[0002] In Class A or even super-Class A office buildings, there will be offices with an area of ​​over 1,000 square meters to accommodate multiple people. Such large offices require multiple central air-conditioning fan coil units for cooling. The fan coil units are spaced but not necessarily evenly distributed in large offices. Each fan coil unit only directly cools the area where it exhausts air. Therefore, large offices can be divided into multiple areas according to the number of fan coil units. The air between areas will circulate, and will affect each other when the temperatures set on different fan coil units are different. After the fan detects that the area where it is located has reached the set temperature, the variable frequency air conditioner runs at a low speed with a certain proportion of the fixed frequency to adjust the slight temperature loss. However, the fixed frequency setting is the factory value, and it is difficult to maintain the temperature for a long time.

[0036] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention provides an air conditioning control method based on area adjacent relationship, which is used to solve the problem in the prior art that the constant frequency temperature maintenance efficiency of fans in adjacent areas is low, affecting the user's air conditioning usage experience.

[0038] See also Figure 1 , Figure 1 A first flow chart of an air conditioning control method based on area neighbor relationship provided in an embodiment of the present invention.

[0039] S100, obtaining historical temperature data of each area, identifying the first time interval when the temperature of the area to be temperature controlled is actively controlled, obtaining the starting time node and the ending time node, and obtaining the corresponding air conditioning power change function of the area to be temperature controlled in the first time interval; judging whether the temperature change rate of the starting time node and the ending time node exceeds a threshold value in the historical temperature data of the area not to be temperature controlled, and identifying the adjacent area;

[0040] It should be noted that, in the present embodiment, the central air-conditioning in the office building will be provided with a user control panel at each fan, and real-time temperature detection records will be available in each area. The temperature control system terminal can centrally obtain and process the data of each fan control, and then the temperature control system can obtain the historical temperature data of each area, specifically a function of temperature change over time. The selected historical temperature data should be close to the time when the temperature influence coefficient is calculated. Such a temperature change function can reflect the regional temperature influence situation more accurately. For example, the historical temperature data can be updated once a day after the central air-conditioning in the office is started. The area to be temperature-controlled is the corresponding area of ​​the central air-conditioning that needs to adjust the air-conditioning power in the subsequent steps, but in this step, each area affected by the temperature of the adjacent area is It can be used as the area to be temperature controlled; in the temperature control system of the central air conditioner, the starting time node for active temperature control of the area to be temperature controlled is identified by identifying the control instructions of the user control panel. After the area to be temperature controlled reaches the user-specified temperature, the fan temperature control work will be suspended, which is the end time node, and the first time interval is obtained; in adjacent areas where the temperatures affect each other, when the area to be temperature controlled is actively temperature controlled, the fan starts to supply air and stops supplying air, which will cause the temperature of the adjacent areas to change significantly. It can be determined whether it is affected by the area to be temperature controlled based on the temperature change rate of the non-temperature controlled area at the starting time node and the end time node. The preset temperature change rate threshold is set according to the fan coil specifications to identify multiple adjacent areas affected by the area to be temperature controlled;

[0041] S200, obtaining the temperature change value of the temperature-controlled area within the first time interval, and constructing a temperature influence model according to the temperature change function and the air conditioning power change function to obtain the temperature influence coefficient of the adjacent area. The temperature influence model is specifically:

[0042]

[0043] Among them, f m (x) is the temperature change function of the mth adjacent area, F(x) is the temperature change function of the area to be temperature controlled, P(x) is the air conditioning power change function, θ is the cooling efficiency, P0 is the preset heat generation power, t1 and t2 are the starting time node and the end time node of the first time interval respectively, ΔT is the temperature change value, V is the spatial volume of the area to be temperature controlled, δ is the specific heat of air per unit volume, is the temperature influence coefficient of the mth associated area, and a is the number of adjacent areas;

