[0072] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0073] The main solution in this application embodiment is:

[0074] In this embodiment, for ease of description, the following description will focus on the air conditioner capacity display device as the implementing entity.

[0075] With the development of modern technology and people's increasing demands for quality of life, air conditioners, as important household appliances, have been widely used in home and commercial environments. Air conditioner capacity is a crucial operating parameter. By acquiring and displaying this capacity, users can receive intuitive and accurate information about the air conditioner's operating status, thus helping them to better adjust the air conditioner to achieve a comfortable ambient temperature.

[0076] Existing air conditioners typically require a large number of sensors to acquire numerous parameters for capacity display, and then perform calculations based on these parameters using complex formulas, making the display process cumbersome and costly.

[0077] This application provides a method for displaying the capacity of an air conditioner, wherein the air conditioner includes an evaporator and a compressor, and the method includes:

[0078] Obtain indoor temperature, evaporator temperature, air volume of the air conditioner, and operating parameters of the compressor;

[0079] The cooling or heating capacity of the air conditioner under the current operating conditions is calculated based on the indoor temperature, evaporator temperature, air volume of the air conditioner, and compressor operating parameters.

[0080] When an air conditioner capacity display control command is received, the cooling or heating capacity of the air conditioner is displayed.

[0081] In this embodiment, the cooling or heating capacity of the air conditioner can be calculated simply by obtaining the indoor temperature, evaporator temperature, air volume of the air conditioner, and compressor operating parameters. This reduces the number of parameters that need to be measured and the complexity of the calculation, improves the calculation efficiency, and thus enhances the convenience of displaying the air conditioner's capacity.

[0082] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or air conditioner capacity display device capable of performing the above functions. The following description uses an air conditioner capacity display device as an example to illustrate this embodiment and the subsequent embodiments.

[0083] Based on this, embodiments of this application provide a method for displaying the capacity of an air conditioner, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the air conditioner capability display method of this application.

[0084] In this embodiment, the air conditioner includes an evaporator and a compressor.

[0085] As is understandable, the evaporator is the heat exchange component of an air conditioner, capable of absorbing heat from the room in cooling mode. When the refrigerant flows through the evaporator, it changes from a liquid to a gaseous state, thereby absorbing a large amount of heat and lowering the indoor air temperature. Conversely, in heating mode, the evaporator releases heat to the external environment. The compressor is responsible for compressing the refrigerant gas, increasing its pressure and thus its temperature. In cooling mode, the compressor compresses the low-temperature, low-pressure gas from the evaporator into a high-temperature, high-pressure gas, which is then sent to the condenser. In heating mode, the compressor also compresses the refrigerant gas, but the refrigerant circulation direction is reversed compared to cooling mode. The compressed, high-temperature, high-pressure gas directly enters the indoor heat exchanger (which now acts as the evaporator) to heat the indoor air.

[0086] The air conditioner capacity display device includes steps S100 to S300:

[0087] Step S100: Obtain indoor temperature, evaporator temperature, air volume of the air conditioner, and operating parameters of the compressor.

[0088] It's important to clarify that indoor temperature refers to the actual ambient temperature within the space where the air conditioner is located. Understandably, indoor temperature affects the air conditioner's heat load. For example, if the indoor temperature is high, the heat load from the external environment is greater, requiring the air conditioner to generate more cooling capacity to maintain the indoor temperature. Conversely, when the indoor temperature is low, the heat load from the external environment is smaller, and the required cooling capacity of the air conditioner will decrease accordingly. Therefore, indoor temperature can be used as one of the parameters for calculating the air conditioner's operating capacity. Specifically, indoor temperature can be obtained in real-time through the air conditioner's built-in temperature sensor or through data exchange with other smart devices in the room, such as a smart temperature control system.

[0089] The evaporator temperature reflects the evaporator's state during operation. In cooling mode, the refrigerant in the evaporator absorbs heat from the room. Too low an evaporator temperature can lead to frost or even ice formation, affecting heat exchange efficiency; too high a temperature may prevent effective heat absorption. In heating mode, the evaporator also plays a crucial role in heat exchange, and its temperature changes affect heat exchange efficiency. Therefore, evaporator temperature can also be used as one of the parameters for evaluating the air conditioner's capabilities. In this embodiment, the evaporator temperature can be monitored in real time using a temperature sensor installed on the evaporator, ensuring the accuracy and timeliness of the data.

