Embodiment Construction

[0063] 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.

[0064] First refer to figure 1 , figure 1 It is a schematic flowchart of the control method of the air conditioner under the low-temperature heating condition of the present invention.

[0065] like figure 1 As shown, in order to solve the problems of poor rapid...

Abstract

The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and system under the low-temperature heating work condition, and aims at solving the problems that an existing air conditioner is poor in rapid heating effect and lubricating effect. To achieve the purpose, the control method comprises the steps that the environment temperature is obtained; when the environment temperature is smaller than the set temperature, a compressor is preheated; after preheating is ended, an outer draught fan is started, and the speed is increased to thefirst target rotation speed; when the outer draught fan starts to accelerate or before the outer draught fan starts to accelerate or after the outer draught fan starts to accelerate, the aperture of an expansion valve is adjusted to the first target aperture; when the outer draught fan and/or the expansion valve reach/reaches the set conditions, the compressor is started; and the frequency of thecompressor is continuously increased in a staging manner according to multiple set speeds. According to the method, the compressor frequency increasing time can be greatly shortened, the purposes of rapid heating and improving lubrication are achieved, 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 conditioning, in particular to an air conditioning control method and system under low-temperature heating conditions. 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 heating and thus bring a more comfortable experience, the existing air conditioner generally makes the compressor quickly increase to a higher frequency when it is 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 ...
