In this context, various embodiments may be referred to individually or collectively by the term "invention," for convenience only, and if more than one invention is disclosed, it is not intended to automatically limit the scope of the application to any A single invention or inventive concept. Herein, relational terms such as first and second are used merely to distinguish one entity or operation from another entity or operation, and do not require or imply any actual relationship between the entities or operations or order. Furthermore, the terms "comprises" or "comprising" or "comprising" or any other variations are intended to encompass a non-exclusive inclusion, such that a process, method, or device that includes a plurality of elements includes not only those elements but also other items not specifically listed. Elements. The various embodiments herein are described in a progressive manner, and each embodiment focuses on differences from other embodiments, and the same similar parts between the various embodiments may be referred to each other. For the structures, products, and the like disclosed in the embodiments, since they correspond to the parts disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method parts.

In the prior art, it is necessary to calculate the power saving amount of the air conditioner after the air conditioner performs the power saving control. The power saving is determined according to the difference between the estimated power consumption of the air conditioner and the actual power consumption of the air conditioner during the period after the power saving control, such as the adjustment of the air conditioner from the first state to the second state, that is, the T period. . In the above process, the actual power consumption of the air conditioner can be calculated according to the power and time of the air conditioner feedback, but the estimated power consumption of the air conditioner needs to be calculated according to the laboratory data. However, due to the geographical location of the air conditioner, outdoor environment, indoor environment, type of house, model and other factors will affect the power consumption of the air conditioner, so the laboratory data can not reflect the actual operating state of the air conditioner, the calculated estimated power consumption error Larger. The overall concept of the present invention is to obtain the model and operating parameters of the plurality of air conditioners in the first state during the T time period; and calculate the estimated power consumption in the T period when the air conditioner is in the first state according to the above parameters. .

In the present invention, the first state refers to a state before the air conditioner performs power saving control, and the second state refers to a state after the air conditioner performs power saving control, and the first state and the second state may be settings for the air conditioner. The temperature is adjusted, for example, the first temperature is adjusted to the second temperature; or the air speed is adjusted, for example, the first wind speed is adjusted to the second wind speed.

The first air conditioner is a type of air conditioner that retrieves its model and operating parameters from the database when calculating the estimated power consumption of the second air conditioner; the operating state of the first air conditioner in the T period is compared with the second air conditioner The operating state before the power saving control is the same, that is, the first air conditioner is in the first state. The first air conditioner and the second air conditioner are located in the same area, such as the same city or the same area, and the outdoor environment is basically the same.

The second air conditioner is an air conditioner that performs power saving control in the present invention and needs to calculate its estimated power consumption. The second air conditioner is in the first state before the power saving control, and is in the first state; after the power saving control is performed on the second air conditioner, the second air conditioner is adjusted from the first state to the second state.

The model number of the first air conditioner or the second air conditioner refers to a type of parameter that can reflect the number of air conditioners and the energy consumption level, such as the machine model and the machine code.

The energy consumption level can be represented by the energy efficiency label, which can be divided into five grades according to national standards. The grade 1 indicates that the product has reached the international advanced level and the energy consumption is the lowest; the grade 2 indicates that the product is more energy-saving; the grade 3 indicates the product energy. The efficiency is the average level of the Chinese market; the grade 4 indicates that the product energy efficiency is lower than the market average; the grade 5 is the product market access indicator, and the products below the level are not allowed to be produced and sold; or it may be in accordance with the industry standard or Enterprise standards, graded.

The power correction coefficient is determined according to the model of the first air conditioner and the model of the second air conditioner, and is used to correct the power of the first air conditioner, thereby calculating the correction power of the first air conditioner.

The estimated power consumption is the power consumption of the second air conditioner before the power saving control, that is, in the first state, corresponding to the power consumption in the T period.

The actual power consumption is the power consumption of the second air conditioner after the power saving control, that is, in the second state, corresponding to the T time period.

In the embodiment, when estimating the power consumption of the air conditioner, the data used is not calculated according to the laboratory data, but the model and operating parameters of the n first air conditioners in the same area and the same running time period are retrieved, and according to these The parameter calculates the estimated power consumption W1 of the second air conditioner. In this embodiment, the operating parameters of the n first air conditioners are collected during the same running time period, and the parameters are determined by the geographic location, outdoor environment, indoor environment, floor type, model, etc. of each of the first air conditioners. In addition, the estimated power consumption W1 of the second air conditioner also corresponds to the time period, so the power consumption of the air conditioner converted by the embodiment is more accurate than the calculation method by the experimental data in the prior art.

