The 8th Annual Shrimp Boil is here – bring your friends. This is the time in our Chapter where we get to relax and have some fun. I’d like to thank Dan Cross for his help organizing the event once again. The Shrimp Boil will be held at the Winter Park Farmer’s Market on March 25^th from 6pm-9pm. Who knows, you may see some ASHRAE members there that you haven’t seen at our meetings all year. The Shrimp Boil does tend to be the Easter of our chapter, so if you run into someone you haven’t seen in a long time, encourage them to attend our monthly meetings.

Our YEA dodgeball event was an awesome success! We had 48 players and 4 hours of fun. In the end, the team from Xnth took home bragging rights. I can’t wait for next year!!

Until then, we have three special events on the horizon that present a great opportunity for both members and sponsors.

The Spring Golf Outing is on April 9^th at Sanctuary Ridge. A tremendous amount of effort goes into coordinating this event, and I’d like to thank Firouz and his team for their leadership. Please register your foursomes and hole sponsorships today. More information can be found at http://ashrae-cfl.org/events/spring-golf-tournament/.

On May 11^th, the ASPE/ASHRAE product show will be held at the Central Florida fairgrounds. ASPE has planned a “Mexican Fiesta” theme for the show this year so get your sombreros ready. Booths are available. Please visit www.ashrae-cfl.org/events/product-show/ for more information.

Most importantly, I want to remind you that at the end of the ASHRAE year, our chapter is hosting the Chapter’s Regional Conference (CRC) here in Orlando. The CRC will be located at the Rosen Centre on International Drive this August. We want to make sure that we put our best foot forward for our region, and to do this we need your help.  Our biggest challenge in putting this event together is sponsorships. Please consider supporting our CRC – we have some excellent sponsorship opportunities available. Please contact Mike Dillard at mdillard@msifla.com or visit the CRC website at http://crc2010region12.org/

Last year, our student teams that competed in the ASHRAE Student Design Competition, participated in the first annual UCF Energy Symposium sponsored by Progress Energy.  This is a one day event that allows the senior design teams  to show their energy related projects and give a brief presentation to the local community leaders and UCF staff.  Projects last year consisted of everything from making bio-fuel, better controls on traffic lights, solar hot water storage, and the designs from our students for the ASHRAE competition.

This year’s Energy Symposium will be held on April 14 in the Student Union building on UCF’s main campus.  We have three teams competing in the ASHRAE Student Competition so please feel free to stop by and see our students present.  I have had the opportunity to catch a glimpse of our student’s projects and I am very excited about what they are coming up with.  As an added bonus, the building the student teams are working on for this year’s competition is none other than the new Ginsburg Tower at Florida Hospital’s main campus.  Keep in mind that teams from all over the world are working on the same building and, in my opinion, it is nice to have the global community of ASHRAE students focusing on our local community.

We have other items in the works and we will continue to keep you all posted in future issues.  One other item, we have several very bright and talented students in our UCF student chapter.  If any of you are looking for some interns, please let us know; you won’t be disappointed.

There are two options for motors for water cooled chillers, Open Drive and Hermetic Drive. An open drive has an electric motor that is air cooled by the ambient air. A hermetic drive has an electric motor that is hermetically sealed and cooled with refrigerant. With having experience repairing and maintaining both open drive and hermetic drive machines, each arrangement has its advantages and disadvantages.

Open drive water cooled chillers have the possibility to be driven by other means such as steam turbine, gas motor, or gas turbine, etc.  These machines can be converted to alternative refrigerants; the motors do not rely on refrigerant for cooling. Open drive electrical motors can have electrical power diversity, capable of handling high voltages, which will reduce a facilities transformer needs. The electrical motor will have more windings, though, due to higher operating temperatures thus adding motor heat to the space. Repairs can be made to the electrical motor since the motor is accessible. There is a mechanical seal for the compressor shaft that connects to the motor shaft, this mechanical seal will leak in due time. This, as we have all experienced, is in line with the old quote, “More moving parts and more points of connections creates the possibility of more probable failures in time.”

Hermetic drive chillers have electrical motors that are cooled with refrigerant; this allows for reduced motor winding and minimal heat dissipated to the space. The electrical motor heat will be transferred from the refrigerant to the condenser water. Hermetic drive chillers do not have shaft coupling of the motor to the compressor or mechanical seal, which creates a lesser chance for failure. These chillers have placement versatility, i.e. they can be placed outdoors, because the motor is sealed and not cooled by ambient temperatures.

Standard 189.1 was written in conjunction with the U.S. Green Building Council (USGBC) and Illuminating Engineering Society (IES).  Its purpose is to create a standard that provides the minimum requirements for sustainable or green buildings.  This Standard applies to all building types excluding low-rise residential, similar to Standard 90.1.  Although one of the goals of Standard 189.1 is to reduce building energy consumption over Standard 90.1-2007, the Standard addresses other aspects such as site sustainability, water efficiency, occupant comfort, environmental impact, materials and resources.  This Standard is not a rating system but instead written such that it may be adopted by organizations like government, universities or corporations.  It is also hoped to be integrated into green building rating systems and serve as a prerequisite or compliance requirement, such as the ASHRAE Advanced Energy Design Guides (AEDG).  For more information, visit http://www.ashrae.org/greenstandard.
