View Full Version : Conversion from R22 to R407C, oil issues. kentbf. 26-04-2007, 03:04 AM. We have an A/C system that is designed for R22. It has been converted to operate with R407C.What does the R-22 phase-out mean for me? It depends on how old your cooling system is and if it uses R-22 refrigerant. If your air conditioner or heat pump does, that means it was manufactured in 2009 or before. That also means it's approaching the end of its life expectancy - the average lifespan of an AC unit or heat pump is 15 years.Product Description. A blend of R-32, R-125, and R-134a that has very similar properties to R-22 in air conditioning equipment. R-407C has the closest property match to R-22 in an air conditioning retrofit project compared to other blends on the market. It can also be used in medium temp R-22 refrigeration systems.R-22 vs. R-410A Refrigerant R-22.

Compacted bead type driers can use XH6 or XH9 molecular sieve material such as found in the Emerson Climate Technologies, Inc. EK or EKH series. c.I dont use 407c. I use R422D as drop in, no need to change oil., just need to fix leak, vacuum. then charge unit to 85% of factory charge listed for R22. Pressure will be less than what you get with R22, and better for compressor. Dont try to get the same pressure as R22. it will seem low but thats exactly what it is. And works perfectlyA computational comparison ofR22 and R407C air conditioners with rotary vane compressors has been produced. Cooling capacity of the air conditioner operating on R407C at outdoor temperature of 95 ° F, indoor. temperature of80.6 ° F and relative humidity of 47% is higher than on R22 by factor of 1.038.such as R-407C, were optimized for A/C, while others, such as R-407A, were optimized for refrigeration. While it is possible to use just one refrigerant in all applications, a compromise is being made in the sense that the system will operate but may not be at its best under all required conditions.This video shows that R407c is the closest match to R22 for residential air conditioning.
