We can all agree that feeling hot is uncomfortable. It makes it nearly impossible to focus, and there is only so much you can do to keep cool. This discomfort is often due to the fact that many homes and businesses rely on outdated refrigeration-based air conditioning units to beat the heat. But, if you want to maintain healthy indoor air quality, save money, and keep cool, an evaporative cooling system may be the solution for you.
What is Evaporative Cooling and Hybrid Air Conditioning?
Even if you have never heard the term before, you likely already know how evaporative cooling works. Think about all of the times you have gotten out of a swimming pool on a hot day and felt chilled. You felt cold because the warm air around you was evaporating the water off of your skin.
Commercial grade evaporative cooling works the same way. Hot air from the outside is passed through a moist media, evaporating the water and cooling the air. That freshly cooled air is then circulated through the building.
However, sometimes the outside air is too humid for an evaporative cooling system to work effectively. A smart hybrid system senses outside conditions and automatically switched from an evaporative cooling system to a traditional refrigerant or chilled-water cooling coil to keep the structure comfortable.
How Much Moisture Does Evaporative Cooling Add to the Air?
Many years ago evaporative coolers were nicknamed swamp coolers because of all of the humidity they added to the air. However, modern evaporative coolers only add a fraction of the humidity to the air, while providing significantly better cooling results than the older systems.
Today’s commercial grade evaporative coolers do not add noticeable amounts of moisture to the air inside of a building.
When using a cutting-edge evaporative cooling system or a hybrid air conditioning system, most people will not even notice any increase in the internal humidity levels.
Why Air Circulation is Critical for the Health of your Building and the People Inside
In office buildings and residential spaces, keeping the air comfortable is only part of the battle. It is also critical for the health of the building and everyone inside of the buildings that the air be properly circulated and that fresh outside air be brought in.
The air quality inside of most buildings is significantly worse than the air quality outside. Stale air allows environmental hazards to fester. Things like mold, pollen, and bacteria flourish in the staid, dry air produced by traditional air conditioners.
This can cause serious health problems for the people in these spaces and can create maintenance problems for the air conditioning units and the ductwork.
An evaporative cooling system brings in a regular supply of fresh outdoor air into the building as part of the cooling process. This flushes out many of the environmental toxins and keeps them from getting a foothold inside of the building infrastructure.
These systems not only keep everyone cool, but they also help keep everyone healthier.
Understanding the True Link Between Heat and Humidity
One of the biggest worries people have about evaporative cooling is how effective they can be in a humid climate. Even in the most humid parts of the United States and Canada, evaporative cooling systems can still be an effective way to cool a building.
Similar to how the temperature fluctuates during the day, so does the humidity level. During the hottest part of the day, the humidity level actually drops. This creates enough of a differential between the temperature and the humidity level for an efficient evaporative cooling system to effectively cool even a large space or building.
However, if you want to keep a building as comfortable and healthy as possible, your best choice is a smart hybrid air conditioning system. A smart system constantly monitors the outside conditions and can automatically switch to the most effective cooling method based on the external conditions. This means that you get all of the benefits of fresh air and evaporative cooling without having to sacrifice your comfort. During the most humid parts of the day, a smart hybrid until will switch to a traditional air conditioning cooling method until the humidity levels drop enough for the evaporative cooling system to be effective.
Hybrid air conditioning systems that make full use of cutting-edge technologies and the principles of evaporative cooling are the best way to create a comfortable, healthier internal environment.
