Hello from Cancun! We’re at the Chapter Regional Conference (CRC), and

wish you were all here with us! Annually, our chapter leadership represents

Austin to vote on region and society leadership as well as motions to change

the rules of ASHRAE. It is fun to be a part of voting on new leadership and

organizational changes, plus also possible future society presidents. This is

what makes us a grassroots

organization meaning we put our

members at the top of the organization

and everything else flows down from that. Anyone and

everyone is welcome at CRC, typically there are 2 top

required attendees, but our chapter usually helps

sponsor (along with region & society support) to send

between 5 – 10 additional individuals.

March was an amazing meeting with our highest

chapter attendance in a long time. There was a lot of energy to support the visit from

Society President. We followed this with our annual golf tournament which was perfect

weather. A big thank you to Blair Howell from HTS for hosting the tournament and making

it a success. Total we raised $27,000 for Research Promotions (RP) to date this year and are

looking to get to $47,000 by June 2019. Thank you to Steve Hansen for supporting all our RP

activities. Upcoming is our final RP event BOWLING! Everyone can bowl, come hang out with

our group and support the industry on Monday May 20th, Dart Bowl @ 7pm. Sign up for a team

with Mark Mikulin from EEA! Watch out for the YEA and Student teams as they just had their

joint event April 11th, so they have been practicing.

Besides an amazing topic on Big Data and IOT, we will get to vote for the new the incoming

board of governors (BOG). We would also love to get suggestions on future topics for programs

next year. Typically we plan out most programs in June and July. Next year’s chapter technology

transfer chair (CTTC aka programs) is Stuart Bloomquist from Mech Reps.

Look forward to seeing everyone soon!

Sincerely,

Vanessa J Freidberg

What a turn out! We were just shy of an ASHRAE meeting record attendance. Thank you all for

coming out to support our chapter as well as our Society President, Sheila Hayter, P.E.

Please make sure to show up on time, if not early, as we will start with announcements and officer

nominations right at 5:30 pm. I am pleased to announce we are having yet another Distinguished

Lecturer, Dr. Dru Crawley. Dr. Crawley is a Bentley Fellow and Director, Building Industry Devel-

opment focusing on building performance, BIM, net-zero-energy buildings, sustainability, resili-

ence, and smart cities. He will be updating us on the ever changing world of technology as it re-

lates to the buildings we design and present for expecting clients.

Main Presentation: Big, Smart, and Everything: Data, Technology, Buildings, Cities, and

the IoT By Drury Crawley, Ph. D —Bentley Systems Inc.

There is a transformation under way in the world that will fundamentally change how we interact

with our technology, buildings and cities. Big data allows us to find trends and causes not clear

from our limited data today. Everything is going ‘Smart’ today – from windows, walls and all the

technology in our buildings to communities and cities. With 5G wireless and ubiquitous data sen-

sors soon to be available, every device that collects data can share it – supporting real-time deci-

sion-making for controls, utility grids, buildings, traffic, and transportation. Imagine dozens of

sensors ensuring our comfort in our workplaces while optimizing energy efficiency and sustaina-

bility. This presentation describes the basics of big data, IoT, and Smart everything and its applica-

tions and promise in buildings.

Volume 63, Issue 09

Dear Austin ASHRAE Members:

Reference: Unpaid Society Dues

This is simply a reminder that if you haven’t paid your dues, both locally and for Society, we strongly encourage you to do so as soon as possible.

As summarized in previous months, we are continuously trying to reduce our Chapter’s delinquen-cy counts throughout the year by reminding members to pay their dues once their paid Society year is complete. Remember that once you are on the member delinquency list, you are in a catch-up mode until you make payments (sometimes two close together) at some point during the billing cycle to become current

Please also remember that Society membership is a prerequisite to local membership. Local mem-bership in Austin’s Chapter helps support our local efforts. You can pay your local dues of $40 at the same time you pay your Society dues, or simply bring your dues payment to a monthly meet-ing. This will allow us to keep you informed on all local activities.

If you have any questions, please feel free to contact me at (512) 217-4781 during the day, or via email at Ryan.McLagan@texasairsystems.com. If you find that you have not paid your dues, you can go to the ASHRAE website and pay your dues online at www.ashrae.org. Should you have any questions regarding this effort, do not hesitate to contact ASHRAE headquarters at 1-800-5ASHRAE.

Remember that PAID UP members have the greatest impact on both Society’s and the local Chap-ter’s financial bottom line.

Respectfully Submitted,

Ryan McLagan, Membership Promotion Chair

Research Promotion:

Our annual Golf Tournament was held April 1, 2019. We had a great turnout with 23

teams. And nearly 100 participants. Congratulations to this year’s winners, Daniel

Nuckolls, Stuart Bloomquist, Paul Reyes, and Steve Jalnos, with the Mechanical

Reps Team! Also, we were able to raise over $14,000 towards ASHRAE RP. A spe-

cial thank you to Mr. Blair Howell for organizing this outstanding event.

