May 12, 2009 – Energy fair is conduit for information
Renewable energy is no longer relegated to pie-in-the-sky discussions between green living advocates. Saturday’s Mesquite Energy Fair demonstrated how renewable resources have gone mainstream.
The proof: more than 15 vendors and 275 visitors connected for six and a half hours at the first-ever Mesquite Energy Fair at CasaBlanca Resort.
The event, assembled by the Mesquite Task Force’s energy fair subcommittee, in conjunction with the city’s 25th anniversary celebration, enabled consumers to engage in one-on-one discussions with renewable energy system providers and installers and businesses offering energy efficiency/conservation products.
Michele Burkett, energy fair subcommittee chair who headed coordination of the energy fair, said the number of vendors and fair-goers exceeded her expectations.
Said Burkett, “The comments were: ‘This is great,’ ‘we learned a lot and we’d like to learn more;’ ‘it’s fantastic. We want it back next year.’ This is what we wanted for the community.”
Parked in front of the CasaBlanca casino was a trailer featuring a Coolerado air conditioner powered by a solar photovoltaic system.
“We’ve been trying to keep up with everyone all day,” said Charlie Goessman, owner of Tri-Force Mechanical Contractors, who manned the Coolerado exhibit.
The exhibit served as an introduction to the energy fair, which featured a gamut of renewable energy products. There were solar thermal water heaters, solar panel installation information, lighting, geo-exchange unit demonstrations, energy-conserving products from solar window screens to window tinting, an Overton Power District display and water-efficient landscape information.
Geo-thermal experts said geo-exchange systems “are, according to the Environmental Protection Agency, the most energy-efficient, environmentally-clean and cost-effective space conditioning systems available.” Power bills are reduced by 70 percent during the life of the system, they said.
DVT columnist Stewart Somerville, owner of Alternative Power Systems in Cedar City, gave a nuts-and-bolts lecture about on-the-grid and off-the-grid solar photovoltaic systems combined with energy efficiency measures homeowners can take to reduce power bills and stabilize energy costs.
Mike Stergois of Best Building and Lumber people could do all their green-product shopping in Mesquite.
“Over 75 percent of our staff is trained in green products,” he said. “We have over 1,500 products in stock — building materials, plumbing, home décor and electrical.”
Stergois said switching to a greener lifestyle begins with making a home more energy efficient through installation of weather stripping, energy-conserving windows, insulation, lighting and energy-efficient appliances.
“Before you invest in the bigger renewable systems, make your home more energy efficient first to get the full value of those systems,” Stergois said.
Mayor Susan Holecheck said energy will be the most important issue within the next decade, adding that the community-created Mesquite Energy Fair was a reflection of “America’s can-do spirit.
“Now is the time to not only break our long-standing dependence on fossil fuels, but to go with the green industry with the creating of millions of jobs,” Holecheck said. “Energy will be the most important problem within the next decade. That’s why you’re all here today. The nation needs to develop safe, clean, secure and sustainable energy.”
Lydia Ball, energy outreach representative from Senator Harry Reid office, told the audience that the energy fair “was a perfect example of education to the people. These resources are here now.”
Linda Faas, member of Defend Our Desert, said: “I think people are very engaged in what’s happening here; they’re trying to get answers.”
Arlis Swartzendruber, vice-chair of the city’s Energy Task Force, said the fair was a good first step for community outreach, but wanted the task force to continue its mission to push for alternative energy options in homes and eventually attract green energy industry to Mesquite.
“I’d like to see developers that do small developments provide an option for solar-powered homes,” he said. “This has unlimited potential.”
“We’ve had people telling us that they want us to do it again,” said Jim Norris, energy fair subcommittee member. “They want more vendors next year and said the fair was really worthwhile. People are pumped.”
Vendors, too, reported that the fair had been worthwhile for them. They said people came to the fair armed with good questions, and several vendors said the fair brought them new customers.
“This is what the people want,” said Bob Davidow, Energy Task Force member. “They came for answers.”

