Greetings, and welcome to another exciting ASHRAE Central Florida Chapter year. I can assure you, and you will be exited to learn, that all your Central Florida Officers, Governors and Committee chairs have been hard at work, planning to make the 2005-2006 ASHRAE year an eventful one. Our recent attendance at the Chapters Regional Conference (CRC) in Ft. Lauderdale, will help our Officers and Chairman provide the best service, and most performance for our Chapter Membership

Our speaker for the September 1^st meeting is Mr. Verle A. Williams of Utility service Unlimited. The topic for this months meeting will be “The Virtual Central Energy Plant”. Verle will present information, outlines, savings and operational data that will be helpful to many of you provide energy savings for you clients and building owners. Verle is an ASHRAE Distinguished Lecturer and will be traveling from San Diego to visit with our Chapter. Verle has worked on many Disney and Sea World project locally and as worked with many of our local members in the past. So come on out and support your local ASRAE chapter for our first meeting of the year.

Please register by Monday, August 29th, 2005. Don’t miss out on this great event!

The first meeting of the ASHRAE Central Florida Chapter for 2005/2006 is Thursday, September 1^st at Dubsdread. I needed to get that piece of information out to you in case you don’t read anything else. Please sign up on-line and attend. I hope to see you there!

I am truly excited to serve as President of this vibrant chapter. It will be hard work following in Damon’s footsteps but I’ll do the best I can! I am blown away by the list of people who have volunteered to be our Officers and Committee Chairpersons for this year. Here’s the roster:

I couldn’t be happier than being the coach of this Superbowl caliper team. Now I just get to sit back and let them make me look good!

One of the goals of our team is to increase attendance at our monthly dinner meetings. If you’re not attending the meetings you’re not getting the full benefit of being an ASHRAE member.

We want you to be comfortable at ASHRAE meetings. That’s why I titled this letter “No Jacket Required”. You shouldn’t feel obligated to wear a jacket or tie to our meetings (of course you can wear either if you want to). Feel free to wear business casual clothes. Come a little early and spend some time with the other members and a beverage of your choosing. You never know when a contact will come in handy.

I believe that it is important that the meetings be interesting and not drag on. Here are my commitments to you to achieve that goal:

This year we will offer an advance purchase discount. If you pre-purchase all eight chapter meetings for 2005/2006 you will only pay for seven meetings – a savings of $25.00.

ASHRAE Central Florida Rich In History

As part of our 2005 – 2006 Central Florida ASHRAE we are going to play name that company or person. I will list several facts about the company or person, one in each Dew Point and you will have to submit you answer at the monthly meetings. The person who gets the most correct at the end of the year will get a great prize!!!

Name that Company: The company was started over 50 years ago. The company provides Mechanical, Fire Protection, Plumbing, Electrical, Structural and Telecommunications design services. The Company previously had a branch called MFC. The company has 9 branch offices 8, in Florida 1 in Tennessee.

I will be asking many of you from time to time to provide information on yourself and your company. I think it is important that we share the rich history of Central Florida specifically as it pertains to ASHRAE. I know we have a lot of movers and shakers in or industry in Central Florida that not everyone is aware of. I hope to not only help you learn more about the history of ASHRAE Central Florida but to help preserve current ASHRAE events.

If anyone comes across an interesting, old or unusual HVAC or refrigeration system please contact me. We as a chapter would like to document these systems for our history archives.

I will normally be the person taking pictures at all of the events. I would like to hear your ideas on what you would like to see your history committee provide you with in the 2005 – 2006 year. Please if nothing else come over and shake my hand and introduce your self. It is going to be a very exciting year for Central Florida ASHRAE. Hope to see you at the exception events planned for this year.

Product Directory

This year we are going to do something different with the Product Directory. It will be published on disks and in hard copy. Every Central Florida Chapter member will be mailed or given a disk. Disks will be distributed at the September and October meetings. After that, the remaining disks will be mailed. So if you want you copy early, attend the meetings. Hard copies will be given to participating vendors for exclusive distribution. If you want a hard, please contact your favorite vendor.

