Does Using Air Conditioning Consume a Lot of Fuel?

[McBrody]

Cooling consumes more fuel, while heating consumes very little and can be negligible. Here are some related extended information: 1. Cooling Principle: Cooling is a process completed by the compressor, which requires fuel consumption and can also affect power during driving. 2. Heating Principle: Heating involves blowing the engine's heat into the car through a fan. In other words, heating utilizes the car's waste heat to achieve temperature rise. The heat source for warm air is not the compressor (the compressor cannot provide heat), so there is basically no energy consumption and no additional load on the engine. Therefore, heating does not have fuel consumption issues. Of course, it is not absolutely zero energy consumption, as the operation of motor equipment like the fan always involves some energy consumption, but it is negligible.
