The Appliance Standards and Rulemaking Federal Advisory Committee (ASRAC) approved an agreement reached by manufacturers and energy efficiency advocates acting as part of a working group to set new energy efficiency standards for walk-in coolers and freezers (WICF).
According to ASHRAE, while many building rating programs exist worldwide, there is nothing in the industry that standardizes the contents of these programs, ensuring users are knowledgeable about what impacts their rating.
Ten online professional development seminars focused on commissioning, environmental quality, energy efficiency, HVAC applications, and standards and guidelines are being offered this fall by the ASHRAE Learning Institute (ALI).
The ability of engine-powered generators to start and supply standby power of acceptable frequency and voltage within 10 seconds of a utility outage has made these generators the standby power system of choice for a wide variety of facilities including mission critical.
Ziehl-Abegg has introduced its new ZAvblue impeller, which the company claims is up to 20% more efficient than other standard products. The company also says the bionic design of the new impeller requires significantly less space in the customer device. Equipment designers can now generate the current airflow with impellers that are one size smaller.
Johnson Controls has introduced the Quantech Air-Cooled Chillers. The company says the chillers offer up to 50% annual energy cost savings compared with the replaced chillers, have a low lifecycle cost, meet or exceed ASHRAE standards, and help earn LEED credit with a low refrigerant charge. Three models make up the Quantech chiller line. The QTC2 (15-50 tons) provides chilled water for all air conditioning applications using central station air handling or terminal units. The state-of-the-art installation uses tube and fin condensers, brazed plate evaporators, and scroll compressors.
Engineered Systems magazine’s May 2019 issue examines the role of HVAC systems and power in critical facilities via the University of Utah’s new, LEED Gold-certified Downtown Data Center; the role of codes and standards in mission critical facilities; why an engineer should consider a product’s functional requirements during the specification process; and much more.
