How Does It Work?

Cool-n-Save® is an AWARD WINNING patented product that is simple to use and install.

Anyone can Install a Cool-n-Save® residential DIY kit in less than five minutes with no tools required. The valve housing affixes to the top of most home air conditioning units. It activates only when the AC unit turns on; hot air from the condenser unit’s fan raises the flap on the patented Cool-n-Save® control valve allowing water to flow to the misters that surround the AC unit. When the ultra-fine mist is released into the air, it evaporates almost instantly creating what is known as a “Flash Evaporation,” which literally sucks heat out of the air as water absorbs the energy it needs to evaporate. The result of the immediate evaporation constitutes a substantial drop in ambient temperature without wetness—up to 30 degrees Fahrenheit.

Cool-N-Save was tested by Tulane UniversityWe won the 18th annual TechAmerica/Harvey Mudd High-Tech Innovation Award for Green Engineering in 2011 in recognition for our work with energy-saving evaporative pre-cool misting technology for commercial and residential central air conditioning systems. We have worked for the last five years to offer Americans another way to reduce energy consumption and cut carbon output – safely, inexpensively and effectively. We developed Cool-n-Save to be cost-effective and practical. See this video.

Air Conditioning 101

The typical Air Conditioning system consists of evaporator coils, a fan inside, a compressor, compressor coils, and a fan outside. The unit cools by using the refrigerant, usually Freon, to transport the heat from inside the space to the outside air. The heat is expelled into the outside air by the action of the fan pulling air over the coils and the heat contained in the refrigerant is transferred to the air.

The Heat Problem

The problem with the AC system is that in extreme heat, many conventional air conditioners are unable to effectively transfer their stored heat into the surrounding air. They are forced to work harder and longer to cool the air in your home, shortening their life and producing unreasonably high electric bills.

To combat this problem, large commercial AC users such as commercial factories, warehouses and office buildings have been installing professional misting systems around their AC condensers for years. These misting system are much like the misters you may have encountered in restaurant patios and amusement parks. Greenway Design Group, Inc., inventors of the Cool-n-Save® System, have actually designed and installed many of these industrial systems.

The Magic of Mist

When ultra-fine mist is released into the air, it evaporates almost instantly. This "flash evaporation" literally sucks heat out of the air, as the water absorbs the energy it needs to evaporate.

This process, called "adiabatic saturation," is a well-known scientific principal that has been used for years to lower air temperature in outdoor zones.

The result of this constant, immediate evaporation is a substantial drop in ambient temperature without wetness. The air temperature near a misting system is automatically lowered by as much as 30 degrees.

The Breakthrough

The problem with existing industrial AC misting units is that they are large, complex systems that need to be professionally installed. They rely on electrical solenoids and switches to send water to the misters only when the AC condenser is running. Most homeowners cannot afford to have such a costly commercial grade system installed for them. Once installed, for the average homeowner, they are complex to operate and difficult to maintain - requiring continued maintenance on electrical components.

The Cool-n-Save® breakthrough is its patented control valve, which easily installs to the top of virtually any AC condenser. When the AC unit turns on, it triggers the valve open and filtered water flows to the misters. When the AC unit shuts off, the control valve immediately closes and no water is wasted.

Cool-N-Save's brilliance is in its simplicity. Cool-N-Save® is designed to quickly install on virtually an AC condenser with no tools. No electricity is needed to power the Cool-n-Save™ system, and no complex connections or diagrams need to be followed.

Finally, the scientific principal of energy efficiency used for years by large corporations to save money, can be applied to almost any home AC system.

Saving you Money

When applied to your AC condenser unit, the Cool-n-Save® creates a "Chill Zone" which keeps the air around your unit up to 30 degrees cooler than the surrounding air. Because of this, your AC unit can transfer heat much more efficiently, greatly increasing its EER (Energy Efficiency Rating.)

This increased energy efficiency saves you money in two ways. First, the lower temperatures in the AC compressor itself means it runs at a lower pressure, allowing it to work using less energy. Second, your AC unit will run for shorter periods since it will transfer heat much more efficiently. This results in your AC unit using much less electricity, lowering your summer cooling bills!
