What is R422D refrigerant?
R422D (Freon™/Isceon MO29) is a HFC blend, originally designed to replace R22 in direct expansion water chillers. It is now used as a retrofit refrigerant for R22 in low and medium temperature refrigeration and air conditioning systems.
Can you top off R22 with 422B?
R422B can be used to COMPLETELY replace R-22 refrigerant in new or existing R-22 residential and commercial air conditioning systems as well as non-flooded evaporator chillers. Cannot be added to R-22 unless fully evacuated and recharged with 422B.
Can Rs 44 be mixed with R22?
A: The standard recommendation is not to mix refrigerants. RS-44 does not form an azeotropic mixture with R22 so that adding RS-44 to R22 in a system will not generate any higher pressures. In strictly technical terms, work has shown that RS-44 may be added to R22 without any adverse effects.
What oil is used with R422D?

Can you mix new 22 with R22?
Can Freon™ MO99™ or Freon™ NU-22B™ be mixed with R-22? No. There is no such thing as a “drop in” replacement for R-22. Mixing refrigerants is not recommended.
Which type of refrigerant is R 422B?
Product Information The hydrocarbon component in R422B helps promote oil return in systems containing mineral oil or alkylbenzene. Although HFC refrigerants won't mix with these oils, the hydrocarbon component thins the mineral oil and keeps it moving around the loop.
Is 422B the same as nu22?
NU-22B (R-422B) is a non-ozone depleting blend, which can be used as a direct refrigerant replacement into existing systems that are designed for R-22, R-407C or R-422D.
Can you charge 422B as vapor?
With the system off, initially charge R-422B in the system to 80 percent of the original R-22 charge as a liquid. Note: Charging a system with R-422B as a vapor will reduce system performance.
Can you mix any other Freon with R22?
With the R22 phase out in 2020 due to its environmental impact, this is a common question for those looking to upgrade their system or change the refrigerant in their system. The answer is no, refrigerants should not be mixed. There are several reasons why mixing refrigerants should not be done.
IS 407C a drop in replacement for R22?
Abstract. The outcome of R407C as a drop in replacement of R22 has been reviewed in this paper. As per Montreal Protocol, R22 is going to be phase out due to its unfavourable impacts related to environment e.g. ozone depletion potential (ODP) and global warming potential (GWP).
What happens if you mix R22 and R410?
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. You can convert your current system to one that runs on R-410A, but the cost will be high.

Can R422D be replaced?
Thanks to its high GWP value, however, it will be replaced with refrigerants with a lower GWP. For plant whose condenser is air cooled, R422D could lead to increase the fan speed or to adopt bigger blowers.
An R-22 Refrigerant Replacement for Direct Expansion Refrigeration
Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.
Features and Benefits
The industry-wide phaseout of R-22 to meet mandates to reduce high ozone-depleting potential (ODP) refrigerants depends on alternative options such as Freon™ MO29.
When will R22 be phased out?
When Will R22 Freon be Phased Out? January 1, 2020, is the last benchmark specifically related to R22 and R142b. There is one more date to remember concerning the EPA’s phase out of HCFC’s. A ban on the remaining production and import of all HCFC’s will go into effect on January 1, 2030.
Why are R22 and R142b being phased out?
As you may know, the Environmental Protection Agency (EPA) has been phasing out hydrochlorofluorocarbon (HCFC) refrigerants like R22 and R142b in order to help protect the ozone layer, which shields the Earth from the sun’s harmful ultraviolet radiation.
Is R410A coolant safe?
Never mind the fact that a new unit that uses R410a as coolant will also be better for the environment , as R410a has an ozone depletion rating of zero. Better yet, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) have given R410a a rating of A1 for safety, yet another consideration.
Is there a ban on R22?
Now, as of January 1, 2020, there’s a ban on the remaining production and import of R22 and R142b, with the servicing of R22 systems limited to recycled and stockpiled quantities of Freon.
Is it illegal to import R22 gas?
For decades R22 (Freon) was the industry standard for A/C refrigerant, but it’s now illegal to manufacture or import R22 (and R142b) gas into the United States. Moreover, the servicing of R22 systems is now limited to the use of recycled or stockpiled quantities of Freon.
Can an R22 be serviced?
An R22 system can only be serviced by an EPA-certified technician —that is, one who has EPA Section 608 certification to service equipment containing R22. The bottom line is that servicing an old R22 unit with existing Freon is likely to cost many hundreds if not thousands of dollars. 2.
What are some alternatives to R-22?
As a matter of fact, there are many different alternatives to R-22 that don’t deplete the ozone layer, including: R-134a, R-507, R-404A, R-407c and R-410A. R-410A is the best alternative option for air conditioning applications, while the best alternative for refrigeration applications are R-404A and R-507.
Is the R-22 still used?
However, R-22 may still be used for the service and repair of existing units. To finalize the phaseout, there will be a complete ban on R-22 as of January 1, 2020, which means the production and import of any R-22 will be entirely illegal. Once that happens, the only way to get R-22 will be through recycled or reclaimed options or by finding a supplier who has stockpiled the product. The 2020 deadline for the final phaseout step may seem like a long way away; however, that’s only a mere five years from now. Qualified technicians with refrigeration training will be needed to handle the phaseout process in the upcoming years.
Is R-22 refrigerant phased out?
R-22, also called HCFC-22, has been a refrigerant mainstay for many years. However, R-22 is now being phased out and non-ozone depleting refrigerant alternatives are being used instead. Ultimately, this will affect the HVAC/R industry in general, and it is definitely relevant ...
Can you use drop in refrigerant on an R-22?
Use a “drop-in” refrigerant. The expression “drop-in” refrigerant is actually a bit misleading. This wording makes it sound like you can add a new alternative coolant to an existing R-22 system; however, this is not correct. Modifications must be made to the existing equipment before alternative coolants can be used.
What is the best refrigerant for R-22?
