Eco friendly products are definitely a big help to the environment. Turning on your air conditioning equipment through the summer is now a part of our daily reflexes, along with opening the doors and flipping on the lights. When payments come, though, it is also a chronic, often compulsive reflex to spend hundreds of dollars to electrical power utilities – you could not reside in our own perspiration, in the end, when the temperature outdoors is 100 degrees, could you?
DOE’s National Renewable Energy Laboratory (NREL) has combined 3 classic methods of cooling down the air into a single creation that could conserve 50 to 90 percent of one’s monthly electricity bill (on air-con). The creation is known as “DEVap” (Desiccant-Enhanced eVaporative air conditioning). Eric Kozubal, one of the brains, said “The idea is to revolutionize cooling, while getting rid of an incredible number of metric tons of carbon from the atmosphere.”
Kozubal additionally asserted that their own DEVap device makes use of three methods to remove warmth from the air: filters, evaporative coolers as well as dessicants. Each of these had been used separately since ages, but nobody thought merging them in such a fashion could save power in these quantities.
DEVap makes use of water along with liquid dessicant (such as those silica gel balls present in new shoes, merely liquid) to draw in the outside air, exhaust a few of it and return cool, dry air to the area being cooled. These two techniques improve the dehumidification part, which is the most energy-consuming. An example of a basic evaporative cooler would be a water-drenched bed sheet put in your window, or having a fan blow air on it. The actual evaporation of water could cause the sheet to lose temperature and cool the air which hits it. The same comes about when you shiver if you go out from the sea, even though it is hot outdoors.
Still, only the application of dessicants and evaporative coolers isn’t sufficient in places with excessive air moisture. For these places, membranes start working. The membranes in the DEVap are hydrophobic, which means water tends to bead up instead of saturate through the membranes, just like it comes about when water is falling on a freshly waxed car. This allows the filters to control the fluid flows inside the cooling center. “It’s that property which keeps the water as well as the desiccant separated from the actual air stream,” Kozubal said.
Each one of these 3 methods cool the oxygen and dehumidify it in one stage, without needing refrigerants. Classic A/C machines may use CFC of HCFC as the warmth exchanging liquid, which is the majority of the times environmentally insensitive, because the pipes that contains them eventually stop working and release these potent greenhouse gases to the environment. A pound of CFC or HCFC inside refrigerant-based A/Cs contributes as much to global warming as 2,000 lbs of carbon dioxide. The DEVap replaces the refrigeration cycle from classic A/Cs with an absorption cycle that is thermally activated and that uses much less power.
NREL wants to license the technology to numerous industry companies, so in a few years it should be able to transform things radically in just how much power we utilize for cooling our own houses and offices.
