Does the car's heating air conditioning consume fuel?

[Felicity]

Using the car's heating system does not consume fuel. The details are as follows: 1. The warm air comes from the heat generated by the engine during operation: After the engine's cooling system dissipates heat from the engine, the fan directs this heat into the car to form warm air; when the heating is not in use, the fan stops, and the heating vent closes, allowing all the dissipated heat to be released into the atmosphere. Therefore, the car's heating system recycles waste heat and does not consume fuel. 2. The cold air is formed by compressing the refrigerant to liquefy and then vaporize it, absorbing a large amount of heat from the air; when the air conditioning is turned on, the compressor pulley drives the compressor to work, increasing the engine load and consuming a certain amount of fuel.
