Do portable evaporative coolers work in humid climates?

Portacool evaporative coolers CAN drop the air temperature up to 30°F when the air is very dry such as arid climates of the Southwest where relative humidity is typically 30\% or less. That said, even in hot and humid areas such as Houston, you can still expect to achieve a 10°F-13°F drop in temperature.

What climate is best for evaporative cooler?

The answer is that a swamp cooler is right for the exact opposite of a swamp: it’s right for a dry, desert climate. The reason that swamp coolers are a good match to low-humidity areas like Phoenix is because they work through the principle of cooling the outside air by moving the air across water-saturated pads.

Do evaporative coolers work in dry climates?

The evaporative cooling process requires only a small fraction of the energy that air conditioners use. The heat transfer is accomplished through the physics of evaporation, rather than by compressing liquid refrigerant into a smaller space and then moving it across a heat exchanger.

What do you do with an evaporative cooler in the winter?

How to Winterize your Evaporative Cooler

1. Turn Power Off. First, turn the power supply off on your unit.
2. Turn Water Supply Valve Off. In order to keep the pads inside of the unit wet, the cooler needs a water supply valve to bring water into the unit.
3. Drain the Swamp Cooler.
4. Cover the Unit.

At what humidity does a swamp cooler work?

Swamp coolers work in humidity up to about 70 percent. However, you may begin to feel muggy before the air reaches this saturation with or without a swamp cooler.

At what temp do swamp coolers become ineffective?

According to USA Today, “When the outside temperature soars to 100 degrees (38 C), we’re in trouble if the humidity is much above 25\%.” As temperatures rise, humidity must decline in order to effectively cool your home.

Do you have to winterize a swamp cooler?

While this equipment has few maintenance needs, keeping it operating efficiently requires an annual winterizing process. This helps prevent the water line from freezing and minimizes damage from condensation and rust. It also helps prevent heat loss through the cooler’s vent.

When should you winterize your swamp cooler?

Should you wait until the weather drops to a certain temperature? Typically, you should start thinking about turning off your swamp cooler and turning on your furnace when the nights drop below 50° and days are in the low 70°’s.

Do swamp coolers work over 100 degrees?

Here’s the deal: your swamp cooler will only cool your home by about 10 degrees. In addition, it will struggle immensely, and likely will not work at all, when its humid outside. However, it will do a better job of cooling, and in humid weather your refrigerated air system will cool and dehumidify.

Do evaporative coolers work in swampy areas?

Despite their nickname of “swamp cooler,” evaporative coolers are actually useless in swampy, humid areas. Portable air conditioners are a smaller version of a central air unit — only all of the parts are contained in one space, rather than most of the unit being outside.

How can I Make my swamp cooler more efficient?

By the same principle, it can also give your swamp cooler a big boost in efficiency. For best results, place your dehumidifier near your evaporative cooler ’s air intake grill. This will help make sure that the driest possible air flows across the cooling pads for excellent evaporation. 5. Cultivate a Green Thumb

What happens to a swamp cooler in high humidity?

The same thing happens with an evaporative cooler: High humidity levels make it impossible for the swamp cooler to work well because the water just can’t evaporate quickly enough to bring down the air temperature.

Do evaporative coolers work as well as air conditioners?

Under dry, hot conditions, an evaporative cooler can work just as well as a refrigerant-based air conditioner. For example, on the day we’re writing this, relative humidity is at 14\% and the temperature is in the mid-80s. Under these conditions, an evaporative cooler can lower the temperature down to the low 60s!