[0090] Airflow rate refers to the volume of air blown out by the air conditioner. A larger airflow rate helps circulate indoor air more quickly, thereby improving heat exchange efficiency. In cooling mode, a larger airflow rate helps lower the indoor temperature more quickly; while in heating mode, it helps raise the indoor temperature rapidly. Therefore, airflow rate can also be used as one of the parameters for calculating the air conditioner's capacity. In this embodiment, the airflow rate can be monitored by a built-in wind speed sensor or fan speed sensor to provide real-time feedback on the airflow status of the air conditioner.

[0091] The compressor is responsible for compressing the refrigerant and raising its temperature, thereby achieving refrigerant circulation. The compressor's operating parameters, such as operating frequency and discharge temperature, directly affect the refrigerant compression efficiency. A higher compressor operating frequency means higher compression power, which may result in higher cooling or heating capacity. The compressor discharge temperature reflects the energy conversion during compression; a higher discharge temperature may mean higher compression efficiency. Therefore, the compressor's operating parameters can also be used as one of the parameters for calculating the air conditioner's capacity. In this embodiment, the compressor's operating parameters can be monitored in real time by sensors installed on the compressor. These sensors can capture key data such as the compressor's operating frequency, current, voltage, and discharge temperature. By acquiring indoor temperature, evaporator temperature, airflow from the air conditioner, and the compressor's operating parameters, a comprehensive data foundation is provided for calculating the air conditioner's capacity.

[0092] Step S200: Calculate the cooling or heating capacity of the air conditioner under the current operating conditions based on the indoor temperature, evaporator temperature, air volume of the air conditioner, and compressor operating parameters.

[0093] It's understandable that air conditioners operate in both cooling and heating modes. In cooling mode, the air conditioner primarily absorbs indoor heat through the evaporator and releases it outdoors to lower the indoor temperature. In this mode, calculating the cooling capacity requires considering the interactions between various parameters and their impact on heat exchange efficiency. Specifically, increasing the airflow will promote rapid heat transfer, while compressor operating parameters such as operating frequency and exhaust temperature are directly related to refrigerant compression efficiency and cooling output. Therefore, by inputting these parameters and performing comprehensive calculations using a pre-set algorithm model or formula, the cooling capacity of the air conditioner under the current operating conditions can be determined.

[0094] In heating mode, the air conditioner operates in the opposite manner to cooling mode. It primarily uses the compressor to compress the refrigerant and release heat into the room to raise the indoor temperature. In this mode, the calculation of heating capacity must also consider the effects of the aforementioned parameters. Since the evaporator becomes the heat source during heating, its temperature control becomes particularly important, ensuring sufficient heat release while preventing overheating that could reduce system efficiency. Furthermore, the airflow and compressor operating parameters also directly affect heat exchange efficiency and heating capacity in heating mode. Therefore, through a similar calculation process, the heating capacity of the air conditioner under heating conditions can be determined.

[0095] It is worth noting that, in order to improve the accuracy and efficiency of calculation, the preset algorithm model or preset formula in this embodiment can be trained and optimized by extracting the correlation and weight between various parameters based on a large amount of experimental data and historical data, and by machine learning or optimization algorithms, so as to ensure that the calculated cooling capacity or heating capacity can accurately reflect the actual operating capacity of the air conditioner under different operating conditions.

[0096] Step S300: Upon receiving the air conditioner capacity display control command, the cooling capacity or heating capacity of the air conditioner is displayed.

[0097] It is understandable that the air conditioner capacity display command can be a command issued by a remote control, mobile app, etc., a command triggered by the user pressing the physical or touch buttons on the air conditioner, an adjustment command received by the air conditioner's voice recognition module, or a display command triggered by a preset program or timer. Once a display command is received, the air conditioner capacity display device displays the cooling or heating capacity calculated in step S200 in real time on the air conditioner's display screen or other user interface devices (such as a mobile app, remote control display screen, etc.). This allows users to intuitively understand the current operating capacity of the air conditioner, thereby enabling them to more rationally adjust the use of the air conditioner to achieve optimal comfort and energy-saving effects.

