The air handling functional sections of the unit include air mixing, flow balancing, filtration, cooling, primary and secondary heating, dehumidification, humidification, supply fan, return fan, water spray, silencer, heat recovery and other units.
[0003] In the related technology, there are mainly the following schemes for controlling the combined air handling unit:
[0004] Method 1: Constant air volume control, which controls the indoor temperature by keeping the air volume constant. That is, the fixed air supply temperature is used as a parameter and controlled by starting and stopping the unit or variable frequency. This method is difficult to accurately control the temperature of each area, has low thermal comfort, and low energy efficiency.
[0005] Method 2: Variable air volume control, which can adjust the air volume according to the needs of different areas or rooms, can adjust the air volume according to the needs of different areas or rooms to achieve more accurate temperature control. Although it has a certain energy-saving effect compared to constant air volume control, it requires the installation of a large number of sensors, especially the room temperature feedback of indoor temperature sensors to meet thermal comfort. However, a large number of sensor supports increase the construction cost, and there are many buildings in actual projects that cannot provide indoor temperature feedback. Summary of the invention
[0006] In an exemplary embodiment of the present application, a method and electronic device for compensating air supply temperature of a combined air conditioning processing unit are provided to ensure user comfort while improving energy efficiency and reducing costs.

[0019] In the above embodiment, the maximum corrected temperature can be calculated according to the set conditions. However, considering that the outdoor temperature changes over time, the maximum corrected temperature is adjusted in combination with the current outdoor temperature to calculate the actual corrected temperature, and then the target air supply temperature is calculated using the actual corrected temperature. The target air supply temperature calculated in this way combines the real-time conditions of the indoor temperature and the outdoor temperature, and the calculation result is more accurate.

[0029] The target supply air temperature is determined to be between the maximum and minimum values of the initial supply air temperature range.
[0030] In the above embodiment, when the target supply air temperature exceeds the maximum and minimum values of the initial supply air temperature range, it may exceed the control temperature of the target air conditioning unit. Therefore, it can be determined that the target supply air temperature is between the maximum and minimum values of the initial supply air temperature range.
[0031] In an optional embodiment, the method further includes:
[0032] Determine at least one room associated with the target air conditioning unit according to the three-dimensional model;
[0033] Among the at least one associated room, a target most unfavorable room associated with the target air conditioning handling unit is determined.
[0034] In the above embodiment, since the target air conditioning unit is responsible for controlling a large number of rooms, a target most unfavorable room may be selected and determined, and the target supply air temperature calculated by using the target most unfavorable room is more accurate.

[0038] Determine at least one room with the highest natural room temperature as the target most unfavorable room.
[0039] In the above embodiment, since the target air conditioning unit is responsible for controlling many rooms, a target most unfavorable room can be selected and determined. This process not only takes into account the building materials and functional properties, but also takes into account the changes in the natural room temperature of each room, so that the determined target most unfavorable room is more consistent with the actual situation. Therefore, the target supply air temperature calculated by using the target most unfavorable room is more accurate.

[0072] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0073] In the related technology, when controlling the combined air handling unit, constant air volume control is difficult to accurately control the temperature of each area, resulting in low thermal comfort and low energy efficiency; variable air volume control requires the installation of a large number of sensors, especially room temperature feedback from indoor temperature sensors to meet thermal comfort. However, a large number of sensor supports increase the construction cost, and in actual projects, there are many buildings that cannot provide indoor temperature feedback.
[0074] To this end, the embodiment of the present application provides a combined air conditioning unit supply air temperature compensation method, in which the target air supply temperature of each air conditioning unit can be calculated in real time without installing an indoor temperature sensor, and then the target air supply temperature is applied to the corresponding air conditioning unit to supply air, thereby ensuring user comfort and reducing costs.
[0075] After introducing the design ideas of the embodiments of the present application, the following briefly introduces the application scenarios to which the technical solutions of the embodiments of the present application can be applied. It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of the present application and are not limited. In specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.
[0076] refer to Figure 1 , shows a structural schematic diagram of a combined air conditioning processing unit, which is mainly composed of three parts: air handling equipment, air transportation equipment and air distribution device.
[0077] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.
[0078] Combine the following Figure 1 The application scenario shown is shown in Figure 2 A flow chart of a method for compensating air supply temperature of a combined air conditioning processing unit is shown to illustrate the technical solution provided in an embodiment of the present application.
[0079] S201: Display the three-dimensional model of the target building.
[0080] S202: In response to an operation performed on the three-dimensional model, determining a target air-conditioning unit.
