In a webinar hosted by the U.S. Environmental Protection Agency on 10 November, Bella Maranion from EPA presented federal sector leadership to reduce HFC emissions through procurement. Special focus was given to the ammonia/CO2 cascade system at a Texas Air Force Base commissary.
“We wanted a future-proof system not subject to changing regulatory rules.”
“We are now bringing that technology to our stores in the United States, with our first CO2 transcritical in Newport, New London. We have a couple of stores in the Seattle area, where we want to put the systems in. And we also want to put a transcritical CO2 system in Edwards Air Force Base in southern California. So we are piloting more than ammonia and CO2 cascade systems; we are looking at all solutions that are out there and we hope to find a solution that will work best for us. This may end up that in climate A we will use one system, and in climate B another system”.
