President's Report

March 2018

President's Report

From the President’s Desk……  


Oscar Cobb Jr., PE

As I contemplate plans for the upcoming remainder of this ASHRAE season, I also contemplate the changes that we have seen in this month’s weather patterns.  Although not so unusual in Michigan, others are experiencing quite a variety of change.  With temperature swings from highs to lows, devastating storms and natural disasters, I think about how critical it is for engineers today to design more sustainably. I believe it is an inevitable truth that what we do here on Earth will make a difference in the length of time that this Earth and its natural resources remain in usable condition.

While at the ASHRAE conference in Chicago this year I visited the Museum of Science and Technology.  While I enjoyed every part of the museum, the most captivating to me was the videography work called Extreme Ice by James Balog.  This display showcased a video and photo time lapse of the rapid melting of the polar caps in Antarctica and other parts of the world over the past 10 years. This is worth a bit of consideration by each one of us as we examine our role in engineering and our desire to impact the change that's happening.  It will take the efforts of the young and older engineers, architects, contractors and others working together to come up with new sustainable solutions that enhance our environment but also preserve the planet that we are currently living on.  So, I encourage you, let's get involved. Let's make a difference, take advantage of the education opportunities and the input opportunities that ASHRAE offers as an organization.

Along these lines I encourage you to attend this month's meeting on refrigerants and see where the industry may be headed.  This has been a topic in our industry for quite some time now since the Montreal Protocol in 1987 and then Kyoto Protocol 5 years later.  We have come to the point where we must fully adopt the agreed upon changes.  Trying to manage ozone depletion potential (ODP), global warming potential (GWP) alongside system installation pressures, new efficiency standards and life safety is a big task.  So please come out and hear what's on horizon.

Hopefully you have also signed up to take advantage of another great learning opportunity being offered by Detroit SMACNA this week on March 15th.  The session will be on MI Code compliance & Medical Marijuana Facility Guidelines. 

Thank you to all who came out to the Young Engineers in ASHRAE golfing event.  To those who had already left when I arrived, I’m sorry I missed you, but all the reports say you had a good time!  We hope you will continue to participate in these events.  In fact, our committee chair will soon be publicizing the next event which promises both educational highlights as well as some fun.  Please be on the lookout for that and sign up.

It's been a pleasure again to share with you this month.  We hope to see you in person soon. 

Your Detroit ASHRAE President,

Oscar Cobb

Title: Refrigerants - Where are we headed in North America?


The refrigerant issue is back!  Those of you who have been in the industry for some time may remember the transition away from CFCs and HCFCs.  With new climate considerations many of the refrigerants we are using today are being called into question for the future.  This presentation will cover the of the basics surrounding the refrigerant issue: Alternatives, safety, performance and next steps.


William E. (Bill) Dietrich 
Product General Manager for Chillers at Daikin Applied Americas. This includes all air cooled 
and water cooled Centrifugal and Positive Displacement machines. Prior to joining Daikin 
Applied, Bill was the Vice President of Global Engineering for Baltimore Aircoil Company.  In 
addition, Bill spent many years at both McQuay and York International prior to joining BAC.  
With over 30 years’ experience in the industry, Bill has held numerous Engineering and 
Marketing Applications positions addressing commercial/industrial HVAC equipment (chillers, 
AHU, rooftops, cooling towers and evaporative condensers) and systems using these 

He has a deep chiller background and was involved in the transition from CFCs and HCFCs to 
HFCs, and is actively involved in the work and discussions regarding the new low GWP 

Bill has a BSME from University of Minnesota Institute of Technology and an MBA from the 
University of Minnesota Carlson School Of Management.  He is active in industry organizations 
such as AHRI and ASHRAE.  Past chair of TC 8.2, Centrifugal Machines, and the ASHRAE CEC, and

Chapter Technology Transfer


May 10, 2018

Judging Criteria (Total 100 points):

Energy Efficiency (15 points)

Indoor Air Quality (IAQ) and Thermal Comfort (15 Points) Innovation (15 Points)

Operation and Maintenance (15 Points)

Cost Effectiveness (15 Points) Environmental Impact (15 Points)

Quality of Presentation (5 Points)

Judges' Prerogative (5 Points)

Special Note on Judging Criteria:

Even if not all the scoring topics apply to the project, an entry will be considered in the competition. Yes. Judges are instructed to use a "plug" score for a project that is innovative and good in most respects but does not lend itself to all criteria. For example, a wood-drying operation may not have an impact on indoor air quality. However, points will be deducted from the scoring where the topic applies to the project but was ignored.

Tips From The Fan Man

March 2018

Proper Inlet and Outlet Connections – A Different Slant

When airfoil backward inclined wheels first came out in the ‘60s, almost everyone thought they were the answer to all the problems encountered with forward curved wheels. As we know, that was not the case, although they certainly had many advantages, such as a steeper performance curve and a non-overloading HP characteristic (if they were selected properly).

While backward inclined fans are more forgiving than forward curved fans relative to static pressure changes, because of the steeply rising performance curve, the usual precautions relative to proper inlet and outlet conditions must still be considered.  This is as true of plenum fans as it is for housed fans.  The idea that, because a fan is unhoused, you can put discharge connections just about anywhere is simply not true.

Although the discharge connection(s) from a plenum fan are somewhat more tolerant than from a housed fan, you still have to use good duct design parameters to not create turbulence, uneven flow or back-pressure problems.