[0081] The target air conditioning processing unit is any one of the multiple air conditioning processing units.
[0082] S203: In response to the user's temperature compensation operation on the target air conditioning unit, display the target air supply temperature.
[0083] In the embodiment of the present application, a three-dimensional model of the target building is constructed to simulate the change of the natural room temperature of each room with the outdoor temperature, determine the target most unfavorable room corresponding to the target air-conditioning unit, and then calculate the dynamic compensation value of the target air-conditioning unit with the change of the outdoor temperature, that is, the target air supply temperature, and then use the target air supply temperature to control the target air-conditioning unit to supply air. The differentiated air supply temperature of each air-conditioning unit is precisely controlled to achieve energy-saving effects while meeting the thermal comfort level, without the need to install indoor temperature sensors, saving costs.
[0084] Regarding S201, based on the actual building structure and function of the project, a three-dimensional model containing all rooms is established using simulation software. This model can accurately reflect the layout and structural characteristics of the building, including room distribution, external maintenance structure, door and window settings, floors and other geometric details. The external environment of the building also needs to be considered to ensure the integrity and accuracy of the model.
[0085] In order to ensure that the simulation results are consistent with the actual situation, detailed parameter settings can be made for the three-dimensional model. The specific parameter settings include: building material properties, defining thermal parameters such as thermal conductivity, density, specific heat capacity, etc. of each part of the material; enclosure structure parameters, setting thermal performance parameters of enclosure structures such as exterior walls, floor slabs, roofs, doors and windows, and floors, including thermal insulation and sealing; room functional properties, setting internal heat source parameters according to the purpose of the room, such as the power of lighting equipment, equipment heat dissipation, number of people, and load of the fresh air system.
[0086] In the embodiment of the present application, the building targeted is referred to as a target building, and a plurality of air conditioning units are deployed in the target building. After obtaining the three-dimensional model of the target building, the three-dimensional model can be displayed on a display screen.
[0087] In S202, since multiple air conditioning units are deployed in the target building, each air conditioning unit is associated with at least one room, and the association here means that each air conditioning unit can control the temperature of at least one room. In the embodiment of the present application, the target air conditioning unit can be determined by operating the sub-models of multiple air conditioning units presented by the three-dimensional model, that is, the target air supply temperature of the target air conditioning unit is calculated next.
[0088] In S203, in response to the user's temperature compensation operation on the target air conditioning unit, the target air supply temperature of the target air conditioning unit is calculated and displayed, and the target air conditioning unit supplies air according to the target air supply temperature. In actual application, the target air supply temperature of other air conditioning units can also be calculated in the same way, which is not repeated here.
[0089] Figure 3 A display page for determining a target air conditioning group provided in an embodiment of the present application; wherein n is an integer, wherein, Figure 3 In (a), the user selected air conditioning unit 4. Figure 3 (b) in the figure is the room associated with the air conditioning unit 4, including, for example, room 401, ..., room 410. 4 is a schematic diagram of a target most unfavorable room provided in an embodiment of the present application, for example, the icon of the most unfavorable room can be displayed in bold. Figure 5 A page diagram showing a target air supply temperature is provided in an embodiment of the present application.
[0090] Specifically, Figure 6A flow chart of a method for determining a target air supply temperature provided in an embodiment of the present application, Figure 6 At least the following steps are included:
[0091] S601: Calculate the maximum corrected temperature of the target most unfavorable room according to the first temperature, the second temperature, the third temperature, the fourth temperature, and the difference between the maximum value and the minimum value of the initial air supply temperature range of the target air conditioning unit.
[0092] Among them, the first temperature T 1 , the second temperature T 2 , the third temperature T 3 , the fourth temperature T 4 , and the initial supply air temperature range of the target air conditioning unit (T 02 ,T 01 ) and their calculation methods are as follows:
[0093] The first temperature T 1 The maximum natural room temperature of the target most unfavorable room during the cooling period. The cooling period can be from June 1 to October 31 every year. The method for determining the target most unfavorable room and the law of its natural room temperature change can be found as follows: Figure 4 and Figure 5 , and then the highest natural room temperature of the target most unfavorable room during the cooling period (for example, occurring on October 15) can be determined.
