Evaporative air cooler Intro
When you see the words “evaporative air cooler” we are referring to a device designed to cool air through the evaporation of water. Though, these devices might produce similar results just like a typical air conditioning system but surely not the same.
A typical air conditioning system uses vapor-compression or absorption refrigeration cycles while evaporative air cooling simply refers to a process that uses the effect of evaporation as a natural method to absorb heat. We are going to discuss more this later.
A cool environment is highly desired especially during hot weather but thanks to modern technology that made it possible for us to work out and determine how warm or cooled our environment will be through various means.
We understand that you landed to this page with some important questions to ask or probably to find an answer to your questions but we surely have some answers. We are going to discuss the followings:
- What is an evaporative air cooler
- How does evaporative air cooler works
- what is a portable evaporative air cooler
- How to use evaporative air cooler
- what is an indoor evaporative air cooler
- what is the best evaporative air cooler
- when to use an evaporative cooler or air conditioner
What is evaporative air cooler?
Before we proceed it will be important to understand what evaporative air cooler is all about. However, let me remind you that Evaporative coolers can also be called swamp cooler, swamp box, desert cooler, and wet air cooler so don’t get confused when such name pops up.
Evaporative air coolers are one of the climate control devices that provide a friendly and healthy temperature relief in a commercial and industrial environment. In other words, evaporative air coolers are more economical compared to the traditional air conditioning systems.
It’s clear that swamp coolers can be of great help mostly in warm summer months but one simple truth is that they are not as effective as they are designed to be in some climate. The best way to determine whether an evaporative air cooling system will work for you is to first understand how it works.
It’s proven that swamp coolers work best in dry climates because these types of air coolers add moisture to the air while cooling. Obviously, when you live in a humid or hot climate then the use of evaporative air cooling system might add more humidity which actually produces hot temperature undermining the activeness of the cooling system.
However, any climate similar to the southwestern United States will be a perfect fit for any type of evaporative air coolers and yes the effectiveness of swamp coolers is greatly affected by the climate.
How does evaporative air cooler works
Whether you call it Evaporative cooling or evaporative air conditioning it’s a process of using evaporation to cool the air in an evaporative cooler. However, it involves pumps that help in circulating water from the reservoir directly to the cooling pad, making it possible for the pad to become wet.
There is a fan in almost every evaporative air coolers that helps draw air outside through the moistened pad, the air is cooled by evaporation as it passes through the pad. To maximize the effectiveness of any evaporative cooling system you must ensure that the cooling pads are well saturated. Moreover, a good evaporative cooling system unit should come with a perfect sized fan and motor that delivers appropriate airflow.
Basically, swamp coolers are mostly designed for indoor cooling purposes but their output is determined by the type, size and capacity. To determine the type and size of air coolers you need, you need to consider whether you are going to use it in a commercial or industrial environment.
To fully understand what evaporation is all about you can experiment how it works by following this method. When in a warm summer season and try to place your arm in a bucket of warm water at your own convenient time and simply remove your leg to feel a slight chill on the wet spot.
This is only possible due to the evaporation of the water on your arm and the real action of evaporation is the “energy” that produced the cooling.
The direct and indirect evaporative cooling system
An evaporative cooling system can be classified into a direct evaporative system known as an open circuit and indirect as a closed circuit cooling system. The direct evaporative is designed to help lower the temperature while increasing the humidity of air making use of latent heat of evaporation. This method made it possible to change warm dry air into cool moist air.
The indirect evaporative cooling system is another method that makes use of direct evaporative cooling to circulate the cool energy to the supply air. However, the main reason why this system is called indirect because the cooled moist air that comes from the evaporative cooling process doesn’t have direct contact with the habituated supply air.
What is the difference between an evaporative cooler and an air conditioner?
This question must be ringing in your head right now but I will definitely clear your mind. Sincerely both of them are good in their respective ways.
Cost and maintenance
If you are looking for a way to reduce the cost of cooling your home and save some electricity bills then evaporative energy is what you need because air conditioner are more expensive and as well require more energy to power it compressor. Evaporative cooler don’t need a compressor to perform it duties.
Swamp coolers can easily be maintained since its can be position anywhere inside or outside the room and offices which means it’s reachable at all time unlike air conditioners. Besides swamp air coolers doesn’t require much maintenance apart from cleaning the cooling media and refilling the water tank etc.
Installation and Ease of use
Evaporative coolers are still winning over air conditioners in this regard as most of them don’t require any installation while you need the services of an expert to install some air conditioners.
Both of them are easy to operate either directly through the panel or through remote control.
