Today, I am at a seminar hosted by TRS, one
our
chapter Platinum Sponsors. The central
theme of this
seminar is the importance of humidity control.
Back in
the day when lighting and equipment loads
were 3-5
W/Sqft or more and ventilation was 5
CFM/person,
humidity was rarely a problem.
Indoor humidity is a critical component of IAQ. Codes and standards require that humidity not exceed 60% in most spaces. Most institutional HVAC systems directly control RH by maintaining constant discharge temperatures or by directly dehumidifying OA. For most light commercial and residential HVAC designs, humidity is not controlled. It is only an accidental consequence of system operation if indoor RH is within accepted limits. More likely is the situation with low indoor sensible loads resulting in compressor cycling operation, and significant amounts of humid outdoor air being continuously introduced. This is the recipe for high indoor humidity. .The ASHRAE community needs to be more aware of the need to directly control humidity. There are relatively cost effective equipment and designs available now to better manage RH. These products and designs need to become mainstream every day design. The result would be better indoor air quality at a lower HVAC system cost per square foot. Long Range Planning Dates 1. ASHRAE President, Bill Harrison Here on Monday, April 27, 2009 2. Spring Golf Outing - May . |

The March LUNCH meeting at the Moose Cafe
was well attended and several new faces were
in attendance. The lunch was generally well
received by country cookin fans, but a few
expressed a desire for some healthier
options. We will take that into consideration
for the next lunch meeting.
Hank Saye gave us an overview of Industrial Ammonia Refrigeration Systems complete with many pictures and much appreciated anecdotal tales from the industry. Although Hank did not mention it, I noticed in this month's ASHRA Insights an articles on "New Roles for Natural Refirgerants" which sites an updated position on Ammonia Rfrigerants. You can see it at http://www.ashrae.org/docLib/20 0622793710_347.pdf. |

This article is the Part 6 in a series titled:
The Post War Days (1945-1960)
In the late 1950's, home air conditioning, like any technology, had its detractors. Some people considered the use of air conditioning technology to satisfy private wants, while public needs were ignored, a deformation of American value. In 1958,John Kenneth Galbraith argued that once wants had been created by producers and advertising, it was foolish to believe that the public would ever willingly "un-want" them again, even in the times of national crisis. This information is from the ASHRAE Journal article "A History of Air Conditioning in the home" by Mike Pauken, PE dated May 1999. |

Shifting domestic and world economics along with
continuing advances in technology are going to result
in energy options never considered feasible in the
past. Advances in energy sources such as solar,
wind, fuel cells, high performace batteries and
hydrocarbon alternatives like ethanol are the subject
Many of these technologies are near enough to being economically viable and are getting a lot of funding from corporate and government sources. However, there are other potentially viable technologies which are further off, but need to be funded to progress to the stage where they are viable. ASHRAE Research is one such avenue which the North Piedmant Chapter has made a concerted effort to support. Because North Piedmont has been such a good donor in the past, we have a fairly high goal for Research Promotion ($27,000). Donations received to date from corporate sponsors, the fall golf tournament and the holiday fund raiser total about $15,000, so we still have a ways to go. This is where all of our members come into play. We look forward to the May golf tournament as one source of Research revenue, but it's corporate and individual member donations that make the biggest impact. So please be generous when asked to help for this worthy cause. Corporate sponsors who have already paid or pledged support this year are: Hoffman and Hoffman Inc (Pledged) Benner & Fields (Paid) All Seasons Mechanical Sales (Paid) Brady Trane (Paid) A big thank you to all our corporate sponsors |

Thanks to all that went to the refrigeration tour -
Hockey Game at the RBC Center in Raleigh. I am
sure that it was good to socialize with some of the
Triangle members at this joint event.
