About a decade ago, refrigeration equipment started using HFCs (410A and 507) instead of HCFCs for their refrigerant. Air conditioner companies only recently started making that switch. Even refrigeration equipment that was designed for and installed with HCFC-22 is using HFCs that have been specifically created to work with these types of systems. Currently, new refrigerated equipment is being designed to run on “natural” refrigerants. These natural refrigerants include ammonia, hydrocarbons, and carbon dioxide.
Carbon dioxide in refrigeration form is known as R-744. AC Repair Florida does not use it – yet. It is the biggest player, so to speak, in natural refrigeration. Originally, it came into cooling and freezing applications in subcritical configurations. A supermarket, for example, reduces its carbon footprint by using carbon dioxide as the refrigerant. It also gives the store an opportunity to promote environmental awareness to customers.
In order to become free of HFC completely, carbon dioxide systems need to go transcritical. Europe has been doing this for a number of years. Outside of Europe, in 2012, a system free of HFC arrived in an Urban Fare Express store in Vancouver, Canada. Urban Fare Express is one of the first stores in North America to use carbon dioxide in transcritical applications. Urban Fare Express decided to do this because of their commitment they gave to be more environmentally friendly. AC Repair Palm Coast thinks that all companies should be more environmentally friendly.
Ralph Thiel, the director for store planning and construction of Urban Fare Express had a few reasons to make this switch. Not only to show their commitment to sustainability on a daily basis, but also because they have seen synthetic refrigerants being phased out, year after year. He believes that the current HFCs being used will also be phased out. Thiel states that “carbon dioxide transitions us to a natural refrigerant that we can live with in the future.”
I wonder what Publix thinks about this potential refrigeration change.
