What are the precautions for how to maintain the central air conditioner at home

Four seas network: central air conditioning installation is convenient and labor-saving. Central air conditioning has been covered in many families, so how do we maintain central air conditioning in our daily life? The following small edition summarizes several precautions, let's take a look.

1. Check the contact between the plug and socket of the air conditioner frequently. If it is found that the outgoing line or plug of the power supply is hot when the air conditioner is running, it may be because the electrical wiring is too thin or the contact between the plug and socket is poor. Take corresponding measures according to the situation.

2. The water system should pay attention to whether there is water leakage at the pipeline connection. In case of multi line system and air duct system, it is necessary to frequently observe whether there is refrigerant leakage at the interface of refrigerant pipeline of air conditioner. If any oil stain is found, it means that there is refrigerant leakage, and it should be treated in time to avoid insufficient refrigerant caused by long-term leakage, which may affect the refrigeration (heat) effect of air conditioner, or even damage the compressor.

3. Clean the filter screen regularly for water system and air duct fan system. Generally, clean once every 2-3 weeks. When cleaning, the filter screen shall be pulled out and the dust on the filter screen shall be removed with a dry soft bristle brush. You can also use clean water to wash away the dust on the filter screen. Dry before putting into the air conditioner. For the environment with more dust, the cleaning of the filter screen should be more frequent to avoid too much dust and affect the air volume of the air conditioner.

4. The condenser and evaporator coil of the air conditioner should be cleaned regularly for the multi connected household central air conditioner, and the dust on the coil should be cleaned by brush and vacuum cleaner. During cleaning, the brush and vacuum cleaner should be cleaned along the vertical direction of the coil. Do not clean along the horizontal direction to avoid damaging the fins of the coil.

5. When the air conditioner needs to be shut down for a long time (such as the seasonal shutdown of the air conditioner), the air conditioner shall be completely cleaned. After cleaning, only turn on the fan of the air conditioner, operate for about 2-3 hours, dry the inside of the air conditioner, and then cover the air conditioner with a dust boot.
