[0035] Step 101: Collecting operation data of a multi-split air conditioner;

[0036] Step 102: Screening the operation data, and determining a power adjustable region by using the screened operation data;

[0037] Step 103: Adjusting the power of the multi-split air conditioner according to the power adjustable region.

[0038] The embodiment can be applied to a multi-split air conditioner system, that is, a central air conditioning system including one main unit and multiple indoor units of multiple rooms. Of course, in addition to the multi-split air conditioner, the embodiment can also be applied to a water-cooled air conditioning system.

[0039] The embodiment collects operation big data of a multi-split air conditioner, screens the collected operation data, filters out abnormal values that may occur in air conditioner operation, considers the adjustable interval of the operation power of the multi-split air conditioner under the condition of meeting the user comfort, and adjusts based on the adjustable interval, so as to ensure the thermal comfort requirement of the user and ensure the use experience of the user.

[0040] The embodiment can establish a multi-split air conditioner power adjustable interval model considering user thermal comfort.

[0041] The operation data in the embodiment can include: operation power of an outdoor unit, outdoor environment temperature, on-off state of each indoor unit, operation mode of each indoor unit, indoor environment temperature of a room where each indoor unit is installed, average value of the number of on indoor units and the indoor environment temperature of the on room. The operation mode of the indoor unit includes a cooling operation mode and a heating operation mode.

[0042] In an embodiment, the screening of the operation data comprises:

[0043] Obtaining the operation mode in the operation data, and dividing the operation data according to the operation mode;

[0044] For each operation mode, removing the part of the operation data in which the indoor environment temperature exceeds a first preset range from the divided operation data, to obtain the screened operation data.

[0045] The embodiment screens the collected air conditioner operation data according to a certain indoor environment temperature range according to the relevant thermal comfort evaluation index, and screens the operation power of the outdoor unit, the outdoor environment temperature and the number of on indoor units that meet the indoor temperature thermal comfort index.

[0046] Here, the first preset range can be set according to the thermal comfort index. For example, in the cooling condition, the first preset range is selected as 24-28℃; in the heating condition, the first preset range is selected as 18-24℃; according to the air conditioner condition and the above indoor temperature interval, the outdoor unit running power, the outdoor environment temperature and the number of start-up units that meet the indoor temperature thermal comfort index are screened out.

[0047] In addition to setting the first preset range according to the thermal comfort index, the embodiment can also select different temperature intervals according to the actual use of different users; and other thermal comfort evaluation indexes such as PMV can also be selected.

[0048] In an embodiment, the screening of the running data includes:

[0049] The outdoor environment temperature and the outdoor unit running power in the running data are obtained.

[0050] The part of the running data in which the outdoor environment temperature is outside the preset first upper and lower limit percentage is removed; and / or, the part of the running data in which the outdoor unit running power is outside the preset second upper and lower limit percentage is removed, to obtain the screened running data.

[0051] The embodiment can further screen the running data according to the related screening conditions, and screen out the non-steady state points and abnormal value points in the air conditioner running. The specific screening method can be as follows:

[0052] 1. The air conditioner running data in which the outdoor environment temperature is higher than the first upper limit percentage and lower than the first lower limit percentage is screened out.

[0053] 2. The air conditioner running data in which the outdoor unit running power is higher than the second upper limit percentage and lower than the second lower limit percentage is screened out.

[0054] Here, the preset first upper and lower limit percentage and the preset second upper and lower limit percentage can be selected based on the situation. For example, the first upper and lower limit percentage is selected as 5%, and the second upper and lower limit percentage is selected as 5%. That is, the outdoor environment temperature higher than the first upper limit percentage and lower than the first lower limit percentage, and the outdoor unit running power higher than the second upper limit and lower than the second lower limit percentage are screened out.

[0055] The embodiment screens the collected running data, and can screen out the non-steady state points and abnormal value points in the air conditioner running.

[0056] In an embodiment, the determination of the power adjustable region by using the screened running data includes:

[0057] The screened running data is plotted in the form of a scatter plot with the outdoor environment temperature as the horizontal coordinate and the outdoor unit running power as the vertical coordinate.

