空调风量不足的维修方法!

  空调含空气的判断方法
  Judgment Method of Air Containing in Air Conditioning
  1,如果制冷系统有空气,则压力表指针摆慢,且振幅略大。若压力表指针摆较快,并且摆与活塞运动频率相同,振幅也较小,则是由压缩机排气不均,含空气引起的。
  1. If there is air in the refrigeration system, the pressure gauge pointer swings slowly and the amplitude is slightly larger. If the pressure gauge pointer pendulum is faster, and the pendulum moves at the same frequency as the piston, and the amplitude is smaller, it is caused by the uneven exhaust of the compressor, including air.
  2,空调压缩机的排气压力与撩拨温度均大于正常压力的温度,这也说明空调制冷系统中含有空气。
  2. The exhaust pressure and pulling temperature of air-conditioning compressor are higher than the normal pressure temperature, which also shows that air is contained in the air-conditioning refrigeration system.
  空调风量不足的维修
  Maintenance of insufficient air volume in air conditioning
  空调(风机)吹出的风量比正常情况下明显减少,是空调运行中的常见故障。分析其原因主要有以下几点:
  Air flow rate of air conditioner (fan) is obviously less than that under normal conditions, which is a common fault in air conditioning operation. The main reasons are as follows:

  1,电源线接错,造成反相转。这种故障大多是在维修空调时,由于停电检修,不小心或粗心把三相电源线相序接错造成。
  1. The wrong connection of the power supply leads to inversion. This kind of fault is mostly caused by inadvertent or careless misconnection of three-phase power supply wires during maintenance of air conditioning.
  2,风机皮带打滑,造成转速下降。由于空调的风机传动皮带因长期使用容易松动,甚至出现裂痕,使风机叶的转速下降,从而造成风量不足,只要调整(电机位置)或更换皮带即可。
  2. The belt of the fan slips, resulting in a decrease in speed. Because the air-conditioning fan drive belt is easy to loosen or even crack because of long-term use, the speed of fan blade decreases, resulting in insufficient air volume, as long as adjusting (motor position) or replacing the belt.
  3,风机风叶与轴坚固的制动镙钉松动。
  3. The strong brake pins of fan blades and shafts are loosened.
  4,因蒸发器、冷凝器、过滤网等脏或堵造成的风量不足。只要停机让它完全融霜便可以排除故障。
  4. Insufficient air flow due to dirty or blocked evaporators, condensers, filters, etc. If you shut down and let it defrost completely, you can get rid of the trouble.
  5,因蒸发器等结霜过厚(即发生抱冰)赞成的风量不足,只要停机让它完全融霜即可。
  5. Because the evaporator and other frost is too thick (that is, ice holding) in favor of insufficient wind, as long as the shutdown to allow it to completely defrost.
  6,因通风管道局部破损或堵塞造成风和风量不足。对此,应查出破损原因进行修复。若鼠害造成可在回风口安装防鼠网等避免故障发生。另外要定期进行清堵。保证风机正常运转。
  6. The air and air volume are insufficient due to local breakage or blockage of ventilation pipes. In this regard, the cause of damage should be found out and repaired. In case of rodent damage, the anti-rodent net can be installed at the return air outlet to avoid the occurrence of malfunction. In addition, blockage removal should be carried out regularly. Ensure the normal operation of the fan.
