What refrigerant is compatible with R22?

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).

What refrigerant can be mixed with R22?

The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined with the remaining R-22 in the system, said Maiorana.

What is the best substitute for R22 refrigerant?

“Forane 427A is one of the most popular R-22 retrofits,” he said. “It has a GWP of 2024 and offers an approximately 3 percent capacity loss compared to R-22. It has the closest performance to R-22 in terms of capacity and efficiency when compared to other retrofits in the market.

Is there a drop in substitute for R22?

Description. RS-44b (R453a) is the newest R22 drop-in replacement refrigerant in the U.S. market. RS-44b has been sold worldwide for the past 5 years, branded as RS-70 outside the US. It is the closest replacement to R22 that operates with very similar discharge pressure, cooling capacity and flow rate as R22.

Can you use 407c in place of R22?

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants.

R22 Refrigerant Replacement - 410A Refrigerant

Can I put R410A in a R22 system?

The answer is yes and no. You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force.

Can I use R32 instead of R22?

Relatively, R32 has very low GWP compared to R22, and therefore leading R32 to be a potential substitute for R22.

Can you use 404a in place of R22?

R404A and R507A as substitutes for R22 and R502. These blends are chlorine free substitutes (ODP = 0) for R22 as well as for R502 in medium and low temperature ranges.

Can you top off R22 with MO99?

Can R-22 be topped off with Freon™ MO99? No. Freon™ MO99 should not be used to top off R-22 systems. Mixing refrigerants is not recommended.

Can I add R290 to R22?

Because R290 has similar saturated pressure-temperature characteristics and volumetric refrigerating capacity as R22, is miscible with the oils typically used in R22 compressors, is relatively cheap and is reported to yield favourable efficiency, it is often deemed as a desirable option to use in existing R22 systems.

What is the difference between R22 to 404A?

The exhaust pressure of R404A refrigerant is about 1.2 times that of R22, and the mass flow rate is about 1.5 times that of R22. The exhaust flow rate increases and the resistance increases. Generally speaking, the heat exchange capacity of the condenser is increased by 20% to 30% than R22.

What is the difference between R22 and R407C?

The R407C compressor shows exergy efficiency higher than the R22 one due to its better isoentropic efficiency. R22 condenser exergy efficiency is higher than the efficiency ofR407C. Exergy efficiency of the R22 expansion valve is much higher than exergy efficiency of the R407C expansion valve.

What is 404A Freon used for?

Freon™ 404A (R-404A) Refrigerant

It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. Its properties make it ideal for use in display cases, refrigerated vehicles, ice makers, and other applications.

Can I replace R22 with R410A?

No. You can't do that. It probably wouldn't work. Even though you put a compressor in there that's R410A, the rest of condenser probably isn't tested and rated for operating at R410A pressures because R410A has to operate at a higher pressure.

Is 410A better than R22?

Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it's more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.

Is R407C still legal?

A number of common refrigerants, including R134a, R410A and R407C, will be banned from use in new chillers in the USA from January 1, 2024.

What refrigerant can you mix with 404A?

Like R407A, R407F is fully compatible with the POE lubricants used in an R404A system and, in many cases, the original oil can be used. R407F has a lower mass flow than R404A, so some recommend checking existing piping to ensure compatibility.

What refrigerant will replace R404A?

What are the best replacements for R404A? For cold rooms and other small to medium commercial refrigeration applications, R448A and R449A and R452A or R134a are excellent alternatives to R404A, with from 50 to 65% reduction in GWP.

Can I replace R404A with R410A?

Bortolini et al. (2015) concluded that the most suitable refrigerant to replace R404A in medium evaporating temperature conditions is R410A and in freezing cooling loads, R407F (Figure 7).

Is R290 the same as R22?

Coefficient of performance with R290 is slightly lower than that of with R22. However, higher COP can be expected by especially designed system pertaining to the properties of R290.

Can you use R12 in a R22 system?

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 I use propane in an R22 system?

However, propane's operating pressures and temperatures are well suited for use in air conditioning equipment, including chillers. Propane's performance characteristics are similar to those of the now-outlawed R22 – which was phased out because of its high ozone depletion potential.

How do you convert R-22 to MO99?

Is MO99 the same as 438A?

Among those products is Freon™ MO99™ (R-438A), a retrofit refrigerant for R-22 that does not require an oil change. Freon™ MO99™ works with: Residential and commercial air conditioning systems (rooftop and indoor packages units, direct expansion chillers, split systems)
