Lubricant Recommendation: Compatible with mineral and alkylbenzene oil and if oil return becomes a concern, addition of polyolester lubricant in 5% increments could help resolve the issue. Retrofitting to: R-422B for R-22 Air Conditioning page 95. R-422B for R-22 Refrigeration page 95.Vapour pressure. An important point when retrofitting is comparing pressures in the system. The figure below shows the vapour pressure curves of several refrigerants according to their dew point.. The lower pressure values of R513A, R1234yf, R134a and R450A make them feasible for applications from -20°C evaporation and up. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system. The R410a systems also use synthetic oil for lubrication instead of mineral oil as in R22 systems. The synthetic oil is more soluble and more effective for the whole system. Therefore, R410a performs better than R22 and has improved machine performance. R410a Vs. …Argument #1: Pressure. Tube-side materials in R-410A coils need to be thicker due to the higher operating pressures associated with R-410A relative to R-22. We’re not arguing that there’s not a difference in operating pressure between the two. There is – roughly 130 PSI for R-410A evaporators compared to about 70 for R-22.Mini Split Sizing Basics Video https://youtu.be/9L3l4sXRES8How to work on mini splits?

By 2025, high Global Warming Potential (GWP) refrigerants with a GWP of over 750, will be banned together with the systems using that gas. R410A has a GWP > 2,000.The higher the pressure in the cylinder, the less time it takes to force the refrigerant into the system. The heating element should be turned off before the pressure is above the highest pressure on the Dial-a-Charge® shroud of the refrigerant being used. EXAMPLE: Refrigerant R22 is being used - the pressure at no time should exceed 230 psi.We would like to show you a description here but the site won’t allow us.When servicing and repairing HVAC systems containing R22 refrigerant, having the proper PT reference charts is critical.