Personally I find the Directory to be very helpful. It not only provides phone numbers, address, and names, it also has a cross reference that matches manufacturers to vendors. I am constantly asked, "Who do I need to talked to about such and such product?". And I pull our my well worn Directory and I say "The answer is.......". It is a real time savor.

CTTC - Chapter Technology Transfer Committee

CTTC Committee
The main yearlong goals of the CTTC Committee will be to keep the Chapter informed of all the Regional and Society Awards, and to keep information flowing between the Society, Chapter and local government. This committee is subdivided into Government Activities, Refrigeration and Technical Communications. Brian Mirus will serve as the committee’s overall chairperson. Bob Symmes will serve as the Government Activities co-chair. Bob Egan will serve as the technical communications co-chair. Greg Romanczyk will serve as the refrigeration co-chair.

Government Activities
The CTTC Committee is seeking ASHRAE members to participate as liaisons with local government, school boards, and other business groups/professional societies. As a volunteer, you can help keep the chapter informed on government activities and technical issues related to our industry. If you already attend or would like to attend meetings for any of these groups as an ASHRAE representative, please contact Bob Symmes at bsymmes@grgce.com. With your help, we can keep our fellow local and society members up to date on Central Florida government related issues.
One way to stay up to date on our state government issues is to attend the Florida Government Expo. More information to come on this year’s event. The purpose is to bring government employees, business owners, citizens, etc. together to learn about new directions in our state government. For more information, check out: www.floridagovernmentexpo.com

Refrigeration Activities
The Refrigeration portion of the CTTC Committee is moving to become a separate committee in Region XII. Region XII is advancing this shift of responsibilities this year by individually tracking PAOE points and events specific to refrigeration. Region XII has revived the KRYO award for the top performing refrigeration chairperson for each year. Ron Vallort, ASHRAE President, is a big proponent of refrigeration and is working to increase awareness and knowledge during his tenure. This effort is headed up at the Regional level by our Wade Conlan at wconlan@grgce.com.

Part of the Refrigeration Committee’s push is to add new members from other refrigeration societies dealing with non-comfort cooling, as well as having joint meetings or programs. If anyone attends or knows people in other societies including but not limited to the International Institute of Ammonia Refrigeration at http://wwwiiar.org or Refrigerating Engineers & Technicians at http://www.reta .com, please provide contact information to Greg Romanczyk . We would like to expand our chapter’s membership and learn more about non-comfort cooling refrigeration.

ASHRAE’s Future – Our Dear Students

Where have our dear students gone? These are the very students that are the future of our professional chapter. Over the last year, ASHRAE has expressed serious concern over the diminishing and aging membership. Where will ASHRAE be in 25-50 years? The longevity and success of the society, and our chapter, will someday rest on the shoulders of today’s students. And so it stands to reason that these students need to be introduced and shown value in our society.

Do young student engineers in the HVAC industry understand the benefits of becoming active in a professional society such as ours? It becomes our responsibility to reach out to the students as mentors with hope that some day they will choose to become colleagues who will help bring success to our chapter and our Industry. The students benefit from contact with professionals such as ourselves as it provides them with insight into their future professions as well as professional contacts.

We are unofficially going to declare this year as the “Year of the Student”. We are going to revive the UCF Student Branch. You will see an increase in student attendance at the chapter meetings; in fact one of our chapter meetings is to be held at UCF. I will keep our chapter posted throughout the year on the happenings of the Student Branch.

As your Student Activities Chair 2005-06, I challenge you to support me in our efforts to bring our professional organization to the students. Over the next year, we will be asking for your time, effort, and financial contributions to aid in encouraging student activities. Remember you are investing in our future. Cheers to the “Year of the Student!”

CRC - Chapter Regional Conference

The Central Florida Chapter was the recipient of many awards at the CRC in Ft. Lauderdale. Check out more photos from the Photo Gallery.