[0094] The second temperature T 2 is the indoor design temperature of the target most unfavorable room. The indoor design temperature of each most unfavorable room is determined according to the functional attributes of the most unfavorable room (office, equipment room). At the same time, the indoor design temperature is not higher than the maximum outdoor temperature during the cooling period. The maximum outdoor temperature is based on the "Standard for Meteorological Parameters in Building Design" and is determined according to the meteorological parameters of the cooling period. For example, it can be 38°C. In the actual application process, the functional attributes of the most unfavorable rooms with different functions determine that the minimum indoor design temperature of the most unfavorable room can be 23°C. That is to say, under normal circumstances, the indoor design temperature of each most unfavorable room is between 23°C and 38°C.
[0095] The third temperature T 3 It is the highest natural room temperature of the most unfavorable room corresponding to each air-conditioning unit during the cooling period.
[0096] Fourth temperature T 4 It is the minimum value of the indoor design temperature of the most unfavorable room corresponding to each air-conditioning unit during the cooling period.
[0097] The initial supply air temperature range of the target air conditioning unit (T 02 ,T 01) can be flexibly set according to the specific situation of the project and the actual needs of the building. This setting needs to be based on design specifications, building functions, indoor comfort requirements, and external environmental factors (such as climate conditions, building orientation, etc.). This setting must not only meet industry standards, but also consider the use characteristics of each room in the project, heat load distribution and other parameters, so it has a certain degree of flexibility and adjustability. In actual projects, T 01 It can be 26℃, T 02 It can be taken at 20℃.
[0098] Optionally, the maximum corrected temperature of the target most unfavorable room is calculated by the following formula:
[0099]
[0100] Among them, F max is the highest corrected temperature of the most unfavorable room in the target, T 1 is the first temperature, T 2 is the second temperature, T 3 is the third temperature, T 4 is the fourth temperature, T 01 is the maximum value of the initial air supply range, T 02 It is the minimum value of the initial air supply range.
[0101] For example, the first temperature is 34.7°C, the second temperature is 25°C, the third temperature is 43.3°C, the fourth temperature is 23°C, the maximum value of the initial air supply range is 26°C, and the minimum value of the initial air supply range is 20°C. Therefore, it can be calculated that the maximum corrected temperature of the target most unfavorable room is 2.87°C.
[0102] S602: adjusting the maximum correction temperature according to the fourth temperature, the fifth temperature, and the sixth temperature to obtain a corrected temperature.
[0103] Among them, the fifth temperature T 5 , the sixth temperature T 6 The meaning and calculation method of are as follows:
[0104] Fifth temperature T 5 is the current outdoor temperature, which can be obtained through a temperature sensor or weather forecast; the sixth temperature T 6 It is the maximum outdoor temperature during the cooling period.
[0105] Since the maximum corrected temperature is calculated under the set conditions, but the actual outdoor temperature will change over time, it is necessary to adjust the maximum corrected temperature to obtain the real-time corrected temperature. Optionally, the formula for calculating the corrected temperature is as follows:
[0106]
[0107] Among them, F is the corrected temperature of the most unfavorable room of the target, F max is the highest corrected temperature of the most unfavorable room in the target, T 4 is the fourth temperature, T 5 is the fifth temperature, T 6 is the fifth temperature. 5 -T 4 Indicates the change of the current outdoor temperature relative to the reference temperature; T 6 -T represents the change in the maximum outdoor temperature relative to the reference temperature during the cooling period.
[0108] For example, the fourth temperature is 23° C., the fifth temperature is 30° C., and the sixth temperature is 38° C. Therefore, the corrected temperature can be calculated to be 1.34° C.
[0109] S603: Apply the correction temperature to adjust the maximum value and / or the minimum value of the initial air supply temperature range of the target air conditioning unit to obtain the target air supply temperature.
[0110] When the outdoor temperature rises, the supply air temperature needs to be lowered to offset the effect of the external heat. By subtracting the correction temperature (dynamic compensation value) from the maximum value (highest set point) of the initial supply air temperature range, it is ensured that the supply air temperature is not too high at high outside temperatures, thus avoiding excessive indoor temperatures.
[0111] The target air supply temperature may be 24.66°C, which is the maximum value of the initial air supply temperature range of 26°C minus the correction temperature of 1.34°C.
[0112] In addition, in order to ensure accurate air supply, it is also possible to determine that the target air supply temperature is between the maximum and minimum values of the initial air supply temperature range. In the above example, 24.66°C is between 20°C and 26°C, so the target air conditioning unit can be controlled to supply air according to the target air supply temperature. If the calculated target air supply temperature is greater than the maximum value of the initial air supply temperature range, the maximum value of the initial air supply temperature range can be used as the target air supply temperature; if the calculated target air supply temperature is less than the minimum value of the initial air supply temperature range, the minimum value of the initial air supply temperature range can be used as the target air supply temperature.
