Evaporative coolers are most effective in high temperature (85°F or more) and lower humidity (below 50% relative humidity) situations. Evaporative coolers are least effective in lower temperature (below 75°F) and high humidity (above 60% relative humidity) situations.
Do evaporative coolers work in humid areas?
Evaporative coolers should not be used in humid climates because they add humidity to the air in your home. Also, they do not cool your house down as low as an air conditioner would, and they require simple maintenance about once a month.
At what humidity does a swamp cooler quit working?
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.
Will a swamp cooler work in 50% humidity?
The higher the humidity, the less effective evaporation will be as a cooling method. For example, while the air is at 10% humidity, the swamp cooler can drop temperatures by up to 20 to 30 degrees, while at 50% humidity, the swamp cooler can drop temperatures by about 10 degrees.
Do swamp coolers work in 40% humidity?
This is the temperature you can expect to achieve with your evaporative cooler. For example, if it’s 85 degrees and 40 percent relative humidity where you are, you’ll see that you can bring your temperature down to 72 degrees with an evaporative cooler. That’s ideal for comfort!
Will an evaporative cooler work in 70% humidity?
Evaporative coolers are most effective in high temperature (85°F or more) and lower humidity (below 50% relative humidity) situations. Evaporative coolers are least effective in lower temperature (below 75°F) and high humidity (above 60% relative humidity) situations.
How can I make my evaporative cooling more effective?
5 Ways to Optimize Your Evaporative Cooler’s Performance
- Choose the Right Time of Day.
- Clean and Replace Cooling Pads As Needed.
- Keep Your Unit Clean.
- Maintain the Correct Water Level.
- Run the Unit Smarter Instead of Harder.
How many windows should be open for evaporative cooling?
Most experts recommend that you open windows which are furthest from the ducts or vents. You should aim to create an opening twice the area of the vent opening.
Why evaporative cooling does not work in high humidity?
The System
When the water in the air matches the water in the pads, then no cooling can take place. In other words, these machines rely on water in the air. If there is too much, like there is in humid weather, then cooling is less or nonexistent. Even for areas with normally low humidity, this can still be a problem.
How do I lower the humidity in my house with a swamp cooler?
Open the Windows
As you run a swamp cooler, it makes moist air in your home as water evaporates into the air. However, the more humid the air in your house is, the less effective your evaporative cooler will be. To solve this problem, keep a few windows cracked to let dry air in and damp air out.
When should you not use a swamp cooler?
They have a hard time cooling your home when it gets above 95 degrees. They should not be used when the climate is humid as they use humidity to cool a home. They do require more maintenance from a traditional central air conditioner. They are prone to leaks due to float problems.
Is 50 too much humidity?
A humidity level no higher than 50% is optimal as a general rule of thumb, but the best level depends on the temperature outside. The level of humidity, whether outdoors or inside your home, is a big factor in your comfort level and is a factor in your overall health.
What is the best humidity for air cooler?
The ideal humidity level for an evaporative air cooler is below 60% humidity. You can also make it more efficient by improving air circulation and aeration, as well as keeping the doors and windows open.
Does a swamp cooler work better in the sun or shade?
I’m wondering if a cooler – the old-fashioned swamp cooler, evaporative cooler – works better in the sunlight or in the shade? TOM: Well, it certainly would work better in the shade. You’re going to get better cooling action without having the added evaporation of all of that direct sunlight on the water.
Why is my swamp cooler not getting cold?
Air is not cool: If your cooler is not blowing cold air, it is likely due to the water system. If the pads are not sufficiently soaked, it is impossible for the cooler to create cold air. Check the pads to see if they still retain water, and if they are new or functioning properly, move on the water pump.
Do evaporative coolers work in dry climates?
Also known as evaporative coolers, these are earth-friendly, affordable cooling options. Most effective in dry climates where humidity is 60% or below, they pull air over saturated rigid cooling pads that can reduce your room temperature up to 20 degrees.
How long do evaporative coolers last?
But, while swamp coolers don’t cost much to buy, they are a lot of work and money to maintain. Not only that, they are only warrantied to work for 5 years. Refrigerated air systems can last up to 20 years if properly maintained.
How often should evaporative cooler dump water?
every 6-12 hours
If your evaporative cooler has a dump style drain valve, the water will be dumped every 6-12 hours (depending on what your coolers setting is) and then again after it has been turned off. This controls the quality of the water that is being used. Your evaporative cooler may have a leak.
Do evaporative coolers actually cool a room?
According to the US Department of Energy (DOE), an evaporative cooler can successfully reduce the ambient temperature by 5 to 15 degrees—but even the DOE is quick to clarify that this process works only in areas with low humidity.
Do evaporative coolers use a lot of electricity?
How much energy does an evaporative cooler use? Power use is generally low (200 to 400 watts) because only the fan and water pump use energy. But this can vary widely depending on features and capacity, and there are domestic units that draw up to 2kW or more.
Where is evaporative cooling the most effective?
Evaporative cooling is most effective in areas of the US where the climate is dry, and hot and humidity is low during summer. This includes most parts of the western states.
