Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning system and its control method, as well as a computer-readable storage medium. Background Technology

[0002] Residential water chillers supply hot or cold water to indoor units via an outdoor unit to achieve the corresponding heating or cooling effect. In related technologies, users can only adjust the temperature control of the indoor unit, and only have control over the outdoor unit's on / off operation. The outdoor unit's water supply temperature and operating mode need to be set separately via a manual control panel, which is inconvenient to use. For most operating conditions, the limited water temperature control of the outdoor unit leads to high energy consumption. Summary of the Invention

[0003] The present invention provides an air conditioning system and its control method, and a computer-readable storage medium to solve at least one of the above-mentioned technical problems.

[0004] An embodiment of the present invention provides a control method for an air conditioning system, comprising:

[0005] Obtain a corrected temperature, which is determined based on the temperature control mode and set temperature of at least one indoor unit, as well as the outdoor temperature and the indoor temperature;

[0006] The outdoor unit is controlled to supply water to the at least one indoor unit according to the corrected temperature.

[0007] The above control method determines the indoor operating conditions by using the indoor temperature, the indoor unit's temperature adjustment mode, and the set temperature, and determines the outdoor operating conditions by using the outdoor temperature. This allows the outdoor unit to determine the water supply temperature based on both indoor and outdoor operating conditions, making the water supply temperature more in line with actual needs. Compared to supplying water at a fixed temperature, this method helps reduce energy consumption.

[0008] The control method includes:

[0009] Obtain a temperature control reference value and a temperature control coefficient. The temperature control coefficient includes a first coefficient, a second coefficient, and a third coefficient. The temperature control reference value is determined according to the temperature control mode of the indoor unit. The first coefficient is determined according to the outdoor temperature. The second coefficient is determined according to the indoor temperature. The third coefficient is determined according to the indoor temperature and the set temperature.

[0010] The correction temperature is determined based on the aforementioned temperature control reference value and temperature control coefficient. This allows for the reasonable adjustment of the water supply temperature of the outdoor unit.

[0011] Determining the corrected temperature based on the temperature control reference value and the temperature control coefficient includes:

[0012] The temperature regulation coefficient is used as a weight in the calculation to determine the corrected temperature based on the temperature regulation reference value. This provides a specific solution for determining the required water supply temperature for the outdoor unit.

[0013] The control method includes:

[0014] The first coefficient is determined based on the range of the outdoor temperature; and / or

[0015] The second coefficient is determined based on the range of the indoor temperature; and / or

[0016] The third coefficient is determined based on the range of the difference between the indoor temperature and the set temperature. This facilitates the rapid determination of the appropriate coefficient according to the actual situation.

[0017] The control method includes:

[0018] If the obtained corrected temperature is determined to be less than the cooling limit temperature, the corrected temperature is adjusted to the cooling limit temperature; and / or

[0019] If the obtained corrected temperature is determined to be greater than the heating limit temperature, the corrected temperature is adjusted to the heating limit temperature. This helps to ensure the operational stability of the air conditioning system.

[0020] The control method includes:

[0021] When the number of indoor unit devices is at least two, a quasi-corrected temperature is obtained for each of the at least two indoor unit devices, and each indoor unit device has a corresponding set temperature and an indoor temperature;

[0022] The correction temperature is determined based on the maximum and minimum values ​​of at least two quasi-correction temperatures and the corresponding temperature control mode of the indoor unit. This facilitates multi-unit control of the air conditioning system.

[0023] The control method includes:

[0024] If the obtained corrected temperature is determined to be greater than the cooling set temperature, the corrected temperature is adjusted according to the cooling set temperature, which is the minimum of at least two set temperatures; and / or

[0025] If the corrected temperature is determined to be lower than the heating set temperature, the corrected temperature is adjusted according to the heating set temperature, which is the maximum value of at least two set temperatures. This ensures that different indoor unit devices can achieve the corresponding temperature control effect.

[0026] The control method includes:

[0027] The correction temperature is determined according to a preset cycle. This helps to ensure sufficient temperature control effect.

[0028] The control method includes:

[0029] If the temperature control modes of the first indoor unit and the second indoor unit are inconsistent, the temperature control mode of the first indoor unit is acquired, and the temperature control request of the second indoor unit is not responded to; the first indoor unit turns on before the second indoor unit.

