What can I replace R404A with?

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.

Is there a drop in refrigerant for 404a?

R448A refrigerant applications, use and replacement refrigerants. R448A is a suitable replacement gas for R404A systems. It can be used in new installations and as a direct replacement gas in existing systems. The GWP drops significantly from 3920 to 1386.

Why is R404A being phased out?

Why is R-404a refrigerant being phased out in commercial refrigeration? While R-404a has eased the transition from R502, R12 and R22, it has been deemed to have a high global warming potential (GWP) of 3,992.

Can R410A replace R404A?

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).

Can I replace R404A with r290?

Compressors manufactured by Embraco labelled r290 are exactly the same as their equivalent r404a compressors. So yes, you can empty an r290 system and replace it with r404.

Can you use R407C in place of R404A?

It has a similar cooling capacity to R404A and improved energy efficiency. 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.

Is r404 banned?

Recovered or reclaimed R404a can be used until the end of 2030, then all replacement R404a will be banned. After 1 Jan 2020, virgin R404A will not be permitted for maintenance and servicing.

Is r448a A drop in for R404A?

R-448A is not a “Drop-in” Replacement R-448A is an HFO-blended refrigerant that utilizes synthetic lubricants. The mass flow differences, as well as the slightly higher discharge temperature in low-temperature applications, should be evaluated.

Is R404A legal?

USA: The US EPA is to ban a host of high GWP refrigerants including R404A, R134a, R407C and R410A in certain new products from as early as January 1, 2021.

Is 404A compatible with 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.

Is R404a the same as R410a?

Particularly, R404a and R407f fluids operate with exactly the same system components (drop-in replacement), while R410a requires the substitution of the sole hermetic compressor (retrofitting operation) without variations in the rated power and efficiency.

What is the difference between R404a and R410a?

The model results also show that in this Hussman R404a display case system, R410a still operates more efficiently with a COP generally 0.16-0.19 greater than that of R404a. As expected, R410a operates at a higher compressor discharge pressure and temperature than R404a.
