Referring to fig. 2, an embodiment of the present invention provides an air conditioner control method, including:
step S10, detecting the current indoor environment temperature and the outdoor environment temperature;
the current indoor environment temperature can be obtained by detecting the return air temperature of the indoor unit of the air conditioner, for example, a temperature sensor is arranged at the return air inlet of the indoor unit of the air conditioner for detection; or, the indoor environment temperature may also be detected by a temperature sensor provided in another device in the indoor environment where the air conditioner is located, for example, a temperature sensor on a wearable device (e.g., a bracelet) worn by the user detects the indoor environment temperature, and the temperature detected by the wearable device is the ambient temperature of the user, which is more accurate.
The current outdoor environment temperature can be obtained by detecting the environment temperature of the outdoor unit of the air conditioner, for example, a temperature sensor is arranged at an air outlet of the outdoor unit of the air conditioner for detection; alternatively, the outdoor ambient temperature may be obtained by obtaining a local monitored temperature of a region where the air conditioner is located, for example, the air conditioner is connected to a local weather system or a real-time weather application in a mobile phone, and the local real-time temperature monitored in the system or the application is used as the current outdoor ambient temperature.
Step S20, judging whether the indoor environment temperature is larger than the preset temperature;
the indoor environment temperature and the preset temperature are judged, the preset temperature can be the target temperature when the compressor operates to adjust the indoor environment temperature, the preset temperature can be set according to the requirements of users, the target temperature set by the users at present for the air conditioner can be obtained by obtaining the target temperature, and the set temperature value determined by considering conditions such as the use condition of most users and the energy consumption condition of the compressor can be also considered for designers. The preset temperature may be selected to be 26 ℃ to meet the comfort requirements of most users. When the indoor environment temperature is greater than the preset temperature, the following steps S30, S40 are sequentially performed; when the indoor ambient temperature is less than or equal to the preset temperature value, the following step S50 is performed.
Step S30, determining the energy-saving frequency of the compressor of the air conditioner according to the indoor environment temperature and the outdoor environment temperature;
when the indoor ambient temperature is greater than the preset temperature, the compressor needs to operate to achieve a reduction in the indoor ambient temperature. In order to reduce the energy consumption of the air conditioner, a mapping relationship between different ambient temperatures and the energy saving frequency of the compressor of the air conditioner may be established in advance, in which one indoor ambient temperature and one outdoor ambient temperature correspond to one energy saving frequency. The corresponding energy-saving frequency can be a specific numerical value, and can also be a calculation mode of the energy-saving frequency and the like. The energy-saving frequency is lower than the current running frequency of the compressor, is determined based on the indoor environment temperature and the outdoor environment temperature, and can meet the temperature drop requirement of the indoor environment under the corresponding environment temperature working condition so as to ensure the comfort of users. The mapping relation can be determined by methods such as massive data fitting, empirical values, computer simulation and the like, and is particularly suitable for different temperature drop requirements, heat exchange efficiencies of different air conditioners, different use requirements of users and the like. Specifically, the expression form of the mapping relationship may be a table, a chart, a formula, and the like. According to the detected environment temperature, the energy-saving frequency corresponding to the environment temperature can be determined through the mapping relation.
In addition, under the same working condition, the mapping relation between the same environment temperature and the energy-saving frequency can be different according to different setting parameters of a user, for example, different wind speed gears of the air conditioner can correspond to different mapping relations, different energy-saving frequencies can be obtained according to different wind speed gears selected by the user, and the air conditioner can meet the comfort of the user and simultaneously realize the reduction of energy consumption.
And step S40, controlling the compressor to operate according to the energy-saving frequency so as to reduce the energy consumption of the air conditioner.
And step S50, controlling the compressor to stop running.
When the indoor environment temperature is less than or equal to the preset temperature, the current indoor environment temperature can be considered to meet the use requirement of a user, cooling operation is not needed, and the compressor can be controlled to stop running. The lowest energy consumption of the compressor can be realized at this time. In addition, the compressor can be controlled to keep running at a lower frequency value, the indoor environment temperature can be stabilized, and the user comfort is ensured.
The current indoor ambient temperature and the current outdoor ambient temperature can be obtained in real time or in a timing mode. The current indoor and outdoor temperature values are obtained in real time, the energy-saving frequency is determined according to the current indoor and outdoor temperature values, and the compressor can be kept in a low energy consumption state all the time; the current indoor and outdoor temperature values are obtained regularly, the energy-saving frequency is determined according to the current indoor and outdoor temperature values, and the energy consumption of the compressor can be reduced to a certain extent. In addition, the current indoor and outdoor temperature values can be obtained only when an energy-saving instruction is received, and the energy-saving frequency is determined according to the current indoor and outdoor temperature values, wherein the energy-saving instruction can be sent by a user, so that the compressor can reduce the energy consumption when the user needs the compressor.