[0030] The temperature control mode with the highest proportion of indoor unit devices is selected. This ensures that high-priority temperature control needs can be met.

[0031] The control method includes:

[0032] When the indoor temperature reaches the set temperature, the water supply to the corresponding indoor unit is stopped. This helps reduce energy consumption.

[0034] At least one indoor unit;

[0035] At least one wired controller, each of the wired controllers being communicatively connected to a corresponding indoor unit device, the wired controllers being used to determine a correction temperature based on the temperature adjustment mode and set temperature of the at least one indoor unit device, as well as the outdoor temperature and the indoor temperature; and

[0039] The above control method determines the indoor operating conditions by using the indoor temperature, the indoor unit's temperature adjustment mode, and the set temperature, and determines the outdoor operating conditions by using the outdoor temperature. This allows the outdoor unit to determine the water supply temperature based on both indoor and outdoor operating conditions, making the water supply temperature more in line with actual needs. Compared to supplying water at a fixed temperature, this method helps reduce energy consumption.

[0053] In the description of this invention, examples of some disclosed embodiments are illustrated accordingly in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention.

[0054] In the description of this invention, many different embodiments or examples are disclosed to implement different structures of the invention. To simplify the disclosure of this invention, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit the invention.

[0055] Furthermore, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0056] Please refer to Figure 1 A control method for an air conditioning system 10 according to an embodiment of the present invention includes:

[0057] 01: Obtain the corrected temperature, which is determined based on the temperature control mode and set temperature of at least one indoor unit 11, as well as the outdoor temperature and indoor temperature;

[0058] 02: Control the outdoor unit 12 to supply water to at least one indoor unit 11 according to the corrected temperature.

[0059] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The air conditioning system 10 includes at least one indoor unit 11, at least one wired controller 13, and an outdoor unit 12. Each wired controller 13 is communicatively connected to a corresponding indoor unit 11. The wired controller 13 is used to determine a correction temperature based on the temperature control mode and set temperature of the at least one indoor unit 11, as well as the outdoor temperature and the indoor temperature. The outdoor unit 12 is communicatively connected to at least one wired controller 13, and is used to: acquire the correction temperature; and supply water to the indoor unit 11 according to the correction temperature.

[0060] The above-mentioned control method and air conditioning system 10 determine the indoor operating conditions by the indoor temperature, the temperature adjustment mode and the set temperature of the indoor unit equipment 11, and determine the outdoor operating conditions by the outdoor temperature. This allows the outdoor unit equipment 12 to determine the water supply temperature based on the indoor and outdoor operating conditions, making the water supply temperature more in line with actual needs. Compared with the method of supplying water at a fixed water temperature, this helps to reduce energy consumption.

[0061] The corrected temperature is the result of considering factors such as the temperature control mode of the indoor unit 11, the user's desired temperature, and the indoor and outdoor temperature environments. The corrected temperature reflects the current application scenario, ensuring that the water supply has a reasonable temperature that best meets the user's expectations while also taking into account the energy consumption of the air conditioning system 10.

[0062] The temperature control mode can include a cooling mode and a heating mode. When the indoor unit 11 is in cooling mode, the set temperature for the indoor unit 11 will be a value lower than the indoor temperature, and the outdoor unit 12 will supply the indoor unit 11 with cooler water to meet its cooling needs. When the indoor unit 11 is in heating mode, the set temperature for the indoor unit 11 will be a value higher than the indoor temperature, and the outdoor unit 12 will supply the indoor unit 11 with warmer water to meet its heating needs.

[0063] Users can select the temperature control mode of the indoor unit 11 through the wired controller 13.

[0064] The set temperature is a temperature value that the user expects the room to reach. The user can set the set temperature through the wired controller 13.

[0065] The outdoor temperature is the temperature relative to the external environment of the room where the indoor unit 11 is installed, or the temperature outside the room. The outdoor unit 12 can be installed outdoors, thus the temperature of the area where the outdoor unit 12 is located can be determined as the outdoor temperature. The outdoor temperature can be obtained through a temperature sensor installed outdoors. The outdoor temperature sensor can be located on the exterior wall of the room relative to the room, or it can be located on the outdoor unit 12. The outdoor temperature can also be obtained via network connection.