In some optional embodiments, the set temperature of the second home appliance before the power saving control is the first temperature, and after the power saving control, the set temperature is set to the second temperature.

Consumption. In this embodiment, the second home appliance adjusts the set temperature to achieve the purpose of power saving. Therefore, in the embodiment, the first state in which the n first home appliances are located refers to the set temperature being the first temperature. The second state in which the second home appliance is subjected to the power saving control means that the set temperature is the second temperature.

In some optional embodiments, in step S101, the model and operating parameters of the n first air conditioners may be obtained from the cloud server or other devices. A cloud server or other device is used to monitor the running status of the air conditioner in the same area, such as the first state and the second state. When the power of the air conditioner changes, the cloud server or other device is actively reported to the current power. Therefore, the cloud server or other device also records the power of each air conditioner and the running time corresponding to the power.

In some optional embodiments, in step S102, the power correction coefficient α _{i of the} n first air conditioners may be queried from a local or cloud server or other device.

Optionally, in the database, the power correction coefficient α _i of the air conditioner of different models is recorded, and according to the model of the first air conditioner and the model of the second air conditioner, the power correction coefficient α _{i of the} first air conditioner can be directly queried.

Table 1

Among them, the model of the air conditioner corresponds to the number of air conditioners and the energy consumption level. By identifying the model of the air conditioner, the number of air conditioners and the energy consumption level can be determined.

Further, the step S102 specifically includes:

For example, the number of the second air conditioner corresponds to 1P, and the energy consumption level is the first-level energy consumption, then a ₀ is A11; a total of n first air conditioners are obtained, numbered 1 to n, where the number is 3 (ie The model number of the first air conditioner of i=3) corresponds to 3P, and the energy consumption level is secondary energy consumption, then a ₃ = A42; according to the above information and formula 4, α ₃ = A42/A11 can be calculated. Similarly, the coefficients α _{i of the} n first air conditioners, i.e., α ₁ , α ₂ , ..., α _n , can be calculated.

In some illustrative embodiments, step S103 includes:

Calculating a corrected power P _i of each of the n first air conditioners;

;

According to the average corrected power of the n first air conditioners

further,

Calculating the average corrected power of the n first air conditioners according to Formula 2

further,

Calculating an estimated power consumption W1 of the second air conditioner in the T period according to Equation 3;

In the above embodiment, a specific calculation method and a corresponding formula for calculating the estimated power consumption W1 are given. After acquiring the model and state parameters of the n first air conditioners, calculating the corrected power P _{i of} each of the first air conditioners, and then averaging the calculated correction powers P _{i to} calculate the average corrected power of the n first air conditioners

That is, the second air conditioner is in the first state before the power saving control is performed, and the estimated power consumption in the T time end; then the calculated in the above step

Multiplying T, the estimated power consumption W1 of the second air conditioner during the T period is calculated.

In some optional embodiments, the method further includes calculating a power saving amount of the second air conditioner after performing the power saving control. For example, after the second air conditioner adjusts the temperature from the first temperature to the second temperature after performing the power saving control, the actual power consumption W2 of the second air conditioner in the T period is calculated, and then the T period is calculated according to W1 and W2. The power saving of the second air conditioner, that is, the power consumption saving value ΔW.

Further, according to Formula 5, the power consumption saving value ΔW of the second air conditioner in the T period is calculated;

ΔW=W1-W2 (5).

Further, the step of calculating the actual power consumption W2 specifically includes:

Obtaining a second parameter in the air-conditioning operation period T, comprising: a second air-conditioning in the reported time period T P _y m-th power, and the operating time corresponding to each of the power P _y t _y;

Calculate the actual power consumption W2 according to Equation 6:

Where y=1, 2, . . . , m, m is a positive integer not less than 1.

In the above embodiment, the actual power consumption W2 is calculated according to the operating parameter of the second air conditioner in the T time period, and the second air conditioner reports its current power whenever the power changes during operation, thereby acquiring at least the T time period. One running power, and the corresponding running time.

