What Are the Causes of High Pressure in Car Air Conditioning?

[LeJoshua]

Introduction to the causes of high pressure in car air conditioning: Excessive refrigerant: Release part of the refrigerant or completely discharge and refill it; Excessive compressor oil: Discharge all the refrigerant, use a machine to extract the excess compressor oil, and then refill the refrigerant; Poor heat dissipation in the condenser: Clean the surface dirt and pipes of the condenser, and check the cooling fan to see if it operates at high speed; Expansion valve or expansion tube opening too small: Replace the expansion valve or expansion tube, thoroughly clean the air conditioning pipes, and replace the dryer if present. Car air conditioning generally includes refrigeration devices, heating devices, and ventilation devices.