In this embodiment, through detecting current indoor ambient temperature and outdoor ambient temperature, judge whether indoor ambient temperature is greater than preset temperature, preset temperature sets for according to the user's demand, when indoor ambient temperature is greater than preset temperature, need the compressor operation to make indoor ambient temperature reach the preset temperature of user's demand, confirm energy-conserving frequency according to indoor ambient temperature and outdoor ambient temperature, control compressor operates according to energy-conserving frequency, in order to reduce the energy consumption of air conditioner, energy-conserving frequency is little and can guarantee the temperature drop requirement of indoor environment compared with the current operating frequency of compressor under the same operating mode, therefore make the air conditioner can realize the reduction of air conditioner energy consumption when satisfying user's travelling comfort under the same operating mode.
Referring to fig. 3, a second embodiment of the present invention is proposed based on the first embodiment, and in this embodiment, step S30 of the first embodiment specifically includes the following steps:
and step S31, calculating the energy-saving frequency through a preset formula according to the indoor environment temperature and the outdoor environment temperature.
The mapping relationship between the indoor ambient temperature and the outdoor ambient temperature and the energy saving frequency in the first embodiment may be specifically established in a formula manner. Specifically, the preset formula is obtained by fitting a large number of indoor environment temperature values, outdoor environment temperature values and energy-saving frequencies capable of meeting the temperature drop requirements of corresponding working conditions through a computer, the preset formula can have multiple forms, and F can be specifically equal to a + bT1+cT4、F＝a+bT1 2+cT4 2、F＝bT1+cT4 2、F＝a*(bT1+cT4)、F＝a+bT1T4And the fitting method can be determined according to the fitting effect, the fitting mode and the use requirement, wherein F is the energy-saving frequency, a is a fixed parameter, b and c are respectively an adjusting parameter, T1Is the indoor ambient temperature, T4Is the outdoor ambient temperature. During fitting, the fixed parameter a can select the values of the air conditioner operation parameters such as the current frequency, the highest frequency and the like of the compressor, and a preset formula is determined by taking the fixed parameter a as a fixed quantity and determining the values of the adjustment parameters b and c according to the known indoor environment temperature, the known outdoor environment temperature and the energy-saving frequency so as to reduce the frequency of the compressor; and the numerical values of a, b and c can be directly obtained by directly fitting the known indoor environment temperature, the known outdoor environment temperature and the known energy-saving frequency to obtain a preset formula.
Specifically, the preset formula may be set to F ═ a + bT1+cT4Wherein the fixed parameter a has a value range of [ -172, -152 [ -172 [ ]](ii) a The value range of the adjusting parameter b is [3.14, 5.14]](ii) a The value range of the adjusting parameter c is [1.4, 2.4]]. When the adjustment parameters a, b and c are in the value ranges, the energy consumption of the air conditioner can be effectively reduced, and the comfort requirement of a user can be met. Preferably, in the above rangeLet F be-162 +4.14T1+1.90T4And when the compressor runs according to the energy-saving frequency determined by the preset formula, the energy efficiency ratio of the air conditioner can be the highest. Specifically, step S31 includes the steps of:

step S312, calculating the energy saving frequency according to the frequency adjustment variable and the fixed parameter by a preset formula.
In the preset formula, the indoor ambient temperature and the outdoor ambient temperature and the adjustment parameters thereof constitute frequency adjustment variables, such as bT in the above formula1+cT4、bT1 2+cT4 2、bT1+cT4 2、bT1T4And the like. After the frequency adjusting variable is calculated according to the detected indoor environment temperature and the outdoor environment temperature through a preset formula, the energy-saving frequency can be calculated according to the calculation relation between the frequency adjusting variable and the fixed parameter in the formula, wherein the calculation relation can be addition, subtraction, multiplication, division and the like, and is specifically determined according to the setting of the preset formula.
According to the control method of the air conditioner, after the indoor environment temperature and the outdoor environment temperature are detected, the corresponding energy-saving frequency is obtained through calculation of the preset formula, so that the energy-saving frequency corresponding to the indoor environment temperature and the outdoor environment temperature can be obtained no matter the indoor environment temperature and the outdoor environment temperature are at any temperature, and different working conditions can be adapted.
Referring to fig. 4, a third embodiment of the present invention is proposed based on the first embodiment, and in this embodiment, step S30 of the above embodiment specifically includes the following steps:
and step S32, according to the indoor environment temperature and the outdoor environment temperature, inquiring the energy-saving frequency corresponding to the temperature and energy-saving frequency comparison table matched with the compressor of the air conditioner.
