Evaporative Cooler vs Air Conditioner

The benefits of different air cooling systems and their use have been a long-running topic of HVAC experts. Nowadays, however, due to rising utility bills, shrinking resources for energy, and environmental issues alternative cooling methods are at the forefront of the field.

Although many of us may not be working in environments where air conditioning is not practical in the real world, millions of people – including those working in construction, agricultural automobile, industrial and warehouse industries are at risk of suffering from heat stress every day. All of them deserve an environment that is safe and comfortable.

The Differences Between an Evaporative Cooler and an Air Conditioner

In general, air conditioners employ refrigerants to eliminate heat and moisture from a room. They make use of a fan to spread the conditioned air to improve the comfort of indoors and improve quality.

They are typically fixed, ducted systems that require at least bi-annual maintenance by a qualified professional to perform optimally.

In this kind device, the air gets chilled in coils using chemical methods and then the heat and moisture is emitted outdoors. Air conditioners are best suited to completely enclosed spaces and are able to lower temperatures to a specific desired ambient temperature regardless of the weather conditions.

The main drawback of the systems is their cost and installation costs. Not only does it cost thousands of dollars upfront monthly operating costs could be in the hundreds.

Differences Evaporative Air Cooler vs Air Conditioner

Evaporative Cooling Systems

The cooling system that is evaporative sometimes called “swamp coolers” require less materials to run – usually just electricity and water. They typically need less care than ACs, and could result in significant savings over an entire year. Although evaporative coolers use water to cool themselves however, they don’t produce any fog, mist or spray water.

Energy Efficiency

Evaporative Air Coolers are a more efficient. They consume between 15 and 35 percent of the power required by an air cooling unit similar in size, and do not require any chemicals. However, they do require a continuous supply of water. In regions of water shortage or shortage, they could be less effective. They might also not provide the same cooling effect as an air conditioner under all conditions.

Portable Evaporative Coolers for Air

Evaporative coolers make use of some kind of water-soaked material that can be pulled by air using the fan. When air is pulled into the media, it reacts with the water, and heat molecules are removed from the air, resulting in cooler and slightly dampened air.

They are most effective in open spaces, and with ample access to fresh air. Evaporative coolers are not often employed in enclosed areas. Additionally, the reduction in temperature is not a choice, and is determined by the ambient conditions.

Although the fixed systems for evaporative cooling may be more costly to set up (most portable evaporative coolers come available right out of the box) operating costs are very low – sometimes as little as $1 per day, making them more efficient in energy usage than air cooling.

Is evaporative cooling the right choice for you?

There are a variety of factors to take into consideration when selecting cooling systems for buildings or even for outdoor usage. One of the primary – and most crucial – factors to consider is whether the area has access to fresh air or is closed.

For instance, if you work in a warehouse and the doors are opened for most of the time cooling isn’t an option that is viable, since you’re letting all the air that you have paid for to cool escape.

But, if you’re working in an office environment in which windows are closed and doors remain closed the evaporative cooling method isn’t likely to be very effective and could create a more uncomfortable environment because it adds too much humidity in the air.

To dispel a myth many people will claim that evaporative cooling is only effective for dry environments. Although evaporative coolers can achieve significant temperature reductions in dry climates and in more arid regions however, they are able to offer relief from heat of any climate thanks to advancements in the field of evaporative cooling.


Is it cheaper to run a swamp cooler or air conditioner?

In general, swamp coolers do cost less to run that conventional central AC.

Can a swamp cooler cool an entire house?

No, an evaporative cooler, aka swamp cooler will not cool and entire house.
