[0028] For example, the air conditioner control method provided in the embodiments of the present disclosure includes a series of steps, but the air conditioner control method provided in the embodiments of the present disclosure is not limited to the recited steps. Similarly, the air conditioner control device provided in the embodiments of the present disclosure includes a series of units, but the device provided in the embodiments of the present disclosure is not limited to including the explicitly recited units, and may further include units required for obtaining relevant information or processing based on the information.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0030] It can be understood that in the specific implementation manners of the present application, when related data is involved and the embodiments of the present application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of the related data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0031] Figure 1 The flowchart of the air conditioner control method according to an embodiment of the present application is schematically shown. The execution subject of the air conditioner control method can be any air conditioner control device with processing capabilities, and the air conditioner control device can be installed in a designated device, and the designated device can include but is not limited to the air conditioner itself, mobile phones, computers, smart watches, and other household electrical appliances, etc.

[0032] In a specific embodiment of the present application, the air conditioner control device as the execution subject of the air conditioner control method is installed inside the air conditioner itself. It should be noted that the air conditioner in the embodiments of the present application may include an outdoor unit and one or more indoor units.

[0033] As Figure 1 shown, the air conditioner control method may include steps S110 to S140.

[0034] Step S110: Obtain real-time temperature control reference data, or estimate the temperature control reference data at a future time;

[0035] Step S120: Calculate the building envelope load, indoor living load, indoor air heat capacity, indoor equipment load, and air conditioner input cooling capacity according to the temperature control reference data;

[0036] Step S130: Calculate based on the building envelope load, the indoor living load, the indoor air heat capacity, the indoor equipment load, and the air conditioner input cooling capacity to obtain the indoor load of the air conditioner;

[0037] Step S140: Control the air conditioner according to the indoor load of the air conditioner.

[0038] During the process of controlling the air conditioner, the actual temperature control reference data can be obtained in real time through a network, preset sensors (such as temperature sensors, ultrasonic sensors, etc.) or associated devices (such as electricity meters, etc.), and / or the temperature control reference data at a future time (the future time is the time after the real-time time) can be estimated in advance based on the obtained actual temperature control reference data. These temperature control reference data can include, but are not limited to, one or more of the outdoor ambient temperature, indoor ambient temperature, indoor living body data, indoor set temperature, indoor energy consumption power, and temperature and humidity data at the inlet and outlet of the indoor unit.

[0039] Calculate the building envelope load, indoor living load, indoor air heat capacity, indoor equipment load, and air conditioner input cooling capacity according to the temperature control reference data. Then, the building envelope load is the load corresponding to the building envelope such as the walls of the building site, the indoor living load is the load corresponding to the living bodies such as people or animals in the building site, the indoor air heat capacity is the heat capacity of the air in the building site, the indoor equipment load is the load of other equipment except the air conditioner in the building site, and the air conditioner input cooling capacity is the cooling capacity input by the air conditioner.

[0040] By comprehensively calculating the building envelope load, indoor living load, indoor air heat capacity, indoor equipment load, and air conditioner input cooling capacity, the indoor load of the place where the air conditioner is located (the indoor load can also be called the building load) can be accurately obtained. Thus, based on the real-time temperature control reference data or the temperature control reference data at a future time, the indoor load of the place where the air conditioner is located can be dynamically, real-time, and accurately calculated or predicted in advance, without relying on a large amount of historical data for training or building a model.

[0041] Furthermore, based on the indoor load, real-time control or pre-control of the air conditioner can be performed, so as to reasonably arrange energy use, improve energy efficiency and reduce waste. For example, according to the calculated indoor load, query the corresponding capacity value of the indoor load from the preset capacity table, and control the output capacity of the outdoor unit of the air conditioner based on this capacity value, where the capacity value can be the compressor frequency and / or valve opening degree, etc.

[0042] In the way of the embodiment of the present application, by calculating the envelope load, indoor living load, indoor air heat capacity, indoor equipment load and air conditioner input cooling capacity according to the temperature control reference data, and further calculating the indoor load by comprehensively considering the envelope load, indoor living load, indoor air heat capacity, indoor equipment load and air conditioner input cooling capacity, it is possible to dynamically and accurately calculate or predict in advance the indoor load of the place where the air conditioner is located based on the real-time temperature control reference data or the temperature control reference data at a future moment, without relying on a large amount of historical data, the overall implementation difficulty is low, and it can be effectively applied to the air conditioner in the indoor home environment.

[0043] The following describes Figure 1 Specific optional embodiments of each step when performing air conditioner control in the embodiment.

