Problems solved by technology
[0007] Embodiments of the present disclosure provide a control method and device for defrosting an air conditioner, and an air conditioner to solve the problem that the method of judging whether to exit the defrosting mode in the related art is too rough, which may easily cause the air conditioner to exit the defrosting mode in advance or in the absence of frost. If the defrosting mode is run under low temperature, it will cause incomplete defrosting or technical problems affecting the normal heating performance of the air conditioner.

The invention relates to the technical field of air conditioner defrosting, and discloses a control method and device for defrosting an air conditioner and an air conditioner. The control method comprises the steps of under the condition that the air conditioner needs to be defrosted, controlling the air conditioner to reduce the running speed of an outdoor fan and / or the running speed of an indoor fan; obtaining outdoor coil temperature and refrigerant liquid outlet temperature of the outdoor heat exchanger; and when the outdoor coil temperature and the refrigerant liquid outlet temperature meet the defrosting exit conditions, controlling the air conditioner to stop reducing the running speed of the outdoor fan and / or the running speed of the indoor fan. According to the control method, the time for the air conditioner to exit defrosting is comprehensively judged by utilizing the two parameters of the outdoor coil temperature and the refrigerant liquid outlet temperature of the outdoor heat exchanger, so that the control precision for controlling the air conditioner to exit defrosting is effectively improved; and through adjusting the running speed of the outdoor fan and the running speed of the indoor fan, the heat exchange rate of the corresponding heat exchanger and the external environment is changed, and the influence of the temperature environment on the frost degree isreduced.
Description
technical field [0001] The present application relates to the technical field of air conditioner defrosting, for example, to a control method and device for air conditioner defrosting, and an air conditioner. Background technique [0002] At present, most of the mainstream models of air conditioners have the heat exchange function of cooling and heating. Increase the temperature of the indoor environment; during the heating process of the air conditioner, the outdoor heat exchanger of the outdoor unit acts as an evaporator that absorbs heat from the outdoor environment. Affected by the temperature and humidity of the outdoor environment, the outdoor heat exchanger It is easy to condense more frost on the heater, and when the frost accumulates to a certain thickness, the heating capacity of the air conditioner will become lower and lower. Therefore, in order to ensure the heating effect and avoid excessive frost condensation, it is necessary to The outdoor heat exchanger is ...
