Liebert: Managing Extreme Heat - Cooling Strategies For High-Density Systems
Date: February 24, 2010
As computer manufacturers pack more and more processing power into smaller packages, the challenge of data center cooling becomes more complex - and more critical. New servers and communication switches generate as much as ten times the heat per square foot as systems manufactured just ten years ago.. This white paper describes the new strategies and technologies that must be implemented to provide the cooling high-density systems require for reliable operation.

Johnson Controls: Creating a Safe, Sustainable Community in a Challenging Economy
Date: December 9, 2009
While new technology advancements are helping
communities execute services faster and more efficiently, many local
governments are having trouble finding the funds to implement them.
According to Gartner Research, virtually all IT project investments
within local governments will undergo a value-for-money reassessment
beginning this year. Many will take advantage of the new economic
stimulus funds from the American Recovery & Reinvestment act. But
will the stimulus offer enough help?
This white paper addresses
how technology is now able to deliver meaningful ROI data and why a
well-planned implementation of technology initiatives will deliver the
strongest public value impact. The strategy is showcased in success
stories from two local governments who were able to serve their
constituents by making their communities more efficient, even when
financing looked impossible.

Lochinvar: Lime Scale Accumulation: The Energy Thief
Date: December 9, 2009
Water is used in a wide range of commercial
applications. Every day, businesses and facilities heat water to serve
the needs of their customers and patrons. While restaurants,
laundromats, hotels, and car washes all require very large amounts of
hot water to stay in business, nearly all companies rely on hot water
in one way or another. Each year, a significant portion of their
overhead is allotted to the fuel required to heat water, and everyday
that allotment becomes slightly larger. However, many do not realize
what they lose each year due to the negative by-products of heating
water such as lime scale buildup, which cause efficiency losses,
malfunctions, total equipment failure.

ECO-MAX™: Adsorption Chillers for Global Cooling
Date: November 12, 2009
Adsorption chillers are a unique approach to
achieving air conditioning and process cooling. Adsorption chillers are
driven by hot water rather than from large amounts ofelectricity
like conventional air conditioners. Capturing and using waste heat
could be one of the largest conservation and green house gas reduction
opportunities. Heat recovery is an opportunity to recycle energy that
is typically wasted.

Electro Static Technology: Shaft Grounding - Fulfilling the Promise of Variable Frequency Drives
Date: October 7, 2009
With the rising cost of energy, the use of
variable frequency drives (VFDs) is growing at an increasing rate. By
optimizing the frequency of a three-phase alternating-current (AC)
induction motor's voltage supply, a VFD controls the motor's speed and
torque while providing energy savings. And, these energy savings can be
quite substantial - 20% or more - making VFDs a "green" solution as
well as a wise money-saving investment.

Steam Accumulators and Steam Boiler Response to Load Changes
Date: September 18, 2009
Steam load management is often neglected during
the design phase of a steam delivery system. As a result, in the case
of a boiler that serves steam-using equipment that cycles like an
autoclave or sterilizer, steam quality and quantity at start up may
suffer significantly. Understanding the significance of the events
inside and outside the boiler pressure vessel during a rapid steam load
demand period and choosing the correct design enhancements will reduce
the consequences of rapid depressurization.

Maximizing Heating System Gains with Hybrid Boiler Plants
Date: September 18, 2009
A hybrid boiler plant is defined as a hydronic
heating plant combining condensing and noncondensing boilers. This
system is designed to take advantage of the best properties of both
boilers. Through the proper design and selection, 100% of the potential
energy savings can be realized with a possible installed cost savings
of one third to one half of the cost compared to an all condensing
plant.

ECO-MAX Adsorption Chillers for Global Cooling
Date: August 17, 2009
Adsorption chillers are driven by hot water
rather than by large amounts of electricity like conventional air
conditioners. This hot water may come from any number of industrial
sources, including waste heat from industrial processes, prime heat
from solar thermal installations or from the exhaust or water jacket
heat of a piston engine or turbine. Organizations that could benefit
from adsorption chillers include food and beverage processing;
chemical, plastic, rubber, paper and cement manufacturing; hospitals;
hotels; and school campuses.

Managing Extreme Heat: Cooling Strategies For High-Density Systems
Date: April 20, 2009
As computer manufacturers pack more and more processing power into smaller packages, the challenge of data center cooling becomes more complex - and more critical. New servers and communication switches generate as much as ten times the heat per square foot as systems manufactured just ten years ago.. As these new systems are installed alongside previous generation systems, they create hot zones within the data center that cannot be effectively managed using traditional approaches to cooling. New strategies and technologies must be implemented to provide the cooling high-density systems require for reliable operation.
