What is the normal pressure for a car air conditioning system?
1 Answers
The normal high pressure for a car air conditioning system should be 1.3-1.7MPa (13-17kg/cm2 or 190-250Lbf/in2); the normal low pressure should be between 0.15-0.25MPa (1.5-2.5kg/cm2 or 20-35Lbf/in2). Details are as follows: 1. Function of the air conditioning: The car air conditioning system is designed to cool, heat, ventilate, and purify the air inside the vehicle. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The air conditioning system has become one of the indicators for assessing whether a car is fully equipped. 2. Avoid turning on the air conditioning immediately: In summer, the temperature difference between the inside and outside of the car is significant. When entering the car, it is not advisable to set the air conditioning to a very low temperature immediately. Instead, use high airflow with natural wind to dissipate the heat inside the cabin first. Then, do not close all the windows completely; turn on the air conditioning and wait until your body gradually adapts before adjusting the air conditioning to the desired temperature and closing the windows. This way, your body won't experience discomfort due to the sudden drop in external temperature.
