What does max car button mean?

The max key of the car is the defogging function.

If the max button appears on the car air conditioning panel, and the button has a fan-shaped standard and is marked with a curve, then the button has a defogger function. The cooling function of the evaporator is used to remove water molecules in the air. When turning on the car air conditioner, adjust the air outlet to the windshield and let the compressor work. Turn the temperature button to the warm air position. The relative humidity of the air will decrease, and then Mix warm wind to remove water molecules in the air, thus playing the role of defogging and heating.

In addition, car air conditioner maxac stated that the ac button in the car is the car air conditioner refrigeration switch. When the weather is hot and you need to turn on the air conditioner to cool down, press the ac button. The indicator light on the button should light up, the car air conditioner refrigeration compressor starts to work, and the air outlet blows out cold air to reduce the temperature inside the car.

Introduction to the car defogging function

The car's defogging function acts on the windows at the front windshield and the windows at the rear windshield. If it is the car in front Window defogging is to use the air outlet of the air conditioner to blow out cold air or warm air, and then defogging.

If it is the rear window, it relies on electric heating to defog. We can see inlaid textures on the rear window, and these textures are electrically heated metal wires. When I usually use the defogging function, whether in summer or winter, I prefer to use cold air to defogging, because it can save fuel consumption and defogging quickly.
