Additionally, HVAC Systems such as chilled water systems in both commercial markets and industrial markets. 0000728639 00000 n Moisture in the system reacts with the refrigerant and oil to form acids and sludge that clog orifice tube screen Moisture in the system that freezes at the orifice tube and restricts refrigerant flow through the orifice. The compressor will shut off once the low pressure triggers the low-pressure switch. Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems. Use the refrigerant drop down for access to over 100 refrigerants. That being said, there are still millions of cars on the road that use R-134a and there will be continue to be for at least another decade or more. 0000672632 00000 n 50-55 psi. Leaves and dust can clog the fins of an evaporator coil, reducing its ability to remove heat from your car. Voltage Tester vs. Multimeter: What's the Difference? On a good working system, the low side should be between 30-45 PSI and the high side can be between 150-250 PSI. Since R134a refrigerant has a lighter volume than R12 refrigerant, the charge needs to be properly adjusted when retrofitting a unit from R12 to R134a. Therefore, if you are a car or appliance technician you will need to have this chart in your kit at all times. Ive seen it multiple times on various refrigerants. The system is overcharged, theres a lack of airflow across the condenser (clogged fins, radiator/condenser fans not working or not working at the proper speed), or you have air and moisture in the system. Static pressure chart for car AC. But to ease things down a bit, it is more important that you focus on the low-pressure gauge and compare it with temperature readings. The condenser fan might not be running due to clogged dirt. Save my name, email, and website in this browser for the next time I comment. The three columns are titled high side pressure columns, low side pressure columns, and temperature columns. In comparison to traditional refrigerants, R134 performs well in both medium and high temperatures, and it also performs well in ambient temperatures because it is non-toxic and non-flammable at these temperatures. First, it picks up enough heat to cause the refrigerant to change state from liquid to gas. R-134A Refrigerant Pressure Temperature Chart, Technical Resource: Refrigeration and Air Conditioning Technology. volume (m^3/kg) enthalpy (kJ/kg) entropy (kJ/kg.K) kPa.
