[0055] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0056] First, refer to Figure 1 The embodiment of the present invention provides a rotation control method of an air conditioner, which includes:

[0057] S1. Divide the internal space of the building into regions according to the acquired energy-saving signal and the power of each target indoor unit of the air conditioner to obtain at least two sub-regions; wherein each sub-region corresponds to at least one target indoor unit;

[0058] S2. Collecting environmental parameters in the corresponding sub-area according to the internal machine target, and obtaining a temperature change curve corresponding to each sub-area according to the environmental parameters;

[0059] S3. Calculate the predicted duration of each sub-area based on the preset comfort temperature threshold and temperature change curve

[0060] S4. According to the predicted duration, the target indoor units corresponding to one of the sub-partitions are adjusted to the corresponding working state in sequence according to a preset order, while the target indoor units corresponding to the remaining sub-partitions maintain the original operating state, so that the energy consumption of the air conditioner meets the requirements of the energy-saving signal.

[0061] The rotation control method provided by the present invention can divide all indoor units into individually controllable sub-divisions according to energy-saving signals and the actual power of each indoor unit of the air conditioner, and control the target indoor units of the air conditioner corresponding to each sub-division in turn according to the comfortable temperature threshold and the predicted duration, so as to reduce energy consumption while ensuring the user's temperature requirements. Specifically, the method can first obtain the area covered by the air conditioner, and divide at least two sub-divisions based on the power of each target indoor unit of the air conditioner and the amount of energy required to be reduced by the energy-saving signal, and ensure that there is at least one target indoor unit in each sub-division. The method can also collect environmental parameters in the corresponding sub-division through the target indoor unit to calculate and obtain the temperature change curve of the sub-division corresponding to the target indoor unit, so as to judge the expected time required for the corresponding sub-division to reach the expected comfort temperature threshold after turning off all the target indoor units in the sub-division through the temperature change curve and the preset comfort temperature threshold. The method further adjusts the working states of all target indoor units contained in each sub-partition in sequence according to a preset order, and keeps the target indoor units of the remaining sub-partitions whose working states have not been adjusted in the original operating states; through this method, the present invention obtains the environmental parameters of different locations in the area covered by the air conditioner based on each target indoor unit of the air conditioner, realizes the accurate prediction of the temperature change state in each sub-partition, and at the same time uses the upper limit temperature of comfort corresponding to user needs as a measurement standard, and controls each sub-partition in turn, so as to realize the effective control of energy consumption.

[0062] In some specific embodiments, the comfort temperature threshold includes an upper and lower comfort temperature limit, and the temperature change curve includes a temperature rise curve and a temperature drop curve. The method can determine the predicted heating time for the target area to rise to the upper comfort temperature limit based on the temperature rise curve, and can also determine the predicted cooling time for the target area to drop to the lower comfort temperature limit based on the temperature drop curve, and then adjust the target indoor unit in the sub-division corresponding to the target area to the off state according to the predicted heating time, or adjust the target indoor unit in the sub-division corresponding to the target area to the on state according to the predicted cooling time. Specifically, the method can keep the target indoor unit in the off state within the predicted heating time, so that the temperature will not exceed the upper comfort temperature limit when it is turned on again. It can also keep the target indoor unit in the on state within the predicted cooling time, so that the temperature will not exceed the lower comfort temperature limit when it is turned off again. Thereby, the temperature of each indoor area is kept within the limited range of the comfort temperature threshold.

[0063] In some specific implementations, the energy-saving signal may be a peak-shaving signal output by an aggregator, wherein the peak-shaving signal includes a peak-shaving amount. The method may divide regions by the peak-shaving amount and the power of the target indoor machine in the region.

[0064] In some specific implementations, the method can control the target indoor units corresponding to multiple sub-partitions to shut down according to energy-saving signals (peak shaving signals), while the target indoor units corresponding to the remaining sub-partitions maintain their original operating states. Specifically, the method can pre-divide all target indoor units into sub-partitions according to the preset target power value, and select and rotate the sub-partitions according to the energy-saving signal to achieve energy control in the air conditioner. Specifically, the method can preset the target power value to be 3KW, and divide all target indoor units into a sub-partition with a sum of 3KW power. When the peak shaving amount corresponding to the obtained peak shaving signal is 0-3KW, the method needs to control the target indoor units corresponding to one sub-partition to shut down in sequence according to the preset order, while the remaining sub-partitions maintain their original operating states. When the peak shaving amount is 3-6KW, the method needs to control the target indoor units corresponding to two sub-partitions to shut down at the same time in sequence according to the preset order, while the remaining sub-partitions maintain their original operating states.

