What's the proper conversion from r12 to 134 of 1996 sentra LEC aircon

[amateur37]

Newbie lang dito , Ask ko lang kung ano proper conversion from r12 to 134 ng 1996 sentra lec. Yung napagtanungan ko na A/C shop sabi flushing lang daw at palit ng oil, drier ok na daw sa 134. Di ba masira ang compressor, ano kaya effect sa lamig, hihina kaya o pareho lang ng lamig ng R12. By the way, original p lahat ng nkakabit sa aircon. advice naman sa A/C shop na mahusay at di tsambahan ang gawa. please kindly post all suggestions, thanks in advance.

as far as from my research. dapat din yung o-ring palitan.

have no idea to the effect to the compressor and effectiveness of the conversion.

natawa lang ako, when my father asked the mechanics about the costs. 25k daw sa convertion. lol

Kung original na R12 yung system, hindi mo na kailang pang inconvert sa R134a, dahil available pa naman dito sa atin sa Pinas ang R12, just unless na may ibang dahilan, e.g. sabi ng LTO kailangan R134a na para marenew mo yung registration ng sasakyan, IMHO other than that hindi mo na kailangan magconvert.

May ilan kasing requirements na kailangan para sa conversion. Bukod doon sa flushing at oil change, as rion suggested, dapat lahat ng o-ring palitan, kailangan palitan din yung service port ng pang R134a, in some extreme cases baka kailangan mo ring palitan ang iyong condenser to achieve the best performance.

sir nakapagkonver na ho tayo ng ganyan..kaya nagpalit ako ng compressor(kaya ko lang pinalitan dahil maingay na,parang merong kumakalansing),drier at expansion valve..sa condencer ay hindi..ang comprsor na para lang sa r12 ay design sa para lang dito..mas mataas kasi ang ipapasok na freon dito tulad ng r134a..in the long runsisibakin din nya ito o wawasakin..ang mangyayari ay back to square one ulet ang trabaho..salmat

how about the freon/oil ratio. same lang po ba? since 134a uses less freon if I am not mistaken.

sa r12 to r134A conversion ,maglagay ka ng 70% r134a .
sa lubrication naman use ESTER synthetic oil , kung ano ang recommended oil capacity yun ang ilagay mo.

this is something else. all the textbooks, manuals and conversion instructions prescribe poly alkyl glycol lubricant (PAG), similar to tf39 aircraft engine oil and not polyol ester (POE)

[bambino]

^^ all cars manufactured w/ r134a systems use PAG oil ,we use PAG oil manufacturing Chrysler vehicles here in Canada and I once stationed at AC department working w/ ac systems.

i use ester to convert r12 to r134a systems its because of the compatibility of the old capella oil and ester oil .

we don't have to flush the whole system as once believed .

i have been using ester oil strictly for conversion only.

if working with original r134a systems i always use PAG oil.

charge with refrigerant R-134a that's it, pareho lang ng standing pressure r12/r134a. cost 1000 pesos....

nothing personal. professionally, you should go to a reputable school to get trained

Yup!! +1000 ako dito. Kaya dito sa Pinas pag-dating sa A/C lalo na sa automotive airconditioning, sandamakmak ang palpak dahil sa mga ganitong klaseng technician kuno.

As of now hindi ko pa sya na ipaconvert sa 134, dinala ko na din sa isang aircon shop lapit dito samin, kailangan daw i flush yung system, then new drier & expansion valve. palitan din ng compressor that's 134 refrigerant compatible. wala sya sinabi re o-ring replacement. Nagtanong din ako sa Banawe, replace drier and flushing lang daw eh pwede na lagyan ng 134 ung system, parang may mali so di na ko nagbalik doon.
by the way before ako mag post dito, bagong flush ung aircon system, pati drier, expansion valve, bago din cooling coil ko kasi nabutas ung dati. Malamig ung aircon pag umaandar sa highway pati sa gabi at pag malamig panahon, pero pag natraffic sa edsa ng mga 11am to 3pm na mainit panahon nawawala ng malaki ung lamig. naglagay na ako ng isang aux fan sa harap, halos ganun din, konti lang improvement. compressor n kaya sira nito, sabi kc ng a/c tech ok daw ung freon at compressor.

ayos! napaka scientific ng explanation.

for optimum performance of your a/c system, use an expansion valve designed for R134a, HBNR o-rings (to prevent leaks), X-7 receiver dryer, PAG 150 ISO lubricant, and maintain an average pressure on the low side at around 27 PSI (32 PSI for R12) when the system has stabilized, at Philippine average ambient temperatures of 80 degrees fahrenheit, your high side pressure should be around 160-190 PSI with a fan blowing into the condenser simulating ram air

nasubukan nyo na po ba gawin ganitong refrigerant mixing sir ? if not sir pls don't recommend such procedure.. deadly and hazardous po kc. mixing R12 and 134a can or may give you a "big bang" sa a/c cooling system.

naka pagtry na po ako (w/ my old Lancer GLXi 91) convert from R12 to 134a. flush the system,replace drier, TXV and did not replace the condenser and compressor. The a/c tech did use oil for R12 for the compressor(dunno the brand of oil) and fill with 134a refrigerant. Same procedure was done last year when i had my a/c cleaned and flushed from another a/c shop. I'm still using OEM compressor and condenser, though I noticed that R12 cooling is somehow better than 134a but quite negligible.

[SIZE=7]Pag ang kotse mo ay 1996 model di advisable gastusan ng malaki sa convertion ng refrigerant lamang, mahina na kasi ang value, baka mas mahal pa ang value ng aircon mo kaysa sa kotse. My nabibili namang r-12. 1997 model pataas r-134a na environmental friendly na lahat.. [/SIZE] bago maubos ang ozone layer wala na sigurong gumagamit ng r-12...

sir the question was... "What is the proper conversion from r12 to134 of 1996 LEC sentra aircon" ... what is the connection of your reply? costing ? etc etc? and from the posting manner pa lang "all caps" .... hmmmm

charge with refrigerant R-134a that's it, pareho lang ng standing pressure r12/r134a. cost 1000 pesos....

also, it seems that you were trying to "mislead" the author of this thread regarding your advise?

[Gundam168]

I just learned from the news today. Cars using R12 refrigerant will be phased out by year 2012 unless it undergoes Non-CFC aircon retrofitting.
