Sihaiwang: air conditioning has become a necessary artifact in the hot summer. Believe that many people have air conditioning dependence in summer! Therefore, good operation of air conditioning in summer has become a necessary condition. If there's a breakdown, you're going to sweat. General air conditioning refrigeration will run for a period of time before the shutdown, but recently there are always netizens reported that sometimes the air conditioning refrigeration just a few minutes before the shutdown, so what's the matter?
The air conditioner will shut down soon
1. The automatic mode may be turned on. When the set temperature is close to the room temperature, it will automatically stop when the set temperature is reached. It is false that the air conditioner will stop when it is opened. In fact, there is no fault in the air conditioner.
2. The voltage is abnormal and unstable. Compressor over-current protection. It is recommended to replace a voltage regulator.
3. If the outdoor temperature is too high, it will also cause protection shutdown. When the outdoor temperature is more than 40 degrees, it can not make heat normally, which is easy to cause high temperature protection of air conditioning.
4. If the indoor sensor fails, if the air conditioner fails to sense the indoor temperature, it will automatically shut down and display the failure code.
5. It may be that the refrigerant is insufficient. When the refrigerant is insufficient, the exhaust temperature of the compressor is overheated, which is easy to trip the overheated load protection switch.
Causes of frequent start of air conditioning refrigeration
1. The air conditioning compressor just started to cool, after a while, it will not cool. Generally, the pipeline pressure is abnormal or the compressor starter is damaged. There are many reasons for the abnormal pressure of air conditioning pipeline, such as dirty indoor and outdoor units, dirty filters, slow fan speed, poor temperature exchange, four-way valve cross-talk, too much fluorine, compressor failure, etc.
2. Of course, there is also the possibility that the set temperature is too high. Soon after the air conditioner is turned on, the set temperature is reached. In addition, the room insulation may not be good, and the air conditioner runs too fast, which will lead to frequent start of air conditioning refrigeration.
Generally, the air conditioner will run for a period of time before it will shut down. But sometimes the air conditioner will shut down before it starts for a few minutes. What's the matter?
The reason of poor cooling effect of air conditioning
1. The temperature setting is too high. The cooling effect of air conditioner is directly related to the set temperature. If the air conditioner is set to 30 ℃ when the air conditioner is turned on in hot days, the cooling effect of the air conditioner must be very poor.
2. The air conditioning refrigerant is too little or leaks, resulting in the air conditioning working pressure is not enough, resulting in the air conditioning refrigeration effect will not be good.
3. The long-term use of air conditioning results in the aging of the internal valve plate of the compressor, resulting in the decline of the transmission power of the compressor, resulting in the poor refrigeration effect of the air conditioning.
4. The air conditioning refrigeration is normal, but the filter screen of the air conditioning has not cleaned the dust for more than half a month, and the dust blocks the filter screen, resulting in the reduction of the circulating air volume, that is, the amount of air-conditioner blown out is not enough, and the refrigeration effect is poor.
5. Many obstacles may be placed at the air inlet and outlet of the air conditioner, which will affect the cooling effect of the air conditioner.
