What Refrigerant Is Compatible With R12?

by | Last updated on January 24, 2024

, , , ,

There are three replacement refrigerant options for R12 systems:

R134a, R401a

What happens if you mix R134a and R12?

R134a systems

work at higher discharge-side pressures than R12 systems

, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

Can I mix R12 and 134a?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. … The advantage of

ester oil

is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.

Can I replace R12 with r600?

With regard to R600a

How do I convert R12 to 134a?

  1. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional. …
  2. Open the engine compartment of your vehicle. …
  3. Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

What is the back pressure of R600a?

Equalising pressure (psig):

58/58

for R600a and 128/128 for R290 for low back pressure. Peak pressure (discharge) (psig): 145 for R600a and 360 for R290 for low back pressure. Stabilised discharge pressure (psig): 113 for R600a and 290 for R290 for low back pressure.

Is R290 same as r600?

For those not familiar with these refrigerants yet, it’s worth noting that R600a or isobutane, is mainly used in household refrigerators and some types of commercial equipment, while

R290, or propane

, is an alternative increasingly more present in commercial equipment.

Can r600 replace R290?


R290 can also be mixed with R600a

as a zeotropic mixture to replace R134a in home refrigerators, and was proved by many researchers [30][31]. … … R290 possesses very good thermophysical properties, such as lower viscosity and higher thermal conductivity, leading to better COP than R22 when properly designed [30].

How do you tell if you have R12 or 134a?

To tell if it has been converted you can look for a sticker on the unit under the hood, which would indicate that it is

R134a

. And you can also look for R134a adapters, which would be located on the charge parts.

How much does it cost to convert R12 to 134a?

It will generally cost you

about $200

to have a mechanic convert an AC system for you. If you want to replace a vehicle’s AC system, it will cost between $1,500 and $4,000 with an average cost of $2,750. If you decide to have a professional work on your car, you will have several options for where to get the work done.

What is the ratio of R12 to R134a?

A charge level

between 75% and 85%

is recommended when converting from R12 to R134a refrigerant.

Which is better R600a vs R134a?

A more environmentally sound refrigerant used by more and more manufacturers is

R600a

(a hydrocarbon called isobutane). Manufacturers are gradually turning over their fridge ranges to incorporate R600a, a more environmentally friendly refrigerant than R134a. R600a also claims better energy efficiency.

Is refrigerant a liquid or gas?

The refrigerant, a chemical compound that changes easily from liquid to

a gas

. When the refrigerant is pushed into the compressor, it is a low pressure gas.

Is R32 refrigerant eco friendly?

Both R32 and

R410a are environmentally friendly

compared to the harmful CFCs used in the 20th century. There’s still room for improvement as both these Refrigerants can lead to global warming. … In terms of the worldwide warming capacity and total chemical residential or commercial properties, R32 wins over R410a.

Can R134a replace R290?


R290

is also an excellent alternative to hydroflurocarbon (HFC) refrigerants R134a (used in refrigerators) and R404a (used in freezers). Using this refrigerant can also reduce overall energy costs by up to 28%.

What is R 744 refrigerant?

Summary. R744 (CO2) is

refrigerant grade CO2

, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. R744 (CO2) is becoming increasingly popular due to its excellent properties.
