Document Type and Number:
WIPO Patent Application WO/2021/233463
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of air conditioners, and specifically relates to a control method for an air-suction-type air conditioner. The present invention aims to solve the problem of an electric control module of an existing air-suction-type air conditioner being prone to short circuiting due to condensation under a refrigeration working condition. With regard to this aim, the air-suction-type air conditioner of the present invention comprises an indoor unit and an outdoor unit, wherein the indoor unit comprises an indoor heat exchanger and an indoor fan that are sequentially arranged in an air output direction, and an electric control box which is arranged on the side close to the indoor fan, with the the electric control box being provided with a heat dissipation component; and the outdoor unit comprises a variable-frequency compressor. The control method comprises: under the condition where an air conditioner runs in a refrigeration working condition, acquiring the temperature of a heat dissipation component and the internal temperature of an electric control box; and according to the temperature of the heat dissipation component and the internal temperature of the electric control box, selectively adjusting the rotation speed of the indoor fan and/or the frequency of the variable-frequency compressor, such that the problem of an electric control module failing, or even short-circuiting and burning out caused by the heat dissipation component being prone to creating condensation is solved to the maximum extent, thereby guaranteeing stable operation of the air conditioner.
