Number in FIG. 2

All are temperature sensors, and can be used in a capability calculation model, and can be a part of the capability calculation model, and the capability calculation model is selected according to the precision requirement, wherein W: the capacity calculation model is used for a compressor power acquisition device.

As shown in fig. 3, the air conditioner may be connected to an external server, such as a cloud server, a PC, a mobile phone, or a cloud platform, through WiFi (Wireless Fidelity) to implement an analysis processing function of the internet of things big data.

As shown in fig. 1, a method for controlling an air conditioner according to a first embodiment of the present application includes the following steps:

s1, periodically obtaining the current capacity output value and the current room load of the air conditioner.

It should be noted that, since the capacity output value (corresponding to the cooling capacity or the heating capacity) of the air conditioner operating in different states (such as a cooling state or a heating state), different working conditions, and different times is not always consistent with the nameplate and the laboratory test data, the current capacity output value of the air conditioner needs to be periodically obtained.

And S2, calculating to obtain the current predicted heating and cooling effect and the current predicted power consumption according to the current capacity output value and the current room load.

And S3, controlling the air conditioner according to the current predicted temperature rising and falling effect and the current predicted power consumption.

According to one embodiment of the application, periodically acquiring the current room load comprises: periodically acquiring room information, current indoor temperature, current outdoor environment temperature and indoor set temperature; and calculating to obtain the current room load according to the room information, the current indoor temperature, the current outdoor environment temperature and the indoor set temperature.

Specifically, when the air conditioner is powered on and in a standby state, the display panel of the air conditioner prompts a user to input or select room information installed in the air conditioner through a PC or a mobile phone, such as a region, a room area, a room floor height, a window size, a window orientation, a door size, a room building basic structure and material, a resident population in a room, and the like, and stores the input room information in a cloud server or a storage device of the air conditioner, such as a memory, for later calling after confirmation.

When the air conditioner needs to be used, a user sends a starting-up instruction through a remote controller to control the air conditioner to start up, and sets information such as running time and wind speed (if the user does not set the wind speed and the like, the default information such as the wind speed and the like during starting up is the wind speed and the like during last shutdown), and at the moment, a signal prompting lamp or information is adopted to prompt the user that the currently predicted temperature rising and falling effect (temperature rising or falling effect) T is | Tn-Tn0| and the currently predicted power consumption Qd is in calculation. Wherein Tn is the real-time indoor temperature, and Tn0 is the indoor temperature when the air conditioner is turned on.

When the air conditioner receives a starting instruction, the initial room load Qr0 is calculated according to the called room information stored in the memory or the cloud big data, the collected current indoor temperature, the current outdoor environment temperature, the indoor set temperature and the number of people when the air conditioner is started.

It should be noted that, in other embodiments of the present application, the initial room load Qr0 can be estimated per square meter according to the room information.

Then, the estimated temperature rise and fall effect and the estimated power consumption are estimated. Specifically, the air conditioner calls the historical capacity output value or the correction capacity, the energy efficiency, the power consumption, the air volume information of the air conditioner and the calculated initial room load Qr0 stored in the memory or the cloud big data, then calculates the initial predicted temperature rise and fall effect T0 and the initial predicted power consumption Qd0 of temperature reduction or temperature rise, and prompts the results to a user through a display panel, so that the user can visually see the initial predicted temperature rise and fall effect and the initial predicted power consumption.

After the above calculation and prompt are completed, the air conditioner starts to operate. The air conditioner is started to operate according to a preset comfortable temperature Tss or a maximum settable temperature or a difference value between the preset comfortable temperature and the current indoor temperature, the air conditioner with the structure of the figure 2 operates, and the air conditioner uses the structure of the figure 2

And the equal temperature sensor and the W compressor power acquisition device acquire and provide the acquired and provided power to a self calculation module according to a certain frequency, or provide the acquired and provided power to a server, a PC (personal computer), a cloud platform and the like, calculate the current capacity output value of the air conditioner in actual operation, record the current capacity output value as Qi and store the current capacity output value. Wherein i is a positive integer of 1, 2, 3 ….

Then, the air conditioner calls the room information stored in the memory or in the cloud big data, and recalculates the collected current indoor temperature, the current outdoor environment temperature, the indoor set temperature, the number of people and the like to obtain the current room load Qri, and stores the current room load Qri.

