What kind of air is blown without AC?
2 Answers
Without AC, the air blown is natural air. Here is an introduction to the air conditioning system: 1. Buttons and components: The car AC button is the switch for the car air conditioning cooling system. Pressing the AC button will gradually lower the temperature inside the car. The car air conditioning cooling system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower, among other components. These parts are connected by copper pipes and high-pressure rubber hoses to form a sealed system. 2. Function: The car air conditioning system can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers and reducing driver fatigue, thereby improving driving safety. It generally includes a cooling device, heating device, and ventilation device.
When the AC is off, the fan blows outside air without any cooling or heating treatment—just natural airflow. For example, in summer, when the car gets scorching hot under the sun, turning off the AC means you’ll only get hot air blowing in, making it feel like opening an oven door. In winter, without the AC, the cold air rushing in can leave you shivering. However, this system is quite practical—whether it’s engine bay heat or cool outside air, it circulates naturally, saving you electricity or fuel costs. Just remember to adjust the fan settings: using the external air circulation mode speeds up air exchange, or control the fan speed and vent position to avoid blowing in too much dust. Overall, it’s a simple and effective way to save fuel, especially by avoiding excessive power drain from the AC compressor.
