Predrag Hrnjak of the University of Illinois at Urbana-champaign said: ”We found that using potassium formate as a secondary coolant works better than using the usual refrigeration.“ ” Leaking refrigerants from supermarket display cooling systems is a major source of environmental pollution. Experiments conducted by researchers at the University of Illinois at Urban-Champs-Earn recently show that another cooling method can reduce leakage and save money. Predrag Hrniak, a professor of mechanical and industrial engineering, said: "There are about 30,000 large
