Description

  The present invention relates to an air conditioning control technique, and more particularly to an air conditioning control technique for controlling an air conditioning environment at a destination in a space.

  Conventionally, an air-conditioning control technique for controlling an air-conditioning environment at a target place in a space using a thermal analysis method has been proposed (see, for example, Non-Patent Document 1). This technology estimates the distribution data indicating the temperature and airflow distribution in the air-conditioned space by forward analysis of the initial air-conditioning condition in the target air-conditioned space, and reverses this distribution data and the target temperature at the destination location. By analyzing, a new control set value related to air conditioning control is estimated, and based on this new control set value, the blowing speed and blowing temperature at the outlet of each air conditioning facility installed in the air-conditioned space are calculated. It is a thing.

In general, in the distributed heat flow analysis method, which is one of the thermal analysis methods, when estimating the control setting value for controlling the air-conditioned space to the target air-conditioned environment, the heating element present in the air-conditioned space affects the air-conditioned environment. It is necessary to consider not only the heat effect but also the heat effect that the adjacent room outside the air-conditioned space and the outside have on the air-conditioning environment. For this reason, in the conventional air conditioning control, boundary condition data is given as data indicating the degree of these effects.
In addition, in the case of estimating a desired control setting value for an air conditioner by using another thermal analysis method such as a concentrated thermal analysis method instead of the distributed system thermal flow analysis method, the boundary condition data is similar to the above. It is to give.

FIG. 6 is a schematic diagram showing a conventional air conditioning control system. Here, in the air conditioning control device, boundary condition data such as the heating element, the adjacent room room temperature, and the outside air temperature is used for inverse analysis to estimate a desired control set value.
The boundary condition data is roughly classified into internal boundary condition data indicating the influence from the inside of the air-conditioned space and external boundary condition data indicating the influence from the outside of the air-conditioned space.

  Typical internal environmental condition data includes heating element data indicating the position, amount of heat generation, shape, etc. of various heating elements such as people and electronic devices existing in the air-conditioned space. In addition, representative examples of external environmental condition data include the room temperature and the adjacent area of the adjacent room on the same floor and upper and lower floors of the air-conditioned space, the outside air temperature and the adjacent area of the external environment adjacent to the air-conditioned space, There is adjacent space data relating to the adjacent space adjacent to the air-conditioned space. For example, those measured by a temperature sensor installed in an adjacent room or outside the building are used as the room temperature and the outside air temperature.

  Normally, the boundary condition data indicating the thermal effect on the air-conditioned space is almost stable or gradually changes, but the external environmental condition data consisting of adjacent space data such as the adjacent room temperature and the outside air temperature is May change drastically. For example, when the cooling in the adjacent room is stopped in summer, the room temperature of the adjacent room may rise rapidly. In addition, the outside air temperature may change suddenly according to changes in weather such as sunshine, wind, rainfall, and snowfall.

  Therefore, according to the prior art, when the temperature in the adjacent space suddenly changes, this is immediately reflected in the boundary condition data, and the control set value estimated by the thermal analysis method also varies greatly. For this reason, although temporarily, there existed a problem that it might become impossible to maintain the air-conditioning environment in an air-conditioning space in an appropriate condition.

  The present invention is for solving such problems, and in the air conditioning control using the thermal analysis method, even if the temperature of the adjacent space adjacent to the air conditioned space fluctuates greatly, the air conditioning environment is brought into an appropriate situation. It aims at providing the air-conditioning control technology which can be maintained.

In order to achieve such an object, an air conditioning control device according to the present invention designates a control set value to an air conditioning system that controls an air conditioning device provided in an air conditioned space, thereby allowing the air conditioned space to be arbitrarily set. An air-conditioning control apparatus that controls to a target air-conditioning environment, a data input unit that acquires a surface temperature of a boundary member that constitutes the air-conditioned space measured in the air-conditioned space, and setting condition data that indicates the configuration of the air-conditioned space And controlling the air-conditioned space to the target air-conditioned environment by inversely analyzing the air-conditioned environment in the air-conditioned space based on boundary condition data indicating the influence on the air-conditioned environment in the air-conditioned space including the surface temperature. and inverse analysis unit that estimates a control set value for the said control setting value estimated by the inverse analysis unit and a conditioning instruction unit for instructing to the air conditioning system, the setting condition data It corresponds to the surface temperature included in the boundary condition data, and includes data indicating the surface area of the boundary member in which the surface temperature is acquired.

