Dear Twin Tiers Chapter Members,

Time flies when you’re having fun! Only 3 more official chapter meetings left this year. Can you believe it? Thank you to all who made January’s meeting possible. A special thank you to; Art Studer of Postler & Jaeckle for the great informative tour of the BCC Ice Rink and to Chuck Gaylord of Meier Supply for his light and humor-ous presentation on the past challenges of refrigerants. The Spot Diner was definitely a nice “cozy” place to have a nice family style meeting. We will be meeting back in Owego at the Treadway Inn in February for a very exciting presentation on the CATA-LYST System by Transformative Wave Technologies. Danny Miller will be speaking about how we can get the most out of our old rooftop technology. Also thank you to all who donated to the Super Bowl Pool benefitting Research Promotion. This goes a long way to helping us meeting our goals. I hope to see you all there! Best regards, Andrew Nice Twin Tiers Chapter President

Nat ional Engineer Week

NATIONAL ENGINEERS WEEK

FEBRUARY 22-28, 2015 Engineers use their scientific skills and specialized knowledge and skills in creative and innovative ways to fulfill society's needs. Engineers help solve major technological challenges of our time - from designing efficient building systems to rebuilding towns devastated by natural disasters. Engineering has been called the invisible or stealth profession because everything around us and things we use every day have been engineered in some way, yet we may not see the engineers behind the scenes or know much about engineering. Founded in 1951, National Engineers Week (EWeek) is dedicated to ensuring a diverse and well-educated fu-ture engineering workforce by increasing understanding of, and interest in, engineering and technology ca-reers. EWeek is a formal coalition of more than 70 engineering, education and cultural societies, with more than 50 corporations and government agencies dedicated to raising public awareness of engineers' positive contribu-tions to quality of life. EWeek promotes recognition among parents, teachers and students of the importance of a technical education and a high level of math, science and technology literacy, and motivates youth to pursue engineering careers in order to provide a diverse and vigorous engineering workforce. ASHRAE sets standards for the heating, ventilation, air conditioning and refrigeration industry, in addition to certifying and educating people in the industry all across the country. The Twin Tiers Chapter of ASHRAE would like to acknowledge engineers across the Southern Tier of New York in honor of National Engineers Week, observed February 22-28, 2015.

Twin Tiers Chapter February Meet ing Deta i ls

February 17, 2015 February Chapter Meeting 

Research Promotion Night 

PRESENTATION: AddressingtheExcessiveEnergyUseofRTU’swithAdvancedRetro itControls Rooftop Packaged HVAC Units (RTUs) are the most common HVAC systems deployed on commercial buildings. This is due to low first cost and the fact they fulfill the basic functional needs of the heating, cooling, and ventilating well. (An overview of RTU basics will be included.) RTUs are responsible for more energy use than any other type of HVAC system. Historically, the paths to increase RTU efficiency reside with HVAC service agreements or ACCA 180 tune-up procedures or replacement with new units with improved efficiency ratings and features. RTU Retrofit is now a third option as an energy conservation measure that is gaining widespread acceptance and sup-port. Retrofitting RTUs with “advanced controls” is now a proven method of reducing HVAC energy use by 25%-50% by combining the power of a VFD with improved economization techniques and DCV. Danny will discuss the technical side of the advanced controls, the cost-effectiveness, and success stories. Although the CATALYST System is relatively new in the New York State area, Transformative Wave has been in-stalling this system mainly on the West Coast for over five years with approximately 600+ installations nationwide. The technology and components are not new, but are proven equipment with many years of operating experience

An Energy-Saving Air Conditioner Evaporative cooling plus drying with desiccants equals cool air for less cost

By Neil Savage

Keeping air cool in homes and offices this summer will be expensive–about 5 percent of the energy used in the United States each year goes to running air conditioners. But researchers at the U.S. National Renewable Ener-gy Laboratory (NREL) in Golden, CO, have come up with a new air-conditioner design that they say will dramati-cally increase efficiency and eliminate gases that contribute to global warming.

