Carrier Corp. of Syracuse, N.Y.; and the U.S. Air Forces Phillips Laboratory at Ed- wards AFB, Calif. The teams engineers are developing hydrostatic bearings that c

22、an replace the current rolling-element bearings used in rocket engines, and the hydrodynamic journal bearings used in air-conditioner chiller units. Hydrostatic bearings use the working fluid pumped into the small clearance between the bearing and shaft. The fluid enters from six or more openings ar

23、ound the perimeter, which keeps the shaft centered and reduces friction. According to ARPA, the combined use of hydrostatic bearings and ozone- friendly refrigerants could reduce the annual use of lubricating oil by 72,000 gallons. Currently, oil is used to ensure proper lubrication of the refrigera

24、nt compressors gears and bearings. But the oil contaminates refrigerants and re- duces heat transfer efficiency. In addition to reducing rehgerant con- tamination and improving heat transfer ef- ficiency, hydrostatic bearing also could minimize mechanical energy losses, reduce fabrication and assemb

Dono- van, president and chief executive officer of ABB Inc., died on April 3, while on a mission

32、to Bosnia with Secretary of Com- merce Ron Brown. He was 54 and lived in Fairfield, Com Donovan was named president and chief executive of- , I ficer of ABB Inc. in January 1994. In ad- dition to being CEO of ABB Inc., he was executive vice pres- ident of ABB Asea Brown Boveri Ltd., Zurich, in which

33、 ca- pacity he oversaw the Groups opera- tions in the Americas. He was based in Norwalk, Conn. As president of ABB in the United States, Donovan was instrumental in . promoting exports to Eastern Europe, China and the Far East. As head of its Americas region operations, he also di- rected an integra

34、tion and expansion of the companys trade throughout North and South America. Donovan had also been the president of ABB Power Plant Systems, ABBs U.S. boiler and turbine operations. He joined ABB in 1992 after two years at Foster Wheeler, Perryville, N.J., as vice president and group executive of it

35、s En- ergy Equipment Group, with responsi- bility for companies in the United States, Canada and Spain. Before that he spent 17 years at Babcock and Wilcox. An alumnus of the U.S. Military Academy at West Point, Donovan spent ten years in the U.S. Army Corps of En- gineers, with assignments in the U

36、nited States, Thailand and Vietnam, and re- tired as a lieutenant colonel in 1991. He held a masters degree in nuclear engi- neering from Massachusetts Institute of Technology. He is survived by his wife, Margaret Fitzsimmons Donovan, of Fairfield, and by two children: Kevin Edward, 29, of Toronto,

37、and Kara Siobhan, 25, of Ak- ron, Ohio. Meadowland Contract Is Honeywell Record MINNEAPOLIS-The governing body of the Meadowlands Sports Complex in New Jersey recently signed an ener- gy retrofit agreement with Honeywell thats worth almost $45 million, the largest amount in Honeywell Home and Buildi

38、ng Control history. The 750-acre complex includes the 76,000-seat Giants Stadium, the 40,000-seat Meadowlands Racetrack, the 21,000-seat Continental Airlines Arena, and about 26 ancillary facilities. The 15-year contract provides for updating and retrofitting the facilities heating, cooling and ligh

39、ting systems, and upgrading the existing building management systems to the Honeywell EXCEL 5000( direct digital control system. As part of the agreement, Hon- eywell will convert the facilities elec- tric heating and cooling to natural gas, garnering utility incentives that will create an annual re

40、venue stream for up to 15 vem. Thermal Care introduces the new FC 4000 Series Cooling Tower. Now you can get the same great features and performance of our proven FC 5000 Series tower in an all new lower tonnage FC 4000 Series version. All FC Towers feature one-piece, fiberglass, leak-proof basins,

41、permanently lubricated motor bearings and totally nonferrous construc- tion. In addition, Thermal Care offers an exclusive 5-year warranty on the entire tower including the motor.

ASHRAE Journal May 1996 (Circle No. 11 on Reader Sewice Card) 13 ASHRAE TITLE*JOURN 38-5*UPHS 96 m 0759650 05215b9 bb9 m Condenser Water Flow Rates This is a response to Wayne Kirsners article, “3 GPM/Ton Condenser Water Flow Rate: Does It Waste Energy?” (ASHRAE Journal, February 1996). Th

43、e article makes a valuable contribution to our understanding of how chiller opera- tion is affected by changing condenser water flow rate. Kirsner refers to three prior ASH- RAE articles and papers on this sub- ject, all of which concluded that conventional condenser flow rates of 3 gpm per ton are

44、not economically justi- fied, and that the use of lower flow rates will result in lower total owning and operating costs. Kirsners article con- cludes that 2 gpm per ton or 1.5 gpm per ton does not necessarily result in the lower power consumption. My comment is that his criteria is power consumptio

45、n only, whereas the papers he compares his results to considered total owning and operating (life cycle) costs, not just power consumption. As a result, his findings are not comparable. I would hope that Kirsner will apply his considerable talents to a sequel which considers total life cycle costs,

46、which is the normal criteria for system selec- tion. Since the referenced articles were published, advances in chiller design, revised electric demand charges and use of different refrigerants have made a contemporary update appropriate. (I am the author of the January 1988 ASHRAE Journal article wh

47、ich was the earliest of the three references quoted by Kirsner). Kirsner states that, for short-coupled systems, 3 gpm per ton has lower peak energy draw (demand) than 2 gpm per ton. I do not disagree with that statement as far as it goes. I would only comment again that energy is only part of the s

48、tory. My 1988 findings were that 2 and even 1.5 gpm per ton resulted in lower total owning and operating cost. I would invite Kirsner to expand his study to consider total life cycle costs. Kirsners methodology of reselecting sizes of cooling tower, piping and pumps for varying flow rates results in

49、 uneconomical selections of equipment. He does not seek optimal combinations that result in best use of resources, or that result in authentic comparisons between one flow rate and the other. To illustrate this point, I will comment below upon how he re-sizes the cooling tower as he reduces condenser flow rates. I have similar quibbles about his re-sizing of piping and pumps, but will omit detailed review of these items in order to keep down the length of this dis- cussion. In re-sizing the cool
