1, because the automobile air conditioning system is equipped with an evaporator on the instrument panel, when the air conditioner is turned on (the air conditioner key is turned on), the surface temperature of the evaporator is very low, and the moisture in the hot air in the car will condense on the surface of the heat absorption fin of the evaporator, and the water droplets will be collected through the plastic shell of the evaporator and discharged out of the car through the pipeline.
Sometimes the beach is clean if the car stops for a while. Transparent water, please don't worry about car trouble, because the engine cooling water is usually antifreeze (green, red or blue).
2. Outside the compressor (low pressure area) in the machine room, the water in the condensed air will also fall to the ground (sometimes the water quantity is greater than the displacement of the evaporator).
3. If the low-pressure pipeline is not covered with thermal insulation foam, the moisture in the air can easily condense on the surface of the pipeline, and water droplets are usually concentrated at the lowest point of the pipeline.
Extended data:
Modern automobile air conditioners have four functions, any of which is to make passengers feel comfortable.
(1) The air conditioner can control the temperature in the carriage, which can not only heat the air, but also reduce the temperature, so as to control the temperature in the carriage at a comfortable level;
(2) Air conditioning can exhaust moisture in the air. Dry air absorbs human sweat and creates a more comfortable environment;
(3) The air conditioner can inhale fresh air and has ventilation function;
(4) Air conditioning can filter air and remove dust and pollen from the air.
