Abstract

The invention relates to the technical field of air conditioning, in particular to an air conditioning control method and system under high-humidity heating conditions. The invention aims to solve the problems in the existing air conditioner start-up frequency increase control method that the rapid heating effect is poor due to the long frequency increase time, and the outdoor unit is easy to frost when the ambient humidity is high. For this purpose, the control method of the present invention includes: obtaining the ambient humidity; when the ambient humidity is greater than the set humidity, starting the external fan and raising the speed to the first target speed; Adjust the opening of the expansion valve to the first target opening; start the compressor when the external fan and the expansion valve reach the set conditions; make the compressor continuously increase in frequency in stages according to a plurality of frequency increasing speeds. The above setting method can greatly shorten the frequency increase time of the compressor while ensuring the normal oil return of the compressor, thereby achieving the purpose of rapid heating and delaying frosting, improving the comfort of the air conditioner and improving the user experience.

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 high-humidity 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 re...

Embodiment Construction

[0059] 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.

[0060] First refer to figure 1 , figure 1 It is a schematic flowchart of the control method of the air conditioner under the high-humidity heating condition of the present invention.

[0061] Such as figure 1 As shown, in order to solve the problems existing in ...