The mapping relationship between the indoor ambient temperature and the outdoor ambient temperature and the energy saving frequency in the first embodiment may be established in a table manner, for example, a comparison table of the temperature and the energy saving frequency is established. The temperature and energy-saving frequency comparison table in this embodiment includes the indoorThe system comprises an environment temperature, an outdoor environment temperature and energy-saving frequencies, wherein each indoor environment temperature and each outdoor environment temperature correspond to one energy-saving frequency. The comparison table of temperature and energy-saving frequency is shown in the following table 1, and the first row of data in table 1 is outdoor environment temperature T4There are M; the first column of data in Table 1 is the indoor ambient temperature T1N data values are provided, and the data values are all larger than the preset temperature so as to ensure the applicability of the table; the data of each indoor environment temperature and outdoor environment temperature crossing and corresponding in the table is energy-saving frequency F, and there are M N. M, N are all natural numbers greater than or equal to 1, and in order to adapt to more working conditions, the values of M or N can be set as much as possible, as shown in table 1, the value of M is 8, the value of N is 6, the corresponding energy-saving frequencies are 48, and all data are integers. In the table, the difference between the adjacent ambient temperatures may be set to be the same, and the smaller the difference, the more adaptive the operating condition is, as in table 1, the difference between the adjacent indoor ambient temperatures is relatively 1 ℃, and the difference between the adjacent outdoor ambient temperatures is equal and 2 ℃. In the comparison table of temperature and energy-saving frequency, when the outdoor environment temperature is greater than or equal to a certain value (such as 30 ℃ in table 1), the energy-saving frequency tends to increase along with the increase of the indoor environment temperature, and when the outdoor environment temperature is less than the certain value, the energy-saving frequency does not change along with the change of the indoor environment temperature; when the indoor temperature is higher than or equal to a certain value (such as 28 ℃ in table 1), the energy-saving frequency tends to increase along with the increase of the outdoor environment temperature value, and when the indoor environment temperature is lower than the certain value, the energy-saving frequency does not change along with the change of the indoor environment temperature, so that the reduction of the energy consumption of the air conditioner can be realized while the comfort of a user is ensured.

For example, when the detected indoor ambient temperature is 31.4 ℃ and the detected outdoor ambient temperature is 34 ℃, the outdoor ambient temperature can find a corresponding temperature value in table 1, and processing is not required, the indoor ambient temperature does not have a corresponding temperature value in table 1, a temperature value with the minimum difference with the indoor ambient temperature of 31 ℃ can be found in table 1 by a rounding method, and then 31 ℃ is approximate indoor ambient temperature, and the energy-saving frequency can be determined to be 30HZ by the approximate indoor ambient temperature of 31 ℃ and the outdoor ambient temperature of 34 ℃; when the detected indoor environment temperature is 31 ℃ and the detected outdoor environment temperature is 34.9 ℃, the indoor environment temperature can find a corresponding temperature value in the table 1, processing is not needed, the outdoor environment temperature has no corresponding data in the table 1, the temperature interval in which the outdoor environment temperature 34.9 ℃ is located in the table 1 can be determined to be [34,36], the 34 ℃ is approximate to the outdoor environment temperature by respectively differentiating the end values 34 ℃ and 36 ℃ of the interval of 34.9 ℃, and according to a minimum difference value method, the 34 ℃ is the data with the minimum difference value with the current outdoor environment temperature, and the energy-saving frequency can be determined to be 30HZ by the indoor environment temperature being 31 ℃ and the approximate to the outdoor environment temperature being 34 ℃.
Besides the above method, the approximate temperature value may also be determined by setting different rules according to the needs of the user, and is not specifically limited herein.
In addition, in addition to determining the approximate temperature value, when the detected indoor ambient temperature and outdoor ambient temperature do not have corresponding temperature values in the temperature-to-saving frequency comparison table, the air conditioner may not respond and the compressor is operated at the current frequency.

step S325, if not, calculating the energy-saving frequency through a preset formula according to the indoor environment temperature and the outdoor environment temperature.
When the detected indoor environment temperature and the outdoor environment temperature have no corresponding data in the temperature and energy-saving frequency comparison table, the mapping relation between the indoor environment temperature and the outdoor environment temperature and the energy-saving frequency can be established by presetting a preset formula, so that when the detected indoor environment temperature and the detected outdoor environment temperature cannot be matched with the corresponding energy-saving frequency in the temperature and energy-saving frequency comparison table, the energy-saving frequency corresponding to the detected indoor environment temperature and the detected outdoor environment temperature can be calculated by the preset formula, and the energy-saving frequency can be adapted to more working conditions.
The preset formula may be various, and specifically, the form, the obtaining method, and the like of the preset formula may be consistent with the preset formula in the second embodiment, which is not described herein again. In addition, the preset formula of the embodiment may have other forms according to actual needs.