[0044] In one embodiment, referring to Figure 2 , the temperature control reference data includes the temperature and humidity data of the air inlet and outlet of the indoor unit, the air volume of the fan and the air density; the calculation method of the air conditioner input cooling capacity includes: step S210, calculating the air inlet enthalpy value and the air outlet enthalpy value of the indoor unit according to the temperature and humidity data of the air inlet and outlet of the indoor unit; step S220, calculating the difference between the air inlet enthalpy value and the air outlet enthalpy value to obtain the air inlet and outlet enthalpy difference; step S230, multiplying the air volume of the fan, the air density, the air inlet and outlet enthalpy difference by the cooling capacity correction coefficient to obtain the air conditioner input cooling capacity.

[0045] In this embodiment, the temperature control reference data includes the temperature and humidity data of the air inlet and outlet of the indoor unit, the air volume of the fan and the air density; the temperature and humidity data of the air inlet and outlet of the indoor unit can be obtained in real time by presetting temperature and humidity sensors, the air volume of the fan corresponding to the corresponding gear can be determined according to the real-time fan gear, and the air density can be a predetermined density; since the air conditioner control is usually constant, when estimating the temperature control reference data, the estimated temperature and humidity data, air volume of the fan and air density at a future moment can be assumed to be unchanged and the same as the real-time temperature and humidity data, air volume of the fan and air density.

[0046] The air inlet enthalpy and air outlet enthalpy of the indoor unit can be calculated based on the temperature and humidity data of the indoor unit's air inlet and outlet. The air inlet enthalpy reflects the heat state of the indoor unit's air inlet, and the air outlet enthalpy reflects the heat state of the indoor unit's air outlet. The difference between the air inlet enthalpy and the air outlet enthalpy is calculated to obtain the air inlet and outlet enthalpy difference.

[0047] In some embodiments, the fan air volume, air density, and air inlet and outlet enthalpy difference are multiplied, and the multiplied value is used as the air conditioning input cooling capacity. In the embodiment, the fan air volume, air density, air inlet and outlet enthalpy difference and the cooling capacity correction coefficient (the cooling capacity correction coefficient can be preset according to actual conditions) are multiplied to more accurately obtain the air conditioning input cooling capacity. Specifically, in the embodiment, according to the formula Q 冷 =F 量 *ρ 密 *(h 进 -h 出 )*K1 calculates the air conditioning input cooling capacity Q 冷 , where F 量 That is, the fan air volume, ρ 密 That is, the air density, h 进 Refers to the air inlet enthalpy, h 出 Refers to the air outlet enthalpy value, K1 is the refrigeration capacity correction coefficient.

[0048] Further, in one embodiment, the calculating of the air inlet enthalpy value and the air outlet enthalpy value of the indoor unit according to the temperature and humidity data of the air inlet and outlet of the indoor unit may include:

[0049] According to the formula h 进 =A1+B1*T1+C1*RH1+D1*T1 2 +E1*T1*RH1+F1*RH1 2 +G1*T1 3 +H1*T1 2 *RH1+I1*T1*RH1 2 +J1*RH1 3 The air inlet enthalpy is calculated as follows: 进 Refers to the air inlet enthalpy value, T1 refers to the dry bulb temperature at the air inlet of the indoor unit, RH1 refers to the air inlet humidity at the air inlet of the indoor unit, A1, B1, C1, D1, E1, F1, G1, H1, I1, J1 are the predetermined inlet enthalpy value calculation coefficients;

[0050] According to the formula h 出 =A2+B2*T2+C2*RH2+D2*T2 2 +E2*T2*RH2+F2*RH2 2 +G2*T2 3 +H2*T22 *RH2 + I2 * T2 * RH2 2 + J2 * RH2 3 The calculated air outlet enthalpy value, where h 出 represents the air outlet enthalpy value, T2 represents the dry bulb temperature at the air outlet of the indoor unit, RH2 represents the air outlet humidity at the air outlet of the indoor unit, and A2, B2, C2, D2, E2, F2, G2, H2, I2, J2 are predetermined outlet enthalpy value calculation coefficients.

[0051] In this embodiment, the air inlet enthalpy value h 进 and the air outlet enthalpy value h 出 are calculated respectively according to the above specific formulas. The applicant finds that based on the above formulas for calculating the air inlet enthalpy value and the air outlet enthalpy value, the air inlet enthalpy value and the air outlet enthalpy value can be calculated extremely accurately, thereby further ensuring the calculation accuracy of the cooling capacity input to the air conditioner and improving the control reliability of the air conditioner as a whole.

