Fig. 1 is a flowchart illustrating a control method of an air conditioning apparatus according to an embodiment of the present invention.
As shown in fig. 1, the method comprises the steps of:
The heat source is an object in the current environment, such as a human body, a teapot and the like, and is obtained by detecting environmental parameters, as a possible implementation manner, parameters obtained by detecting the air conditioning equipment are detected through the air conditioning equipment, for example, the environmental temperature distribution obtained by detecting an array type infrared thermopile sensor of the air conditioning equipment, and the cold and heat sensing values of the heat source are determined according to the environmental temperature distribution and the operation mode of the air conditioning equipment; as another possible implementation manner, the cold and hot sensing values of the heat source may also be determined according to parameters detected by the air conditioning device itself, in combination with parameters such as humidity detected by other air devices, for example, a humidifier or a dehumidifier. The magnitude of the cold and hot feeling value reflects the cold and hot degree of the heat source, that is, the larger the cold and hot feeling value is, the higher the temperature of the heat source is, that is, the hotter the heat source is, and the smaller the cold and hot feeling value is, the lower the temperature of the heat source is, that is, the colder the heat source is. In one scenario, when the heat source is the user, the heat and cold feeling value of the user is related to the personal physique and the exercise intensity of the user, in actual operation, real-time collection and labeling can be performed according to the personal condition of the user, or a model of the user body surface reference temperature and the user heat and cold feeling value can be established according to big data (in this example, a large number of hardware parameters such as the user heat and cold feeling value, the user body surface temperature, the area of an air deflector of the air conditioning equipment, the performance of a motor and the like are collected, a model of the user body surface reference temperature and the user heat and cold feeling value is established according to a large number of collected experimental data, as a possible implementation manner, the heat and cold feeling model can also be combined with a plurality of user physiological parameter settings and the like, wherein the expression formula of the heat and cold feeling model can be M ═ f (H), wherein M is the heat and cold feeling model, H ═ R + C + K + Esk, wherein, R is the heat generated by human body radiation and has the unit of W/m2, C is the heat generated by the convection of the air current in the human body and the environment and has the unit of W/m2, K is the heat dissipation generated by conduction, has the unit of W/m2, Esk is the heat dissipation generated by the evaporation of the moisture of the skin and has the unit of W/m2, Eres is the heat dissipation generated by the evaporation of the moisture of the expiration, and has the unit of W/m2Cres is the heat dissipation flow generated by the convection of the expiration and has the unit of W/m 2).
It should be noted that the expression formula of the thermal sensation model described in this embodiment is only an example, and those skilled in the art can select an appropriate thermal sensation model according to the actual situation, for example, by increasing or decreasing the parameters in the expression formula of the thermal sensation model to meet the needs of the actual situation, and thus the details are not repeated here.
And 102, determining the operating parameters of the air conditioning equipment according to the cold and heat induction values.
Wherein the operating parameters comprise a set temperature and/or a wind speed.
In one possible implementation, when there are a plurality of heat sources, the maximum cooling/heating sensation value among the cooling/heating sensation values of the plurality of heat sources is used as the detected cooling/heating sensation value.

Wherein the ambient temperature information includes a background area temperature in a space where the air conditioning apparatus is located, the background area temperature being other than the heat source area. Under the operation modes of heating and refrigerating, the compensation value corresponding to the background area temperature is in an inverse relation with the background area temperature; under a refrigeration operation mode, a compensation coefficient corresponding to the background area temperature and the background area temperature are in a positive relation, and the value of the compensation coefficient is less than or equal to 1; in the heating operation mode, the compensation coefficient corresponding to the background area temperature is in an inverse relation with the background area temperature, and the value of the compensation coefficient is less than or equal to 1.
