[0013] The present application also proposes a power consumption calculation device for air-conditioning equipment, wherein the air-conditioning equipment includes a controller, a first type of load, a second type of load and a third type of load, wherein the first type of load includes a load driven by the controller, the second type of load includes a load related to power and voltage, and the third type of load includes a load with fixed power during operation, and the device includes: a first determination module, used to determine a first power consumption of the first type of load based on the output power of the first type of load; a second determination module, used to determine a second power consumption of the second type of load based on the rated voltage, rated power and current voltage of the second type of load; a third determination module, used to determine a third power consumption of the third type of load based on the rated power and accumulated opening time of the third type of load; and a fourth determination module, used to determine the power consumption of the air-conditioning equipment based on the first power consumption, the second power consumption and the third power consumption.

Therefore, the accuracy of the first power consumption determined based on the output power of the first type of load can be guaranteed; then, based on the rated voltage, rated power and current voltage of the second type of load, the second power consumption of the second type of load is determined. The power of the second type of load is related to the voltage. Therefore, the power consumption is determined based on its rated voltage and current voltage with high accuracy; then, based on the rated power and cumulative start-up time of the third type of load, the third power consumption of the third type of load is determined. The power of the third type of load is fixed during operation, and the third power consumption can be determined based on its cumulative start-up time, which is simple to calculate; finally, the power consumption of the air-conditioning equipment is determined based on the first power consumption, the second power consumption and the third power consumption.

[0017] In other words, by dividing the loads that consume power when the air-conditioning equipment is running into different categories (i.e., first-category loads, second-category loads, and third-category loads), and then calculating the power consumption corresponding to each type of load respectively, and finally adding up the power consumption, the power consumption of the air conditioner can be determined. The calculation is simple, the result is accurate, and there is no need to set up an additional hardware for detecting power, which can save the production cost of the air-conditioning equipment.

DETAILED DESCRIPTION

[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0021] To facilitate understanding of this application, the terms and background technologies that appear in this application are explained below: 1. Cloud server: is an Internet Technology (IT) product that provides cloud computing services. The characteristics of cloud servers are simplicity, efficiency, security, reliability, elastic scalability, and reduced difficulty in development and operation and overall IT costs. It provides a comprehensive business service platform for various Internet users, integrates the three core elements of Internet applications: computing, storage, and network, and provides public Internet infrastructure services. The service construction method of this application can be implemented based on cloud servers.

[0022] 2. Cloud technology refers to a hosting technology that unifies hardware, software, network and other resources in a wide area network or local area network to achieve data computing, storage, processing and sharing. Cloud technology is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on the cloud computing business model. It can form a resource pool and be used on demand, which is flexible and convenient. Cloud computing technology will become an important support. The background services of technical network systems require a large amount of computing and storage resources, such as video websites, picture websites and more portal websites. With the high development and application of the Internet industry, each item may have its own identification mark in the future, and all need to be transmitted to the background system for logical processing. Data of different levels will be processed separately. All kinds of industry data need strong system backing support, which can only be achieved through cloud computing.

[0023] Cloud computing is a computing model that distributes computing tasks on a resource pool composed of a large number of computers, so that various application systems can obtain computing power, storage space and information services as needed. The network that provides resources is called a "cloud". The resources in the "cloud" are infinitely expandable in the eyes of users, and can be obtained at any time, used on demand, expanded at any time, and paid for by use. Among them, the power consumption calculation method of the present application can be implemented on a power consumption calculation cloud platform, and the power consumption calculation cloud platform can be implemented based on cloud servers and cloud technologies.

[0024] In the related art, when calculating the power consumption of air-conditioning equipment, it is usually necessary to separately detect and measure the power consumption of the air-conditioning equipment by setting a power metering sensor or a current and voltage sensor. The power metering sensor and the current and voltage sensor are usually connected to the power line of the air-conditioning to transmit the electrical parameters such as the current and voltage of the air-conditioning to the central control system or monitoring platform for relevant calculations to obtain the power consumption of the air-conditioning.

[0025] Although the power metering sensor or current and voltage sensor can monitor the power usage of the air conditioner, the separately installed power metering sensor or current and voltage sensor increases the production cost of the air conditioner. During the use of the air conditioner, the installation, maintenance and calibration of the power metering sensor or current and voltage sensor will also incur additional expenses.

