  1. E360 Conference 2017 | Trends in Supermarket Refrigeration Architectures

If they haven’t already, the architecture, systems and refrigerants in your supermarket are going to change — significantly. Driving the change? The drumbeat of international, federal and state regulations already arriving. This high-level conference covered a wide range of architectures, equipment and refrigerant options, their complexity, costs and maintenance requirements, and four key operational considerations: energy, economics, the environment and equipment.

 

  1. E360 Forum: Anaheim | Trends in Refrigerant System Architecture & CO2

As ambient temperatures go up, condenser and refrigerator compression efficiency go down. With new refrigerants, including natural refrigerants such as CO2, high temperatures — and the refrigerants’ critical points — become major considerations. In this technical presentation, centering on CO2 refrigerant as an example, we discussed a range of system architecture options and new equipment and components that help CO2 refrigeration tackle high ambient temperatures while maintaining performance.

  1. E360 Webinar 16: Innovation in Refrigeration

This webinar’s short title encompasses the enormous problems facing our industry today, including: dynamic regulations, the need for an unbreakable global cold chain, the call for access to all data, and the needs of a rapidly changing industry. In this webinar, we learned that the process of innovation itself has to evolve to involve every link in the refrigerated equipment value chain. You’ll see these new approaches modeled at The Helix Innovation Center at the University of Dayton in Ohio, where we’re actively pursuing innovations in refrigeration technology through an inclusive, collaborative approach.

  1. E360 Conference 2017 | The Human Equation of Facility Management

This is a story about shortages. Facility managers have a shortage of resources across the board and sometimes have to outsource their facility services. These services face a shortage of technicians — and a big gap in expertise between experienced technicians and the new generation. Under these circumstances, how do you manage costs and ensure efficient responses to facility problems? This conference presented an answer: call on technology to become more intelligent and provide technicians the information they need to do more with less.

  1. E360 Forum: Anaheim | Converting Waste Into Renewable Energy

Ever give a thought to the garbage disposal in your kitchen sink? This presentation showed that it’s no longer a simple appliance, but an environmentally responsible tool that keeps food waste out of landfills, keeps methane out of the air, and creates a new, clean energy source — right from the food scraps going down your sink. InSinkErator, an Emerson company, works to transform water treatment plants into energy powerhouses by creating biosolids to produce energy and fertilizers without waste.

 

Regulatory Landscape in Commercial HVAC Addressed in Latest E360 Webinar

On Aug. 2, we presented the eighteenth installment of our E360 Webinar series. While many of the topics explored here previously dealt with commercial refrigeration, this latest Webinar explored the many impacts of energy efficiency and refrigerant regulations in the commercial HVAC industry. Presented by David Hules, director of commercial marketing for the air conditioning business, the Webinar took a closer look at the two primary forces shaping the regulatory landscape: the Department of Energy’s (DOE) new energy efficiency minimums and the Environmental Protection Agency’s (EPA) phase-down initiative on high global warming potential (GWP) refrigerants.

With HVACR consuming roughly 50 percent or more of all energy in U.S. commercial buildings and homes, it’s no surprise that many of the trends driving the HVAC industry are geared toward providing solutions that deliver the most energy-efficient components, systems and buildings. Green building methodologies, whether LEED or net zero, are taking a whole-building approach to achieve energy efficiencies with particular attention to:

  • Ventilation and air quality
  • Commissioning and monitoring for buildings
  • Coordination of building subsystems

Hules reviewed the current status of energy efficiency code adoption and how it is now determined on a state level using existing versions of the ASHRAE 90.1 standard. The most recent (and most stringent) version of this code, ASHRAE 90.1-2013/2015 IECC, has only been adopted by a handful of states to date. But, based on the DOE’s recent ruling, the IEER (integrated energy efficiency rating) portion of the ASHRAE 90.1-2013 revision of the standard will be mandated nationally on Jan. 1, 2018, on rooftop and/or packaged systems. Hules then explained that this is the first step in a two-phased approach by the DOE, with the second increase in IEER levels coming in 2023.

