美的风管机显示h5是什么意思

　　 演示机型：美的KFR-26GW/N8MJA3系统版本：变频空调

　　美的风管机显示h5是正在化霜的意思，化霜指空调已经没有在制冷，冷热交替的空调才会存在化霜的问题。当室外温度太高时，空调运行会和室外的空调设备进行一个热交换，这个热交换会导致空调出现结霜。

　　美的风管机化霜的注意事项：

　　h5故障码主要是想告诉我们空调正在自动的除霜，当除霜完成之后，h5这个故障代码就会消失，制冷和制热就会恢复正常，在化霜的过程中空调是可能会暂时性的停止制冷或者制热的。当空调长时间处于H5状态下，表明空调的除霜功能出现故障，除霜功能失效会导致以下不良影响：阻挡翅片之间的通道以增加气流阻力；增加热交换器的耐热性，降低热交换能力；蒸发温度降低，能效比下降，空调的运行性能直线下降，结霜严重甚至会引起空调无法正常运行。

美的风管机显示PL是什么意思

　　美的空调显示pl解释：pl故障是由于空调供电电压过高或者过低导致空调报故障。低压一般是由于空调的供电电压不稳造成的，像一般电压低于185的话，很多空调都会出现启动不起来的现象。空调出现高压情况，有可能是本身的供电电压过高造成的，空调本身的原因有可能是制冷剂过多或空调出现脏堵现象，让空调散热不良，出现高压保护性停机。

　　【英文介绍/For English】：

　　Demo model: Midea KFR-26GW/N8MJA3

　　System version: inverter air conditioner

　　The Midea air duct machine shows that h5 means defrosting. Defrosting means that the air conditioner is no longer cooling, and the air conditioner with alternating cold and heat will have the problem of defrosting. When the outdoor temperature is too high, the operation of the air conditioner will perform a heat exchange with the outdoor air conditioner equipment, and this heat exchange will cause the air conditioner to frost.

　　Precautions for Midea duct machine defrosting:

　　The h5 fault code mainly wants to tell us that the air conditioner is defrosting automatically. When the defrosting is completed, the fault code h5 will disappear, and the cooling and heating will return to normal. During the defrosting process, the air conditioner may temporarily stop cooling or heating. When the air conditioner is in the H5 state for a long time, it indicates that the defrosting function of the air conditioner is faulty, and the failure of the defrosting function will cause the following adverse effects: block the passage between the fins to increase the airflow resistance; increase the heat resistance of the heat exchanger and reduce the Heat exchange capacity; the evaporating temperature decreases, the energy efficiency ratio decreases, the operating performance of the air conditioner plummets, and the frost formation may even cause the air conditioner to fail to operate normally.
