For many years American Indians and desert dwellers used burlap cloth soaked in water over windows and doors to cool their houses. This was one of the first practical applications for Outdoor Cooling to help residents survive the harsh temperatures and live comfortably in the desert. In the Arabian deserts windcatchers or malqafs used similar principles of evaporative cooling to make buildings habitable through the summer.
In today’s modern world MicroCool uses the same principle of evaporative cooling to reduce temperatures for patios, hotels, sports fields and private residences all over the world. When water flash evaporates into the air (or changes state from a liquid to a gas), the air around is cooled and the humidity is slightly increased. Theoretical temperature reductions of 35°F or 19°C are often quoted, however the reality is that reductions of 15 – 20°F and 10- 15°C without wetting and increasing the humidity beyond a comfortable level are more the norm.
By forcing water through custom MicroCool nozzles with a 0.20mm orifice, the water is exploded into billions of small droplets each increasing the surface area of the water by a large percentage. Much the same as when you feel cold after swimming as the water evaporates from your skin, so does the air temperature around the droplet fall rapidly. The more water forced into the air increases the humidity until the evaporation rate slows and the air cannot accept more water. This is when wetting occurs from badly designed and controlled systems.
Low pressure nozzles, large droplets and similar systems do not produce small enough droplets to “float” in the air and often result in the users and surroundings getting wet without any cooling benefit.
For over 30 years MicroCool has designed, built, installed and maintained outdoor cooling systems for sites all over the world. In recent years many companies have appeared making exaggerated claims and promises that are way beyond the physical possibilities of even the most efficient system. Using low cost, imported equipment the market is awash with imitations.
MicroCool engineers design and study each application to ensure that it is correctly laid out, fits the environment and most importantly, the client’s needs. Designers select the correct equipment, suggest the best pump location, nozzle line height and spacing and offer control points before presenting the layout to the customer. Options regarding water treatment, controller use and maintenance are explained to the client at every step of the way.
Using new motor drive technology, MicroCool systems can use up to 50% less electricity than standard pump units. Quieter, more compact pumps can be mounted closer to cooling areas and are much less intrusive. American made nozzles with integral filters are designed to last longer and give a more consistent delivery than other imported models.
