Why Does Hot Air Enter the Car When the Air Conditioner Is Off?
1 Answers
When driving without turning on the air conditioner, hot air may still blow from the vents, but this is actually a normal phenomenon. Specific reasons: The air intake for the air conditioner passes through the engine. When the engine is running, heat is carried by the air to the vents, so even when the air conditioner is off, the air blown out can be hot. Fuel-saving tips for using the car heater: There is a coolant temperature gauge on the car dashboard. When the needle reaches the middle position, you can use the heat generated by the engine to blow warm air into the car; although the car may feel warm when entered before starting, the air quality inside is very poor, and it can cause fogging on the windshield. After starting the vehicle, turn on the external circulation to maintain continuous air exchange inside the car.
