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.

Solid at normal temperatures and pressures a physical or chemical property?
Physical
What is meant by operating temperature of semiconductor?
The operating temperature of a semiconductor is the temperature at which a semiconductors exhibits the properties of a normal conductor.
How do you determine if charge is correct using R22?
the things that must be considered when charging the system with R22; R404;R134;R507;R406
How does normal boiling points differ from other boiling points of the same liquid?
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.
Is zirconium water soluble?
Zirconium is not soluble in water in normal conditions; a very low solubility is possible at very high temperatures and pressures.
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.
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.
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.
Can you pump down ac system when temperature outside is cold?
Seeing as how, even at operating pressures, the freezing point of R22 refrigerant would be roughly around negative one hundred degrees Fahrenheit, I can't see the outdoor temp ever posing a problem.
What other refrigerant besides R12 can be used on a 1988 Toyota Camry?
No. R12 systems are designed for R12. The lubricating oil for 134a is synthetic and will attack the o-rings in a R12 system. I think the operating pressures are also different.Samething is now happening to residential ACs. R22 is out and 410 is in.They are not compatible.SOL
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.
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.
