PREXY SEZ

NOVEMBER 2018 Written by: Kenneth Shifflett

Hello fellow ASHRAE Houston Chapter members. We need photos!!! Please take photos with your phone during any ASHRAE event and send them to [email protected]

We are live streaming chapter meetings - if consulting engineers are interested in joining, please email me.

Thank you to our annual sponsors! Greg has done a fantastic job with his Research Promotion fundraising efforts so far. This past October we really got into full swing of Chapter activities with a monthly Chapter meeting, Sporting Clays Tour-nament, and YEA Networking social. November has a full slate as well with ASHRAE Society Scholarship applications due, Chapter lunch meeting on November 14th, and fall golf tournament on November 19th. Please visit the Chapter website for more information and to sign up.

Do you know a MEP consulting engineer that has had a notable career worthy of recognition? If so please contact me so we can consider whom the Chapter will nominate for 2019 Houston E-week Engineer of the Year.

Engineering week is coming up on February 17-23, 2019. This is a worldwide organization whose purpose is to promote engineering career field to students and recognize engineers that have contributed to the profession and accomplished significant achievements. There is a Houston chapter of the society that ASHRAE Houston Chapter will be involved in. The next planning meeting is November 15th and we need our EOY Nominee by then.

This is also a good time to mention my suggestion that you reach out to your local school district to set up a K-12 presen-tation, or maybe just to your child’s class. Doing this during E-week should help you get those opportunities with the school. Terry Connor is our K-12 Chair and has simple and fun demonstration kit that will make the presentation easy.

Looking forward to seeing you at our upcoming events throughout the remainder of the year.

Best Regards,

Ken Shifflett, P.E

2018-19 ASHRAE Houston Chapter President

THIS MONTH’S MEETING SPECIFY BUILDING CONTROLS CORRECTLY; GET A COMPLETE PICTURE OF BUILDING AUTOMATION SYSTEMS

NOVEMBER 14, 2018

Understanding what your controls system

should be capable of can be complex.

The marketplace demands open, stand-

ard communication protocols to deliver

flexible and interoperable control systems

for building owners. Recent innovations in

the industry have made this even more

prevalent. BACnet™ (Building Automation

and Control network) is an ASHRAE®

Standard protocol for building automation

and control networks that prescribes how it

works and how it must be implemented.

The standard is intended to scale from sim-

ple devices to enterprise systems. A vendor

can ultimately decide what functionality

to include in their products. The set of fea-

tures each vendor chooses to implement

will change based on the intended use of the device. It is also important to

remember that no device implements all the features of BACnet. The

functionality needed to implement a temperature sensor is much less than

the functionality needed for a building controller. But, the BACnet standard

was never intended to be a guide for engineers on how to specify automa-

tion systems. The responsibility falls on the specifying engineer to know enough

about the functionality of BACnet, and how the protocol is intended to be

used, so that YOU can correctly specify a system. This article takes an in-depth

look at how different BACnet controls communication technologies including

wired and wireless networks in buildings compare when used for, sensors, building

networks, alarming, data sharing, devise and network management–for a com-

plete picture of the total building automation communication system.

Jim Kohl is an experienced product manager and speaker, is responsible for wireless technologies and light commercial buildings controls. Kohl received his MBA from Metropolitan State University in 2002, where he continued on as an adjunct profes-sor within the Marketing department. Kohl has been awarded a U.S. pa-tent for his work. Kohl has 35 years of experience in filtration and HVAC, including product management, product design, and applications engineering. Previously, he man-aged the aftermarket development group at McQuay International. Pre-vious to McQuay, Kohl designed and managed filtration products at Don-aldson Company for 19 years.

HISTORY ARTICLE WINDOW UNIT A/C HISTORY COMPILATION Written by Bruce Flaniken, PE, LEED AP

The earliest patent for a window type AC patent I'm aware of is one that Gustav Kramer

applied for in 1918 and later assigned to Frigidaire. See attached patent. Actually the

Kramer design was more of a "through the wall" approach.

John Quirk Sherman (yes - Quirk was really his middle name!) was quite the inventor - he

had lots of patents on paper handling machines and was a founder of the Standard

Register Company down the road from me in Dayton Ohio. But he had only one patent

on packaged air conditioners - US 1890888 applied for in 1926 and granted in 1932. As

far as I know the patent was as far as he went. I'm attaching a story about him, but it

doesn't mention anything about AC - I guess his interest in AC was just a "quirk!"

