Picking the right air cooler fan though can be a little confusing. There are plenty of options in the market and many more features to consider. In this article, we take a brief look at all the important features one should consider while buying an Air cooler fan for your home:
Overview types of evaporative air coolers
Evaporative air coolers come in many types and these are:
- Portable residential coors usually are ideal in cooling small rooms of up to 30 ㎡
- Window or wall-mounted coolers can cool an entire room or the whole house or garage
- Down discharge coolers are placed on the roof, releasing the cooled air descending into the edifice and are intended to cool the whole home.
- Slide discharge coolers are usually placed in the side of the building but can also be placed in the roof, using an elbow to run the wind current through an opening in the top. It can cool the whole house.
- Portable commercial coolers are more adept to be used in larger spaces such as garages or warehouses and even outdoors like in patios.
So choose the right type of Air cooler fan before buying. In this article, we’ll pay more attention to the tips that you should consider when buying air cooler fan(or portable residential coolers).
Which areas are most effective for Evaporative Coolers?
Evaporative cooling is among the earliest forms of weather and climate control still in use today, It is a simple, cost-effective method. Remember that breezing feeling you have on your skin after coming out of a pool? That is the simple idea of air coolers. However, depending on the climate where you live, Thus, Here a map to get the answer:
More parts of the world have been highlighted as areas where evaporative air coolers operate excellently.The world map of world for a huge green band and These areas have hot and dry climates that favor evaporative cooler. They are middle east, Central Asia, southern Europe and the West Coast of USA, Southern Africa, and Latin America.
The areas marked yellow are slightly cooler and are more prone to humidity. These areas include the United Kingdom and Western Europe where this technology works sufficiently well, but not at optimum efficiency. According to science, as global warming intensifies, these regions will develop a hotter climate that favors evaporating cooling techniques, implying that air cooler fan will be cheaper and much more efficient.
How do evaporative cooling compare with traditional air conditioning?
The goal of both of evaporative air cooler and traditional ACs is to cool your space. However, air cooler fans are less operating cost, energy efficient, and are much more environmentally friendly than traditional air conditioning systems. Here is a small table comparing the differences between two types.
What size evaporative swamp cooler will be suitable for my home?
Before buying an air cooler fan, you should take into account the size of the area you need to be cooled or the number of rooms you need to be cooled since coolers have varying capacities in cooling spaces. A bigger space may require a bigger unit for cooling and in the same manner; a smaller unit may be ample for a smaller space. The goal is to supply the consumers with the ideal evaporative air cooler that will work efficiently to maintain cooling without wasting energy.
To find the best evaporative cooler that will be appropriate for your needs then calculating the airflow rate should be done.
- So how to calculate CMH(m³/h) requirement of your Cooler ?
There is a simple way to calculate. Just follow the example to calculate the CMH of the cooler.
Room Length: 6 meters
Room Width: 5 meters
Room Height: 3 meters
Volume of the Room: Length x Width x Height = 6 x 5 x 3 = 90 m³
Air exchange times in an hour: 20 times
Total volume of Air to be replaced in one hour: 90 cubic meters x 20 times = 1800 cubic meters per hour
This is the CMH (cubic meters per hour) requirement for your cooler: 1800 m³/h
So if the airflow of the single unit is 1800 CMH, you need one unit. Or if the airflow of the single unit is 900 CMH, you’ll need 2 units.
P.S.: Generally 20-30 air exchange times will be enough for your room.
- Choosing Air Cooler size
This is probably one of the most obvious things to do prior to getting an evaporative air cooler. In cases where in you have decided to buy a portable evaporative cooler, you have to note if it has enough room to be moved around.
12 features of air cooler fan
Air cooler fan come with a variety of features but here are some of the important ones that can be of great benefit to you.
1. Cooling pad thickness and quantity
Cooling pads have a direct impact on the cooling of an air cooler. They absorb water and allow air to flow through them to cool it. Thicker the cooling pad, the better the cooling.
Cooling pads are generally made of aspen or cellulose material. Both have their advantages and disadvantages. Aspen pads are made of wood shavings and synthetic fibre. They are cheaper, need high maintenance and have a shorter life. Cellulose cooling pads are also known as honeycomb pads, mostly because they look like a honeycomb. They are thicker in comparison to aspen pads and have low maintenance and a higher life. They cost a little more but are also known to be more efficient.
Additionally, you also have to check the cooling pad quantity for each cooler. Some Air cooler fan only have single cooling pad, while some other have 3 or 4 cooling pads. It will gets better cooling performance once has more pieces of cooling pads.
2. Power consumption
With many evaporative air coolers comes varying energy efficiency. It is best to ask your dealer on what brand of evaporative air cooler is the most energy efficient, thus will have less negative impact on the environment.
3. Variable speeds and air mode
Variable speed coolers are used to control the speed of the fan. It is better if the cooler has options for regulating speed.Also some air coolers offers 3 different air mode like natural mode,normal mode and sleeping mode.
4. Water tank capacity
Air cooler fan make use of an evaporative cooling method. In this method, water is converted into water vapour, which reduces the temperature of the air blown by the fan or blower. It’s important to have air coolers that have large water tanks. Larger the water tank, the longer the air cooler will run. You need to select an air cooler that has a water tank that is the right size for your everyday use. A larger room would also require an air cooler with a larger tank. Both residential and commercial portable air coolers come with a wide range of water tanks sizes. Residential air coolers have tanks of 20 to 30 liters capacities while commercial air coolers capacities range from 40 to 120 liters
5. Garden hose connector
You can also call it at automatic water level controller. Some units have a hose connector.
This connector allows employing a standard garden hose to be attached to the unit for continuous supply of water is delivered to the unit while in use. It saves you the time and energy of manually pouring water into the reservoir.
6. Fan types
Evaporative air coolers can either be equipped with a centrifugal fan or an axial fan. The centrifugal fan is drum-shaped and is generally quieter but consumes more energy for cooling and costs more than the axial fan. The axial fan, on the other hand, is cheaper, uses less energy but is much noisier.
7. Water level indicator
Check if the portable air cooler fan has a water level indicator or not.
It will be more convenient for you to check the water level and know when it’s needed to add water. Anyway, it the air cooler already has a garden hose connector, such water level indicator is not necessary any more.
Check the castors that the Air cooler fan used. Some air coolers just use some simple plastic castors which could not be used for a long time, especially when you have to move the air coolers frequently. It’s better to choose the coolers with heavy duty castors which use thick rubber and strong metal materials.
9. Remote control
For quick access to settings, look for an Air cooler fan that comes with a remote. Remotes for air coolers will let you control the speed of the fan so you don’t have to get up over and over again to change the settings.
10. Warranty period
Check if the air cooler supplier could offer warranty for their products or not? if yes, how long? Generally some famous brands will offer one year warranty while some other might offer longer warranty.
11. Price & Shipping fee
There are a lot of evaporative Air cooler fan currently available and they vary in prices and quality. There are those that are high priced but do have a number of extra special features, low energy consumption, water saving and much quieter than the cheaper brands. It is basically your discretion and you just have to weigh in on each of the unit’s advantages and disadvantages in relation to their respective prices.
Also you should consider that if the price is including shipping freight or not. Some agents sell the air cooler with free shipping while some other not.
Once you have decided the type and size of air cooler, after that the next important step is to choose the brand. Some popular brands of air coolers are Portacool (for commercial air coolers),Honeywell(for residential coolers),etc. While if you want to be an air cooler dealer and buy air coolers in bulk, you should consider the manufacturers to get a more competitive price. Vankool could be a good choice for wholesale business since it has been the OEM supplier for Honeywell for more than 12 years.
