Can we get through the summer heat by using a solution that promises high-energy efficiency? A Portable Evaporative Cooler is capable of delivering a high level of cooling power in a highly effective way. Interestingly, it also consumes less energy while delivering unmatched cooling power. An Evaporative Cooler is a device which is also referred to by many as a swamp cooler. It is a unique cooling device that is suitable for the dryer climates. This explains why they are widely used in the West. The cooling system is inexpensive to acquire and cheap to operate as well.

An evaporative cooling system functions by introducing water vapor into the atmosphere, which helps to lower the temperatures. The concept of evaporative cooling is actually a natural phenomenon, which often occurs virtually everywhere in our surroundings. To understand the concept, you can simply turn on your garden sprinklers. When you stand adjacent to the area of your yard being watered, you’ll notice that the air is much cooler. This is similar to the concept of evaporative cooling.

Now more and more people choose to use portable evaporative coolers which could offer an eco-friendly and cost-effective to conventional air conditioners. However, there are some things you have to know before purchasing portable air coolers.

1. Where applicable for Evaporative cooler ?

Evaporative coolers are more eco-friendly and efficient in energy consumption than AC. Typically, they are also more powerful than normal fans. They are used to cool include Church ,Coffee Shop, Computer Shop, Factory, Farm, Fastfood, Grocery, Gym, Hospital, Industrial, Hotel, Home, Kitchen, Laundry Shop, School , Shopping Mall, Showroom, Warehouse, etc.

2. Do I live in the right climate for the evaporative cooler?

In areas experiencing high temperatures and low humidity, evaporative coolers effectively lower temperatures to as low as 20 – 40 degrees Fahrenheit. However, in instances of high humidity, the cooler cannot cool you down effectively. Check your location’s summertime temperatures as well as relative humidity to determine whether the cooling system will work for you.

As a general rule, if a cooler produces air colder than 70°F, it will create a comfortable environment; if it produces air hotter than 75°F, it will not. Between 70°F and 75°F is a gray range in which some people are comfortable and some are not.

3. What are the benefits of using a Portable Evaporative Cooler?

– Super Energy Efficient:

Using portable air coolers is very cost-effective to cool your place without spending much money on electricity. Swamp coolers cost up to 50 percent less than air conditioners that use refrigerated cooling systems. Imagine that, a 36-inch swamp cooler working for 8 hours typically costs you less than $1! Because the operating costs needed are only for water and electricity. Even some swamp cooler designs don’t need any electricity.

– Zero Emissions

Since the system leaves a low level of carbon footprint, it produces no emissions. Unlike other traditional cooling systems, the evaporative cooler has no refrigerant gas or compressor. Furthermore, it releases no toxic chemicals in the air. Swamp cooling systems use no refrigerants that potentially harm the environment. Most refrigerant chemicals used in air conditioning systems deplete the earth’s ozone layer. As a result, they cause global warming to occur.

– Prevent of Air Pollution

The cooler is fitted with a filter to help filter out odor-causing pollutants and dirt from the indoor atmosphere. Consequently, the quality of indoor air in your rooms will be improved significantly. Apart from being eco-friendly, the cooler additionally safeguards the rooms of your home from air pollution. The Airy Plant is yet another highly innovative product widely used to purify air in an efficient way without energy.

– Portable and Practical

You can easily drag the cooler to any room. You can also pack the device easily, as it was designed to be moved around effortlessly.

– Cost-Effective Setup

Unlike the traditional air conditioners, you can set up your portable evaporative cooler in an inexpensive way. These systems are cost-efficient considering there is no need to set aside any amount for installing the device. You can buy the evaporating cooler from the online stores and simply install it in any of your rooms. After a certain period has elapsed, it is recommended that you clean the water tank, the motor, and filter components. Thankfully, you can perform the tasks with no prior expertise or experience.

– Adds Moisture

The evaporative cooling devices boost the level of moisture inside your home. Therefore, if you live in a region that experiences dryer climatic conditions, the cooler will come in handy. The standard AC systems have a major downside. Unlike the evaporative cooler, the traditional AC units take out moisture from the environment indoors. Note that eliminating moisture from the indoor atmosphere potentially causes breathing difficulties. Furthermore, it is likely to cause cracking or drying of skin.

4. Is there any shortcomings of using Evaporative Air Coolers?

– Since Evaporative Cooling Systems increase the level of humidity inside homes, do not use them in areas of humid climates. When compared to the traditional AC systems, Evaporative Coolers cool down your home to higher temperatures. Moreover, they require basic maintenance at least once every month.

– Portable air coolers are designed to use water continually. In the locations having limited supply of water, homeowners might be wary of adding the cooler considering their water-use impact.

– In areas experiencing low-humidity, evaporating water in the air allows homeowners to enjoy a highly energy-efficient and natural cooling method. Swamp Coolers work using this concept. These coolers cool the exterior air by letting it flow over water soaked pads. This, in turn, causes water in the pads to evaporate in the cooled air. The cooler air which reaches temperatures of between 15 °F – 40 °F is then guided into the house. The warmer air, on the other hand, is pushed outside through the windows.

5. The Differences Between Portable Air Coolers & Fans & Air Conditioners

Fighting the burning summer heat can be difficult. Therefore, the decision to buy an Air Cooler, AC system or fan presents you with options worth considering during summer. Even so, it is important that you choose the right device because each one has its own pros and cons. The comparison of them differences are listed below.

6. How To Select The Ideal Size Of Swamp Cooler For Your Room

The Evaporative Air Coolers are rated in terms of CMH (Cubic Meters Per Hour) of air delivered into a home. A vast majority of these coolers range between 2,500 – 13,000 Cubic Meters Per Hour. The manufacturers of the air cooling systems recommend that you provide sufficient air-moving capacity. Note that the capacity should range between twenty to forty air changes every hour based on the environment. Here’s some suggestions for your reference:

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

Number of times the air need to be replaced 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.

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