Referring to fig. 2, in an embodiment, a control method of an air conditioner includes:

and step S20, controlling the air conditioner to execute the temperature return operation when the air conditioner meets the temperature return trigger threshold.

In this embodiment, in the cooling stage, the air conditioner may operate according to an operation parameter set by a user, for example, the air conditioner is controlled to operate for a preset time according to a preset parameter, or the air conditioner is controlled to operate according to a preset operation parameter and a temperature-return trigger threshold, such as a temperature threshold or a time threshold, is set, or the temperature-return trigger threshold is set, and a corresponding operation parameter is obtained according to a reference parameter (such as at least one of an environmental parameter and an operation parameter) and the temperature-return trigger threshold, and the operation is performed according to the operation parameter.

Similarly, the temperature return stage may operate according to an operation parameter set by a user, for example, the air conditioner is controlled to operate for a preset time according to a preset parameter, or the air conditioner is controlled to operate according to a preset operation parameter and a target temperature rise threshold, such as a temperature threshold or a time threshold, or the target temperature rise threshold is set, and a corresponding operation parameter is obtained according to a reference parameter (such as at least one of an environmental parameter and an operation parameter) and the target temperature rise threshold, and the operation is performed according to the operation parameter.

In the supercooling prevention mode, if the indoor temperature or the sensible temperature drops too low in the mode, the temperature return operation is performed; it is understood that the temperature returning operation may be performed if the temperature difference between the outdoor temperature and the indoor temperature is too large.

It can be understood that the cooling rate of the cooling phase may be greater than the heating rate of the heating phase to achieve rapid reduction of the indoor temperature, so that the user can feel the temperature drop obviously, and slowly raise the temperature back to the target heating threshold in the temperature-returning phase, so that the indoor environment is maintained at a lower temperature for a longer time, so that the user can feel cool indoors, and the user comfort is improved. For example, the compressor of the air conditioner is controlled to operate at a first frequency in the cooling stage, and the compressor of the air conditioner is controlled to operate at a second frequency in the heating operation stage, where the first frequency is greater than the second frequency, the frequency in the first stage may be the maximum frequency at which the air conditioner operates, and the frequency in the second stage may be a preset second frequency, or may be obtained by a target heating threshold. Alternatively, the first frequency and the second frequency may be preset by a user and stored in at least one of the air conditioner, the control device, and the server.

In the temperature return stage, the indoor temperature is adjusted to be a target temperature rise threshold value, the target temperature rise threshold value can be a temperature value set by a user, and the target temperature rise threshold value can also be obtained through big data analysis. It is understood that the room temperature at the beginning of the cool down phase is greater than the room temperature at the end of the warm up phase to make the user feel cool.

Because the wind speed and the humidity have influence on the sensible temperature of the user, the sensible temperature of the user can be adjusted by adjusting at least one of the wind speed and the humidity in a cooling stage and a temperature returning stage so as to make the feeling of the user more comfortable, and optionally at least one of a fan of the air conditioner and a fan linked with the air conditioner is controlled to operate at a first rotating speed in the cooling operation stage; and controlling at least one of a fan of the air conditioner and a fan linked with the air conditioner to operate at a second rotating speed in the temperature return operation stage, wherein the first rotating speed is greater than the second rotating speed. This indoor user's impression to the wind speed accessible adjusts the rotational speed of indoor fan or the rotational speed of indoor fan and realizes, and this indoor fan can link with the air conditioner. The humidity can also be adjusted in a linked manner in the cooling stage and the temperature returning stage, namely, the user can feel more comfortable through the temperature setting in the cooling stage and the temperature returning stage, if the humidity set in the temperature returning stage is smaller than the humidity set in the cooling stage, the lower the indoor humidity is, the higher the sensible temperature felt by the user is, under the same indoor temperature environment.

The supercooling prevention mode is used for reducing the indoor temperature of the air conditioner in a cooling-first and heating-second mode, and in the process, as the temperature return trigger threshold is smaller than the target heating threshold, the indoor temperature is firstly reduced to the temperature at which a user obviously feels cool, and then the indoor temperature is increased to the more comfortable and cool temperature.