[0066] Indoor temperature refers to the temperature of the interior environment of the room where the indoor unit 11 is installed, or the temperature inside the room. Indoor temperature can be obtained through a temperature sensor installed indoors. The temperature sensor can be located on an interior wall of the room or on the indoor unit 11. Indoor temperature can also be obtained via network connection.

[0067] The air conditioning system 10 can be a residential water system. For a residential water system, the outdoor unit 12 consumes energy to produce chilled or hot water and delivers it to the indoor unit 11 for water supply, thereby meeting the cooling or heating needs of the indoor unit 11.

[0068] The wired controller 13 may include an operation panel (not shown), which may be equipped with operation controls (not shown). Users can operate some of the operation controls to set the set temperature of the corresponding indoor unit 11. Alternatively, it can be understood that users set the desired indoor temperature through the wired controller 13.

[0069] Users can also operate other control buttons to realize different functions of the wired controller 13. The different functions of the wired controller 13 can include setting the working mode of the indoor unit 11, controlling the indoor unit 11 to turn on or off, and adjusting the air outlet speed of the indoor unit 11.

[0070] It is understandable that, compared to the temperature control scheme using a thermostat in related technologies, the embodiment of the present invention, by setting a wired controller 13, can control the water supply temperature of the outdoor unit 12 according to indoor needs, without the need to separately set the water temperature and temperature control mode, which is beneficial to improving the convenience of use. The outdoor unit 12 can supply water at a specific temperature, which can avoid the problem of increased energy consumption caused by providing water at a single temperature that is too hot or too cold to meet the temperature control requirements as much as possible. It can also prevent the compressor of the outdoor unit 12 from running at a high load for a long time, thereby improving the unit's energy efficiency.

[0071] exist Figure 2 In this system, the indoor unit 11 may include an air conditioning unit or a floor heating unit. Both the indoor unit 11 and the outdoor unit 12 can use water as a refrigerant to achieve a cooling or heating effect.

[0072] exist Figure 2 In this system, the air conditioning system 10 may include a water pump 14. The water pump 14 is installed on the water supply pipe between the indoor unit 11 and the outdoor unit 12. When the indoor unit 11 is turned on, the corresponding wired controller 13 can send a notification to the outdoor unit 12 that the indoor unit 11 has been turned on, thereby turning on the outdoor unit 12. The air conditioning system 10 will then turn on the water pump 14 accordingly, enabling the outdoor unit 12 to supply water to the indoor unit 11.

[0073] exist Figure 2 In the diagram, the water supply pipe between the indoor unit 11 and the outdoor unit 12 is represented by a solid line, and the communication channel between the wired controller 13 and the outdoor unit 12 is represented by a dashed line. The communication channel can be represented as wired communication or wireless communication.

[0074] Control methods may include:

[0075] Obtain the temperature control reference value and temperature control coefficient. The temperature control coefficient includes a first coefficient, a second coefficient, and a third coefficient. The temperature control reference value is determined according to the temperature control mode of the indoor unit device 11. The first coefficient is determined according to the outdoor temperature. The second coefficient is determined according to the indoor temperature. The third coefficient is determined according to the indoor temperature and the set temperature.

[0076] The correction temperature is determined based on the temperature control reference value and the temperature control coefficient.

[0077] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The wired controller 13 is used to: obtain the temperature adjustment reference value and the temperature adjustment coefficient, the temperature adjustment coefficient including a first coefficient, a second coefficient and a third coefficient, the temperature adjustment reference value is determined according to the temperature adjustment mode of the indoor unit device 11, the first coefficient is determined according to the outdoor temperature, the second coefficient is determined according to the indoor temperature, and the third coefficient is determined according to the indoor temperature and the set temperature; and determine the correction temperature according to the temperature adjustment reference value and the temperature adjustment coefficient.

[0078] In this way, the water supply temperature of the outdoor unit 12 can be reasonably adjusted.

[0079] The temperature control reference value is determined based on the temperature control mode of the indoor unit 11, so that the outdoor unit 12 can determine whether to heat at a higher temperature or cool at a lower temperature.

