What is the Difference Between Manual and Automatic Air Conditioning in Cars?

[KinsleyLynn]

The differences between manual and automatic air conditioning in cars are as follows: 1. Operation Differences: Manual air conditioning can only adjust the airflow manually, but its operation is intuitive and easy to understand without overly complex functions, though it offers a single working mode. Automatic air conditioning does not require frequent adjustments; once the temperature is set, it automatically maintains the interior temperature at that level. It also intelligently switches between internal and external air circulation to ensure reasonable air quality inside the vehicle. 2. Fuel Consumption Differences: The compressor in manual air conditioning operates at a constant power, thus consuming engine fuel. Automatic air conditioning can adjust the temperature automatically. When the set temperature is reached, the compressor can pause or reduce its output power. If the temperature rises, the compressor restarts to maintain the set temperature, allowing the engine to save power when idling, thereby achieving fuel efficiency.