[0065] In some specific implementations, when the target indoor machine in the sub-partition resumes working, the method can obtain the working power before the target indoor machine is shut down, and control the target indoor machine in the sub-partition to work with the working power before shutting down. The preset order can be randomly generated according to the number of sub-partitions, or can be generated according to the building area of ​​the sub-partition.

[0066] In some embodiments, reference Figure 2 Before dividing the internal space of the building into regions according to the acquired energy-saving signal and the power of each target indoor unit of the air conditioner to obtain at least two sub-regions, the method further includes:

[0067] S11, obtaining a first temperature change value of all indoor units of the air conditioner within a preset time;

[0068] S12, screening out indoor units to be controlled whose first temperature change values ​​are outside a preset temperature change range;

[0069] S13, control the indoor unit to be controlled to be in the on state.

[0070] This method can classify all the indoor units of the air conditioner to achieve differentiated control of different indoor units, thereby meeting the temperature requirements of the user. Specifically, this method will record the temperature change value of the indoor unit of the air conditioner within a preset time to obtain a first temperature change value. When the first temperature change value is outside the preset temperature change range, this method can determine that the temperature of the area covered by the indoor unit corresponding to the current first temperature change value is unstable, or does not meet the temperature requirements required by the user, and then use this part of the indoor units as the indoor units to be controlled, so that the indoor units to be controlled continue to remain in the turned-on state, and realize the temperature control of the area corresponding to the indoor units to be controlled, so that the temperature reaches the set temperature of the indoor units to be controlled before accepting the rotation control method provided by the present invention.

[0071] In some embodiments, reference Figure 3 , screening out the indoor units to be controlled whose first temperature change value is outside the preset temperature change range, further comprising:

[0072] S121, real-time monitoring of a second temperature change value of the indoor unit to be controlled within a preset time;

[0073] S122: When the second temperature change value is within the temperature change interval, the indoor unit to be controlled is included in the target indoor unit.

[0074] The rotation control method provided by the present invention can also determine whether the temperature set by the user is reached in the corresponding area according to the temperature change of the indoor unit to be controlled, and perform rotation control on the indoor unit to be controlled when the corresponding area has reached the set temperature. Specifically, the method can detect the second temperature change value of the corresponding area of ​​the indoor unit to be controlled within a preset time; when the second temperature change value is within the temperature change interval, the method can determine that the corresponding area of ​​the current indoor unit to be controlled has reached the set temperature, and include the indoor unit to be controlled in the target indoor unit, so that the original indoor unit to be controlled can participate in the rotation control method provided by the present invention. Through this method, the present invention can keep the user's temperature demand at a higher priority, control the indoor units in the area covered by the air conditioner, and improve the user experience.

[0075] In some embodiments, reference Figure 4, the internal space of the building is divided into regions according to the acquired energy-saving signal and the power of each target indoor unit of the air conditioner, and at least two sub-regions are obtained, including:

[0076] S14, obtaining a regional power range obtained by an energy-saving signal;

[0077] S15. Divide the target internal machines one by one to obtain at least two sub-areas, so that the sum of the power of each target internal machine is within the regional power range.

[0078] The rotation control method provided by the present invention can group the target indoor units of the air conditioner according to the energy consumption requirements of the energy-saving signal to generate the minimum control unit for control, that is, the sub-partition. Specifically, the method can obtain the energy-saving signal, generate the regional power interval according to the energy-saving signal board, and divide the target indoor units one by one according to the regional power interval to obtain at least two sub-partitions, and make the sum of the power of the target indoor units contained in the sub-partitions within the regional power interval. For example: when the regional power interval corresponding to the energy-saving signal is 5KW±0.2KW, the method accumulates the power of each indoor unit one by one. When the sum of the accumulated power is within the range of 5KW±0.2KW, the corresponding indoor units are used as the target indoor units of the first sub-partition, and the second sub-partition is divided again according to the above process, and so on, until all the indoor units of the air conditioner are divided. Through this method, the invention provides a minimum control unit of the rotation control method, so that the method can realize rotation control according to each sub-partition.

[0079] In some embodiments, reference Figure 5 , collect the environmental parameters of the corresponding sub-area according to the target internal machine, and obtain the temperature change curve corresponding to each sub-area according to the environmental parameters, including:

[0080] S21, according to the environmental parameters in the corresponding sub-area collected by the target indoor unit and the preset target indoor unit working efficiency, multiple fittings are performed to obtain the heat transfer capacity value and the ventilation capacity value;

[0081] S22, calculating the heat transfer capacity value and the ventilation capacity value according to a preset heat balance formula to obtain the indoor air heat capacity value;

[0082] S23. Generate a temperature change curve corresponding to each sub-area according to the heat transfer capacity value, the ventilation capacity value, the indoor air heat capacity value and preset parameters.