[0080] The first coefficient reflects the outdoor temperature, the second coefficient reflects the indoor temperature, and the third coefficient reflects the change in indoor temperature during the process of the indoor unit 11 adjusting the temperature according to the set temperature. The third coefficient can be determined by the difference between the indoor temperature and the set temperature.

[0081] Determining the correction temperature based on the temperature control reference value and temperature control coefficient can include:

[0082] The temperature adjustment coefficient is used as the weight of the temperature adjustment reference value for calculation to determine the correction temperature.

[0083] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The wired controller 13 is used to: calculate and process the temperature control coefficient as the weight of the temperature control reference value to determine the correction temperature.

[0084] In this way, a specific solution can be provided to determine the water supply temperature that the outdoor unit 12 needs to reach.

[0085] When the indoor unit 11 is set to cooling mode, the corrected temperature can be determined using the following formula:

[0086] T = m * a * b * c;

[0087] Where T is the corrected temperature, m is the temperature control reference value in cooling mode, a is the first coefficient in cooling mode, b is the second coefficient in cooling mode, and c is the third coefficient in cooling mode.

[0088] When the indoor unit 11 is set to heating mode, the corrected temperature can be determined using the following formula:

[0089] T = n * d * e * f;

[0090] Where T is the corrected temperature, n is the temperature control reference value in heating mode, d is the first coefficient in heating mode, e is the second coefficient in heating mode, and f is the third coefficient in heating mode.

[0091] The temperature control reference value can be configured to different values ​​depending on the temperature control mode. Specifically, in cooling mode, the temperature control reference value can be 7℃, or in other words, the outdoor unit 12 will be adjusted based on 7℃; in heating mode, the temperature control reference value can be 25℃, or in other words, the outdoor unit 12 will be adjusted based on 25℃.

[0092] In practice, the default water supply temperature for residential water systems is 7°C when cooling and 25°C when heating, which matches the default temperature control configuration of residential water systems.

[0093] For the same temperature control mode, the temperature control reference value can be selected within the corresponding value range.

[0094] In addition, it is understood that, for those skilled in the art, other calculation methods (such as adding or subtracting to supplement the temperature correction amount, or substituting the corresponding coefficients into other pre-designed mathematical function models to calculate the result) can be used to obtain the corrected temperature, thereby making it convenient to quickly obtain the result and adjust the target water supply temperature of the outdoor unit 12 according to the actual situation.

[0095] Control methods may include:

[0096] Determine the first coefficient based on the range of outdoor temperature; and / or

[0097] The second coefficient is determined based on the range of indoor temperature; and / or

[0098] The third coefficient is determined based on the range of the difference between the indoor temperature and the set temperature.

[0099] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The wired controller 13 is used to: determine a first coefficient based on the range of outdoor temperature; and / or determine a second coefficient based on the range of indoor temperature; and / or determine a third coefficient based on the range of the difference between indoor temperature and set temperature.

[0100] This allows for the rapid determination of the appropriate coefficients based on the actual situation.

[0101] The first coefficient in cooling mode can be determined using Table 1:

[0102] Outdoor temperature (°C) ≤35 35＜≤40 ＞40 a 1 1.2 1.4

[0103] Table 1

[0104] As shown in Table 1, when the indoor unit 11 is in cooling mode, the corresponding first coefficient will vary depending on the range of outdoor temperature. As the outdoor temperature increases, the first coefficient tends to increase sequentially; this ensures sufficient cooling effect while preventing excessive temperature difference between the refrigerant in the outdoor unit 12 and the outdoor temperature, which could lead to malfunction of the outdoor unit 12.

[0105] The second coefficient in cooling mode can be determined using Table 2:

[0106] Indoor temperature (°C) ≤20 20＜≤25 25＜≤30 ＞30 b 1.8 1.4 1.2 1

[0107] Table 2

[0108] As shown in Table 2, when the indoor unit 11 is in cooling mode, the corresponding second coefficient will vary depending on the indoor temperature range. The second coefficient tends to decrease as the indoor temperature increases.

[0109] The third coefficient in cooling mode can be determined using Table 3:

[0110] Indoor temperature - Set temperature (°C) ≤0 0＜≤2 2＜≤4 ＞4 c 3 1.2 1.1 1

[0111] Table 3

[0112] As shown in Table 3, when the indoor unit 11 is in cooling mode, the corresponding third coefficient will vary depending on the range of the difference between the indoor temperature and the set temperature. As the difference between the indoor temperature and the set temperature increases, the third coefficient tends to decrease sequentially.

