While off-peak prices may be lower, prices during peak cooling hours will be dramatically
4、 higher. This pricing scheme favors chiller plants capable of operating with multiple energy sources. By choosing the right mix of chillers, youll realize substantial savings by balancing your operation to use the most economical energy source available at any given time. Only YORK gives you a full
5、range of chiller choices to deliver real-world energy performance at real-time energy pricing. You can go with Millennium electric chillers to take advantage of hours of low-cost electricity. When electric power is expensive, even high-efficiency, electric chillers cant compete with Millennium gas-f
6、ired absorption and gas-engine-drive chillers that exploit low summer gas prices. You can also select Millennium steam-absorption or steam-turbine-drive chillers that tap economical steam sources. These proven technologies - along with intelligent controls that optimize chiller operations based on v
7、ariable energy costs - are already achieving unprecedented energy savings in multiple- chiller plants. Call YORK today.

17、N 40-1 ARI-ENGL 1998 0757b50 0532502 b25 Fred Turner Editor The Show Goes On o location is going to please everyone, but the West Coast locale of this years International Air-conditioning, Heating, Refrigerating Exposition is a great opportunity for visitors from the Pacific Rim countries. Many of t
18、he 14,364 regis- tered visitors who attended 1986 AHR Expo in San Francisco came from either Japan, Korea, Singapore, Malaysia, China, Taiwan or Vietnam. The show manag- ers expect a strong international attendance again this year. In all, about 18,000 visitors and 18,000-plus registered exhibitors
19、are expected. A sellout for the third straight year, the show is limited by the size of the Moscone Center to 1,0 14 exhibitors and 297,816 ft2 (27 667 m2) of exhibit space. This issue includes our annual show guide and contains hundreds of pages about the show. Features include a floor plan of the
20、exhibits, an alphabetical listing of exhibitors, messages from sponsors, a map of San Francisco and pages of products that will displayed. A LESS visible part of the AHR Expo is its role in funding much of ASHRAEs research. In the 1996-97 fiscal year, for example, ASHRAE spent $2.3 million for resea
21、rch. Contributions by individuals and organizations provided $1.6 million. The Expo provided $1.8 million. The Expo money is funding about 90 active research projects which are handled by contract with universities and research firms. The projects are overseen by the 13-member ASHRAE Research Admini
22、stration Committee (RAC) and 90-plus technical committees and task groups. Ultimately, the research becomes the foun- dation for ASHRAE Handbook chapters, special publications, standards and tech- nical papers. Some examples of on-going projects include 875-RP (research project) on advanced methods
23、of calculating peak cooling loads; 890-RP on updating the tables and design weather conditions in ASHRAE Handbook; and 891-RP on validating Standard 129, Standard Method of Measuring Air Change Effectiveness. The use of Expo funds for research originated with the first Expo in 1930. The practice has

It changed its name in 1976 to The Char- tere
33、d Institution of Building Services Engineers (CIBSE), and this October celebrated its Centenary with a conference and ex- hibition in which ASHRAE played an active role. The Year 1897 was not just important for the British heat- ing and ventilating business, but for the modern world. In this year, t
34、he first cathode-ray tube was developed, although it was not until 1907 that this was linked to “electric vision.” In the same year, the Hawaiian Islands became part of the U.S. and a gold rush in the Klondike fields yielded $22 million in gold in just 12 months. It was also in 1897 that Mark Twain
35、cabled the New York Times from Europe that “The reports of my death are greatly exaggerated.” More than 500 delegates attended the CIBSE Centenary meeting at Alexandra Palace, London, the venue in 1936 of the worlds first high-definition TV broadcast. More than 70 papers were presented over three da
36、ys. Cele- brating the Institutions Centenary in an original way, a virtual conference was run in parallel with CBSEs National Confer- ence. The “virtual conference” is believed to be a first for the See British Institution, Page 7 7 LONDON-To commemorate the CIBSE Centenary, ASH- RAE President Donal
37、d Holte presented a gavel crafted from an American live oak to CIBSE President Geoffrey Brun- drett. In his remarks, Holte noted that oak is the national free of England and the state tree of Georgia, home of ASHRAE Headquarters. The life of an oak spans 300 years,“ said Holte. The first 700 years a
38、re a period of growth, the second a period of maturity, and the last 700 its years of decline. We are here to celebrate the 7 O0 years of maturity which follow for CIBSE.

Arnold spoke about “Air Conditioning and the Evolution of Modern Office Building Design.” His presen- tation was illustrated with excellent photographs

Topics of other notable papers included displacement ven- tilation applications, gas-fired absorption cycle technology for buildings, lighting control and man- agement, the conflict between holistic building design and facility manage- ment and the new Parliamentary building in Westminster.

47、tock, ASHRAEs director of publishing services. ASHRAE President Don Holte was introduced at the break- fast meeting by Tim Dwyer, chair of the CIBSEIASHRAE Group. Holtes well-received speech emphasized the need for engineers to use more “brain than brawn” in the systems that maintain indoor environm
48、ents. “We have a responsibility to protect the environment and to ensure an adequate supply of energy for future generations.” Holte reiterated the need for ASHRAE to press forward with its standards for indoor air quality, energy conservation and indoor comfort, all of which impact directly or indi
49、rectly the global outdoor environment. Following Holtes presentation, an update was provided on a research project jointly sponsored by ASHRAE and CIBSE.
