Patio Cooling for Memorial Day

Pool deck with an outdoor evaporative coolerHappy Memorial Day weekend everyone! It’s an exciting time around here, because it’s officially the start of Summer BBQ season!

While we’ve talked a lot about using our misting fans outside on your patio or pool deck, did you know that an evaporative cooler can also be a great outdoor cooler? They’re particularly useful for parties. Unlike misting fans, which spray a water mist – albeit a dry one – evaporative coolers only blow cold air. This makes them a great option when you’re looking for cooling, but would rather not have any mist.

Our Luma Comfort units are also portable, so they’re easy to move around for short term events – like your Memorial Day BBQ!

So this weekend try out your swamp cooler on the patio and let us know how it goes!

Easy Homemade Evaporative Swamp Cooler

Granted, this is not going to provide the same type of cooling power that you’d see from one of these, the idea is the same – as water evaporates, it pulls heat from the air. All you need to do is then circulate that cooler air throughout your room, and BAM, you’ve got yourself a swamp cooler. Sounds simple, right?

There’s a good chance you have everything you need to set up a primitive evaporative cooler right at hand: a fan, a shallow container, and some water.

To re-create this cooler, all you need to do is set up a shallow baking pan, filled with water, in front of a basic window fan.

The idea is that the air flowing from the fans will evaporate the water and cool down the room.

Obviously, the same limitations of normal evaporative coolers apply to homemade coolers, sometimes even more so. For instance, they will undoubtedly work best in very hot, dry environments. That said, this author was able to lower the temperature in his office by 7 degrees. Not bad at all!

Does An Evaporative Cooler Work In My Area?

Hot Summer Sun at the BeachIn short, yes!

The real question, though, is: How effective will an evaporative cooler be in my area?

Evaporative coolers, also commonly called swamp coolers, use the power of evaporation to cool the surrounding area. These air coolers typically consist of a fan and a water-soaked pad. As air passes through the pad, the water evaporates, which draws heat from the air. This cooler air is then re-circulated through the room. Being such simple machines, evaporative coolers are generally less expensive than air conditioners. They also use much less electricity to operate – making them an economical and environmentally friendly alternative to air conditioning.

As a result of their cooling process, evaporative coolers also add moisture and humidity to the air. While this is beneficial in dry climates, it also means that evaporative coolers are not as effective in more humid climates.

Typically, evaporative coolers work best in areas in areas that are very dry, as well as hot. A perfect example is the Southwestern US, including parts of Nevada, Arizona and New Mexico. In these desert climates, not only are the summer months hot, but they are also quite dry.  Evaporative coolers can be just as effective as air conditioners in these areas- but at a fraction of the cost.

Evaporative cooler climate is not limited to this area, either! Throughout the US, many major cities have great climates for air coolers – including Denver, Salt Lake City and even San Francisco.

When trying to decide if an evaporative cooler will be effective your area, first look at the humidity level. Generally speaking, the lower your relative humidity, the more effective your evaporative cooler will be. The map below shows general areas in the US where evaporative coolers are most effective. Areas labeled “A” are optimum for evaporative swamp coolers, while those labeled “B” are less than ideal, but can still be good.

Areas like the East Coast are unfortunately less than ideal conditions for an evaporative cooler. Evaporative coolers can still be useful here, however! Units like our EC45S Tower Cooler can act as a simple tower fan or even a humidifier, making it very useful – even on the East Coast.

The below chart shows the estimated temperature change you can expect from an evaporative cooler, depending on the relative humidity and current temperature. Just note that this assumes you have the proper size evaporative cooler for your room.

Using the above, you should be able to come to a pretty good conclusion about whether or not an evaporative cooler will work in your area. If you have any questions about evaporative coolers and your climate, let us know!
