R22 refrigerant gas is a hydrochlorofluorocarbon (HCFC) widely used in all sectors of refrigeration and air conditioning.
It has a low ODP value and excellent thermodynamic properties that make this refrigerant ideal for high and medium temperature applications in fixed installations, refrigerated transport and air conditioning.
R-22 refrigerant:
Difluorochloromethane is related to the group of HCFCs. It has a low ozone depletion potential (ODP = 0.05) and a not very high global warming potential GWP = 1700, that is, the ecological characteristics of R-22 are better than those of R-12 or R-502.
It is a clear gas with a faint odor of chloroform, more poisonous than R-12, it is not explosive and does not combust in an oxygen atmosphere.
Compared to R-12, R-22 is less soluble in oil, but easily penetrates through pores and is inert to metals. The refrigeration industry produces high quality oils for R-22. At temperatures higher than 330ºC, R-22 decomposes in the presence of metals producing the same substances as R-12.
It’s fairly soluble in water. The moisture fraction in it should not exceed 0.0025%. The heat transfer coefficient during boiling and condensation is 25% – 30% higher than that of R-12.

R-410A is a near-azeotropic HFC refrigerant gas blend developed as a zero-ozone-depleting replacement for R-22 in new HVAC equipment. Positive evaporation temperatures.
R-410A:
It is the internationally preferred option for new air conditioning equipment, heat pumps, etc. Unlike R-22, R-410A works at much higher pressures and only with POE synthetic oil. The great advantage of R-410A is its high refrigeration capacity that can be 50% higher than R-22. For this reason, smaller components can be used and make machines more compact compared to R-22. Copper fittings, pipes, valves, compressors, etc. must be designed to withstand the increase in pressure of R-410A. Due to its working pressures, R-410A is not suitable for conversion of existing equipment with R-22. For this conversion, R-424A would be recommended as a direct replacement (drop-in) or R-407C as a retrofit.
