What is the car heating symbol?
1 Answers
The car heating symbol is represented by a red zone in some vehicles, where turning the knob gradually increases the temperature in the red area. In other cars, it is indicated by a "small sun" symbol. Here are some precautions for using the heating system: 1. Avoid direct airflow toward the body: Prolonged exposure to direct heat can cause driver fatigue and affect driving safety. Therefore, it is recommended to slightly open the window for air circulation when using the heater for extended periods, ensuring adequate oxygen levels inside the car to keep the driver alert. In fact, the car heater primarily relies on heat from the radiator, which is generated by the engine's circulating water, eliminating the need for the compressor to operate. Turning on the heater only requires adjusting the air conditioning controls, without activating the AC switch. 2. Avoid smoking in the car when the heater is on: With the heater running, the car becomes an enclosed space, creating an ideal environment for bacteria growth and spread. If someone smokes in the car, the amine and nicotine from the smoke can adhere to the evaporator surface. In situations where the air conditioning is not frequently used or during rainy weather, bacteria can proliferate on the evaporator surface, leading to air pollution inside the car when the air conditioning is turned on again. 3. Avoiding the heater due to fear of window fogging: Typically, the large temperature difference between the inside and outside of the car in winter causes condensation on the windows. Some drivers, concerned about fuel consumption, refrain from using the heater and instead open all windows for ventilation until the fog clears before closing the windows and turning on the heater. However, this approach only leads to repeated fogging. The correct method is to direct the heater airflow toward the fogged glass, which will clear the condensation within minutes. This way, passengers avoid cold drafts, and the fog is less likely to reappear.
