How To Interpret R 134a Pressure Readings Reference вђ Otosection Because, on an r 134a ac system, 27 psi. on your gauge means the refrigerant will produce about 32°f at the evaporator, as long as the orifice tube expansion valve is operating properly and there’s no air in the system (air in the system can artificially inflate the pressure to 27 psi). on the high side, r 134a pressures usually run 2.2 to 2. 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.
Pressure Readings For Automotive R 134a The r134a pressure chart delineates the relationship between pressure and temperature within an air conditioning system, utilizing r134a refrigerant. this chart is the cornerstone for troubleshooting and optimizing ac systems, ensuring they deliver consistent, cool air without hiccup. but its importance extends beyond mere troubleshooting. A. to read ac gauges for r134a refrigerant, you will need to follow a few basic steps. first, ensure that the ac system is turned off and the pressure in the system is equalized. then, connect the blue hose to the low pressure side and the red hose to the high pressure side. 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. R134a pressure gauge chart. this chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. it can be used for recharging refrigerant, or to diagnose an a c system based on pressure readings from your gauges. ambient temperature (°f).

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. R 134a refrigerant charge quantity for air conditioners & heat pumps: this air conditioning repair article series discusses the the diagnosis and correction of abnormal air conditioner refrigerant line pressures as a means for evaluating the condition of the air conditioner compressor motor, which in turn, is a step in how we evaluate and correct lost or reduced air conditioner cooling capacity.
