Portable Evaporative Cooler

Portable Evaporative Cooler is among the perfect cooling solutions for those places which are hot & dry. Air coolers function by evaporating water to lower heat and moisturize the air in a process similar to natural processes. They are more eco-friendly and efficient in energy consumption than traditional air conditioners. Choosing the best air cooler may be a daunting task though. Several options exist in the market that presents several features that you ought to consider. In the article, we are going to have a brief overview of the important features that one ought to consider when they are purchasing an Air cooler fan that will suit your home best:

Am I in the correct climate for an evaporative cooler? 

Evaporative air coolers utilized this phenomenon to regularly cool your place. They used a fan that pulled warm and stale air through this unit which later passed over some water-moistened pads for cooling. Through this procedure, the temperature of air is at twenty degrees. The renewed cool air then runs through your environment. You will feel the temperature difference down to 4-6 degrees lower than the real temperature because the cool air keeps circulating & creating a breeze.

The appropriate climate for proper cooling of your home using an evaporative cooler is hot and dry air which is the same as the climate that is found in the desert areas. To be precise, swamp coolers are the best amid the hot times of the day & when the humidity levels are just below fifty per cent. The portable air coolers won’t work well in a high humid environment. They work well in dry areas in order to improve the air quality by simply adding water vapor. Evaporative coolers however can similarly work well in humid conditions but it is only when placed in semi-outdoor & outdoor conditions. Due to the potential of excessive moisture which might build-up indoors, an open door or door should be mandatory for applying a swamp cooler, & usage isn’t recommended for indoor use for the humid climates.

How to select the correct size?

If you interested in getting the perfect performance from your cooler, ensure to purchase the correct size which is fit for your space. In case your air cooler is small, it implies that the cooler must work a bit harder to cool your space that is going to similarly waste much energy.

How do you calculate CMH(m3/h) need of your cooler?

There is an easy simple way of calculating. Just take after the example below in order to calculate the CMH of your cooler.
Length of the room: 6 meters
Width of the room: 4 meters
Height of the room: 2.5 meters
Room Volume: Length x Width x Height = 6 x 4 x 2.5 = 60 m3
Number of times that air should be replaced per hour: 20 times
Entire air volume that should be replaced per hour: 60 cubic meters x 20 times = 1200 cubic meters per hour
This is the CMH (cubic meters per hour) need for your cooler: 1200 m3/h

SQUARE METER AREA X CEILING HEIGHT X AIR EXCHANGE TIMES = CMH OF AIRFLOW NEEDED.

Remarks:

The specific number of times that air should be replaced will depend on the particular environment, here are some suggestions for reference:

12 factors which you should consider when choosing an air cooler

Air cooler fans accompany various features but below are among of the vital ones which can be of much benefit to you.

1. Thickness & quantity of the cooling pad
Cooling pads usually have a direct effect on the cooling of your air cooler. What they do is to absorb water & allow some air to flow into them in order to cool it. The thicker your cooling pad is the perfect the cooling.

Cooling pads are simply made of aspen or a cellulose material. Both of them have their pros and cons. Aspen pads come from wood shavings & synthetic fibre. These are cheaper, they however require high maintenance & just have a short life. Cooling pads made of cellulose are similarly referred to as honeycomb pads, mainly because they resemble a honeycomb. They are much thicker as compared to their aspen counterparts & they have minimal maintenance and normally last for a longer time. They are a little bit expensive but this is attributed to their efficiency.

On top of that, you are required have to look at the quantity of the cooling pad for every cooler. Some fans just have one cooling pad, while others have three to four cooling pads. An air cooler that has many cooling pads will get a better cooling performance.

2. Power consumption
Various evaporative air coolers have different energy efficiency. It’s best to enquire from your dealer about the brand of the evaporative air cooler that is most energy efficient which will therefore have minimal negative impacts to the environment.

3. Variable speeds & the air mode
Variable speed coolers generally control the fan’s speed. It is even better when your cooler has options that allow you to regulate speed. Similarly some air coolers will offer three different air modes such as natural, normal & sleeping modes.

4. The capacity of the water tank 
An air cooler fan utilizes an evaporative method of cooling. In this particular method, water is usually converted to vapour that lowers the air temperature which is blown by either the blower or the fan. It is essential to have those air coolers which have larger water tanks. The larger the tank, the longer the duration of time that your air cooler is going to run. You should select that air cooler which has a right size water tank for your daily utilization. A bigger room would similarly need an air cooler that has a bigger tank. Both residential & commercial air coolers that are portable accompany wide range sizes of water tanks. Residential air coolers accompany tanks that have a capacity of twenty to thirty liters while the commercial ones have a capacity of forty to one hundred and twenty liters

5. Garden hose connector
It is also referred to as an automatic water level controller. Some units will have a hose connector. The connector permits employing a normal garden hose which is attached to the unit in order to ensure continuous water supply to the unit while it is in operation. It saves one the time & energy of pouring water manually into the reservoir.

6. Fan types
Evaporative air coolers may be equipped with either an axial fan or a centrifugal fan. A centrifugal fan is usually drum-shaped & it’s quieter but consumes much energy for cooling despite costing more as compared to the axial fan. This fan (axial fan) is cheaper and uses less energy though it is noisier.

7. Water level indicator
Check whether your air cooler fan contains the water level indicator.
It is going to be much convenient for one to have a look at the water level in order to know when to add water. If however your air cooler has a garden hose connector already, such an indicator isn’t necessary at all.

8. Castors
Have a look at the castors which your air cooler fan utilizes. Some of these air coolers just utilize some plastic castors that couldn’t be utilized for a long period of time, particularly if you will be required to move your air coolers often. It is a good idea to select those coolers that have heavy duty castors that utilize thick rubber & strong metal materials.

9. Remote control
For easy access to the settings, check for those air cooler fans which accompany a remote. Air cooler remotes let one control the fan speed such that one doesn’t have to get up every other time in order to change these settings.

10. Warranty period
Check to see whether the supplier of your air cooler offers warranty on their products. If they do, you should know the time duration too. Essentially some well-known brands offer a one year warranty while other brands may offer a longer warranty.

11. Price and the Shipping fee
There are many evaporative Air cooler fans that are currently available & they have different prices & quality. Some are highly priced due to the fact that they possess extra special features such as lower energy consumption, saving water & they are quieter as compared to the cheaper brands. It’s essentially your own discretion & you will just weigh in on every of these units pros and cons with respect to their prices.

You should also consider whether the price includes the shipping freight or not. You will get agents who sell their air cooler with some free shipping while some agents will not.

12. Brands
After settling on the size & the sort of your air cooler, the next crucial step is choosing the brand. Some famous brands include Portacool and Honeywell for commercial and residential coolers respectively. In case you aspire being an air cooler dealer where you buy the air coolers in bulk, at that point you need to consider the manufacturers so that you can get a much competitive price. Vankool will be the best choice for a wholesale business because it has been the sole OEM supplier for Honeywell for a period of more than twelve years.
