What Is R22 Refrigerant

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

What is r22 refrigerant.

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. The used refrigerant is extracted from that machine put in a recovery cylinder and then sent to an epa certified reclaimer. 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. R22 refrigerant is also called as freon 22 or simply r 22 freon.

If a system has r22 in it already you cannot use a replacement refrigerant to simply add to the r22. What does the r22 phase out timeline mean for you. R22 known as freon 22 is a refrigerant gas mainly used in air conditioning units and refrigerators. The first is what s known as reclaimed refrigerant.

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

It has one hydrogen atom in its compound and not all the hydrogen atoms from it are replaced. R22 refrigerant has been used for years in central air conditioners heat pumps mini splits car ac systems and other refrigeration equipment. Reclaimed refrigerant is r 22 refrigerant that was used in another machine at one point in time. R22 refrigerant is one of the most commonly used refrigerants.

It s the key to absorbing and removing heat from a space. As a result repairing older r22 systems will become very expensive when the repair requires adding refrigerant to the system. Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon hcfc. 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.

After r22 becomes illegal to manufacture or import on january 1 2020 it will become much more difficult and expensive to get r22.