Optionally, the operating parameter of the second air conditioner in the T time period may be a database record at the local end, or obtained from a cloud server or other device.

In some illustrative embodiments, in step S101, m first air conditioners of the same model as the second air conditioner are first acquired, where m is a positive integer less than or equal to n. If m is less than n, the nm first air conditioner is randomly obtained. If n is 100, first obtain the first air conditioner with the same temperature as the first temperature of the second air conditioner in the database. If the first air conditioner in the current database meets the condition is only 60, then the remaining The 40 units randomly acquire the first air conditioner whose set temperature is the first temperature in the database. Further, the m first air conditioner is the same as the second air conditioner, and the power correction coefficient α _i =1. In the above embodiment, the first air conditioner of the same model as the second air conditioner is preferentially obtained in the database to ensure that the operating environment of the extracted first air conditioner is closest to the second air conditioner, thereby improving the accuracy of the estimated power consumption.

In order to give a specific description of the above embodiments, FIG. 2 is a schematic flowchart diagram of a method for estimating power consumption of an air conditioner according to an embodiment of the present invention. As shown in FIG. 2, the method includes:

Step S201, according to the power saving control scheme, the set temperature of the user air conditioner is adjusted from T11 to T12;

Step S202, according to the reported power, calculate the actual power consumption W2 of the user air conditioner in the T time period, such as 10:00-11:00;

According to the reported power, the data obtained is as follows:

P ₁ =700W, 10min; P ₂ =1000W, 20min; P ₃ =800W, 15min; P ₄ =600W, 15min;

According to formula 6,

Where m=4,

Calculate W2 = 48 KW·min = 2880 * 10 ³ J.

Step S203, collecting operation data of a plurality of air conditioners with the set temperature T11 in the same area, and calculating the estimated power consumption W1;

Considering that the number of the same model in a certain area will vary, we require collecting 100 air conditioners in the same area to estimate the power consumption at T11 temperature. Priority is given to the same type of air conditioner. When the same type of air conditioner is not enough, 100 sets are randomly selected. The power consumption W1 at the T11 temperature is estimated based on the weighted average of the power consumption of the 100 devices.

Among them, the specific calculation method of W1 is as follows:

The calculation method of the power consumption of each first air conditioner is the same as that of Equation 6. The first air conditioner in the same area has n units in the T time, wherein n=100, and the respective running times are t _ix , n=1, 2,...,n ;x=1,2,...,s, and

Wherein, the correction power of each first air conditioner is

When m=n, that is, m=100, α _i =1, 100 units are calculated, and the average corrected power of the first air conditioner

When m<100, the coefficient correction is performed according to the corresponding energy consumption level and the number of horses, and 100 units are calculated, and the average corrected power of the first air conditioner is calculated.

Finally, based on the calculated

Calculate the estimated power consumption W1:

Step S204, calculating the power saving amount of 10:00-11:00 according to the estimated power consumption W1 and the actual power consumption W2 of the user air conditioner.

The correction factor refers to Table 1. Table 1 records the average unit energy consumption of the same number of devices with the same energy consumption level in the past year.

For example, the air conditioner of a user in a certain area is 1p, the second-level energy consumption, which is operated by T11 to T12 for 1 hour. In this area, the same type of air conditioner is set at T11 temperature within this hour. There are 60 units, the correction coefficient α _1-60 =1 of these 60 units, and the remaining 40 units are extracted by other types of air conditioners set at T11 temperature within 1 hour, assuming that all of us pumped 1p, For level 1 energy consumption, the correction factor for these 40 units is α _61-100 = A12/A11.

The estimated power consumption W1 of the user air conditioner at the set temperature of T11 is:

The above embodiment provides a specific implementation manner of the method for estimating the power consumption of the air conditioner according to the present invention. In the above embodiment, according to the model of the 100 first air conditioners and the first air conditioners, the first air conditioner is between 10:00 and 11:00. The operating parameters are calculated, and the second air conditioner is calculated, that is, the estimated power consumption of the user air conditioner at 1 hour from 10:00 to 11:00. Compared with the way of calculating the experimental data in the prior art, the power consumption of the air conditioner converted by the embodiment is more accurate.
