However, in the heating process, especially in the central and south areas of China, such as Sichuan and Chongqing, when the outdoor temperature is lower than 0 ℃, the frosting phenomenon occurs on the heat exchanger in the air conditioner outdoor unit. And the frost layer becomes thicker and thicker, and when the outdoor unit of the air conditioner is completely blocked by the frost layer, the outdoor heat exchanger cannot exchange heat with outdoor air, so that the refrigerant cannot be evaporated, and the air conditioner is stopped due to the low pressure inside the distribution pipeline. Therefore, it is necessary to cope with the frost formation phenomenon on the outdoor unit of the air conditioner.
The prior defrosting method mainly comprises four-way valve reversing defrosting, electric heating defrosting, hot gas bypass defrosting and mixed defrosting. Some defrosting methods are widely used, such as an electric heating defrosting method and a four-way valve reversing defrosting method, the two defrosting methods have simple structures and technologies, do not need to change an air conditioning system too much, and are stable to use, so the defrosting method is widely applied. But the disadvantages are also obvious: firstly, energy consumption is increased; secondly, the defrosting efficiency is lower. And is not suitable for application in medium and large-sized air conditioning systems. Other defrosting methods, such as bypass defrosting and mixed defrosting, have ideal defrosting effect, but have the following problems of complicated structure, need of improving the system, and addition of various sensors and branches. This inevitably increases the investment costs and energy consumption, and the complexity of the system reduces the stability and increases the maintenance costs accordingly. In order to overcome the above technical defects, an effective technical measure is urgently needed to solve the frosting phenomenon of the outdoor unit of the air conditioner so as to ensure the normal operation of the air conditioner under the condition of low outdoor temperature.