Then, the calculation module or the big data cloud platform of the air conditioner corrects and stores the predicted temperature-lowering or temperature-raising effect obtained by the last calculation and the power consumption obtained by the last calculation according to the current capacity output value Qi, the energy efficiency and the air volume information of the air conditioner and the current room load Qri obtained by calculation, and prompts the user of the current predicted temperature-lowering effect Ti ═ Ti-Tn0|, and the current predicted power consumption Qdi, so as to ensure the accuracy of the provided information. Wherein, Ti is the current indoor temperature.

And comparing and judging the current predicted temperature rise and drop effect Ti and the current predicted power consumption Qdi of the air conditioner, the current predicted temperature rise and drop effect Ti-1 calculated and stored last time and the current predicted power consumption Qdi-1 calculated and stored last time at intervals of T2, and controlling the air conditioner according to the judgment result.

According to an embodiment of the application, control the air conditioner according to present prediction temperature effect and present prediction power consumption, include: judging whether the current predicted heating and cooling effect at the last time is larger than the current predicted heating and cooling effect at the last time or whether the current predicted power consumption at the last time is larger than the current predicted power consumption at the last time; and if so, controlling the air conditioner to maintain the current running state.

Further, if not, judging whether the current capacity output value at the last time is equal to or greater than the current capacity output value; and if the last current capacity output value is equal to or greater than the current capacity output value, the running wind speed of the indoor fan in the air conditioner and/or the running frequency of the compressor are/is increased.

That is, if the judgment result is Ti-1 > Ti or Qdi-1 > Qdi, the air conditioner continues to control and maintain the current operation state to ensure the output of the current real-time capability; if the judgment result does not satisfy Ti-1 > Ti or Qdi-1 > Qdi, that is, Ti-1 is not more than Ti or Qdi-1 is not more than Qdi, the current capability output value Qi of the current time is further compared and judged with the current capability output value Qi-1 which is calculated and stored last time.

If Qi-1 is more than or equal to Qi, the air conditioner controls the running air speed of the indoor fan to be increased, or controls the running frequency of the compressor to be increased, or simultaneously controls the running air speed of the indoor fan and the running frequency of the compressor to be increased so as to improve the output of the current real-time capacity; if not, the current outdoor environment temperature Twi is further compared and judged with the current outdoor environment temperature Twi-1 collected and stored last time, namely Qi-1 is less than Qi.

Further, the control method of the air conditioner further includes: periodically acquiring the current outdoor environment temperature; if the last current capacity output value is smaller than the current capacity output value, judging whether the last current outdoor environment temperature is equal to or larger than the current outdoor environment temperature; and if the last current outdoor environment temperature is equal to or greater than the current outdoor environment temperature, controlling the air conditioner to maintain the current running state, or increasing the indoor set temperature when the air conditioner is in a cooling mode, or reducing the indoor set temperature when the air conditioner is in a heating mode.

Furthermore, if the last current outdoor environment temperature is lower than the current outdoor environment temperature, the running wind speed of the indoor fan in the air conditioner and/or the running frequency of the compressor are/is increased.

That is, when Qi-1 < Qi, the current outdoor environment temperature Twi of the time is further compared and judged with the current outdoor environment temperature Twi-1 collected and stored last time. If Twi-1 is more than or equal to Twi, the air conditioner can be controlled to keep running in the current state, or if the current mode is a refrigeration mode, the set indoor temperature is controlled to be increased; if the current mode is the heating mode, the indoor set temperature is controlled to be reduced, so that the purpose of energy conservation is achieved.

If Twi-1 is less than Twi, the air conditioner controls the running wind speed of the indoor fan to be properly increased, or controls the running frequency of the compressor to be properly increased, or simultaneously controls the running wind speed of the indoor fan and the running frequency of the compressor to be properly increased so as to improve the output of the capacity.

After the air conditioner executes the control logic, whether the running time set by a user is reached or the air conditioner is shut down when reaching the temperature or a shutdown instruction is received needs to be judged, and the fact that the temperature control is effective after the current capacity output of the behavior set by the user is adjusted is ensured. If yes, stopping the machine; if not, judging whether the current indoor temperature Tni exceeds a comfortable temperature threshold Tsf line or not. Wherein the comfort temperature threshold Tsf is in the preferential range of 24-26 ℃ for refrigeration and 22-24 ℃ for heating.

