What is the normal pressure for a car's air conditioning system?

[LeLeonardo]

Under normal operating conditions of a general car's air conditioning system, the low pressure should be between 1.0-2.5 bar, and the high pressure should be between 15-18 bar. Here is some extended information on how to maintain a car's air conditioning system: 1. Comprehensive inspection of the air conditioning system: When using the air conditioning for the first time in summer, it is advisable to inspect the system first, such as checking the refrigerant and whether the air filter is too dirty through the reservoir, and whether there are any foreign objects in the radiator. 2. Pay attention to cleaning the air conditioning: Waiting until the air conditioning performance deteriorates before cleaning is not the right approach. The air filter should be replaced regularly. For example, in spring when there is more sand and dust, and willow catkins are flying around, these can stick to the filter, promoting bacterial growth and causing a musty smell in the air conditioning. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning.
