help! nahaluan ata ng 134a ang r12 na ercon ko

[fierari]

pinacheck ko ercon ko nung isang araw. at tinanong ko sa ercon shop kung magkano pa recharge ng freon. sabi check muna natin ser. tapos edi tsinek kulang nga. tapos lagay sya. tapos nung bayaran na nakalagay sa resibo 134 a pot* ang tanga. sabi ko ndi ba masisira yan? sabi kasi daw bawal r12 g*go talaga sabay sabi ko nagkamali ka ba ng sulat o 134a nilagay mo sabi nagkamali lang ako ser (ano ba talaga?????) umalis na ko dahil nag mamadali ako sa lakad ko.

ano po ba epekto nito sa ercon ko? malamig pa naman sya. masisira ba kompresor ko? pano ko po ba malalman kung 134 a nga nilagay nya?

Huwag mo na masyado isipin. Wala namang catastrophic na mangyayari. Siguro medyo reduced performance lang dahil hindi talaga kasing lakas magdala ng lamig (at magtanggal ng init) ang R134a compared sa R12. Pero as you said, hindi naman inalis lahat ng R12 sa system mo (nadagdagan lang ng R134a) so may fighting chance pa din.

The only reason na hindi pinaghahalo ang dalawang ito is para hindi ma-contaminate ang equipment sa mga repair facility sa U.S. (where R12 is captured instead of being vented). Dito naman sa atin lahat ng equipment ay contaminated na at ang R12 ay pinakakawalan na lang sa atmosphere basta basta.

ayus balak ko na sana ipa drain. sabi sa ibang talk board kaya daw palitan ng 134a pero papalitan ang mga fitting ng mga may oil seal kasi daw maliliit masyado ang molecules ng 134a. di kaya ito lumusot sa mga fittings ko ? heheh

[OTEP]

The fact na kinailangan mo magpadagdag, malamang may leak ang iyong system. Have your evaporator checked. Lahat ng leaks ko galing sa evaporator.

Hindi mo na kailangan ng fittings na may O-ring kung gagamit ka ng teflon (lahat ata ng tipid style ginamit ko na). Wala bang O-rings ang fittings mo? Yung sakin meron na kasi kahit R12 ang laman.

[fierari]

ang fitting ko eh yung flare type nde yung o ring type. konti lang naman nabawas sakin 2 1/2 yrs na kasi yun malamang nag evaporate lang.

150 lang siningil sakin nung nag charge eheheh. pansin ko lang dati nag fo fog ercon ko yung lumalabas sa vent, ngayon ndi na.

[OTEP]

Wala bang threads iyan na pwede na lang lagyan ng teflon?

[fierari]

meron oki naman sya at mukang walang leak nag alala lang ako sa nabasa ko na maliliit daw yung molecules ng 134 a kumpara sa r 12

R-12 Retrofitting: Are we really doing it because DuPont’s patent for Freon® ran out?
Every week I hear somebody say “this whole R-12 retrofit debacle is happening just because DuPont’s patent on Freon ran out.” Think about that. Assuming it to be true, then for all these years DuPont would have to have been the only company manufacturing and selling R-12 (not!). And then, anticipating that they were going to lose control of the product, they chose to sabotage R-12 by getting the EPA to ban its existence.

Continuing this doomsday scenario, losing their monopoly on the auto refrigerant, they "invented" R-134a and miraculously got it universally accepted by the world as R-12's replacement. And they did this all the while knowing that they would somehow be able continue to monopolize sales of R-134a as well??? Doubtful!

Obviously those concepts are false. Along with DuPont, Atofina Chemicals (formerly Elf Atochem), Ineos Fluor (formerly ICI Klea) and Honeywell (formerly Allied Chemical and Allied-Signal) were all major vendors of R-12, and are today major suppliers of R-134a. The "other three" did not pay royalties to DuPont for their sales of R-12, and will not for R-134a.

i got this from a post by a friend of mine in our board...

----------------------------------
A word of caution about having the notion of a cheap conversion because the critical part of the whole exercise is the cleaning/flushing of the entire system to which some can be easier than others. Probably a "profit" oriented shop will clean/flush your system only once even if you need more than that and say its already fine but here's the thing: your system should be PERFECTLY clean/flushed of the R-12 before you charge it with R-134a becaue the sligthest contamination of both refrigerant in your system can result to acid build-up and the first to go are the aluminum welded portions of your evaporator etc. and you end up spending more in the long run.
--------------------

just so you guys know..

Possible ba yung PERFECTLY FLUSHED? hehehehe.

Alam ko hindi, eh. Kaya nga yung retrofit kit may mga bagong piyesa. Yung hindi mo na makukuha sa flushing. And conversion is not simply replacing the refrigerant.

Pano ba nagkaka-acid build up? May mga contaminated systems na din kasi kami. Wala pa namang problem.
