“2011 Thermal Guidelines for Liquid Cooled Data Processing Environments” creates data center classes for liquid cooling that can enable fulltime economizers for a number of applications in many climates, according to according to Don Beaty, chair of the Publications Subcommittee of ASHRAE’s Technical Committee (TC) 9.9, Mission Critical Facilities, Technology Spaces and Electronic Equipment.
The truth is, you could have an extremely fruitful trip to the AHR/ASHRAE host city next month and never set foot on the Expo floor. Between the paid ASHRAE courses and all the free sessions hosted by various groups over at the Expo (see conveniently integrated list below), attendees may have some hard choices as they balance new products with hot topics.
Registration is open for ASHRAE’s 2012 Winter Conference in Chicago, where attendees will have the chance to discuss and examine the latest topics in the building industry as well as participate in technical tours, attend ASHRAE Learning Institute courses, earn professional credits, and obtain ASHRAE certifications.
Commercial and high-rise residential buildings, including federal buildings, must now meet requirements in ASHRAE/IESNA’s 2007 energy efficiency standard under recent rulings issued by the United States Department of Energy (DOE) that finds the standard saves more energy than the 2004 version.
There’s
a concept, eh? The author takes a comparative discussion of chiller
technologies and options, and he places it squarely within the current events
context of domestic energy sources, the utility rate landscape, and thermal
efficiency. Read this and then look for Part 2 in the near future.
From sidewalks to hospital entrances and helipads, these systems are becoming a more common part of a project’s mechanical infrastructure. Examine differences between ASHRAE’s old and updated classifications, then review design considerations such as heat of evaporation, heat loss to the atmosphere, and back and edge losses. Tubing, spacing strategies, and controls round out the primer.
