If the mode type is cooling and the first difference is less than the lower limit of the preset tolerance range, or if the mode type is heating and the first difference is greater than the upper limit of the preset tolerance range, the adjustment value is determined by calculation based on the second parameter and the initial operating parameters.

[0009] In some embodiments, the step of calculating and determining the stable operating time based on the first difference, the third preset threshold group, and the preset tolerance range specifically includes: The preset tolerance range is analyzed to determine the tolerance value, and the absolute value of the first difference, the tolerance value, and the third preset threshold group are compared; wherein, the third preset threshold group includes a first temperature threshold and a second temperature threshold. If the absolute value of the first difference is less than the allowable tolerance value, maintain the current state; If the absolute value of the first difference is greater than or equal to the allowable value, and the absolute value of the first difference is less than the first temperature threshold, the first preset duration is used to determine the stable operation duration. If the absolute value of the first difference is greater than or equal to the first temperature threshold, and the absolute value of the first difference is less than the second temperature threshold, the second preset duration is used to determine the stable operation duration.

[0024] Figure 1This is an optional flowchart of an air conditioning constant temperature air supply control method provided in the embodiments of this application. Figure 1 The method may include, but is not limited to, steps S101 to S103.

[0025] Step S101: Obtain the current air outlet temperature, current operating mode, current indoor temperature and current outdoor temperature; calculate the difference between the current air outlet temperature and the preset target air outlet temperature to determine the first difference; and compare the first difference with the preset tolerance range. Step S102: If the first difference is within the preset tolerance range, maintain the current state; Step S103: If the first difference is outside the preset tolerance range, determine the control parameters based on the first difference, the current operating mode, the preset tolerance range, the current indoor temperature, and the current outdoor temperature, and adjust the air conditioner according to the control parameters.

[0026] Steps S101 to S103 of this embodiment involve: real-time acquisition of the current air outlet temperature by sensors installed in the air conditioner; acquisition of the current indoor and outdoor temperatures by temperature sensors; and determination of the current operating mode of the air conditioner by accessing the air conditioner system. The current air outlet temperature is calculated and compared with the set target air outlet temperature to determine the air outlet temperature difference. Then, the calculated air outlet temperature difference is compared with a pre-set error tolerance range to determine whether the air outlet temperature difference falls within the error tolerance range, thereby determining whether the air conditioner's operating parameters need adjustment to meet the user's comfort requirements. If the air outlet temperature difference falls within the error tolerance range, it indicates that the current air conditioner's air outlet temperature has a certain error, but it is within the user's acceptable range. If the air outlet temperature difference falls outside the error tolerance range, the control device calculates the adjustment parameters of the air conditioner using the real-time acquired outdoor and indoor temperatures, and adjusts the parameters of the air conditioner's compressor and built-in fan according to the determined adjustment parameters, thereby adjusting the air conditioner's air outlet temperature so that the error between it and the target air outlet temperature falls within the error tolerance range or equals the target air outlet temperature, thus achieving constant temperature air supply and meeting the user's comfort needs.

[0027] In this embodiment, the candidate parameter set includes several initial operating frequencies of the compressor at the current outdoor temperature, determined by the system through outer loop control logic, as well as the initial and lower limit values ​​of the fan speed corresponding to the several initial operating frequencies; The initial operating parameters include the compressor initial frequency corresponding to the current indoor temperature, determined by the inner loop control logic after the system determines the candidate parameter group, as well as the initial and lower limit values ​​of the fan speed corresponding to the compressor initial frequency; The stable operating time indicates the time it takes for the system to adjust the outlet air temperature to a stable state after determining the adjustment values ​​for the compressor frequency and fan speed. The second preset threshold group includes several thresholds preset in the inner loop control logic, used to determine the range of the current indoor temperature; The second comparison result characterizes the system's comparison results based on the current indoor temperature and several pre-set thresholds in the inner loop control logic; The third preset threshold group includes a first temperature threshold and a second temperature threshold, which are used to compare with the difference between the current air outlet temperature and the target air outlet temperature to determine the stable operation time. In this embodiment, the first temperature threshold and the second temperature threshold are set to 3 degrees Celsius and 5 degrees Celsius, respectively.

