Experimental Testing and Modeling of a Dual-Fired LiBr-H2O Absorption Chiller (4457)
Sunday, June 24, 2001 8:00 AM - 10:00 AM
Tom A. Gee, Jiming Cao, Ph.D., James A. Mathias, Student Member and Richard N. Christensen, Ph.D., Member, The Ohio State University, Columbus, OH
A LiBr-H2O chiller was modified to utilize heat sources from natural gas combustion and/or from a hot fluid. This was achieved by replacing the original gas fired generator with a dual fired generator. Steam was used as the hot fluid. The generator of the chiller can be powered by each source separately or both sources simultaneously. Experimental investigation was performed to obtain capacity and COP of the original chiller and the modified chiller. The experimental conditions were closely modeled by a numerical program.

Techno-Economic Analysis of Absorption Chillers Powered by Low-Grade Heat, With and Without Vortex Induced Pressure Reduction in the Generator (4461)
Sunday, June 24, 2001 8:00 AM - 10:00 AM
Solomon S. Fineblum, P.E., Member, Megadyne, Inc., Stoughton, MA
Where only low grade heat is available for industrial absorption chiller installations, the systems are adjusted to operate at the available lower temperatures with a cooler generator. However, reduction in generator temperature results in reduced chiller capacity. Thus, the capital requirement per unit of capacity is increased when generator temperature is dropped. One approach to a lower generator temperature involves the lowering of generator pressure to permit an absorption chiller to function more efficiently with relatively cooler sources of waste heat.

Moderator: Kenneth R. Luther, Member, ITT Fluid Handling, Morton Grove, IL
Today's HVAC designer is faced with yet another variable…the power supply. With power interruptions becoming more frequent, what steps must the designer take to ensure that the client has a reliable source of power? Tools include thermal storage, UPS, co-generation, generation, building controls and operational choices. These choices do not come cheaply and may require a LCC analysis to justify the cost increase to the owner(s). This forum explores the effectiveness of options available and tries to answer the question “What measures must a designer take to ensure the HVAC system can tolerate such events without impacting the indoor conditions or processes?”

Commissioning Centrifugal Chiller Plants
Sunday, June 24, 2001 10:15 AM - 12:15 PM
Sponsor: TC 8.2 Centrifugal Machines
Chair: John Vucci, Member, University of Maryland, College Park, MD
Commissioning"new" centrifugal plants insures total integration of systems. It provides for both integrity of design operation and accuracy in energy consumption as intended by the designer. Simple startup of individual components does not integrate the"system" as intended, and many times results in improper plant operation and excess energy consumption. Failure to train operators initially can lead to continued failure of the system to perform as intended. Interactions within the plant are of critical performance."Retro-commissioning" reinforces original design intents and should be considered as a valuable tool to verify performance throughout the plant's life.

Issues in Window Condensation Resistance
Sunday, June 24, 2001 1:00 PM - 3:00 PM
Sponsor: TC 4.5 Fenestration
Chair: Anil Parekh, P.E., Natural Resources Canada, Ottawa, ON, Canada
The assessment of window condensation resistance by computer simulation presents challenges. Computer simulation is a tool of choice for engineers and designers as it quickly and accurately generates aggregate U-factor and SHGC. However, the assessment of condensation potential on room-side surfaces requires detailed mapping of surface temperatures. This has led researchers to investigate local heat transfer inside window frame cavities using 3D analysis. Another issue is the impact of window air leakage on condensation resistance. Research was conducted to reconcile the testing and simulation of these effects.

Cleanrooms are among the most expensive and sensitive types of design and construction projects. Construction costs can range from $500 - $2000 per square foot. Operating costs are also very high. The value of the product produced can eclipse the room costs by a factor of 10. Given the significant first cost and business value inherent in such facilities, it is important that such projects be properly planned in order to be properly executed. This seminar explores the issues involved in the planning stages of a cleanroom project, including critical items that require owner, engineer and operator agreement.

Chair: Paul M. Haydock, P.E., Associate, Carrier Corp., Indianapolis, IN
Residential and light commercial heating and air-conditioning systems are affected by several ASHRAE standards. These standards impact equipment efficiency, distribution effectiveness and efficiency, and indoor air quality. Standards 103 and 124 are being revised to address the changing state of the art in furnace, boiler and combination system design. Standard 152P is challenged by the variety of thermal distribution systems and the high amount of energy loss that occurs through leakage and heat transfer. Standard 62 is balancing the benefits of fresh air ventilation with energy usage and the impacts on gas appliances in the structure.

A Novel Total Heat Exchanger with Little Odor Transfer Using Ion Exchange Resin as a Desiccant (4462)
Monday, June 25, 2001 8:00 AM - 10:00 AM
Hiroshi Okano, Associate Member, Seibu Giken Co., Ltd., Koga-city, Fukuoka, Japan; Hiroshi Tanaka, Fukuoka Institute of Technology, Fukuoka, Japan; Tsutomu Hirose, Ph.D., Kumamoto University, Kumamoto-city, Kumamoto, Japan; Hiroshi Funato, Seibu Giken Co., Ltd., Koga-city, Fukuoka, Japan; Shu Ishihara, Fukuoka Institute of Technology, Fukuoka, Japan
Total heat exchangers are used in many countries as energy-saving devices for air conditioning in buildings and others. But they transferred odors because of accumulation of an offensive odor in the desiccant. We have investigated the cause of this problem and a possible solution. The result is to use a novel total heat exchanger with little odor transfer using ion exchange resin as a desiccant. The odor transfer properties of this novel total heat exchanger were analyzed in comparison with those of a conventional total heat exchanger using silica gel. A comparison was also made with other desiccants such as synthesized zeolite.