[0113] The first coefficient in heating mode can be determined using Table 4:

[0114] Outdoor temperature (°C) ≤-10 -10＜≤0 ＞0 d 1.5 1.4 1.2

[0115] Table 4

[0116] As shown in Table 4, when the indoor unit 11 is in heating mode, the corresponding first coefficient will vary depending on the outdoor temperature range. As the outdoor temperature increases, the first coefficient tends to decrease sequentially.

[0117] The second coefficient in heating mode can be determined using Table 5:

[0118] Indoor temperature (°C) ≤10 10＜≤15 15＜≤20 ＞20 e 1.4 1.3 1.2 1

[0119] Table 5

[0120] As shown in Table 5, when the indoor unit 11 is in heating mode, the corresponding second coefficient will vary depending on the indoor temperature range. The second coefficient tends to decrease as the indoor temperature increases.

[0121] The third coefficient in heating mode can be determined using Table 6:

[0122] Indoor temperature - Set temperature (°C) ≤0 0＜≤2 2＜≤4 ＞4 f 1 1.2 1.3 1.4

[0123] Table 6

[0124] As shown in Table 6, when the indoor unit 11 is in heating mode, the corresponding third coefficient will vary depending on the range of the difference between the indoor temperature and the set temperature. The third coefficient tends to increase as the difference between the indoor temperature and the set temperature increases.

[0125] Furthermore, the above embodiments are some optional embodiments of the present invention, and the correspondence between different intervals and different coefficients can be obtained through calibration. For other embodiments of the present invention, different intervals and different coefficients can be recalibrated according to different actual situations.

[0126] Furthermore, the first, second, and third coefficients can be calibrated in a manner similar to the above-described implementation method, or they can be determined through real-time calculation in specific circumstances.

[0127] Control methods may include:

[0128] If the obtained corrected temperature is determined to be less than the refrigeration limit temperature, the corrected temperature is adjusted to the refrigeration limit temperature; and / or

[0129] If the obtained corrected temperature is determined to be greater than the heating limit temperature, the corrected temperature is adjusted to the heating limit temperature.

[0130] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2The outdoor unit 12 is used to: adjust the corrected temperature to the cooling limit temperature when the determined corrected temperature is less than the cooling limit temperature; and / or adjust the corrected temperature to the heating limit temperature when the determined corrected temperature is greater than the heating limit temperature.

[0131] This helps ensure the operational stability of the air conditioning system 10.

[0132] Indoor unit 11 may include radiant temperature control equipment. Radiant temperature control equipment achieves indoor temperature regulation through heat conduction. The cooling limit temperature can be the minimum operating temperature of the radiant temperature control equipment. If the obtained corrected temperature is determined to be lower than the cooling limit temperature, it can be determined that there is a possibility that the temperature regulation effect of the radiant temperature control equipment may be affected. Therefore, the corrected temperature is adjusted to the cooling limit temperature to ensure the temperature regulation effect of the radiant temperature control equipment. The cooling limit temperature can be 18℃. Radiant temperature control equipment may include underfloor heating.

[0133] For outdoor unit 12, heating and cooling of water are achieved through refrigerant heat exchange. If the corrected temperature is determined to be higher than the heating limit temperature, then the refrigerant within outdoor unit 12 needs to be at a high temperature for heat exchange with the water. However, refrigerant at high temperatures is often under high pressure, which could cause the heat exchange pipes within outdoor unit 12 to be under high pressure, posing a risk of loss of control and safety hazards. Therefore, the corrected temperature is adjusted to the heating limit temperature to ensure that the refrigerant within outdoor unit 12 remains within a controllable range. The heating limit temperature can be 50℃.

[0134] Based on the above, setting the cooling limit temperature can ensure the cooling effect of the indoor unit 11, and setting the heating limit temperature can prevent runaway, thereby improving the operational stability of the air conditioning system 10.

[0135] Control methods may include:

[0136] When the number of indoor unit devices 11 is at least two, a quasi-corrected temperature corresponding to each of the at least two indoor unit devices 11 is obtained, and each indoor unit device 11 has a corresponding set temperature and an indoor temperature;

[0137] The correction temperature is determined based on the maximum and minimum values ​​of at least two quasi-correction temperatures and the corresponding temperature control mode of the indoor unit 11.

