Portacool Evaporative Cooling | Portable Evaporative Air Coolers

What Is Better – Swamp Coolers or AC?

It’s spring, and across the country, temperatures are already spiking. It’s time to start thinking about cooling solutions to make it easier to work, play, and just live when the air gets hot outside. The two leading solutions for your home, work, or outdoor areas are evaporative coolers (sometimes referred to as swamp coolers) and air conditioning (AC). But which is better?

The better choice depends on your situation. In some cases, swamp coolers are better. In other cases, AC is a better choice.

When Swamp Coolers Are Better

Swamp coolers work by using the natural process of evaporative cooling. It takes a lot of energy for water to evaporate, and when that energy comes from the air, the air cools as much as 30° F. Since this energy comes from the hot air, swamp coolers are highly energy efficient. The only energy the cooler uses is to run the fan.

Swamp coolers are better when:

Swamp coolers use hot air to cool. It sounds like a paradox, but it’s true. That means you need to have access to hot air to make a swamp cooler work. Fortunately, in summer there’s no shortage of that!

Large evaporative coolers like the Portacool Jetstream 270 can cool more than 22,000 cubic feet of air per minute. That’s a volume of air 20 feet wide by 100 feet long by 11 feet high every minute. At that rate, it won’t take long to cool even the largest spaces.

Swamp coolers work best when the air is dry. It’s easier to evaporate water when the air is dry, so the cooling effect is better. Swamp coolers work when it’s humid, but they work better when it’s dry.

Because swamp coolers are constantly cooling new air, they don’t depend on being able to re-cool already cooled air. This makes them perfect for cooling when you can’t seal off the area to be cooled, such as when you’re working outside. They also work well if you’re trying to keep an area well-ventilated as well as cool.

Swamp coolers are extremely energy efficient. Remember, much of the power for cooling comes from the hot air. You’re only running electricity to operate the fan circulating the cool air throughout your space. They use less than ¼ as much power as an air conditioner.

Saving energy means saving money. Highly efficient evaporative coolers like Portacool can provide cooling for an entire workday for less than $1 per day.

When AC Is Better

Sometimes, though, AC is a better choice for cooling. AC works by compressing a coolant to drop the temperature, using that coolant to cool the air, then letting the coolant expand and get hot, passing heat to the outside air. It’s an energy-intensive process that exports a lot of heat to the outside air, but it’s very effective.

You might choose AC when:

AC works best when it is cooling a small space. This lets it concentrate the cooled air. Also necessary for AC is that the space is well-sealed so the AC can cool the air in multiple passes.

AC has the side effect of removing moisture from the air. It is the best choice when you are trying to dry the air as well as cool it. Another benefit of AC is that after repeated passes of cooling, it can reach essentially any temperature you desire. This makes it the right choice for cooling spaces where you must achieve a very low temperature.