[0044] It should be noted that the temperature control system can monitor and adjust the power of fan coil units at various locations. Based on the refrigeration efficiency of the central air conditioner, the power can be converted into cooling capacity per unit time. The total cooling capacity in the first time interval is partly lost by the heat-generating body in the area to be temperature-controlled, and partly lost by the influence of the adjacent area. The remaining cooling capacity is the work done on the temperature of the area to be temperature-controlled. During the temperature change process of the area to be temperature-controlled, the central air conditioner will adjust the output power by frequency conversion due to the temperature change. The power change function can be integrated in the first time interval and multiplied by the refrigeration efficiency to obtain the total cooling capacity in the first time interval. The volume of the area to be temperature-controlled is preset based on the fan distribution in the office, the office area and the floor height. The temperature change value of the area to be temperature-controlled in the first time interval is the temperature change to be achieved by the active temperature control performed in the first time interval, that is, the temperature difference of the area to be temperature-controlled at the starting time node and the end time node. The number of workstations arranged in a large office in an office building is related to the heat generation of the number of workers and the heat generation of office supplies, and the number of workstations is related to the area of ​​the area, which can be preset according to the area of ​​the area to be temperature-controlled and adjusted according to actual conditions.

[0045] In an office building, it is necessary to ensure that the indoor and outdoor air are isolated, and an insulation layer will be built on the facade of the building. Therefore, this embodiment does not consider the temperature exchange with the temperature of the exterior wall, and the adjacent area will also have fan coils to discharge air, and there will be temperature changes in the first time interval. The heat exchange between the adjacent area and the area to be temperature controlled is basically convection heat exchange. The temperature influence can refer to the convection heat exchange formula, which is only related to the temperature difference between the adjacent area and the area to be temperature controlled, the heat exchange area and the convection heat transfer coefficient. The temperature influence coefficient The dimension is j / (s·℃). The temperature influence coefficient reflects the heat exchange area and convection heat transfer coefficient between the adjacent area and the area to be temperature controlled. Although the adjacent area is connected to the area to be temperature controlled, there may be obstacles such as screens or they are only connected by windows and doorways, which affects the actual heat exchange area. The multi-temperature influence model constructed by the data of the first time interval consistent with the number of adjacent areas is required to calculate the temperature influence coefficient of each associated area, that is, the simultaneous polynomials:

[0046]

[0047] Among them, t 2m-1 and t 2m They are respectively the starting time node and the ending time node of the mth first time interval; by calculating the simultaneous equations, the temperature influence coefficient of each associated area can be obtained for subsequent calculations.

[0048] S300, receiving a temperature adjustment instruction for the area to be temperature controlled, obtaining the temperature of the area to be temperature controlled and the temperature of the adjacent area after the temperature adjustment is completed, and calculating the temperature maintenance power of the area to be temperature controlled according to a temperature control model, wherein the temperature control model is specifically:

[0049]

[0050] Among them, ΔP is the temperature maintenance power, T0 is the current temperature of the area to be temperature controlled, T m is the current temperature of the mth associated area, and θ is the cooling efficiency.

[0051] It should be noted that, at present, central air conditioners use variable frequency controllers to adjust the cooling speed with fuzzy control technology when actively controlling the temperature. After reaching the set temperature, the variable frequency air conditioner in this embodiment does not use a certain proportion of fixed frequency power to operate at a low speed, but uses the temperature maintenance power to calculate the main temperature loss in the temperature control area and accurately compensate for it, and sets the air conditioning power of the temperature control area to be set to the temperature maintenance power; when the fan in the temperature control area maintains the temperature with the temperature maintenance power, the adjacent area may also actively adjust the temperature through temperature control. Therefore, the temperature control signal of the adjacent area can be detected in the temperature control system. When the active temperature control of the adjacent area is completed, the temperature control model is recalculated with the updated temperature of the adjacent area, and the temperature maintenance power is updated.