[0026] In order to solve the above technical problems, an embodiment of the present application provides a method for calculating power consumption.

[0027] The following is an introduction to the application scenarios of the technical solution of this application. The power consumption calculation method provided by this application can be applied to Figure 1 In the illustrated air conditioning system 1000 , the air conditioning system 1000 includes an air conditioning device 100 , and the air conditioning device 100 includes a first type of load 10 , a second type of load 20 , and a third type of load 30 .

[0028] The air conditioning device 100 is any device capable of adjusting temperature, humidity, air quality, etc., such as a convection terminal, a radiation terminal, a convection and radiation coupling terminal, etc.

[0029] In one embodiment, the air conditioning device 100 includes a processor 40 and a memory 50. The memory 50 can be used to store the power consumption of various loads and the historical power consumption of the air conditioning device 100, etc.

[0030] In one embodiment, the air conditioning system 1000 further includes a server 200 , and the server 200 and the air conditioning device 100 communicate via a network.

[0031] Optionally, the server 200 may be an independent physical server 200, or a server 200 cluster or distributed system composed of multiple physical servers 200, or a cloud server 200 that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The embodiments of the present application are not limited to this.

[0032] In one embodiment, the air conditioning system 1000 further includes a terminal 400, which includes a display. The terminal 400 can communicate with the air conditioning device 100 to determine the power consumption of the air conditioning device 100, and the display of the terminal 400 can also display the power consumption of the air conditioning device 100.

[0033] In one embodiment, the terminal 400 may be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, portable wearable devices, and the like.

[0034] In one embodiment, the air conditioning device 100, the server 200 and the terminal 400 all communicate through a network. For example, any two of the air conditioning device 100, the server 200 and the terminal 400 can communicate wirelessly (such as wireless LAN (Wireless Fidelity, wifi) communication, Bluetooth communication, infrared communication, etc.).

[0035] It can be understood that the communication between the air conditioning device 100, the server 200 and the terminal 400 is not limited to the above communication method and is not restricted to this.

[0036] For example, when communicating via wifi, the air-conditioning device 100 and the terminal 400 communicate with the server 200 respectively, and then the server 200 realizes the communication between the air-conditioning device 100 and the server 200 (or the terminal 400); for example, when communicating via Bluetooth or infrared, the air-conditioning device 100 and the terminal 400 are each provided with a corresponding communication module to directly realize the communication between the two.

[0037] In one embodiment, the power consumption calculation method can be implemented by the air-conditioning device 100 in an offline state; or by the air-conditioning device 100 and the terminal 400; it can also be implemented by the air-conditioning device 100 in an online state; or by the air-conditioning device 100 and the terminal 400; or by the server 200 and the terminal 400; or by the air-conditioning device 100, the server 200 and the terminal 400, and so on.

[0038] The following is a detailed description of the power consumption calculation method of this application: See also Figure 1 and Figure 2An embodiment of the present application provides a method for calculating power consumption. The power consumption calculation method is applied to an air-conditioning device, and the controller of the air-conditioning device executes the method as an example for explanation. The air-conditioning device includes a controller, a first type of load, a second type of load, and a third type of load. The first type of load includes a load driven by the controller, the second type of load includes a load related to power and voltage, and the third type of load includes a load with fixed power during operation.

[0039] The controller may be a microcontroller unit (MCU) (a microcomputer chip integrating multiple functions such as a central processing unit (CPU), memory, and input / output (I / O) interface), a digital signal processor (DSP) (a controller for digital signal processing), etc.

[0040] Among them, the first type of load includes electrical components, equipment, or systems driven by the controller through electrical circuits, etc. The controller can control the working conditions or working parameters of the first type of load according to the set parameters such as target temperature, target humidity and target air quality to drive each first type of load to perform corresponding work, thereby realizing various functions of the air-conditioning equipment. The first type of load affects the working performance and operating efficiency of the air conditioner.