If the current indoor temperature Tni exceeds a comfortable temperature threshold Tsf line, namely if the current refrigeration mode judges that Tni is not more than Tsf, the air conditioner automatically increases the indoor set temperature, or if the current heating mode judges that Tni is not more than Tsf, the air conditioner automatically decreases the set temperature in the house, then the current capacity output value Qi of the air conditioner and the current room load Qri are continuously acquired and calculated, the current predicted temperature rising and falling effect Ti and the current predicted power consumption Qdi are corrected and compared, and the next cycle is started until the condition is met, and the air conditioner is stopped.

If the current indoor temperature Tni does not exceed the comfortable temperature threshold Tsf line, namely if the current indoor temperature Tni is judged to be greater than Tsf in a refrigeration mode, or if the current indoor temperature Tni is judged to be less than Tsf in a heating mode, directly and continuously acquiring and calculating the current capacity output value Qi of the air conditioner and the current room load Qri, correcting and comparing the current predicted temperature rising and falling effect Ti and the current predicted power consumption Qdi, and entering the next cycle until the condition is met and stopping.

In summary, the present application mainly uses a current capacity output value and a cloud computing technology based on a traditional PID target temperature control, and preferentially calculates an initial room load at the room starting time according to room information obtained by interaction with a user before the air conditioner is started and collected information, calls data such as air volume, historical capacity energy efficiency and power consumption of the air conditioner stored in a memory of the air conditioner or cloud big data, calculates an initial predicted temperature rise and fall effect and initial predicted power consumption, and informs the user of the initial predicted temperature rise and fall effect and the initial predicted power consumption. And then normally starting operation, firstly operating according to the current indoor temperature and a preset comfortable temperature Tss or a maximum settable temperature PID approximation algorithm, correcting the predicted temperature rise and fall effect and the predicted power consumption of temperature reduction or temperature rise according to the current real-time capacity energy efficiency and the current real-time room load of the air conditioner at a certain time interval in the operation process, comparing and judging the predicted temperature rise and fall effect and the predicted power consumption before and after correction, and then controlling the air conditioner according to the judgment result, thereby solving the technical problems of inaccurate control and untimely response caused by the room temperature as a single control quantity and the hysteresis characteristic thereof, and realizing more timely and accurate control and energy-saving and moderate effect by directly adopting the current capacity output value and the current room load for prejudgment control.

According to an embodiment of the present application, after controlling the air conditioner according to the current predicted temperature rising and dropping effect and the current predicted power consumption, the method further includes: providing control suggestions to a user; judging whether a setting instruction of a user is received or not; if so, stopping controlling the air conditioner according to the current predicted temperature rising and falling effect and the current predicted power consumption, and controlling the air conditioner according to a set instruction; if not, the air conditioner is continuously controlled according to the current predicted temperature rising and falling effect and the current predicted power consumption.

Specifically, in the operation process of the air conditioner, the current predicted heating and cooling effect and the current predicted power consumption of the air conditioner are obtained again at intervals of T2, and the current predicted heating and cooling effect Ti and the current predicted power consumption Qdi obtained this time are compared and judged with the last current predicted heating and cooling effect Ti-1 and the last current predicted power consumption Qdi-1 respectively.

If Ti-1 > Ti or Qdi-1 > Qdi, a green light or a normal operation icon is displayed on the control panel of the air conditioner, the user is prompted to keep the current operation state, and the user is given a choice to judge whether to change the setting. If the user changes the setting state through the remote controller, namely the user sends out a setting instruction through the remote controller and is received by the air conditioner, the air conditioner operates according to the setting changed by the user; if the user does not set or the air conditioner does not receive the setting instruction, namely the current provided suggestion is adopted by the user by default, a green light or a normal operation icon is displayed, and the current state operation is continuously kept so as to ensure the output of the current real-time capability.

If Ti-1 is less than or equal to Ti or Qdi-1 is less than or equal to Qdi, the current capability output value Qi is further compared and judged with the last current capability output value Qi-1.

