(Bolingbrook, Ill.), announced a price increase of 4.5 percent on industrial and commercial refrigeration products effective June 1. ■ Crockett Facilities Services Inc. (Bowie, Md.) has been awarded a contract by the National Aeronautics and Space Administration (NASA) for HVAC services, preventive maintenance services, and emergency repairs at NASA headquar-ters, in Washington, D.C. ■ Newcomb and Company (Raleigh, N.C.) received the Carrier 2011 President’s Award, which is given to companies that demonstrate excellence in customer service, and has relocated its Wilm-ington, N.C., office to a newly acquired office building on Merchant Court. t is the time of year when, in many parts of the country, cooling system problems involving coils tend to become more pronounced. Foul odors are especially problematic, but still more insidious are coil failures caused by formicary corrosion. The NEWS has interviewed members of the Copper Development Association (CDA) for their takes on how these prob-lems are being addressed. I THE OTHER F WORD Jim Michel, manager of technical ser-vices for the Copper Development Asso-ciation (CDA), informed us that formicary corrosion (aka “ant’s nest” corrosion due to its pattern seen under magnification) mainly occurs in tubes made from copper alloy 122 C1220. “It happens to be the mate-rial of choice for heat exchangers because of its good thermal conductivity,” he said. ■ See CORROSION AND ODOR page 22 Manufacturers ■ Danfoss (Baltimore) chairman of the board Jorgen M. Clausen has received and accepted a membership from former President Bill Clinton to join the Clinton Global Initiative. ■ Lennox Industries (Dallas) has earned the 2011 Energy Star ® Award for Excel-lence in Energy Efficient Product Design from the Environmental Protection Agency. ■ Rehau (Leesburg, Va.) announced its appointment to the Industry Advisory Board (IAB) of the Center for the Built Environment (CBE). A technician solders copper tubing in the HVAC unit at the military barracks at Fort Jackson in South Carolina during the spring of 2009. The resulting study showed improved IAQ and an unexpected benefit: a huge efficiency gain, plus odor control. Copper HVAC components are now EPA registered for use in protecting heating and air conditioning surfaces from bacteria, mold, and mildew. AHRI Launches Refrigerant Research n response to environmental con-cerns raised by the use of high global warming potential (GWP) refriger-ants, the Air-Conditioning, Heat-ing, and Refrigeration Institute (AHRI) is launching an industry-wide cooperative research program to identify and evalu-ate promising alternative refrigerants for Organizations ■ National Environmental Balancing Bureau’s next written exam for certified profes-sionals will be given on Sept. 17, 2011, and the deadline to turn in all exam paperwork and fees is June 1. — compiled by Cherie Preville I major product categories. These include air conditioners, heat pumps, dehumidifi-ers, chillers, water heaters, ice makers, and refrigeration equipment. The program, referred to as the Low GWP Alternative Refrigerants Evaluation Program, or low GWP AREP, is strongly desired by the industry, according to AHRI, to assess the research needs, accel-erate industry’s response to environmental challenges raised by the use of high GWP refrigerants, and avoid duplicative work. AHRI managed the original R-22 AREP in the 1990s, and will again coordinate and manage the industry-driven research ■ See EVALUATION PROGRAM page 21 NOMINATIONS NOW ACCEPTED FOR THE NEXT: Best in Class 2011 2 0 1 1 B Best est Instructor I nstruct or C Contest ont est Nomination deadline: June 3, 2011. ls.
