How much does fuel consumption increase when using AC in summer?

[LeAna]

Using air conditioning in summer increases fuel consumption by about 2 units. This is because the engine operates under load after the AC compressor is activated. Here are some relevant points about using AC in summer: 1. Reason for increased fuel consumption: The car's air conditioning cooling system requires the engine to drive the compressor, which converts refrigerant from liquid to gaseous state to absorb heat during operation, consuming engine power! This consequently consumes fuel. 2. Amount of fuel consumed: The fuel consumption directly depends on the power consumed by the AC compressor. If the outside temperature is very high and the set temperature is very low, the AC compressor requires more power, resulting in higher fuel consumption.