As far as window AC history, apparently the first successful one was put on the market by Philco-York in

the late 1930's, invented mainly by Paul Moore. See attached patent. (One of the original units was do-

nated to ASHRAE after restoration by some of the inventors and Steve Comstock stored it in his office in

NY. Steve will be able to recall the exact scenario, but as I recall it, he had it shipped to Atlanta and dur-

ing the move the wood external cabinet was "lost" and only the refrigeration unit insides got to Atlanta. I

think when ASHRAE moved to their current building there wasn't room for it so Steve sent it to me. In turn

some years ago I donated it to the Refrigeration Research Museum (now an ASME Landmark) in Bright-

on. MI. They also have a complete unit, including the wood casing. (3). about the same time there was

another window AC patented by Matson Terry, formerly of Westinghouse, but I don't know if it ever was

produced. See attached patent (4)

Friedrich factory at 1617 East Commerce Street in San Antonio, Texas. This factory was built by Ed Frie-

drich between 1923 -1925. It is now a national landmark. Friedrich was started by Ed Friedrich. He made

furniture using cattle horns as legs and chair backs - the San Antonio headquarters used to have some of

it on display. They branched into the refrigeration, making grocery type refrigeration cases, Refrigerators

and later to Window A/C.

Henry Galson's work on the first packaged heat pump AC system in the early 1930's and thought this

would be a good paper also, but Henry was deceased and then I found out that one of his co-inventors,

Hans Steinfeld, was still alive and I was able to contact him and he agreed to present a paper also. Both

Faust's and Steinfeld's early work was with console type AC units. There really wasn't any development

work going on for a window type unit until later. GE did get into window units later on, I believe in the

early 1950's but I don't know what role Frank Faust played then. By 1950 window units were seen as a

new cutting edge area for the industry and ASRE sponsored a session at that time - the presentations

were published in Refrigerating Engineering - copies attached.

REFRIGERATION REPORT ENSURING QUALITY PIPING INSTALLATION IN COMMERCIAL REFRIGERATION SYSTEMS

Written by: Matthew Burris

Refrigeration systems piping differ from HVAC systems in two ways. The pipe lengths are large and Excluding VRF systems typically energy is moved via a secondary media. Refrigeration systems like grocery stores or cold storage faculties can have tree to ten thousand feet of pipe. These pipes are flooded with whatever refrigerant that is being used Risk are environmental, injury and death and system failure or excessive service cost. Firms that provide products, design and install need to protect themselves legally, financially and their Reputation.

Below is a listing of some of the risk of improper piping:

Environment – leaks and weld failure releasing Halocarbons into the atmosphere causing air quality problems and environ mental damage.

Mechanical Failures

Rapid release of liquid refrigerant in a public area (Grocery stores) this can cause severe injuries or death.

Release of deadly refrigerants in enclosed areas, (Propane, CO or Ammonia).

System damage caused by welding copper-oxide (slag), excessively plugging filters and changes in mechanical conditions due to piping slag plugging orifices/TXV creating expensive service calls for many years and may reduce the life of the system.

In the pictures below two things should be evident, no black inside of the pipe (proper nitrogen flowing and silver solver well up the joint, means the torch temperature was correct:

What can our members do to help the industry, contractors and the owners who pay the bills avoid the problems cause by bad piping. As designers, suppliers, field engineers and consultants we need to develop specifications that cover materials, proper installation tech-niques and quality control methods for verifying the installation is as intended. Below are just some suggestion to help the entire industry maintain good quality and long system life.

Nitrogen flow rates SCIM (flow enough through the pipe to push out all air and moisture to eliminate oxidation) to eliminate slag inside of pipe.

Cutting out and inspecting fittings for cleanness and complete, sample size or percentages. (20 fittings, 5% of fittings picked by field engineer).

Required filter change before start of warrantee, included would be to place in zip lock bags and turned over to the owner representative for consultant for review.

Specifications are to provide a road map to quality, materials and even acceptable practices. Clearly defined specifications, material assignments and quality procedures provide the owner with a good system, the contractors with a even playing field for biding and the field engineer with the tools he needs to meet the design requirements and investment protection of their customers.

