How to heat the car air conditioner?

1, automobile air conditioning heating comes from the heat generated when the engine is working.

2. When the cooling system of the engine radiates heat to the engine, the radiated heat is sent into the car through the fan to form warm air; When the warm air is not used, the fan stops running, the hot air port is closed, and the heat emitted will be completely dissipated into the atmosphere. Therefore, the car heater belongs to waste recycling and will not consume oil.

3. In the cold season, it is necessary to quickly increase the temperature inside the car. When the car starts, the engine starts to warm up. After the engine temperature indicator reaches the middle position, first turn on the warm air conditioner, and set the air circulation to external circulation, so that the cold air in the car can be discharged outside the car. After waiting for 2 to 3 minutes, set the air circulation to internal circulation.
