ASHRAE Research: Laboratory Test of Five Non-Chemical Devices Used in Cooling Towers Showed No Effectiveness in Preventing Biological Growth

April 7, 2010 - ATLANTA ?New research supported by ASHRAE indicates that non-chemical devices (NCD) marketed to control the growth of biological agents, such as Legionella in cooling towers, may not materially reduce biological growth.

Research project No. 1361, Biological Control in Cooling Towers Using Non-Chemical Water Treatment Devices, a two-year project recently completed by Dr. Radisav Vidic at the University of Pittsburgh, evaluated five non-chemical devices using different technologies to control biological activity in a model cooling-tower system. The devices studied included a hydrodynamic cavitation device, pulsed and static electric field devices, an ultra-sonic device and a magnetic device.

In Dr. Vidic?s research, none of the non-chemical devices measurably reduced planktonic or sessile microbial populations in comparison to no-treatment tests and to a conventional chemical microbial control treatment protocol. The findings appear to be inconsistent with previous research by non-chemical device manufacturers and some independent researchers on some of the same devices tested in the ASHRAE study. Those other studies reported measurable degrees of biological control within the parameters of testing conducted.

?These results suggest that equipment operators, building owners and engineers should consider taking more frequent water sample tests for their systems that rely on NCDs for biological control. If the testing shows an issue, one possible measure is to add chemical treatment capability to their system to prevent a potential health hazard from developing until additional research and field testing can resolve this question,? according to Dr. Vidic .

The study results are still subject to final approval by the sponsoring technical committee, TC 3.6 ? Water Treatment. ASHRAE anticipates formal approval and the release of the final report for this project at its 2010 Annual Meeting Conference in June.

Lennox Introduces New Home Energy System That Uses Solar Power

LAS VEGAS, NV (Jan. 19, 2010) ?Lennox unveils NEW Home Energy System that uses solar power as an energy source for central heating and cooling and beyond. State-of-the-Art SunSource? Home Energy System provides simplest way for homeowners to bring solar power into the home and save on utility bills.

Lennox Industries, a leading provider of customized home heating, cooling and indoor air quality products, today introduced the patent pending SunSource? Home Energy System a new solar-powered central heating and cooling system that reduces overall household electricity consumption without the costs associated with traditional solar installations at the International Builder's Show in Las Vegas.

The new SunSource Home Energy System not only harnesses solar energy from the sun to reduce the electricity consumed by a residential heat pump or air conditioner, but also is able to use that solar power to operate other devices in the home that consume electricity, such as lighting and appliances, when the heating and cooling system is not running. In addition, if the SunSource system generates more power than is used by the home, that power will be sent back to the utility company, which may entitle the homeowner to a credit on their utility bill.

According to the U.S. Department of Energy, the typical U.S. household pays $2,200 a year on utility bills, and the bulk of those energy costs?between 50 and 60 percent?comes from heating and cooling the home.

"With the new SunSource Home Energy System, homeowners can reduce the energy consumption associated with heating and air conditioning, while also significantly cutting their overall utility bills," said John Hurst, vice president, product management at Lennox International. "Lennox is the first heating and air conditioning manufacturer to harness solar energy for central heating and cooling and beyond, and the new SunSource system is really a gateway to the future of innovation in the HVAC industry."

The SunSource Home Energy System is composed of:
# A solar-ready, high efficiency Lennox air conditioner or heat pump that has been specially enhanced to serve as the platform for this new home energy system.
# A Lennox solar subpanel that provides the connection between utility- interactive solar power system and the HVAC unit.
# One to 15 roof-mounted solar modules that harness clean, sustainable energy from the sun and use it to run the home's central heating and cooling system as well as other appliances?the more modules, the more homeowners can reduce their utility costs.
# A communications system that allows homeowners to monitor each solar module's operation and energy production online, as well as other environmental benefits such as the amount of carbon offset.


"The most efficient air conditioners and heat pumps manufactured by Lennox will automatically come 'solar ready,' just like many of today's television sets are automatically sold as 'HD ready,'" said Hurst. "Consumers who purchase these systems will have the option to integrate a solar package at installation or at a later date. And because the system is expandable, homeowners can start small with a couple of solar modules and add more in the future, for a total of up to 15 solar modules per outdoor unit and added energy savings."

Energy Savings and Tax Credits Equal Real Cost Savings for Homeowners
As an example, a consumer who lives in a typical 2,000-square-foot home in Corpus Christi, Texas, can reduce the electricity usage associated with heating and cooling his or her home by approximately 12 percent annually by installing a Lennox high-efficiency air conditioner* with two solar modules and by 86 percent by installing the air conditioner with 15 modules. In Tulsa, Oklahoma, the homeowner would see around a 25 percent reduction in air conditioner electricity usage with two solar modules, and about a 180 percent reduction (meaning more energy production than air conditioner consumption) with 15 modules. The savings increase even more in sunnier areas of the country.

In addition to the costs savings and incentives offered by many local utility companies for using high-efficiency heating and cooling equipment and/or renewable energy sources, the new SunSource system makes homeowners eligible for federal and some state solar tax credits. In fact, these benefits, when combined, can cover up to 94 percent of the cost of the solar modules, including installation**.

The new Lennox SunSource Home Energy System will be available with several products from the Dave Lennox Signature® Collection, which is the company's line of premium heating and cooling products, offering the quietest, most efficient operation and a premier level of performance. The Lennox SunSource Home Energy System may be paired with Dave Lennox Signature Collection air conditioners and heat pumps beginning in May 2010.

For more information or to obtain a price quote for customized installation of the SunSource system, homeowners can contact their local Lennox dealer or call 1-800-9-LENNOX.