[0052] Among them, the coefficients at the same positions in "A1, B1, C1, D1, E1, F1, G1, H1, I1, J1" and "A2, B2, C2, D2, E2, F2, G2, H2, I2, J2" can be the same or different. For example, the coefficients A1 and A2 at the same position can be the same or different.

[0053] In an example of the present application, the coefficients at the same positions in "A1, B1, C1, D1, E1, F1, G1, H1, I1, J1" and "A2, B2, C2, D2, E2, F2, G2, H2, I2, J2" are the same. A1, B1, C1, D1, E1, F1, G1, H1, I1, J1 are -7.352, 1.911, 0.2777, -0.03593, -0.0133, 0.0004619, 0.0008764, 2.175, -2.428*e -8 , and A2, B2, C2, D2, E2, F2, G2, H2, I2, J2 are also -7.352, 1.911, 0.2777, -0.03593, -0.0133, 0.0004619, 0.0008764, 2.175, -2.428*e -8 , and the applicant finds that in this example, the accuracy of the air inlet enthalpy value and the air outlet enthalpy value can be further effectively ensured.

[0054] In one embodiment, refer to Figure 3, the temperature control reference data includes the number of living bodies indoors and the living states of each living body; the calculation method of the indoor living body load may include: step S310, determining the heat dissipation of each living body according to the living state of each living body; step S320, calculating according to the number of living bodies indoors, the heat dissipation of each living body and the living body load correction coefficient to obtain the indoor living body load.

[0055] In this embodiment, the temperature control reference data includes the number of living bodies indoors and the living states of each living body. The number of living bodies indoors may include the total number of living bodies of different types (for example, the total number of human living bodies and the total number of puppy living bodies). The living state may be standing, sitting, squatting, etc. For the same type of living body, a corresponding heat dissipation is preset for each living state. For example, the preset heat dissipation for a person standing is 1, the preset heat dissipation for a person lying is 2, and the preset heat dissipation for a dog standing is 3. The number of living bodies indoors and the living states of each living body are detected by preset ultrasonic or infrared sensors; according to the obtained number of living bodies indoors and the living states of each living body, through permutation and combination, optimization, etc., the number of living bodies indoors and the living states of each living body at a future moment can be estimated.

[0056] The number of living bodies indoors and the heat dissipation of each living body can accurately reflect the heat dissipation of the living bodies in the building site. According to the number of living bodies indoors and the heat dissipation of each living body, and supplemented by the living body load correction coefficient for calculation, the indoor living body load can be accurately calculated. Among them, a corresponding living body load correction coefficient can be preset for each type of living body. It can be understood that in other alternative ways, the indoor living body load can be directly calculated according to the number of living bodies indoors and the heat dissipation of each living body without using the living body load correction coefficient.

[0057] Further, in an embodiment, calculating according to the number of living bodies indoors, the heat dissipation of each living body and the living body load correction coefficient to obtain the indoor living body load may include: determining the total heat dissipation of the corresponding type of living body according to the living state of each type of living body, multiplying the total number of each type of living body, the total heat dissipation of the living body and the living body load correction coefficient to obtain the living body load of each type; adding the living body loads of all types to obtain the indoor living body load.

[0058] When determining the total heat dissipation of the corresponding type of living body according to the living state of each type of living body, for example, there are human body 1 and human body 2 among humans. The living state of human body 1 is standing, and the heat dissipation of human body 1 is the preset heat dissipation 1. The living state of human body 2 is lying, and the heat dissipation of human body 2 is the preset heat dissipation 2. Thus, adding the preset heat dissipation 1 and the preset heat dissipation 2 to obtain the total heat dissipation of humans. In some other ways, the corresponding heat dissipation can also be further determined by combining the size and living state of each living body.

[0059] Multiply the total number of living bodies of each type, the total heat dissipation of the living bodies, and the living body load correction factor to obtain the living body load of each type. For example, for humans, Q 人 = n 人 * Q 人散热 * K2 人 , Q 人 That is, the living body load of humans, n 人 That is, the total number of living bodies of people, Q 人散热 That is, the total heat dissipation of the living bodies of people, K2 人 That is, the living body load correction factor corresponding to humans.

[0060] In one embodiment, the temperature control reference data includes the indoor volume, air density, specific heat capacity at constant pressure of air, indoor ambient temperature, and user-set temperature; the calculation method of the indoor air heat capacity may include:

[0061] Multiply the indoor volume by the air density to obtain the air quality; subtract the user-set temperature from the indoor ambient temperature to obtain a first temperature difference; multiply the air quality, the specific heat capacity at constant pressure of air, the first temperature difference, and the specific heat capacity correction factor to obtain the indoor air heat capacity.

