Appliance Design - September 2008 - (Page 18) NEwS watch Haier products have been installed in all Olympic venues in Beijing and the cohost cities. Products such as refrigerators, air-conditioners, washing machines and water heaters were used. Haier supplied 13,236 refrigerators, all CFC-free, with 5,353 using carbon dioxide as a natural refrigerant. Fifteen hundred green washing machines were installed in 18 laundries, including 530 detergent-free washing machines and more than 700 doubledriven washing machines. Haier installed 2,864 sq. meters of solar power panels for air-conditioners and water heaters in the Qingdao Olympic Sailing Center, the Beijing Olympic Green Tennis Court, and the Olympic Village Restaurant. a third of the power of a comparably sized LCD TV, allowing it to be operated off a Sharp triple-junction, thinfilm, solar-cell module whose surface area is roughly the same size as the TV screen. The company will market the TV and solar module as a pair. ity improve heat transfer rates for the system. Preliminary results of the NIST research also indicate that, in sufficient concentrations, nanomaterials enhance heat transfer by encouraging more vigorous boiling of the mixture. The tiny particles stimulate, in effect, double bubbles—secondary bubbles that form atop bubbles initiated at the boiling site. Bubbles carry heat away from the surface, and the fact that they are being formed more efficiently because of the nanoparticles means the heat gets transferred more readily. NaNO aIDS hEat tRaNSFER.

At the Hokkaido Toyako Summit in July, Sharp Corp., Tokyo, exhibited a prototype solar-powered television, intended to serve the millions of people around the world without access to utility-supplied electricity. The 26-in. LCD TV consumes only researchers have found that adding nanoparticles to standard mixes of lubricants and refrigerants can yield improved energy efficiency of large commercial and institutional cooling systems. NIST experiments found that dispersing “sufficient” amounts of copper oxide particles (30 nanometers in diameter) in a common polyester lubricant and combining it with an R134a refrigerant improves heat transfer by between 50 percent and 275 percent. The researchers say that improvements in heat-transfer performance occur because nanoparticles of materials with high thermal conductiv- QUALITY TO PROTECT PEOPLE LCDIs • GFCIs • ALCIs TOWER– LCDI GFCI ALCI • Customized to meet your specs • Priced from our own Asian plant to keep you competitive • Customer service from our USA headquarters for quick satisfaction 25 Reservoir Avenue, Providence, RI 02907 • Tel: 401-467-7550 • Fax: 401-461-2710 TOWERManufacturing Corporation www.towermfg.com September 2008 REaDY FOR REach? The results of a survey by IPC, an association of connecting electronics industries, found that the electronics industry is not prepared to comply with the European Union’s Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. The survey found that more than 40 percent of manufacturing and purchasing personnel have no understanding of the standard. The same holds true for nearly one-third of senior management, 29 percent of engineering personnel, and 28 percent of environment, health and safety personnel have no understanding of REACH’s impact. In contrast to RoHS, which covers a narrow scope of substances in electronic products encompassing about 100 different chemicals, REACH covers substances in nearly all applications, totaling about 30,000 unique chemicals. While RoHS can address entire classes of substances at a time, REACH addresses them each individually. Where RoHS requires supplier-to-customer communications, the REACH regulation makes bidirectional communication throughout the supply chain imperative. The electronic survey, sent to executives throughout the electronic interconnect supply chain in North America and Europe, reveals that only 18.3 percent of companies have identified and/or inventoried all substances in their products. In addition only 60.5 percent of chemical supplier respondents are planning to register or pre-register substances at all. < 18 applianceDESIGN AD09074Tow1.indd 1 www.applianceDESIGN.com 8/2/07 10:26:53 AM http://www.towermfg.com http://www.appliancedesign.com
