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

[MacLeila]

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, if its surface is covered with oil, mud, willow catkins, or other debris, its cooling capacity will decrease. Additionally, faults in the cooling fan, such as a loose drive belt, reduced fan speed, or high-speed fan issues, can all lead to a decline in the condenser's cooling ability. 2. Air filter needs replacement: The main function of the air filter is to filter out dust, pollen, moisture, and other impurities from the air. Over time, it will inevitably become clogged with dirt. If not cleaned and replaced in time, it will result in reduced airflow, poorer cooling effects, and even emit unpleasant odors. 3. Long-term use of external circulation: External circulation draws in air from outside the vehicle, which passes through the condenser before entering the cabin. If external circulation is used for a long time, continuously drawing in high-temperature air from outside, the cooling effect will certainly be worse than using internal circulation.
