What can you use instead of R22?

What can you use instead of R22?

R22 Alternative Options There are several refrigerants that do not cause the depletion of the ozone layer and that can be used as the alternatives for R22. Some of these are R-134a, R-507, R-404A, R-407c, and R- 410A. Refrigerant 507 is the azeotropic mixture comprising 50% of R-125 and 50% of R-134a.

Can I use R290 instead of R22?

Minus40 hydrocarbon refrigerant is R290, a pure refrigerant grade of propane. It can and is already being used in medium and low temperature refrigeration and air conditioning systems as an alternative to HCFC-R22. It is suitable for transport refrigeration and static cool room applications.

Is there a drop in substitute for R22?

In the USA there is no drop-in replacement for R22. The EPA guidelines state that there cannot be a drop-in replacement without modifying the system components.

What kind of freon can you mix with R22?

Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.

Can R22 be used after 2020?

In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. The production (not use) of R-22 is being phased out. You are not required to stop using R-22 air conditioners nor to replace existing equipment.

What is a replacement for R290?

This 8 oz can of R290 (the refrigerant formerly known as 22A) is the equivalent of 1 12 oz can of R22. R290 operates at lower head pressures and offers colder air and improved performance compared to R22. R290 will extend the life of a system because of the lower head pressures.

Which of the following is an approved drop in service replacement for R22?

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.

Can I replace R22 with R134a?

Using R134a in Systems Designed for R22 If you have a home or auto air conditioner designed to work with R22 refrigerant, and the system needs a recharge, a number of issues prevent the direct substitution of R134a. R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger.

Can you use R-22 and R-407C at the same time?

R-407C should be used only in systems that currently use R-22. It should not be mixed with R-22 or any other refrigerant. 5. The capacity of the existing R-22 thermal expansion valve (TEV) will be approximately the same when using R-407C.

Can a R22 compressor be converted to a R407c?

It has the same capacity. And most importantly, it matches the suction and discharge pressures well enough that metering changes aren’t necessary. This video shows how to convert a R22 system to R407c. At least 20% polyolester oil is required in the system to have proper oil return to the compressor.

Which is the best refrigerant to replace R22?

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.

Which is better for the environment R407c or R22?

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). R407C has zero ODP and considerably GWP as compared to R22.