[0028] Please see Figure 2 In some embodiments, step S101 may include, but is not limited to, steps S201 to S204: Step S201: Perform outer loop calculation based on the current outdoor temperature, current operating mode, and first preset threshold group to determine candidate parameter group; Step S202: Perform inner loop calculation based on the current indoor temperature, candidate parameter group and second preset threshold group to determine the initial operating parameters; Step S203: Calculate and determine the adjustment value based on the first difference, the preset tolerance range, the current operating mode, and the initial operating parameters; Step S204: Calculate and determine the stable operation time based on the first difference, the third preset threshold group, and the preset tolerance range, and determine the control parameters based on the stable operation time and adjustments.

[0029] In step S201 of some embodiments, an outer loop control logic and an inner loop control logic are set up to calculate control parameters for controlling and adjusting the air conditioning equipment based on the real-time collected outdoor and indoor temperatures, respectively. In this embodiment, the outer loop control logic is first calculated based on the real-time collected outdoor temperature to determine the initial control parameter set of the air conditioning equipment, including multiple initial operating frequency platforms for the air conditioning compressor under the current outdoor temperature, as well as the initial speed and lower speed limit of the internal fan.

[0030] In step S202 of some embodiments, after determining the initial control parameter set based on the outer loop control logic and the current outdoor temperature, the inner loop control logic is calculated based on the real-time collected indoor temperature, and the optimal initial control parameters are selected from the determined initial control parameter set to perform preliminary control on the compressor and built-in fan of the air conditioning equipment.

[0031] In step S203 of some embodiments, the adjustment of the air conditioning equipment operating parameters is calculated based on the real-time calculated air conditioner outlet temperature difference and the preset error allowable range, so as to make real-time fine adjustments to the air conditioning equipment, and the type of parameter adjustment is determined according to the current operating mode of the air conditioning equipment. For example, in the cooling mode, if the air conditioner outlet temperature is too high, it is necessary to increase the operating frequency of the air conditioner compressor and reduce the speed of the built-in fan to reduce the outlet temperature; while in the heating mode, if the air conditioner outlet temperature is too high, the operating frequency of the air conditioner compressor is reduced and the speed of the built-in fan is increased.

[0032] In step S204 of some embodiments, the operating parameters of the air conditioning equipment are adjusted based on the real-time collected outlet air temperature, indoor temperature, and outdoor temperature to bring the outlet air temperature to the set value. However, at this time, there is still a large difference between the indoor temperature and the outlet air temperature. Therefore, it is necessary to continuously adjust the outlet air temperature for a period of time to make the outlet air temperature stable, thereby adjusting the indoor temperature to reach the set target temperature. In this embodiment, the corresponding stable operating time is determined based on the difference between the real-time collected outlet air temperature and the set target outlet air temperature, as well as the degree of deviation from the allowable error range. The air conditioning control system adjusts the air conditioning equipment according to the determined stable operating time and the real-time calculated adjustment parameters to achieve stable outlet air temperature operation.

[0033] Please see Figure 3 In some embodiments, step S201 may include, but is not limited to, steps S301 to S203: Step S301: Compare the current outdoor temperature with the first preset threshold group, determine the first comparison result, and analyze the current operating mode to determine the mode type; Step S302: If the mode type is cooling mode, match the first comparison result with the first parameter group to determine the candidate parameter group; Step S303: If the mode type is heating mode, match the first comparison result with the second parameter group to determine the candidate parameter group.

[0034] In step S301 of some embodiments, the air conditioning control device sets several different initial operating parameters according to different air conditioning operating modes; each set of initial operating parameters is set according to the temperature range of the current outdoor temperature; the air conditioning control device compares the real-time collected outdoor temperature with several set thresholds to determine the temperature range corresponding to the current outdoor temperature; at the same time, it obtains the current air conditioning device operating mode type so as to select the initial operating parameter group under the corresponding mode in the future.

[0035] In step S302 of some embodiments, if the air conditioning device is currently operating in cooling mode, the control device selects multiple sets of initial operating parameters corresponding to the cooling mode; based on the temperature range of the current outdoor temperature, the corresponding initial operating parameter is selected from the multiple sets of initial operating parameters as the optimal initial operating parameter; for example, by comparing and determining that the current outdoor temperature is greater than the maximum value among several set thresholds, it can be determined that the current outdoor environment is hot and the set target air outlet temperature is low. Therefore, the corresponding initial operating parameters are set to a higher state, such as setting the compressor frequency to a higher range and setting the speed of the built-in fan to a higher level, so as to improve the adjustment rate of the air outlet temperature and thus improve the adjustment efficiency.