May 5, 2009 – Business and Finance by Bob Challinor
Charlie Goessman is bringing what may be one of the most exciting show-and-tell exhibits at the Mesquite Energy Fair, on May 9.
Goessman, who works for TriForce Mechanical Contractors in Mesquite, is bringing a trailer outfitted with a solar photovoltaic system and an energy-efficient “Coolerado” air conditioning unit.
The coupling will demonstrate the reality of solar-powered air conditioning. The solar photovoltaic system will contain four panels, enough to power the Coolerado C60, a six-ton air conditioning unit capable of efficiently cooling 3,000 square feet and 20 people.
“We’ll have the trailer here Friday and get training for it and then have it available for people to see at the energy fair,” Goessman said.
The energy fair will be held 8:30 a.m. to 3 p.m. in the CasaBlanca Showroom.
The Coolerado air conditioning system is 10 times more efficient than traditional air conditioning units, according to information presented on the Coolerado website at www.coolerado.com. The Coolerado C60 unit uses 600 watts of power (the equivalent of six 100-watt light bulbs) to cool the same space as traditional air conditioning systems using 6,000 watts of power.
Coolerado systems use an indirect evaporative cooling process utilizing a new thermodynamic cycle called the Maisotsenko Cycle – or M-Cycle. Outside air is drawn into the air conditioner by a fan. The air is cleaned by an array of two-inch-thick filters before entering Coolerado’s patented heat and mass exchange. About 40 percent of the air entering the heat and mass exchange becomes saturated with water and is rejected outdoors. That air carries heat energy removed from the conditioned air. The other half of the air entering the heat and mass exchange is cooled without the addition of humidity and is ducted into a home or business.
Compare that to evaporative, or swamp, coolers that blast unfiltered, wet air into a building, said Rick Gillan, vice-president of Coolerado. It’s high-volume, high-humidity with dust and mold.
Gillan said Coolerado units use water to cool the air instead of chemical refrigerants. Dust and allergens are filtered at the beginning of the process, and the air is cooled incrementally through the 13-stage M-Cycle.
A Coolerado unit demonstration showed 150-degree air from a heater drawn into the air conditioning system. Conditioned air was nearly 100 degrees cooler.
“The air temperature on a roof out here is 150 degrees.” Goessman said. “The Coolerado system takes in that 150-degree air and the air comes out at 54 degrees.”
At the heart of the system is the heat and mass exchanger that economically takes advantage of the M-Cycle. The exchanger consists of several plates of a special plastic that is designed to wick water evenly on one side and transfer heat through the other side. Plates are attacked on each other, separated by channel guides.
The channel guides provide structure to the heat and mass exchanger and direct air movement within the exchanger. The guides divide the incoming air stream into “product air” (conditioned air) and working air. The product air is always separate from the working air and stays within dry channels through the entire length of the exchanger. The product air is cooled sensibly – cooled without humidity – rejecting its heat and heat energy into the working air in the wet channels through evaporation. Hot air is exhausted out the sides of the heat and mass exchanger and into the atmosphere.
The process is repeated multiple times in a short physical space within the exchanger, resulting in progressively colder “product” and “working” air temperatures.
The indirect evaporative cooling method works like a car radiator, transferring heat outside without hot liquid escaping or hot air getting in.
Customers who have purchased Coolerado air conditioners report that the air coming into their homes is “more comfortable.” Coolerado won the second annual Excellence in Renewable Energy Award from Governor Bill Ritter.

April, 2009 – Catching up with energy-efficient cooling systems: Coolerado
Cooling season is fast approaching—in some parts of Western’s territory, it’s already here—so it is a good time to revisit two promising, energy-efficient, cooling technologies that could help utilities control this rapidly growing summer load. This month, Energy Services Bulletin looks at the Coolerado, which last appeared in the June 2005 issue.
Since its introduction five years ago, the Coolorado has evolved, gained wider acceptance and earned recognition. In late January, the Colorado Governor’s Energy Office presented the Denver-based Coolerado Corp. with the Governor’s Excellence in Renewable Energy Award. The award recognized Coolerado for developing a solar-powered mobile air conditioner, “The closest thing to free air conditioning,” as Coolerado Executive Vice President Rick Gillan described it.
Not typical evaporative cooler
Although the company refers to its equipment as an air conditioner, the system represents very different technologies. Utilities should take that into account when considering equipment for a rebate program, or recommending a particular technology to a customer.
The Coolerado, a type of indirect evaporative cooling system, can take the place of conventional air conditioners in most applications, especially in dry and semi-humid climates. Direct “swamp” coolers add moisture to cool an air stream, making it unsuitable for humid climates. In the indirect process, the air does not come in contact with water, but the temperature of the delivered air is typically warmer than a swamp cooler.
The Federal Energy Management Program described Coolerado as an ultra-cooler because its indirect evaporative process cools to significantly lower temperatures than a swamp cooler can, without adding humidity. A heat and mass exchanger (HMX) cools the air instead of water, as in a swamp cooler, or refrigerant and compressors, as in an air conditioner. The result is air-conditioner temperatures for about 15 percent of the electricity an air conditioner would use….(read more)

Friday, February 13, 2009 – Coolerado seeks hot sales for solar-powered AC unit
A Denver-based company that makes high-tech air conditioners isn’t letting the recession get in the way of success. And the effects of global warming don’t hurt either. Coolerado Corp. plans to boost sales from between 100 and 150 units in 2008 to 5,000 units, with a corresponding rise in profitability.
“It’s a steep climb, but that’s our objective,” CEO Mike Luby said.
Coolerado units use water to chill fresh, outside air, without adding moisture to a building, and consume just 15 percent of the energy used by traditional air conditioners, according to company executives.
While Coolerado’s unit uses water to chill air, it’s not a swamp cooler because the water never comes in contact with the air, and moisture from the water never enters the building. Link to Article