[0062] In this embodiment, the temperature control reference data includes the indoor volume, air density, specific heat capacity at constant pressure of air, indoor ambient temperature, and user-set temperature. The indoor volume, air density, specific heat capacity at constant pressure of air (specific heat capacity of air in a predetermined pressure environment), and user-set temperature can be assumed to be constant. The indoor ambient temperature can be detected in real time through a pre-set temperature sensor, and the indoor ambient temperature at a future moment can be predicted according to the temperature control parameters.

[0063] In this embodiment, specifically, the indoor air heat capacity C can be accurately calculated according to the formula C = M * c(T 室内 - T 设定 ) * K3 and M = V * P, where V is the indoor volume, P is the air density, M is the air quality, T 室内 - T 设定 is the first temperature difference, c is the specific heat capacity at constant pressure of air, and K3 is the specific heat capacity correction factor.

[0064] Furthermore, in one embodiment, the temperature control reference data includes the outdoor ambient temperature, indoor ambient temperature, wall area, and wall heat transfer coefficient; the calculation method of the enclosure structure load may include: subtract the indoor ambient temperature from the outdoor ambient temperature to obtain a second temperature difference; multiply the wall area, the wall heat transfer coefficient, the second temperature difference, and the structure load correction factor to obtain the enclosure structure load.

[0065] In this embodiment, the temperature control reference data includes the outdoor ambient temperature, the indoor ambient temperature, the wall area, and the wall heat transfer coefficient. The indoor ambient temperature can be detected in real time by a pre-installed temperature sensor, and the indoor ambient temperature at a future time can be predicted according to the temperature control parameters. The outdoor ambient temperature can be detected in real time by a pre-installed temperature sensor, and the outdoor ambient temperature at a future time can be predicted according to the outdoor weather conditions at that future time. The wall area and the wall heat transfer coefficient are usually assumed to be constant.

[0066] In this embodiment, specifically, according to the formula Q 围 =K 传 *F 面 *(T 室外 -T 室内 )*K4, the enclosure structure load Q 围 can be accurately calculated, where K 传 is the wall heat transfer coefficient, F 面 is the wall area, T 室外 is the outdoor ambient temperature, T 室内 is the indoor ambient temperature, and K4 is the structure load correction coefficient.

[0067] Furthermore, in one embodiment, the temperature control reference data includes the indoor energy consumption power; the calculation method of the indoor equipment load can include: multiplying the indoor energy consumption power by the electro-thermal energy conversion correction coefficient to obtain the indoor equipment load.

[0068] In this embodiment, the temperature control reference data includes the indoor energy consumption power, the real-time indoor energy consumption power is detected by a general electricity meter, and it can be assumed that the indoor energy consumption power at a future time remains unchanged. Furthermore, according to the formula Q 设 =W 电 *K5, the indoor equipment load Q 设 can be accurately calculated, where W 电 is the indoor energy consumption power, and K5 is the electro-thermal energy conversion correction coefficient.

[0069] Furthermore, in one embodiment, by calculating based on the enclosure structure load, the indoor living body load, the indoor air heat capacity, the indoor equipment load, and the air conditioner input cooling capacity, the indoor load of the air conditioner can be: summing the enclosure structure load, the indoor living body load, the indoor air heat capacity, the indoor equipment load, and the air conditioner input cooling capacity, and taking the sum as the indoor load of the air conditioner.

[0070] Further, in one embodiment, calculating based on the enclosure structure load, the indoor living body load, the indoor air heat capacity, the indoor equipment load, and the air conditioner input cooling capacity to obtain the indoor load of the air conditioner may be: according to a predetermined weighting coefficient, performing a weighted sum of the enclosure structure load, the indoor living body load, the indoor air heat capacity, the indoor equipment load, and the air conditioner input cooling capacity, and taking the value obtained by the weighted sum as the indoor load of the air conditioner.

[0071] In addition, an embodiment of the present application further provides an air conditioner control device, and the air conditioner control device can be applied to a control device. As Figure 4 shown, Figure 4 The block diagram of the air conditioner control device according to an embodiment of the present application is shown. Specifically: the air conditioner control device 400 may include a processor 401 with one or more processing cores, and a memory 402 with one or more computer-readable storage media.

[0072] The processor 401 can, according to instructions, load the executable file corresponding to the process of one or more computer programs into the memory 402, and the processor 401 runs the computer programs stored in the memory 402, so as to implement various functions in the embodiments of the foregoing air conditioner control method of the present application.