[0083] This method can predict the temperature rise state of the corresponding area in the sub-zone in the future period of time based on the corresponding environmental parameters in the sub-zone. Specifically, this method collects the environmental parameters in the corresponding sub-zone and the working efficiency of the target indoor machine according to the target indoor machine, and generates more accurate heat transfer capacity value and ventilation capacity value by multiple fitting. Then, the obtained values ​​are calculated by the heat balance formula to obtain the indoor air heat capacity value, and the temperature change curve corresponding to each sub-zone is constructed according to the heat transfer capacity value, ventilation capacity value, indoor air heat capacity value and preset parameters.

[0084] In some specific embodiments, the method adopts the formula Qcool=kA*ΔT+1.293*F*Δh / 3600 to achieve multiple fitting of kA and F (where kA is the heat transfer capacity value, F is the ventilation capacity value, and Qcool is the target indoor unit working efficiency). Environmental parameters include ΔT (indoor and outdoor air temperature difference) and Δh (indoor and outdoor air specific enthalpy difference). ΔT can be obtained by the target indoor unit multiple times at different time intervals to obtain multiple groups of ΔT, and kA and F are fitted multiple times according to the multiple groups of ΔT to obtain accurate kA and F. Δh is a constant preset in the method, which is generally obtained from engineering experience.

[0085] Furthermore, according to the heat balance formula This method can obtain the indoor air heat capacity value (cm2) by the obtained heat transfer capacity value and ventilation capacity value. Wherein, T is the temperature after a period of time, T0 is the outside temperature value, τ is the time variable, ε is the constant coefficient, and in the present invention, ε=ln(T0-T1), and T1 is the initial temperature when the indoor power is turned off. In addition, this method can also obtain the indoor air volume (V) by the indoor air heat capacity value (cm2), that is, the indoor air volume V=cm2 / (1.005*1.293).

[0086] Furthermore, according to the above formula After the indoor air heat capacity value (cm) has been determined, this method uses cm in the formula as a known parameter, combined with preset parameters, ventilation capacity value (F), and heat transfer capacity value (kA), to predict the temperature T after a period of time, and then provides a temperature change curve formula with τ as the time variable as the independent variable and the temperature T after a period of time as the dependent variable, and thus provides a temperature change curve.

[0087] In some embodiments, the predicted duration of each sub-area is calculated based on the preset comfortable temperature threshold and the temperature change curve, and the PMV (Predicted Mean Vote) value can be used as a measure of the comfortable temperature threshold, such as defining the PMV value between [-0.5, +0.5] as a comfortable area, and obtaining the comfortable temperature threshold in turn. The comfortable temperature threshold is used as the temperature T after a period of time, and the time variable τ is obtained, and τ is used as the predicted duration. The calculation method and application method of the PMV value are mentioned in the relevant technology, so it will not be repeated here.

[0088] In some embodiments, reference Figure 6 The working state includes an on state and an off state. According to the predicted duration, the target indoor unit corresponding to one of the sub-partitions is adjusted to the corresponding working state in a preset order, while the target indoor units corresponding to the other sub-partitions maintain the original operating state, so that the energy consumption of the air conditioner meets the requirements of the energy-saving signal, including:

[0089] S41, calculating the minimum predicted duration corresponding to the target internal machine in each sub-area, and obtaining the rotation control time of each sub-area;

[0090] S42, randomly selecting one of the sub-partitions;

[0091] S43, adjusting the target indoor machine corresponding to the target sub-partition to the corresponding working state according to the rotation control time corresponding to the selected sub-partition, and making the target indoor machines corresponding to the remaining sub-partitions maintain the original operating state;

[0092] S44, changing the working state of the target internal machine of the target sub-partition;

[0093] S45. Select the target internal machine corresponding to the next sub-partition according to the preset order until the rotation control of all sub-partitions is completed.

