Why can't the car air conditioner switch the airflow direction?
1 Answers
The reasons why a car air conditioner cannot switch airflow direction are as follows: Insufficient refrigerant: There is usually minor leakage in the air conditioning pipelines or condenser, causing refrigerant insufficiency after some time, requiring manual replenishment. Expansion valve or evaporator coil blockage: This leads to abnormal internal pressure, necessitating repair at a service center. Dirty condenser: The main purpose of the condenser is heat dissipation. In spring, it easily accumulates substances like willow catkins, leading to poor cooling performance. Air conditioning system pipeline leakage: This causes abnormal refrigerant evaporation or water ingress into the pipelines, resulting in poor refrigerant circulation, increased resistance, and ultimately the air conditioner's inability to cool.
