What Is R22 Refrigerant

What does the r22 phase out timeline mean for you.

What is r22 refrigerant.

When you change from r22 to an r22 substitute there is more than just changing the refrigerant and a little seal. If a system has r22 in it already you cannot use a replacement refrigerant to simply add to the r22. R22 refrigerant is one of the most commonly used refrigerants. The used refrigerant is extracted from that machine put in a recovery cylinder and then sent to an epa certified reclaimer.

R22 is the short name for the halocarbon compound chclf2 monochlorodifluoromethane which is used as the refrigerant. Reclaimed refrigerant is r 22 refrigerant that was used in another machine at one point in time. Refrigerant r22 is hydroclhorofluorohydrocarbon hcfc. For one r 22 is its own refrigerant whereas the replacement refrigerants are made up of several different kinds of refrigerants designed to mimic operating pressures temperatures of r 22.

R22 refrigerant is also called as freon 22 or simply r 22 freon. Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon hcfc. After r22 becomes illegal to manufacture or import on january 1 2020 it will become much more difficult and expensive to get r22. As a result repairing older r22 systems will become very expensive when the repair requires adding refrigerant to the system.

R22 known as freon 22 is a refrigerant gas mainly used in air conditioning units and refrigerators. You would have to change the oil in the compressor if the oils are incompatible this would require removing the compressor most likely have to change the txvs they control how much refrigerant goes to the indoor outdoor coils and possibly the reversing valve. This colorless gas is better known as hcfc 22 or r 22 or chclf 2 it is commonly used as a propellant and refrigerant these applications are being phased out in developed countries due to the compound s ozone depletion potential odp and high global warming potential gwp although global use of r 22. R22 refrigerant is the old standard for residential air conditioners now being phased out by the u s.

As it is known to cause ozone depletion and global warming hcfc 22 is being substituted. Government has placed restrictions on r22 and has issued the requirement that r22 refrigerant must be eliminated from use in cooling systems by the year 2020. The first is what s known as reclaimed refrigerant. It has one hydrogen atom in its compound and not all the hydrogen atoms from it are replaced.

Lennox offers dry charged units for those who still have r 22 compatible systems.