[0058] For the scatter plot, a vertical line is drawn through the horizontal coordinate of the leftmost point as a first boundary, and a vertical line is drawn through the horizontal coordinate of the rightmost point as a second boundary;

[0059] The upper and lower bounds of the outdoor unit operating power of the scatter points in the scatter plot are fitted using a quadratic polynomial to obtain a third boundary and a fourth boundary;

[0060] The region enclosed by the first boundary, the second boundary, the third boundary, and the fourth boundary is determined as a power adjustable region.

[0061] According to the screened air conditioner operating data, a scatter plot is drawn with the outdoor environment temperature as the horizontal coordinate and the outdoor unit operating power as the vertical coordinate. Two lines are drawn through the outdoor environment temperatures at the first upper and lower percentages of the horizontal coordinate. For each outdoor environment temperature, the maximum and minimum operating powers corresponding thereto are found and fitted using a polynomial to obtain a polynomial fitting curve of the upper and lower bounds. The region enclosed by the above line segments is the adjustable interval of the outdoor unit operating power of the multi-split air conditioner.

[0062] In an embodiment, the power adjustment of the multi-split air conditioner according to the power adjustable region comprises:

[0063] Determining a corresponding power adjustable interval function according to the power adjustable region;

[0064] Determining the number of operating units of the multi-split air conditioner;

[0065] Determining the power adjustable interval function of each air conditioner based on the number of operating units and the power adjustable interval function.

[0066] The function of the adjustable interval of the outdoor unit operating power of the multi-split air conditioner obtained according to the power adjustable region of the multi-split air conditioner is: [P low , P high ] = f(T out , M on ).

[0067] Wherein, [P low , P high ] is the adjustable interval of the outdoor unit operating power of the multi-split air conditioner, unit: kW; P low is the lowest adjustable power, unit: kW; P high is the highest adjustable power, unit: kW; T out is the outdoor environment temperature, ℃; M on is the number of operating units.

[0068] Furthermore, depending on the number of units activated, in one embodiment, when the number of units activated is 2, the power adjustable range function is:

[0069] [P low P high ] = [0.00182*T out 2 -0.0959*T out +1.825, -0.00726*T out 2 +0.477*T out -4.936]

[0070] 25 <= Tout = 36

[0071] Among them, [P] low P high [P] is a power adjustable range function; low The minimum adjustable power; P high The maximum adjustable power; T out This refers to the outdoor ambient temperature.

[0072] When the number of units in operation is 3, the power adjustable range function is:

[0073] [P low P high ] = [0.00843*T out 2 -0.495*T out +7.865, -0.00878*T out 2 +0.607*T out -6.414]

[0074] 25<=T out <=39

[0075] Among them, [P] low P high [P] is a power adjustable range function; low The minimum adjustable power; P high The maximum adjustable power; T out This refers to the outdoor ambient temperature.

[0076] The power adjustment method provided in this invention involves collecting operating data from a multi-split air conditioner; filtering the operating data and determining the power adjustable range using the filtered data; and adjusting the power of the multi-split air conditioner according to the power adjustable range. This invention, by considering user-side thermal comfort requirements, filters the operating data and adjusts the power within the determined power adjustable range, thus ensuring user thermal comfort and a superior user experience.

[0077] The following will describe the solution of this embodiment in detail based on a practical application scenario.

[0078] See Figure 2 , Figure 2 This is a schematic diagram of an overall power regulation process provided in an embodiment of this application. The process includes:

[0079] Step S1: Collect operating data for the multi-split air conditioning system. This includes outdoor unit operating power, outdoor ambient temperature, number of indoor units in operation, indoor unit operating mode, indoor ambient temperature, and calculate the average indoor ambient temperature of the rooms where the units are operating.

[0080] Step S2: Based on relevant thermal comfort evaluation indicators, select the outdoor unit operating power, outdoor ambient temperature, and number of units that meet the indoor temperature thermal comfort indicators mentioned in the previous step;

[0081] Step S3: Further filter the data based on the first and second upper and lower bound percentages to remove unsteady points and outliers in the air conditioning operation data;

[0082] Step S4: Select outdoor ambient temperature as the x-axis and outdoor unit operating power as the y-axis to draw a scatter plot. Take the outdoor temperature corresponding to the first upper and lower bound percentages to draw the outdoor ambient temperature range. Use a polynomial to fit the upper and lower bounds of the operating power to obtain the adjustable power range. Obtain the function rate of the adjustable range based on the fitted polynomial.

