<p>A hydrocarbon refrigerant mixture for direct substitution into systems designed for use with refrigerant R-12 is disclosed. The mixture of propane and butane may be advantageously used as a substitute for R-12, thus eliminating the use of ozone depleting R-12 refrigerant. Ideally, the mixture is comprised of 50 % propane and 50 % butane by liquid volume. Alternately, the mixture utilized may contain up to about 75 % of either propane or butane. Use of the refrigerant (12) in an automotive air conditioner (10) having a compressor (11), condenser (18), receiver (20), and an evaporator (22) is disclosed as is use in a residential refrigerator (40).</p> |