[0036] In step S303 of some embodiments, if the air conditioning device is currently operating in heating mode, the control device selects multiple sets of initial operating parameters corresponding to the heating mode, and then selects the optimal operating parameters as candidate parameter groups from the multiple sets of initial operating parameters corresponding to the heating mode based on the temperature range of the current outdoor temperature determined by comparison.

[0037] Please see Figure 4 In some embodiments, step S202 may include, but is not limited to, steps S401 to S402: Step S401: Compare the current indoor temperature with the second preset threshold group to determine the second comparison result; Step S402: Match the second comparison result with the candidate parameter group to determine the initial operating parameters; wherein, the initial operating parameters include the compressor's initial operating frequency, the indoor unit's initial speed, and the lower limit of the speed.

[0038] In step S401 of some embodiments, after determining the candidate parameter group through the outer loop control logic, calculations are performed based on the current indoor temperature and the determined candidate parameter group. The optimal operating parameters from the candidate parameter group are used to adjust and control the air conditioning equipment with higher precision. In this embodiment, the real-time indoor temperature is compared with several sets of set indoor temperature thresholds to determine the temperature range of the current indoor temperature, so as to select initial operating parameters from the candidate parameter group to control the air conditioning equipment.

[0039] In step S402 of some embodiments, the control device selects the corresponding initial operating parameters from the candidate parameter group according to the temperature range and controls the air outlet temperature of the air conditioning equipment. In this embodiment, the candidate parameter group includes three operating frequency platforms of the air conditioning compressor, the initial speed of the built-in fan, and the lower limit of the speed. According to the temperature range of the current indoor temperature, the optimal operating frequency is selected from the three operating frequency platforms as the initial operating frequency, and the initial speed and corresponding lower limit of the fan are selected.

[0040] Please see Figure 5 In some embodiments, step S203 may include, but is not limited to, steps S501 to S503: Step S501: Analyze the current operating mode, determine the mode type, and compare the first difference with the preset tolerance range; Step S502: If the mode type is cooling and the first difference is greater than the upper limit of the preset tolerance range, or if the mode type is heating and the first difference is less than the lower limit of the preset tolerance range, calculate and determine the adjustment value based on the first parameter and the initial operating parameters. Step S503: If the mode type is cooling and the first difference is less than the lower limit of the preset tolerance range, or if the mode type is heating and the first difference is greater than the upper limit of the preset tolerance range, the adjustment value is determined by calculation based on the second parameter and the initial operating parameters.

[0041] In step S501 of some embodiments, after determining the initial operating parameters of the compressor and built-in fan in the air conditioner, the parameter adjustment value is determined based on the deviation range between the current outlet air temperature and the set target outlet air temperature and the allowable error range. Based on the determined initial operating parameters, the control device makes a more precise adjustment to the compressor frequency and fan speed according to the parameter adjustment value, so that the air conditioner outlet air temperature is close to the set target outlet air temperature, or the difference falls within the allowable error range.

[0042] In step S502 of some embodiments, the control device determines the adjustment method for the compressor frequency and fan speed based on the current operating mode of the air conditioner and the deviation of the current outlet air temperature difference from the allowable error range, such as increasing the compressor frequency and decreasing the fan speed. Then, based on the set adjustment parameters and the determined initial operating parameters, the control device calculates the adjustment value to adjust the air conditioner outlet air temperature. In this embodiment, the control device determines that the outlet air temperature difference is greater than the upper limit of the allowable error range in the cooling mode, i.e., the outlet air temperature is too high in the cooling mode; or the control device determines that the outlet air temperature difference is less than the lower limit of the allowable error range in the heating mode, i.e., the outlet air temperature is too low in the heating mode. The control device needs to calculate the adjustment value to adjust the outlet air temperature using the following formula: , in, This is the compressor frequency adjustment value. This is the fan speed adjustment value. This is the initial frequency of the compressor. This is the initial speed of the fan. To adjust the time, For frequency adjustment rate, This refers to the speed adjustment rate.

[0043] In step S503 of some embodiments, the control device determines that the air outlet temperature difference of the air conditioner is less than the lower limit of the allowable error range in cooling mode, or greater than the upper limit of the allowable error range in heating mode, i.e., the air outlet temperature is too low in cooling mode or too high in heating mode; the control device calculates an adjustment value according to the aforementioned calculation formula and adjusts the air outlet temperature of the air conditioner.