To meet these increasing efficiency targets, Hules described how new systems will achieve higher part load efficiencies via a number of potential technology levers, including:

  • Multi-speed blower and condenser fans
  • Energy-efficient, modulating scroll compression solutions
  • Larger coil heat exchangers
  • Improved electronic controls

On the refrigerant side of the equation, Hules explained that the EPA’s efforts are part of a global phase-down on HFCs — one that will introduce new low-GWP refrigerants to achieve these phase-downs. The most likely alternatives to replace today’s high-GWP refrigerants are all classified as A2L, or mildly flammable. While these will reduce GWP into the 400–675 range, building code standards must be revised before their use in HVAC applications. To that end, Hules said that feasibility studies and revisions to key standards are currently underway.

OEMs are already preparing for the emergence of A2L alternatives by manufacturing new systems to meet regional requirements or application-dependent criteria. The convergence of the EPA and DOE regulations will present OEMs with the option to approach compliance with each regulation separately, or combine their efforts into a single design cycle. Hules said that while OEMs will ultimately need to produce regulatory-compliant systems, they should also strive to create products that minimize complexity for customers.

Making Sense of Servicing CO2 Transcritical Booster Systems

Amidst increasing regulations to phase-down hydrofluorocarbon-based (HFC) refrigerants, global adoption of CO2 (R744) as a natural alternative is on the rise. But to successfully perform service on a CO2 system, mechanics will need proper training and a deep understanding of the refrigerant’s unique properties.

Seven Keys to Servicing CO2 Systems

Our 13th Making Sense webinar, Seven Keys to Servicing CO2 Systems, offered a basic primer on CO2-based refrigeration and discussed the many implications of servicing a CO2 transcritical booster system. The webinar was presented by Andre Patenaude, director of CO2 business development for Emerson Climate Technologies.

Andre introduced common CO2 system architectures — secondary, hybrid cascade and transcritical booster; the latter is the only system that relies completely on CO2 as its only refrigerant. He explained that CO2’s global adoption has largely been driven by its effectiveness in cooler climates due to its low critical point of 87.8 °F. This is primarily the reason that subcritical systems (where the ambient temperature is typically below 87.8 °F) have been successful to date. It’s also the reason that CO2 transcritical booster system technology (above 87.8 °F) is evolving to enable operation in warmer climates.

In addition to low critical point, Andre explained two other primary differences between CO2– and HFC-based systems:

  • High triple point (where three phases of refrigerant co-exist) — the triple point temperature for CO2 is -69.8 °F, but the pressure is relatively high at 60.4 psig. Technicians need to avoid approaching that point, or the CO2 refrigerant will turn to dry ice in the system. This is why systems need to be charged with vapor CO2 first in order to reach sufficient pressure (145 psig) before switching to its liquid form to complete the charge.
  • High pressure — historically, CO2’s high pressure has been the primary concern for adoption. At supercritical mode, on a hot day above 87.8 °F, the pressures on the roof (condenser) could be as high as 1,400 psig, with temperatures approaching 240 °F. To handle those conditions, stainless steel piping is required. A pressure-reducing valve is also needed to lower the pressures to a point where it’s similar to working with an HFC system (400–500 psig).

Because CO2 transcritical booster systems lose efficiency in warmer climates, several techniques are used to offset the impacts of high ambient air temperatures.

  • Spray nozzles — condenser that mists water to cool air across condenser coils
  • Adiabatic gas cooler — wet pads lining the outside of condenser are used to cool air and keep the system from going into transcritical mode
  • Parallel compression — flash tank feeds an independent compressor with increased suction pressure and smaller motor
  • Subcooling — cools the gas to increase efficiency
  • Ejectors — a means of using high-pressure gas energy to reduce evaporator superheat and increase suction temperature

Andre stressed the importance of having a plan to deal with power outages, including designing systems with generators and standby condensing units to keep CO2 pressures from building up during system shutdown. In fact, retailers should test the effectiveness of their response by performing a trial power outage.

Most importantly, service technicians should be well-trained to understand the intricacies of dealing with CO2-based refrigeration systems.
