Will R12 Gauges Work On R22

A part of the suggested span transcript after expanded is And the evaporator coil was only at say 76. Or maybe 80 degrees. If this saturated temperature right here was higher than both of them. And that means that you don't have r22.

R12 and R22 are two refrigerating agents for air conditioning units. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.

Add 15 to 25 degrees F to the outdoor temperature (say 90+15=105 and 90+ 25=115) and look at the TEMPERATURE information for R-22 on the gauge (green ring of numbers). THE HIGH SIDE NEEDLE SHOULD POINT TO A TEMPERATURE BETWEEN 105 AND 115 (in the green ring of numbers) AND THE PRESSURE IS READ ON THE BLACK RING OF NUMBERS FOR PRESSURE.

Interpretation of the gauges depends on equilibrium (steady state) in the system. IF these factors are normal, the coils are clean, the compressor is OK/normal, the metering device is OK/normal, the components are matched and designed to work together (LOTS OF IFS)…and assuming the refrigerant is R-22:

Are R12 and R22 compatible?

They are two completely different refrigerants,won’t mix at all. But when it blows your system have the decency to tell the service tech what ya did. I have a R12 in basement for long time. I just use it few time for my old car (but the car was gone for ten years) so I think it has a lot left.

Can you use the same gauges for R22 and R410A?

R-22 and R-410A, while intended for the same type of appli- cations, are indeed very different refrigerants. Therefore, they cannot be mixed, and the equipment they are used in will be different.

Can you use R12 gauges for R134A?

Manufacturers Part #: 6025 FJC 6025 R12 to R134a Manifold Gauge Conversion Kit Converts R-12 gauge to R-134A. Contains R-134A 90 degree Quick Couplers and Adapter for R134a Refrigerant Tank.

Do you need different gauges for different refrigerants?

Different Types for Different Work You need two, possibly three, sets of gauges depending on what you are doing. Some techs like to have one set for 410 refrigerant machines and another for R22 machines. However, we have so many different types of refrigerants now it’s not practical to have a set of gauges for each.

What size are R22 fittings?

Newer R410A Ductless Mini Split Systems are usually equipped with a different charging port size to avoid charging of wrong refrigerant into the system (ie R22). This new port size is 5/16″ SAE and some gauge sets carry 1/4″ SAE connectors. Port adapter converts the 5/16″ SAE ports to use with 1/4″ SAE gauge sets.

Can I use R134A in a R22 system?

However, units made after 2010 can use R22 alternatives such as R410A, R134A, R407C, and R407A. These refrigerants cool just as effectively as R22 without the ozone depleting features, and they have an acceptable Global Warming Potential (GWP).

Can you use 410A gauges for R22?

R-22 and R-410A, while intended for the same type of appli- cations, are indeed very different refrigerants. Therefore, they cannot be mixed, and the equipment they are used in will be different.

How do you read R22 AC manifold gauges?

This complete set of air-conditioning gauge set is suitable for mainstream AC R134A and HVAC R410A refrigerants. Including necessary adapters can help you smoothly connect with different refrigerant work equipment.

What size are the R22 hoses?

Different Types for Different Work You need two, possibly three, sets of gauges depending on what you are doing. Some techs like to have one set for 410 refrigerant machines and another for R22 machines. However, we have so many different types of refrigerants now it’s not practical to have a set of gauges for each.

What should my AC gauges read on R-22?

A high-efficiency condensing unit using R-22 can operate at an outdoor temperature of 95F with a discharge pressure of about 250 psi.

What should the high and low side pressures be for R22?

Using R-22 refrigerant and assuming an outside air temperature of 85 °F called for 120 °F inside the compressor (add 35 °F to incoming air temperature) and an output high-side compressor pressure of about 260 psi.

How do you read a refrigerant temperature pressure chart?

This will cause the pressure of the refrigerant to rise. In the example of an R-410A packaged unit with a surrounding air temperature of 75°F, the pressure on both the high and low-pressure side of the system will be 217 PSIG.
