What are the reasons for the poor cooling of a truck's air conditioning?

The reasons for the poor cooling of a truck's air conditioning include insufficient refrigerant, leaks in the air conditioning system, poor heat dissipation of the cooling system, clogged air filters, and compressor failure. Below are detailed explanations for the poor cooling: 1. Insufficient refrigerant: A lack of refrigerant results in poor cooling performance. Refrigerant needs to be replenished. The radiator and condenser are crucial components for heat dissipation in the vehicle. If they are too dirty, it will lead to poor heat dissipation, causing the engine to overheat and directly affecting the air conditioning's cooling efficiency. 2. Clogged air filter: A clogged air filter affects the airflow volume. The air filter's function is to prevent dust from entering the vehicle. Prolonged use can lead to dirt, odors, and even blockages in the air filter. When the filter is clogged with dust and debris, it severely reduces the airflow from the air conditioning. This results in high fan speed settings producing loud noise but minimal actual airflow, significantly reducing the output of cold air and impairing the cooling effect.