It should be noted that the forward relationship and the reverse relationship in the embodiment of the present invention may be a fixed proportion or a fixed value of the forward or reverse relationship, or a non-fixed proportion or a non-fixed value of the forward or reverse relationship, for example, in the heating operation mode, the ambient temperature of the background region and the compensation value are in a reverse relationship, that is, the ambient temperature of the background region increases, and the corresponding compensation value decreases, as a possible implementation manner, the smaller of the compensation value may decrease with the increase of the ambient temperature of the background region in a manner of decreasing by a fixed proportion or a fixed value, for example, in the heating mode, when the ambient temperature of the background region is 23 degrees celsius, the compensation value is-0.5, and when the ambient temperature of the background region is 25 degrees celsius, the compensation value is-1, and when the ambient temperature of the background region is 26 degrees celsius, the offset is-1.5, i.e., the offset decreases with a fixed decrease of 0.5 as the ambient temperature of the background area increases. As another possible implementation manner, the decrease of the compensation value may also decrease with the increase of the ambient temperature of the background area in a non-fixed proportion or in a non-fixed value increasing manner, for example, when the ambient temperature of the background area is 23 degrees celsius, the compensation value is-0.5, and when the ambient temperature of the background area is 25 degrees celsius, the compensation value is-1, and when the ambient temperature of the background area is 26 degrees celsius, the compensation value is-1.3, that is, the decrease of the compensation value decreases with the increase of the ambient temperature of the background area in a non-fixed proportion or in a non-fixed value decreasing manner. In addition, the principle of the forward relationship in this embodiment is similar, and the description thereof is omitted.
And 104, controlling the operation of the air conditioning equipment according to the corrected operation parameters.
Specifically, according to the corrected operation parameters, the swing speed of an air guide strip of the air conditioning equipment is reduced, or according to the corrected operation parameters, the air supply speed of the air conditioning equipment is reduced, or according to the corrected operation parameters, the set temperature of the air conditioning equipment is reduced in a heating operation mode, the set temperature of the air conditioning equipment is increased in a cooling operation mode, the accuracy of automatic control of the air conditioning equipment is improved, and comfortable experience is brought to a user.
In the embodiment of the application, the operation of the air conditioning equipment is controlled through the corrected operation parameters, the environment can be adjusted by controlling the refrigerating capacity or the heating capacity of the air conditioning equipment, and the refrigerating capacity or the heating capacity can be adjusted through the air supply capacity.
For example, when the air conditioning device is an air conditioner, the cooling capacity or the heating capacity of the air conditioning device may be determined by the following equation:
Q0＝(iC-iD)·G(kJ/h)；(1)
wherein Q is0To representRefrigerating capacity or heating capacity, iCAnd iDThe enthalpy values of the air before and after the evaporator are shown, and G represents the air blowing amount. i.e. iCAnd iDThe adjustment can be made by increasing or decreasing the power of the compressor.
Therefore, when it is determined that the cooling capacity or the heating capacity of the air conditioning equipment at the corresponding air supply angle needs to be increased according to the ambient temperature distribution, the air conditioning equipment can be controlled by the control unit at (i)C-iD) Under the condition that the value is kept unchanged, the cooling capacity or the heating capacity of the air conditioning equipment is increased by increasing the air supply capacity G. And when the cooling capacity or the heating capacity of the air conditioning equipment at the corresponding air supply angle needs to be reduced according to the environmental temperature distribution, the air conditioning equipment can be controlled by the control method in (i)C-iD) The cooling capacity or the heating capacity of the air conditioning equipment is reduced by reducing the air supply amount G under the condition that the value is kept unchanged.
In order to realize the adjustment of the air supply quantity, various control means such as the adjustment of the air speed, the adjustment of the swing speed of the air guide strip, the pause swing time and the like can be specifically adopted, and the control means can be combined to improve the adjustment efficiency of the refrigerating capacity or the heating capacity. Several possible implementations will be separately described below.

