What happens when the air conditioner in the vehicle leaks?

In the process of driving, it is often found that the water leaks under the car when the air conditioner is turned on, which is actually a normal phenomenon and does not affect the use of the car. When the car air conditioner is refrigerated, the temperature of the evaporator and the air duct leading to the cockpit is very low, generally only about 0 5 degrees. At such a low temperature, the water vapor in the outside air will liquefy and condense on the pipe wall and shell of the air conditioner, and be discharged through the drainage holes in the chassis of the car.

As long as the water flowing is condensate, it is normal for the car air conditioner to flow a lot, and the more water that flows, the better the refrigeration effect of the car air conditioner. Under normal circumstances, there is a special drainage pipe under the co-pilot of the car, and the condensate of the car flows out through this part, if there is no way to drain it, it will cause dampness around the air conditioning system (inside the instrument panel) and corrosion of components.

Precautions for turning on the air conditioner of the vehicle.

The biggest benefit of the internal circulation of the air conditioner is to isolate the odor from the outside of the car or reduce the chance of inhaling dust, and it can reduce the power consumption of the air conditioner, but it cannot always be turned on the internal circulation. Because the internal circulation is the circulation of air in the car, the oxygen content in the car gradually decreases.

When the gasoline in the cylinder is not safe to burn, the carbon monoxide and carbon dioxide produced may leak into the cabin, resulting in the air in the cabin becoming very turbid, the oxygen is reduced, and the people in the cabin are easily sleepy.

The vehicle air conditioner is leaking, which is also often called by customers, and the vehicle is dripping from the air conditioner.

Reasons for water leakage when the vehicle turns on the air conditioner:

1. It is normal for the air conditioning pipe under the car to drip to the ground;

2. The drainage pipeline of the evaporator shell is blocked, and when the water level is too high and overflows;

3. The shell of the evaporator is damaged, or the drainage pipeline is loose;

4. Poor thermal insulation of the evaporator shell or the pipeline that transports cold air;

5. If the air conditioner is too cold, the moisture in the air will condense in the air outlet;

6. Continue to use the outside air circulation function, the high humidity outside the car air is constantly sent into the car, and the humidity in the car cannot be discharged to the outside of the car.

The air conditioner is open and the bottom of the car leaks normally.

Some car owners found that the car would leak water under the air-conditioning chassis, which is a normal phenomenon. If you drip water from the bottom of the car, it is usually air conditioner water with the air conditioner turned on, and if you drip water under the passenger seat, it is no problem. This has to do with the principle of air conditioning.

The compressor of the air conditioner compresses the refrigerant, which then expands through the valve, and the temperature of the refrigerant is lowered to release heat from the expansion. The refrigerant flows into the evaporator in the car, absorbs the heat of the air in the car through the contact between the evaporator and the air in the car, compresses it, expands it again, and circulates back and forth, taking away the heat of the air in the car little by little.

Normal. The reasons for the water leakage phenomenon in the car after turning on the air conditioner are as follows:

1. Because the car air conditioning system is equipped with an evaporator in the dashboard of the car, when the air conditioner is turned on (a c key on), the surface temperature of the evaporator is very low, and the water in the hot air in the car will condense on the surface of the heat-absorbing fin of the evaporator, and collect water droplets by the plastic shell of the evaporator to discharge the water out of the car with pipelines, if the vehicle is suspended in place for a period of time, sometimes you can see a pool of very clean and transparent water, please don't worry about the car failure, because the cooling water of the engine is usually antifreeze (green, red or blue).

2. There are times outside the compressor in the engine room (low-pressure area), and the water in the condensed air will drip on the ground (sometimes the amount of water is larger than the displacement of the evaporator).

3. If the low-pressure pipeline is not covered with insulating foam, the surface of the pipeline is easy to condense the moisture in the air, and the water droplets often condense and drip down along the lowest point of the pipeline.

4. The air humidity in the car is too high and the above problems are also prone to occur, there are two main reasons for the high air humidity in the car, the first reason is that the air circulation function outside the car is continuously used, and the air outside the car with high humidity is continuously sent into the car, and the humidity (moisture) in the car cannot be reduced (discharged to the outside of the car). The second reason is that the air tightness of the car body is poor, and the air outside the car with high humidity continues to seep into the car. Another typical condition in which the air humidity in the car is too high is the formation of water droplets around the exit, which can be observed by the car owner.

It is normal for the air conditioner to leak from the car because it needs to exhaust hot air, but it does not flow too much water, and too much may need to be checked.

