Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of combined air conditioner air supply, and in particular to a combined air conditioner handling unit air supply temperature compensation method and electronic equipment. BACKGROUND

[0002] A combined air conditioner unit is an air handling device assembled by various air handling function segments. The air handling function segments of the unit include air mixing, flow equalization, filtration, cooling, primary and secondary heating, dehumidification, humidification, air supply fan, return air fan, water injection, sound attenuation, heat recovery, and the like.

[0003] In related technologies, 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 supply constant. That is, a fixed air supply temperature is taken as a parameter, and the unit is started or frequency converted to control it. This method is difficult to accurately control the temperature of each region, has low thermal comfort, and has low energy efficiency.

[0005] Method 2: Variable air volume control, which can adjust the air volume according to the needs of different regions or rooms, and can adjust the air volume according to the needs of different regions or rooms to achieve more accurate temperature control. Although it has certain energy-saving effect compared with constant air volume control, a large number of sensors need to be installed, especially indoor temperature sensors to provide room temperature feedback to meet the 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

[0006] In the exemplary embodiments of the present application, a combined air conditioner handling unit air supply temperature compensation method and electronic equipment are provided to ensure user comfort while improving energy efficiency and reducing cost.

[0007] According to a first aspect in the exemplary embodiments, a combined air conditioner handling unit air supply temperature compensation method is provided, comprising:

[0008] displaying a three-dimensional model of a target building; wherein the target building is deployed with a plurality of air conditioner units;

[0009] determining a target air conditioner unit in response to an operation on the three-dimensional model; wherein the target air conditioner handling unit is any one of the plurality of air conditioner handling units;

[0010] displaying a target air supply temperature in response to a user temperature compensation operation on the target air conditioner handling unit;

[0011] The target air supply temperature instructs the target air conditioning unit to supply air; the target air supply temperature is determined based on the first temperature, the second temperature, the third temperature, the fourth temperature, the fifth temperature, the sixth temperature and the initial air supply temperature range of the target air conditioning unit;

[0012] The first temperature is the highest natural room temperature of the target most unfavorable room during the cooling period; the second temperature is the indoor design temperature of the target most unfavorable room; the third temperature is the highest natural room temperature of the most unfavorable room corresponding to each air-conditioning unit during the cooling period; the fourth temperature is the minimum value of the indoor design temperature of the most unfavorable room corresponding to each air-conditioning unit during the cooling period; the fifth temperature is the current outdoor temperature; and the sixth temperature is the highest outdoor temperature during the cooling period.

[0013] The target most unfavorable room is a room in at least one room associated with the target air-conditioning unit, in which some or all of the natural room temperature, usage frequency, functional importance and environmental exposure conditions meet the set conditions.

[0014] This embodiment of the application constructs a three-dimensional model of the target building, simulates how the natural room temperature of each room changes with the outdoor temperature, determines the target least favorable room corresponding to the target air conditioning unit, and then calculates the dynamic compensation value of the target air conditioning unit as the outdoor temperature changes, namely the target supply air temperature. This target supply air temperature is then used to control the air supply of the target air conditioning unit. This achieves precise control of the differentiated supply air temperature of each air conditioning unit, achieving energy savings while meeting thermal comfort requirements, without the need for installing indoor temperature sensors, and thus saving costs.

[0015] In an optional embodiment, the method further includes:

[0016] Calculating a maximum corrected temperature of the target most unfavorable room based on 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 supply air temperature range of the target air conditioning unit;

[0017] Adjusting the maximum repair temperature according to the fourth temperature, the fifth temperature, and the sixth temperature to obtain a corrected temperature;

[0018] The correction temperature is applied to adjust the maximum value and / or the minimum value of the initial supply air temperature range of the target air conditioning unit to obtain the target supply air temperature.

[0019] In the above embodiment, a maximum corrected temperature is calculated based on the set conditions. However, considering that outdoor temperature varies over time, the maximum corrected temperature is adjusted based on the current outdoor temperature to calculate the actual corrected temperature. This actual corrected temperature is then used to calculate the target supply air temperature. This method calculates the target supply air temperature by incorporating the real-time conditions of both indoor and outdoor temperatures, resulting in a more accurate result.

[0020] In an optional implementation, the maximum correction temperature of the target most unfavorable room is calculated 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 processor, and the maximum correction temperature of the target most unfavorable room is calculated, including:

[0021]

[0022] Wherein, F max is the maximum correction temperature of the target most unfavorable room, T1 is the first temperature, T2 is the second temperature, T3 is the third temperature, T4 is the fourth temperature, and T 01 is the maximum value of the initial air supply range, and T 02 is the minimum value of the initial air supply range.