January 29, 2009 – Coolerado Receives Renewable Energy Award
DENVER – Coolerado Corporation, manufacturers of high efficiency air conditioners, today announced the company received the prestigious “Governor’s Excellence in Renewable Energy Award” from Colorado Governor Bill Ritter this week for the outstanding contributions made by a small business to protect the environment and support clean power through renewable energy.
“It may seem strange that a company with a product that consumes energy received a renewable energy award, but Coolerado air conditioning systems use one-tenth of the energy required by the most efficient conventional systems,” said Mike Luby, CEO of Coolerado. “Our air conditioners achieve a tenfold reduction in greenhouse gases, because of reduced power generation needs, and they are green, using no chemical refrigerants.” Link to Article

June 24, 2005 – Coolerado Colorado has a hot A/C idea
Billed as the most efficient air conditioner ever made, the Coolerado Cooler may be one of the hottest inventions ever to come out of Colorado — and has left the A/C industry frozen in astonishment.
The revolutionary new air conditioner uses water to fuel the cooling process — but that’s where its similarity to an evaporative cooler ends. It requires no chemical refrigerants and, according to testing done by the U.S. Department of Energy, consumes about one-fourth the electricity of a traditional air conditioner.
R&D magazine’s 100 Awards program picked the Coolerado Cooler as one of the most technologically significant products introduced to the world in 2004. Link to Article

June, 2005 – New Cooler Combines Comfort, Efficiency
A revolutionary new cooling technology that delivers the comfort of an air conditioner with the efficiency of an evaporative cooler is creating a big buzz among utilities and energy and facility managers.
Coolerado, located in Arvada, Colo., puts a 21st century spin on evaporative cooling. R&D Magazine’s 100 Awards program hailed the system as one of the year’s most technologically significant products introduced to the world in 2004. Sacramento Municipal Utility District and the Colorado Governor’s Office of Energy Management and Conservation have partnered with the company on demonstrations.
“It cools as well as an air conditioner, and on a third the amount of electricity,” said OEMC Senior Deputy Director Ed Lewis. “It doesn’t have a compressor, there are no greenhouse gas effects and unlike a swamp cooler, it doesn’t release water into the air that enters the building.” Link to Article

April, 2005 – Refrigeration & Air Conditioning: Converting Disbelievers
Thermodynamic cycle proves the impossible is here and ready to use.
Physics and thermodynamic students are taught that it is theoretically impossible to cool below the wet bulb temperature of air by evaporating water. It’s no surprise, then, that thousands find it hard to believe that a company in Arvada, Colo. has created a thermodynamic cycle that not only can cool to that level, but is also being licensed for use in appliances.
The technology, developed by Idalex Technologies, is called the Maisotsenko Cycle (M-Cycle), named for its discoverer, Dr. Valeriy Maisotsenko.
“The M-Cycle is a more efficient way to transfer heat that uses the properties of evaporation in unique three-dimensional flow patterns,” says Rick Gillan, president of Idalex. “The working fluid stream is fractioned off in increments and cools the remaining working fluid and the product fluid. This process occurs multiple times until all the working fluid is saturated and used. After passing through the cycle to cool air, up to six times more heat is removed than conventional air-cooling processes.” Link to Article

September, 2004 – Water Blows Hot Air
Coolerado Air Conditioner is announced the R&D 100 Award Winner!
The sweltering heat of dry regions is not only uncomfortable but can lead to illnesses. To improve living conditions, cooling solutions – which require chemical refrigerants, like Freon, or expensive, polluting, and energy-consuming compressors – are used. A new cooling process has now emerged, however, which uses a small amount of the most abundant fuel known to man – water. The process is embodied in the Coolerado Cooler, an air conditioner that delivers cold, dry air without a compressor or chemical refrigerants and uses 82% less power than a standard vapor compression system.
Developed by a group of researchers at Idalex Technologies, Arvada, Colo., this product rejects heat from one location where it is not wanted and transfers it to another, just like refrigeration. It uses the Maisotsenko thermodynamic cycle, which capitalizes on the psychrometric energy found in our atmosphere. The cycle captures this energy by exploiting the latent heat of evaporation without adding humidity to the building being cooled.
Except for a fan to move the air across the Coolerado heat exchanger and into the building, the cooler consumes no electricity. After fresh air enters the cooler from the supply side, heat is removed by evaporating water from one side of a plate heat exchanger, pulling the heat away from the air on the other side. The rejected heat is then carried into the atmosphere outside the building. PDF format
