Does Using the Car's Air Conditioner for Heating in Winter Consume More Fuel?

[SanDallas]

Using the car's air conditioner for heating in winter does not consume more fuel. The reason is: the warm air comes from the heat generated by the engine during operation. After the engine's cooling system dissipates heat from the engine, a fan directs this heat into the car's interior, creating warm air. The function of the car's air conditioning system is: to provide a comfortable environment for passengers, reduce travel fatigue, create good working conditions for the driver, and ensure driving safety. The method to turn on the car's air conditioning for heating is: 1. Start the engine for preheating and wait until the engine temperature gauge reaches the middle; 2. Turn on the heating air conditioning and set the air circulation to external circulation to expel the cold air from the car; 3. After 2 to 3 minutes, set the air circulation to internal circulation.