[0041] For example, the first type of load may be a compressor (a refrigeration (and / or heating) device in an air-conditioning device, used to compress the refrigerant and push the refrigerant to circulate in the refrigeration or heating system of the air-conditioning device), a fan motor (a device used to circulate cold air or hot air into the air through an evaporator or condenser to ensure heat exchange in the air-conditioning system), etc. For example, taking a compressor as an example, the controller can achieve the temperature control function of the air-conditioning by adjusting the working conditions of the compressor (such as start and stop, frequency adjustment, etc.).

[0042] Optionally, the controller is used to collect the output voltage and the output current of the first type of load, and the output power of the first type of load is determined based on the output voltage and the output current.

[0043] Among them, the controller can monitor the voltage of the first type of load through a voltage sensor (such as a voltage divider, etc.), and measure the current output by the first type of load through a current transformer (or a Hall effect sensor, etc.). The controller determines the output voltage and output current of the first type of load by obtaining the voltage signal and the current signal, and determines the output power of the first type of load by, for example, calculating the product of the output voltage and the output current.

[0044] It should be pointed out that when calculating the power consumption of the first type of load, what needs to be paid attention to is the actual amount of work completed by the first type of load, that is, the mechanical work provided by the first type of load. Therefore, the controller obtains the output current and output voltage of the first type of load at this time to calculate the output power of the first type of load.

[0045] For example, taking the compressor as the first type of load, the output power of the compressor can represent the actual mechanical work completed by the compressor during operation (such as the energy required to compress the refrigerant, etc.), and the power consumption is related to the output power of the compressor (usually the product of the output power of the compressor and time). Therefore, the controller collects the output current and output voltage of the compressor at any second (s) at the current moment, and determines the output power of the compressor in the current second by calculating the product of the output current and the output voltage. Then, the power consumption of the compressor in the current second can be determined by calculating the product of the compressor and time (1s).

[0046] Among them, the second type of load includes loads related to power and voltage, which can be inductive components whose power is directly affected by the input voltage when turned on and running, and whose working principle is based on electromagnetic induction. For example, resistance wire, crankcase heating belt, etc. The inductive component can generate a corresponding magnetic field based on the input voltage to affect the magnitude of the current in the inductive component, thereby determining the power consumption of the inductive component, and further affecting the power consumption of the second type of load.

[0047] The third type of load includes loads with fixed power during operation. The third type of load may be a load driven by a stable voltage provided by the air conditioner during operation. The power of such loads is usually not relatively fixed after being turned on and will not change significantly. For example, the third type of load may be a main control board, solenoid valve, electronic expansion valve, etc. of the air conditioner.

[0048] Please refer to the figure, the power consumption calculation method of this application includes: Step 011: Determine a first power consumption of the first type of load based on the output power of the first type of load.

[0049] The first power consumption may be the total power consumption of the first type of load during one start and stop process of the air-conditioning device; or, the first power consumption may be the accumulated power consumption of the first type of load during the entire life cycle of the air-conditioning device.

[0050] Optionally, the first power consumption K1 of any first-category load is determined based on the following formula:

[0051] Among them, t1 is the first preset duration, which can be 0.1s, 0.4s, 0.5s, 0.8s, 0.9s, 1s, 1.1s, 1.2s, 1.5s, etc. It can be considered that within the first preset duration, the output power of the first type of load is constant. Therefore, the power consumption calculated based on the output power can represent the total power consumption of the first type of load within the first preset duration.

[0052] Among them, nk1 is the operation time of the first type of load (it can be the total operation time of the first type of load within the operation time of one start and stop of the air conditioner). For example, after the air conditioner is powered on, the controller can capture the start signal of the first type of load when it starts to run and the stop signal when the first type of load stops working, and calculate the time difference between the two signals based on the timestamps of the two signals, so as to determine that the total operation time of the first type of load is nk1.

[0053] Wherein, a is a power correction coefficient, and each first-category load has a corresponding power correction coefficient. By calculating the power correction coefficient, the accuracy of the power consumption calculation of the first-category load can be provided.

