How Does an Evaporative Air Conditioner Work?

December 1, 2021 10:00 am Published by Leave your thoughts

An evaporative cooler works differently than traditional air conditioning systems with ductwork. Commonly called a swamp cooler, these coolers work by embracing the process of evaporation.

The Process of Evaporation

Evaporative coolers use the process of evaporation to create cool air that increases the level of humidity in the air. There are a few important components of this cooler:

  • Fan
  • Thick pad
  • Water reservoir

The fan is responsible for drawing the dry, hot air into the machine and across the thick pads that are soaked with water. As the pads absorb the water from the reservoir, they are ready for the hot air. The air crosses the pad, collecting water molecules along the way. The water evaporates and causes the temperature of the air to drop. Often, the temperature can drop by 20 degrees or more.

As the fan blows the cold air, you enjoy the comfort that is offered.

How You Can Regulate an Evaporative Coolers

You have the ability to control various aspects of the evaporative air cooler. You will be able to control the temperature and the humidity. Simply opening windows can help to move air around more effectively. Additionally, you will have ways to control the speed of the fan as well as the openings to control how much air is flowing through the system.

Additionally, there are filters that you can buy for some evaporative coolers. These can help to remove dust and other allergens. If you or those around you suffer from allergies, you can help to control the allergens that flow through the air.

Why Evaporative Coolers are Beneficial

You’ll quickly find that because evaporative coolers work without a lot of fancy technology or ductwork, they are going to be your most affordable option. They don’t require a significant upfront investment and they don’t require a lot of maintenance from year to year.

Additionally, you’ll find that there aren’t going to be a lot of energy requirements to keep an evaporative cooler operating efficiently.

Beyond the cost savings, you’ll love that the added humidity can help. When you live in dry conditions, you often experience dry skin, sore throats, and even itchy eyes. The added moisture in the air will help to clear up those conditions, helping you to feel healthier.

Types of Evaporative Coolers

There are a few different types of evaporative coolers available. You can find ones that are installed on walls, roofs or are even portable. Models vary in size to accommodate residential, commercial, and industrial needs. Whether you want a cooler to cool a single room or an entire warehouse, there’s a unit that will work effectively for you.

When you begin working with a professional, they work with you on the sizing and selection of a cooler. The professional should be looking at the cubic feet per minute so that you get the right amount of air delivered to the space.

Additionally, the manufacturer should also help you with how it’s going to be installed. If you already have ductwork in place, an evaporative cooler can be connected. This way, you get help distributing the humid air to different rooms.

As you discuss your needs with a cooling professional, they can guide you toward a system that will offer the most efficiency as well as the level of humidity that your space demands.
