The recommended suction pressure for R22 varies depending on the specific operating conditions and equipment. However, typical suction pressures for R22 range from 60-70 psi for air conditioning applications. It's important to consult the manufacturer's guidelines or an HVAC professional for specific recommendations.

What should be our suction pressure on a r22 unit on an 83 degree day?
The suction pressure of an R22 unit on an 83-degree day will vary depending on factors such as indoor temperature, coil condition, and humidity levels. A typical range for suction pressure on an R22 unit could be around 60-70 psi on an 83-degree day. It's important to refer to manufacturer specifications and consider other system parameters for an accurate assessment.
What should Suction pressure in a r 22?
The suction pressure in a R22 system should typically range between 60-70 psi when the system is operating under normal conditions. It is important to consult the manufacturer's guidelines and consider other factors such as ambient temperature to ensure the system is functioning properly.
What is the condensing temp for a head psi of 296 psig for an r22 system?
The condensing temperature for an R22 system with a head pressure of 296 psig would typically be around 120-130°F. This is based on the saturation temperature corresponding to a pressure of 296 psig on the R22 pressure-temperature chart.
Why would your air conditioner have normal head pressure and a low suction pressure?
There is no such thing as normal head pressure. It is all based on temperature and calculations. Need to know indoor air temp, outdoor air temp, wet bulb versus dry bulb. Need to know specifics. so when outside ambient temp is 90 and I'm running 255 head with a clean condenser. that isn't normail head pressure? that's pretty normal to me. working with r22 the correct answer would be. If you are sure your head pressure is where it should be, with correct freon type. low suction pressure can be caused by no blower motor, closed or blocked registers, clogged filter or evaporator, lack of airflow, undersized evaperator or oversized AC, restricted metering device(TXV, piston) blocked returns. but he is right you need a lot more info what's your superheat/subcooling? what's your delta T, is you head pressure really wre it should be? what's changed since this started happening. How low issuction pressure what's your evap saturation temp? is coil freezin up? what are your pressures exactly is condenser temp 30 degrees warmer than outside temp. with r22. do you know what you are doing????
What will cause the suction pressure to rise?
An increase in the ambient temperature can cause the suction pressure to rise, as warmer air entering the system raises the pressure. Additionally, any restriction in the refrigerant flow or a dirty filter can also lead to a rise in suction pressure.

How do you determine what suction pressure should be in R22 air conditioning compressors suction line?
The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.
Charging r22 system?

How much the suction pressure when temp reach at -20 c in freon 22 gas?
About 1.6 bar R22 boils at -40c at atmospheric pressure and about 3.8 bar it boils at 0.0 c.
What should the suction pressure be on a 97 suburban?
17-22 Hg
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.
What is the condensing temp for a head psi of 296 psig for an r22 system?
The condensing temperature for an R22 system with a head pressure of 296 psig would typically be around 120-130°F. This is based on the saturation temperature corresponding to a pressure of 296 psig on the R22 pressure-temperature chart.
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
How do you calculate suction pressure for air theoretically?
Air has a pressure, but not a suction pressure. Air pressure is measured with a barometer, you do not calculate it. Suction pressure is a concept which applies to a pump. Suction pressure = static pressure + surface pressure - vapour pressure - friction pressure.
Can R22 be used in a R12 system?
No, R22 is for refrigerators and home AC. It runs at a different pressure and you can't use one for the other.