[0098] In this embodiment, by acquiring indoor temperature, evaporator temperature, airflow rate of the air conditioner, and compressor operating parameters, the cooling or heating capacity of the air conditioner under the current operating conditions is calculated based on these parameters. Then, upon receiving an air conditioner capacity display control command, the cooling or heating capacity is displayed. Thus, by acquiring only indoor temperature, evaporator temperature, airflow rate, and compressor operating parameters, the cooling or heating capacity of the air conditioner can be calculated, reducing the number of parameters to be measured and the complexity of the calculation, improving calculation efficiency, and thus enhancing the convenience of air conditioner capacity display. Furthermore, the aforementioned indoor temperature, evaporator temperature, and airflow rate (compressor operating parameters) can all be monitored in real time by the air conditioner's built-in sensors or detection modules, eliminating the need for additional complex measuring equipment, thereby reducing air conditioner costs while increasing its integration.

[0099] In one possible implementation, the air conditioner further includes a fan. Please refer to [reference needed]. Figure 6 The steps for obtaining the air volume of the air conditioner include steps S110 to S120, wherein:

[0100] Step S110: Obtain the fan speed of the air conditioner, the maximum air volume of the air conditioner, and the maximum fan speed corresponding to the maximum air volume.

[0101] In this embodiment, the air conditioner's fan is a key component driving airflow, and its rotational speed directly affects the airflow volume. In this embodiment, the air conditioner's maximum airflow volume and the corresponding maximum fan speed can be obtained from the air conditioner's design specifications or experimental data. These parameters are typically determined during the product manufacturing stage and stored in the air conditioner's control system. In practical applications, the control system can indirectly calculate the current airflow volume by reading these preset parameters and monitoring the actual fan speed in real time.

[0102] Step S120: Calculate the air volume of the air conditioner based on the fan speed, the maximum fan speed, and the maximum air volume of the air conditioner.

[0103] In this embodiment, there is a certain proportional relationship between the air volume of the air conditioner and the fan speed. This relationship can be determined through experimental data or relevant parameters in the design specifications. Specifically, when the fan speed reaches its maximum, the air volume also reaches its maximum value, i.e., the maximum air volume. Therefore, the current fan speed can be mapped to the corresponding air volume using a proportionality factor or functional relationship to calculate the specific air volume value. This proportionality factor or functional relationship may be linear or non-linear, depending on the design characteristics and performance curves of the fan.

[0104] In one feasible implementation, step S120 can specifically calculate the air volume of the air conditioner using the following formula:

[0105] V = (B / A) × Vol;

[0106] Where V represents the air volume of the air conditioner, B represents the fan speed, A represents the maximum fan speed, and Vol represents the maximum air volume of the air conditioner.

[0107] In this embodiment, using this simplified calculation formula, we can quickly and accurately determine the current airflow of the air conditioner without the need for complex measuring equipment or additional data processing steps. This design not only improves computational efficiency but also reduces system complexity and cost. Furthermore, since all necessary parameters can be directly obtained from sensors or preset values ​​within the air conditioner, this calculation process boasts high reliability and real-time performance.

[0108] In one feasible implementation, please refer to Figure 2 The step S200 specifically includes step S210, which calculates the cooling capacity of the air conditioner based on the indoor temperature, evaporator temperature and air volume of the air conditioner when the current operating condition is cooling mode; and calculates the heating capacity of the air conditioner based on the indoor temperature, evaporator temperature, air volume of the air conditioner and compressor exhaust temperature when the current operating condition is heating mode.

[0109] In this embodiment, to more accurately calculate the air conditioner's capacity under different operating modes, different calculation strategies are adopted for cooling and heating. In cooling mode, since the primary goal is to lower the indoor temperature, the cooling capacity mainly depends on the efficiency of the evaporator in absorbing heat. By monitoring the indoor temperature, evaporator temperature, and airflow of the air conditioner in real time, we can construct an algorithm model specifically for cooling conditions to determine the heat exchange efficiency between the evaporator and the indoor air, as well as the impact of airflow on the heat transfer rate, thereby calculating the air conditioner's cooling capacity under the current cooling conditions.

[0110] In heating mode, the air conditioner primarily raises the indoor temperature, while the evaporator becomes a heat source, releasing heat into the room. The exhaust temperature directly reflects the compressor's efficiency and heat release capacity during heating. Therefore, in addition to considering basic parameters such as indoor temperature, evaporator temperature, and airflow, this embodiment also incorporates the compressor's exhaust temperature into a preset algorithm model or formula to more comprehensively evaluate the air conditioner's performance under heating conditions, thereby obtaining more accurate heating data.

