Sanyo today announced the development a CO2 Refrigerant Direct Expansion Type Refrigeration System using a natural refrigerant (CO2), the first of its kind in Japan, for use as a refrigeration system for supermarket freezer showcases. The natural refrigerant CO2 has a very low global warming potential compared to an alternative fluorocarbon (about one four-thousandth), and can therefore greatly contribute to the prevention of global warming.
