[0036] Figure 1 This is a schematic diagram of a method for correcting air conditioner selection data provided in an embodiment of this disclosure; combined with Figure 1 As shown in the embodiments of this disclosure, a method for correcting air conditioner selection data is provided, including:

[0037] S11, the server obtains the inlet water temperature, outlet water temperature and logarithmic mean temperature difference of the air conditioner heat exchanger.

[0038] S12, the server determines the corrected evaporation temperature and the corrected condensation temperature based on the inlet water temperature of the air conditioner heat exchanger, the outlet water temperature of the air conditioner heat exchanger, and the logarithmic mean temperature difference.

[0039] S13, the server determines the corrected air conditioner selection data based on the corrected evaporation temperature and the corrected condensation temperature.

[0040] In this solution, the server can be a cloud server or it can be deployed in the air conditioner. Specifically, the server can obtain the inlet water temperature and outlet water temperature of the air conditioner heat exchanger through temperature sensors deployed at different locations in the air conditioner. Here, the inlet water temperature of the air conditioner heat exchanger includes the inlet water temperature of the evaporator and the inlet water temperature of the condenser, and the outlet water temperature of the air conditioner heat exchanger includes the outlet water temperature of the evaporator and the outlet water temperature of the condenser. In this embodiment, the logarithmic mean temperature difference includes the logarithmic mean temperature difference of the evaporator and the logarithmic mean temperature difference of the condenser. Specifically, the logarithmic mean temperature difference of the evaporator = air conditioner cooling capacity * 1000 ÷ total heat transfer coefficient ÷ heat exchange area of ​​the evaporator; the logarithmic mean temperature difference of the condenser = air conditioner cooling capacity * 1000 ÷ total heat transfer coefficient ÷ heat exchange area of ​​the condenser. As an example, the total heat transfer coefficient can be determined in the following way:

[0041]

[0042] Here, the heat transfer coefficient on the outside of the pipe, the thermal resistance of the metal, the outer diameter of the pipe, and the inner diameter of the pipe can be obtained through conventional calculations, which will not be elaborated here; the heat transfer coefficient inside the pipe is determined by the type of refrigerant. As an example, the heat transfer coefficient inside the pipe corresponding to the type of refrigerant can be matched in the heat transfer database to accurately obtain the heat transfer coefficient inside the pipe.

[0043] Furthermore, the server determines the corrected evaporation temperature and corrected condensation temperature based on the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the air conditioner heat exchanger. This includes: the server determining the required refrigerant near-temperature difference of the air conditioner heat exchanger based on the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference; and the server determining the corrected evaporation temperature and corrected condensation temperature based on the required refrigerant near-temperature difference. In this way, by combining the required refrigerant near-temperature difference, the corrected evaporation temperature and corrected condensation temperature can be accurately determined.

[0044] Furthermore, the server determines the corrected air conditioner selection data based on the corrected evaporation temperature and the corrected condensation temperature. This includes: the server obtaining the operating database; the server matching the air conditioner selection data associated with the corrected evaporation temperature and the corrected condensation temperature in the operating database, and using this as the corrected air conditioner selection data. In this way, accurate correction of the air conditioner selection data is achieved.

[0045] The method for correcting air conditioner selection data provided in this disclosure involves acquiring the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the air conditioner heat exchanger; determining the corrected evaporation temperature and corrected condensation temperature based on these parameters; and finally, determining the corrected air conditioner selection data based on these temperatures. This method corrects the air conditioner selection data according to the corrected evaporation and condensation temperatures, resulting in more accurate data for users to use. This effectively improves the accuracy of air conditioner selection results, increases selection efficiency, and reasonably reduces the workload of preparation.

[0046] Figure 2 This is a schematic diagram of another method for correcting air conditioner selection data provided in this disclosure embodiment; combined with Figure 2 As shown, optionally, in S12, the server determines the corrected evaporation temperature and the corrected condensation temperature based on the inlet water temperature of the air conditioner heat exchanger, the outlet water temperature of the air conditioner heat exchanger, and the logarithmic mean temperature difference, including:

[0047] S21, the server determines the required refrigerant temperature difference of the air conditioner heat exchanger based on the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the air conditioner heat exchanger.

[0048] S22, the server determines the corrected evaporation temperature and the corrected condensation temperature based on the refrigerant temperature difference required by the air conditioner heat exchanger.

[0049] In this solution, the refrigerant proximity temperature difference for the air conditioning heat exchanger includes both the refrigerant proximity temperature difference for the evaporator and the refrigerant proximity temperature difference for the condenser. Specifically, the server can obtain the refrigerant proximity temperature difference for the evaporator by combining the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the evaporator; and obtain the refrigerant proximity temperature difference for the condenser by combining the same conditions. This method enables accurate acquisition of the refrigerant proximity temperature differences for both the evaporator and the condenser.

