Embodiment Construction

[0049]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.

[0050] First refer to figure 1 , figure 1 It is a schematic flow chart of the control method of the air conditioner in the cooling mode in the cooling mode according to the present invention.

[0051] Such as figure 1 As shown, in order to solve the problem of po...

Abstract

The invention relates to the technical field of air conditioners, in particular to a method and a system for controlling an air conditioner in a refrigeration mode. The method and the system aims to solve the problem that in an existing method for controlling start-up and frequency rising of an air conditioner, the fast refrigerating effect is poor because the frequency rising time is long. The control method comprises the following steps: the opening degree of an expansion valve is adjusted to a first target opening degree; in the process of adjusting the opening degree of the expansion valveto the first target opening degree, a compressor of the air conditioner is started; the compressor is enabled to continuously raise frequency in stages according to a plurality of set speeds. According to the method and the system, the compressor is enabled to continuously raise frequency at different frequency rising speeds in stages after being started, the frequency rising time of the compressor can be greatly shortened while the normal oil return of the compressor is guaranteed so that the purpose of rapid refrigeration can be achieved, the comfort of the air conditioner can be improved,and the user experience can be 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...
