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 ...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method and system for air conditioner under a high-humidity heating working condition. In order to solve the problems that a start-up frequency boosting control method for an existing air conditioner is poor in quick heating effect as a result of long frequency boosting time and an outdoor unit is liable to frost when environmental humidity is relatively great, the control method comprises the following steps: obtaining ambient humidity; starting up an outer fan when the ambient humidity is greater than set humidity; increasing speed to first target rotation speed; regulating opening degree of an expansion valve to first target opening degree while or before or after the outer fan starts to increase speed; starting a compressor when the outer fan and/or the expansion valve reaches a set condition; and enabling the compressor to continuously boost frequency in stages according to multiple set speeds. In this way, frequency boosting time of the compressor can be greatly shortened while the compressor can be guaranteed to normally return oil, so that the purposes of quickly heating and delaying frosting are achieved, and therefore, 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 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...
