HVAC systems account for upwards of 40% of a building's annual energy usage, and high efficiency equipment is one way of reducing the annual utility costs. However, understanding the different styles of duct system and their impact on leakage is key to realizing maximum system efficiency. This paper spells out some duct sealing basics and more.
The sheer magnitude of energy, boiler chemicals, and water lost in wasted condensate in many steam humidification applications is staggering. Until recently, the typical condensate management strategy included a floor drain. This paper explains how condensate waste can be eliminated, and short absorption and unprecedented energy and water savings can be achieved, thanks to a steam dispersion panel.
Although data centers can now pack more processing power into less real estate, high-density computing environments can be a huge drain on operating budgets, for several key reasons. Top 10 Ways to Save Energy in Your Data Center explains how even a small data center can save tens of thousands of dollars through smart choices in equipment and best practices.
Electro Static Technology’s White Paper focuses on mitigating the variable frequency drive- (VFD-) induced shaft currents that can be extremely damaging to motor bearings, and a new technology that employs a circumferential ring of conductive micro fibers to discharge harmful currents and provide a low-cost solution to the problem.
Technology Contracting: Designing Systems for Efficiency and Interoperability, explores the advantages of engaging specialized technology contractors in design, construction, commissioning, and even O&M. Technology contracting involves assigning a single point of responsibility upfront to bring an enterprise-wide perspective to managing the planning, design, installation, integration, commissioning and service of low-voltage systems, business applications and supporting infrastructure. Technology contracting can save time, reduce risk and decrease construction and operating costs while ensuring that technology is deployed and integrated in an orderly manner to achieve desired outcomes.
Plenum integrity is one of the most important aspects of designing, constructing and maintaining an underfloor air delivery (UFAD) system. It is vital that the entire design and construction team does their part to ensure the underfloor plenum is sealed properly. Read on for plenum seal integrity guidelines based on lessons learned through working on a wide range of UFAD projects.
As electricity prices and IT power consumption continue to rise, IT-related energy costs are getting increased scrutiny. Cooling accounts for approximately 37% of electricity usage within a well-designed data center and, in many cases, represents a significant opportunity to reduce IT energy costs. This paper delves into cost cutting measures and much more.
Progress in AC drives technology is making life ever easier for operators, and this submission examines how through meeting increasing demands for flexibility, reliability and ease of use, the company has come up with a number of solutions to make life simpler and cheaper for its customers.
There’s more to “quality sound” than low sound levels. This paper sets out to clarify the most commonly used descriptors of sound, including sound power, sound pressure, octave bands, noise criteria (NC), room criteria (RC) and the A-weighting network (dBA). It also examines ways of specifying desired acoustical comfort and emphasizes the importance of specifying acoustical performance based on an analysis that converts sound power to sound pressure.
Moore Industries' latest white paper covers the basics of MODBUS and then delves deeply into the use of the protocol in process and automation applications. It also covers Ethernet connection and much more.
Chilled water remains a popular cooling medium for data centers; however, leaks in the piping systems are a threat to system availability. High density computing creates the need to bring chilled water closer than ever before to the IT equipment, prompting the need for new high reliability piping methods. This paper discusses new piping approaches, which can dramatically reduce the risk of leakage and facilitate high-density deployment. Alternative piping approaches and the advantages over traditional piping systems are described.
ABB has released a technical paper focusing on reducing adjustable frequency drive (AFD)-caused harmonics at partial-load conditions. The paper explains the benefits of a new built-in harmonic mitigation technique for pulse width modulated (PWM) AC AFDs.
American Power Conversion’s (APC’s) white paper #130, entitled “The Advantages of Row and Rack-Oriented Cooling Architectures for Data Centers,” contrasts room, row, and rack architectures and asserts that row-oriented cooling will emerge as the preferred solution for most next generation data centers.
Contemporary Controls has released a new white paper titled "The ABCs of (Internet Protocol (IP)," which covers the basics of IP including what an IP is, routers and hosts, IP headers, and more. It also includes several diagrams to help explain IPs and how they work.
Emerson Climate Technologies has released a detailed white paper entitled, “Energy-Saving Incentives for High-Efficiency Scroll Compressors in Walk-In Coolers,” authored by Harry Moresi, a senior engineer of Emerson Climate Technologies’ Design Services NetworkSM division, and Brian Buynacek, a senior consultant for the Design Services Network. This article delves into, among other things, how, by following the lead of the dairy industry, the foodservice industry in 13 states alone could save nearly $100 million annually in energy costs by replacing traditional reciprocating compressors in walk-in coolers with more efficient scroll compressors.
Sanuvox Technologies, designer of a line of residential and commercial UV Air Purifiers that address IAQ and “sick buildings,” has released a paper that details UV effectiveness on airborne contaminants such as avian flu virus and biohazards. The UV technology has also been validated by the U.S. EPA and The National Homeland Security Research Center (NHSRC) in their findings on “Biological Inactivation Efficiency by HVAC In-Duct Ultraviolet Light Systems.”
In this White Paper, Belimo analyzed two virtually identical buildings to demonstrate that significant cost benefits can be achieved by opting for pressure independent valve control over standard two-way control with a separate balancing valve.
ClimateMaster’s White Paper #2, “Treatment of 100% Outside Air,” reviews the unintended side effects of increasing outside air volumes, and describes a way of solving or preventing these indoor air problems without a need to change air handlers.
System Sensor, with the assistance of Schirmer Engineering Corporation, has produced this executive summary detailing “Smoke Detector Spacing on Level Ceilings with Beams and Joists.”
Moore Industries, a supplier of Fieldbus power supplies, device couplers, and systems for both Foundation Fieldbus and Profibus, has published a white paper designed to help engineers acquire a more comprehensive understanding of how Fieldbus works.
James B. (Burt) Rishel, owner and manager of Pumping Solutions, LLC, has authored a paper focused on the Patterson Pump Company’s HSC pumps, which are designed for the HVAC industry and offer selections for chillers in the range of 300- to 2,500-ton capacity. Pumping Solutions is a firm devoted to the evaluation of water systems and the development of variable speed pumping stations designed to achieve efficient pumping with reduced wear on centrifugal pumps.
Lennox has released a brief white paper in which it explains how its T-ClassTM rooftop units lend themselves to quick and easy emergency replacements. The paper also expands upon some of the line's additional benefits.
