Summer is here, the weather is very hot, the temperature is very high, this weather car does not turn on the air conditioning, minutes to make people hot and dizzy. But some people will find that the car inside the air conditioning on a hot day, there will be a smell of dirty water like soaking a long time dirty clothes, so that people feel less comfortable.
So how does this odor come about? How to solve this odor?
The reason for the odor
In the last time you turn on the air conditioning, the air conditioning inside is wet, when the car puts a night, you start the air conditioning, in the air vent can smell inside the smell of water vapor.
Meanwhile, when you turn on the air conditioner in the summer, the air conditioner in the car is going to first blow the hot air inside the car through the blower to the evaporator box, and the temperature on this evaporator box is relatively low, so when the hot air passes through the evaporator box, it will condense a lot of water droplets because of the coldness.
These water droplets together, that is to say, will precipitate a lot of water, when we drive to the destination, get out of the car will turn off the air conditioning.
But this time, the evaporator box on the water droplets have not been completely evaporated, coupled with the car's air conditioning to absorb the outside air, will bring some of the impurities in the air dust and so on, these impurities dust will not evaporate and water mixed together, in the evaporator box to form a wet environment.
Then wait until the next time we open the air conditioning, through the blower, drum to the evaporator box of hot air will pass through the evaporator box on such a wet environment, so that the air discharged with a wet environment inside the air with the dust impurities and water vapor and other things.
This produces the odor we smell similar to dirty water. If you are in the south, especially in April and May of the rainy season, and even smell similar to the smell of mold, people feel very uncomfortable.
Ways to eliminate the odor
So how should you eliminate this odor? Meow teaches you two tricks, you just need to remember to do these two things.
First of all, when we drive from the destination is about only one or two minutes away, this time the air conditioning is turned off first, so that the evaporator box stops working, turn off the air conditioning, the temperature on the evaporator box will slowly return to normal.
Then, we have to open the external circulation mode, so that the hot air outside the car again through the evaporator, using hot air to evaporate some of the water droplets left on the evaporator, the water droplets left on the evaporator is evaporated, the next time we turn on the air conditioning, there will be no odor.
Finally
Therefore, when the summer open air conditioning car odor, as long as when the air conditioning again, a few minutes before stopping to turn off the air conditioning, open the external circulation mode, can be a good solution to this problem.
