Abstract
An environmentally friendly hydrocarbon refrigerant mixture may be used as a substitute for existing refrigerant in a refrigerant system. The hydrocarbon refrigerant mixture offers greater operating efficiency and effectively replaces chlorofluorocarbon refrigerants. The refrigerant mixture for the refrigeration system includes from about 85% to about 89% by weight propane and from about 11% to about 15% by weight propene.