[0044] Please see Figure 6 In some embodiments, step S204 may include, but is not limited to, steps S601 to S605: Step S601: Analyze the preset tolerance range, determine the tolerance value, and compare the absolute value of the first difference and the tolerance value with the third preset threshold group; wherein, the third preset threshold group includes the first temperature threshold and the second temperature threshold. Step S602: If the absolute value of the first difference is less than the allowable tolerance value, maintain the current state; Step S603: If the absolute value of the first difference is greater than or equal to the allowable value, and the absolute value of the first difference is less than the first temperature threshold, the first preset time is determined as the stable operation time. Step S604: If the absolute value of the first difference is greater than or equal to the first temperature threshold and the absolute value of the first difference is less than the second temperature threshold, the second preset duration is determined as the stable operating duration. Step S605: If the absolute value of the first difference is greater than or equal to the second threshold, the third preset duration is determined as the stable running duration; wherein, the first preset duration is greater than the second preset duration, and the second preset duration is greater than the third preset duration.

[0045] In step S601 of some embodiments, the allowable error range is determined based on the target air outlet temperature and the allowable error value, and the allowable error value is determined by analyzing the allowable error range; the control device determines the stable operation time based on the degree to which the air outlet temperature difference deviates from the allowable error range, so as to correct and adjust the air outlet temperature of the air conditioning equipment; in this embodiment, multiple temperature thresholds are set, the multiple temperature thresholds increase sequentially, and the multiple temperature thresholds are all greater than the allowable error value, so as to improve the accuracy of judging the degree to which the air outlet temperature difference deviates from the allowable error range, thereby improving the adjustment accuracy of the air outlet temperature of the air conditioning equipment.

[0046] In step S602 of some embodiments, the control device compares the outlet air temperature difference with the error allowable value and sets multiple temperature thresholds, determines the comparison result, and then determines the corresponding stable operating time to adjust the air conditioning equipment. In this embodiment, if the outlet air temperature difference is less than the error allowable value, it means that the outlet air temperature difference falls within the error allowable range. At this time, the outlet air temperature of the air conditioning equipment meets the user's comfort requirements, and the control device maintains the current state of operation.

[0047] In step S603 of some embodiments, the control device determines by comparison that the outlet air temperature difference is greater than the allowable error value, but less than the smallest first threshold among multiple temperature thresholds. The control device determines that the current outlet air temperature of the air conditioning device falls outside the allowable error range, but the deviation is small. Therefore, the set first preset time is used as the stable operation time. The control device adjusts the outlet air temperature according to the stable operation time and the calculated initial operation parameters and adjustment parameters.

[0048] In step S604 of some embodiments, if the control device determines by comparison that the outlet air temperature difference is greater than the first threshold among multiple temperature thresholds but less than the second threshold, the control device determines that the outlet air temperature of the air conditioning unit falls outside the error allowable range and the deviation is large; therefore, the control device uses the second preset duration of a moderate duration as the stable operating duration and adjusts the outlet air temperature of the air conditioning unit through the control device.

[0049] In step S605 of some embodiments, if the control device determines by comparison that the outlet air temperature difference is greater than the second threshold among multiple temperature thresholds, but less than the largest third threshold, the control device determines that the deviation of the outlet air temperature of the air conditioning device is large. At this time, the adjustment parameter calculated by the control device based on outdoor temperature, indoor temperature, etc. is large, that is, the adjustment range of the outlet air temperature is large. Therefore, the control device uses the shortest third preset duration as the stable operation duration and adjusts the outlet air temperature of the air conditioning device through the control device.

[0050] Please see Figure 7 In some embodiments, the air conditioning constant temperature air supply control method provided in this application may also include, but is not limited to, steps S701 to S703: Step S701: Obtain the current operating parameters and the current outlet air temperature, and determine the target limit value based on the initial operating parameters and control parameters; Step S702: Compare the current operating parameters with the target limit value, and compare the current air outlet temperature with the preset target air outlet temperature; Step S703: If the current operating parameters are equal to the target limit value and the current air outlet temperature is not equal to the preset target air outlet temperature, display the current air outlet temperature and generate fault information.

[0051] In step S701 of some embodiments, the control device adjusts the air outlet temperature of the air conditioning unit according to the calculated adjustment parameters and the stable operation time. At the same time, the control device collects the current air outlet temperature and the current operating parameters of the air conditioning unit in real time through the set data acquisition devices such as sensors, such as the compressor operating frequency and the fan speed. The control device determines the target limit value of the air conditioning unit based on the real-time collected operating parameters and the set control parameters, such as the upper limit of the compressor operating frequency and the lower limit of the fan speed.

