What Causes Uneven Airflow in Car Air Conditioning?

[AlyssaAnn]

Uneven airflow, where one side has stronger airflow than the other, may be caused by the evaporator on one side icing up. Here are some precautions for using car air conditioning: 1. Turn off A/C during startup and rapid acceleration: Since the air conditioning (non-independent type) consumes some engine power when turned on, it's best to turn off the A/C during vehicle startup and rapid acceleration, and then turn it on after the vehicle is moving. This prevents insufficient engine power during acceleration and startup while also saving fuel. 2. Avoid setting the air conditioning temperature too low: Many drivers prefer setting the temperature very low in summer, thinking it's more comfortable. However, this is a misconception because excessive temperature differences between inside and outside the car can easily lead to the driver catching a cold. Additionally, excessively low temperatures may increase the risk of arthritis for passengers. Normally, the cabin temperature should be 5°C to 6°C different from the outside temperature. 3. Adjust the air vent direction: Based on the principle that cold air sinks and hot air rises, when using the air conditioning, set the vents upward when cooling and downward when heating.