Our annual Bowling Tournament will be held in May, so please be on the lookout

for the invitation in your inbox. The Bowling Tournament is one of my favorites:

not everyone shoots sporting clays or swings clubs, but EVERYONE can bowl. It’s a

fun event; hope you come out and enjoy!

Refrigeration

We are in continuing the process of planning. We are looking at setting up a brew-ery tour or another interesting way to learn about refrigeration. Since there’s no up-date for refrigeration here’s some facts about refrigeration / HVAC in the US.

Industry History—The Comfort Makers—Part 2

“Though much has been done by ingenious men in the art of distributing heat for household uses;

it must be confessed, that in one or two instances only have they been able to make a permanent

impression or bring their contrivances into that general use as to constitute them "machines of

society." Walter Bernau, Civil Engineer, in his introduction to On the History and Art of Warm-

ing and Ventilating Rooms and Buildings, Vol. I, 1845.

Did you know:

Thomas SAVERY (1650-1715 at right) born in Shilstone, Devon-

shire, England, was an English military engineer by profession and

inventor, and started the industrial use of steam power in 1698. Sav-

ery was drawn in the 1690s to the difficult problem of pumping wa-

ter out of coal mines. Using principles by the French physicist Denis

Papin (1647-1712, the steam digester) and the ideas of Otto von Gue-

ricke (1602-1686), who had experimented with the power of a vacu-

um, Savery developed the first practical steam engine. He used this

engine for "raising water by fire" (1698), and his machine or “fire

pump” became known as The “Miners' Friend” since he intended it

to pump water from mines. His London patent was so detailed he

got it extended (until 1733) which later prevented Thomas Newcom-

en from securing a patent for his own steam engine. Savery's "engine" was a revolutionary method

of pumping water, not only in helping solve the problem of mine drainage, but it made widespread

public water supply practicable.

Savery’s patented machine (at right) consisted of a closed vessel

filled with water into which steam under pressure was intro-

duced, forcing the water to a higher level. When the water was

expelled, a sprinkler condensed the steam, producing a vacuum

capable of drawing up more water through a valve below. To

make the effect as nearly continuous as possible, Savery assem-

bled two containing vessels in the same apparatus. His “boiler”

was in the shape of a cauldron constructed of hammered cop-

per, with a flat top made of lead. Early versions using a soldered

copper boiler would burst easily at low steam pressures. Later

versions with iron boiler could generate steam at 170 kPa (or

24.6 psi).

Industry History—The Comfort Makers—Part 2 (Continued)

Did you know:

The Savery engine had no piston and no moving parts other than hand-operated valves. It was oper-

ated by first raising steam in the boiler, and then admitting the steam into one of the first working

vessels or cylinders, allowing it to blow out through a downpipe into the water that was to be raised.

When the system was hot and therefore full of steam the tap between the boiler and the working

vessel was shut, and if necessary the outside of the vessel was cooled. This made the steam inside it

condense, creating a partial vacuum, and atmospheric pressure pushed water up the downpipe until

the vessel was full. At this point the tap below the vessel was closed, and the tap between it and the

up-pipe opened, and more steam was admitted from the boiler. As the steam pressure built up, it

forced the water from the vessel up the up-pipe to the top of the mine. The engine was used as a low

-lift water pump in a few mines and numerous water works, but it was not a great success since it

was limited in pumping height and prone to boiler explosions.

Savery had some early success due to an energetic advertising campaign which brought him all his

customers. He manufactured several his engines not only for pumping out mines but also for sup-

plying water to large buildings. However, Savery’s engine had many limitations, notably its weak-

ness under high-pressure steam (above 8 to 10 atmospheres).

Just a few years later, Thomas Newcomen independently designed his atmospheric-pressure piston engine from another of the

Frenchman Denis Papin’s ideas. Since Savery held the patent primacy, Newcomen was forced to go into partnership with him and

Savery joined him in the development of his more advanced design of a steam engine. It was marketed under Savery's patent, add-

ing water tanks and pump rods so that deeper water mines could be accessed with the steam power. Newcomen's engine worked

purely by atmospheric pressure, thereby avoiding the dangers of high-pressure steam and used the piston concept invented in

1690 by Papin to produce the first steam engine capable of raising water from deep mines. (Fire Pump, Savery System at right)

Savery's original patent of July 1698 only gave 14 years' protection. However, the next year, 1699, an Act of Parliament was passed

which extended his protection for a further 21 years. This Act became known as the "Fire Engine Act". Savery's patent covered all

engines that raised water by fire, and it thus played an important role in shaping the early development of steam machinery in the

British Isles. The Fire Engine Act did not expire until 1733, four years after the death of Newcomen.
