The 10th edition of ATMOsphere America will be held online, gathering key industry experts, policy makers, end users and contractors for a free, daylong event where attendees can network with peers and learn about the latest developments in natural refrigerant-based solutions. The program will cover market and technological trends, policy and standards updates, the impact of refrigerants, and end users’ perspectives on their experiences with natural refrigerants.
As a champion for the development of natural refrigerant technologies and a gold sponsor for this year’s event, Emerson is pleased to be hosting a virtual booth at this important industry conference. Not only will it give us an opportunity to highlight some of our new natural refrigerant capabilities, but it will also allow us to speak with industry stakeholders about the many developments that impact the use of natural refrigerants. Highlights will include:
CARB compliance — Under the California Air Resources Board’s (CARB) current proposal, the installation of new refrigeration systems containing more than 50 pounds of refrigerant in a new facility must use refrigerants with a GWP rating less than 150. In existing facilities, new installations of systems greater than 50 pounds would be subject to company-wide, fleet GWP reduction targets by 2030 compared to their 2019 baselines. These reductions may be achieved via one of two methods: by reducing the weighted-average GWP (WAGWP) to less than 1,400 GWP, or reducing greenhouse gas potential (GHGp) by 55%. CARB’s proposal could take effect as soon as this January.
R-290 charge limit increases — Recently, the Underwriters Laboratories (UL) approved the second edition of the UL 60335-2-89 standard, which raises the charge limits on commercial self-contained, plug-in displays based on whether they have an open or closed design. For open appliances without doors, the maximum charge limit has been raised to 500g; in closed appliances with doors or drawers, the new charge limit is 300g. These higher charge limits will help original equipment manufacturers (OEMs) to increase system capacities and sizes while capitalizing on R-290’s high efficiency and low GWP. Although additional regulatory approvals and building code updates are needed before these charge increases can fully take effect, this is a critical first step toward wider applicability of R-290.
To support OEMs that develop these self-contained units, Emerson has been producing R-290 compressors and condensing units for many years. Emerson has also been conducting trainings to help contractors and advising OEMs to better understand the new safety considerations for using R-290 to ensure that it can be used safely in these new applications. As manufacturers begin to adopt R-290 systems, they should ensure their systems meet the requirements of UL 60335-2-89 and ASHRAE standard 15. Today, this portfolio is being updated to accommodate larger charges while expanding into new R-290 qualified products.
New CO2 testing facilities — In addition to Emerson’s CO2 transcritical labs in Europe and at The Helix Innovation Center in Dayton, Ohio, we are currently building new testing labs in our Sidney, Ohio, location. These additions will provide more than 110,000 square feet of engineering and lab space and enable the support of system and component-level testing of CO2 products — including Copeland™ semi-hermetic and scroll compression platforms for CO2 transcritical applications — as well as supporting R-290 and other lower-GWP refrigerant alternatives. In addition, these new test labs will be staffed by dedicated engineering and technician personnel and include testing capabilities for compressors, controls, valves, electronics and supporting components.