“The technology we have today is nearly a hundred years old,” says Eric Kozubal, a senior engineer at NREL. Kozubal and colleagues have come up with an air conditioner that combines evaporative cooling with a water-absorbing material to provide cool, dry air while using up to 90 percent less energy. The desiccant-enhanced evaporative, or DEVap, air conditioner is meant to addresses the old complaint, “It’s not the heat; it’s the humidi-ty,” more efficiently.

Evaporative cooling–blowing air across a wet surface to promote evaporation–has long been used in so-called swamp coolers. A method called indirect evaporative cooling improves on this design, dividing air into two streams, which separated by a polymer membrane. Water is passed through one airstream, making it cooler and wetter; the cool air cools the membrane, which in turn cools the air on the other side without adding water.

But air can only hold so much water vapor, so in humid climates the effect is limited. On a 32 ºC day in Houston, Kozubal says, evaporative cooling may only bring the temperature down to about 27 ºC. Ideally, to provide a comfortable building, an air conditioner should cool air to 13 or 16 ºC.

NREL overcomes the humidity problem by adding another step, the use of a material known as a desiccant that absorbs moisture. NREL uses a liquid desiccant, a syrupy solution of lithium chloride or calcium chloride, about 44 percent salt by volume. In this setup, another membrane separates the desiccant from air traveling through a channel. The polymer membrane has pores about 1 micrometer to 3 micrometers in diameter, big enough that water vapor passes through easily while the salty liquid stays put. The membrane is also coated with a Teflon-like substance to repel liquid water. The desiccant pulls moisture from the airstream, leaving dry, warm air. Then it’s back to indirect evaporative cooling: in a second channel, water evaporates to cool a secondary airstream, which in turn cools the first airstream, and out comes cool, dry air.

“I think it’s very promising,” says Anthony Jacobi, codirector of the Air Conditioning and Refrigeration Center at the University of Illinois at Urbana-Champaign. “I don’t believe the idea of integrating these technologies is very new. Do-ing it successfully may be.”

An Energy-Saving Air Conditioner (Cont.)

What’s new, Kozubal says, is a design that manages to merge evaporative cooling and desiccant drying into a cost-effective system. “It makes this type of air conditioning viable for commercial and residential processes for cooling,” he says.

The industry is working on a variety of methods to improve the efficiency of air conditioning, Jacobi says, from the use of heat exchangers to improvements in the compression systems of traditional machines. “It’s an area of great importance to the nation, because about a third of our nation’s energy use is in buildings.”

The U.S. uses about 100 quadrillion British Thermal Units each year, according to the U.S. Energy Information Administration. Up to 40 percent of that is used in buildings, with about 5 percent going to air conditioning. Kozu-bal says his system could cut that in half in less-humid areas and by up to 90 percent where humidity is high. “When you talk about a technology that can save 2 to 3 percent of the nation’s entire energy supply, that’s quite a lot,” he says.

The desiccant used in the system is relatively harmless (calcium chloride is used in road salt), though its corro-siveness requires that metal be eliminated from the hardware. What’s particularly attractive is that it replaces the chlorofluorocarbons that are used as the refrigerant in traditional air conditioners. Those CFCs can easily leak, and every kilogram of them provides the same greenhouse gas effect as about 2,000 kilograms of carbon diox-ide.

Kozubal says it might take about five years to develop the system to a point where NREL can hand it off to in-dustry for commercialization. The system is designed to replace existing systems without many changes, so it could be phased in as people upgrade their old air conditioners.

The desiccant can be reused simply by heating it up to boil off the water it’s absorbed. In an industrial setting, that might be done using waste heat from another industrial process. In the home, natural gas or solar energy would work. In fact, Kozubal says, the setup could make solar thermal energy systems, which absorb sunlight to heat a home and its water, more cost effective. During hot summer days, solar energy that might otherwise go to waste could therefore actually help keep a building cool.
