Buying Guide: Things to Consider When Buying an Air Cooler for Your Space
Keeping your indoor environment cool and comfortable during warm summer months can be a frustrating and often expensive task, some air cooler manufacturers such as the likes of LG, Samsung, Scanfrost, Haier Thermocool to mention a few offer eco-friendly, healthy, and cost-effective alternatives to traditional air conditioning systems.
However, there are some things to take into consideration before purchasing an evaporative cooler.
1. Do I live in a climate where an evaporative cooler would be effective?
Evaporative cooling is a simple, cost-effective method for cooling indoor spaces. However, depending on the climate where you live, evaporative cooling might not be the most effective option for you. Thus, understanding how evaporative air coolers work will help you decide if this is the right cooling solution for you. Evaporative cooling occurs naturally all around us. This absorption occurs when the temperature and vapour pressure of the water attempt to equalize with the air. As a result, water molecules turn into gas molecules and heat switches from the higher air temperature to the lower water temperature. Since the air circulates naturally, the area around it is cooled.
To consistently cool your home, residential evaporative air coolers build on this natural phenomenon, using a fan to draw warm, stale air inside the unit, where it passes over water-moistened pads to be cooled. During this process, the air is cooled up to 20 degrees. Then, the cool, rejuvenated air is circulated throughout your environment. Since the cool air is continually circulating and creating a breeze, your ambient temperature can feel four to six degrees lower than the actual temperature.
2. How do air coolers compare with traditional air conditioning systems in terms of cost-effectiveness, energy efficiency, and environmental impact?
The goal of both air coolers and Air Conditioners is to cool your space. However, air coolers are available at a lower overall price point, are more energy efficient, and are much more environmentally friendly than traditional air conditioning systems.
The use of simple technology to cool your indoor air helps portable air coolers excel at energy efficiency. When compared to air conditioners that use refrigerated cooling systems, operating air coolers costs up to 50 percent less. In fact, a 36-inch evaporative air cooler operating for eight hours typically costs less than one dollar because the only costs associated with operating it are water and electricity. This is almost three times cheaper than traditional cooling costs.
For environmentally conscious consumers, air coolers are an ideal solution for keeping cool without harming the environment. Unlike air conditioners that use refrigerants to cool your home, air coolers use a natural process that cools the air using motion and water. This process won't add ozone-harming pollutants or other chemicals to the environment.
Furthermore, air coolers actually work best when fresh air is available, such as from an open window or door. This constant circulation ensures that your indoor air is fresher than it would be with traditional air conditioners that require an airtight space to operate. Plus, the evaporative cooling process naturally humidifies dry air - reducing dry air symptoms such as itchy eyes, throat, or skin.
3. What size evaporative air cooler will be most effective for my space?
To get the best results from your evaporative water cooler, make sure it is the correct size for your space. For example, an evaporative water cooler that is too small for your area will have to work extra hard to keep the space cool, wasting energy.
The CFM (Cubic Feet per Minute) is the amount of fresh air cycled through your environment each minute. To find the CFM, follow this formula:
Square feet needed to be cooled multiplied by ceiling height (in feet). Then divide this number by 2.
For example, if your room is 450 square feet with 8-foot ceilings:
450 X 8 / 2 = 1,800 CFM
According to the equation, you would need an air cooler with a CFM of at least 1,800.
4. How much maintenance does an air cooler require?
Although caring for portable air coolers require very little maintenance overall. Basic cleanings and proper storage/shut down of the appliance are the primary factors in determining the performance and life of your evaporative air cooler.
The filter and water curtains of the portable evaporative cooler should be cleaned once every two weeks with lukewarm water and a mild detergent to avoid dust, dirt, mould, and mildew build-up, especially if the device has been used for long periods of time. The outer housing of the portable swamp cooler should also be cleaned periodically with a damp cloth. When you have finished using your portable air cooler for the season, simply wipe it clean, drain the water tank, clean the filter and water curtain, and operate the fan-only function (if available) for 30 to 60 minutes to completely dry the device before storing.
