What are the Symptoms of Lack of Refrigerant in the Air Conditioner?

Air conditioners are a common cooling and heating equipment in our daily life. In summer, air conditioners are often used for cooling. The cooling of the air conditioner is inseparable from the role of the refrigerant. If there is no refrigerant in the air conditioner, the air conditioner will not be able to cool. But from the outside of the air conditioner, it is impossible to tell whether the air conditioner is short of refrigerant. If you want to know whether there is fluoride, you need to pay attention to some details.

1. If you want to judge whether the air conditioner is short of refrigerant, you can turn on the air conditioner first, wait for half an hour, open the air conditioner panel, remove the filter, and check whether there is dew or frost on the evaporator. If there is, the air conditioner is short of refrigerant.

2. You can also check the joints of the indoor unit and the valve of the outdoor unit. If there is oil in these two places, it may be that the air conditioner is short of refrigerant. Because fluorine and oil are miscible, fluorine leakage and oil leakage occur together, so there will be oil.

3. Another method is to turn on the air conditioner, and after a quarter of an hour, touch the valve of the outdoor unit to see if the temperature difference is large. If there is frost or dew, it may be due to the lack of refrigerant.

If the air conditioner is short of refrigerant, it can continue to be used, but without refrigerant, it cannot cool. In order to restore the cooling function of the air conditioner, it is necessary to add refrigerant to the air conditioner before it can be used normally. If the air conditioner is short of refrigerant, and the air conditioner continues to be turned on, the temperature of the air conditioner compressor will be high. After a long time, it will affect the performance of the compressor and cause damage to the compressor, so the compressor needs to be replaced.

There are many reasons for the lack of refrigerant in the air conditioner. It may be that the refrigerant is used up, which is normal. Another abnormal situation is that some parts of the air conditioner are damaged, resulting in the leakage of refrigerant and the lack of refrigerant.
