Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to an air conditioning energy-saving control method and system. Background Technology

[0002] As an electrical appliance, air conditioners require a large amount of electricity to achieve their superior cooling function. While the emergence of inverter air conditioners has reduced electricity consumption to some extent, their energy-saving effect is limited. Users cannot obtain the total power consumption and electricity usage of inverter air conditioners in real time, and can only achieve energy saving and emission reduction by using existing inverter technology.

[0003] As living standards improve, people are no longer satisfied with the traditional cooling and heating functions of air conditioners and have higher requirements for the interactivity of air conditioners, such as statistics on air conditioner running time and power consumption. Therefore, a method that can adjust the air conditioner frequency through user-defined parameters is urgently needed. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to propose an air conditioning energy-saving control method and system to enable interaction between user input parameters and air conditioning operating frequency.

[0006] Step S1: Obtain the user's expected power consumption and power consumption duration, and obtain the power consumption for each hour based on the expected power consumption and power consumption duration, and mark it as the first power.

[0007] Step S2: After the indoor temperature reaches the specified temperature, the first operating parameters of the outdoor unit and the second operating parameters of the indoor unit are obtained every hour. The current power of the air conditioner is calculated based on the first and second operating parameters and marked as the second power.

[0008] Step S3: Determine whether the first power is greater than the second power. If it is greater, maintain the current power of the air conditioner. If it is less, obtain the current time, confirm the adjustment period according to the current time, and obtain the outdoor temperature change during the adjustment period according to the pre-configured first information mapping table. The first information mapping table is a mapping table of the relationship between time period and temperature change.

[0009] Step S4: Adjust the power of the outdoor unit or indoor unit of the air conditioner according to the change in outdoor temperature.

The compressor's energy consumption is used as the second operating parameter. The simulation model is a model of the air conditioning system established using thermodynamic and electrical principles.

[0015] Preferably, before calculating the second power, the following steps also need to be performed:

[0016] The first temperature inside the outdoor unit of the air conditioner is obtained, and it is determined whether the first temperature is higher than the first temperature threshold. If it is higher, the first operating parameter is corrected using the trained neural network.

[0017] The formula for correcting the first operating parameter is as follows:

[0018] ;

[0019] ;

[0020] ;

For activation function, Let be the weight of the first temperature in the j-th hidden layer. Let the weight be the weight of the first running parameter in the j-th hidden layer. It is the input of the input layer. For the first temperature, For the first running parameter, It is the bias of neurons in the hidden layer.

[0024] in , and These are the proportionality coefficients, For the first running parameter, C represents the second operating parameter, and C represents other conventional energy consumption.

[0025] Preferably, the specific steps of step S4 are as follows:

[0026] The difference between the outdoor temperature and the specified temperature is obtained as the first temperature difference. It is then determined whether the first temperature difference is less than the second temperature threshold. If it is not less than the second temperature threshold, the current power of the air conditioner is maintained. If it is less than the second temperature threshold, the required refrigerant flow rate of the indoor unit of the air conditioner is obtained through the first temperature difference.

[0027] The motor speed of the compressor is adjusted according to the flow rate of the refrigerant;

[0028] The fan of the outdoor unit of the air conditioner is adjusted based on the motor speed of the compressor after adjustment.

[0040] The judgment module is used to determine whether the first power is greater than the second power. If it is greater, the current power of the air conditioner is maintained. If it is less, the current time is obtained, the adjustment period is determined according to the current time, and the outdoor temperature change during the adjustment period is obtained according to the pre-configured first information mapping table. The first information mapping table is a mapping table of the relationship between the time period and the temperature change.

[0041] The adjustment module is used to adjust the power of the outdoor unit or indoor unit of the air conditioner according to the change in outdoor temperature.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] like Figures 1-2 As shown, an air conditioning energy-saving control method includes the following steps:

[0054] Step S1: Obtain the user's expected power consumption and power consumption duration, and obtain the power consumption for each hour based on the expected power consumption and power consumption duration, and mark it as the first power.

[0055] Step S2: After the indoor temperature reaches the specified temperature, the first operating parameters of the outdoor unit and the second operating parameters of the indoor unit are obtained every hour. The current power of the air conditioner is calculated based on the first and second operating parameters and marked as the second power.

[0056] Step S3: Determine whether the first power is greater than the second power. If it is greater, maintain the current power of the air conditioner. If it is less, obtain the current time, confirm the adjustment period according to the current time, and obtain the outdoor temperature change during the adjustment period according to the pre-configured first information mapping table. The first information mapping table is a mapping table of the relationship between time period and temperature change.

[0057] Step S4: Adjust the power of the outdoor unit or indoor unit of the air conditioner according to the change in outdoor temperature.

