Where To Place Air-Cooled Chillers

Engineered Systems, Feb. 2017, by Kishor Khankari.

"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?

"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.

"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."

Alcatraz: One of the Largest Microgrids in the United States

U.S. Dept. of Energy, Jan. 26, 2017, by Mike Mueller.

"Each year, more than 1.5 million people tour Alcatraz Island to visit its iconic prison. But, most people don’t realize that this 22-acre site, located in the middle of the San Francisco Bay, is also home to one of the nation’s largest microgrids. The island is equipped with a solar-diesel hybrid power system that most visitors probably won’t notice."

Selecting Actuators for Industrial HVAC/Process Dampers

HPAC Engineering, Dec. 2016, by Bill Lampkin.

"If it is to accomplish its intended purpose, any damper installed in a HVAC system must be equipped with an appropriate actuator. The selection of an actuator for a specific damper requires consideration of a number of factors. This article examines the actuator-selection process. (Note: While damper actuators often go by other names, such as damper motors, damper operators, and motor packs, “damper actuator” is the appropriate terminology.)"

Boiler Tune-Up Cuts J.H. Baxter’s Annual Energy Costs By An Estimated $21,100

Energy Trust Blog, Jan. 5, 2017.
https://blog.energytrust.org/boiler-tune-cuts-j-h-baxters-annual-energy-costs-estimated-21100

"A Kewanee steam boiler is the backbone of J.H. Baxter & Co.’s wood-treatment facility in Eugene [Oregon]. But over time, the boiler’s fire tubes built up a layer of soot that decreased efficiency. The solution was a simple boiler tune-up that boosted efficiency by 8.5 percent, saving more than 41,000 therms per year. Not only did the project cut the facility’s annual energy costs by an estimated $21,100—90 percent of the cost of the tune-up was paid for through Energy Trust of Oregon’s 90 by 90 industrial operations and maintenance offer."

LEDs in Yerba Buena’s Vegetative Room Deliver a 9-Month Payback

Energy Trust Blog, Jan. 4, 2017.
https://blog.energytrust.org/leds-yerba-buenas-vegetative-room-deliver-9-month-payback/

"Yerba Buena, a CleanGreen™ Certified cannabis grower in Hillsboro [Oregon], prides itself on being a good steward of the Earth. Part of the company’s commitment to energy conservation involves looking for ways to reduce energy use. In an industry known for energy intensity, Yerba Buena became one of the first recreational cannabis growers to take advantage of Energy Trust’s technical assistance and cash incentives when the company replaced T5 fluorescent lighting in its vegetative room with tubular LEDs."

Biomass Test Delayed at Boardman Coal Plant

East Oregonian, Dec. 30, 2016, by George Plaven.

"Portland General Electric had planned to conduct a full-day test burn at the plant using nothing but woody debris by the end of December. However, as winter weather had Oregonians cranking up the heat, PGE needed all resources on deck to keep up with the surge in electricity demand."
