Best Evaporative Coolers (2023) for hot and dry climates

1

If, like me, you often find your home too hot to be comfortable, you might find that an evaporative cooler is a good way to cool off. Evaporative coolers, which are sometimes called swamp coolers, are not the same as portable air units, despite what most people think. They work differently because they don’t have a fan and don’t need an exhaust vent. Evaporative fans work in a simple way: they pull in hot air, cool it down with ice or water, and then send the refreshed, cooler air back into the room. Even though they don’t cool as well as a portable AC unit or a window air conditioner, they are a useful and inexpensive way to keep your living space at a comfortable temperature, especially if you don’t have a lot of money or space to spare.

My own experience with an evaporative fan has been very good. An evaporative cooler helped me a lot on hot summer days in my small flat, where it wouldn’t make sense to put in a traditional air conditioner or a window unit. The device is small and doesn’t need a lot of work to set up. This makes it a good choice for anyone looking for a cheaper way to cool their home. Plus, it saves energy, which helps keep the cost of power down.

Theoretically, evaporative coolers work on the idea of evaporative cooling, which is when water takes heat from the air around it and evaporates, causing the temperature to drop. When hot air is sucked through wet pads or a water tank, the water soaks up the heat. This cools the air, which is then sent back into the room. Because of this natural way of cooling, evaporative coolers work well in dry or arid areas where humidity is low.

What is a Evaporative Coolers?

The phrases “evaporative cooler” and “swamp cooler” are frequently used interchangeably with one another. These coolers, which are also known as “desert” or “wet air” coolers, are utilized most frequently in arid regions of the world. Evaporative coolers are built to move the air through water that has evaporated throughout the cooling process. This is a frugal way of climate management that works by simultaneously chilling the space or surrounding area and adding moisture to it.

Evaporative coolers have a low impact on the environment due to their low energy consumption, which makes them a popular choice for residential use. Having one installed is an excellent way to maintain clean and cool air quality within the home, particularly while the windows are open. On the other hand, if they are not properly cleaned and maintained, they may begin to emit a smell that is reminiscent of a swamp or marsh. This problem can be avoided in part by changing the pads at least twice during the course of the season.

If you reside in an environment where the relative humidity rarely exceeds 30 percent, then an evaporative cooler can be a smart choice for cooling the space you’re in indoors. If you reside in an area that experiences humidity levels of 60 percent or less on a regular basis, an evaporative cooler might be an excellent addition to your outdoor space. It is possible that an evaporative cooler would work well in your environment, in the event that an air conditioner would not be appropriate.

Factors to Consider When Buying an Evaporative Cooler

Evaporative coolers, often known as swamp coolers or desert coolers, require careful consideration to ensure you get the proper one. Evaporative coolers operate well in dry, low-humidity conditions and are energy-efficient and environmentally benign. Key variables to consider:

• Climate: Evaporative fans work best in places that are hot, dry, and have low humidity. They work less well in places with a lot of humidity. Think about the weather where you live before you buy one.
• Cooling Capacity: Based on the size of the place you want to cool, figure out how much cooling capacity you need. Manufacturers usually say in square feet or cubic feet how much space a cooler can cool. Make sure you measure the space to pick the right size.
• Airflow and Fan Speed: Look for a model that lets you change the speed of the fan and the airflow. This lets you change how much it cools based on your tastes and the weather outside.
• Portability: Think about whether you want a movable unit or one that stays in one place. Portable coolers are easy to move from room to room, but permanent setups take more work and may need to be set up by a professional.
• Water Tank Capacity: The size of the water tank tells how long the cooler can run before it needs to be refilled. Larger tanks can keep things cool for longer without having to be refilled as often.

How to Choose the best Evaporative Coolers?

Consider various criteria while choosing an evaporative cooler (sometimes called a swamp cooler or desert cooler). Evaporative coolers are an energy-efficient and environmentally beneficial approach to cool indoor rooms, but their efficacy relies on climate, size, and personal preferences. Steps to choose the best evaporative cooler:

• Cooling Capacity (CFM): Check the cooler’s number for Cubic Feet per Minute (CFM). If the CFM is higher, the fan moves more air, which can cool a bigger area well. Match the CFM to the size of the room you want to cool.
• Water Tank Capacity: Think about the size of the water tank. A bigger tank may mean that you need to fill it up less often, but it can also make the unit bigger. Choose a tank size that fits how much you use it every day.
• Energy Efficiency: If you want to save money on power costs, look for a model with a high Energy Efficiency Ratio (EER).
• Noise Level: Check the unit’s noise level, especially if you want to use it in a bedroom or other quiet place.
• Additional Features: Some evaporative coolers have extra features like remote controls, timers, and fans that can run at different speeds. Think about the features that are most important to you.
