The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method, device, and air conditioning apparatus of an embodiment of the present invention are described below with reference to the accompanying drawings.
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:
step 101, determining a cold and hot sensing value of a heat source according to an environmental parameter detection result of the current environment.
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.
Alternatively, if a plurality of heat sources are detected, the maximum thermal sensation value among the thermal sensation values of the plurality of heat sources is used as the detected thermal sensation value, or the thermal sensation values of the plurality of heat sources are averaged, and the average thermal sensation value is used as the detected thermal sensation value.
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, correcting the detected cold and hot feeling value according to the ambient temperature.
Specifically, according to the ambient temperature, a compensation value or a compensation coefficient corresponding to the operation mode of the air conditioning equipment is determined, the compensation value is added to the detected cold and hot sensing value to obtain a corrected cold and hot sensing value, or the compensation coefficient is multiplied by the detected cold and hot sensing value to obtain a corrected cold and hot sensing value, and the cold and hot sensing value is compensated through the ambient temperature, so that the accuracy of the cold and hot sensing value is improved.
The compensation value or the compensation coefficient corresponding to the ambient temperature is determined in advance, and as a possible implementation manner, the compensation value or the compensation coefficient may be determined in advance through a large amount of experimental data according to an operation mode of the air conditioner, which is not limited in this embodiment.
And 103, reducing the refrigerating capacity or the heating capacity of the air conditioning equipment according to the corrected cold and heat induction value.
Specifically, according to the corrected cold and hot sensing value, the swing speed of an air guide strip of the air conditioning equipment is reduced, or according to the corrected cold and hot sensing value, the air supply speed of the air conditioning equipment is reduced, or according to the corrected cold and hot sensing value, the set temperature of the air conditioning equipment is reduced under the heating operation mode, the set temperature of the air conditioning equipment is increased under the refrigerating 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 present application, the cooling amount or the heating amount may be specifically adjusted by the air supply amount.
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 is0Indicating the amount of cooling or heating, 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 value is kept constant, and the air supply quantity G is reduced to reduceThe cooling capacity or the heating capacity of the air conditioning equipment.
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 wind speed of the corresponding air supply 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 wind speed of the corresponding air supply is smaller, and the refrigerating capacity or the heating capacity corresponding to the air supply angle is smaller.
As a second possible implementation manner, when the air guide strip of the air conditioning apparatus swings to each air supply angle, the swing speed of the air guide strip is adjusted according to the corresponding control parameter. 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 swing speed of the air guide strip is smaller, 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 swing speed of the air guide strip is larger, and the refrigerating capacity or the heating capacity corresponding to the air supply angle is smaller.

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.