[0023] The above embodiment applies this method to calculate the maximum correction temperature, considers temperature values at different levels, and the calculation result is more accurate.

[0024] In an optional implementation, the maximum correction temperature is adjusted according to the fourth temperature, the fifth temperature, and the sixth temperature, and the correction temperature is obtained, including:

[0025]

[0026] Wherein, F is the correction temperature of the target most unfavorable room, F max is the maximum correction temperature of the target most unfavorable room, T4 is the fourth temperature, T5 is the fifth temperature, and T6 is the fifth temperature.

[0027] The above embodiment considers the current outdoor temperature when calculating the correction temperature, and the maximum correction temperature can be updated in combination with the current temperature condition to obtain the correction temperature conforming to the current actual situation.

[0028] In an optional implementation, after the maximum value and / or the minimum value of the initial air supply temperature range of the target air conditioning processor are adjusted by using the correction temperature to obtain the target air supply temperature, the method further includes:

[0029] It is determined that the target air supply temperature is located between the maximum value and the minimum value of the initial air supply temperature range.

[0030] In the above embodiment, when the target air supply temperature exceeds the maximum value and the minimum value of the initial air supply temperature range, the target air conditioning processor may exceed the control temperature at this time, and therefore it can be determined that the target air supply temperature is located between the maximum value and the minimum value of the initial air supply temperature range.

[0031] In an optional implementation, the method further includes:

[0032] According to the three-dimensional model, at least one room associated with the target air conditioning processing unit is determined;

[0033] In the at least one associated room, a target most unfavorable room associated with the target air conditioning processing unit is determined.

[0034] In the above embodiment, since the target air conditioning unit is responsible for controlling a large number of rooms, one target most unfavorable room can be selected and determined, and the target supply air temperature calculated by applying the target most unfavorable room is more accurate.

[0035] In an optional implementation, in the at least one associated room, the target most unfavorable room associated with the target air conditioning processing unit is determined, including:

[0036] Based on the three-dimensional model and the set parameters, the natural room temperature variation law of each room included in the target building is determined; wherein the set parameters include the building materials and the functional attributes of the target building;

[0037] The natural room temperature of each room associated with the target air conditioning processing unit at the current time is determined.

[0038] The room with the highest natural room temperature in the at least one room is determined as the target most unfavorable room.

[0039] In the above embodiment, since the target air conditioning unit is responsible for controlling a large number of rooms, one target most unfavorable room can be selected and determined, and the target supply air temperature calculated by applying the target most unfavorable room is more accurate.

[0040] In an optional implementation, the method further includes:

[0041] According to the natural room temperature variation law of the most unfavorable room, the highest natural room temperature of the most unfavorable room in the cooling period is determined.

[0042] In the above embodiment, since the natural room temperature variation law of the most unfavorable room is determined, the natural room temperature at different periods, for example, the highest natural room temperature in the cooling period, can be determined.

[0043] In an optional implementation, the method further includes:

[0044] According to the functional attributes of the most unfavorable room, the indoor design temperature of the most unfavorable room is determined; wherein the indoor design temperature is not higher than the highest outdoor temperature in the cooling period; wherein the highest outdoor temperature is determined according to the meteorological parameters in the cooling period.

[0045] The above embodiment considers the functional attribute and the highest outdoor temperature in the cooling period when calculating the indoor design temperature of each most unfavorable room, so that the calculated indoor design temperature of the most unfavorable room is more accurate.

[0072] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in a clear and complete manner with reference to the drawings in the embodiments of the present application.

[0073] In related technologies, in the control of a combined air handling unit, fixed air volume control is difficult to accurately control the temperature of each region, has low thermal comfort, and has low energy efficiency; variable air volume control needs to install a large number of sensors, especially the room temperature feedback of indoor temperature sensors to meet the thermal comfort. However, a large number of sensor supports increase the construction cost, and in actual projects, there are a large number of buildings that cannot provide indoor temperature feedback.

[0074] Therefore, the embodiments of the present application provide a combined air conditioning handling unit supply air temperature compensation method, in which no indoor temperature sensor needs to be installed, the target supply air temperature of each air conditioning unit can be calculated in real time, and then the target supply air temperature is applied to the supply air of the corresponding air conditioning handling unit. The user comfort is ensured, and the cost is reduced.

[0075] After introducing the design idea of the embodiments of the present application, the application scenarios to which the technical solutions of the embodiments of the present application can be applied will be briefly introduced below. It should be noted that the following introduced application scenarios are only used to illustrate the embodiments of the present application but not to limit. In the specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0076] ReferenceFigure 1 , shows a structural schematic diagram of a combined air conditioning processing unit. The combined air conditioning processing unit is mainly composed of three parts: air handling equipment, air delivery equipment and air distribution device.

