The reasons why the car air conditioning only cools when stepping on the accelerator are: 1. Insufficient battery voltage; 2. Slipping of the air conditioning compressor belt; 3. Damage to the air conditioning compressor. The car air conditioning system consists of a compressor, electronic control clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller, and control system, which are divided into high-pressure and low-pressure pipelines. The functions of car air conditioning are: 1. To adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to a better state, providing passengers with a comfortable environment and reducing travel fatigue; 2. To create good working conditions for the driver, serving as an important ventilation device for ensuring safe driving.
