What Is R22 Refrigerant

What does the r22 phase out timeline mean for you.

What is r22 refrigerant.

As it is known to cause ozone depletion and global warming hcfc 22 is being substituted. As a result repairing older r22 systems will become very expensive when the repair requires adding refrigerant to the system. The used refrigerant is extracted from that machine put in a recovery cylinder and then sent to an epa certified reclaimer. R22 refrigerant has been used for years in central air conditioners heat pumps mini splits car ac systems and other refrigeration equipment.

The first is what s known as reclaimed refrigerant. If a system has r22 in it already you cannot use a replacement refrigerant to simply add to the r22. R22 refrigerant sometimes known as r22 freon or hcfc 22 freon is an environmental danger because it contributes to the depletion of the ozone layer. 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.

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. Lennox offers dry charged units for those who still have r 22 compatible systems. Reclaimed refrigerant is r 22 refrigerant that was used in another machine at one point in time. R22 refrigerant is also called as freon 22 or simply r 22 freon.

Refrigerant r22 is hydroclhorofluorohydrocarbon hcfc. R22 is the short name for the halocarbon compound chclf2 monochlorodifluoromethane which is used as the refrigerant. 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. Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon hcfc.

R22 known as freon 22 is a refrigerant gas mainly used in air conditioning units and refrigerators. It has one hydrogen atom in its compound and not all the hydrogen atoms from it are replaced. R22 refrigerant is one of the most commonly used refrigerants. It s the key to absorbing and removing heat from a space.

When you change from r22 to an r22 substitute there is more than just changing the refrigerant and a little seal.
