refrigerants - cooling substances, many of which contain CFCs and are harmful to the earth's ozone layer.
renewable energy - energy resources such as windpower or solar energy that can keep producing indefinitely without being depleted.
Chlorofluorocarbons-CFCs - Very stable chemical compound, used in refrigerants, solvent, and (in the past in the U.S. ) aerosols, which release chlorine (important) and fluorine (less important) into the upper atmosphere.
They were first invented by DuPont Corporation in 1928 and have been widely used as refrigerants, as aerosol propellants, as cleaning solvents and in the manufacture of plastic foam.
Chlorofluorocarbons Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming.
Technician: Any person who performs maintenance, service, or repair that could reasonably be expected to release Class I or Class II refrigerants from appliances into the atmosphere.
ozone-depleting gases: Ozone-depleting gases are CFCs, refrigerants, aerosols, solvents, methyl bromide fumigant, and halon.
monoculture: Monoculture is when farmers plant one type of crop only, with no variety.
CFCs are used in many ways, such as aerosol propellants, refrigerants, cleaning solvents and blowing agents.
While conventional chillers have a compressor and use refrigerants to produce cooling, absorption chillers contain an absorber, generator, pump and heat exchanger, and do not use ozone-depleting substances.
Sulfur Dioxide (SO2) - A heavy, smelly gas that can be condensed into a clear liquid; used to make sulfuric acid, bleaching agents, preservatives and refrigerants; a major source of air pollution in industrial areas.
Volatile Organic Compounds (VOCs): compounds that vaporize easily and have low water solubility that are often human-made chemicals used and produced in the manufacture of paints, pharmaceuticals, refrigerants and are components of petroleum ...