[0077] To further illustrate the technical solutions provided by the embodiments of the present application, the following is a detailed description of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative work. In 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 embodiments of the present application.

[0078] The following combination Figure 1 The application scenario shown, refer to Figure 2 A flow chart of a method for compensating the 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 a three-dimensional model of a target building.

[0080] S202: In response to an operation 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 supply air temperature.

[0083] This embodiment of the application constructs a three-dimensional model of the target building, simulates how the natural room temperature of each room changes with the outdoor temperature, determines the target least favorable room corresponding to the target air conditioning unit, and then calculates the dynamic compensation value of the target air conditioning unit as the outdoor temperature changes, namely the target supply air temperature. This target supply air temperature is then used to control the air supply of the target air conditioning unit. This achieves precise control of the differentiated supply air temperature of each air conditioning unit, achieving energy savings while meeting thermal comfort requirements, without the need for installing indoor temperature sensors, and thus 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] To ensure that the simulation results are consistent with the actual situation, detailed parameter settings can be made on the three-dimensional model, including: building material properties, defining the thermal conductivity, density, and specific heat capacity of each part of the material; building envelope parameters, setting the thermal performance parameters of the building envelope, including the thermal insulation and sealing of the external wall, floor, roof, door and window, and ground; room function attributes, setting internal heat source parameters according to the room purpose, such as the power of lighting equipment, equipment heat dissipation, number of personnel, and load of fresh air system.

[0086] In the embodiments of the present application, the building to be 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 the display screen.

[0087] S202 is involved. Since a plurality of 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 embodiments of the present application, the target air conditioning unit can be determined by operating the sub-models of the plurality of air conditioning units presented by the three-dimensional model, that is, the target supply air temperature of the target air conditioning unit is to be calculated next.

[0088] S203 is involved. In response to the user's temperature compensation operation on the target air conditioning processing unit, the target supply air temperature of the target air conditioning unit is calculated and displayed, and the target air conditioning unit supplies air according to the target supply air temperature. In actual application, the target supply air temperature of other air conditioning units can also be calculated in the same way, which is not described here.

[0089] Figure 3 The present application provides a display page for determining a target air conditioning unit; wherein n is an integer, wherein, Figure 3 (a) in the user selects the air conditioning processing unit 4, Figure 3 (b) in the room associated with the air conditioning processing unit 4, for example, including room 401, …, room 410. 4 is a schematic diagram of a target most unfavorable room provided by the embodiments of the present application, for example, the icon of the most unfavorable room can be displayed in bold. Figure 5 The present application provides a page diagram for displaying the target supply air temperature.

[0090] Specifically, Figure 6 The present application provides a method flow chart for determining the target supply air temperature, Figure 6 at least including the following steps:

[0091] S601: 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 supply air temperature range of the target air conditioning processing unit, the highest correction temperature of the target most unfavorable room is calculated.

[0092] Among them, the first temperature T1, the second temperature T2, the third temperature T3, the fourth temperature T4, and the initial air supply temperature range (T 02 ,T 01 ) and its calculation method are as follows:

[0093] The first temperature T1 is the highest 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 in the following 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 T2 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 of Building Design" and is determined according to the meteorological parameters of the cooling period. For example, it can be 38°C. In actual application, 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 T3 is the highest natural room temperature of the most unfavorable room corresponding to each air-conditioning processing unit during the cooling period.

[0096] The fourth temperature T4 is the minimum value of the indoor design temperature of the most unfavorable room corresponding to each air-conditioning processing 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 circumstances 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 comply with industry standards, but also take into account parameters such as the use characteristics of each room in the project and heat load distribution, so it has a certain degree of flexibility and adjustability. In actual projects, T 01 It can be taken as 26℃, T 02 You can take 20℃.

[0098] Optionally, calculate the maximum corrected temperature of the target most unfavorable room using the following formula:

[0099]

[0100] Among them, F max is the highest corrected temperature of the most unfavorable room, T1 is the first temperature, T2 is the second temperature, T3 is the third temperature, T4 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, and 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, the maximum corrected temperature of the target most unfavorable room can be calculated to be 2.87°C.

[0102] S602: Adjust the maximum correction temperature according to the fourth temperature, the fifth temperature, and the sixth temperature to obtain a corrected temperature.

[0103] The meaning and calculation method of the fifth temperature T5 and the sixth temperature T6 are as follows:

[0104] The fifth temperature T5 is the current outdoor temperature, which can be obtained through a temperature sensor or a weather forecast; the sixth temperature T6 is the maximum outdoor temperature during the cooling period.

