Hydrocarbon Refrigerants
Air, ammonia, carbon dioxide, hydrocarbons and water are the only
refrigerants with no ozone depletion, negligible global warming and
low environmental impacts in production. The hydrocarbons, ethane,
propane, isobutane, normal butane, isopentane and normal pentane, occur
naturally in petroleum. They and their mixtures are commonly used as
refrigerants. Their refrigerant numbers are 170, 290, 600a, 600, 601a
and 601 respectively. Hydrocarbon refrigerants are popular and safe
with simple precautions. Over 20 million user years in car air
conditioners between 1991 and 2000 gave no personal injury or property
damage from the flammability of hydrocarbon refrigerants.
