What is the heating symbol in a car?

A "small sun" symbol is used to represent the heating function. Here are some precautions when turning on the heating: 1. Do not blow directly at the body: Blowing directly at the body for a long time can cause driver fatigue and affect driving safety. Therefore, it is recommended to open the window slightly to allow air circulation when using the heating for an extended period, ensuring sufficient oxygen levels in the car and keeping the driver alert. In fact, the main source of car heating is the heat from the radiator, which is generated by the engine's circulating water and does not require the compressor to work. Turning on the heating only requires adjusting the air conditioning buttons, and there is no need to turn on the AC switch. 2. Do not smoke in the car when the heating is on: After turning on the heating, the car becomes an enclosed space, creating an ideal environment for bacteria to grow and spread. If someone smokes in the car, the amines and nicotine in the smoke will adhere to the surface of the evaporator. When the air conditioning is not frequently used or during rainy weather, bacteria can proliferate extensively on the evaporator surface, causing air pollution inside the car when the air conditioning is turned on again.
When driving in the cold winter, I often use the car's heating symbol, which is usually a red fan-shaped icon or a wavy arrow pointing to the upper right, indicating the activation of the heating function. On the air conditioning panel, pressing it will blow warm air, helping to quickly warm up the interior. However, it's important to note that the heating system doesn't operate independently—it requires the engine to run for a while to be effective, as the heat comes from the engine's residual warmth. In contrast, the cooling button is the blue A/C key with a snowflake pattern, used to turn on the air conditioning compressor for cooling. I've also noticed that if you accidentally turn on both the cooling and heating functions simultaneously, the system might conflict, reducing efficiency. It's recommended to wait a few minutes after starting the car in the morning during winter before turning on the heating. This not only saves some fuel but also protects the blower motor. Developing a habit of regularly cleaning the air conditioning system prevents dust buildup that could block the warm air, ensuring a comfortable ride every time you hit the road.
As a long-time urban commuter, I rely on the heater symbol during my daily drives. It's a small fan-shaped icon, usually in red or orange, found on the car's center console. Pressing it releases warm air from the vents, alleviating the discomfort of cold weather. Practical use requires timing: wait five minutes after engine start-up before activating the heater to avoid blowing cold air prematurely, which wastes energy. It's separate from the defrost button, marked by a windshield icon for clearing fog. I've even advised friends not to disable the heater system in summer; occasional use prevents duct freezing. Remember, setting the temperature between 20-25°C is optimal—higher settings can overly dry the cabin air, affecting health. Mastering this small symbol's nuances ensures safer, more efficient driving.
