FRIGORIGENE CHLOROFLUOROCARBONE [1 record]

CONT

In the 1930s, chlorofluorocarbon refrigerants were introduced by T. Midgley, primarily for use in automatic household units; they will produce temperatures well below 0 degree which can be continuously maintained. They are neither combustible nor poisonous. A typical compound is dichlorofluoromethane (CHC12F), but there are many others of similar composition. They are also used in air-conditioning.

OBS

The term "fluorocarbons" is loosely used to include fluorocarbons that contain chlorine; these should properly be called chlorofluorocarbons or fluorocarbon chlorides, since it is these which deplete the ozone layer of the upper atmosphere.
