4、I N G YOU THINKABOUT BUILDING CONTROL SYSTEMS IS GOING TO C HANG E. I Everything you ever thought about building control systems is about to change. And it? all because of the new Intelligent Automation System from Siebe Environmental Controls. While other companies were talking about incorporating

5、BACnetTM and Lon Works protocols into their products, Siebe did it. With new controllers, sensors, valves, and actMators - a new system designed to deliver scalable, open solutions with real options and real benejts.

Visitors with flexi- ble schedules are encouraged to attend the show on Tuesday afternoon and Wednesday because hotel room av

ASHRAE, which co-sponsors the show with the Air-conditioning and Re- frigeration Institute (ARI), will be hold- ing most of its technical programs in the show facility. This approach was first used in Atlanta in 1996, and was popular because it placed engineers

18、 close to the show while they attended symposia, seminars, forums, and technical and poster sessions. One of the highlights of the ASHRAE technical program is the annual free public session. This years session is ti- tled “What You Need to Know About the Deregulation of Electric Power.” Many of the

The building on the Uni- versity of Pennsylvania campus also is a 458-car parking garage and a J5,SOO ftz (

Tour Includes Multiple Use Chiller and Ice Storage Plant ATLANTA-ASHRAE members attend- ing the 1997 Winter Meeting will have an opportunity to tour one of the largest and most unique chilled water and ice storage facilities in the Eastern U.S. The plant is known as MOD-6 (M

28、od- ule 6) because its the sixth in a series of six plants that provide chilled water to the University of Pennsylvania campus through a six-mile underground loop. The plant is noteworthy because of its fully automated 13,400 tons (46 900 kW) and of chillers 20,500-ton-hour (260 GJ) thermal storage

29、plant, and be- cause it is combined with a 658-car parking garage and 15,500 fi2 (1 440 m2) ofretail storage space. The plant was built for $25.2 million in SOO days and provides climate control for administrative, academic and re- search space. The system is designed to save between $500,000 and $7

30、00,000 annually, according to James Wargo, the Universitys executive director for physical plant. MOD-6 uses three large compressors to chill glycol to 22F (-6.6C) during the evening hours when electricity costs are lower. The glycol is then pumped through 20 ten-foot (3 m) serpentine coils which ar

31、e submerged in water. Ice accumulates around the coils. During the day, the process reverses: the melt- ing ice chills the glycol. Through plate- and-frame heat exchangers, the glycol then chills water for the Universitys chilled water loop. The process of combining three func- tions created challen

32、ges for the engineers, the architects, the project managers, and the general contractor. One challenge was the aesthetic im- pact on the campus from combining a large parking garage with a chiller plant, standing four stories high with deeply planted chiller tanks. “People feared it would be too gig

33、an- tic,” said John Bower, the MOD-6 archi- tect. Bower designed the structure in modules, exaggerating smaller elements and playing them against larger surfac- es. “The stairs, elevators, cooling tower, and piping were all opportunities for ar- chitectural expression,” he said. The result is a buil

34、ding that blends with other campus buildings and a near- by church, and has won architectural de- sign awards.

US. companies exported in 1995 more than $4.4 bill

36、ion worth of air- conditioning and refrigeration equip- ment and components. During the same period, the U.S. imported about $2 bil- lion in similar products. Much of the import/export involves U.S. and Canada and nine Canadian companies will be occupying a special Canadian Pavilion. Two other speci

37、al areas-the Building Automation and Control (BAC) Show- case and the Software Center-will re- turn as features of the 97 AHR Expo. The BAC Showcase will feature control products that run the gamut, from full-fledged building automation systems that marry HVAC with life safety systems and communicat

38、ions, to stand-alone unitary equipment control- lers. Many BAC systems offer the con- venience of Windows-based software, and compatibility with ASHRAEs BACnetTM building automation and control networking protocol and Lon- WorksTM. Custom systems and equipment dis- played will include programmable t

39、ime controls and energy management con- trols, variable-speed kitchen exhaust controls, automated VAV systems, data acquisition systems for clean rooms and other applications, individual controls for cubicles, noise and lighting controls, and much, much more. Computer software will include CAD progr

40、ams that cover the entire HVAC spectrum as well as service management and bidding software. Another returning feature is the spe- cial designation that clearly identifies Photo shows a section of the mechanical room at MOD-6. To improve main- tenance, the mechanical engineer modified the chillers, a

41、nd integrated over- head cranes and wide access bays into the plant design. Tour Continued from page I 7 coordination was another hurdle. For example, the monolithic ice storage tanks required that over 900 cubic yards (689 m3) of concrete be poured in one four-hour period. “Concrete trucks were bum

42、per to bumper, lining the street,” she said. But construction was completed in time to serve the Univer- sitys new 200,000 fi2 (18 580 m2) bio- medical research building that was being constructed simultaneously. The mechanical engineer for the plant was William (Bill) Trefz, who designed the plant

43、to stand up to 40 years of heavy use. To ensure reliability and durability, he customized the chillers by relocating their oil pumps, pumpout units, oil pipes, installation valves, and filters. He also integrated overhead cranes into the design to facilitate future upkeep, and used wide access bays

44、to accommodate removal of HVAC equipment. Piping throughout the plant is color-coded to allow for rapid identification. A very du- rable, light-weight fiberglass reinforced plastic (recently invented on the Univer- sity of Pennsylvania campus) was used to cover water-chilling tanks. The plant is ful

45、ly automated and uses an industrial-grade DDC system that enables the chiller plant to run at optimum efficiency, with little or no human intervention. The sensors and processors link the facility to the Uni- versity of Pennsylvanias Ethernet network, and transmit critical data into the university e

The offerings include resi- dential, commercial and industrial gas and oil-fired boilers and companion ductless air conditioners, and combination purge- balance shutoff valves. Items will include direct and indirect- fire water heaters

Power vent systems for gas and oil-fired equip- ment will be complemented by gas, oil and gas-oil burners, including lead-lag control systems. 12 ASHRAE Journal December, 1996 To say the least, the advantages are striking! More and more people are realizing the benefits of maintaining proper humidification. The problem, however, is it can be expensive to humidify. Well not anymore
