Customers won't notice but Target and other grocers, including Supervalu, are testing a new type of refrigerant designed to reduce leakage from coolers and freezers, lower greenhouse gas emissions and, eventually, reduce the cost of operations.
Target is testing the refrigerant in 11 of its stores in six states with the help of the federal Environmental Protection Agency, which calls the program "GreenChill."
The technical name of the new refrigerant is 1,1,1,2-tetrafluoroethane, but it goes by the shorthand name of R-134a.
The bottom line is that the gas is a "high temperature" refrigerant less prone to leakage and more energy efficient. It is also used in automobile air conditioners.
