When it comes to evaporative cooling systems, the question of whether you will need an open-air source or a closed-loop system is not a simple one. If you are planning on using an evaporative cooling system for your home or business, you need to consider this question when making the decision.

What is Evaporative Cooling?

Evaporative cooling is the process of removing heat from the air through evaporation. This natural process occurs when water evaporates from ponds, lakes, and streams. For this process to occur, there must be a large body of water and an area with a high humidity level. When these two conditions are present, the water molecules become saturated with energy, which causes them to leave the surface and enter the surrounding atmosphere. The energy once contained in these water molecules is now available for use by other forms of life in their environment.

Do You Need an Open-Air Source for Evaporative Cooling?

The answer is yes. Even if you have an open-air source for evaporative cooling, it’s still essential to provide a method of covering the water and keeping it from evaporating too quickly.

The most efficient way to do this is with a solar cover. This can be a sheet of plastic or some other light material that will allow the water to be contained in its little pool but still allow the heat from the sun to heat the water and make it evaporate more efficiently.

A solar cover can also increase your efficiency by creating a closed system where there was none before. This is because the water coming in through your skylight is also heated by sunlight. Still, because it comes through two different types of materials (the skylight and the solar cover), it isn’t fantastic, as if you had just one of those two materials instead of both together.

If you are worried about how much space you need for an open-air source for evaporative cooling, don’t worry! You don’t need much space at all. You can use any type of container that holds water and will allow sunlight into it without letting out any heat from inside or out.

Evaporative Cooling: How It Works

Evaporative cooling occurs in a closed system with one air intake and two air exits. The air that enters the system passes through a wetted surface before exiting at the other end of the system.

The first step is to collect water evaporated by sunlight or another heat source. Typically, this is done by installing a reservoir in your yard or garden where you can collect rainwater or snow melt during the winter months. The water should be stored in an insulated container to prevent freezing during cold weather.

Next, you will need to connect your open-air coolers to your home’s HVAC system using supply and return ducts. The supply ducts go from your collection tank into your home, while return ducts carry air back into the outdoors after it has cooled down inside your home.

For best results, you should install an outdoor unit near the highest point in your yard or an opening in your roof line, and make sure you get a unit from a tried and tested company like Premier Industries.

Evaporative Coolers Need Hot Air

Open air coolers are a great way to keep your home cool without electricity.

The problem is that most evaporative coolers don’t have enough hot air to do their job correctly. This is because they are designed to be used with hot water, but most of the time, you’ll need hot air from somewhere else to get them up and to run.

This is where an electric fan comes in handy. Electric fans can generate all the hot air you need, so you won’t have to worry about running out of steam before your evaporative cooler gets going.

Evaporative Coolers Benefit from Dry Air

Open air coolers are a great way to cool your home during the summer. They use evaporative technology, which removes moisture from the air and converts it into water vapor. The water vapor is then released through a fan, cooling the surrounding area.

The amount of moisture in the air can affect evaporation rates, so it’s crucial to measure humidity before installing a new evaporative cooler accurately, and this can be done with the help of a professional company.

Applications that are great for Evaporative Coolers

Evaporative coolers are ideal for any home or office space that needs cooling. Portable evaporative air coolers lightweight and easy to set up.

The evaporative air conditioner is also ideal for outdoor use in areas where it gets hot and humid during the summer months.

Tips on How to Use Evaporative Cooling Properly for Optimal Performance

Here are some tips on how to use open air coolers properly to ensure optimal performance:

  • Using a pool cover
  • Set the right humidity level
  • Make sure that your filter is clean
  • Boost the airflow in your home
  • Use natural ventilation
  • Keep up with maintenance
  • Turn it on before you go to bed
  • Keep windows and doors closed
  • Use the cooler when there is minimal to no wind

Benefits of Evaporative Cooling

Here are some of the expected benefits of utilizing evaporative cooling:

Energy Cost Savings

Evaporative air coolers are a great way to reduce your energy bill. They only use water and have no moving parts, so they don’t use any electricity.

Open air coolers work by sucking in cool air through the top of the unit, then passing that air over a wet pad of cloth that absorbs the moisture from the air. The moistened cloth acts as a sponge and draws heat from the air. This process is called evaporation because it’s similar to how water evaporates when it’s cooled by air. When you turn off your evaporative cooler, the moistened cloth will absorb any remaining moisture before it can escape into your home or the atmosphere.

You can save up to 50% on your energy bill when you install an evaporative cooler.

Simplicity of Installation

The installation process by a company like Premier Industries Inc. for an evaporative cooler is simple, but some tips can help make it easier:

  1. Ensure your home has enough ventilation before installing an evaporative cooler. The cooler will need somewhere to expel moisture, so if you have poor ventilation (such as when you’re using a window unit), you’ll need to install vents on windows or walls that can be opened when using the cooler.

Enhanced and Improved Comfort

The most apparent benefit of open-air coolers is enhanced comfort for those in hot climates or climates that don’t have proper ventilation, like Phoenix, AZ. In addition, this type of cooling will allow you to stay cool without relying on air conditioning, which can be extremely expensive in some areas.


If you want a refreshing home without the high price tag of traditional air conditioning, then evaporative cooling is something to consider. This technology offers a host of perks, including greater energy efficiency than the ceiling or portable air conditioners. However, if you live in a humid climate, you’ll want to exercise caution before buying an evaporative cooler.