[0058] To better enable user-defined parameters for adjusting the air conditioner frequency, this invention includes a parameter input mechanism. The input parameters are the user's desired electricity consumption and the duration of use. For example, the user might desire to run the air conditioner for 8 hours at night with 4 kWh of electricity and a temperature of 26°C. In this case, the first power output can be obtained by dividing the desired electricity consumption by the duration of use.

[0059] Since most existing air conditioners are inverter air conditioners, capable of adjusting their frequency according to the environment, it's impossible to determine whether a constant power output is sufficient to meet user needs. Therefore, this invention uses each hour as a detection unit, acquiring the operating parameters of the indoor and outdoor units every hour. Based on a first and a second set of operating parameters, the current power output of the air conditioner is predicted to obtain a second power. When the second power is less than the first power, it indicates that the energy consumption of the air conditioner in that hour is less than the expected value, and the air conditioner can continue operating at its current power. Conversely, when the first power is less than the second power, it indicates that the current power output of the air conditioner is too high, and the power needs to be reduced to meet the user's electricity demand. However, the basic logic requires maintaining the indoor temperature at a specified level, so forcibly reducing the frequency to meet the user's electricity needs is not feasible. Therefore, in this invention, the current time is also taken, and the adjustment period is determined based on the current time. Once the period is known, the outdoor temperature change can be obtained according to the first information mapping table. For example, if the current time is 2:30, falling within the 2:00-3:00 time period, the temperature change during the 2:00-3:00 time period is found according to the first information mapping table. For example, the temperature change is from 28℃ to 26℃. Specifically, the first information mapping table can be obtained from external meteorological data.

[0060] Since the external temperature is close to the designated temperature, the power of the indoor unit of the air conditioner can be reduced to drive the air conditioner in swing mode to ensure user comfort. At the same time, the second power level is also reduced to approach the first power level, achieving the effect of adjusting the air conditioner frequency according to the user-set parameters, thus bringing the air conditioner's energy consumption closer to the user's expected electricity consumption.

[0061] It's worth noting that, since the energy consumption of the air conditioner is relatively difficult to calculate using the first and second operating parameters in the initial stage of operation, the energy consumption at which the temperature eventually stabilizes can be used as the energy consumption during the initial operation.

[0062] Preferably, the steps in step S2 for obtaining the first operating parameters of the outdoor unit and the second operating parameters of the indoor unit are as follows:

[0063] The steps to obtain the first runtime parameter are as follows:

[0064] Get the current fan speed in the outdoor unit of the air conditioner, get the fan energy consumption according to the pre-configured second information mapping table, and use the fan energy consumption as the first operating parameter, wherein the second information mapping table is a mapping table of the relationship between fan speed and energy consumption;

[0065] Since the fan power in the outdoor unit of an air conditioner is relatively stable, its energy consumption is relatively fixed at a fixed speed. Therefore, a second information mapping table can be constructed in advance based on the fan parameters provided by the manufacturer. By detecting the fan speed, the energy consumption of this fan can be found through the second information mapping table, thus obtaining the first operating parameter. It is worth noting that when there are multiple fans in the outdoor unit of the air conditioner, the energy consumption of multiple fans needs to be obtained and then added together to obtain the first operating parameter.

[0066] The steps to obtain the second running parameter are as follows:

[0067] The specified temperature and indoor space volume are input into the simulation model to obtain the compressor's energy consumption. The compressor's energy consumption is used as the second operating parameter. The simulation model is a model of the air conditioning system established using thermodynamic and electrical principles.

[0068] Thermodynamics reveals the amount of heat energy required to maintain a fixed temperature in a space of fixed size. Electrical principles then determine the energy consumption of the compressor at a given power level to regulate this heat energy. Therefore, a simulation model can be constructed using existing thermodynamic and electrical principles. Users need to input their desired electricity consumption and usage duration, as well as the room size (indoor space volume). By specifying the temperature and indoor space volume, the energy consumption of the compressor is immediately obtained from the simulation model.

[0069] Preferably, before calculating the second power, the following steps also need to be performed:

[0070] The first temperature inside the outdoor unit of the air conditioner is obtained, and it is determined whether the first temperature is higher than the first temperature threshold. If it is higher, the first operating parameter is corrected using the trained neural network.

[0071] The formula for correcting the first operating parameter is as follows:

[0072] ;

[0073] ;

[0074] ;

[0075] in For the corrected first operating parameters, The weights of the j-th hidden layer, c is the output of the neuron in the j-th hidden layer, and c is the bias of the output layer. For activation function, Let be the weight of the first temperature in the j-th hidden layer. Let the weight be the weight of the first running parameter in the j-th hidden layer. It is the input of the input layer. For the first temperature, For the first running parameter, It is the bias of neurons in the hidden layer.