Because the car's air conditioning system is equipped with an evaporator on the dashboard, 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 water in the hot air in the car will condense on the surface of the heat-absorbing fins of the evaporator, and the water droplets will be collected through the plastic shell of the evaporator and discharged out of the car through pipes.

Sometimes the beach is clean if the car is parked for a while. Clear water, don't worry about car breakdowns, because engine cooling water is usually antifreeze (green, red, or blue).

Outside the compressor (low-pressure zone) in the engine room, water from the condensed air also falls to the ground (sometimes the amount of water is greater than the displacement of the evaporator).

If the low-pressure pipe is not covered with insulation foam, the water in the air can easily condense on the surface of the pipe, and the water droplets are usually concentrated at the lowest point of the pipe.

Is it normal for a car to leak water when the air conditioner is on? Is it normal for a car to leak water when the air conditioner is on? The car is open and the dripping water is normal.

The dripping water is empty condensate, and there is a special drainage pipe under the passenger in front of the car, which is usually diverted through this disadvantage. When the air conditioner is cold, the temperature of the evaporator and the air duct leading to the passenger compartment is very low, generally only about 0 5 degrees Celsius. At this time, the water vapor in the air gas will liquefy and condense on the air conditioning pipe wall and shell due to the low temperature.

If the condensate is not discharged in time, it will cause the air conditioner to rot, and the surrounding area of the system (inside the dashboard) will be damp and the components will corrode. Therefore, at the beginning of the design, the car was designed to start empty and drip. The car air adjustment is controlled by AC buttons.

Turn on the air conditioner button and adjust the air to blow cold air. It is an abbreviation of airconditioner, which means empty sound, and can also be understood as cold wind. The AC switch controls the electromagnetic clutch.

For the car compressor to run, the electromagnetic clutch must be turned on when the power is on. There is no need to turn on the AC when it is empty in winter, because the heating of the car depends on the heat of the engine and has nothing to do with the compressor. The specific principle here is not a detailed description of hunger due to space limitations, and interested friends can view the information by themselves.

There are the following reasons for the leakage of the car air conditioner: 1. Improper installation of the body: the direction of the inclined pipe intersection of the indoor unit is too high.

2. Poor drainage pipe: due to the relaxation of the drainage pipe or the bending of hail Shixin into a wavy shape, the drainage source wheel is not smooth. 3. Dew condensation on the piping:

Because the insulation material on the pipe is too poor or too thin, condensation is caused when the refrigerant passes through the pipe. 4. Water dripping of heat exchanger: the heat exchanger is full of dust, causing the temperature of heat exchange to be uneven, and water droplets are generated in the middle of the heat exchanger, and the water droplets falling outside the water tray will drip into the room; The water droplets formed by the freezing and melting of the indoor unit caused by insufficient refrigerant in the air-conditioning system do not drip directly into the water tray.

Is it normal for a car air conditioner to leak? Is it normal for a car air conditioner to leak? Car air conditioner leakage, this is a normal poor branch phenomenon:

1. Since the automobile air conditioning system has an evaporator configuration on the car dashboard, when the air conditioner is turned on, the surface temperature of the evaporator will be relatively low; 2. The hot gas and water in the car will condense on the surface of the heat-absorbing fin of the evaporator, and the plastic shell of the evaporator will collect the water droplets and transport them out of the car; 3. If the vehicle is suspended in place for a period of time, sometimes you can see a pool of very clean and transparent water, please don't worry about the vehicle failure, it is because the cooling water of the engine, usually antifreeze, comes. @2019

1.Poor drainage: Long-term use of the drain pipe causes aging, bending loose or bending into a wavy shape, resulting in poor drainage and local blockage.

Solution: Or contact the manufacturer or a qualified air conditioner repairer to replace the drain pipe, the user can also buy an ordinary PVC pipe instead, but the construction of the outdoor unit part is a little difficult, and it is more troublesome to disassemble the protective tape.

2.Clogged drains: The drains leading out of the exterior are artificially blocked or the drains are blocked by stolen goods, resulting in the inability of condensation to drain out.

How to solve the problem of burying the group: If the building is designed with drainage pipes, it is necessary to focus on checking whether the drainage pipes are unblocked, and whether the drainage pipes and the air conditioning pipe are properly connected.

If the drainage pipe is installed by direct dripping, the possibility of the drainage pipe being blocked by dust is greater, and the drainage pipe can be flushed with a high-pressure water gun or tool to achieve the purpose of dredging.
