TAC Panels Make Sense of Refrigerants, Operational Visibility and Energy-Reduction Technologies

With our Technology in Action Conference only one week away, we’re eagerly anticipating a series of informative sessions that will allow attendees to interact with the industry’s leading retail refrigeration experts. Building on the success of last year’s format, we’ve once again designed the conference to encourage participation and foster lively debates about the most pressing topics in refrigeration today.

For this year’s theme, we’re adopting the Making Sense webinar platform, selecting topics that are closely related to refrigerants, operation visibility and energy-reduction technologies. And, we’ve once again invited a wide spectrum of experienced end users, expert practitioners and equipment manufacturers to facilitate these discussions and impart their knowledge.

Here’s a brief overview of our interactive sessions:

Discussion One: Optimizing Facility Operational Costs. Explore the landscape of available strategies, tools, services and equipment to help achieve operational cost effectiveness today. Panelists will discuss how these tools can help retailers achieve their facility’s cost reduction goals. Discussion points include:

  • Factors to consider when optimizing a facility
  • Optimizing project development and prioritization
  • Challenges to achieving facility optimization
  • Optimization strategies, tools, equipment and services

Discussion Two: The Case for Case Control. By shifting centralized control of refrigeration operation to individual cases, retailers can significantly reduce energy costs. Learn why case control has not been more widely adopted in the U.S., and explore the implications of case control installation and operation.

  • Installation cost savings and contractor considerations
  • Potential for energy savings
  • Maintenance and commissioning
  • Refrigerant usage

Discussion Three: The Impact of New Air Conditioning Efficiency Standards. Changes to regulations in 2015–2016 will increase the minimum efficiency levels of air conditioning equipment. Learn more about these regulations, review the available technologies, and discuss the implications for both air conditioning equipment and facility design.

  • Changes to the ASHRAE 90.1 standard (and the timing)
  • Importance of full-load and part-load efficiencies
  • Understanding the impacts of voluntary standards (ENERGY STAR™, Consortium for Energy Efficiencies, and others)
  • Equipment design implications (circuit design, variable capacity compressors, expansion valves, etc.)

Discussion Four: Refrigerants — An Asset or Liability? Changes in regulations that mandate refrigerant use are impacting refrigeration architecture in new and existing stores. Learn which refrigerants to use for retrofits and new system designs, in addition to these important discussion points:

  • Best practices in refrigerant management for existing stores
  • A new way of thinking about refrigerants (no longer just an expense item)
  • Establishing a plan to reduce global warming emissions (including R-22 and R404A retrofits)
  • Regulatory and political forces that will impact existing store refrigerant decisions

This event takes place April 14–16 in Point Clear, Ala. Visit www.emersontac.org to learn more. While at the event, we will be tweeting live discussion updates using the hashtag #EmersonTAC. We hope you will be able to join the conversations!

New Refrigeration Technology for walk-in beer keg coolers

The next time you are near Indianapolis, check out Sun King Brewery.  Emerson recently worked with Sun King Brewery (http://sunkingbrewing.com/) to fit new condensing units near the main entrance.  Since there wasn’t room to put the units in the back of the building, they needed quiet, reliable units that look good enough to be seen by visitors – and keep hundreds of barrels of beer fresh.  Read more about this case study

When you go, make sure that you sample their craft beers and take a brewery tour – and look for the new condensing units as you walk in.

Don’t Let Your Retail Business Get a Flat Tire

Does your car tell you when it’s time for an oil change or if tire pressure is low? Armed with this information, you don’t wait for a major auto “failure” before you act—you use condition based maintenance.

It’s the same for your retail business. Wouldn’t you rather do maintenance based on equipment condition before it deteriorates to the point where it may fail if not serviced?

Condition Based Maintenance can answer questions like
•    Which of my refrigeration systems are operating improperly or inefficiently?
•    Which of my refrigeration systems are leaking refrigerant?
•    How can I implement a better preventative maintenance scheme or optimize maintenance dispatches?
•    Where should I focus my maintenance budget?

The best news about Condition Based Maintenance is that many retailers already have most of the equipment needed installed already. Products like Emerson E2 controllers, Copeland Scroll™ compressors with CoreSense Diagnostics™, temperature and pressure sensors are increasingly being installed as standard equipment in many retail operations today.

Connecting our Condition Based Maintenance software and service architecture is the final step many retailers need to take to ensure they are safely driving their business.

For more information about Condition Based Maintenance, view my presentation from Emerson’s Technology in Action Conference.

Fuel Gas Pressure Boosting

There was a lot of talk at the recent Turbo machinery Symposium about fuel gas boosting compressors.  Fuel gas boosting compressors are now a part of most gas turbine systems.  Today’s gas turbine designs operate more efficiently and reliably, but require higher fuel gas pressures than is available from adjacent gas utility pipelines.  To complicate matters, operators must plan for fluctuations in the pipeline pressures.  Although 300 psig is adequate for older industrial gas turbines and could sometimes be reached with pipeline pressures, newer industrial turbines require 600 psig.  Aeroderivative gas turbines can handle load changes more quickly but may require supply gas pressures up to 1000 psig to operate most efficiently.  Because available gas pressures are much lower, fuel gas booster compressors are needed to raise gas supply pressure feeding the gas turbine. FGB compressors must have a large turndown range and the ability to handle gas pressure fluctuations from the pipeline while delivering constant discharge pressure. Fuel gas boosting compressors have recently been deployed in a wide variety of industrial facilities and processes including: peak power plants, oilfield power generation and landfill gas to power projects

What is your experience with fuel gas boosting compressors?  Find out more about fuel gas boosting at http://www.emersonclimate.com/en-us/Market_Solutions/Industrial/Hydrocarbon_Processing/Pages/FuelGasBoosting.aspx

Display Case Energy Standards

If you are involved with refrigerated display cases you might have heard about a new bill before congress called the BURR Act or Better Use of Refrigerator Regulations # H.R. 5710.  This would amend the EPACT 2005, DOE 10 CFR 431 for the portions pertaining to self-contained, medium temperature, service over counter display cases.  This equipment is now classified as a reach-in refrigerator per the DOE 2010 portion of the energy standards.  But because this style of case is all glass and uses a lot of lighting for display of product it has a large heat load as compared to a reach-in, and cannot meet the standards.

If this bill passes the service over counter (SOC) will have its own class and the energy calculation will be based on TDA (total display area) like all the cases covered by DOE 2012 which included SOC remote and ice cream cases. What this means is that the SOC.SC.M cases will now have a chance at meeting the energy standards.

Energy standards have been in place for reach-in refrigerators for many years, including federal minimum efficiency levels which are now in effect.   They were mandated by the Energy Policy Act of 2005 and manufacturers responded.  Since OEMs had already been working on ENERGY STAR models from 2001, it was not a stretch to hit the federal minimum.

The Air Conditioning, Heating & Refrigeration NEWS recently reported on this legislation.
http://www.achrnews.com/articles/120781-legislation-could-establish-unique-standards-for-deli-style-refrigerators

Again, depending on the class of equipment, the calculations defined in the energy standards might be based on refrigerated volume, or could be based on total display area.  This is true for ENERGY STAR and other calculations as well, so be aware of what class of equipment is being considered because allowable energy consumption can vary greatly.
