ECO-MAX™: Adsorption Chillers for Global Cooling

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

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

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

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

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.

Best Practices for Power Equipment Startup

In order for the electrical power distribution systems within data centers and related facilities to operate properly as designed and intended, it is extremely important that care be given to the commissioning and startup of the electrical equipment via effective and reliable methods. This paper describes the need for a systematized program for new power equipment startup and the best practices and pitfalls that exist with regards to power equipment startup. This paper will also provide an overview of important items and issues that should be focused upon as part of reliable power equipment start up procedures and processes.