The maximum value in the temperature difference values of the air supply positions is larger, when the air guide strip of the air conditioning equipment swings to the corresponding air supply angle, the time length of pause swing of the air guide strip is larger, so that the refrigerating capacity or the heating capacity corresponding to the air supply angle is larger, the maximum value in the temperature difference values of the air supply positions is smaller, when the air guide strip of the air conditioning equipment swings to the corresponding air supply angle, the time length of pause swing of the air guide strip is smaller, and the refrigerating capacity or the heating capacity corresponding to the air supply angle is smaller.
As a fourth possible implementation manner, when the air guide bar of the air conditioning equipment swings to each air supply angle, the air speed of the supplied air and the swing speed of the air guide bar are adjusted according to the corresponding control parameters. The maximum value in the temperature difference value of the air supply position is larger, when the air guide strip of the air conditioning equipment swings to the corresponding air supply angle, the larger the air speed of the corresponding air supply is, and the smaller the swing speed of the air guide strip is, so that the refrigerating capacity or the heating capacity corresponding to the air supply angle is larger, and the smaller the maximum value in the temperature difference value of the air supply position is, when the air guide strip of the air conditioning equipment swings to the corresponding air supply angle, the smaller the air speed of the corresponding air supply is, the larger the swing speed of the air guide strip is, so that the refrigerating capacity or the heating capacity corresponding to the air supply angle is smaller.
As a fifth possible implementation manner, when the air guide bar of the air conditioning device swings to each air supply angle, the air speed of the supplied air and the pause swing time of the air guide bar are adjusted according to the corresponding control parameters. The maximum value in the temperature difference value of the air supply position is larger, when the air guide strip of the air conditioning equipment swings to the corresponding air supply angle, the wind speed of the corresponding air supply is larger, the time length of the pause swing of the air guide strip is larger, the refrigerating capacity or the heating capacity corresponding to the air supply angle is larger, the maximum value in the temperature difference value of the air supply position is smaller, when the air guide strip of the air conditioning equipment swings to the corresponding air supply angle, the wind speed of the corresponding air supply is smaller, the time length of the pause swing of the air guide strip is smaller, and the refrigerating capacity or the heating capacity corresponding to the air supply angle is smaller.

Based on the previous embodiment, this embodiment provides another control method for an air conditioning device, and fig. 2 is a schematic flow chart of the control method for another air conditioning device provided by the embodiment of the present invention.
As shown in fig. 2, the method may include the steps of:
In this embodiment, an air conditioning device is taken as an air conditioner, an air conditioner operation mode is taken as an example for explanation, fig. 3 is a schematic diagram of an ambient temperature distribution before correction according to an embodiment of the present invention, and since an object always radiates infrared energy outwards, when the air conditioner is in a refrigeration mode, the environment is detected by the array type infrared thermopile sensor, and temperature distributions of different corresponding objects in the ambient temperature distribution diagram are obtained by detection, as shown in fig. 3. And identifying the region with higher temperature in the temperature distribution diagram as a heat source region, namely, the regions marked with letters M1, M2, M3 and M4 in the diagram of FIG. 3, determining the temperature of the heat source according to the heat source region, and determining the corresponding cold and hot feeling values according to the temperature values of the heat sources M1-M4 by adopting the method in the step 101.
Alternatively, when there are a plurality of heat sources, the maximum cooling and heating sensation value among the cooling and heating sensation values of the plurality of heat sources is used as the detected cooling and heating sensation value, for example, in fig. 3, the cooling and heating sensation value corresponding to M4 is the maximum cooling and heating sensation value, that is, the cooling and heating sensation value corresponding to M4 is used as the detected cooling and heating sensation value.
And step 202, determining the operating parameters of the air conditioning equipment according to the cold and heat induction values.
Specifically, reference may be made to step 102 in the previous embodiment, which has the same principle and is not described herein again.
In the embodiment of the present invention, the initial value of the set temperature among the operation parameters of the air conditioning equipment is set to TSet, and the initial value of the operation wind speed is set to V.
Wherein, the environmental temperature distribution is detected by the array infrared thermopile sensor.
