ASHRAE members have diverse interests so the Journal tries to cover a lot of topics
in each edition. We also look for articles and columns that will have broad appeal and
relevance.
Articles in this edition, for example, cover nine different HVAC&R technologies,
ranging from thermally active floors to refrigeration and just about
everything in between.
We’re able to do this partly because we’ve added standing columns,
which are shorter than full technical articles. But it’s mostly because of
the many volunteers who support the Journal. They set the Journal apart
from most publications.

OF SPECIAL NOTE is this month’s article on demand controlled
ventilation for commercial kitchens. This technology, say the authors, is poised to
become standard practice in commercial kitchen design because it minimizes the need
to condition large amounts of makeup air.
“Although it is known that exhaust hoods do not need to operate at full speed all day,
adoption of demand controlled ventilation technology has been sluggish,” say the authors.
What’s changing is that Standard 90.1-2010 and the ASHRAE Handbook both
recognize DCV as a key attribute of energy-efficient commercial kitchens. Also, the
technology is now offered by at least eight manufacturers.
The authors of this article are Don Fisher, P.Eng., Rich Swierczyna and Angelo Karas.
It covers types of DCV, the different ways to sense appliance use and cooking activity,
field monitoring data and more.
MUCH TIME, sweat and money is being spent to identify and replace R-22 with a
more environmentally friendly refrigerant. Significant disadvantages are associated with
all potential substitutes, says S. Forbes Pearson, Ph.D.
His article describes a way that ammonia can be used in low-charge systems that
maximizes efficiency while minimizing risks.
“There would appear,” says Pearson, “to be an opportunity to replace R-22 systems
in certain applications with well-tried low-charge ammonia systems that could be fully
automatic and even more efficient than the systems being replaced.”
BUILDING WRAPS, papers and housewraps always leak, says Joe Lstiburek, Ph.D.,
P.Eng., Fellow ASHRAE. The good news, he says, is small amounts of moisture are okay
as long as the wall can dry. This month’s column covers installing windows in housewrap
openings. As usual, there is a lot to learn.
Columns and articles also cover data centers, ground source heat pump performance,
refrigeration, IAQ and centrifugal compressors.
We hope members find many articles and columns of interest in this edition. Comments
and suggestions are always welcome.