[0076] Since the outdoor unit of an air conditioner is a heat dissipation component, and the second information mapping table is based on fan parameters provided by the manufacturer, its operating ambient temperature is lower than the ambient temperature of the outdoor unit. High temperatures increase the resistance of the fan's internal conductors, thus increasing the fan's energy consumption. This causes the first operating parameter to fail to accurately reflect the actual energy consumption of the fan. Therefore, this invention acquires the first temperature inside the outdoor unit and determines whether it exceeds a first temperature threshold, which can be the temperature at which the manufacturer tested the fan parameters. If the first temperature exceeds the first temperature threshold, it indicates that the current ambient temperature affects the acquisition of fan energy consumption, requiring correction. This invention incorporates a neural network; after acquiring the first temperature, the neural network corrects the first operating parameter to ensure it matches the actual parameter values, thereby enabling more accurate calculation of the second power.

[0077] Preferably, the formula for calculating the second power in step S2 is as follows:

[0078] ;

[0079] in , and These are the proportionality coefficients, For the first running parameter, C represents the second operating parameter, and C represents other conventional energy consumption.

[0080] The energy consumption of an air conditioner mainly consists of the fixed energy consumption of the compressor, outdoor unit fan, and some other equipment. Therefore, the real-time second power can be predicted by allocating the corresponding proportions, and the air conditioner frequency can be adjusted according to the second power, so as to adjust the air conditioner according to the parameters set by the user.

[0081] Preferably, the specific steps of step S4 are as follows:

[0082] The difference between the outdoor temperature and the specified temperature is obtained as the first temperature difference. It is then determined whether the first temperature difference is less than the second temperature threshold. If it is not less than the second temperature threshold, the current power of the air conditioner is maintained. If it is less than the second temperature threshold, the required refrigerant flow rate of the indoor unit of the air conditioner is obtained through the first temperature difference.

[0083] The motor speed of the compressor is adjusted according to the flow rate of the refrigerant;

[0084] The fan of the outdoor unit of the air conditioner is adjusted based on the motor speed of the compressor after adjustment.

[0085] In step S4, the present invention obtains the outdoor temperature as the direction for adjusting the air conditioner. When the outdoor temperature differs significantly from the indoor temperature, it is necessary to maintain the current power of the air conditioner to ensure the user has a better experience. When the first temperature difference is less than the second temperature threshold, the difference between the outdoor and indoor temperatures is small. At this time, the refrigerant flow can be adjusted based on the first temperature difference, thereby achieving frequency conversion of the compressor motor. Since the required heat dissipation of the outdoor unit also changes after the amount of refrigerant required changes, the present invention will also readjust the fan speed of the outdoor unit according to the compressor motor speed, ultimately achieving an energy-saving effect.

[0086] Preferably, the formula for obtaining the refrigerant flow rate is as follows:

[0087] ;

[0088] in , , These are the gains of the first PID controller. This is the first temperature difference value. This is the cumulative effect of all temperature differences that have existed throughout history after temperature adjustments. This refers to the temperature difference that existed after the last temperature adjustment;

[0089] The specific formula for adjusting the motor speed of the compressor is as follows:

[0090] C ;

[0091] in For refrigerant flow rate, , , These are the gains of the second PID controller. To adjust the time, Historically, the temperature has not reached the optimal temperature. The cumulative error value of the compressor motor speed at the second temperature threshold;

[0092] The specific steps for adjusting the fan of the outdoor unit of the air conditioner based on the adjusted motor speed of the compressor are as follows:

[0093] Based on the pre-configured third information mapping table, the fan speed of the outdoor unit of the air conditioner is obtained. The third information mapping table is a mapping table of the heat dissipation demand relationship of the compressor under different refrigerant flow rates.

[0094] An air conditioning energy-saving control system, using the aforementioned air conditioning energy-saving control method, includes an acquisition module, a calculation module, a judgment module, and an adjustment module;

[0095] The acquisition module is used to acquire the user's expected power consumption and power consumption duration, and to acquire the power consumption for each hour based on the expected power consumption and power consumption duration, which is marked as the first power.

[0097] The judgment module is used to determine whether the first power is greater than the second power. If it is greater, the current power of the air conditioner is maintained. If it is less, the current time is obtained, the adjustment period is determined according to the current time, and the outdoor temperature change during the adjustment period is obtained according to the pre-configured first information mapping table. The first information mapping table is a mapping table of the relationship between the time period and the temperature change.

[0098] The adjustment module is used to adjust the power of the outdoor unit or indoor unit of the air conditioner according to the change in outdoor temperature.

[0099] Preferably, the calculation module includes a first calculation submodule and a second calculation submodule;

[0100] The first calculation submodule obtains the current fan speed in the outdoor unit of the air conditioner, obtains the fan energy consumption according to the pre-configured second information mapping table, and uses the fan energy consumption as the first operating parameter, wherein the second information mapping table is a mapping table of the relationship between fan speed and energy consumption;