In the cooling stage and when an operation parameter adjusting instruction is received, controlling the air conditioner to exit the cooling stage; or controlling the air conditioner to exit the temperature return stage when the temperature return stage receives the operation parameter adjusting instruction. It can be understood that the cooling stage and the temperature returning stage can also be exited when a shutdown instruction is received; or exiting the supercooling prevention mode upon receiving an exit command of the supercooling prevention mode.

In this embodiment, the temperature-return triggering threshold may be at least one of an indoor ambient temperature, a difference between an outdoor ambient temperature and an indoor ambient temperature, a user sensible temperature, and an operation duration, and when the temperature-return triggering threshold includes a plurality of parameters, when each parameter reaches the corresponding temperature-return triggering threshold, the temperature-return stage is directly entered; or setting a weight value corresponding to each parameter, obtaining a final value according to each weight value, and comparing the final value with a temperature return trigger threshold value according to the final value; it can be understood that a generation model of the back-temperature trigger threshold may also be set, and each parameter is input into the model to output the back-temperature trigger threshold, and the model may be generated in a big data manner, which is not described herein again.

The operating parameter, the sensible temperature and at least one of the environmental parameters satisfying the back-temperature triggering threshold may include that the operating parameter and/or the environmental parameter itself satisfies the back-temperature triggering threshold, and another parameter value obtained by the operating parameter and/or the environmental parameter satisfies the back-temperature triggering threshold, for example, a calculation formula of the sensible temperature may be:

Ts＝T₁+W₁×(H-H₀)

wherein Ts represents sensible temperature, T₁Is the indoor temperature, H is the indoor air humidity, W is the indoor fan speed of the air conditioner, H₀Is a standard humidity value, W₁Are coefficients. The sensible temperature can be obtained by calculating the indoor temperature and the indoor humidity, namely when the sensible temperature is greater than the preset sensible temperature, the environmental parameter is shown to meet the temperature return triggering threshold value. The operating parameter may include at least one of an indoor temperature, an indoor humidity, a temperature difference between an outdoor temperature and an indoor temperature; the operating parameter may include length of time of operation, it being understood that since the room temperature is related to the heat exchanger coil temperature, operation is dependent uponThe parameters may also include indoor heat exchanger coil temperature.

At least one of the operating parameter, the sensible temperature and the environmental parameter meeting a tempering trigger threshold value comprises at least one of:

reducing the indoor environment temperature to a first preset indoor environment temperature;

the difference between the outdoor environment temperature and the indoor environment temperature reaches a first preset difference;

the somatosensory temperature of the user is reduced to a first preset somatosensory temperature;

the running time of the cooling operation of the air conditioner reaches a first preset time.

The first preset indoor environment temperature can be 22-24 ℃, the first preset difference can be 4-6 ℃, and the first preset sensible temperature can be 10-30 min.

The temperature-return triggering threshold value can be a pre-stored temperature-reduction threshold value, the pre-stored temperature-reduction threshold value can be manually set by a user or can be obtained according to big data, the temperature-return triggering threshold value analyzed by the big data is stored, and when the temperature-return triggering threshold value is obtained, the stored temperature-return triggering threshold value is directly obtained; certainly, the stored temperature-return trigger threshold is continuously updated based on the continuous update of the big data; alternatively, the temperature-returning trigger threshold may be obtained after entering the anti-supercooling mode or the temperature-lowering phase.

The realization mode of the back temperature trigger threshold obtained by the big data can be as follows: the user groups corresponding to the users of the air conditioner are different, and the temperature return trigger thresholds are different. The user population is obtained by clustering user information including but not limited to gender, age, income, class, occupation and hobby. Specifically, cosine similarity between users is calculated according to user information to obtain a cosine similarity matrix, and a plurality of user groups are obtained by calculating the cosine similarity matrix according to a clustering algorithm.

