Cooling Towers Offer Data Centers Water and Energy Savings

Chiller & Cooling Best Practices, Mar. 2017, by Douglas Bougher and Kent Martens.

"The number of data centers in the United States continues to grow in response to the enormous amount of digital information stored and streamed. The massive computer power within these data centers generates heat, making efficient cooling a key building system requirement. Evaporative cooling towers are an integral part of many data center cooling systems. Recently some have questioned the use of cooling towers, citing water scarcity to bolster their arguments. But a thorough examination of water use for local onsite cooling towers compared to water use to generate power at regional fossil fuel power plants reveals surprising results."

Lunching and Learning: Food for Thought on a Geothermal-Heat-Pump-System Design

Heating, Piping, Air Conditioning, Jun 2016, by Jeffrey Newcomb.

"In the article, Fred, a mechanical engineer, explains his unusual design for a campus chilled-water system to William, a civil engineer. William asks questions and makes observations, system diagrams scribbled on napkins are exchanged, and Fred is left with a new way of thinking about his design. Sound familiar?"

Evaluating Chilled Water Cooling System Components

"While the chiller is the heart of a chilled water system, its support system of components and controls are equally critical to maintain and manage to ensure the highest system efficiency levels are attained. Emphasis is often placed on the chiller since it is the most visible and typically the highest energy element of a chilled water system. Yet, if you look beyond the flanges, there’s an opportunity to improve delivery of chilled water to the airside or process loads and maximize system efficiency."

Saving Water with Cooling Towers

ASHRAE Journal, Aug 2015, by Frank Morrison.
http://bookstore.ashrae.biz/journal/download.php?file=2015Aug_020-033_Morrison.pdf

"Saving water with cooling towers. At first glance, this statement seems counterintuitive. Cooling towers save energy but aren’t they major users of water? This article will help readers understand the critical role evaporative heat transfer systems play in a sustainable environment, explore how water is consumed in such systems, and review the strategies that help minimize the use of both water and energy."

10 Cooling Tower Maintenance Tips

Air Conditioning, Heating, Refrigeration News, June 22, 2015, by Baltimore Aircoil Co.
http://www.achrnews.com/articles/129904-cooling-tower-maintenance-tips

"A well-maintained unit will continue to function at the original optimum efficiency. Over time, a neglected cooling tower’s leaving water temperature will increase, raising energy costs by up to 6 percent for every 2°F increase. However, a well-maintained cooling tower will continue to function at the original optimum efficiency, keeping energy costs low. These simple preventive cooling tower maintenance tips can help users save up to 15 percent on electricity costs. Routine maintenance also helps to conserve water and extend the operating life of cooling equipment."

Methods of Calculating Water Recovery From Air-Conditioning Cooling Coils, Part 2 of 2

HPAC Engineering, May 2015, by William G. Acker.
http://hpac.com/air-conditioning/methods-calculating-water-recovery-air-conditioning-cooling-coils-part-2-2

"Last month, in Part 1 of this article, we evaluated four equations used to determine the amount of water vapor removed from cooling coils in condensate-recovery applications. The accuracy of those equations varies, as some calculate only the removal of water vapor entering with the outside-air intake. This month, we will discuss more-accurate methods of calculating water-vapor removal and calculating the removal of all water-vapor loads by a cooling coil."

Methods of Calculating Water Recovery From Air-Conditioning Cooling Coils, Part 1 of 2

HPAC Engineering, Apr. 2015, by William G. Acker.
http://hpac.com/air-conditioning/methods-calculating-water-recovery-air-conditioning-cooling-coils-part-1-2

"In traditional building cooling, air passes through chilled cooling coils in air-handling units prior to entering a facility. As air passes over the coils, moisture in the air condenses into water on the coils. The water drips into a collection pan below and is sent to a sewer drain. Today, however, particularly in areas where water is scarce and rates are high, many building owners are collecting this water and using it to replenish cooling towers for irrigation and other uses."

Cooling Tower System Audit for a Tough Mining Compressed Air Application

Chiller & Cooling Best Practices, Mar. 2015, by Tim Dugan.
http://www.coolingbestpractices.com/industries/manufacturing/cooling-tower-system-audit-tough-mining-compressed-air-application

"The goals of this article are to describe a large mining compressed air system case study and from a cooling perspective, discuss the limiting factors and performance issues of each of the cooling subsystems, and recommend improvements to the case-study project that will make the system much more reliable."
