[0036] Figure 1 is a schematic diagram of a method for correcting air conditioner selection data provided by an embodiment of the present disclosure; Figure 1 As shown, the embodiment of the present disclosure provides a method for correcting air conditioner selection data, comprising:

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

[0038] S12, the server determines a corrected evaporation temperature and a corrected condensation temperature according to 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 according to the corrected evaporation temperature and the corrected condensation temperature.

[0040] In this solution, the server can be a cloud server, and the server can also be arranged in the air conditioner. Specifically, the server can obtain the inlet water temperature of the air conditioner heat exchanger and the outlet water temperature of the air conditioner heat exchanger through temperature sensors arranged in different positions of 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 conditioning cooling capacity * 1000 ÷ total heat transfer coefficient ÷ heat exchange area of ​​the evaporator; the logarithmic mean temperature difference of the condenser = air conditioning 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 of the outer side of the tube, the metal thermal resistance, the outer diameter of the tube and the inner diameter of the tube can be obtained by conventional calculations, and will not be described in detail here; the heat transfer coefficient inside the tube is determined by the refrigerant type. As an example, the heat transfer coefficient inside the tube corresponding to the refrigerant type can be matched in the heat transfer database to accurately obtain the heat transfer coefficient inside the tube.

[0043] Furthermore, the server determines the corrected evaporation temperature and the corrected condensation temperature according to 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: the server determines the required refrigerant approach temperature difference of the air conditioner heat exchanger according to 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; the server determines the corrected evaporation temperature and the corrected condensation temperature according to the required refrigerant approach temperature difference of the air conditioner heat exchanger. In this way, the corrected evaporation temperature and the corrected condensation temperature can be accurately determined in combination with the required refrigerant approach temperature difference.

[0044] Furthermore, the server determines the corrected air conditioner selection data according to the corrected evaporation temperature and the corrected condensation temperature, including: the server obtains the operation database; the server matches the air conditioner selection data associated with the corrected evaporation temperature and the corrected condensation temperature in the operation database, and uses it 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 by the embodiment of the present disclosure is adopted, by obtaining the water inlet temperature of the air conditioner heat exchanger, the water outlet temperature of the air conditioner heat exchanger and the logarithmic mean temperature difference; according to the water inlet temperature of the air conditioner heat exchanger, the water outlet temperature of the air conditioner heat exchanger and the logarithmic mean temperature difference, the corrected evaporation temperature and the corrected condensation temperature are determined; according to the corrected evaporation temperature and the corrected condensation temperature, the corrected air conditioner selection data is determined. With this scheme, the air conditioner selection data can be corrected according to the corrected evaporation temperature and the corrected condensation temperature, so as to obtain more accurate air conditioner selection data, so that users can refer to the corrected air conditioner selection data to select air conditioners, effectively improving the accuracy of air conditioner selection results, and reasonably reducing the selection preparation workload while improving the air conditioner selection efficiency.

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

[0047] S21, the server determines the required refrigerant of the air conditioner heat exchanger to be close to the temperature difference value according to 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.

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

[0049] In this solution, the demand refrigerant approach temperature difference of the air-conditioning heat exchanger includes the demand refrigerant approach temperature difference of the evaporator and the demand refrigerant approach temperature difference of the condenser. Specifically, the service end can obtain the demand refrigerant approach temperature difference of the evaporator in combination with 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 of the evaporator; and obtain the demand refrigerant approach temperature difference of the condenser in combination with 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 of the condenser. In this way, the demand refrigerant approach temperature difference of the evaporator and the demand refrigerant approach temperature difference of the condenser can be accurately obtained.

[0050] Furthermore, the server can determine the corrected evaporation temperature and the corrected condensation temperature based on the required refrigerant temperature difference of the evaporator and the required refrigerant temperature difference of the condenser, providing an accurate data basis for the correction of air conditioning selection data.

[0051] Figure 3 is a schematic diagram of a method for determining a required refrigerant temperature difference provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, in S21, the server determines the required refrigerant of the air conditioner heat exchanger according to 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:

[0052] S31, the server calculates the approximate temperature difference of the required refrigerant and the approximate temperature difference of the pure water according to 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 approximate temperature difference of the required refrigerant and the approximate temperature difference of pure water as the approximate temperature difference 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 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 required refrigerant can be calculated in the following way:

[0055]

[0056] Among them, the service end can match the in-tube heat transfer coefficient corresponding to the demand refrigerant in combination with the type of demand refrigerant, thereby inputting the in-tube heat transfer coefficient corresponding to the demand refrigerant into the calculation formula of the total heat transfer coefficient to obtain the total heat transfer coefficient of the demand refrigerant; and then inputting the calculated total heat transfer coefficient of the demand refrigerant into the aforementioned calculation formula of the logarithmic mean temperature difference of the heat exchanger to calculate the logarithmic mean temperature difference of the refrigerant of the heat exchanger to the demand refrigerant. Further, the calculated logarithmic mean temperature difference of the refrigerant of the heat exchanger to the demand refrigerant can be input into the formula of the approach temperature difference of the demand refrigerant to calculate the approach temperature difference of the demand refrigerant. It can be understood that the aforementioned formula can be used to calculate the approach temperature difference of the demand refrigerant of the air conditioner evaporator and the approach temperature difference of the demand refrigerant of the air conditioner condenser respectively.