[0138] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2The outdoor unit 12 is used to: when there are at least two indoor units 11, obtain a quasi-corrected temperature corresponding to each of the at least two indoor units 11, each indoor unit 11 having a corresponding set temperature and an indoor temperature; and determine the corrected temperature based on the maximum and minimum values ​​of the at least two quasi-corrected temperatures and the corresponding temperature adjustment mode of the indoor unit 11.

[0139] This facilitates the multi-unit control of the air conditioning system 10.

[0140] It is understood that each indoor unit 11 can be communicatively connected to a corresponding wired controller 13. The wired controller 13 can determine the corrected temperature of the corresponding indoor unit 11 and use it as the quasi-corrected temperature. The quasi-corrected temperatures of each indoor unit 11 can be the same or different.

[0141] For each quasi-corrected temperature, the temperature adjustment mode is the temperature adjustment mode of the corresponding indoor unit 11, the set temperature is the set temperature of the corresponding indoor unit 11, and the indoor temperature is the temperature in the room where the corresponding indoor unit 11 is located.

[0142] The wired controller 13 can send the quasi-corrected temperature to the outdoor unit 12. Upon receiving different quasi-corrected temperatures from the wired controller 13, the outdoor unit 12 can determine, based on the temperature control mode of the indoor unit 11, whether to select the minimum or maximum value of at least two quasi-corrected temperatures as the corrected temperature. If the indoor unit 11 is in cooling mode, the minimum value of the at least two quasi-corrected temperatures will be used as the corrected temperature. If the indoor unit 11 is in heating mode, the maximum value of the at least two quasi-corrected temperatures will be used as the corrected temperature.

[0143] It is understandable that when the indoor unit 11 is in cooling mode, selecting the minimum of at least two quasi-correction temperatures as the correction temperature ensures that all indoor units 11 can meet the desired cooling requirements. When the indoor unit 11 is in heating mode, selecting the maximum of at least two quasi-correction temperatures as the correction temperature ensures that all indoor units 11 can meet the desired heating requirements.

[0144] In addition, when some indoor units 11 have different temperature control modes, the outdoor unit 12 can first meet the temperature control needs of the indoor units 11 that are turned on earlier, and then meet the temperature control needs of the indoor units 11 that are turned on later. Alternatively, it can first meet the temperature control needs of the indoor units 11 with the largest number of indoor units 11, and then meet the temperature control needs of the indoor units 11 with the smaller number of indoor units 11.

[0145] Control methods may include:

[0146] If the determined corrected temperature is greater than the cooling set temperature, the corrected temperature is adjusted based on the cooling set temperature, which is the minimum of at least two set temperatures; and / or

[0147] If the determined correction temperature is less than the heating set temperature, the correction temperature is adjusted according to the heating set temperature, which is the maximum of at least two set temperatures.

[0148] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The outdoor unit 12 is used to: adjust the correction temperature according to the cooling set temperature when the determined correction temperature is greater than the cooling set temperature, wherein the cooling set temperature is the minimum of at least two set temperatures; and / or adjust the correction temperature according to the heating set temperature when the determined correction temperature is less than the heating set temperature, wherein the heating set temperature is the maximum of at least two set temperatures.

[0149] In this way, different indoor unit devices 11 can achieve the corresponding temperature regulation effect.

[0150] When there are at least two indoor unit devices 11, the set temperature of each indoor unit device 11 may be the same or different. If the corrected temperature obtained from the quasi-corrected temperature is greater than the cooling set temperature, it can be determined that the cooling temperature of some indoor unit devices 11 cannot reach the corresponding set temperature. Therefore, the corrected temperature will be adjusted according to the cooling set temperature so that all indoor unit devices 11 that need cooling can achieve the desired cooling effect. If the corrected temperature obtained from the quasi-corrected temperature is less than the heating set temperature, it can be determined that the heating temperature of some indoor unit devices 11 cannot reach the corresponding set temperature. Therefore, the corrected temperature will be adjusted according to the heating set temperature so that all indoor unit devices 11 that need heating can achieve the desired heating effect.

