How to solve the leakage of Model Y air conditioner chassis?

Not only is Tesla leaking the air conditioner chassis. Almost all cars with air conditioners are leaking from the chassis. Not only does the car’s air conditioner leak, but the home’s air conditioner also leaks.

This is mainly caused by the working principle of the air-conditioning system. The cooling principle of the air-conditioning system is to rely on the volatilization of liquid refrigerant to absorb heat for cooling. The liquid refrigerant changes from liquid to gas in something called an evaporator.

This thing in the car is installed in the center console. The working principle is basically the same as the internal machine of our home air conditioner. Through a relatively large area of ​​heat sink and a back and forth pipeline, the liquid refrigerant is slowly turned into a gaseous state in the entire cycle of the pipeline. According to physical knowledge, the liquid substance is directly volatilized into The gaseous state needs to absorb a lot of heat, and the heat is taken away by the refrigerant in the pipeline, so the temperature of the evaporator itself will become very low. At this time, the air with a relatively high temperature will be turned into cold air by the evaporator when it blows through the evaporator to complete the refrigeration.

Of course, during the cooling process, some other physical reactions will also occur. For example, when the temperature of the water vapor in the hot air drops instantaneously, it will condense into water droplets attached to the surface of the evaporator. When there is too much water, it will leak down the evaporator. After the water condensed in the internal unit of the household air conditioner leaks, it is led to the outside through a drain pipe. Therefore, the water dripping from the external unit of the air conditioner we see every day actually comes from the internal unit.

The same principle applies in cars. If the water in the center console is not drained in time, it will accumulate inside the car, causing mold and peculiar smell. Therefore, in general, a drain pipe is made through the bottom of the evaporator to drain the water directly from the bottom of the bottom of the evaporator, which causes the bottom of the air conditioner to leak water. This is completely the effect of normal work, don't care.

The real scary thing is that the chassis does not leak water after the air conditioner is turned on. There have been such cases in the Tesla Model Y. Due to factory assembly errors, the water pipe did not drain the water, resulting in condensate in the _ span24span piles up in the chassis,In the end, the car owner heard the sound of running water and went to the service station to check before discovering the problem. Therefore, in the daily inspection, observing whether the air-conditioning water is discharged normally should also be used as the inspection range to judge the normal operation of the air-conditioning system.