[0052] In this embodiment, by obtaining historical temperature data of each area in a large office, the adjacent areas are identified with the data associated when the temperature-controlled area is actively temperature-controlled, and the temperature influence model is constructed with the data of the temperature-controlled area and the adjacent areas. The temperature influence coefficient reflecting the heat exchange area and the convective heat transfer coefficient between the adjacent areas and the temperature-controlled area is calculated. After the active temperature adjustment of the temperature-controlled area is completed, the temperature maintenance power is calculated with the temperature control model of the temperature influence coefficient, and the regional temperature is maintained with precise frequency conversion, thereby extending the temperature maintenance time and improving the user's air-conditioning experience.

[0053] The above is a detailed description of the first embodiment of an air conditioning control method based on area neighboring relations provided by the present application. The following is a detailed description of the second embodiment of an air conditioning control method based on area neighboring relations provided by the present application.

[0054] In this embodiment, an air conditioning control method based on the adjacent relationship of regions is further provided. In the aforementioned step S100, in the historical temperature data of the non-temperature-controlled region, it is determined whether the temperature change rate of the starting time node and the end time node exceeds the threshold, and the adjacent region is identified, specifically:

[0055] The temperature change function of the area not to be temperature controlled is derived to obtain the temperature change rate function, and it is identified whether the absolute values ​​of the temperature change rates corresponding to the starting time node and the end time node exceed the preset threshold value. If so, it is determined whether the positive and negative values ​​of the temperature change rate of the area not to be temperature controlled at the time node are consistent with the temperature change trend of the area to be temperature controlled. If so, the area not to be temperature controlled is identified as an adjacent area;

[0056] It should be noted that in the case where the distribution relationship of multiple fan coil units in an office may be staggered, although the areas corresponding to two fan coil units are in the same large office, they are not necessarily directly adjacent, and there are other areas in between. Therefore, the temperatures of the areas corresponding to the two fan coil units will not affect each other; after differentiating the temperature change function of the area not to be temperature controlled, a function of the temperature change rate changing with time can be obtained. When the area not to be temperature controlled is adjacent to the area to be temperature controlled, when the temperature control area is actively temperature controlled, no matter what the temperature difference between the two areas is, the area not to be temperature controlled will have obvious temperature fluctuations. There are also some cases where the area not to be temperature controlled is adjacent to the area to be temperature controlled. If the areas to be temperature controlled are adjacent but have little influence on each other's temperature, then the temperature fluctuation is small and not obvious, and they can be regarded as non-adjacent. Therefore, the absolute value of the temperature change rate corresponding to the starting time node and the end time node can be used to determine whether the temperature fluctuation is in an adjacent area; further, it is necessary to determine whether the positive and negative values ​​of the temperature change rate of the area not to be temperature controlled at the time node are consistent with the temperature change trend of the area to be temperature controlled, that is, when the area to be temperature controlled is cooling down, the temperature change trend of the area not to be temperature controlled as an adjacent area should also cool down, that is, the temperature change rate is negative. After both criteria are met, the area not to be temperature controlled can be identified as an adjacent area.

[0057] Furthermore, in the aforementioned step S200, before obtaining the temperature change value of the area to be temperature-controlled within the first time interval, it also includes: obtaining the total number of fans and the total area of ​​the current office, identifying the regional temperature rise rate under consistent temperature in historical data, calculating the regional area corresponding to the fan according to the temperature rise rate, and calculating the corresponding regional space volume according to the regional area and the floor height. It should be noted that in the case of uneven distribution of fans in a large office, the regional area corresponding to each fan is difficult to calculate directly. Therefore, when the office temperature is unified and the fans are running at the same power, the regional area corresponding to each fan can be calculated based on the proportional relationship of the temperature rise rate. The regional area that each fan should correspond to can be calculated based on the standard temperature rise rate and the corresponding unit area proportional relationship, d m vm =d0v0, d0 is the standard temperature rise rate, v0 is the unit area, d m is the area corresponding to the mth wind turbine, v m is the temperature rise rate of the area corresponding to the mth fan. The larger the area, the smaller the temperature rise rate under the same fan air supply power and temperature, thus establishing a proportional relationship. The floor height can be directly obtained based on the building data, and the floor height multiplied by the area can be used to obtain the regional space volume, which is used for calculation in the temperature influence model.