[0111] In one feasible implementation, the compressor's operating parameters include the compressor discharge temperature. Please refer to... Figure 3 The step of calculating the cooling or heating capacity of the air conditioner under the current operating conditions based on the indoor temperature, evaporator temperature, air volume of the air conditioner, and compressor operating parameters specifically includes steps S210A1 and S210A3, wherein:

[0112] Step S210A1: Calculate the evaporator compensation temperature based on the compressor operating frequency and evaporator temperature. In this embodiment, since there is a certain temperature difference between the evaporator temperature and the actual outlet air temperature, and this temperature difference is affected by the compressor operating frequency, it is necessary to compensate for the evaporator temperature when calculating the cooling capacity or heating capacity to more accurately reflect the actual working state of the evaporator. Specifically, the evaporator compensation temperature can be calculated using a preset algorithm or formula, with the compressor operating frequency and evaporator temperature as input parameters. The purpose of this step is to eliminate the evaporator temperature measurement error caused by changes in the compressor operating frequency, thereby improving the accuracy of the cooling capacity or heating capacity calculation.

[0113] In one feasible implementation, in step S210A1, the evaporator compensation temperature can be calculated using the following formula:

[0114] T2^=T2-K1×((f1×Fr-f2) / f3);

[0115] Where T2^ represents the evaporator compensation temperature, T2 represents the evaporator temperature, Fr represents the compressor operating frequency, K1 represents the temperature compensation coefficient, and f1, f2, and f3 are preset constants.

[0116] In this embodiment, the temperature compensation coefficient K1 and the preset constants f1, f2, and f3 are all derived through statistical analysis of a large amount of experimental and historical data. These parameters effectively reflect the impact of the compressor's operating frequency on the evaporator temperature, ensuring the accuracy of the evaporator compensation temperature. By calculating the evaporator compensation, a value closer to the actual temperature at the air conditioner's outlet can be obtained, thereby improving the accuracy of the cooling or heating capacity calculation.

[0117] Step S210A3: Calculate the cooling capacity of the air conditioner based on the indoor temperature, the evaporator compensation temperature, and the air conditioner's airflow. In this embodiment, using the compensated evaporator temperature calculated in step S210A1, combined with the real-time monitored indoor temperature and the air conditioner's airflow, a preset algorithm model or formula is used to accurately calculate the air conditioner's cooling capacity under the current cooling conditions. Thus, this calculation model or formula comprehensively considers the heat exchange efficiency between the evaporator and indoor air, the impact of airflow on the heat transfer rate, and the accuracy improvement brought about by evaporator temperature compensation, thereby ensuring the accuracy and reliability of the cooling capacity data.

[0118] In one feasible implementation, in step S210A3, the cooling capacity of the air conditioner can be calculated using the following formula:

[0119] Q1 = KX × C × p × V × (T1 - T2^);

[0120] Where Q1 represents the cooling capacity of the air conditioner, T1 represents the indoor temperature, T2^ represents the evaporator compensation temperature, V represents the air volume of the air conditioner, C represents the specific heat capacity of the air, p represents the air density, and KX represents the cooling capacity calculation parameters.

[0121] In this embodiment, the cooling capacity calculation parameter KX is a comprehensive coefficient derived through multiple experiments and data analysis, taking into account various factors such as the air conditioner's cooling efficiency, evaporator material, refrigerant characteristics, and ambient temperature. It reflects the changes in the air conditioner's cooling capacity under different operating conditions, making the calculated cooling capacity more closely reflect actual usage. The air specific heat capacity C and air density p can be constant values ​​under standard atmospheric pressure, reflecting the air's ability to absorb heat and the mass of air per unit volume, respectively. Alternatively, they can be constant values ​​applicable to air conditioner capacity calculations in most regions. For example, the air specific heat capacity C can be set to 1.005 kJ / (kg·K), and the air density p to 1.16 kg / m³. 3 The specific heat capacity of air C and the air density p mentioned above can be fine-tuned according to actual usage or local environmental conditions to further improve the accuracy of cooling capacity calculation. In step S210A3, by substituting the indoor temperature T1, evaporator compensation temperature T2^, air volume V, specific heat capacity of air C, air density p, and cooling capacity calculation parameter KX into the above formula, the cooling capacity of the air conditioner under the current cooling condition can be quickly and accurately calculated. In this embodiment, the number of parameters required for air conditioner capacity calculation is small, the specific calculation formula is simple and easy to calculate, and the storage and calculation of the formula do not require a large amount of storage space in the air conditioner capacity display device, thereby improving the calculation efficiency of air conditioner capacity and thus improving the convenience of air conditioner capacity display.