Air Crossover in Rotary Wheels Used for Air-to-Air Heat and Moisture Recovery (RP-862) (4463)
Monday, June 25, 2001 8:00 AM - 10:00 AM

Wei Shang, University of Saskatchewan, Saskatoon, SK, Canada; Maury Wawryk, Associate Member, Venmar CES, Saskatoon, SK, Canada; Robert W. Besant, P.E., Fellow, University of Saskatchewan, Saskatoon, SK, Canada
Crossover between the exhaust and supply air is measured and analyzed for a commercially available energy wheel with typical sliding seals on the rotary wheel faces and perimeter. It was found that a purge section could reduce, but not eliminate, carryover of exhaust gases to the supply due to wheel rotation only when the supply air pressure is greater than the exhaust. Increasing pressure differences between the supply and the exhaust decreased the ventilation air flow rate compared to the maximum supply side flow rate. This reduction was much larger for a wheel with a purge section than one without.

Experimental Validation of a Long Underground Railway Tunnel Ventilation System Under Emergency Operation Modes (4464)
Monday, June 25, 2001 8:00 AM - 10:00 AM
Kuan-Hsiung Yang, Ph.D.,and S. K. Lee, National Sun-Yat-Sen University, Kaohsiung, Taiwan, China
A full-scale experimental investigation has been performed to validate the emergency operation modes of a 7m (22966ft) long underground railway tunnel ventilation system. Test results indicated that the tunnel ventilation system can successfully provide the critical air velocity needed for a fire sized 13.6MW (12920Btu/s). However, the huge smoke reservoir beneath the tunnel ceiling may allow more time for egress and should be considered in planning for the emergency procedure. The underground railway system is now in commercial operation.

Particle Separation Efficiency of a Uniflow Deduster with Different Types of Dust (RP-878) (4465)

James J. Jetter, P.E., U.S. Environmental Protection Agency, Research Triangle Park, NC; Reynaldo Forte, P.E., Member, U.S. Environmental Protection Agency, Washington, DC; Francis R. Delafield, Arcadis Geraghty & Miller, Durham, NC
Refrigerant leak rates were measured for faulty air-conditioner evaporators removed from vehicles, and results indicated a range of very small to very large leaks. A survey of automotive air-conditioning service shops was conducted, and leakage scenarios were evaluated to determine possible worst-case conditions for inhalation exposure to refrigerant for vehicle occupants. Refrigerant concentrations were measured in passenger compartments of vehicles. Results from this work were utilized in a study to estimate the risk of exposure to refrigerants used in automotive air conditioning in the United States.

Sponsor: TC 1.4 Control Theory and Application
Moderator: Frank Shadpour, P.E., Member, GEM Engineering, San Diego, CA
This forum addresses the latest tools and techniques for the commissioning of HVAC direct digital control (DDC) systems. DDC systems often are utilized as a tool to commission the entire mechanical system within a building. The question is how do we commission the DDC system itself? The accepted methods and most commonly practiced rules of thumb in commissioning of DDC systems are discussed. Also, the difference between commissioning and validation for pharmaceutical projects are reviewed.

The Effect of Safety Factor on Pump Selection and Performance

Sponsor: TC 8.10 Pumps and Hyrdonic Piping
Chair: Brent Ross, P.E., Member, S.A. Armstrong Limited, Toronto, ON, Canada
The use of safety factors is common in engineering practice. The safety factors add a margin of safety to a design to ensure systems are not undersized but are capable of providing the desired minimum performance. Use of safety factors when sizing pumps on HVAC service is also common. Applying excessive pumping safety factors is often the reason that HVAC systems do not achieve the minimum performance intended. This symposium identifies the sources of safety factors, provides suggestions on appropriate application, identifies the effect on systems where excessive safety factors have been applied, and details practical site solutions to these issues after installation.

Best Practices for the Treatment of Steam Used for Humidification
Tuesday, June 26, 2001 8:00 AM - 10:00 AM
Sponsor: TC 3.6 Water Treatment
Chair: Hal Roth, P.E., Member, BetzDearborn, Trevose, PA
The use of steam for humidification presents many advantages to the user but the source of the steam used could be of concern. Chemical treatment of the steam to protect the condensate system may present a health risk to the building occupants. Alternative"clean steam" systems are available though these have a higher first cost. In presenting options for reduced chemical consumption it should be possible to provide steam from a central plant that uses treatment chemicals with minimal risk to the building occupants.

Sponsor: TC 4.11 Smart Building Systems; TC 1.4 Control Theory and Application
Chair: Michael Kintner-Meyer, Ph.D., Member, Battelle Pacific NW Division, Richland, WA
This seminar discusses a mechanism for exchanging and utilizing data across different application programs and data sources so that costly reformatting of input data can be avoided. This mechanism is called data modeling. A data model is a generic representation of an HVAC component and device or a service that can be recognized and processed in many application programs. Standards of data models are the foundation for interoperability across software tools. The seminar emphasizes how data modeling for operational aspects has been used and their potential impacts for the buildings operations, maintenance, and diagnostics.
