What Are the Reasons for Poor Air Conditioning Performance in Vans?

[AaliyahFitz]

The reasons for poor air conditioning performance in vans are as follows: 1. Condenser cooling issues: The condenser located in front of the car engine can have its cooling efficiency reduced if its surface is covered with oil, dirt, catkins, or other debris. Additionally, faults in the cooling fan, such as a loose drive belt, reduced fan speed, or high-speed fan issues, can also lead to decreased condenser cooling performance. 2. The need to replace the air conditioning filter: The primary function of the air conditioning filter is to filter out impurities like dust, pollen, and moisture from the air. Over time, it will inevitably become clogged with dirt. If not cleaned or replaced in time, it will result in reduced airflow, poorer cooling performance, and even emit unpleasant odors. 3. Long-term use of external circulation: External circulation draws air from outside the vehicle, passes it through the condenser, and then into the cabin. If external circulation is used for a prolonged period, continuously drawing in high-temperature outside air, the cooling effect will certainly be worse than using internal circulation.