[0105] Since the maximum corrected temperature is calculated under set conditions, but the actual outdoor temperature will change over time, it is necessary to adjust the maximum corrected temperature to obtain a 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 T5 is the maximum corrected temperature of the target most unfavorable room, T4 is the fourth temperature, T5 is the fifth temperature, and T6 is the fifth temperature. T5-T4 represents the change in the current outdoor temperature relative to the baseline temperature; T6-T represents the change in the maximum outdoor temperature relative to the baseline 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: Applying the correction temperature, adjusting the maximum value and / or the minimum value of the initial supply air temperature range of the target air-conditioning unit to obtain a target supply air temperature.

[0110] When the outdoor temperature rises, the supply air temperature needs to be reduced to offset the influence of external heat. By subtracting the correction temperature (dynamic compensation value) from the maximum value (highest set value) of the initial supply air temperature range, it can be ensured that the supply air temperature will not be too high at high external temperatures, thereby avoiding excessive indoor temperature.

[0111] In which the target supply air temperature can be the maximum value 26℃ of the initial supply air temperature range minus the correction temperature 1.34℃, which is 24.66℃.

[0112] In addition, in order to ensure accurate air supply, the target supply air temperature can also be determined to be between the maximum and minimum values of the initial supply air temperature range. In the above example, 24.66℃ is between 20℃ and 26℃, so the target air conditioning handler can be controlled to supply air at this target supply air temperature. If the calculated target supply air temperature is greater than the maximum value of the initial supply air temperature range, the maximum value of the initial supply air temperature range can be used as the target supply air temperature; if the calculated target supply air temperature is less than the minimum value of the initial supply air temperature range, the minimum value of the initial supply air temperature range can be used as the target supply air temperature.

[0113] Figure 7 A method flowchart for determining a target most unfavorable room provided by an embodiment of the present application, Figure 4 at least comprising the following steps:

[0114] S701: Determine at least one room associated with the target air conditioning handler according to the three-dimensional model.

[0115] Since each air conditioning handler is associated with at least one room, at least one room associated with the target air conditioning handler can be determined according to the three-dimensional model. Specifically, using the established three-dimensional model, the air conditioning partition covered by the air conditioning handler in each layer is determined, the room range served by each air conditioning handler is demarcated to ensure that all rooms within the control range of the handler are included, and then the room controlled by the target air conditioning handler can be determined.

[0116] S702: In the at least one associated room, determine the target most unfavorable room associated with the target air conditioning handler.

[0117] In which the target most unfavorable room is a room in the at least one room associated with the target air conditioning handler, in which some or all of the natural room temperature, usage frequency, functional importance, and environmental exposure meet the set conditions.

[0118] In which, Figure 8 A more detailed method flowchart for determining a target most unfavorable room provided by an embodiment of the present application, Figure 8 at least comprising the following steps S702-1 to S702-3.

[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 target building's building materials and functional attributes. Based on the established 3D model and these parameters, hourly temperature simulations are performed for each room. The natural room temperature variation curve for each room is simulated over a time span of 8,760 hours, 365 days a year, and 24 hours a day. The simulation results demonstrate how the natural room temperature in each room changes with the outside air temperature under different climate conditions, facilitating analysis of temperature variations in each room, particularly temperature fluctuations in extreme climates. This allows the determination of the natural room temperature variation patterns for each room in the target building.

[0121] Exemplarily, this process can be implemented through simulation software in related technologies (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 as the outdoor temperature changes, so as to evaluate the temperature change patterns 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 selected as the target least favorable room. Specifically, within the room range covered by each air conditioning unit, analyze the variation in natural room temperature in each room. Based on the simulation data, use a data analysis tool (such as Excel, Python, or Matlab) to compare the maximum natural room temperatures of different rooms and determine the room with the highest natural room temperature as the target least favorable room.

[0126] Furthermore, while the room with the highest natural temperature is often chosen as the least favorable room, in actual projects, the selection of the least favorable room depends not solely on the absolute value of the natural temperature but rather on a comprehensive balance of multiple factors. During design, the selection of the least favorable room may be re-evaluated based on factors such as frequency of use, functional importance, environmental exposure, and equipment heat generation.

[0127] Therefore, in order to improve the accuracy, the use frequency, functional importance, and environmental exposure of each room can also be considered to determine the target most unfavorable room. For example, although the natural room temperature of a certain room is relatively high, if the room has less function or is not frequently used (such as a storage room, a standby room, etc.), its actual influence on the load of the air conditioning system is small. Therefore, even if the natural room temperature of the room is the highest, it can not be suitable as the most unfavorable room.
