R134-a refrigerant brand

[warrior]

Does refrigerant brand matter(KLEA,Kalton,Doowon) in the effectiveness in the air conditioning system? Is one brand better than the other?

I think its like buying fuel. The better one is usually the most expensive one. In terms of freon. The quality lies in the mixture of refrigerant and oil and the quality of type of oil and of course its purity.

A bad quality freon would have a very small percentage of air and other gases along the refrigerant.

I thought a good quality refrigerant would have a very small percentage of impurities.

I thought a good quality refrigerant would have a very small percentage of impurities.

I think its just a grammar misconception..

Good Quality = no impurities such as air and other different gases. It should only have Refrigerant freon+Oil.
Bad Quality = Has small percentage of impurities.
Really Bad Qaulity = Has large amount of impurities including rust hence aircon will never get really cold and lines will get clogged up and mess with other components such as the condenser (Holes and lines of condenser are very small and dirt can clog this easily).

Sometimes people just use old empty freon tanks which contains already rust inside! This rust will go into your system. Then you begin to wonder.. Bakit ayaw lumamig aircon ko? Lolz

To prevent this there is a freon filter used for charging.. Then again most or no airconshops consider this.

Kaya best way to fill and recharge your airconditioning unit is DIY. Get your equipments such as own vacuum pump,gauge,tank and filter.
This price will not exceed 6k php. And in my opinion it's worth it. Since you can recharge your own Aircon (if its 134A as well),Ref,other cars and your own car at home. So its really worth having one. And of course a good trusted place to buy clean contaminant free freon refrigerant.

The scam lies is that you cannot see what's really inside their tank or your tank. Even the hoses are colored.

^^ bro may idea ka ba kung magkano ang per kilo ng R134A jan sa PINAS? thanks

^^ bro may idea ka ba kung magkano ang per kilo ng R134A jan sa PINAS? thanks

I think it is around Php350.00 per kilo.

thanks for the quick reply bro , I APPRECIATE.

Freon is a brand name owned by Dupont

No. types of refrigerants does. Ammonia is the best because of high boiling point.

Efficiency to cool is the method of measurement. That now depends on the design of the system and the machines.

plus ten ako sir

wala sa brand ng refrigerant ang mahalaga pulido gumawa ang technician mo, at wag gumamit ng recycled na refrigerant most of the shop used recycled para makatipid lumaki at ang kita

I Hope hindi to OT; Well I guess it is , sorry pro wala akong mahanap na related thread. I hope nobidy minds. Inputs very much appreciated.

-How doe R134 differ from R12, which is better?
-Can both be interchange in the same system?
-R12 po ba is phased out na'? I mean old tech?; Kase sabi nong mech' palit daw ng R134 wala na daw gumagamit ng R12. totoo ba to?
- If kailangang e convert ang system to R134; ano po ba ang major parts sa system na papalitans from R12?, magkano kaya estimate sa paggagastusan?

Accdg to my supplier's account manager from China, you can use R12 on R134a systems and vice-versa. Mas mabilis daw lumamig ang R12 pero mas environment friendly ang 134a.

I don't know if that is accurate though.

horsepower,
R12 is NOT interchangeable with R134a. the reason why
r12 was discontinued was the tearing of the ozone layer that protects us earthlings from the harmful ultraviolet rays of the sun. it is replaced by the earth friendly R134a that does not contain chlorine responsible for tearing holes in the ozone layer. R12 was near perfect refrigerant that for almost each psi of R12 is proportionate to 1 degree fahrenheit of temperature.

turbodingo,
if you retrofit from R12 to R134a, you will need to change the compressor oil from polyol ester to polyalkyl glycol, change the o-rings from nitrile to HBNR o-rings, change or install service fittings for R134a, change the receiver/dryer of accumulator/dryer and in some cases change the expansion valve. the system needs to be drained and flushed of old lubricant and replaced with pag oil.

Thank for clearing that out sir jick, That's what I thought it's not interchangeble. I 've noted the thing you mentioned, so the compressor doesn't need to be change anymore right?, With the mentioned modification how much do you think it will cost?

[Horsepower]

Thanks Jick. I also thought it sounded strange but since she's a pretty chinese girl, yeah, I gave her the benefit of the doubt. hehehe.

horsepower,
good call. i'd probably do the same thing
