Tableau Pression Climatisation Automobile Pdf [portable]

Start the engine, set the AC to "Max Cold," and let it run for 5–10 minutes.

Most vehicles before 2017 use R134a. The following table shows typical pressure ranges based on the (the temperature of the air outside the car). Ambient Temp (°C) Low Pressure (Bar) High Pressure (Bar) 1.5 – 2.0 1.7 – 2.1 1.8 – 2.2 2.0 – 2.5 2.3 – 3.0

exemple : $$P = \fracFA$$

Attach the blue hose to the Low Pressure port and the red hose to the High Pressure port. Compare: Match your gauge readings to the chart above. Safety Warning

For pure refrigerants, pressure and temperature are directly linked when the refrigerant is in a saturated state (liquid + vapor mix). Example for R134a: tableau pression climatisation automobile pdf

Les pressions de fonctionnement normales varient considérablement en fonction de la température extérieure. Voici les valeurs de référence pour un système fonctionnant avec du gaz (climatisation réglée au maximum de froid) : Température Ambiante (°C) Basse Pression (BP) - Bar Haute Pression (HP) - Bar Diagnostic 15°C 1,4 – 2,2 Fonctionnement normal 20°C 1,5 – 2,5 Refroidissement optimal 25°C 1,8 – 2,8 Sortie d'air 4-8°C 30°C 2,0 – 3,0 Pressions été standard 35°C 2,2 – 3,3 HP élevée (normal si chaud)
