Did you know milk dust and flour, among other dusts, are explosive? Combustible dusts require the use of dust collectors. Join Chris Jester, Associate Member ASHRAE, and Technical Editor Rebecca Matyasovski as they discuss the design of dust collector systems, including air velocity and duct sizing, safety considerations, motor requirements and relevant codes.

Join Mike Gallagher, P.E., Life Member ASHRAE, and Technical Editor Rebecca Matyasovski as they discuss the monthslong saga to fix what started out as a small gas leak in the furnace room of his church—just before Christmas.

Andy Pearson shares some of the upheaval in which scientist Sadi Carnot performed his work, including for the science we now call “thermodynamics.”

Hamed Yassaghi, Ph.D., Associate Member ASHRAE, talks about data center IECC 2021 compliance strategies in hot climates with air-cooled chillers.

The amount of time students spend in school corridors is small compared to time spent in classrooms. But Lisa Ng, Ph.D., Member ASHRAE, believes it’s important for school corridors to be ventilated beyond what’s currently required by ASHRAE Standard 62.1-2022. She joins Journal Technical Editor Rebecca Matyasovski to explain why.

During the pandemic, many businesses adopted a “work from home” model to ensure the safety of their staff. Now, that model may be here to stay and along with it an increased appreciation for IEQ in homes. Join Bill Healy, Ph.D., Member ASHRAE, and the Journal’s technical editor Rebecca Matyasovski as they discuss how ASHRAE can help identify opportunities to improve IEQ in residential workspaces.

Join Bill Ryan, Ph.D., P.E., Fellow ASHRAE, and Technical Editor Rebecca Matyasovski as they discuss Ryan’s upcoming article covering marginal carbon factors and how electric production is controlled and managed. The technical feature will appear in the January 2024 print issue of ASHRAE Journal.

“There are so many things that you do not know down in the ground. So, in order to be accurate, a computer program must have all the necessary input data, and much of that input data is not available when the formation... [and the heat transfer are] complex,” says Steve Kavanaugh, Ph.D., Fellow/Life Member ASHRAE. Join Kavanaugh and Technical Editor Rebecca Matyasovski as they chat about the need for more field data for ground source heat pump design models.