[0122] In one feasible implementation, please refer to Figure 4 Before step S210A3, the air conditioner capacity display method further includes step S210A2, which adjusts the value of the cooling capacity calculation parameter based on the indoor temperature and the evaporator compensation temperature.

[0123] Understandably, in practical applications, the cooling capacity calculation parameter KX may need to be dynamically adjusted to adapt to different operating conditions due to changes in indoor environment and external conditions. Therefore, a step S210A2 is added before step S210A3 to fine-tune the cooling capacity calculation parameter KX based on the real-time monitored indoor temperature T1 and the compensated evaporator temperature T2^.

[0124] In step S210A2, the air conditioner capacity display device analyzes the combination of the current indoor temperature and the evaporator compensation temperature to determine whether they fall within a preset specific range. These ranges are divided based on a large amount of experimental data and historical statistical results. Each range corresponds to different cooling efficiency characteristics and operating conditions. The range can be set to two, three, four, or other numbers. The more ranges there are, the higher the accuracy and specificity of the division, and the more detailed the reflection of changes in cooling capacity under different operating conditions. Once the range of the current temperature and temperature compensation value is determined, the system adjusts the cooling capacity calculation parameter KX accordingly based on a preset mapping relationship or adjustment rule. This dynamic adjustment mechanism ensures that the cooling capacity calculation parameter KX always matches the current actual operating conditions, thereby improving the accuracy and adaptability of cooling capacity calculation. For example, when the indoor temperature is high and the evaporator compensation temperature is also high, the system may increase the value of KX to reflect the stronger cooling capacity of the air conditioner under high load conditions; conversely, when the indoor temperature is low and the evaporator compensation temperature is also low, the system may decrease the value of KX to reflect the relatively lower cooling demand of the air conditioner under low load conditions.

[0125] In this embodiment, through step S210A2, the entire air conditioner capacity display method not only considers the impact of evaporator temperature compensation on cooling capacity calculation, but also further considers the dynamic adjustment requirements of the cooling capacity calculation parameters due to changes in the combination of indoor temperature and evaporator temperature, thereby achieving a more comprehensive and accurate air conditioner capacity assessment.

[0126] In one specific implementation, step S210A2 includes:

[0127] When the difference between the indoor temperature and the evaporator compensation temperature is not less than 25℃, the cooling capacity calculation parameters are determined according to the following formula:

[0128] KX=K2×(1-d1(T1-T2^-d2))×(1-d3×V+d4)×d5;

[0129] When the difference between the indoor temperature and the evaporator compensation temperature is less than 25°C, the cooling capacity calculation parameters are determined according to the following formula:

[0130] KX = K3 × (1 - d3 × V + d4) × d5;

[0131] Where KX represents the cooling capacity calculation parameters, T1 represents the indoor temperature, T2^ represents the evaporator compensation temperature, V represents the air volume of the air conditioner, and d1, d2, d3, d4, and d5 are preset constants.

[0132] In this embodiment, by introducing temperature difference as a criterion in the specific implementation of step S210A2, the adjustment strategies for cooling capacity calculation parameters under different operating conditions can be more precisely defined. When the difference between the indoor temperature and the evaporator compensation temperature is not less than 25°C, it indicates that the air conditioner is facing a high load. At this time, adjusting the KX value through the formula not only considers the influence of temperature difference (non-linear adjustment of temperature difference through two constants d1 and d2), but also combines the factor of air volume V (linear adjustment through two constants d3 and d4), as well as a comprehensive adjustment factor d5, to achieve precise adjustment of cooling capacity calculation parameters under high load conditions. This design aims to more accurately reflect the cooling capacity of the air conditioner under high temperature difference and large air volume conditions, ensuring the accuracy of cooling capacity calculation.