If Qi-1 is larger than or equal to Qi, the air conditioner controls a display panel to display a yellow light or a certain icon, the yellow light or the certain icon is provided for a user, meanwhile, the user is reminded of green life, the running wind speed of an indoor fan in the air conditioner is increased, or the running frequency of a compressor in the air conditioner is increased, or the running wind speed of the indoor fan and the running frequency of the compressor in the air conditioner are increased, the air inlets and air outlets on the indoor side and the outdoor side are kept smooth, and the user is given the option to judge whether the setting is changed. If the user changes the setting state and the air conditioner receives the setting state, the air conditioner operates according to the setting changed by the user; if the user does not set or the air conditioner does not receive the setting instruction, namely the user is acquiescently provided with the current suggestion, the rapid adjustment priority mode is executed, the current running wind speed of the indoor fan is actively improved, or the running frequency of the compressor is actively improved, or the running wind speed of the indoor fan and the running frequency of the compressor are simultaneously improved, so that the current real-time capacity output is improved.

If Qi-1 is less than Qi, the current outdoor environment temperature Twi and the last current outdoor environment temperature Twi-1 are further compared and judged.

If Twi-1 is larger than or equal to Twi, a yellow light or a certain icon is displayed on the air conditioner control display panel and is provided for a user, the user is reminded of closing doors and windows, frequent access is reduced, the current state operation can be kept, or when the air conditioner is in a cooling mode, the user is reminded of increasing indoor set temperature and reducing the use of heating electric appliances, or when the air conditioner is in a heating mode, the user is reminded of reducing the indoor set temperature, and the user is given to select and judge whether to change the setting. If the user changes the setting state and the air conditioner receives the setting state, the air conditioner operates according to the setting changed by the user; if the user does not set or the air conditioner does not receive a setting instruction, namely the user is acquiescently provided with the current suggestion, a healthy energy-saving priority mode is executed, wherein if the current refrigeration mode is adopted, the background automatically increases the indoor set temperature; or if the current mode is the heating mode, the background automatically reduces the indoor set temperature to achieve the purpose of energy conservation; alternatively, the comfort priority mode is executed, keeping the current state unchanged.

If Twi-1 is less than Twi, the air conditioner controls the display panel to display a yellow light or a certain icon to provide the yellow light or the icon for the user, meanwhile, the user is reminded of green life, please close doors and windows, reduce frequent access, properly improve the running air speed of an indoor fan in the air conditioner, or properly improve the running frequency of a compressor in the air conditioner, or properly improve the running air speed of the indoor fan in the air conditioner and the running frequency of the compressor, if the air conditioner is in a refrigeration mode, the user is additionally reminded of reducing the use of a heating electric appliance, and the user is given to select and judge whether to change the setting. If the user changes the setting state and the air conditioner receives the setting state, the air conditioner operates according to the setting changed by the user; if the user does not set or the air conditioner does not receive the setting instruction, namely the user is acquiescently provided with the current suggestion, the rapid adjustment priority mode is executed, the running wind speed of the indoor fan is actively improved, or the running frequency of the compressor is actively improved, or the running wind speed of the indoor fan and the running frequency of the compressor are actively improved at the same time, so that the current real-time capacity output is improved.

Further, after the air conditioner executes the control logic, whether the running time set by a user is reached or the air conditioner is shut down when the running time meets the temperature, or a shutdown instruction is received, and the temperature control is effective after the current capacity output of the user-set behavior is adjusted. If yes, stopping the machine; if not, judging whether the current indoor temperature Tni exceeds a comfortable temperature threshold Tsf line or not.

If the current indoor temperature Tni exceeds a comfortable temperature threshold Tsf line, namely if the current refrigeration mode judges that Tni is not more than Tsf, reminding a user that the current indoor temperature is too low, and please increase the indoor set temperature, or if the current heating mode judges that Tni is not less than Tsf, reminding the user that the current indoor temperature is too high, and asking for reducing the indoor set temperature, and giving the user a choice to judge whether to change the setting.

In addition, after the air conditioner calculates and displays the current predicted temperature rising and dropping effect and the current predicted power consumption to the user, the user can also make related decisions according to the intuitive current predicted temperature rising and dropping effect and the current predicted power consumption so as to actively control the air conditioner and improve the satisfaction degree of the user.
