What can I replace R404A with?

It is possible to use R455A in refrigeration systems after 2022 with respect to the EU regulation 517/2014. Over time, an extensive literature has developed an analysis of refrigeration systems working with R404A and comparing it with low-GWP refrigerants.

Can R407C replace R404A?

Until now there have been three main replacements for R404A. Two are sister refrigerants to R407C, the initial favourite for use in unitary air conditioning systems using different percentages of the HFC refrigerants R134a, R125 and R32. These are R407A – a blend of 40% R134a, 40% R125 and 20% R32 – with a GWP of 1990.

Is 404A the same as 134a?

The GWP of R404A at 3922 is the highest of all the commonly used refrigerants. R134a is only 1,430 and R407F (Performax LT) is 1850. Hence leakage of 1 kg of R404A is two to three3 times worse in terms of global warming impact than some other HFC refrigerants.

Can r290 replace R404A?

Today, R-290 is used as a low-global warming potential (GWP) replacement for refrigerants R-22, R-404, & R-134a for certain applications.

Can r290 replace R404a?

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.

Can you still buy R404A?

R404A can be used until the end of 2019 but production levels are decreasing rapidly with price and availability becoming a big issue for end users. Recovered or reclaimed R404a can be used until the end of 2030, then all replacement R404a will be banned.

Is R404A illegal?

From 1st January 2020, new regulations state that certain equipment containing R404a gas can no longer be repaired or serviced with fresh gas. If you rely on equipment containing 404a, you may need to upgrade or replace it.

Can you convert r290 to 404A?

Re: swapping r290 for r404a 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.

Is R134a compatible with R404A?

Most Secop R134a compressors can be released for operation with R513A, and most R404A models can be used with R452A. Intensive verification work with existing compressor types and new refrigerant compositions showed that many compressors can also be released for use with these alternative refrigerants.

Can I use r134 in a 404A system?

R404A will have about 50% more capacity and require about 50% more horsepower than R134A at the same conditions. That LT R134A compressor will try to pump whatever you put through it but its motor simply isn’t big enough to handle the power required for the higher pressure refrigerants like R404A.

Can I use R404A in a R134a compressor?

What is the difference between R290 and R404A?

R290 has higher Thermal Conductivity at 0.0676 than R448a (0.0469) R290 has no “glide” for stable temperature and R448a has 7° resulting in unpredictable temperature variations of 7°F. R290 has lower high side compressor pressures which will lead to longer compressor life.

Is R290 the same as propane?

R290 is an extremely pure propane which is used in low temperature refrigeration applications. This propane contains no odourization compared to fuel propane.

Can I mix R404a with R407C?

You’re wondering if you can mix different refrigerants for your air conditioning system. The short-long-only answer is no, never. There are many reasons why it’s impractical, illegal, and not economical for a homeowner to mix refrigerant types.

Can R134A replace R22?

Alternative refrigerants A few popular R22 alternatives are R410A, R134A, R407C, R407A, MO99, and RS-44b. This type of refrigerant is safe for the environment, affordable, and easy to store, use, and transport.

Can I use R134A in a R404A system?

What can we use to replace R-404A?

R-449A is an HFO-based refrigerant blend designed to replace R-404A in stationary refrigeration applications. It combines excellent cooling performance and energy efficiencies with a low-GWP value of 1,397. Also, existing polyolester lubricants used with R-404A can also be successfully used with R-449A.

When will R-404A be phased out?

However, there could be a shortage of recycled refrigerants because, from January 2015, the production of these refrigerants will be phased out step-by-step. As of January 1, 2020, the refrigerants R404A and R507 may no longer be produced. From that date, installations may only be refilled with reclaimed refrigerant R404A and R507.

Can I replace R404A with R134A?

While it has been possible to replace R134a with R1234yf, for R404A the low GWP replacement has not been found. Unlike R404A, these refrigerants a flammable and therefore their use will require new systems specially adopted for the use of flammable refrigerants.

Is R-404A being phased out?

Yes, it is. The Environmental Protection Agency just announced in July of 2015 that R-404A will begin being phased out across the country. Like most phase outs this will occur in phases over the course of many years. The EPA has listed R-404a as unacceptable in newly manufactured machines for the years 2017 and 2019 depending on the application.