[0133] When the difference between the indoor temperature and the evaporator compensation temperature is less than 25℃, a different formula is used to calculate the KX value. Although the influence of the air volume V is still considered, the nonlinear adjustment part directly related to the temperature difference is omitted because the temperature difference is relatively small at this time, and the air conditioner may be in a relatively stable operating state, without the need for overly complex adjustment strategies. This design simplifies the calculation process while ensuring the accuracy of cooling capacity calculation under low-load conditions. The preset constants d1, d2, d3, d4, and d5 are determined based on a large amount of experimental data and theoretical analysis. They represent the weight and degree of influence of different factors in the adjustment of cooling capacity calculation parameters. By adjusting the values ​​of these constants, the adaptability and accuracy of the cooling capacity calculation formula can be further optimized, making it more consistent with actual usage conditions.

[0134] In this embodiment, through the dynamic adjustment mechanism in step S210A2 and combined with the cooling capacity calculation formula in step S210A3, the air conditioner capacity display method of this embodiment not only considers the influence of evaporator temperature compensation and air volume on cooling capacity, but also dynamically adjusts the value of the cooling capacity calculation parameter KX by real-time monitoring of indoor temperature and evaporator compensation temperature, thereby achieving a comprehensive and accurate assessment of the air conditioner's cooling capacity under different operating conditions. This design not only improves the accuracy and adaptability of cooling capacity calculation, but also provides users with more reliable air conditioner capacity display information.

[0135] In one feasible implementation, the operating parameters of the compressor further include the compressor operating frequency. (Reference) Figure 5 The step of calculating the heating capacity of the air conditioner based on the indoor temperature, evaporator temperature, air outlet volume, and compressor exhaust temperature when the current operating condition is heating mode includes steps S210B1 to S210B3, wherein:

[0136] Step S210B1: Calculate the evaporator compensation temperature based on the compressor frequency and evaporator temperature. In this embodiment, similar to when the air conditioner is in cooling mode, there is a certain temperature difference between the evaporator temperature and the actual air outlet temperature. This temperature difference is affected by the compressor operating frequency. Therefore, when calculating the cooling capacity or heating capacity, it is necessary to compensate for the evaporator temperature to more accurately reflect the actual working state of the evaporator. Specifically, the evaporator compensation temperature can be calculated using a preset algorithm or formula, with the compressor operating frequency and evaporator temperature as input parameters. The purpose of this step is to eliminate the evaporator temperature measurement error caused by changes in the compressor operating frequency, thereby improving the accuracy of the cooling capacity or heating capacity calculation.

[0137] In one feasible implementation, in step S210A1, the evaporator compensation temperature can be calculated using the following formula:

[0138] T2^=T2-K1×((f1×Fr-f2) / f3);

[0139] Where T2^ represents the evaporator compensation temperature, T2 represents the evaporator temperature, Fr represents the compressor operating frequency, K1 represents the temperature compensation coefficient, and f1, f2, and f3 are preset constants.

[0140] In this embodiment, the temperature compensation coefficient K1 and the preset constants f1, f2, and f3 are all derived through statistical analysis of a large amount of experimental and historical data. These parameters effectively reflect the impact of the compressor's operating frequency on the evaporator temperature, ensuring the accuracy of the evaporator compensation temperature. By calculating the evaporator compensation, a value closer to the actual temperature at the air conditioner's outlet can be obtained, thereby improving the accuracy of the cooling or heating capacity calculation.

[0141] Step S210B2: Compensate the compressor exhaust temperature based on the preset temperature compensation model to obtain the compressor exhaust compensation temperature.

[0142] In this embodiment, since the temperature sensor for detecting the compressor exhaust temperature is generally located outside the compressor's exhaust pipe, there is a temperature difference between it and the refrigerant temperature inside, especially in heating mode where the refrigerant temperature is higher, this temperature difference may be more pronounced. Therefore, to improve the accuracy of the heating capacity calculation, it is necessary to compensate for the compressor exhaust temperature so that the compensated temperature is closer to the actual refrigerant temperature inside the compressor exhaust pipe. This step is based on a preset temperature compensation model, which considers various factors such as compressor operating frequency, ambient temperature, and condenser temperature. By comprehensively considering the influence of these factors, a more accurate compressor exhaust compensation temperature is obtained.

[0143] Step S210B3: Calculate the heating capacity of the air conditioner based on the indoor temperature, evaporator compensation temperature, air volume of the air conditioner, and compressor exhaust compensation temperature.