Specifically, the temperature of the region other than the heat source region in the environment temperature distribution is the temperature of the background region, and as one possible implementation manner, the average value of the temperatures of the background region is taken as the background region temperature, that is, in the environment temperature distribution diagram shown in fig. 3, the temperature values of the regions other than the heat source region are taken as the background region temperature, the initial temperature of the background region is set to T, and it is determined that the background region temperature is within the set temperature range, where the temperature range is set in advance and indicates the corresponding relationship between the temperature range and the compensation value and/or the compensation coefficient.
The temperature range comprises different range intervals, the different range intervals correspond to different compensation values and/or compensation coefficients, and the range interval belonging to the temperature range is determined according to the determined background area temperature, namely the corresponding compensation value and/or compensation coefficient is determined.
It should be noted that, in this embodiment, whether the background temperature belongs to the temperature range may be used to determine whether the current ambient temperature is in a reasonable range, and if the current ambient temperature is abnormally high or low, the application scenario of this embodiment is not met.
And 204, determining corresponding compensation information in the operation mode of the air conditioning equipment according to the ambient temperature information of the air conditioning equipment.
Wherein the compensation information comprises a compensation coefficient and/or a compensation value.
In one scenario, the compensation value is determined using the background region temperature, which is related to the determination of the compensation value, as shown in tables 1-1 and 1-2.
Table 1-1 shows compensation values for correcting the set temperature and corrected temperatures corresponding to different background area temperatures when the air conditioning apparatus is operating in the cooling mode when the cold-heat sensation value falls within a target range, for example, is greater than the preset value X, and table 1-2 shows compensation values for correcting the set temperature and corrected temperatures corresponding to the background area temperatures when the air conditioning apparatus is operating in the heating mode.
TABLE 1-1
| |Mt| | Temperature of background region | Compensation value | Set temperature (after correction) |
| ≥X | T (initial background temperature) | 0 | TSet (initial setting temperature) |
| ≥X | 1.1T (heating) | -2 (heating) | TSet-2 (heating) |
| … | … | … | … |
| ≥X | (1+0.1n) T (heating) | -n’(heating) | TSet-n’(heating) |
| <X | T’ | 0 | Maintaining the last set temperature |
Tables 1 to 2
In another scenario, the background region temperature is used to determine the compensation information, which is the compensation coefficient for correcting the wind speed, see table 2.
In table 2, compensation coefficients for correcting the wind speed for different background area temperatures when the air conditioning apparatus is operated in the heating mode and the cooling mode when the cold-heat feeling value falls within the target range, for example, is larger than the preset value X are shown.
TABLE 2
In still another scenario, compensation information is determined using the background area temperature, the compensation information being a compensation coefficient for correcting the wind speed and a compensation value for correcting the preset temperature, see tables 3-1 and 3-2.
The compensation values and compensation coefficients corresponding to the background zone temperatures when the air conditioning apparatus is operated in the cooling mode when the cold-heat feeling values belong to the target range, for example, are greater than the preset value X are shown in table 3-1, and the compensation values and compensation coefficients corresponding to the background zone temperatures when the air conditioning apparatus is operated in the heating mode are shown in table 3-2.
TABLE 3-1
TABLE 3-2
It should be noted that, after the initial operation parameter of the air conditioning equipment is determined according to the detected cold and hot feeling value of the heat source, the operation parameter is corrected according to the compensation information determined by the determined ambient temperature information, during the operation of the air conditioning equipment according to the corrected operation parameter, the cold and hot feeling value of the heat source is continuously monitored, if the cold and hot feeling value of the heat source is reduced to within the preset value X, the environment is considered to be adjusted to a proper temperature, the operation parameter of the air conditioning equipment is not corrected, and the operation of the finally corrected operation parameter is maintained.
And step 205, correcting the operation parameters according to the compensation information.