[0057] Similarly, the server calculates 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. As an example, the approximate temperature difference of pure water can be calculated in the following way:

[0058]

[0059] Among them, when the refrigerant is pure water, the service end can match the in-tube heat transfer coefficient corresponding to pure water, thereby inputting the in-tube heat transfer coefficient corresponding to pure water into the calculation formula of the total heat transfer coefficient to obtain the total heat transfer coefficient of pure water; and then inputting the calculated total heat transfer coefficient of pure water into the calculation formula of the logarithmic mean temperature difference of the aforementioned heat exchanger, the logarithmic mean temperature difference of the refrigerant of the heat exchanger as pure water can be calculated. Further, the calculated logarithmic mean temperature difference of the refrigerant of the heat exchanger as pure water can be input into the formula of the approach temperature difference of pure water to calculate the approach temperature difference of pure water. It can be understood that the aforementioned formula can be used to calculate the approach temperature difference of the pure water of the air conditioner evaporator and the approach temperature difference of the pure water of the air conditioner condenser respectively. With this scheme, the approach temperature difference of the required refrigerant and the approach temperature difference of pure water can be accurately calculated.

[0060] Furthermore, the service end determines the difference between the approach temperature difference of the demand refrigerant and the approach temperature difference of the pure water as the approach temperature difference difference of the demand refrigerant. Specifically, in this solution, if the heat exchanger is an evaporator, the approach temperature difference difference of the demand refrigerant of the air-conditioning evaporator = the approach temperature difference of the demand refrigerant of the air-conditioning evaporator - the approach temperature difference of the pure water of the air-conditioning evaporator; if the heat exchanger is a condenser, the approach temperature difference difference of the demand refrigerant of the air-conditioning condenser = the approach temperature difference of the demand refrigerant of the air-conditioning condenser - the approach temperature difference of the pure water of the air-conditioning condenser. In this way, accurate calculation of the approach temperature difference difference of the demand refrigerant can be achieved.

[0061] Figure 4 is another schematic diagram of a method for correcting air conditioner selection data provided by an embodiment of the present disclosure; Figure 4As shown, optionally, in S22, the server determines the corrected evaporation temperature according to the temperature difference of the refrigerant required by 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 difference between the current evaporating temperature and the required refrigerant approximate temperature difference of the air conditioner evaporator as the corrected evaporating temperature.

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

[0065] Figure 4 is another schematic diagram of a method for correcting air conditioner selection data provided by an embodiment of the present disclosure; Figure 4 As shown, optionally, in S22, the server determines the corrected condensing temperature according to the temperature difference of the required refrigerant 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 sum of the current condensing temperature and the required refrigerant approximate temperature difference of the air conditioner condenser as the corrected condensing temperature.

[0068] In this solution, the server can collect the current condensing temperature through the temperature sensor set on the condenser, and determine the sum of the current condensing temperature and the difference in the required refrigerant temperature approach of the air conditioner condenser as the corrected condensing temperature. That is, the corrected condensing temperature = the current condensing temperature + the difference in the required refrigerant temperature approach of the air conditioner condenser. In this way, the corrected condensing temperature can be accurately calculated by combining the current condensing temperature and the difference in the required refrigerant temperature approach of the air conditioner condenser.

[0069] Figure 5 is a schematic diagram of a method for determining corrected air conditioner selection data provided by an embodiment of the present disclosure; Figure 5 As shown, optionally, in S13, the server determines the corrected air conditioner selection data according to the corrected evaporation temperature and the corrected condensation temperature, including:

[0070] S51, the server obtains an operation database, which stores the association 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 operation database, and uses the matched air conditioner selection data as the corrected air conditioner selection data.

[0072] In this solution, the server can obtain an operation database, which stores the association between the evaporation temperature, the condensation temperature and the air conditioner selection data. Furthermore, the server can match the air conditioner selection data associated with the corrected evaporation temperature and the corrected condensation temperature in the operation database, and use it as the corrected air conditioner selection data. Among them, the air conditioner selection data includes cooling capacity, power, etc. With this solution, the air conditioner selection data can be determined based on the corrected evaporation temperature and the corrected condensation temperature, thereby ensuring the accuracy of the air conditioner selection data.

[0073] Figure 6 is a schematic diagram of a method for determining corrected resistance loss data provided by an embodiment of the present disclosure; Figure 6 As shown, optionally, after obtaining the water inlet temperature of the air-conditioning heat exchanger, the water outlet temperature of the air-conditioning heat exchanger and the logarithmic mean temperature difference, it also 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 coefficient according to the resistance loss of the required refrigerant and the resistance loss of pure water.

[0076] S63, the server determines the corrected resistance loss data according to the resistance loss correction coefficient.

[0077] In this solution, the server can also calculate the resistance loss of the demand refrigerant and the resistance loss of pure water through the pre-stored heat transfer formula; thus, the resistance loss correction coefficient can be calculated in combination with the resistance loss of the demand refrigerant and the resistance loss of pure water. Specifically, the resistance loss correction coefficient = the resistance loss of the demand refrigerant / the resistance loss of pure water. In this way, the resistance loss correction coefficient can be accurately determined in combination with the resistance loss of the demand refrigerant and the resistance loss of pure water.

[0078] Furthermore, the server can determine the corrected resistance loss data in combination with the resistance loss correction coefficient. 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.
