Hina lamig..palaki "tik-tuk" compressor

**Gerbo** · September 28th, 2009 09:18 PM

What does this mean?

Kaka-check up pala last week, no leaks s a system daw. Di rin uminit compressor binuhusan ang tubig.

Baffled with this. Please help. Car is an old 93 Corolla GLi.

Ano daw ang low at high side AC pressures. Is there no problem with the compressor clutch. Baka yung compressor belt tensioner ay stucked-up.

gerbo, your "tik tuk" could be caused by one of the two: too low suction side or too high discharge side of the system. there is a compound pressure switch at the recievier dryer of your corolla. any pressure outside the threshold would trigger the "tik tuk" or short cycling

Pa-evaluate ko na rin.

Ano ipapaayos or adjust pagnag-short cycling?

gerbo,
have pressure checks done first:
a. system pressure at rest
b. system pressure at idle speed once airconditioning system is stabilized(i.e. around 15 minutes after start up)
c. system pressure at around 2000 rpm
make sure you get both high and low side pressure garuge readings

mga sir, tanong ko nalang din po yung tungkol sa oto namin about sa "tik tuk" sound na yun, Eto rin po kaya malamang ang pwedeng sira ng aircon ng oto namin, kasi laging kapag nakabukas yung ac habang naka aircon, sobrang lakas ng tik nung sasakyan, pero kapag pinatay ang ac, nawawala naman...naka mazda familia 323 big body po ako,sabi ng erpat ko parang sakit daw ng mazda 323 yun...thanks po

Mas mainam na ipacheck mo yung system pressure para madaling ma diagnose katulad ng sinabi ni jick. Free estimate naman yan sa mga AC shops at dun mo makikita kung ano ang pressure pag nakaoff and on ang ac. Di po sakit yan, katulad ng sinabi ni jick, malaking possibility na nagcucut-off and on ang pressure switch nyan.

Most probably high pressure ang problema. As jick.cejoco is suggesting, kailangan talaga i-check ang system pressure for both suction and discharge. Ang nakikita ko kasing problema sa mga gumagawa dito sa atin, karamihan ay hindi na naglalagay ng gauge sa discharge, they just look at the suction pressure, tapos konting tingin sa sight glass kung meron man, at kung sa palagay nila ay ok na, recharging is finished, kaya hindi na nila nakikita yung other side (discharge) ng system. Kaya kung may mag-crack up na problema dito na magsisimula yung palit dito palit doon. Ito yung maling pamamaraan ng pag-rerepair ng MVAC system.

As the owner, karapatan ninyong malaman kung anong klaseng repair ang ginawa sa A/C sytem ninyo.

May mga indication naman ang maayos na A/C shop.

1. Kailangan malinis ang lugar. Walang maraming kalat. Yung dumi
(contaminants) ang unang kaaway ng A/C system.

2. Technical Know How and Skill ng mga technician, it's true, maraming magaling mag-dismantle, kaya lang marami pa rin sa kanila ang kulang sa basic theory ng airconditioning.

3. Proper Equipment.

At least they have this basic but essential equipment for proper A/C servicing.

a. Manifold Gauge. (Malinis, walang crack ang mga
hose. Both high and low side are working properly. Kailangan pa nga mag-kaiba yung para sa R12 at R134a kahit gumagamit sila ng adaptor).

b. Vacuum Pump. (Maraming Car aircon shop ang wala nito, hindi ko lubos maisip kung bakit wala sila nito, kung walang vacuum pump ang pinuntahan ninyong a/c shop, hanap na lang kayo sa iba na mayroon nito, mas-malaki ang chance ninyo na magagawa ng maayos ang inyong a/c)

c. Electronic Leak Detector. Mas mabilis ito at reliable kaysa soap and bubble method. Kung kailangan itaas ang pressure ng system for leak testing kailangan dry air or Nitrogen (OFN-Oxygen Free Nitrogen) ang gamitin para maiwasan ang moisture contamination.

d. Weighing Scale. Kailangan ito para maiwasan ang undercharging 'o overcharging, mahirap magrely sa sight glass lamang.

e. Temperature Gauge (Thermometer ba ang tawag dito. Para maiwasan yung malamig na sa technician pero mainit pa rin para sa nagpapagawa, at least meron kayong basehan kung ano na talaga ang temperature.)

Hopefully makatulong sana ito para 'dun sa mga nagtatanong kung anong klaseng shop ang puwedeng mag-service ng maayos.