[0094] The rotation control method provided by the present invention can obtain the rotation control time of this sub-partition according to the minimum value of the predicted duration corresponding to all the target indoor machines in each sub-partition, and control the working state in the sub-partition according to the rotation control time and the preset order to meet the requirements of the energy-saving signal. Specifically, the method first obtains the predicted duration of the target indoor machine in each sub-partition, and obtains the rotation control time of this sub-partition according to the predicted duration. Further, the predicted duration includes the predicted heating duration and the predicted cooling duration. Through the predicted heating duration, the method randomly selects one of the sub-partitions, and starts the rotation control process with this sub-partition as the starting node of the rotation control method, so as to control the target indoor machine in this sub-partition to keep the shutdown state according to the rotation control time of this sub-partition. When the shutdown duration reaches the rotation control time of this sub-partition, the method can turn on the target indoor machine in this sub-partition, and select the next sub-partition according to the preset order to repeat steps S43 to S45 to realize the rotation control of all sub-partitions. Alternatively, by predicting the cooling time, the method randomly selects one of the sub-partitions, and uses this sub-partition as the starting node of the rotation control method to start the rotation control process, thereby controlling the target indoor unit in this sub-partition to remain turned on according to the rotation control time of this sub-partition. When the on time reaches the rotation control time of this sub-partition, the method can turn off the target indoor unit in this sub-partition, and select the next sub-partition in a preset order to repeat steps S43 to S45 to achieve rotation control of all sub-partitions. Through this method, the present invention can control each sub-partition in turn while minimizing the impact on the user's experience, thereby achieving rotation control of the air conditioner.

[0095] In some embodiments, S41 further includes:

[0096] According to the target internal machine working efficiency corresponding to each sub-partition, the target cooling time corresponding to each sub-partition is obtained;

[0097] According to the minimum predicted duration corresponding to each sub-partition, select the estimated rotation duration;

[0098] Select any sub-partition as the target sub-partition. If the sum of the estimated rotation durations corresponding to other sub-partitions except the target sub-partition is greater than the target cooling duration corresponding to the target sub-partition, the estimated rotation duration corresponding to the currently selected target sub-partition is used as the rotation control time of the target sub-partition.

[0099] In order to ensure that the rotation control method can be controlled in a preset order and repeatedly execute the rotation control method provided by the present invention, the present invention provides a specific setting method for the rotation control time. Specifically, the method first sorts out the working efficiency of the target indoor machine corresponding to each sub-partition, and calculates the target cooling time for cooling each sub-partition to the lower limit of the comfortable temperature under the target indoor machine working efficiency. Furthermore, the method preliminarily formulates the rotation control time of each partition for the minimum predicted time corresponding to each sub-partition, obtains the estimated rotation time corresponding to each sub-partition, and then verifies the feasibility of the rotation time corresponding to each sub-partition in the cyclic control process of the rotation control method, that is, selects any sub-partition as the target sub-partition, and makes the sum of the estimated rotation time corresponding to the remaining sub-partitions except the target sub-partition greater than the target cooling time of the target sub-partition, and regards each estimated rotation time that meets this condition as the rotation control time of the corresponding sub-partition, thereby realizing the cycle of the control method of the present invention. It can be understood that when each sub-partition is controlled in a cycle in a preset order, the estimated cooling time of the selected target sub-partition should be less than the sum of the estimated rotation times of other sub-partitions except the target sub-partition, so that when the target sub-partition is controlled to be in a shutdown state next time in the preset order, the temperature in the target sub-partition can be cooled to at least below the lower limit of the comfort temperature, thereby ensuring that the temperature can be maintained below the limited range of the comfort temperature threshold within the estimated rotation time of the target sub-partition, thereby ensuring the user experience.

[0100] In some specific implementations, the PMV (Predicted Mean Vote) value may be used as a measure of the lower limit of the comfortable temperature. For example, the PMV value between [-0.5, +0.5] is defined as a comfortable area, and the lower limit of the comfortable temperature is obtained accordingly.

[0101] In some specific implementations, the present invention provides six sub-partitions, which are named as the first sub-partition to the sixth sub-partition in a preset order. This method selects a sub-partition at random, such as the first sub-partition as the target sub-partition, and then takes the minimum predicted duration of all internal machines in the first sub-partition as the setting standard for the estimated rotation duration, and so on, obtains the estimated rotation duration τ corresponding to each of the first sub-partition to the sixth sub-partition 1 to τ 6 , where the estimated rotation time τ 1 Corresponding to the first sub-partition, estimated rotation duration τ 2 Corresponding to the second sub-area, and so on, the target cooling time t of the first sub-area selected at random is 1 Less than the estimated rotation duration τ corresponding to the second to sixth sub-partitions 2 to τ 6 The sum of 1 to τ6 Each of them can satisfy the above conditions, and the τ that satisfies the above conditions 1 to τ 6 As the rotation control time corresponding to the first sub-partition to the sixth sub-partition.

[0102] In some other embodiments, the method can obtain the working efficiency of the target indoor unit before it is shut down after the rotation control time of the target indoor unit corresponding to the control sub-partition ends, and control the target indoor unit to continue to work at the working efficiency before it is shut down, so as to ensure that in the process of rotation control in a preset order, the area corresponding to the target indoor unit is always between the lower limit of the comfort temperature and the comfort temperature threshold.
