空调常见故障大全及解决方法

 Air conditioning can be said that we now have the necessary family furniture, air-conditioning is a lot of common failures, air-conditioned common fault then do it, though we can see the air-conditioned figure, it has gradually entered our lives. However, if the air conditioning is broken and something goes wrong, what should we do?
空调可以说是我们如今家庭必备的家具，空调常见故障是很多的，那么空调常见故障该专门办呢，虽然我们都可以见到空调的身影，它已经渐渐的进入了我们的生活当中。但是，如果空调坏了，出现故障了，我们该怎么办呢？家电网(www.020883.com)介绍空调常见故障大全及解决方法

空调常见故障

空调常见故障—空调工作原理介绍

Inverter air conditioner are equipped with frequency converter, the frequency controller is how to work? The voltage of 220V and frequency of 50Hz in China is rectified and filtered to obtain about 310V DC. After the DC is inverted, the inverter power supply used to control the operation of the compressor can be obtained, which can change the frequency of 50Hz grid 30-130 Hz, inverter air conditioner is an air conditioner using inverter compressor and fuzzy control technology, according to the indoor temperature changes, adjust the cooling rate. A 15 square meters of room, inverter air conditioner than fixed frequency thermostat speed 6 to 10 minutes. After reaching the set temperature, inverter air conditioner can only operate at a low speed of 10% of the fixed-frequency air conditioner to adjust the slight loss of temperature and maintain the constant temperature.

　　变频空调中都装有变频器，这个变频控制器是如何工作的呢？国内规定的电压220V，频率50Hz的电流经整流滤波后得到310V左右的直流电，此直流电经过逆变后，就可以得到用以控制压缩机运转的变频电源，这就能将50赫兹的电网频率转变为30-130赫兹，变频空调就是一种使用变频压缩机和模糊控制技术的空调器，能根据室内气温的变化，调节制冷速度。一个15平方米的房间，变频空调比定频式调温速度快6~10分钟。达到设定温度后，变频空调又能以仅为定频空调10%的功率低速运转，以调节温度细微损耗，维持恒温状态。

空调常见故障—空调故障分析介绍

通电开机，压缩机不转，室外机不工作：开机自诊断，发现运转指示灯均闪亮，由此判断故障出在HC(变频数据处理电路)模块。取下该模块，用万用表测其各端的直流电阻，发现其“＋”端电阻为无穷大，说明已开路损坏。更换一块变频板即可。

自诊断显示运转指示灯常亮，室外机不工作：根据故障现象，判断故障出在室内、外机间的信号线上。重新检查室内、外机间各信号线，发现室内、外机间4号信号线与2号电源地线插错，致使信号中断，机子进入自动保护。重新连接好室内、外连线，机器恢复正常。

接通电源，指示灯不亮，室外机不工作：由于电源指示灯不亮，初步判断故障出在电源电路。开机检查主机电源继电器能正常吸合，检查电源基板AC－1和AC－3插脚，发现AC－3插脚无电压，沿电路检查插座3P－1和滤波磁环，发现滤波磁环已损坏开路。更换滤波磁环即可。 

空调常见故障的解决方法小编就介绍到这里了，空调常见故障是比较多，但是我们也不要怕，也就不必等维修人员来维修，从而更快的使用回空调。不仅如此，消费者也应在平时的生活中对空调进行定期的保养，这样空调才能更加长久的使用
