空調故障分析的一般方法

空調器由制冷系統和電氣系統組成,它的運行狀態又與工作環境和條件有密切的關系,所以對空調器的故障分析需要綜合考慮½✡=】故障原因可分為兩類,一類為機外原因或人為故障(特別是電源是否正常),另一類則為機內故障½✡=】在分析處理故障時,首先應排除機外原因½✡=】排除機外因素後,又可將機內故障分為制冷系統故障和電氣系統故障兩類,一般應先排除電氣系統故障½✡=】至于電氣系統故障,又可從以下兩方面來查找:開關電源是否送電;電動機繞組是否正常½✡=】按照上述總的分析思路,便可逐步縮小故障範圍,故障原因也就自然水落石出了½✡=】二½✡=初步檢查制冷系統運行時,進行初查采用的是摸½✡=看½✡=聽½✡=查½✡=問的辦法½✡=】這些辦法既簡單而且有效½✡=】【摸】:摸一摸吸氣管½✡=排氣管½✡=壓縮機½✡=蒸發器出風口½✡=冷凝器等部位的溫度½✡=】正常時,吸氣低壓管冷,排氣管熱½✡=】壓縮機溫度一般在90~100℃,蒸發器管壁有水露,出風口有冷氣½✡=】憑手感便可判斷制冷效果的好壞½✡=】【看】:看看毛細管低壓部分的結霜情況½✡=】正常制冷時,在壓縮機運行之初,毛細管會結上薄薄的一層霜,隨後就逐漸化掉,但制冷劑不足或管路堵塞都會發生挂霜不化的現象

General method of air conditioning failure analysis

The air conditioner is composed of the refrigeration system and the electrical system, and its operating state is closely related to the working environment and conditions. Therefore, the failure analysis of the air conditioner should be divided into two types, one is the external cause or the human fault (especially the electric source is normal), the other is the internal fault. When analyzing and dealing with the fault, we should exclude the external factors and divide the internal faults into two types: the refrigeration system fault and the electrical system fault. Generally, the electrical system fault should be eliminated first, and the next two aspects can be found. In accordance with the general analysis idea mentioned above, the fault range can be gradually reduced, and the cause of the fault is also natural water falling out of two. The compressor temperature is normally at 90~100, the evaporator tube wall has water dew, and the outlet has the cold air. When the compressor runs at the beginning of the compressor, a thin layer of frost is formed at the beginning of the compressor, and then it is gradually reduced, but the phenomenon of the shortage of refrigerant or the pipe plug will occur.