[0054] Wherein, the value range of a is (0, 1]. For example, in the experimental operation stage of the air-conditioning equipment, a power metering sensor can be set for the first type of load to obtain the power consumption K11 of the first type of load within the preset time nk1; then a=1, and the power consumption K12 of the first type of load is calculated based on the above formula; then the difference between K11 and K12 is calculated. When the difference is less than (or equal to) the preset difference, it can be considered that the calculation accuracy at this time meets the calculation accuracy requirements for power consumption, K12 can be used as the first power consumption K1 of the first type of load, and its accuracy can be guaranteed; when the difference is greater than (or equal to) the preset difference, it can be considered that the calculation accuracy at this time does not meet the calculation accuracy requirements for power consumption, the accuracy of K1 is not enough to meet user needs, and deviations may occur in the power consumption calculation.

[0055] Therefore, the power correction factor needs to be further determined to improve the accuracy of power consumption calculation.

[0056] For example, taking the first type of load as a compressor (or fan motor) as an example, due to the hardware and physical characteristics of the compressor, the power factor of the compressor (or fan motor) is usually unable to be obtained, resulting in the calculated output power of the compressor (or fan motor) having low accuracy. The present application can correct the output power by a power correction coefficient to ensure the accuracy of the calculated first power consumption. Since the power factor of a compressor (or fan motor) is usually approximately linearly related to its output power or its operating frequency calculated at the current moment, the power correction coefficient a can be determined based on the output power calculated at the current moment of the compressor (or fan motor):

[0057] Among them, pt is the output power of the compressor (or fan motor) calculated at the current moment, m1 and n1 are fitting correction coefficients, which can be obtained through experiments (actual measurements) or table lookup.

[0058] The power correction factor a can also be determined based on the current operating frequency of the compressor (or fan motor):

[0059] Among them, f is the current operating frequency of the compressor (or fan motor), m2 and n2 are fitting correction coefficients, which can be obtained through experiments (actual measurements) or table lookup.

[0060] According to the re-determined power correction coefficient a, K12 calculated when the power correction coefficient a takes a value of 1 is recalculated to obtain K13. After multiple experimental calibrations, the first power consumption K1 (K13) of the first type of load calculated based on the re-determined power correction coefficient a in this application has an accuracy within 3% of the actual power consumption K11.

[0061] It can be understood that, generally speaking, the higher the output power pt at the current moment, the larger a is and the closer it is to 1; the larger the operating frequency f at the current moment, the larger a is and the closer it is to 1. Since the voltage at which the air-conditioning equipment operates may also have an impact on the calculation of the power factor, after determining a, in the experimental stage, by setting current and voltage sensors, etc., to obtain the actual power consumption of the first type of load, a can be verified and corrected again based on the comparison between the actual power consumption and the power consumption of the first type of load calculated based on the calculated a, so as to further ensure the accuracy of the first power consumption K1 of the first type of load calculated based on the method of the present application.

[0062] It should be noted that each first-class load has a corresponding power correction coefficient a. For example, an air-conditioning device includes two compressors (power correction coefficients are a1 and a2, output powers are P11 and P12, and operation durations are both nk1), and t1=1s. The first power consumption K14 of the air-conditioning device is:

[0063] Specifically, the first type of load includes a load driven by a controller of an air-conditioning device, and the first power consumption of the first type of load includes the actual mechanical work done by the load. By obtaining the output voltage and output current of the first type of load at the current moment, the output power of the first type of load is calculated according to the product of the output voltage and the output current, and then the power consumption of the first type of load within 1 second is determined by calculating the product of the output power and the first preset time (1 second). In the case where the first type of load runs for a duration of nk1, the power consumption of the first type of load in each second within the duration of nk1 is calculated separately to obtain the power consumption of the first type of load for nk1 1 seconds; and then the power consumption within each 1 second is accumulated to determine the first power consumption of the first type of load in the duration of nk1. Since the first preset time is short enough, the accuracy of the output power calculated by the controller based on the output voltage and the output current can be guaranteed, so that the accuracy of the first power consumption can also be guaranteed.

[0064] Step 012: Determine a second power consumption of the second type of load based on the rated voltage, rated power and current voltage of the second type of load.

[0065] Among them, the rated voltage of the second type of load can be determined by experiments or table lookup.

[0066] The current voltage includes the input voltage of the second type of load at the current moment.

[0067] The second power consumption may be the total power consumption of the second type of load during one start and stop process of the air-conditioning device; or, the second power consumption may be the accumulated power consumption of the second type of load during the entire life cycle of the air-conditioning device.