Further, a temperature return trigger threshold value set by each user in the user group within a preset time interval is obtained, and the temperature return trigger threshold value with the set frequency meeting a preset frequency condition is used as the temperature return trigger threshold value. The preset frequency condition can be that the set frequency is maximum or the set frequency is greater than the preset frequency, when a plurality of temperature return trigger thresholds which are greater than the preset frequency are provided, the temperature return trigger thresholds can be stored, and a user selects a required temperature return trigger threshold; when the temperature-return triggering threshold value which is greater than the preset frequency is not available, sample data can be added, namely, big data analysis is carried out again by combining the temperature-reduction threshold value set by the user in the previous time interval. For example, when the user starts the supercooling prevention function, the temperature return trigger thresholds set by the users in the user group are inquired, and the temperature return trigger threshold with the set frequency meeting the preset frequency condition (for example, the set frequency is the highest) is selected as the temperature return trigger threshold. It should be noted that, if the data in the user group is insufficient, the data in the adjacent user group may be acquired for reference.

In this embodiment, when the air conditioner enters the supercooling prevention mode and the air conditioner meets the supercooling trigger threshold, the air conditioner is controlled to execute the supercooling operation, wherein the user groups corresponding to the users of the air conditioner are different, and the supercooling trigger thresholds are different, so that the air conditioner can accurately return the temperature in the cooling operation process, and the indoor environment is cool but not supercooled.

In one embodiment, the back-temperature trigger threshold is obtained based on at least one of location information and a user population. The location information may include at least one of a geographic area, a climate area, a city level, a province, a town, and a region, the geographic area may include a north part, a south part, an east part, a west part, a middle part, and the like, and each region may be further divided, such as a northeast part, a northwest part, and the like; the climate area can be divided into tropical zone, subtropical zone, temperate zone and other climate areas; the city grade can be a city in the direct jurisdiction, a first-line city, a second-line city and the like, and each parameter in the position information can be combined with a user group to determine the temperature return triggering threshold value.

The temperature-return triggering threshold is obtained by a first temperature-return triggering threshold and a second temperature-return triggering threshold, the first temperature-return triggering threshold is determined according to the user group, and the second temperature-return triggering threshold is determined according to the position information. Further, acquiring a temperature return trigger threshold set by each user in the user group within a preset time interval, and taking the temperature return trigger threshold with a set frequency meeting a preset frequency condition as a first temperature return trigger threshold; acquiring a temperature return trigger threshold currently set by an air conditioner in a target area corresponding to the position information, and taking the temperature return trigger threshold with the set frequency meeting a preset frequency condition as a second temperature return trigger threshold; and performing weighted calculation on the first and second temperature-return trigger thresholds, and determining the temperature-return trigger threshold according to the calculation result. The preset frequency condition can be that the set frequency is maximum or the set frequency is greater than the preset frequency, when a plurality of temperature return triggering thresholds which are greater than the preset frequency are provided, the temperature return triggering thresholds can be stored, and a user selects a required temperature return triggering threshold; when the temperature-return triggering threshold value which is greater than the preset frequency is not available, sample data can be added, namely, big data analysis is carried out again by combining the temperature-reduction threshold value set by the user in the previous time interval. For example, when a user starts a supercooling prevention function, a temperature return trigger threshold value set by each user in a user group is inquired, and the temperature return trigger threshold value with a set frequency meeting a preset frequency condition is selected as a first temperature return trigger threshold value; inquiring a currently set temperature return trigger threshold value of air conditioners (or a preset number of air conditioners closest to the air conditioners) within a preset distance from the air conditioners, and selecting the temperature return trigger threshold value with a set frequency meeting a preset frequency condition as a second temperature return trigger threshold value; and the first and second temperature-return trigger thresholds have different weights, the first and second temperature-return trigger thresholds are weighted and calculated, and the temperature-return trigger thresholds are determined according to the calculation result.

It should be noted that the temperature return trigger threshold may also be obtained according to a temperature return trigger threshold currently set by the air conditioner in the target area corresponding to the location information, where the temperature return trigger threshold is a temperature return trigger threshold whose set frequency meets a preset frequency condition. For example, when the user starts the supercooling prevention function, the temperature return trigger thresholds set by the air conditioners within a preset distance from the air conditioners (or a preset number of air conditioners closest to the air conditioners) are inquired, and the temperature return trigger threshold with the set frequency meeting the preset frequency condition is selected as the temperature return trigger threshold.

