There is nothing better on a hot day than a room or home that is cool and relaxing where you can take a respite from the heat. Evaporative coolers are a new generation of air conditioner units that use the power of water evaporation to cool the air around them. The process works by physically changing the state of the water from liquid to gas(water vapor). This evaporation process absorbs a lot of heat and can lower air temperature considerably. Some units have the ability to cool down the air within the cooler up to 15 degrees, and as a fan blows the cold air out, it cools the room.

Active Aqua is a “big boy” of the evaporative coolers suitable for farming operations. It is great for hydroponic systems and aquaculture applications. With a tank of up to 40 gallons, this cooler chills more than just a room. Unless you are a farmer, you will probably not need a large unit like this one, but it is included in this list to illustrate the adaptability of the evaporative cooling technology. 

How do evaporative coolers work?

Each unit, depending on design, has a water source which is the key to producing cold air. The water is stored in a tank, or the unit is attached to a continuous supply. Warm air is drawn into the cooler, and the water is pumped through coils to start the evaporation process. The cooler is able to produce cool air by changing water into water vapor. The physical reaction of water changing from liquid to gas form absorbs heat, and the cold air is pushed out of the unit with the help of a fan. 

The tank is usually mounted as part of the unit’s design and can be refilled manually on the portable evaporative coolers. The evaporative cooling system can also be connected to the air conditioning ducts in your home and plumbed into the home plumbing to act as a regular air conditioning system. The portable coolers are available in tank capacities ranging from less than one gallon to forty gallons of water. If you consider the size of the tank, you may think that the name portable can be a misnomer because some of these portable units weigh nearly 100 pounds. However, they are mounted on wheels, and theoretically, they can be easily moved from one room to another. At least if you don’t have to lug it up the stairs.

The water tanks do have to be refilled with water after a couple of hours of work, but if you forget to refill them, the unit automatically turns into a fan, so there is no danger of any damage due to the dry tank.

Is an Evaporative Cooler Better Than a Regular Air Conditioning Unit?

The way that the evaporative cooler works makes it superior to air conditioning. For one, you can keep your windows and doors open when using the cooler. It is best to keep your windows and doors shut when using an air conditioner. Therefore, an air conditioner recycles the stale air in your home, while a cooler uses the warm air, cools it down, and blows out fresh cool air that is filled with moisture. It makes it perfect for people who suffer from asthma or dust allergies. 

The evaporative coolers are more economical. Not only is the purchase price of a unit lower than installing an air conditioner, but also the running costs are much lower. A cooler can save you up to 50% of your monthly electricity bill.

You also have more options with a cooler. You can install it into your existing air conditioning ducts, or you can use it as a portable unit that can be moved from room to room, cooling your environment wherever you are at the time. You even have the option of using it to cool just your immediate space, like a bed or a couch. The units also have modern, sleek designs that will fit in with your home’s decor.

Using only water to provide cooler temperatures is also more eco-friendly—no need for ozone-depleting chemicals used by air conditioners.

Unless you plumb your cooler to the continuous water supply, there is a possibility that the manually refillable water tank may run dry. The cooler will continue running like a normal fan without a water supply if that happens. 

The cooling units can be left on running through the night or switched off as you prefer. In contrast, the air conditioning needs to be run at all times.

Does an Evaporative Cooler Really Work?

An evaporative cooler gives as much cool air as an air conditioner. The one drawback may be that it also increases humidity in the air. If you are running your cooler in an environment that already has high humidity levels, the unit’s cooling power will be reduced. However, if you live in a dry area, running your cooler will provide a welcome relief from the oppressive heat by a lovely cool breeze and even go one better by providing extra moisture, making it easier to breathe in arid conditions.

So, yes, the evaporative cooler is a great alternative to a regular air conditioner if you live in a dry area like the western USA. It probably won’t perform as well where the weather is moist and muggy. 

To Sum Up

Evaporative coolers use the evaporation of water to cool down the ambient air. The units consist of three main parts, the water tank, the coils to evaporate the water, and the fan to disperse the air once cooled. There are many different types of evaporative coolers on the market catering to different cooling needs. While regular air conditioning units can only be run indoors, the evaporative coolers give you other options of providing air cooling capability outdoors as well as indoors. They are superior to air conditioning in many ways. The only drawback of an evaporative cooler is that for best results, it should be operated in dry climates as it adds moisture to the air while cooling it, so when there already is a lot of moisture in the air, you end up with a sticky mess.
