Embodiment Construction

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 As shown, an intelligent high-frequency start-up control method for an inverter air conditioner unit includes:

[0020] Step S110, obtaining a setting instruction, and setting a non-high-frequency start-up time period. When starting up for the first time, set the non-high-frequency start-up time period. When the user can set multiple non-high-frequency start-up time periods according to needs, it can include: 18:00 to 20:00 and / or 24:00 to 8:00, as shown in the table below.

Abstract

The invention discloses a variable frequency air conditioner and an intelligent unit high-frequency starting control method and system of the variable frequency air conditioner. The method comprises the step of obtaining a set order and a non-high-frequency starting quantum, the step of obtaining a starting order and judging whether the starting time is in the non-high-frequency starting quantum or not, the step of driving a compressor to be soft started in a low-frequency mode if the starting time is in the non-high-frequency starting quantum, and the step of driving the compressor to be started in a high-frequency mode if the starting time is not in the non-high-frequency starting quantum. The variable frequency compressor started in the high-frequency mode is controlled in a day parting mode at the starting stage so that the impact of an excessively large starting current to a community and urban power grid at the power utilization rush hours and the centralized starting-up time quantum can be reduced, the trip frequency is reduced, and meanwhile the problem that the high-frequency starting noise disturbs residents at the rest time quantum is avoided.

Description

technical field [0001] The invention belongs to air-conditioning equipment, in particular to an intelligent high-frequency start-up control method and system for an inverter air conditioner and its unit. Background technique [0002] At present, in order to speed up the cooling and heating speed of inverter air conditioners, most air conditioner manufacturers use high-frequency start-up during the start-up phase. High-frequency start-up will inevitably bring about the problem of excessive start-up current. During the peak period of power consumption, users concentrate on starting up at the same time, and the air conditioner uses high-frequency start-up. Excessive current trip. In addition, when there is an abnormal shutdown, everyone starts up at the same time, which is likely to cause secondary tripping. [0003] Moreover, although high-frequency starting can achieve the effect of rapid cooling and cooling, high-frequency starting also has the problem of high noise during...