[0050] Furthermore, the server can determine the corrected evaporation temperature and the corrected condensation temperature by combining the refrigerant temperature difference between the evaporator and the condenser, providing a precise data basis for correcting air conditioner selection data.

[0051] Figure 3 This is a schematic diagram of a method for determining the temperature difference between near-refrigerant requirements, provided in an embodiment of this disclosure; combined with Figure 3 As shown, optionally, in S21, the server determines the required refrigerant approximation temperature difference of the air conditioning heat exchanger based on the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the air conditioning heat exchanger, including:

[0052] S31, the server calculates the approximate temperature difference of the required refrigerant and the approximate temperature difference of pure water based on the inlet water temperature of the air conditioner heat exchanger, the outlet water temperature of the air conditioner heat exchanger, and the logarithmic mean temperature difference.

[0053] S32, the server determines the difference between the near temperature difference of the required refrigerant and the near temperature difference of pure water as the near temperature difference of the required refrigerant.

[0054] In this solution, the server calculates the approximate temperature difference of the required refrigerant based on the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the air conditioner heat exchanger. As an example, the approximate temperature difference of the required refrigerant can be calculated as follows:

[0055]

[0056] The server can match the required refrigerant type to the corresponding in-pipe heat transfer coefficient, and then input this coefficient into the formula for calculating the overall heat transfer coefficient to obtain the overall heat transfer coefficient for the required refrigerant. Furthermore, the calculated overall heat transfer coefficient is input into the aforementioned formula for calculating the logarithmic mean temperature difference of the heat exchanger, allowing the calculation of the logarithmic mean temperature difference of the heat exchanger when the refrigerant is the required refrigerant. Further, the calculated logarithmic mean temperature difference of the heat exchanger when the refrigerant is the required refrigerant can be input into the formula for calculating the approximate temperature difference of the required refrigerant to obtain the approximate temperature difference of the required refrigerant. Understandably, the aforementioned formulas can be used to calculate the approximate temperature difference of the required refrigerant for the air conditioner evaporator and the air conditioner condenser, respectively.

[0057] Similarly, the server calculates the approximate temperature difference of the pure water based on the inlet water temperature of the air conditioner heat exchanger, the outlet water temperature of the air conditioner heat exchanger, and the logarithmic mean temperature difference. As an example, the approximate temperature difference of the pure water can be calculated in the following way:

[0058]

[0059] The server can match the corresponding in-pipe heat transfer coefficient when the refrigerant is pure water. This coefficient is then input into the formula for calculating the overall heat transfer coefficient to obtain the total heat transfer coefficient for pure water. Furthermore, the calculated total heat transfer coefficient for pure water is input into the aforementioned formula for calculating the logarithmic mean temperature difference of the heat exchanger when the refrigerant is pure water, thus calculating the logarithmic mean temperature difference of the heat exchanger when the refrigerant is pure water. Further, the calculated logarithmic mean temperature difference of the heat exchanger when the refrigerant is pure water can be input into the formula for calculating the approximate temperature difference of pure water to obtain the approximate temperature difference of pure water. Understandably, the aforementioned formulas can be used to calculate the approximate temperature difference of pure water in the air conditioner evaporator and the air conditioner condenser, respectively. This solution allows for the accurate calculation of the approximate temperature difference of the required refrigerant and the approximate temperature difference of pure water.

[0060] Furthermore, the server defines the difference between the approximate temperature difference of the required refrigerant and the approximate temperature difference of pure water as the required refrigerant approximate temperature difference. Specifically, in this solution, if the heat exchanger is an evaporator, then the required refrigerant approximate temperature difference of the air conditioner evaporator = the required refrigerant approximate temperature difference of the air conditioner evaporator - the approximate temperature difference of pure water in the air conditioner evaporator; if the heat exchanger is a condenser, then the required refrigerant approximate temperature difference of the air conditioner condenser = the required refrigerant approximate temperature difference of the air conditioner condenser - the approximate temperature difference of pure water in the air conditioner condenser. In this way, accurate calculation of the required refrigerant approximate temperature difference can be achieved.

[0061] Figure 4 This is a schematic diagram of another method for correcting air conditioner selection data provided in this disclosure embodiment; combined with Figure 4As shown, optionally, in step S22, the server determines the corrected evaporation temperature based on the required refrigerant temperature difference of the air conditioner heat exchanger, including:

[0062] S411, the server obtains the current evaporation temperature of the air conditioner evaporator.