In the embodiment, the temperature return triggering threshold value is determined by combining the user group and the position information, so that the air conditioner can accurately return the temperature in the cooling operation process, and the indoor environment is cool without being too cold.

The user population is obtained by clustering user information including but not limited to gender, age, income, class, occupation and hobby. Specifically, cosine similarity between users is calculated according to user information to obtain a cosine similarity matrix, and a plurality of user groups are obtained by calculating the cosine similarity matrix according to a clustering algorithm.

Further, a target temperature-raising threshold set by each user in the user group within a preset time interval is obtained, and the target temperature-raising threshold with the set frequency meeting a preset frequency condition is used as the target temperature-raising threshold. The preset frequency condition can be that the set frequency is maximum or the set frequency is greater than the preset frequency, when a plurality of target temperature rise thresholds which are greater than the preset frequency are provided, the target temperature rise thresholds can be stored, and a user selects a required target temperature rise threshold; when the target temperature-rise threshold value larger than the preset frequency is not available, sample data can be added, namely big data analysis is carried out again by combining the temperature-fall threshold value set by the user in the previous time interval. For example, when the user starts the supercooling prevention function, the target temperature increase threshold set by each user in the user group is queried, and the target temperature increase threshold whose set frequency meets a preset frequency condition (for example, the set frequency is the highest) is selected as the target temperature increase threshold. It should be noted that, if the data in the user group is insufficient, the data in the adjacent user group may be acquired for reference.

In this embodiment, when the air conditioner enters the supercooling prevention mode and the air conditioner meets the target heating threshold, the air conditioner is controlled to perform a temperature return operation, wherein the user groups corresponding to the users of the air conditioner are different, and the target heating threshold is different, so that the air conditioner is accurately heated in the cooling operation process, and the indoor environment is cool but not supercooled.

Further, a target temperature-rising threshold value set by each user in the user group within a preset time interval is obtained, and the target temperature-rising threshold value with the set frequency meeting a preset frequency condition is used as a first target temperature-rising threshold value; acquiring a target temperature-rising threshold value currently set by the air conditioner in a target area corresponding to the position information, and taking the target temperature-rising threshold value with the set frequency meeting a preset frequency condition as a second target temperature-rising threshold value; and performing weighted calculation on the first target temperature-rising threshold and the second target temperature-rising threshold, and determining the target temperature-rising threshold according to the calculation result. The preset frequency condition can be that the set frequency is maximum or the set frequency is greater than the preset frequency, when a plurality of target temperature rise thresholds which are greater than the preset frequency are provided, the target temperature rise thresholds can be stored, and a user selects a required target temperature rise threshold; when the target temperature rise threshold value which is larger than the preset frequency is not available, sample data can be increased, namely, big data analysis is carried out again by combining the temperature fall threshold value set by the user in the previous time interval. For example, when a user starts a supercooling prevention function, a target temperature rise threshold set by each user in a user group is inquired, and a target temperature rise threshold with a set frequency meeting a preset frequency condition is selected as a first target temperature rise threshold; inquiring a target temperature-rising threshold value currently set by air conditioners (or a preset number of air conditioners closest to the air conditioners) within a preset distance from the air conditioners, and selecting the target temperature-rising threshold value with a set frequency meeting a preset frequency condition as a second target temperature-rising threshold value; and the first target temperature-rising threshold and the second target temperature-rising threshold are respectively different in weight, the first target temperature-rising threshold and the second target temperature-rising threshold are subjected to weighted calculation, and the target temperature-rising threshold is determined according to the calculation result.

For example, when the user starts the supercooling prevention function, the target temperature increase threshold set by the air conditioners within a preset distance from the air conditioners (or a preset number of air conditioners closest to the air conditioners) is queried, and the target temperature increase threshold whose set frequency meets a preset frequency condition is selected as the target temperature increase threshold.
