What Causes Low Low Pressure and Normal High Pressure in a Car's Air Conditioning System?

[LaMaci]

Car air conditioning low pressure is low and high pressure is normal because: the refrigerant or the air conditioning pipeline is blocked. The solution is: check and unblock the pipelines in the air conditioning system, and then test the air conditioning pressure through a pressure test. Car air conditioning is the abbreviation of car air conditioning device, which is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to a better state. The functions of car air conditioning are: 1. To provide a comfortable riding environment for passengers and reduce travel fatigue; 2. To create good working conditions for drivers and ensure driving safety. The working principle of car air conditioning is: the compressor compresses the refrigerant into a high-temperature and high-pressure liquid, which becomes a medium-temperature and low-pressure liquid after being cooled by the air conditioning radiator, and then becomes a low-temperature and low-pressure gas after being throttled by the expansion valve.
