Abstract

The present application relates to a control method and device for defrosting an air conditioner and an air conditioner. The method includes: entering a defrosting working mode; adjusting the refrigerant flow rate of the i-th refrigerant flow path according to the refrigerant temperature of the i-th refrigerant flow path of the heat exchanger to be defrosted in the air conditioner. The control device is configured to execute the aforementioned method. An air conditioner includes the aforementioned control device. Enter the defrosting working mode, determine the flow rate of the refrigerant in the corresponding refrigerant flow path according to the refrigerant temperature of each refrigerant flow path, and perform targeted heat exchange on the heat exchange units corresponding to different refrigerant flow paths in the heat exchanger Adjust the amount to make the defrosting even.

Description

technical field [0001] The present application relates to the technical field of air conditioner defrosting control, for example, to a control method and device for air conditioner defrosting and an air conditioner. Background technique [0002] Along with the raising of living standard, air conditioner is used more and more generally. When the air conditioner is running in the heating mode, due to the influence of the outdoor ambient temperature and humidity, frost will form outdoors. If the defrosting is not complete after the air conditioner is frosted, the heating effect of the air conditioner will decrease, and the air conditioner will start irregularly. stop, resulting in poor user experience and affecting use. [0003] In addition, with the development of the self-cleaning technology of the air conditioner, the self-cleaning of the heat exchanger of the air conditioner is completed by means of accumulating frost on the surface of the heat exchanger and then defrostin...
