Cooling Systems

BuzzOFF is the leader in Georgia for Outdoor Cooling Misting Systems. We provide complete outdoor comfort for your backyard or patio.

We also install commercial cool mist systems for country clubs, hotels, golf clubs, restaurants, sports and recreation areas.

Our high-pressure mist (or fog) cooling systems can be used almost anywhere an air conditioner can be used, and many places where it can’t.

The outdoor spaces that can be cooled include residential backyards, restaurant and bar patios, sports sidelines, car auctions, construction sites, spectator cooling areas, swap meets and emergency areas. The possibilities are endless! In addition to outdoor cooling, our systems are especially capable of cooling indoor spaces such as warehouses, factories, gymnasiums, hospitality tents, stables, barns and poultry enclosures, to name just a few.

The guidelines given here are designed to help you pick the most efficient use of your machines for any given application. However, since each application is different, you will have to play with the usage of the machines to find the optimum setup. To get started, it is useful to understand the principles.

How Does Mist Cooling Work?

By forcing water through our specially designed misting nozzles, we create a fog of ultra fine water droplets with an average size of 50 microns or less. These tiny water droplets quickly absorb the energy (heat) present in the environment and evaporate, becoming water vapor (gas). The energy (heat) used to change the water to a gas is eliminated from the environment, hence the air is cooled.

Components

Mist Cooling utilizes three primary components:
• High Pressure Misting Pumps
• Fixed Line Tubing & Nozzles
• Misting Fans

Flash Evaporative Cooling and Convective Cooling
Our high pressure misting pumps and fixed line misting nozzles are designed to efficiently introduce super fine mist into the area to be cooled, which almost instantly evaporates (flash evaporative cooling). The UL-Rated outdoor misting fans are able to combine evaporative and convective cooling (wind chill factor) to
achieve spectacular results.

Employing the principles of flash evaporative cooling and convective cooling, our misting systems are effective in even the most humid environments. Cooling Efficiency Relative humidity is the amount of moisture in the air compared to the amount of moisture the air could absorb at the same temperature – this is a crucial factor in determining cooling potential. The lower the relative humidity, the more water can
be vaporized, and the more heat can be removed.

Evaporative Cooling can be used effectively in most geographical locations. This is because when temperatures reach their peak during the day, humidity is normally at its lowest point. The graph to the right shows potential cooling at different temperatures and levels of humidity. To calculate potential cooling, find
the relative humidity for the day, follow that to the curve that is closest to the outdoor temperature, and then read the potential temperature drop on the bottom line of chart. (Example: 30% humidity (a), 100° temperature (b) = 26° potential temperature decrease.)

Helpful Hints
• Whenever possible, use any natural breeze or air flow to your advantage (point the fan the same way the air is moving).
• In places where it is either impossible or un-economical to cool the whole structure or area, set up smaller cooling zones.
• In most applications, mist should be directed slightly above head level. This is especially important when using misting fans in humid environments.

Outdoor Use
The ability to cool outdoor areas depends on one major factor - the wind. With either light wind or no wind, you can achieve some remarkable results depending on temperature and humidity. Cooling outdoor areas is relatively straight forward and can be broken into two different types:
1. Getting Damp is Not OK - Hospitality Areas
When cooling a large area where the people don’t want to notice the moisture, the fan(s) should be set at their highest level with the fan aimed slightly above the horizon, with the oscillation set to match the area being cooled. If possible, place the fan 10-20’ behind the area to be cooled. This will allow the cooled air to settle and keep the unit’s sound from being bothersome.
2. Getting Damp is OK - Athletic and Amusement Cooling
In this type of cooling, the people don’t mind getting damp, and more often than not prefer to. Generally, fans are placed at head height, so people can stand directly in front of the fan. Usual Nozzle Spacing In Georgia, a more humid part of the country, is putting nozzles on a fixed line installation every three to four feet.

Indoor Cooling
When cooling indoor areas, it is important to remember that you will need to take advantage
of any natural flow of air You can check for existing ventilation by turning on the mist without the fan on and watch where the mist goes. You will also need to determine your source of outside air and where your outlet for the air is. Very often the outlet will be a door or a window on the opposite side of the structure
from the inlet air.