[0144] In this embodiment, the compensated evaporator temperature calculated in step S210B1, the compressor exhaust compensation temperature calculated in step S210B2, the indoor temperature, and the airflow of the air conditioner are used to accurately calculate the heating capacity of the air conditioner under the current cooling condition using a preset algorithm model or formula. Thus, this algorithm model or formula not only integrates the effects of the evaporator compensation temperature and the compressor exhaust compensation temperature, but also fully considers fluctuations in indoor temperature and changes in airflow, ensuring accurate heating capacity assessment under various heating conditions. Especially under extreme weather conditions, such as severe winters, when the difference between indoor temperature and the set temperature is large, accurately calculating the evaporator compensation temperature and the compressor exhaust compensation temperature can effectively avoid underestimating or overestimating the heating capacity, providing users with a more comfortable indoor temperature environment.

[0145] In one feasible implementation, in step S210B3, the heating capacity of the air conditioner can be determined according to the following formula:

[0146] Q2=KM×C×p×V×(e1×T2^+e2×Tp^-T1)×e3;

[0147] Where Q2 represents the heating capacity of the air conditioner, T1 represents the indoor temperature, T2^ represents the evaporator compensation temperature, V represents the air volume of the air conditioner, C represents the specific heat capacity of the air, p represents the air density, Tp^ represents the compressor exhaust compensation temperature, KM represents the heating capacity calculation parameters, and e1, e2, and e3 are preset constants.

[0148] In this embodiment, the setting of the heating capacity calculation parameter KM is also based on extensive experimental verification and theoretical analysis, aiming to accurately reflect the comprehensive impact of various factors on heating capacity. KM not only includes the inherent performance parameters of the air conditioner design, but also integrates considerations such as material thermal conductivity, heat exchange efficiency, and refrigerant thermodynamic properties. By continuously adjusting and optimizing the KM value, it can be ensured that the heating capacity calculation model maintains high accuracy and reliability under various operating conditions. The evaporator compensation temperature T2^ is directly related to the heat exchange efficiency between the evaporator and indoor air, while the compressor exhaust compensation temperature Tp^ reflects the impact of the compressor's operating state on the heating effect. The air volume directly determines the amount of air passing through the air conditioner per unit time, thus affecting the heating capacity output. The specific heat capacity C and density p of air are basic parameters describing the thermophysical properties of air, and their accurate values ​​are also crucial for heating capacity calculation. The preset constants e1, e2, e3, etc. in the formula are empirical values ​​obtained by fitting a large amount of experimental data, used to adjust the weight of each parameter in the heating capacity calculation, so that the calculation results are more consistent with the actual situation.

[0149] The air conditioner capacity display method in this embodiment, in heating mode, comprehensively and accurately assesses the air conditioner's heating capacity by considering multiple factors, including evaporator compensation temperature, compressor exhaust compensation temperature, indoor temperature, air volume, and heating capacity calculation parameters. This improves the accuracy and adaptability of heating capacity calculation, providing users with more reliable air conditioner performance reference information.

[0150] In one possible implementation, the air conditioner includes a display screen and / or a wireless communication module, the wireless communication module being used for communicative connection with the display device. (Reference) Figure 7 Step S300 includes step S310, whereby, upon receiving an air conditioner capacity display control command, the cooling capacity or heating capacity of the air conditioner is displayed on the display screen; and / or, upon receiving an air conditioner capacity display control command, the cooling capacity or heating capacity of the air conditioner is sent to the display device for display on the display device.

[0151] In this embodiment, the user can send air conditioner capacity display control commands via remote control, mobile app, or the touch panel on the air conditioner. When the air conditioner receives the air conditioner capacity display control command, it will display the calculated cooling or heating capacity.

[0152] In this embodiment, if the air conditioner is equipped with a display screen, it can directly show the current cooling or heating capacity on the screen, providing users with a clear overview. This display method is intuitive and immediate, allowing users to easily monitor the air conditioner's operating status and performance. Furthermore, for air conditioners that support wireless communication, they can also transmit cooling or heating capacity information to a connected display device, such as a smartphone, tablet, or smart home control center, via a wireless communication module. This allows users to understand the air conditioner's performance status even when they are not near it.

[0153] In one feasible implementation, refer to Figure 8 The step of displaying the cooling or heating capacity of the air conditioner on the display screen when the air conditioner capacity display control command is received includes steps S311 to S313, wherein:

[0154] Step S311: Obtain the number of digits of the numerical value that the display screen can display.

