Does Using Air Conditioning in Summer Increase Fuel Consumption?

[DaisyDella]

Using air conditioning in summer does increase fuel consumption. Here is more information about car air conditioning: 1. Classification of Car Air Conditioning: Generally, based on vehicle configuration, it is mainly divided into manual air conditioning and automatic air conditioning. Adjusting the fan speed has no relation to the compressor. As long as the air conditioning is turned on for cooling, the compressor will always operate at full speed, so there is no such thing as fuel-saving or not. As for adjusting the temperature in manual air conditioning, it simply involves mixing more or less hot air with the cold air. In actual use, the interior temperature never reaches a level that would stop the compressor from running. Simply put, this type of fixed-displacement compressor runs at full speed once started and does not shut off. Even if the temperature is set higher, it will not save fuel. 2. Differences in Car Air Conditioning: Generally, manual air conditioning is equipped with a fixed-displacement compressor. Automatic air conditioning can also use a fixed-displacement compressor, operating on the same principle as manual air conditioning but with the addition of an automatic temperature control device. It can automatically select whether to blow "pure cold air" or "mixed cold and hot air" based on the difference between the interior temperature and the set temperature, and adjust the fan speed accordingly. Therefore, the set temperature has no relation to fuel-saving or not. As long as the air conditioning is on, it will consume more fuel.