In the control method of the air conditioning equipment of the embodiment, the cold and hot sensing values of the heat source are determined according to the environmental parameter detection result of the current environment, the detected cold and hot sensing values are corrected according to the environmental temperature, the refrigerating capacity or the heating capacity of the air conditioning equipment is reduced according to the corrected cold and hot sensing values, the detected cold and hot sensing values are corrected according to the environmental temperature, the accuracy of the cold and hot sensing values is improved, on one hand, when other heat sources existing in the environment are avoided, the air conditioning equipment continuously adjusts the environmental parameters to a numerical range which is not suitable for a human body, the automatic adjustment accuracy of the air conditioning equipment is improved, on the other hand, even when other heat sources except the human body do not exist in the environment, the air conditioning equipment is compensated according to the air conditioning parameters determined according to the cold and hot sensing values, and can be prevented from continuously operating with higher adjustment efficiency, under the condition of ensuring the environment adjusting effect and not influencing the user experience, the energy consumption is reduced.
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:
step 201, determining a cold and hot sensing value of a heat source according to the environmental parameter detection result of the current environment.
Specifically, the ambient temperature distribution is detected through the array type infrared thermopile sensors, and the cold and hot sensing values of the heat source are determined according to the ambient temperature distribution and the operation mode of the air conditioning equipment.
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 infrared thermopile sensor, and different corresponding temperature distributions in the ambient temperature distribution diagram are obtained by detection, as shown in fig. 3. The region with the highest temperature in the temperature distribution map is identified as the heat source region, i.e., the region a corresponding to the dotted rectangle indicated by the arrow in fig. 3, and the temperature of the heat source is determined according to the heat source region.
In the present invention, the heat source may be a plurality of heat sources, and the maximum value of the cold and heat feeling values of the plurality of heat sources is set as the detected cold and heat feeling value, or the average value of the cold and heat feeling values of the plurality of heat sources is set as the detected cold and heat feeling value.
Step 202, obtaining the environmental temperature distribution, and determining the environmental temperature for the background area except the heat source area according to the environmental temperature distribution.
The ambient temperature distribution is detected by the array infrared thermopile sensor and used for indicating the ambient temperature of each area.
Specifically, the ambient temperature is determined for the background region other than the heat source region based on the ambient temperature distribution, and as one possible implementation, the average value of the temperature of the background region is taken as the ambient temperature, that is, the average value of the temperature values of the regions other than the a region corresponding to the heat source indicated by the arrow in the ambient temperature distribution diagram shown in fig. 3 is taken as the ambient temperature.
Step 203, determining that the ambient temperature is within the set temperature range, thereby determining a corresponding compensation value or compensation coefficient.
Wherein, the ambient temperature of the background area and the compensation value are in a positive relationship.
Specifically, whether the ambient temperature of the background area is within a set temperature range or not is determined, and if the ambient temperature is within the set temperature range, the calculated cold and hot feeling value is compensated.
As a possible implementation manner, the temperature range may be divided into different temperature range sections, the temperature range section and the compensation value have a corresponding relationship, that is, the different temperature range sections correspond to different compensation values, that is, a section in which the ambient temperature is in the set temperature range is determined, that is, the corresponding compensation value can be determined, and meanwhile, in the cooling and heating operation mode, the ambient temperature of the background area and the compensation value have a positive relationship, that is, the ambient temperature of the background area increases, and the corresponding compensation value also increases, as a possible implementation manner, the increase of the compensation value may be increased with the increase of the ambient temperature of the background area in a fixed ratio or a fixed value increase manner, for example, when the ambient temperature of the background area is 23 degrees celsius, the compensation value is-1, and when the ambient temperature of the background area is 25 degrees celsius, the offset value is-0.5, and the ambient temperature of the background area is 26 degrees celsius, the offset value is 0, i.e. the offset value increases with a fixed increase of +0.5 with an increase of the ambient temperature of the background area. As another possible implementation manner, the increase of the compensation value may also increase with the increase of the ambient temperature of the background area in a non-fixed proportion or non-fixed value increase manner, for example, when the ambient temperature of the background area is 23 degrees celsius, the compensation value is-1, when the ambient temperature of the background area is 25 degrees celsius, the compensation value is-0.5, and when the ambient temperature of the background area is 26 degrees celsius, the compensation value is-0.1, that is, the increase of the compensation value increases with the increase of the ambient temperature of the background area in a non-fixed proportion or non-fixed value increase manner.
Table 1-1 is a relationship between the temperature range interval and the corresponding compensation value in the cooling mode.
Temperature range (. degree. C.) Compensation value
20≤X<24 -1
24≤X<26 -0.5
26≤X<28 +0
28≤X<30 +0.5
30≤X +1
TABLE 1-1
As can be seen from table 1-1, if the cold and hot sensing values of the heat source corresponding to the area a indicated by the arrow in fig. 3 are denoted as M, for example, the value of M is 1, and the current background area temperature is 25.9, the temperature range corresponding to the background area temperature is greater than or equal to 24 ℃, and the corresponding compensation value is-0.5, as shown in table 1-1.
As another possible implementation, the temperature range may be divided into different temperature range intervals, the temperature range intervals have a corresponding relationship with the compensation coefficients, i.e. the different temperature range intervals, correspond to different compensation factors, i.e. the intervals in which the ambient temperature is in the set temperature range are determined, the corresponding compensation coefficient can be determined, meanwhile, under the operation mode of refrigeration and heating, the environmental temperature of the background area and the compensation coefficient are in a positive relation, the increase of the compensation coefficient may be increased with the increase of the ambient temperature of the background area in a fixed proportion or fixed value manner, or may be increased with the increase of the ambient temperature of the background area in an unfixed proportion or fixed value manner, which is the same as the realization principle of the forward relationship between the compensation value and the ambient temperature of the background area, and is not described herein again.
Table 1-2 is a relationship between the temperature range interval and the corresponding compensation coefficient in the cooling mode.

Figure BDA0001921224540000081
Tables 1 to 2
As can be seen from table 1-2, different background region temperatures correspond to regions belonging to different temperature ranges, that is, correspond to different compensation values, and as shown in table 1-2, in the cooling mode, when the ambient temperature is 31 degrees, the temperature range corresponding to the background region temperature is greater than or equal to 30 degrees, the corresponding compensation value is 1, after a period of operation, the M value is 1, the current background region temperature is 25.9, the temperature range corresponding to the background region temperature is greater than or equal to 24 degrees, and the corresponding compensation value is-0.5.
It should be noted that, in this embodiment, whether the background area temperature belongs to the set temperature range or not may be used to determine whether the current ambient temperature is within a reasonable range, and if the current ambient temperature is abnormally high or low, the current ambient temperature is not in accordance with the application scenario of this embodiment, and the ambient temperature cannot be automatically adjusted by compensating the cold and hot feeling value.
And 204, correcting the detected cold and hot sensing values according to the compensation value or the compensation coefficient corresponding to the environment temperature.
Specifically, the compensation value corresponding to the ambient temperature and the detected cold-heat-sensitivity value are added to obtain a corrected cold-heat-sensitivity value, for example, if the ambient temperature, that is, the compensation value corresponding to the ambient temperature of the background region is-0.5, the compensation value corresponding to the ambient temperature of the background region and the cold-heat-sensitivity value M are added, that is, 1-0.5 is 0.5, and the corrected cold-heat-sensitivity value is 0.5.
