What's the situation when the air conditioner doesn't cool? What causes it

Usually, when there is a problem with the air conditioner, it has to be overhauled. For example, what should I do if the air conditioner doesn't cool after a long time? What causes it? Recently, Xiaobian encountered the problem that the air conditioner is not refrigerated, so we specially asked professionals to study a lot, and listed the following six reasons why the air conditioner is not refrigerated. Let's have a look

Reason 1: the power of the air conditioner is not enough. When you buy the air conditioner, you sometimes ignore the power of the air conditioner. The size of the room area, the length of the sunward time and the number of families all affect our choice of the air conditioner. If your room area is relatively large, but the number of air conditioners you choose is very small, then it is easy to cause the cooling effect of the air conditioner If it's not obvious, then you may think that your air conditioner is out of refrigeration. The size of the room area and the number of air conditioning match, air conditioning can fully show its superior cooling effect.

Reason 2: the power supply voltage fails to meet the air conditioning start-up requirements. In summer, the residential power consumption is very large. Therefore, when using air conditioning, the power supply voltage may be unstable. If the power supply cannot reach the normal voltage, then the working efficiency of air conditioning will be affected. Although the current variable-frequency air conditioning can operate in low-voltage environment, but when the power supply voltage is unstable or insufficient, the variable-frequency air conditioning can do nothing.

Reason 3: when the air conditioner has insufficient or leaking refrigerant, the compressor is idling during operation. As soon as the air conditioner is used for a long time, its refrigerant may be insufficient. At the same time, if there is a leak between the air conditioner pipes, the refrigerant will run out of the leak, causing the air conditioner to not operate normally. At this time, you will feel that your air conditioner is not refrigerated. If you want your air conditioner to operate normally, it is better to add some refrigerant to the air conditioner If there is a leak, it should be repaired first and then added with refrigerant.

Reason 4: the outside temperature is too high. You should know that the air conditioner outdoor unit should be far away from the use environment of the outdoor unit, or keep the air circulation around the outdoor unit of the air conditioner. If the outdoor unit of the air conditioner is placed in the area with high ambient temperature, the heat emitted by the air conditioner radiator will not be able to fully flow away, the burden of the air conditioner compressor will be heavier, and the cooling effect of the air conditioner will be worse.

Reason 5: the air conditioner has not been cleaned and maintained for a long time, and it needs to be maintained regularly after being used for a period of time. If the air conditioner is not cleaned for a long time, dust will accumulate in the air conditioner, which will not only affect the cooling performance of the air conditioner, but also block the air outlet and water outlet pipe of the air conditioner due to too many sundries in the air conditioner, making the air outlet of the air conditioner poor and the drainage not smooth, At the same time, the bacteria inside the air conditioner will continue to grow, and enter the room in the process of air supply, which will affect the health of the human body and cause the user to suffer from air conditioning disease.

Reason 6: the connecting pipe between indoor unit and outdoor unit is too long. In general, when the indoor and outdoor units of air conditioner are installed, the connecting copper pipe should not be too long. The proper connecting copper pipe of the internal and external units can not only reduce the installation cost, but also affect the cooling effect of the air conditioner. In general, the maximum length of connecting pipes between indoor and outdoor units shall not exceed 8 meters, and the length of connecting pipes of air conditioners with more than 2 pieces shall not exceed 15 meters, so as to ensure good refrigeration effect of air conditioners.
