ODP Test
A Chlorofluorocarbon (CFC) refrigerant consists of what elements? - ANS-carbon,
fluorine, chlorine
2. What causes a CFC molecule to breakdown when it reaches the atmosphere? -
ANS-UV Light from sun
3. Ozone molecules consist of how many oxygen atoms? - ANS-it contains 3 oxygens
4. The venting of which group of refrigerants is a concern because it has GWP but not
ODP? - ANS-HFC refrigerants don't have ozone depletion potential but have global
warming potential and that's why we still should not blast refrigerant off into the
atmosphere
5. Does the ozone layer work to increase or decrease the amount of ultraviolet radiation
at the earth's surface? - ANS-Works to decrease the ultraviolet rays.
6. Circle the refrigerant that causes the least damage to the ozone layer: R-12, R-22,
R-502, R-134a - ANS-134A
7. Does ozone depletion directly cause an increase in smog? - ANS-No
8. What component in a CFC destroys ozone? - ANS-Chlorine atom. It separates the 03
into 02 and 01 then the chlorine goes to the next 03 and does the process to split them
up again.
9. What are the two environmental issues which refrigerants contribute to? -
ANS-Global warming potential and ozone depletion potential
10.Other than refrigerants, name a class of chemicals which destroy ozone? -
ANS-Halons and Bromine (Blowing agents, fire suppression chemicals, and different
kinds of solvents)
11.After what date of Manufacturing can a vehicle continue to operate its AC system
with a CFC in it? - ANS-Dec 31 1994
12.Can a motor vehicle ever be refilled with a CFC? - ANS-No
