Does the car air conditioner consume fuel or electricity?

[DelGiselle]

Car air conditioners consume fuel while household air conditioners consume electricity. The relevant introduction is as follows: 1. The air conditioning compressor is the heart of the air conditioner, the most crucial component for its operation, and also the part that consumes the most energy in the entire air conditioning system. In traditional fuel-powered vehicles, the compressor is often connected to the engine and driven directly by it, rather than being powered by electricity. This is why using the air conditioner consumes fuel instead of electricity. 2. The car air conditioner, like a household air conditioner, is a high-power electrical appliance. Under normal working conditions, the power of a car air conditioning compressor often exceeds 2kW. A typical car battery is 12V, and ordinary batteries simply cannot support such a high-power air conditioning compressor. Moreover, with the increasing quality of car configurations and the growing number of onboard electrical appliances, all rely on this battery for power supply.
