Why does the car air conditioner cool slowly after being exposed to the sun?

[DelAubrey]

The reason why the car air conditioner cools slowly after being exposed to the sun is that the compressor protection device trips. Here is more relevant information: 1. Reasons and solutions for high pressure and overheating: (1) Too much refrigerant. Appropriately reduce the amount of refrigerant. (2) Poor heat dissipation. Check if the condenser tube is dirty and clean the condenser. (3) Blockage in the pipeline system. Refer to the pressure gauge to judge and eliminate, then reprocess the system. (4) Dust and scale accumulation on the evaporator or filter. The airflow becomes smaller, and the system pressure and temperature become unbalanced. Clean the evaporator or filter. (5) Lack of fluorine is also possible. When there is a lack of fluorine, the compressor exhaust temperature will overheat, causing the overload protection switch to trip. 2. Problems with the circuit: (1) Control circuit board failure. (2) Temperature sensor overload, incorrect information. (3) Loose or poor contact of power wiring. (4) The starting capacitor or compressor starting coil is burnt out.
