R134a Pressure Gauge Readings On the high side, r 134a pressures usually run 2.2 to 2.5 times the ambient temperature entering the condenser. 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. An r 134a refrigerant pressure of 27 psi on your gauge means the refrigerant will produce about 32°f at the evaporator, which is just around the freezing point of water. on the high side, r 134a pressures usually run 2.2 to 2.5 times the ambient temperature entering the condenser. so, if the ambient temperature is 80°f, you’ll see high side.
Reading R134a Pressure Gauge Ambient temperature. the system should be recovered, vacuumed (min 20 minutes) and charged. the gauges readings will depend on the ambient temperature. with the a c turned off on a cold day the pressure will be low, on a hot day the pressure will be high. the table below shows the comparison between temperature and pressure for r134a. Reading a refrigerant gauge is a valuable skill for hvac technicians. understanding the basics of the refrigeration cycle is essential for accurate gauge readings. proper pressure temperature conversion is crucial for interpreting gauge readings. manifold gauges play a significant role in measuring pressure in hvac systems. The automotive hvac gauge readings should be between 35 40 psi on the low side and 145 160 on the high side, assuming an ambient temperature of 70 degrees fahrenheit. aclab note: r134a is an automotive refrigerant. it should read 35 40 psi (low) and 145 160 (high). Step 5. observe the r 134a psi reading on the pressure gauge. if it is less than 24 psi, your system is low and needs additional refrigerant. if your system is within 25 to 44 psi, it has the proper amount of freon. readings of 45 to 64 psi indicate your system is overcharged and you need a mechanic to properly dispose of the excess freon.
