideline to avoid fungus growth.

How much does it cost to run a room air cooler all day?

A-rated air cooler power ranges from 150 to 300 watts, which is fairly low considering the cooling impact they provide. A 200-watt air cooler that runs for 5 hours per day consumes 1 kWh of electricity per day and 30 kWh of electricity per month.
