Air Conditioning 101
The efficiency of air conditioners has increased steadily since the 1970s. The 1987 National Appliance Energy Conservation Act authorized the Department of Energy to set minimum efficiency standards for space conditioning equipment and other appliances each year, based on what is "technologically feasible and economically justified".
Despite a number of technological improvements, many American lifestyle changes have put higher demands on cooling resources. In 1978, 23% of American households had central air conditioning. By 2001, that figure had climbed to 55%. It is even higher today. What’s more, the average size of homes built in the United States has increased significantly, from 1500sqft in 1970 to 2300sqft in 2005.
These energy demands are further compounded by large or over-sized air conditioning units often installed by contractors "in order to avoid complaints, accommodate future expansions, enable quicker cooling down of homes, and to allow for lower cooling set points by homeowner". This common practice can drastically increase your cooling costs as a trade-off. Cool-N-Save™ is an inexpensive solution to an expensive problem. Cool-N-Save™ can reduce your air conditioning costs by up to 30%.
The Cool-n-Save has been designed to work with Central Air Conditioning units. Central air conditioning systems use ducts to distribute cooled air to more than one room or use pipes to distribute chilled water to heat exchangers in more than one room.
With a typical system, the condenser and compressor are located in an outdoor unit and the evaporator is mounted in a separate air handling unit (which is often a forced air furnace). Some systems are not split like this and have all of their components located in a single outdoor unit which may be located on the ground or roof.
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 a liquid refrigerant to transport the heat from inside your home or office to the outside air. The heat is released into the outside air by the action of the fan pulling air over the coils; the heat contained in the refrigerant is transferred to the air.
The Heat Problem
The problem with air conditioning systems 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, which shortens their lifespan and produces unreasonably high electric bills as a result.
To help alleviate this problem, large commercial A/C users (commercial factories, warehouses, office buildings, etc.) have been installing professional misting systems around their A/C condensers for years. These misting systems are much like the misters you may have encountered in restaurant patios and amusement parks.
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 principle 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 air temperature without wetness. The air temperature near a misting system is automatically lowered by as much as 30 degrees.
The Cool-n-Save Breakthrough
The problem with existing industrial A/C 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 A/C condenser is running. Most homeowners cannot afford to have such a costly commercial grade system installed for them. Plus, their complex electrical components require continued maintenance, making commercial systems too difficult for most homeowners to operate and maintain.
The Cool-n-Save breakthrough is its patented control valve, which is easily attached to the top of virtually any A/C condenser. When the A/C unit turns on, the moving air lifts the paddle and opens the control valve allowing filtered water to flow to the micro water misters. When the A/C 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 A/C 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.
Cool-n-Save allows the scientific principle of energy efficiency used for years by large corporations to save money to be applied to almost any home or office A/C system.
Saving you Money
When applied to you’re A/C 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, you’re A/C unit can transfer heat much more efficiently to the outside air, greatly increasing its EER (Energy Efficiency Rating.)
This increased energy efficiency saves you money in two ways: First, the lower temperatures in the A/C compressor itself means it runs at a lower pressure, allowing it to work using less energy; Second, you’re A/C unit will run for shorter periods since it will transfer heat much more efficiently. This results in your A/C unit using much less electricity, lowering your summer cooling bills!
Incorporating the Ultimate Filter
During the product development phase, the Cool-n-Save design team addressed the possibility of scaling on air conditioner condenser fins and coils. Scaling can occur when high levels of calcium are present in the water supply, causing calcium carbonate molecules to attach to a surface. These tiny crystals will continue to grow until treated and scale will form.
To combat this problem the design team enlisted the help of some of the nation’s foremost experts in water treatment technology, including Paul Puckorius and Smart Release Technology™, to develop the water treatment filter for the Cool-n-Save system. In addition to filtering out common sediment, the polyacrylate chemical used in the Cool-n-Save water treatment filter combines with scale forming molecules and distorts their geometry, preventing them from attaching to one another. The inhibited calcium molecules are dispersed through water and washed away, preventing them from adhering to the air conditioner’s heat transfer surface.
Tulane University Study
In a recent scientific study completed by the Department of Mechanical Engineering of Tulane University, researchers demonstrated that the Cool-n-Save greatly increases the efficiency of air conditioning systems, and therefore can significantly lower electricity costs.
After rigorous experimentation, researchers at the university concluded that the Cool-n-Save reduces the temperatures of both the air around an A/C unit as well as the cooling fins of the unit across all humidity levels.
The Cool-N-Save was found to increase "heat-flux," a measure of how quickly heat is dissipated into the surrounding air, by as much as 170% over an unmodified AC unit.
The researchers in the Department of Mechanical Engineering at Tulane University concluded:
"The implication from these results is that by using a Cool-N-Save™, even in a climate that endures high humidity, the heat transfer from the refrigerant to the air is substantially increased."
"This effect implies that cooler air will able to circulate throughout a house and this will decrease the time the condenser unit runs, thus reducing electricity cost to the user."