[0083] The adjustment process in this embodiment is specifically as follows:

[0084] 1. Collect multi-split air conditioner operation data, including: data recording time, outdoor unit operating power, outdoor ambient temperature, on / off status of each indoor unit, operating mode of each indoor unit, and indoor ambient temperature of each room where the indoor unit is installed. Using the collected multi-split air conditioner operation big data, calculate the average outdoor unit operating power, outdoor ambient temperature, number of indoor units in operation, and indoor ambient temperature of each room with the units in operation for each recording time.

[0085] 2、According to the relevant thermal comfort index, in the cooling condition, the indoor environment temperature range is selected as 24-28℃; in the heating condition, the indoor environment temperature range is selected as 18-24℃; according to the air conditioning condition and the above indoor temperature range, the outdoor unit running power, the outdoor environment temperature and the number of start-up units that meet the indoor temperature thermal comfort index are screened out.

[0086] 3、The first upper and lower limit percentage is selected as 5%, and the second upper and lower limit percentage is selected as 5% to further screen the data, i.e. to screen out the outdoor environment temperature higher than the first upper limit percentage and lower than the first lower limit percentage, and the outdoor unit running power higher than the second upper limit and lower than the second lower limit percentage.

[0087] 4、Select a multi-split air conditioning system containing six indoor units, corresponding to different numbers of start-up indoor units, and plot the screened data in the form of a scatter plot, wherein the outdoor environment temperature is selected as the horizontal coordinate and the outdoor unit running power is selected as the vertical coordinate. According to the plotted scatter plot, select the first upper and lower limit to draw two lines perpendicular to the horizontal coordinate, select a quadratic polynomial to fit the power upper and lower limit, and obtain the adjustable interval of the outdoor unit running power of the multi-split air conditioning, as shown in the following Figure 3 . The area enclosed by the dotted line is the adjustable interval of the outdoor unit running power of the multi-split air conditioning under different outdoor environment temperatures. The outdoor unit running power adjustable interval diagram of starting 2 and 3 indoor units is shown in Figure 4 , Figure 5 .

[0088] According to the plotted diagram, the function of the outdoor unit running power adjustable interval of the multi-split air conditioning is obtained: [P low , P high ] = f(T out , M on ).

[0089] When the number of start-up units is 2,

[0090] [P low , P high ] = [0.00182*T out 2 -0.0959*T out +1.825, -0.00726*T out 2 +0.477*T out -4.936], 25 <= T out <= 36

[0091] Wherein, [P low , P high ] is the power adjustable interval function; P low is the lowest power that can be adjusted; P highThe maximum power is adjustable; T out This refers to the outdoor ambient temperature.

[0092] When the number of machines in operation is 3,

[0093] [P low P high ] = [0.00843*T out 2 -0.495*T out +7.865, -0.00878*T out 2 +0.607*T out -6.414],25<=T out <=39

[0094] Among them, [P] low P high [P] is a power adjustable range function; low The minimum adjustable power; P high The maximum power is adjustable; T out This refers to the outdoor ambient temperature.

[0095] 5. After obtaining the function for adjusting the operating power range of the multi-split air conditioner, when encountering problems such as power grid peak shaving, carbon emission reduction, carbon trading, and building load response, this function can be used to obtain the adjustment range of the operating power of the multi-split air conditioner under a certain number of units in operation and outdoor ambient temperature. By controlling the air conditioner, power adjustment can be achieved within the adjustable operating power range.

[0096] It should be noted that after adjusting the temperature range of the thermal comfort index, the thermal comfort evaluation index, the type of central air conditioning system, and the data filtering conditions in this embodiment, the size of the adjustable range of outdoor unit power may change, but this method can still provide the corresponding adjustable range of air conditioning unit operating power.

[0097] This embodiment filters out unsteady and outlier values ​​from the operating data of the multi-split air conditioner to ensure that all power values ​​within the final adjustable power range can be achieved through a specific control strategy. By considering user-side thermal comfort requirements, this embodiment ensures that load adjustment of the multi-split air conditioner does not affect the user experience. The final output of this embodiment is a function of the outdoor unit power adjustment range with respect to outdoor ambient temperature and the number of units in operation, which can be used to guide energy-saving control and load adjustment of the multi-split air conditioner.
