A Note from the President:
Our next meeting is our Annual Holiday Party on January 7th. Though there is no technical topic, it still is a great time to socialize and network with other local members. This year we are doing things a little differently and are work-ing with Dorothy Lane Market to put on a wine tasting. It should be a lot of fun with a number of different wines and I encourage everyone to sign up! We are still accepting scholarship applications. The application can be down-loaded off our website, www.daytonashrae.org . We are giving away 3 x $1,000 scholarships this year and will be accepting applications until the end of this month, January 2017. Please get your applications in! If you attended the December meeting at the Engineers’ Club, one of our member’s (Tom Ferdelman) coat went missing. The coat says ASHRAE on it and it was a gift from the Dayton Chapter earlier this year. I believe the coat is blue. The Engineers’ Club has told ASHRAE that there is a coat that was left onsite at the meeting so we believe someone mistakenly has Tom’s coat in lieu of their own. If you attended the meeting, please check to see if you have the wrong coat. If so, please let me know. See you at the Engineers’ Club!

Make YOUR donations by following the directions on Page 6.
To date, Dayton ASHRAE has set a very achievable goal for RP this year. Our goal is $16,920 in Total Research Dol-
lars including funding for Foundations and Scholarship Promotion.
$9,153
Which is 54% of our goal!
2015-2016 saw ASHRAE continue its leadership in developing standards and guidance for the design, operation and maintenance of healthy, ener-gy efficient buildings.
Funds to accomplish this research are received from members and com-panies active in the industry. Once again the Dayton Chapter was among the leaders in Region V , submitting a new high of $16,482. This year’s Goal is $16,920.
The HVAC Industry gives us all our livelihood. ASHRAE’s research and educational programs are what keeps our industry and professions on the leading edge and assures its continued existence. Confident that you will recognize the benefits of this investment, we are asking you to help fund future HVAC&R research and development by donating this year. Thanks so much for your help in advance!

New Duct Sizing Calculator Available ATLANTA – A new duct sizing calculator from ASHRAE and the Air Distribution Institute (ADI) allows HVAC air distribution system designers to more accurately size ducts, especially flex ducts under varying amounts of compression, based on research results.
The Duct Size Calculator is a quick reference tool for approximating duct sizes and equivalent sizes of sheet metal duct vs. flexible duct. The calculator uses information from ASHRAE Re-search Project 1333, HVAC Duct Efficiency Measures, and was developed with funding support from ASHRAE and ADI. ASHRAE Technical Committee 5.2, Duct Design, sponsored the pro-ject.
“While the calculator resembles a wheel type ductulator similar to those used during the days of slide rules, it incorporates three new fields for equivalent duct sizing,” Chris Van Rite, developer of the calculator, said. “These new fields help demonstrate the significant loss of airflow due to improper installation of flexible ducts.”
The calculator includes fields for 4, 15 and 30 percent compression in flexible ducts. Van Rite notes that the calculations used to create these size references are based on straight line com-pression as performed in the laboratory on a flat surface. Field installed flexible ducts with bends, kinks and excessive lengths will have additional resistance, which will result in dimin-ished airflow.
“The use of this tool allows duct designers to account for less than optimum installation and gives a more accurate design to installed performance correlation,” Van Rite said. ASHRAE research has quantified the effects of compression (not stretching) flexible duct, which increases the roughness and therefore the friction loss inside a flexible duct. Airflow testing fol-lows protocols prescribed by ANSI/ASHRAE Standard 120-2008, Method of Testing to Deter-mine Flow Resistance of HVAC Ducts and Fittings. Testing at Lawrence Berkeley National Laboratory and at Texas A&M University along with data analysis by Tennessee Technical University has quantified the adverse effects of compression on airflow. Those correlations agreed closely with the equations published in Chapter 21 of the 2013 ASHRAE Handbook, Fundamentals, so the equations were used to create the new calcu-lator, he said.
The Duct Size Calculator features inch-pound (I-P) units on one side and the International Sys-tem of Units (SI) on the other. The cost of the calculator is $34, ASHRAE members ($40, non-members).