[0151] When at least two indoor units 11 are in cooling mode, the correction temperature can be adjusted based on the cooling set temperature and a first correction value. The first correction value can be -2℃, or, in other words, the result of subtracting 2℃ from the calculated cooling set temperature can be used as the adjusted correction temperature. The first correction value can also be selected within a corresponding range.

[0152] When at least two indoor units 11 are in heating mode, the correction temperature can be adjusted based on the heating set temperature and a second correction value. The second correction value can be +2℃, or in other words, the result of adding 2℃ to the calculated heating set temperature can be used as the adjusted correction temperature. The second correction value can also be selected within a corresponding range.

[0153] Control methods may include:

[0154] The correction temperature is determined according to the preset cycle.

[0155] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The wired controller 13 is used to determine the correction temperature according to a preset cycle.

[0156] This helps to ensure sufficient temperature control.

[0157] It is understandable that when actual conditions change, such as when the user sets a new set temperature, the indoor temperature changes, the outdoor temperature changes, or some indoor units 11 no longer require temperature adjustment, the corresponding correction temperature also needs to be adjusted accordingly. Continuously updating the correction temperature according to a preset cycle ensures timely adjustment, allowing the outdoor unit 12 to adjust its water supply temperature accordingly. This prevents the outdoor unit 12 from supplying water at an outdated correction temperature, which could lead to insufficient water temperature to meet the desired temperature control requirements (e.g., too high a supply temperature for cooling, too low a supply temperature for heating) or excessive energy consumption, thus ensuring adequate temperature control. The preset cycle can be 120 seconds.

[0158] Control methods may include:

[0159] If the temperature control mode of the first indoor unit 11 is inconsistent with the temperature control mode of the second indoor unit 11, the temperature control mode of the first indoor unit 11 is obtained, and the temperature control request of the second indoor unit 11 is not responded to; the first indoor unit 11 is turned on before the second indoor unit 11; and / or

[0160] The temperature control mode with the largest proportion of indoor unit devices (11) is obtained.

[0161] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The outdoor unit 12 is used to: obtain the temperature control mode of the first indoor unit 11 when the temperature control mode of the first indoor unit 11 and the temperature control mode of the second indoor unit 11 are inconsistent, and not respond to the temperature control demand of the second indoor unit 11, with the first indoor unit 11 turning on before the second indoor unit 11; and / or obtain the temperature control mode with the largest number of indoor units 11.

[0162] In this way, high-priority temperature control needs can be met.

[0163] When the air conditioning system 10 includes different indoor unit devices 11, the different indoor unit devices 11 can be in the same temperature control mode or in different temperature control modes.

[0164] The operating modes of the indoor unit 11 may include first-to-open priority mode and multiple-to-open priority mode.

[0165] In the first-to-open priority mode, based on the order in which different indoor unit devices 11 are turned on, the outdoor unit 12 will prioritize responding to the temperature adjustment needs of the first indoor unit device 11 (i.e., the first indoor unit device 11). For the second indoor unit device 11 (i.e., the second indoor unit device 11), if it has a different temperature adjustment mode than the first indoor unit device 11, the outdoor unit 12 will still supply water according to the temperature adjustment mode of the first indoor unit device 11, and will not supply water according to the temperature adjustment mode of the second indoor unit device 11. Furthermore, the outdoor unit 12 will not respond to the temperature adjustment needs of the second indoor unit device 11 until the first indoor unit device 11 meets its temperature adjustment needs. When the indoor unit device 11 meets its temperature adjustment needs, it means that the indoor temperature of the room corresponding to the indoor unit device 11 has reached or is close to the set temperature of the indoor unit device 11, causing the water valve 15 corresponding to the indoor unit device 11 to close and the indoor unit device 11 to enter the air supply state.

[0166] In the multi-operation priority mode, based on the different numbers of indoor unit devices 11 under different temperature control modes, the temperature control mode with the largest number of indoor unit devices 11 can be determined as the first temperature control mode. Then, the outdoor unit device 12 can be controlled to acquire the first temperature control mode and will not acquire other temperature control modes. For other temperature control modes, since the number of corresponding indoor unit devices 11 is less than the number of indoor unit devices 11 in the first temperature control mode, the outdoor unit device 12 will not respond to the temperature control needs of indoor unit devices 11 in other temperature control modes until another temperature control mode has the largest number of indoor unit devices 11.

