The Dry Heat Exchanger

PRESIDENT'S MESSAGE

The 2012-2013 ASHRAE Tucson Chapter season has begun, and I am excited to be a part of it. We have some great lunch meeting topics set up for this year, a number of Chapter events, and a possible tour coming together for the spring. The annual Golf Tournament will be held in late April, watch for details to follow in the near future. The successful Product Show, held jointly with the local UGBC Chapter, will also return in February 2013, and details are being finalized at this time. To see the full listing of upcoming lunch meeting topics, visit our website at www.ashraetucson.org/calendar. You can also sign up for a Sustaining Membership on the website, which will give you all 9 meeting lunches for the price of 8. If you have any questions, please feel free to contact myself, Tom McGreal at tom.mcgreal@cas-sw.com or Buzz Wright at buzz@kwmech.com.

A VERY big thank you to Robert Kunkel, Quinton Lamoreaux, Buzz Wright, Dave Tyrrell, Eric Buchholz, Dave Palty, Jon Ziegler, Charlie Velasquez, Rebecca Tarantino and Richard Mills for volunteering their time to the Board this year and help organize the 2012-2013 season.

Please note we have made a couple of changes for this season:

  • Meeting location: Feast (3719 E. Speedway)
  • Lunch Prices: $25 for members, $35 for non-members

I believe I can speak for the entire chapter board in saying that we very much look forward seeing everyone at our first meeting. Let’s make this season a great one!

-Tom




SEPTEMBER LUNCH MEETING

  • Topic: Central Chiller Plants Turn Up Gold
  • Speaker: Distinguished Lecturer, Verle Williams
  • Date: Wednesday, September 12
  • Time: 12:00 noon - 1:30pm
  • Location: Feast (3719 E. Speedway)
  • RSVP: www.ashraetucson.org/calendar/september

Energy consumption of chiller plants often goes unchecked. This area has literally been a gold mine of conservation opportunities for 99% of the chiller plants visited. Starting with the pumping system, what pressure differential is there? What is needed in the buildings or air handlers served? What about the devices absorbing the pressure differential? Are they needed or is there another way to accomplish the goal? Is there a balance between the required flow and the pumps installed? Is it a constant speed primary-secondary, a variable primary, or a constant primary-variable secondary pumping system? If it is variable speed pumping, what controls the speed of the pumps?

How about the control system? Are the pumps controlled as one element of an integrated control system, one that reads the needs of the devices served to determine the pump speed and pressure differential? Can the operator easily diagnose the total plant operation with the control system central station? In case of an emergency, can one dial in and look at all systems from a laptop from off-site? Are the flow readouts reliable? Does the control system integrate directly with the chiller control system?

Want to talk about control systems? Come to the meeting and do just that.

ASHRAE Assists College Students With Tuition Through Scholarships

ATLANTA - To help support future generations of engineers, ASHRAE is awarding over $86,000 in scholarship money for the 2012-2013 school year.

"Engineers build our future, so we want to help build up future engineers," William Murphy, Ph.D., P.E., chair of the Scholarship Trustees, said. “Many of the ASHRAE scholarship recipients are already working in the industry part time and some are exploring careers in various areas of HVAC&R. We hope that this added exposure to the industry will lead to employment opportunities for them in the field during and after college."
