What Freon is compatible with 404A?
What Freon is compatible with 404A?
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. R513A, newer alternative, is also very appropriate in medium back pressure (MBP) applications.
Is R404A A refrigerant?
A Widely Used and Thoroughly Trusted Refrigerant Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges.
What is 404A Freon used for?
R-404A:Refrigerant for packaged air conditioners, commercial air-conditioning and vending machines. R-404A:Refrigerant for showcases, vehicle-mounted refrigerators, and commercial freezers.
What does 404A refrigerant replace?
During the last 10 to 15 years R404A has become one of the most widely used refrigerants. It was introduced in the mid-1990s as a replacement for ozone depleting refrigerants including CFCs (such as R12 and R502) and more recently as a replacement for HCFCs (such as R22).
Can I use 407c instead of 404A?
R407c, in my opinion, is a high temp refrigerant, suited to air conditioning applications. R404a is suited to medium/Low temp applications. The question is, at what point do we choose R407c over R404a, in regards with evaporating temperature etc.
Can I mix R404A with R134a?
Can you mix 404A and 134a? Re: Accidentally mixed R404A with R134a Vacuum is not necessary because R404a consists of R134a. It will never work and your TEV or capillary is not designed for this refrigerant. If you want to destroy your compressor, let it run this way.
What is the difference between R404A and R134a?
R134 is designed for what is called high/medium temp jobs such as chillers R404 is for lower temp work ie freezers. If its for “middle east trucks” then look to see what the supply is for these gases in the middle east and what units you fit to what is recommended by manufacturer.
Can you mix 404A and 134a?
What can you mix with 404A?
R22 is miscible with mineral oil (MO) and alkylbenzyl (AB) oils. R404A is miscible with polyolyester (POE) oil. Since the system being designed for R404A will have POE oil and R22 is significantly less miscible with POE, this can cause the system oil to form slugs and deposits.
Can I replace 404A with 407c?
The changeover from R404A to R407A is said to relatively easy and in many cases, the original oil can be used. R407A, like other gases in the R407 series, is a zeotrope and must be charged in the liquid phase to prevent fractionation.
What kind of refrigerant is Freon 404a made of?
Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. 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.
Are there any cons to using R-404A refrigerant?
The biggest con with R-404A is it’s extremely high Global Warming Potential (GWP). It’s GWP rating is three-thousand nine-hundred and twenty. This number makes it one of the absolute highest GWP refrigerant that is widely used in the world today. In some applications 404A is not the most efficient.
What is the GWP on the refrigerant R-404A?
The GWP on R-744 is one. The GWP on R-404A is nearly four-thousand. That number alone is why the world is pushing to get rid of R-404A as fast we can. Out of all of the HFCs R-404A is one of the absolute highest when it comes to GWP.
What kind of lubricant is used for R404A refrigerant?
This blend has been the standard OEM choice for commercial and industrial low temperature refrigeration. (R507 can also be used in any system specified for R404A.) POE lubricant is required. 24 LB. CYLINDER
