How to check the leakage of air conditioning refrigerant

1. The method for judging whether there is refrigerant leakage in the window air conditioner is as follows: first, remove the panel, turn on the air conditioner, and adjust the wind speed to low speed to see if the compressor is started. Usually, when the compressor starts, there will be a low vibration sound. If the compressor starts, touch the cold row or copper tube to see if it feels cold. If there is no ice at all, it may be that the refrigerant pipe is damaged and the refrigerant leaks. At this time, professional maintenance is needed.

2. Another case is that the copper tube is only half cold or 80% cold or 1/3 cold. If the feeling of blowing makes you feel cold enough, you need to replenish refrigerant, and the cost is as above. This situation is mostly caused by inadequate air conditioning maintenance.

3. The traditional split air conditioner can judge whether the refrigerant leaks. The method is as follows: first, open the panel of the indoor unit and remove the filter (note that the panel is open rather than removed). When the air conditioner is turned on, check whether the compressor and outdoor fan of the outdoor unit are running. If it is determined that it is running, all the cold copper pipes of the indoor unit are not cold, which may be that the refrigerant has completely leaked. In this case, technicians need to go to the office for repair. Check where the copper tube of the air conditioner leaks refrigerant.

Another common situation is the lack of refrigerant, which is very common. It is also half or one or two rows cold in the indoor mechanism, which will freeze. If it is driven for a long time, it will be blown by the wind and make an abnormal noise. You can also see that a thin copper tube will freeze in the outdoor unit. This is the lack of refrigerant. You need to ask a technician to replenish refrigerant in the office. This situation sometimes depends on whether the outdoor unit is too dirty. If it is too dirty, it should be maintained so that there will be no problem with the refrigerant.
