How to Turn on the Rear Air Conditioning in Mercedes-Benz GLA200?
1 Answers
To turn on the air conditioning, simply press the AC switch. The AC button controls the air conditioning compressor. In summer, when using the air conditioning, press the AC button to activate the cold air. However, the warm air utilizes the internal heat circulation of the car and does not require the air conditioning compressor to be activated. Therefore, to turn on the warm air, you only need to adjust the air conditioning controls without pressing the AC switch. Additional relevant information is as follows: Note 1: The working principles of car warm air and cold air are different. Cold air is generated by compressing the refrigerant to liquefy and then vaporize it, absorbing a large amount of heat from the air. When the cold air is turned on, the compressor pulley drives the compressor, increasing the engine load and consuming a certain amount of fuel. Note 2: Warm air comes from the heat generated during engine operation. When the engine's cooling system dissipates heat from the engine, a fan directs this heat into the car to create warm air. When the warm air is not in use, the fan stops, and the warm air vent closes, allowing the heat to dissipate completely into the atmosphere. Therefore, car warm air is a form of waste heat recycling and does not consume fuel.