[0052] In step S702 of some embodiments, the control device compares the real-time collected operating parameters with the calculated target limit value and calculates the current air outlet temperature difference to determine whether to adjust the air conditioner air outlet temperature.

[0053] In step S703 of some embodiments, the control device determines by comparison that the current outlet air temperature difference is still outside the error allowable range, but at this time the operating parameters of the air conditioning equipment have reached the target limit value. At this time, the control device stops adjusting the air conditioning equipment according to the calculated adjustment parameters, displays the real-time collected outlet air temperature through the front-end display device, and generates fault information to send to the operation and maintenance personnel for processing. In this embodiment, a fault notification will be issued when an ultra-low outlet air temperature is set at ultra-high temperature and an ultra-high outlet air temperature is set at ultra-low temperature.

[0054] The following is a detailed description and explanation of the solutions in the embodiments of the present invention, using specific application examples: Please see Figure 8 , Figure 8 This is a flowchart illustrating a control method for constant temperature air supply in an air conditioner, as provided in an embodiment of this application, applied in a specific embodiment. In this embodiment, the user sets a target outlet air temperature through a controller, and the air conditioning equipment detects the actual outlet air temperature in real time through a sensor. The difference between the actual outlet air temperature and the target outlet air temperature is calculated, and it is determined whether it is within the allowable error range. If the difference is within the allowable error range, the air conditioning equipment maintains its current operation to achieve constant temperature air supply. If the difference is outside the allowable error range, the initial operating parameters of the air conditioning equipment are determined using outer-loop logic and inner-loop logic. The outer-loop logic and inner-loop logic are set with operating parameter ranges as shown in the table below. Table 1

[0055] Table 1 (continued)

[0056] Table 2

[0057] First, the current outdoor temperature is detected and compared with the set outer loop range to determine the target range. Based on the target range, the initial operating frequency of the compressor and the initial speed of the fan in the air conditioning equipment are determined. Then, the current indoor temperature is detected and compared with the set inner loop range to determine the initial parameters that meet the requirements for adjustment. Simultaneously, the external fan and electronic expansion valve operate under normal control. The control method provided in this embodiment does not control the external fan and electronic expansion valve. Next, based on the current operating mode of the air conditioning equipment and the outlet air temperature difference, the adjustment method and magnitude of the compressor frequency and fan speed are determined. For example, in cooling mode, if the outlet air temperature difference exceeds the upper limit of the error range, the air conditioning equipment increases the compressor frequency and decreases the fan speed to lower the outlet air temperature. Finally, based on the absolute value of the outlet air temperature, the allowable error value, and the set... The system compares the temperature thresholds to determine the stabilization time, such as 3℃ and 5℃. If the absolute value of the outlet air temperature falls between the allowable error value and 3℃, the stabilization time is set to 8 minutes; if the absolute value of the outlet air temperature falls between 3℃ and 5℃, the stabilization time is set to 5 minutes. The air conditioning unit adjusts the outlet air temperature according to the determined stabilization time and adjustment parameters, and detects the outlet air temperature difference in real time to determine whether it falls within the preset error range. It also checks whether the adjusted outlet air temperature exceeds the tolerance. If no reverse tolerance occurs, the air conditioning unit continues to adjust according to the current adjustment parameters and updates the stabilization time to adjust the outlet air temperature. If a reverse tolerance occurs, the adjustment parameters are switched. If the real-time detected outlet air temperature difference falls within the preset error range after adjustment, the air conditioning unit maintains its current operation to achieve constant temperature air supply. Simultaneously, after detecting that all equipment has reached its limit, the air conditioning unit displays the current outlet air temperature and sends a fault message.

[0058] The embodiments of this application include at least the following beneficial effects: This application provides a control method, device, electronic device, storage medium, and program product for constant temperature air supply in an air conditioner. This solution determines whether the difference between the current air outlet temperature and the set target air outlet temperature is within a preset tolerance range. If the difference is within the preset tolerance range, the air conditioner is controlled to maintain its current operating state. If the difference is outside the preset tolerance range, the current indoor and outdoor temperatures are collected and used for temperature control to determine the control parameters for controlling the air conditioner. The air outlet temperature of the air conditioner is adjusted according to the control parameters to achieve the set target air outlet temperature. By directly controlling the air outlet temperature and dynamically controlling it based on the difference between the air outlet temperature and the set target value, the error caused by indirect control is reduced, and the control accuracy is improved. Furthermore, by combining the indoor and outdoor temperatures to control the air outlet temperature of the air conditioner, the control accuracy is further improved.