Pharmaceutical Refrigeration

There are many temperature sensitive materials in the refrigeration industry that engineers must be aware of when designing. Such materials can be shock sensitive materials, oxidizing materials or any other unstable chemicals highly reactive to temperature. These types of materials involve the need of precise conditioning systems that maintain the thermal conditions necessary for stability. More common materials, however just as critical, relate to the pharmaceutical industries which are vaccines.

Deviations form the recommended temperature range of 36ºF - 45ºF can result in non reversible deterioration of the substance. Tetanus, Hepatitis A and Haemophilius type B lose their potency and must be disregarded if frozen or exposed to thermal conditions above 45ºF. Chemical kinetic wise, the polio vaccine is the most temperature sensitive vaccine.

Typically domestic refrigerators are used to store vaccines however there are specific key design criteria that must be met. The most important element is that of the temperature control system. It should be equipped with tow temperature recording devices allowing temperature and events (door openings and defrost) to be logged and recorded. The control system should return the temperatures as quickly as possible to the desired range. An internal design which exemplifies an even distribution of temperature is also a necessity. Backup refrigeration is another key design factor. Therefore, having two independent refrigeration systems to share the load should one fail would result in proper storage of the vaccine.

What to expect in Standard 62.1 - 2004

Now that the 2004 version of ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality is available, it’s a good idea to know what changes and additions to expect from this widely used standard. Many of the changes and additions occurred as addenda to previous versions of the standard, which was last published in 2001. All totaled the new standard incorporates 17 addenda.

Major changes include a revision of the Ventilation Rate Procedure, changes in wording concerning environmental tobacco smoke (ETS), changes to requirements related to indoor relative humidity and new outdoor air assessment and cleaning requirements.

The Ventilation Rate Procedure has been revised to reflect recent information regarding ventilation impact on indoor air quality and to clarify the adjustments necessary for space air distribution and system efficiency of multi-zone recirculating systems (addendum 62n). Historically, the standard included a cfm/person requirement for a number of different space types, however the revised standard takes into account the fact that air pollutants are generated by building occupant activities and by the building contents. Therefore, the addendum bases ventilation requirements on the number of people a space is expected to hold, as well as the space’s floor area.

Also revised was the minimum ventilation rate table to apply only to no-smoking spaces by deleting smoking lounges from the list of occupancy categories. Also, some rates were lowered based upon their application to no-smoking spaces only. For smoking-permitted spaces, additional (but unspecified) ventilation in excess of the rates listed in the table is required. Another addendum (62g) will further address ETS and is in the works for a future revision of the standard.

Relative Humidity requirements have also been revised in this latest publication of the standard. Previously, Standard 62 recommended that indoor relative humidity be maintained between 30% and 60%. In the new standard, with the inclusion of addendum 62x, there will be no lower limit for humidity. The upper limit will now be 65%. Additionally requirements from addendum 62x are proper building pressurization and a building envelope designed to limit water entry in liquid form and via vapor diffusion and air leakage. Further requirements include insulation of interior surfaces, such as cold water pipes, where condensation may otherwise be expected to occur.

Another addendum that concerns relative humidity is 62t, which contains requirements for drain pan sloping, outlets, sealing, sizing and location to ensure that condensate from cooling coils is captured and drained effectively. This addendum also contains requirements for finned-tube coils to allow for access and cleaning.

The last major modification to the revised standard involves new outdoor air assessment and cleaning requirements. Addenda 62r, 62z and 62af all address outdoor air quality. Addendum 62r requires and assessment of the regional and local air quality, documentation of the results and conclusions of that assessment regardless of the type of ventilation being used (natural or mechanical) or the procedure being used to determine ventilation requirements.

Addendum 62z requires air cleaning for ozone if the second highest daily maximum one-hour average concentration of ozone exceeds 0.160 ppm.

Addendum 62af includes a statement that notes the requirements of the standard will not necessarily guarantee acceptable in door air quality in situations where the outdoor air quality is unacceptable and has not been adequately cleaned.