GRASSROOTS GOVERNMENT US: SUPREME COURT REJECTS REVIEW OF COURT OF APPEALS DECISION TO RESTRICT EPA’S BAN ON HFCS

Article Summary: • The US Supreme Court has declined to consider a review of the DC Circuit Court of Appeals decision to

block EPA bans on HFCs.

• The decision leaves in place the 2-to-1 DC Circuit Court of Appeals decision in August 2017 which over-

turned EPA directives to ban high GWP refrigerants like R404A, R134a, R407C and R410A from use in certain

applications.

• The decision was challenged by Chemours, Honeywell and US environmental group the Natural Resources

Defense Council (NRDC).

• When that appeal was rejected at the beginning of 2018, the three companies took the case to the Su-

preme Court .

US: EPA PROPOSES INVALIDATION OF HFC LEAK REPAIR REGULATIONS

Article Summary: • The Environmental Protection Agency (EPA) has announced a proposal to rescind its 2016 ex-

tension regarding leak repair provisions to appliances that use substitute refrigerants such as HFCs.

• The proposal would not affect the requirements for ozone-depleting refrigerants.

• On November 18, 2016, EPA published a rule updating the refrigerant management require-

ments and extending requirements that previously applied only to refrigerants containing an

ozone-depleting substance (ODS) to non-exempt substitute refrigerants, such as HFCs and HFOs.

• The EPA is revisiting the aspects of the 2016 Rule that apply to equipment containing substitute

refrigerants.

• If finalized as proposed, the revised Refrigerant Management rule would rescind the leak repair

and maintenance requirements for substitute refrigerants.

SUSTAINABILITY FUN FACTS ABOUT AIRFLOW SWITCHES ON ELECTRIC DUCT HEATERS AND SINGLE DUCT AIR TERMINAL UNITS WITH ELECTRIC REHEAT (PART 1) WRITTEN BY: GUS FARIS

The airflow proving switch is considered a safety device; its purpose is to lock out electric heat if there is no airflow across the heater. It does NOT measure airflow nor prove a minimum flow. Presence of airflow and pressure is critical because of the temperatures at which electric element wires operate. In normal op-eration, the element wires have a surface temperature of about 600o to 800o F. Under inadequate airflow conditions, this can increase to temperatures above 2,000o F. The airflow switches used on Electric Duct Heaters and Single Duct Air Terminal Units with Electric Re-heat by nearly all electric heater manufacturers are the most sensitive switches available for this type of ap-plication. They operate at a differential pressure of 0.05” w.g. This value has a tolerance and hysteresis of 0.02” w.g. That means that the maximum signal where the switch might activate is between 0.03 and 0.07” w.g. Most of them operate on the low end, but occasionally one will operate closer to the high end. It is important to note that the pressure signal picked up at the probe is a total pressure signal, not a static pressure signal. Static pressure alone in most of these applications is not adequate to operate the switch. For Duct Heaters, there is usually adequate total pressure in the duct system, but the static pressure may be quite low since there are few adjustable devices downstream of the heaters in the duct system. For Duct Heaters mounted on the inlet of the fans in air handlers, the probe may actually measure a negative pressure in the duct. There is a negative side to the air pressure switch that can be attached to the probe in this case. In these negative pressure conditions, turning the probe so that it faces downstream can improve the total signal when attached to the low pressure port on the switch. For single duct Terminal Units, the area in the downstream section of the unit is much larger than that of the round inlet, or the cross sectional open area around the damper blade especially when the airflow is adjusted to minimum values for heating. The probe is usually located in that downstream section; conse-quently, the static pressure will be very low in this area. Since the terminal unit is also set to minimum flow in the heating condition, the velocity pressure will also be low. This is problematic in that neither sufficient pres-sure not volumetric flow may be present to fill the bellows in the airflow switch moving the diaphragm to make the switch. If the pressure and flow are barely adequate, the diaphragm may flutter causing chatter-ing in the contactors and/or relays in the heater control box. This chattering damages the contacts in the chattering relays. When balancing and commissioning these heaters, there are three minimum flows that must be con-sidered: inlet static at the terminal unit, minimum airflow across the heating elements and the minimum pressure and volumetric flow to make the airflow switch.
