Unlock AC Efficiency The Definitive AC Pressure Table

The correct low-side AC pressure readings would be for a range of ambient temperatures (80/85/90/95) for the 07 Optima. What should r134a pressures be. The **R134A air conditioner pressure chart** is a precise instrument that maps out the pressure and temperature readings for the ... So if I'm reading the manual correctly, the correct procedure to measure refrigerant pressure is to set AC to max cold, recirc, max fan ... R22 Pressure-Temperature Chart. -49. -45. 1. -17.2. 51. 10.6. 101. 38.3. -48. -44.4. 2. -16.7. 52. 11.1. 102. 38.9. -47. -43.9. 3. -16.1. 53. 11.7. 103. 39.4. - ... Spec is 200-225 PSI on the high and 21-36 on the low. So the high pressure side is to low and the low pressure side is to high. WTF? Any ideas ... It seems that for the outside temperatures in the middle east, pressure gauge reading should go to 50-55. He topped it up till 35 and said it shouldn't be ... Last night I read the FSM, HAC specifically, looking for expected low and high pressure values. Or a pressure chart. I searched the pdf in ... 24 votes, 49 comments. 2013 Nissan Altima, 4 cylinder. First pic is with the engine off, 2nd pic is with the engine and compressor on. Online charts say 85 degree ambient should cause 225 to 250 psi high side pressure. Any reason why a pilot would be different? With the fan on high, it's ~64°. Some things I've read say high side pressure should be roughly double the low side, plus fifty, which would ...
