What is the best drop in refrigerant for R22?

R-407c
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. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

Can you mix RS44B with R22?

The Environmental Protection Agency (EPA) in the United States does not permit the mixing of different refrigerants. However, it is known from experience in Europe that the unintended mixing of RS-44b with R22 will not generate higher pressure readings, loss of efficiency or component damage.

Is EF 22a legal?

No. EPA’s SNAP Rule 21 listed as unacceptable (prohibited) refrigerant products sold as 22a and all refrigerants identified as flammability Class 3 in ANSI/ASHRAE Standard 34–2013 for retrofitting residential and light commercial unitary split AC and heat pumps.

Is RS44B a good replacement for R22?

RS44B is compatible both with the traditional mineral & alkylbenzene oils, and also the polyol ester lubricants so that there is no need to change the existing lubricant in the system when retrofitting to R22. Accordingly, RS44B is an excellent choice to replace R22 in the majority of applications where R22 is found.

What refrigerant can I mix with R22?

R-407C
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.

Is rs44b flammable?

Fire Hazard: RS – 44 is not flammable at atmospheric pressure and in air at temperatures up to 100 °C (212 °F). RS – 44 Can become combustible with high concentrations of air at elevated pressure and/or temperature and in the presence of an ignition source.

Is 422b a drop in for R22?

Refrigerants: National™: HFC: R422B A retrofit blend that is designed to match R22 in air conditioning applications. There is a slight reduction in capacity which would result in slightly longer run times.

What is r407c refrigerant used for?

R-407C is a non-azeotropic mixed refrigerant composed of the three ingredients R-32, R-125, and R-134a, and was developed as a substitute refrigerant for R-22, used in applications such as air conditioning equipment and chiller equipment for medium temperature ranges.

What is Red Tek 22a?

RED TEK® 22a, a hydrocarbon-based refrigerant, is designed as a direct replacement and retrofit refrigerant option for replacing R22 substitutes in commercial air conditioning and refrigeration systems.

Can I mix R22 with R290?

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.

When did they phase out R-22 refrigerant?

As everyone knows R-22 was phased out in 2010, production was scaled back in 2015, and it will be completely phased out in 2020. With these phase outs occurring over the past five years the price of R-22 Refrigerant has sky rocketed to right at about three hundred dollars for a thirty pound cylinder.

What to do if your air conditioner has r-22a in it?

If you believe R-22a or another hydrocarbon refrigerant was introduced into your air conditioner, EPA recommends that you contact your local fire department for guidance. New refrigerant recovery equipment that has been designed and approved for use with flammable refrigerants is now available. You may also report a violation of EPA’s regulations.

Is it safe to use r-22a heat pump?

Why is r-22a considered a significant new alternative?

Because R-22a is flammable, it can burn or explode if there is enough product concentrated in one space and the refrigerant comes in contact with an ignition source. 3. R-22 and EPA’s Significant New Alternatives Policy (SNAP) Program
