The whole car is a huge system, such as transmission system, air conditioning system, and so on. In the maintenance of automatic transmission, we should also take charge of the whole situation. Many years of maintenance experience tells Master Li that he has a lot of inspiration

是来自于实践的，自动变速箱维修过程中同样也是能够得到不少启发的，如空调系统的状况就可以通过自动变速箱维修中的视液窗来分析，这样对及时检测掌握空调系统的健康状况是至关重要的。

It comes from practice. In the process of automatic transmission maintenance, we can also get a lot of inspiration. For example, the condition of the air conditioning system can be analyzed through the liquid window in the automatic transmission maintenance, which is very important to timely detect and master the health condition of the air conditioning system.

以下是其中一部分在自动变速箱维修过程中得到的启发：

The following are some of the inspirations from the maintenance of automatic transmission:

若视液窗内清晰，而且出风口冷风效果不良，表明制冷剂不足。如果视液窗内布满油斑，则表明制冷剂泄漏殆尽。若视液窗内污浊，表明制冷

If the liquid window is clear and the cold air effect of the air outlet is poor, it indicates that the refrigerant is insufficient. If the sight glass is full of oil spots, it indicates that the refrigerant is completely leaked. If the liquid window is dirty, it indicates refrigeration

剂内润滑油过多。

There is too much lubricating oil in the agent.

自动变速箱维修专家分析得出结论，通过视液窗判断空调系统状态判断汽车空调系统工作状态的捷径之一，可以了解制冷剂量是否合适，制冷

Automatic transmission maintenance expert analysis concluded that through the liquid window to judge the state of the air conditioning system, one of the shortcut to judge the working state of the automobile air conditioning system, we can know whether the refrigeration dosage is appropriate, and the refrigeration efficiency is high

系统是否进入了空气等情况。若视液窗内有气泡或泡沫，蒸发器表面结霜，表明制冷剂不足。空调系统启动后，向冷凝器浇水，如果视液窗内无气泡出现，表明制冷剂过多。

Whether there is air in the system. If there is bubbles or foam in the liquid window, frost on the evaporator surface indicates that the refrigerant is insufficient. After the air conditioning system is started, water the condenser. If there is no bubble in the sight glass, it indicates that there is too much refrigerant.

在压缩机运转时，若视液窗内未见细小泡沫，表明制冷系统内没有吸入空气。在空调系统启动初始，视液窗内有气泡流动，片刻之后气泡消失

When the compressor is running, if there is no fine foam in the liquid window, it indicates that there is no air inhalation in the refrigeration system. At the beginning of the start-up of the air conditioning system, there are bubbles flowing in the sight glass, and then the bubbles disappear after a short time

，当提高转速或降低转速时，又出现气泡；关闭空调系统，视液窗内立即出现气泡，随后又消失。

When the rotation speed is increased or decreased, bubbles appear again; when the air conditioning system is turned off, bubbles appear immediately in the sight glass, and then disappear.
