no. 1 example

[0044] In a first exemplary embodiment of the present invention, a control method for reducing the frosting speed of an air conditioner is provided.

[0045] figure 1 It is a flowchart of a control method for reducing the frosting speed of an air conditioner according to the first embodiment of the present invention.

[0046] refer to figure 1 As shown, the control method for reducing the air-conditioning frosting speed of the present invention includes:

[0047] After the air conditioner operates in the heating mode for a first preset time, determine whether the air conditioner has a defrosting condition, and continue to determine whether the defrosting condition is over if there is a defrosting condition; and

[0048] When it is determined that the defrosting is over, the external unit is operated at a set speed higher than the normal speed for a second preset time, and after the second preset time, it runs at a normal speed.

Abstract

The invention discloses a control method and system for reducing a frosting speed of an air conditioner and the air conditioner. The control method comprises the steps of judging whether the air conditioner has a defrosting condition after the air conditioner operates in a heating mode for first preset time, and continuously judging whether defrosting is finished under a condition that the defrosting condition exists; and under the condition that the defrosting is determined to be finished, an outdoor unit operates at a set rotating speed higher than a normal rotating speed for second preset time, and operates at the normal rotating speed after the second preset time. Under the condition that the defrosting of the air conditioner is finished, the rotating speed of an outdoor unit fan is rapidly increased, and residual water and attached dust after defrosting on a heat exchanger are removed through a suction capacity of a draught fan so that the residual water and the attached dust do not exist on the heat exchanger before the air conditioner is started next time, at the moment, water in air condensed on the heat exchanger needs a certain period of time to be frosted, and thereforean effect of delaying a frosting speed is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and system for reducing the frosting speed of an air conditioner, and an air conditioner. Background technique [0002] With the development of society, people's living standards continue to improve, and the quality of life they pursue is getting higher and higher. Air conditioners have changed from a luxury product to a product that everyone can afford, so more and more people enter ordinary families. [0003] In a low temperature and high humidity environment, the outdoor unit of the air conditioner is prone to frosting, which greatly reduces the heating comfort of the air conditioner. Contents of the invention [0004] The problem solved by the invention is to avoid or delay the frosting process of the outdoor unit of the air conditioner. [0005] In order to solve the above problems, the present invention provides a control method, system and air ...
