Designing a Dedicated Modern Wine Cooling System

Chiller & Cooling Best Practices, Mar. 2017, by Kevin Trowhill.
http://www.coolingbestpractices.com/industries/beverage/designing-dedicated-modern-wine-cooling-systems

"The temperature of wine must be kept stable throughout its production and storage in order to ensure final product quality that is acceptable for distribution and sale, and so cooling systems are an integral component of wine production. In wineries, the entire harvest can be destroyed by a temperature fluctuation during processing or storage, leading to catastrophic consequences for wineries. Cooling systems must meet three main criteria in order to be effective in wine production and storage applications: the cooling systems must be able to achieve the ideal temperatures for wine production processes; they must deliver consistent, reliable operation; and they must be well-designed for safe, convenient use."

Energy Efficiency: A Little Knowledge Goes a Long Way

Automation World, Mar. 2017, by James R. Koelsch.
https://www.automationworld.com/energy-management/energy-efficiency-little-knowledge-goes-long-way

"There has been a lot of talk in industry about energy efficiency in manufacturing facilities, but the realities of high cost and limited returns have stymied action. Some best practices, though, could tip cost calculations in favor of moving forward."

Ultrasonic Flow Meters Improve Biogas Measurements

Pumps & Systems, Feb. 2017, by Dick Laan and Rick Lowrie.

"As interest in biogas grows, industry is paying more attention to measuring biogas flow, which has long been a challenge in process measuring technology. While high water and carbon dioxide (CO2) content makes biogas a demanding medium and a difficult measuring task, a new generation of ultrasonic flow meters is helping to make biogas measurements stable and manageable. One type uses the time transit differential method to guarantee flow measurement with a high degree of long-term stability regardless of the gas composition."

Best Practices for CHP Development

Power Engineering, Feb. 2017, by Thomas G. Adams.
http://www.power-eng.com/articles/print/volume-121/issue-2/features/best-practices-for-chp-development.html

"Combined heat and power (CHP) projects promise many benefits to a wide array of large energy users, and CHP has a long history of adoption and success in many industries. Despite its wide adoption, many energy users considering the development and installation of a CHP project face a set of tasks and challenges that they are not always fully equipped to handle since their primary business is usually quite different from power and thermal energy production. By focusing on best practices from the start of project development, to execution, and on to long term operation and maintenance, new owners of CHP systems can mitigate risks and maximize the chances of success for their project."

Compressed Air System Commissioning Part 1: Why Do It?

Compressed Air Best Practices, Feb. 2017, by Tim Dugan.
http://www.airbestpractices.com/system-assessments/compressor-controls/compressed-air-system-commissioning-part-1-why-do-it

"“Retro-Commissioning” (ReCX) of compressed air systems has become a trendy activity with many utility demand-side-management programs emerging in the last 5-10 years.  This is intended to be the process of “tuning up” a compressed air system, getting low cost savings from mostly adjustments and repairs.  The term was borrowed from the building/HVAC industry, where it means to get a system operating as it was originally “commissioned”."

Steam Turbine Retrofits: Methods to Extend Turbine Life and Improve Performance

Power Engineering, Feb. 2017, by Muhammad Saqib Riaz. http://www.power-eng.com/articles/print/volume-121/issue-2/features/steam-turbine-retrofits.html "A steam turbine is designed and optimized for a specific set of steam conditions. After long term operations either the steam path components deteriorate or due to changes in steam conditions, a re-optimization of the steam path components is required to regain higher turbine performance. Steam Turbine retrofits are performed to achieve various goals such as improved turbine efficiencies, heat rate or power output. Retrofits are also performed to address turbine reliability and or maintenance issues. Availability of newer technologies and materials for steam path components can be utilized to not only increase steam turbine performance, but also to extend maintenance intervals, and extend life. Retrofits can also accommodate required changes to the thermal cycle based on emerging needs of the power plant. The effectiveness of the retrofit is achieved by ut ... Read the rest of entry »

Optimized Energy Recovery

ASHRAE Journal, Jan. 2017, by Marvin Kirshenbaum.
http://ashraecok.org/images/downloads/Technical_Literature/journal_2017_01_optimized_energy_recovery.pdf

"This article addresses extending the application of waste heat recovery to both reheat and primary heating, allowing for a heat reclaim system no longer restricted to seasonal operation."

Where To Place Air-Cooled Chillers

Engineered Systems, Feb. 2017, by Kishor Khankari.
http://www.esmagazine.com/articles/98146-where-to-place-air-cooled-chillers

"Warm discharge plumes sweeping back into air-cooled condensers is nobody’s idea of an ideal performance environment. This CFD study shows how wind speed, wind direction, spacing between chillers, and separation from adjacent buildings all factor into the conversation about the best defense against unwanted hot air."

Fluid Cooling In Data Centers — If Not Now, When?

Engineered Systems, Jan. 2017, by Kevin Dickens.
http://www.esmagazine.com/articles/98105-fluid-cooling-in-data-centers-if-not-now-when

"Trends don’t always follow the expected path (or timeline), but the basics remain the basics and increased cabinet density remains inevitable. Let’s revisit the progress of liquid in data center strategy and the tenets of a future-proof(ish) hybrid design for today."

Design of a High-Temperature-Hot-Water-Plant Expansion

HPAC Engineering, Jan. 2017, by Eric Chrencik.
http://hpac.com/heating/design-high-temperature-hot-water-plant-expansion

"There are four main components of HTHW-plant design:
  • HTHW-generator selection.
  • Pump selection.
  • Consideration of system expansion and makeup.
  • Stress analysis and piping layout.
This article discusses all four for a recently completed HTHW-plant expansion at George Mason University in Fairfax, VA."