[0155] Understandably, different displays have varying maximum number of digits they can show due to their physical characteristics and design limitations. To ensure the accuracy and readability of the displayed content, we first need to understand the display capacity of the current screen, that is, the number of digits of the numerical value it can display completely. If the air conditioner's cooling or heating capacity can be fully displayed on the screen, then we can directly display the air conditioner's cooling or heating capacity. However, if the display capacity is insufficient to fully display the cooling or heating capacity, then corresponding measures need to be taken to ensure the effective transmission of the air conditioner's cooling or heating capacity.

[0156] Step S312: When the number of digits of the value that the display screen can display does not meet the preset display range, adjust the display accuracy of the cooling capacity or heating capacity.

[0157] In this embodiment, when the number of digits displayed on the screen does not meet the preset full display range, the air conditioner automatically adjusts the display accuracy of the cooling or heating capacity to ensure that the user can clearly read key information. Specifically, the air conditioner analyzes the currently calculated cooling or heating capacity and, based on the display screen's capabilities, adjusts the displayed value using scientific decimal shifting, displaying only the major digits, or rounding. For example, if the screen can only display four digits, and the calculated cooling capacity is 12345W, the air conditioner can adjust it to 12.35kW for display, preserving key information while ensuring the accuracy and readability of the value. As another example, if the calculated cooling capacity is 3500W, but the screen can only display three digits, the air conditioner can adjust it to 350W for display; and as yet another example, if the calculated cooling capacity is 3486W, but the screen can only display three digits, the air conditioner can first round the cooling capacity to 3490W, and then further adjust it to 349W for display.

[0158] Step S313: The adjusted cooling or heating capacity is displayed on the screen to make the air conditioner's capabilities readable on the screen. In this embodiment, by adjusting the display accuracy, the air conditioner presents the optimized cooling or heating capacity value on the screen, ensuring the readability and accuracy of the information.

[0159] In one feasible implementation, after step S300, the method further includes steps S410 to S420, wherein:

[0160] Step S410: Obtain the air conditioner adjustment command.

[0161] As is understandable, air conditioner adjustment commands are used to adjust the air conditioner's operating status and parameters. These commands may include various types such as temperature setting, fan speed adjustment, and mode switching (e.g., cooling, heating, dehumidification, and ventilation). Users can send these commands to the air conditioner through various means such as remote control, mobile app, and touch panel to adjust the air conditioner's operating status and thus meet the needs of different usage scenarios.

[0162] Step S420: Adjust the operating parameters of the air conditioner according to the air conditioner adjustment command, and display the cooling capacity or heating capacity corresponding to the adjusted operating parameters.

[0163] In this embodiment, upon receiving an air conditioner adjustment command, the air conditioner's control system responds immediately and parses the specific content of the command. For example, if the command requests switching the air conditioner from cooling mode to heating mode and setting the target temperature to 25°C, the control system will first change the air conditioner's operating mode and adjust the operating status of key components such as the compressor and fan to adapt to the heating demand. Simultaneously, based on the new operating mode and target temperature, the system will recalculate the current heating capacity and prepare to display this information to the user. During the adjustment of operating parameters, the air conditioner will monitor various key indicators in real time, such as compressor exhaust temperature, evaporator temperature, and indoor temperature, to ensure stable system operation and achieve the user-set target. This monitoring data will also be used to update the calculation of heating or cooling capacity to reflect the air conditioner's current actual performance. After completing the adjustment of operating parameters, the air conditioner will execute the display processing flow again. At this time, because the operating mode, set temperature, and other conditions have changed, the calculated heating capacity will also change accordingly. The system will adjust the display accuracy again based on the new heating capacity and the display screen's display capabilities to ensure that the current heating information is clearly and accurately displayed on the screen.

[0164] In this embodiment, by acquiring the indoor temperature, evaporator temperature, airflow rate of the air conditioner, and compressor operating parameters, the cooling or heating capacity of the air conditioner under the current operating conditions is calculated based on these parameters. Then, upon receiving an air conditioner capacity display control command, the cooling or heating capacity of the air conditioner is displayed. Thus, by acquiring only the indoor temperature, evaporator temperature, airflow rate, and compressor operating parameters, the cooling or heating capacity of the air conditioner can be calculated, reducing the number of parameters to be measured and the complexity of the calculation, improving calculation efficiency, and thereby enhancing the convenience of air conditioner capacity display.
