* Main application of CFC substitute
|
|
|
|
|
|
134a is a acknowledge substitute of R12, mainly used in refrigerator and car air-condition ae retrigerant.
|
|
141b is used in supplating R11 and R113 as rsfrigerant, washing agent and foaming agent.
|
|
|
142b is used as refrigerant of refrigerating system under the environment of high temperature.
|
|
|
152a is mainly used as mixing working medium and also as gaseous protective agent and medical
|
|
|
aerosoll propellant.
|
|
|
|
|
|
|
R500, R502 are the substitute of R12, which have the virtues of saving electricity and swift refrigeration etc.
|
|
as refrigerant.
|
|
|
|
|
|
|
|
R32, which has a high efficient energy ratio, and can be used as a super-low temperature cryogen,
|
|
can constitute mixing working medium and also directly supplant R22
|
|
|
|
R123 can be used in central air-condition as refrigerant and also can supplant R11 and R113 as a washing
|
|
agent for electronic parts, a foaming agent for urethane plastic.
|
|
|
|
|
R124, R125 can supplant R502 and R22 or compound mixing working medium.
|
|
|
|
R114, R115 can be used as refrigerant , foaming agent, aerosol propellant, isolating gas and etching gas.
