While other products have been introduced with small amounts of hydrocarbons to help with mineral oil compatibility, Freonâ„¢ MO99 (R-438A) is the best overall all performance match (energy efficiency, capacity, operating pressures, and mass flow rates) to R-22 in air conditioning applications.

R438A (Freonâ„¢/Isceon MO99) is a HFC blend, used as a replacement for R22 in domestic, industrial and commercial air conditioning systems. It is also a retrofit replacement for R22 in low and medium temperature refrigeration systems and DX chiller systems.

R-438A is compatible with mineral oil (MO), alkylbenzene (AB), and polyol ester (POE) lubricants, so in most cases no change of lubricant is required during a retrofit.

To clarify that. It is illegal to mix refrigerants. It is not illegal to skip a leak test on a system holding less than 50 lbs. If I found a bad compressor, on a system using a different refrigerant than data plate, I would not process the warranty.

R438A refrigerant is a suitable replacement for R22.

PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature, to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator and to check the amount of subcooling below the saturated liquid condition at the end of ...
