Term
|
Definition
| Chemical elements such as chlorine and fluorine that replace hydrogen atoms to create halogenated hydrocarbons. Other halogens include iodine and bromine |
|
|
Term
|
Definition
| Molecules that are comprised of only hydrogen and carbon atoms; methane and ethane are examples of hydrocarbons |

Term
|
Definition
| 1987 legislation resulting from a meeting of 23 countries that jump started to program that slowed the production of ozone depleting substances |
|
|
Term
|
Definition
| Blended refrigerants that behave similar to azeotropes, but that operate with temperature glides and are subject to fractionation |
|
|
Term
| Ozone Depleting Potential (ODP) |
|
Definition
| The index used to measure a chemical substance's effect on ozone depletion as compared to the effects of CFC-11; the ODP ranges from 0 to 1 |

Term
|
Definition
| The atomospheric shell around the Earth that is between 0 and 7 miles above the surface of the Earth |
|
|
Term
|
Definition
| Blended refrigerants that behave similar to azeotropes, but operate with temperature glides and are subject to fractionation; these refrigerants experience larger temperature glides than near azeotropic refrigerant blends |
