The Council of American Mechanical/Electrical Engineers, a coalition of members within the American Council of Engineering Companies, is planning several events in conjunction with the ASHRAE Summer Meeting in June in Salt Lake City.
The Tempstar product line from International Comfort Products includes 25-ton PGE300 package gas/electrics with up to 9.5 EER efficiency. This two-stage rooftop unit uses R-22 refrigerant with multiple hermetic-type scroll compressors. The ASHRAE 90.1-compliant unit features independent cooling circuits to provide part-load cooling operation.
The term smart materials refers to an interesting class of materials that are able to respond dynamically to external stimuli like heat, humidity, ultraviolet light and pressure. Smart materials systems have sensing and actuating functions that are used for an increasing number of engineering and commercial applications. Currently, the application of smart materials spans most industrial sectors including electronics, medical diagnostics, treatment and surgery, automotive and industrial research processes that require control and sensing. According to a soon-to-be-released and updated technical market research report, RGB -154N Smart Materials: A Technology and Market Assessment from business communications co., inc. (www.bccresearch.com) , the worldwide smart materials market is estimated at $8.1 billion in 2005 and is expected to rise at an average annual growth rate (AAGR) of 8.6% to $12.3 billion in 2010.