[0068] Optionally, the second power consumption K2 of any second type load is determined based on the following formula:

[0069] Among them, nk2 is the operation time of the second type of load. Similarly, after the air conditioner is powered on, the controller can capture the start signal of the second type of load starting to run and the stop signal of the second type of load when it stops working, and calculate the time difference between the two signals based on the timestamps of the two signals, so as to determine that the total working time of the second type of load is nk2.

[0070] Wherein, U is the current voltage of the second type of load, which may be the input voltage input into the second type of load at the current moment collected by the controller.

[0071] Among them, Ue is the rated voltage of the second type of load; Pe is the rated power of the second type of load. Both can be determined by experiments or table lookup, and are rated parameters.

[0072] Among them, t2 is the second preset time length, which can be 0.1s, 0.4s, 0.5s, 0.8s, 0.9s, 1s, 1.1s, 1.2s, 1.5s, etc. It can be considered that within the second preset time length, the output power of the second type of load is constant. Therefore, the power consumption calculated based on the current voltage can represent the total power consumption of the second type of load within the preset time length. The first preset time length and the second preset time length may be the same or different.

[0073] For example, an air-conditioning device includes two compressor crankshaft heating belts, and the rated power of the two compressor crankshaft heating belts is 40 watts (W) and the rated voltage is 220 volts (V). Assuming that the current voltage of the two compressor crankshaft heating belts is 220V, then, in this second (t2=1s), the second power consumption K21 of the air-conditioning device is:

[0074] Specifically, the second type of load includes loads related to power and voltage. By obtaining the current voltage (i.e., input voltage) of the second type of load at the current moment to determine its current power at the current moment, and then calculating the product of the current power and the preset duration (1 second), the power consumption of the second type of load within 1 second can be determined. In the case where the second type of load runs for a duration of nk2, the power consumption of the second type of load in each second within the duration of nk2 is calculated separately to obtain the power consumption of the second type of load for nk2 one seconds; and then the power consumption within each 1 second is accumulated to determine the second power consumption of the second type of load within the duration of nk2. Similarly, since the second preset duration is short enough, the second power consumption calculated based on the current voltage of the second type of load has a higher accuracy.

[0075] Step 013: Determine the third power consumption of the third type of load based on the rated power and the accumulated start-up time of the third type of load.

[0076] Among them, the rated power of the third type of load can be determined by experiments or table lookup.

[0077] The accumulated start-up time may be the actual operation time of the third type of load.

[0078] The third power consumption may be the total power consumption of the third type of load during one start and stop process of the air-conditioning equipment; or, the third power consumption may be the accumulated power consumption of the third type of load during the entire life cycle of the air-conditioning equipment.

[0079] Optionally, the third power consumption K3 of any third type of load is determined based on the following formula:

[0080] Among them, nk3 is the power-on time of the air conditioner. Similarly, after the air conditioner is powered on, the controller can capture the power-on signal and the power-off signal of the air conditioner, and calculate the time difference between the two signals based on the timestamps of the two signals, thereby determining that the power-on time of the air conditioner is nk3.

[0081] Wherein, Pw is the rated power of the third type of load, which can be determined by experiments or table lookup.

[0082] Wherein, O is the current switch state of the third type of load. When the switch state of the third type of load at the current moment is in the on state, O=1; when it is in the off state, O=0.

[0083] Among them, t3 is the third preset time length, which can be 0.1s, 0.4s, 0.5s, 0.8s, 0.9s, 1s, 1.1s, 1.2s, 1.5s, etc. It can be considered that within the third preset time length, the switching state of the third type of load is constant. Therefore, the power consumption calculated at this time can represent the total power consumption of the third type of load within the preset time length. The third preset time length and the first preset time length and the second preset time length may be the same or different.