[0113] Figure 7 A flow chart of a method for determining the most unfavorable target room provided in an embodiment of the present application, Figure 4 At least the following steps are included:
[0114] S701: Determine at least one room associated with the target air conditioning unit according to the three-dimensional model.
[0115] Since each air conditioning unit is associated with at least one room, the at least one room associated with the target air conditioning unit can be determined based on the three-dimensional model. Specifically, the air conditioning partitions covered by the air conditioning units on each floor are determined using the established three-dimensional model, and the room range served by each air conditioning unit is delineated to ensure that all rooms within the control range of the unit are included, and then the rooms that can be controlled by the target air conditioning unit can be determined.
[0116] S702: Determine the target most unfavorable room associated with the target air conditioning unit in at least one associated room.
[0117] The target most unfavorable room is a room in which some or all of the natural room temperature, frequency of use, functional importance and environmental exposure conditions meet the set conditions in at least one room associated with the target air-conditioning unit.
[0118] in, Figure 8 A more detailed flow chart of a method for determining the most unfavorable target room provided in an embodiment of the present application is provided. Figure 8 At least the following steps S702-1 to S702-3 are included.
[0119] S702-1: Based on the three-dimensional model and set parameters, determine the natural room temperature variation pattern of each room included in the target building.
[0120] The set parameters include the building materials and functional properties of the target building. Based on the established three-dimensional model and set parameters, the hourly temperature of each room is simulated, and the natural room temperature change curve of each room is simulated based on a time span of 8760 hours in 365 days and 24 hours a year. The simulation results will show the changes of the natural room temperature of each room with the outside temperature under different climatic conditions, which is convenient for analyzing the temperature change law of each room, especially the temperature fluctuation under extreme climate. Therefore, the natural room temperature change law of each room included in the target building can be determined.
[0121] Exemplarily, the process can be implemented by simulation software in the relevant technology (such as the Swell series software - ITES), that is, the software is used to simulate the changes in the natural room temperature of each room with the outdoor temperature, so as to evaluate the temperature change pattern in the room in different seasons and time periods.
[0122] S702-2: Determine the natural room temperature of at least one room associated with the target air conditioning unit at the current moment.
[0123] For example, if the current time is Friday, October 25, 2024, the natural room temperature of each room at the current time can be determined based on the natural room temperature change rules of each room determined above.
[0124] S602-3: Determine the room with the highest natural room temperature among at least one room as the target most unfavorable room.
[0125] Optionally, the room with the highest natural room temperature can be used as the target most unfavorable room. Specifically, within the room range covered by each air conditioning unit, the change of the natural room temperature of each room is analyzed. According to the simulation data, the maximum values of the natural room temperatures of different rooms are compared using data analysis tools (such as Excel, Python or Matlab), and the room with the highest natural room temperature is determined as the target most unfavorable room.
[0126] In addition, although the room with the highest natural room temperature is usually the first choice for the most unfavorable room, in actual projects, the selection of the most unfavorable room does not only depend on the absolute value of the natural room temperature, but is a comprehensive trade-off of multiple factors. During the design, the selection of the most unfavorable room may be re-evaluated based on multiple factors such as the frequency of use of the room, functional importance, environmental exposure, equipment heat generation, etc.
[0127] Therefore, in order to improve accuracy, the frequency of use, functional importance, and environmental exposure of each room can also be considered to determine the target most unfavorable room. For example, although a room has a high natural room temperature, if the room has fewer functions or is not frequently used (such as a storage room, spare room, etc.), its actual impact on the air conditioning system load is small. Therefore, even if the room has the highest natural room temperature, it may not be suitable as the most unfavorable room. In this case, another room that is actually frequently used and has a higher temperature may be selected as the most unfavorable room, that is, as the target most unfavorable room associated with the target air conditioning unit.
[0128] In the embodiment of the present application, when there is a lack of indoor temperature feedback (when it is impossible to install an indoor sensor), there is no need to increase costs. Based on outdoor dynamic meteorological parameters, building energy consumption simulation software is used to simulate the changes in the natural room temperature of each room as the outdoor temperature changes. The room with the highest natural room temperature in the room range corresponding to the unit is determined as the most unfavorable room, and the dynamic compensation value of the unit's supply air temperature that changes with the outdoor temperature is calculated. The supply air temperature of each air handling unit is accurately compensated in real time for dynamic temperature, so as to achieve air conditioning energy saving while meeting thermal comfort requirements.
