What should I do if the central air conditioner leaks?

1. indoor unit deviation. The unstable installation of indoor unit causes displacement, and the unstable installation and fixation of indoor unit fixed hanging plate for a long time causes displacement, which leads to the high position of the outlet side of the drainage pipe and the difficulty of drainage; The horizontal position of the indoor unit is improperly installed, the horizontal position of the indoor unit is inclined, and the position of the pipeline intersection is too high, which leads to the blockage of condensate discharge.

Solution: move the air conditioner, re-calibrate the position of the air conditioner with ordinary liquid level, and trim or lower the outlet end of the air conditioner condensate pipe as much as possible.

2. Condensation on the pipeline. Due to the poor quality or thin insulation material on the pipeline, or incomplete packaging, when the refrigerant in the pipeline passes through, it will cause condensation.

Solution: This is a common phenomenon of indoor pipeline dripping. When this happens, first take apart the tape and check whether the insulation material is aging or installed correctly. If cracks or thinning are found, they can be repackaged. At the same time, the aging adhesive tape can be replaced to maintain the tightness of the copper tube.

3. The drainage pipe is poorly drained or blocked. Because the drain pipe is aging, slack or bent into a wave shape, poor drainage is also easy to cause the phenomenon of air conditioning dripping. Secondly, the drain pipe leading out of the room is artificially blocked or the drain is blocked by stolen goods, which leads to dew condensation and cannot be discharged. Or the sewer is blocked by stolen goods, resulting in dew not being discharged.

Solution: If the drain pipe is aging or slack, it needs to be replaced. If it is blocked by dirt, just clean it up.

4. The heat exchanger drips water. If the heat exchanger is too dirty, it will cause poor drainage of the air conditioner. At this time, a lot of water will gather on the blades of the indoor unit and drip down. Or the uneven temperature of the heat exchanger caused by insufficient refrigerant in the air conditioner can also cause dripping.

Solution: clean the heat exchanger, which can be cleaned with cleaning agent, brushed gently with wool brush, or blown off by cold air with high-power blower. Of course, if it is a refrigerant problem (which can be measured by a pressure gauge), only professionals can be asked to add refrigerant.

5. Freon is insufficient.

When there is not enough freon, the air conditioner will leak. At the same time, when the air conditioner has poor refrigeration effect and long service life. This is also the first reason to consider when the air conditioner leaks.

Solution: Ask professional air conditioner maintenance personnel to add fluoride to the air conditioner.

6. The newly installed air conditioner extension drain pipe leaks.

The air conditioner was installed and debugged normally, but it leaked after a few days. When encountering this phenomenon, it is generally that the inclination of the air conditioning drain pipe is uneven when it is installed, and the rear end of the drain pipe is higher than the front end, so that a water suction place is formed in the middle of the drain pipe.

Solution: When installing the drain pipe, pay attention to keep it steady and not tilt.

7. The filter screen of the air conditioner needs cleaning. Dirt in the filter screen blocked the holes in the grid. At this time, the cold air could not be blown out and condensed on the grid. After a long time, water droplets will leak.

Solution: clean the filter of air conditioner.

Second, the central air conditioning daily maintenance methods

1. When the air conditioner is turned off for a long time (for example, the air conditioner is turned off seasonally), the air conditioner should be thoroughly cleaned. After cleaning, just turn on the fan of the air conditioner to run for about 2-3 hours, blow dry the inside of the air conditioner, and then cover the air conditioner with a dust cover.

2. Always check whether the electrical plug and socket of the air conditioner are in good contact. If the power cord or plug is found to be hot when the air conditioner is running, it may be because the wire is too thin or the plug socket is in poor contact, and corresponding measures should be taken according to the situation.

Solution measures.

3, water system should pay attention to whether the pipe joint leaks. If it is a multi-line system or a fan system, it is necessary to observe whether there is refrigerant leakage at the refrigerant pipeline interface of the air conditioner. If oil stains are found, it means that there is refrigerant leakage, and it should be handled in time to avoid long-term leakage leading to insufficient refrigerant, affecting the refrigeration (heating) effect of air conditioning and even damaging the compressor.

4, water system and duct machine system to clean the filter regularly. Generally, it is cleaned once every 2-3 weeks. When cleaning, pull out the filter screen and brush off the dust on the filter screen with a dry soft brush. You can also wash away the dust on the filter screen with clean water. Dry it and put it in the air conditioner for later use. For the dusty environment, the filter screen should be cleaned more frequently to avoid too much dust and affect the air volume of the air conditioner.

5. Multi-connected household central air conditioner should regularly clean the condenser and evaporator coil of the air conditioner, and clean the dust on the coil with a brush and vacuum cleaner. Note that brushes and vacuum cleaners should be cleaned along the vertical direction of the coil, not along the horizontal direction, so as not to damage the fins of the coil.

6. The air conditioner should be turned on in strict accordance with the operating procedures. It is forbidden to turn on the heating in summer or the cooling in winter, otherwise it will cause serious damage to the compressor and affect its normal use; After the air conditioner is turned on, the set temperature should be moderate, the refrigeration temperature should not be lower than 26℃, and the heating temperature should not be higher than 20℃, so as to avoid the air conditioner working for a long time and the compressor heating, which will affect the normal use.

7. Adjust the wind direction of the air outlet reasonably. The air outlet direction should be adjusted when the central air conditioner is cooling and heating. Generally, when the temperature drops in summer, the louvers at the air outlet are slightly raised, because the cold air is relatively heavy, the wind blows down, and the louvers are slightly raised to avoid direct blowing of cold air. In winter, air conditioning is just used for heating.

On the contrary, the hot air is relatively light, and the blinds should be perforated downward to ensure the heating effect.

8. Never switch the air conditioner on and off frequently, because the air conditioner needs to consume more electricity when it is started than when it is running.

To drive the operation of the air conditioner, it is necessary to set the service time and temperature requirements of the air conditioner appropriately.
