Embodiment Construction

[0056] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the present invention is described in conjunction with the embodiment in which the compressor is provided with two frequency-up stages, this arrangement is not static, and those skilled in the art can also apply the method of the present invention to Applied to other application scenarios, such as the compressor can also set three or more up-converting stages.

[0057] First refer to figure 1 , figure 1 It is a schematic flowchart of the control method of the air conditioner in the cooling mode of the present invention.

[0058] Such as figure 1 As shown, in order to solve the problem of poor rapid cooling effect due to...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method and system for an air conditioner under a refrigerating mode in order to solve the problem that in an existing air conditioner turning-on frequency-increasing control method, the frequency increasing time is long, and thus the rapid refrigerating effect is poor. The control method comprises the steps that an external draught fan is started and speeded up till a first target rotating speed is achieved; the opening degree of an expansion valve is adjusted to be a first target opening degree; whenthe external draught fan and / or the expansion valve reach / reaches the preset conditions, a compressor is started; and the compressor is subjected to staged continuous frequency increasing according tomultiple set speeds. Through the arrangement mode, the frequency increasing time of the compressor can be greatly shortened while normal oil returning of the compressor is ensured, the purpose of rapid refrigerating is achieved accordingly, the comfort of the air conditioner is improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and system in cooling mode. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking an air conditioner as an example, in order to meet the needs of users for rapid cooling and thus bring a more comfortable experience, the existing air conditioners usually increase the frequency of the compressor to a higher frequency when they are first turned on. When the compressor is running, the refrigerant in the compressor will be quickly discharged and circulated in the piping system. During the circulation process, the lubricating oil will be discharged from the compressor together with the refrigerant and enter the pipeline. Only when the discharged lubricating oil returns to the compre...