[0167] Control methods may include:

[0168] Once the indoor temperature reaches the set temperature, the water supply to the corresponding indoor unit 11 will be stopped.

[0169] The control method of this invention can be implemented through the air conditioning system 10 of this invention. Please refer to... Figure 2 The air conditioning system 10 is used to: determine to stop supplying water to the corresponding indoor unit 11 when the indoor temperature reaches the set temperature.

[0170] This helps reduce energy consumption.

[0171] Please combine Figure 2 The air conditioning system 10 includes water valves 15. Each water valve 15 can be installed on a water supply pipe connecting the outdoor unit 12 and a corresponding indoor unit 11. When the indoor unit 11 is in temperature control mode, if the corresponding indoor temperature has not reached the corresponding set temperature, the air conditioning system 10 will keep the water valve 15 open, so that the indoor unit 11 continuously receives water from the outdoor unit 12 through the water supply pipe. If the corresponding indoor temperature reaches the corresponding set temperature, it can be determined that the indoor unit 11 has met the corresponding temperature control requirements, and the air conditioning system 10 will close the water valve 15, so that the outdoor unit 12 stops supplying water to the indoor unit 11 through the water supply pipe, which can reduce the load on the outdoor unit 12 and help reduce energy consumption.

[0172] Additionally, when the water valve 15 corresponding to the indoor unit 11 is closed, the indoor unit 11 will be in air supply mode. In air supply mode, the indoor unit 11 only circulates indoor air by turning on the internal fan, and the corresponding wired controller 13 will not determine the corrected temperature of the indoor unit 11.

[0173] When all indoor units 11 are at the set indoor temperature, it can be determined that the outdoor unit 12 has met the temperature control requirements of all indoor units 11, thus allowing the outdoor unit 12 to be shut down. This avoids prolonged high-load operation of the outdoor unit 12, thereby improving the unit's energy efficiency.

[0174] Please refer to Figure 3 An air conditioning system 10 according to an embodiment of the present invention includes a memory 16 and a processor 17. The memory 16 stores a computer program. When the processor 17 executes the computer program, it implements the steps of the control method of any of the above embodiments.

[0175] For example, when a computer program is executed by processor 17, the control methods that can be implemented include:

[0176] 01: Obtain the corrected temperature, which is determined based on the temperature control mode and set temperature of at least one indoor unit 11, as well as the outdoor temperature and indoor temperature;

[0177] 02: Control the outdoor unit 12 to supply water to at least one indoor unit 11 according to the corrected temperature.

[0178] The aforementioned air conditioning system 10 determines the indoor operating conditions by the indoor temperature, the temperature adjustment mode of the indoor unit 11, and the set temperature, and determines the outdoor operating conditions by the outdoor temperature. This allows the outdoor unit 12 to determine the water supply temperature based on the indoor and outdoor operating conditions, making the water supply temperature more in line with actual needs. Compared with the method of supplying water at a fixed temperature, this helps to reduce energy consumption.

[0179] The processor 17 can be installed on the outdoor unit 12. The wired controller 13 can send information to the outdoor unit 12, so that the processor 17 can process the information sent by the wired controller 13.

[0180] An embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon. When executed by processor 17, the computer program implements the steps of the control method of any of the above embodiments.

[0181] For example, when a computer program is executed by processor 17, the control methods that can be implemented include:

[0182] 01: Obtain the corrected temperature, which is determined based on the temperature control mode and set temperature of at least one indoor unit 11, as well as the outdoor temperature and indoor temperature;

[0183] 02: Control the outdoor unit 12 to supply water to at least one indoor unit 11 according to the corrected temperature.

[0184] The aforementioned computer-readable storage medium determines the indoor operating conditions through the indoor temperature, the temperature adjustment mode of the indoor unit 11, and the set temperature, and determines the outdoor operating conditions through the outdoor temperature, thereby enabling the outdoor unit 12 to determine the water supply temperature based on the indoor and outdoor operating conditions, making the water supply temperature more in line with actual needs. Compared with the method of supplying water at a fixed water temperature, this method is beneficial to reducing energy consumption.