As a possible implementation manner, the compensation coefficient determined according to the ambient temperature information is multiplied by the wind speed to obtain the corrected wind speed, which is the corrected operation parameter for controlling the air conditioning equipment as shown in table 2.
As another possible implementation manner, the compensation value corresponding to the value range is added to the set temperature to obtain a corrected set temperature, which is the corrected operating parameter for controlling the air conditioning equipment in different operating modes as shown in tables 1-1 and 1-2.
As another possible implementation manner, the compensation coefficient corresponding to the environmental temperature information corresponding to the different value ranges is multiplied by the wind speed to obtain the corrected wind speed, and the compensation value corresponding to the environmental temperature information corresponding to the different value ranges is added to the set temperature to obtain the corrected set temperature, as shown in tables 3-1 and 3-2, when the environmental temperature information is in the different operation modes, the obtained corrected set temperature and wind speed are the corrected operation parameters for controlling the air conditioning equipment.
Optionally, before the operation parameter is corrected by using the compensation information determined by the ambient temperature information, it may be further determined that the cold and hot feeling value belongs to the target range, specifically, an absolute value of the cold and hot feeling value is determined according to the detected cold and hot feeling value, whether the absolute value of the cold and hot feeling value belongs to the preset target range is continuously monitored, if the absolute value of the cold and hot feeling value always belongs to the target range, it is considered that the current heat source is continuously too hot or too cold, and the operation parameter is determined based on the currently determined cold and hot feeling value of the heat source, which may result in inaccurate setting of the operation parameter and need to correct the determined operation parameter, and conversely, the operation parameter does not need to be corrected.
And step 206, controlling the refrigerating capacity or the heating capacity of the air conditioning equipment according to the corrected operation parameters.
Specifically, reference may be made to step 104 in the previous embodiment, which has the same principle and is not described herein again.
For clarity of explanation on the control method of the air conditioning equipment in the previous embodiment, the air conditioning equipment is taken as an air conditioner, and the air conditioner operates in a heating mode by way of example, and is exemplified.

In one scenario, compensation information corresponding to temperature information of a background area in environment temperature information is used to adjust an operation parameter as follows:
as a possible implementation manner, the set temperature is corrected by the compensation value corresponding to the background area temperature, and the corrected set temperature is shown in table 4.
| |M4| | Temperature of background region | Corrected temperature |
| ≥1 | T＝19.2℃ | TSet＝30℃ |
| ≥1 | T＝21.3℃ | TSet＝28℃ |
| ≥1 | T＝23.5℃ | TSet＝26℃ |
| <1 | T＝24.1℃ | TSet＝26℃ |
TABLE 4
As another possible implementation manner, the wind speed is corrected by the compensation coefficient corresponding to the temperature of the background area, and the corrected wind speed is shown in table 5.
TABLE 5
As another possible implementation manner, the set temperature and the wind speed are corrected by the compensation value and the compensation coefficient corresponding to the temperature of the background area, and the corrected set temperature and wind speed are shown in table 6.
TABLE 6
Through the adjustment of the operation parameters of the air conditioner, the air conditioner is enabled to operate under the corrected operation parameters, and the environment temperature distribution map is detected again, fig. 4 is a schematic diagram of the corrected environment temperature distribution provided by the embodiment of the invention, and as can be seen by comparing fig. 3 and fig. 4, after the air conditioner is controlled according to the corrected operation parameters, the obtained environment temperature distribution tends to be stable, namely, the purpose of automatically adjusting the air is achieved, the environment temperature is enabled to be more comfortable, the false cold and hot sensing values determined by false detection heat sources can be reduced to the maximum extent, so that the probability of inaccurate determined operation parameters is achieved, and the user experience comfort is greatly improved.
It should be noted that the numerical values in the above table of the embodiment of the present invention are only examples, and those skilled in the art can adjust the numerical values according to actual situations, for example, increase or decrease the numerical values, and the distribution of the range intervals does not necessarily adopt the division described in this embodiment.