[0084] For example, the third type of load includes a main control board and two solenoid valves, the rated power of the main control board is 10W, and the rated power of the two solenoid valves is 5W. Assuming that the main control board and the two solenoid valves are both in the open state (O=1) at the current moment, the third power consumption K31 of the air conditioning equipment in this second (t2=1s) is:

[0085] Specifically, the power of the third type of load is usually rated power when working, and the third power consumption at the current moment can be determined according to the switch state of the third type of load. When the switch state of the third type of load is on, the power consumption of the third type of load within 1 second can be determined according to the rated power of the third type of load and the third preset time (1s). When the switch state of the third type of load is off, the third type of load does not consume power, and O=0 is taken at this time, that is, the power consumption of the third type of load within this 1 second is 0. When the power-on time of the air-conditioning equipment is nk3, the switch state of the third type of load every 1 second within the nk3 time is distinguished to determine the power consumption of the third type of load every 1 second; and then the power consumption of the third type of load within each 1 second is accumulated to determine the third power consumption of the third type of load within the nk3 time. Calculating the power consumption based on the switch state of the third type of load can ensure the accuracy of the third power consumption.

[0086] It can be understood that nk3 may also be the operating time of the third type of load. In the case where nk3 is the operating time of the third type of load, the third power consumption K3 may be determined based on the following formula:

[0087] Among them, Pw is the rated power of the third type of load; t3 is the third preset time length.

[0088] The operating signal of the third type of load can be collected by the controller, and the operating duration nk3 of the third type of load can be determined according to the timestamp of the operating signal. The power consumption of the third type of load within nk3 1 seconds can be accumulated to determine the third power consumption of the third type of load.

[0089] Step 014: Determine the power consumption of the air conditioning equipment based on the first power consumption, the second power consumption and the third power consumption.

[0090] Optionally, the power consumption Z of the air conditioning equipment is determined based on the following formula:

[0091] Among them, K1 is the first power consumption, K2 is the second power consumption, and K3 is the third power consumption.

[0092] Specifically, when the first power consumption K1, the second power consumption K2 and the third power consumption K3 are determined, the first power consumption K1, the second power consumption K2 and the third power consumption K3 are added together to determine the total power consumption Z of the air-conditioning device.

[0093] In this way, the air conditioning equipment includes a controller, a first type of load, a second type of load and a third type of load. The first type of load includes a load driven by the controller, the second type of load includes a load related to power and voltage, and the third type of load includes a load with fixed power during operation. First, based on the output power of the first type of load, the first power consumption of the first type of load is determined. Since the first type of load is driven by the controller, the first power consumption includes the actual mechanical work done by the first type of load, so the accuracy of the first power consumption determined based on the output power of the first type of load can be guaranteed; then, based on the rated voltage, rated power and current voltage of the second type of load, the second power consumption of the second type of load is determined. The power of the second type of load is related to voltage. Therefore, the power consumption is determined based on its rated voltage and current voltage, and the accuracy is higher; then, based on the rated power and cumulative opening time of the third type of load, the third power consumption of the third type of load is determined. The power of the third type of load is fixed during operation, and the third power consumption can be determined according to its cumulative opening time, which is simple to calculate; finally, based on the first power consumption, the second power consumption and the third power consumption, the power consumption of the air conditioning equipment is determined.

[0094] In other words, by dividing the loads that consume power when the air-conditioning equipment is running into different categories (i.e., first-category loads, second-category loads, and third-category loads) according to their power characteristics, and then calculating the power consumption corresponding to each type of load according to the characteristics of each type of load, and finally adding up the power consumption, the power consumption of the air conditioner can be determined. The calculation result is accurate, and there is no need to set up an additional hardware for detecting power, which can save the production cost of the air-conditioning equipment.

[0095] In some embodiments, the power consumption Z of the air conditioning equipment is determined based on the following formula:

[0096] Among them, K1 is the first power consumption, K2 is the second power consumption, and K3 is the third power consumption.

[0097] Among them, Z0 is the historical power consumption of the air-conditioning equipment.

[0098] Specifically, for example, the controller can store the accumulated power consumption of the air-conditioning device into the memory of the air-conditioning device at preset intervals (such as 1 minute (min), 5 minutes, 10 minutes, etc.) to update the power consumption Z of the air-conditioning device. When the air-conditioning device is powered on again after power failure, the controller can read the data of the last updated accumulated power consumption Z0, and based on the data, after calculating the power consumption at the current moment, update the accumulated power consumption Z again. In this way, Z represents the power consumption of the air-conditioning device throughout its life cycle, that is, the user can clearly know the total power consumption of the air-conditioning device throughout its life cycle.
