R134a Pressure Chart Ac Pressure Chart Warnockauto 52ођ The pressure gauges for this refrigerant stays between 22 psi and 57 psi (pounds per square inch). but you have to keep in mind that there are two different sides to this chart. and you have to consider the low as well as the high side. hence, the normal low pressure side for r 134a needs to be less than 90 degrees. The r 134a and r 1234yf pressure charts are for guidance when using a c pro ® recharge kits, refills, and gauges. the charts are intended to help provide an understanding of a vehicle’s air conditioning system pressure, which can be helpful during the diagnostic and recharge processes. be sure to consult the instructions provided with your a.
R134a Pressure Chart Ac Pressure Chart Warnockauto 52ођ The charts start at the low end ( 49°f) and tell you the pressures all the way to the high end (150°f). example: what is the pressure of 134a freon at 85°f? you just chart the chart (found below) and you will see that at 85°f, the pressure of r134a is 95.2 psig (pounds per square inch gauge). measuring the pressure of r134a refrigerant on a. So, if the ambient temperature is 80°f, you’ll see high side pressures running between 176 psi and 200 psi. on an r 134a system. at 200 psi. the refrigerant entering the condenser will be around 130°f. normal ac pressure gauge readings are directly related to the ambient temperature pressure. This table represents a pressure temperature chart for r134a. r 134a is a refrigerant frequently used in automobile air conditioning. additionally, for larger chilled water systems in commercial and industrial chilled water systems. furthermore, r 134a is an hfc or hydrofluorocarbon refrigerant and, as noted, is used for automotive air.
