Problems solved by technology

[0002] When the air conditioner is in heating operation, the heat exchanger of the outdoor unit is frosted, resulting in poor ventilation of the outdoor unit. As the thickness of the frosting increases, the heat exchange efficiency of the outdoor unit decreases sharply, the heating capacity of the air conditioner decreases, and the comfort deteriorates.

Embodiment Construction

[0049] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] In the prior art, the method of reversing and defrosting is mostly adopted. This method has at least the following two defects: one is that the heat that can be absorbed is limited, resulting in a long defrosting time, and in the later stage of defrosting, due to the frosting of the indoor heat exchanger, the heat power that can be absorbed is smaller, which further prolongs the defrosting time. The frost time affects the comfort; the second is that there is a lot of frost on the indoor side, and it takes a long time for the heating operation to melt the frost on the indoor side after defrosting, which causes the temperature of the indoor heat exchanger to rise to the expected value after a long time, which affects the cooling system...

Abstract

The embodiments of the invention provide a defrosting control method and device, an air conditioner and a storage medium, and relates to the technical field of air conditioners. The method is characterized in that when the air conditioner enters a defrosting mode, an operation parameter of the air conditioner and a current current threshold value of a motor are obtained, an actual current threshold value of the motor is determined according to the operation parameter and the current current threshold value, and an input voltage of the motor is adjusted on the basis of the actual current threshold value and a preset reference rotating speed of the motor, so as to improve the heating power of a compressor. According to the method, the actual current threshold value of the motor is determined, and the input voltage of the motor is adjusted on the basis of the actual current threshold value and the preset reference rotating speed of the motor, so that an actual current of the motor is close to the actual current threshold value, and an actual rotating speed of the motor is close to the reference rotating speed of the motor; and therefore, the heating power of the compressor is improved in a defrosting process of the air conditioner, defrosting is accelerated, the defrosting time is shortened, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a defrosting control method and device, an air conditioner and a storage medium. Background technique [0002] When the air conditioner is in heating operation, the heat exchanger of the outdoor unit is frosted, resulting in poor ventilation of the outdoor unit. As the thickness of frost increases, the heat exchange efficiency of the outdoor unit decreases sharply, the heating capacity of the air conditioner decreases, and the comfort becomes poor. [0003] In the prior art, the defrost is usually defrosted by absorbing heat from the indoor side through the refrigeration cycle and melting the frost on the heat exchanger of the outdoor unit. However, this method has the disadvantage of reversing the defrosting time and affecting the heating performance. And other problems will bring bad experience to users. Contents of the invention [0004] The problem solved ...
