Replacing CFC Aircons with HFC-134A [Merged]

[johnart]

Was just at LTO mandaluyong this morning to register my car and I saw a leaflet that requires your car aircon to be using R134a. If your car uses R12 you have until 2005 to convert or else you won't be able to register your car. Hay buhay starting with EWD which is good for safety, next emission testing for clean environment and now aircon for the ozone.

Their objective is to be get rid of the ozone depleting freon by 2010.

[pissword]

ano po ang R12 and R134a? yung mga bagong cars ano po ang gamit?

[johnart]

sir sa alam ko po all brand new vehicles sold since 1994 used R134a. Only older vehicles are affected by this.

[artpogi]

I think cars starting at mid-90's have already R134a's as standard, I could be wrong though.

Don't know about early 90's (90-92) kung R134a na sila.

[OTEP]

R-12 ay Freon. Ito yung ginagamit sa mga aircon noong araw.

R134a ay Ozone friendly refridgerant. Lahat ng bagong sasakyan, ito na ang gamit.

Sa U.S., madaming retrofit kits na binebenta. Kaso madami ding panget ang quality.

[sauman]

ganun na ba? may isa pa kaming sasakyan na R12 (92-93 corolla)ang ginagamit na freon. Compressor lang ba ang kailangang palitan dito?

[sturbo]

yung R134a ba yung mas mahal?
will the LTO personnel be able to distinguish by just occular inspection of the compressor?

[johnart]

The way I understood its another testing like emission testing. Panibagong gastos.

R134a is more expensive than R12 because of its environment friendly gases

[OTEP]

I don't know how they will distinguish it. On most cars, only a yellow tag identifies R134a.

Sa U.S., hindi interchangeable ang R12 repair equipment sa R134a equipment (to avoid cross contamination). Iba ang size at thread ng mga fittings.

You will also need a stronger compressor since R134a is not as effecient as R12 in cooling.

[pajerokid]

Iba yung fittings for R134a. Way bigger than those used for Freon.