[0063] S412, the server determines the corrected evaporation temperature as the difference between the current evaporation temperature and the temperature difference between the refrigerant required by the air conditioner evaporator.

[0064] In this solution, the server can collect the current evaporation temperature using a temperature sensor installed on the evaporator, and determine the corrected evaporation temperature as the difference between the current evaporation temperature and the near-temperature difference of the refrigerant required by the air conditioner evaporator. That is, the corrected evaporation temperature = current evaporation temperature - near-temperature difference of the refrigerant required by the air conditioner evaporator. In this way, the corrected evaporation temperature can be accurately calculated by combining the current evaporation temperature and the near-temperature difference of the refrigerant required by the air conditioner evaporator.

[0065] Figure 4 This is a schematic diagram of another method for correcting air conditioner selection data provided in this disclosure embodiment; combined with Figure 4 As shown, optionally, in step S22, the server determines the corrected condensing temperature based on the required refrigerant temperature difference of the air conditioner heat exchanger, including:

[0066] S421, the server obtains the current condensing temperature of the air conditioner condenser.

[0067] S422, the server determines the corrected condensing temperature by summing the current condensing temperature with the difference between the current condensing temperature and the temperature difference between the required refrigerant temperature of the air conditioner condenser.

[0068] In this solution, the server can collect the current condensing temperature using a temperature sensor installed on the condenser, and determine the corrected condensing temperature by summing the current condensing temperature with the difference between the current condensing temperature and the near-current refrigerant temperature difference required by the air conditioner condenser. That is, the corrected condensing temperature = current condensing temperature + near-current refrigerant temperature difference required by the air conditioner condenser. In this way, the corrected condensing temperature can be accurately calculated by combining the current condensing temperature and the near-current refrigerant temperature difference required by the air conditioner condenser.

[0069] Figure 5 This is a schematic diagram of a method for determining corrected air conditioner selection data provided in an embodiment of this disclosure; combined with Figure 5 As shown, optionally, in step S13, the server determines the corrected air conditioner selection data based on the corrected evaporation temperature and the corrected condensation temperature, including:

[0070] S51, the server obtains the running database, which stores the correlation between evaporation temperature, condensation temperature and air conditioner selection data.

[0071] S52, the server matches the air conditioner selection data associated with the corrected evaporation temperature and the corrected condensation temperature in the running database, and uses it as the corrected air conditioner selection data.

[0072] In this solution, the server obtains an operational database that stores the correlation between evaporation temperature, condensation temperature, and air conditioner selection data. Furthermore, the server can match the air conditioner selection data associated with the corrected evaporation temperature and condensation temperature from the operational database and use this as the corrected air conditioner selection data. This air conditioner selection data includes cooling capacity, power, etc. This solution enables the determination of air conditioner selection data based on the corrected evaporation temperature and condensation temperature, ensuring the accuracy of the air conditioner selection data.

[0073] Figure 6 This is a schematic diagram of a method for determining corrected drag loss data provided in an embodiment of this disclosure; combined with Figure 6 As shown, optionally, after obtaining the inlet water temperature of the air conditioning heat exchanger, the outlet water temperature of the air conditioning heat exchanger, and the logarithmic mean temperature difference, the method further includes:

[0074] S61, the server calculates the resistance loss of the required refrigerant and the resistance loss of pure water.

[0075] S62, the server calculates the resistance loss correction factor based on the resistance loss of the required refrigerant and the resistance loss of pure water.

[0076] S63, the server determines the corrected resistance loss data based on the resistance loss correction coefficient.

[0077] In this solution, the server can also calculate the resistance loss of the required refrigerant and the resistance loss of pure water using pre-stored heat transfer formulas. This allows for the calculation of a resistance loss correction factor based on these two factors. Specifically, the resistance loss correction factor = resistance loss of required refrigerant / resistance loss of pure water. This method enables the accurate determination of the resistance loss correction factor by combining the resistance losses of the required refrigerant and pure water.

[0078] Furthermore, the server can combine the resistance loss correction coefficient to determine the corrected resistance loss data. Specifically, the server can obtain the current resistance loss data of the air conditioner; the air conditioner uses the product of the current resistance loss data and the resistance loss correction coefficient as the corrected resistance loss data. In this way, the resistance loss data can be corrected more accurately.

[0080] The apparatus for correcting air conditioner selection data provided in this embodiment acquires the inlet water temperature, outlet water temperature, and logarithmic mean temperature difference of the air conditioner heat exchanger. Based on these temperatures, the corrected evaporation temperature and corrected condensation temperature are determined. Finally, the corrected air conditioner selection data is determined based on these temperatures.

This effectively improves the accuracy of air conditioner selection results, increases selection efficiency, and reasonably reduces the workload of preparation.
