Embodiment 1

[0052] figure 1 is the flow chart of the air-conditioning control method provided by the first embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0053] S101 , after the air conditioner is started, the operation of the air conditioner is controlled according to a first control mode.

[0054] S102, when it is detected that the absolute value of the difference between the indoor ambient temperature and the set temperature changes from greater than a preset threshold to less than or equal to a preset threshold, or when the duration of executing the first control mode reaches a first preset time, Enter the second control mode. In the second control mode, the specified operating parameters of the air conditioner are adjusted according to the preset energy efficiency model, so that the indoor ambient temperature reaches the set temperature and the energy efficiency of the air conditioner is greater than the reference energy ef...

Embodiment 2

[0096] The above air-conditioning control method will be described below with reference to a specific embodiment. However, it should be noted that this specific embodiment is only for better description of the present application, and does not constitute an improper limitation of the present application. Terms that are the same as or corresponding to the above-mentioned embodiments are explained, and are not repeated in this embodiment.

[0097] First, an energy efficiency model needs to be established to be used in the control chip of the air conditioner. Specifically, the operating data of the air conditioner under various typical operating conditions is tested, the data obtained by the test is preprocessed, and the non-steady data and outliers are eliminated to obtain a data set. Then feature extraction is performed on the dataset through thermodynamic analysis and expert knowledge, and relevant variables that may be beneficial for modeling are selected, and useful variable...

Embodiment 3

[0138] Based on the same inventive concept, this embodiment provides an air conditioner control device, which can be used to implement the air conditioner control method described in the foregoing embodiments. The device can be implemented by software and / or hardware, and the device can generally be integrated in the controller of the air conditioner.

[0139] Figure 4 is the structural block diagram of the air-conditioning control device provided by the third embodiment of the present invention, such as Figure 4 As shown, the device includes:

[0140] The first control module 41 is used to control the operation of the air conditioner according to the first control mode after the air conditioner is started;

[0141] The second control module 42 is configured to detect that the absolute value of the difference between the indoor ambient temperature and the set temperature changes from greater than a preset threshold to less than or equal to the preset threshold, or when the...

Abstract

The invention discloses an air conditioner control method, device and air conditioner. The method includes: after the air conditioner is started, controlling the operation of the air conditioner according to the first control mode; when it is detected that the absolute value of the difference between the indoor ambient temperature and the set temperature changes from greater than a preset threshold to less than or equal to the preset threshold, Or when the duration of executing the first control mode reaches the first preset time, enter the second control mode, and in the second control mode, adjust the specified operating parameters of the air conditioner according to the preset energy efficiency model, so that the indoor ambient temperature reaches the preset value The temperature and the energy efficiency of the air conditioner are greater than the reference energy efficiency in the first control mode. Through the second control mode, the present invention can automatically adjust the value of the specified operating parameters in combination with the actual working conditions of the air conditioner, and realize the dual-objective adaptive energy-saving control of energy efficiency and temperature, so that the air conditioner can ensure the energy-saving effect while controlling the indoor ambient temperature, and realize the full scene. It can run efficiently under the conditions and can greatly reduce the amount of parameter development experiments.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to an air conditioner control method and device, and an air conditioner. Background technique [0002] At present, the factory control parameters of air conditioners (such as multi-connection, etc.) are optimized and calibrated under the combination of standard connecting pipes, drop and indoor units. However, in actual projects, the usage scenarios of air conditioners are complex, with different connecting pipes and drops. The form is uncertain. As a result, the initial factory control logic of the air conditioner does not completely match the actual situation of the user, and it is difficult for the air conditioner to operate efficiently in all scenarios. [0003] The parameters of the existing control algorithm are debugged in a single laboratory and have poor adaptability to the complex and changeable installation environment. When the air conditioner is ...
