Can you use new freon in r22 systems?
no. it is not a good idea. new hfc refrigerants require a different type of oil than the R22 units. the new refrigerants typically run at higher pressures than the R22 units.
Can a R410A evaporator be used with a R22 condensor?
No, R410a runs higher pressures.
Can a R410A condensor be used with a R22 evaporator coil?
No, R410a runs higher pressures.
Can you mix r22 freon with R410a in a heat pump?
No , they operate at different pressures and are not compatible.
What are the correct pressures for R410a?
The pressure for an R410a air conditioner system should be 118psi LP and 412psi HP. This is the same pressure as an R22 air conditioner.
Is r12 r22 compatible?
No it's not. R22 is designed for use in home HVAC systems where as R12 is intended for automotive systems. Using R22 in an automobile will cause swelling of seals and hoses, possible compressor failure due to different running pressures.
Is R12 Compatible with R22?
No it's not. R22 is designed for use in home HVAC systems where as R12 is intended for automotive systems. Using R22 in an automobile will cause swelling of seals and hoses, possible compressor failure due to different running pressures.
Can you mix 410 freon with r22 freon?
Absolutely not ... R410 operates at much higher pressures than R22, and mixing would do nothing but contaminate both refrigerants (and possibly mess up your system)
What refrigerant is now used in home central ac units?
Most new equipment is built for and charged with R410a, a refrigerant with much higher pressures than the R22 used for decades, R22 units are still available, dry charged however, you must fill them with R22 onsite. This is how new R22 compatible equipments being sold still.
What are normal R22 operating pressures?
The pressures depend on the temperatures so it is not possible to give "normal" temperatures. The pressures change with the outdoor and indoor temperatures. You need to be EPA certified to attach gauges to the unit to check the pressures.
Why wont R-22 work in a R-12 ac system?
The simple answer is that an R12 system wasn't designed for R22. There are different pressures reached, there are different compressor oils used, and R22 may not even be compatible with a compressor designed for R12. Changing an R12 system to R22 could be done, but it would require extensive conversion, and would still be undesirable - R22 is being phased out, largely because it's a carcinogen and because of the harsh environmental effects.
What should the suction pressure be on a 85 degree day on a R22 split unit?
60psi