  Also, in one configuration example of the air conditioning control device according to the present invention, the data input unit extracts the surface temperature from temperature distribution data detected by an infrared array sensor installed in the air conditioned space. It is a thing.

Further, the air conditioning control method according to the present invention provides an air conditioning control for controlling the air-conditioned space to an arbitrary air-conditioning environment by instructing a control set value to an air-conditioning system that controls the air-conditioning equipment provided in the air-conditioned space. An air conditioning control method used in the apparatus, wherein the data input unit acquires a surface temperature of a boundary member constituting the air conditioned space measured in the air conditioned space, and an inverse analyzing unit includes the air conditioner The air conditioning environment is inversely analyzed based on setting condition data indicating a configuration of the space and boundary condition data indicating an influence on the air conditioning environment in the air conditioning space including the surface temperature. A reverse analysis step for estimating a control set value for controlling the space to the target air-conditioning environment, and an air conditioning instruction unit that calculates the control set value estimated in the reverse analysis step And a conditioning instruction step of instructing to arm, the setting condition data, corresponding to the surface temperature included in the boundary condition data, and includes data indicating the surface area of the boundary member in which the surface temperature is acquired .

  Also, in one configuration example of the air conditioning control device according to the present invention, the data input step extracts the surface temperature from temperature distribution data detected by an infrared array sensor installed in the air conditioned space. It is a thing.

According to the present invention, since the surface temperature of the boundary member constituting the air-conditioned space is used as the boundary condition data, actually, based on the thermal effect that reaches the wall surface from the adjacent room or the outside through the boundary member of the air-conditioned space, A control set value instructed to the air conditioning system can be estimated.
Therefore, unlike the conventional case where the control set value is estimated using the adjacent room temperature or the outside air temperature, mismatch does not occur between the influence of the actual air-conditioned space from the outside and the boundary condition data. For this reason, even if the temperature of the adjacent space adjacent to the air-conditioned space varies significantly, the air-conditioned environment can be maintained in an appropriate state.

It is a block diagram which shows the structure of the air-conditioning control apparatus concerning this Embodiment. It is the schematic which shows the air-conditioning control system concerning this Embodiment. It is a flowchart which shows the air-conditioning control operation concerning this Embodiment. It is a flowchart which shows the air-conditioning control process concerning this Embodiment. It is a simulation result which shows the air-conditioning control action concerning this Embodiment. It is the schematic which shows the conventional air conditioning control system.

First, the principle of the present invention will be described.
In the distributed thermal flow analysis method, which is one of the thermal analysis methods, when estimating the control setting value for controlling the air-conditioned space to the target air-conditioned environment, In order to consider the influence, the room temperature of the next room of the next room, the outside temperature outside the building, etc. are used as boundary condition data. The same applies to the case of using a concentrated thermal analysis method, which is another thermal analysis method, instead of the distributed thermal fluid analysis method.

  For this reason, as described above, when the boundary condition data changes suddenly, the control setting value estimated by the thermal analysis method greatly fluctuates, and as a result, the air-conditioning environment in the air-conditioned space is changed. It may not be possible to maintain an appropriate situation.

  Such a phenomenon is considered to occur by the following mechanism. For example, in the summer, when the cooling of the adjacent room is stopped and the room temperature of the adjacent room rises rapidly, this is input as boundary condition data. Thereby, by the thermal analysis method, the temperature rise of the air-conditioned space is predicted due to the influence exerted on the air-conditioned environment in the air-conditioned space from the adjacent room, and control setting value data that cancels this temperature rise is derived. Therefore, the air conditioning equipment is controlled based on the control set value data, and a phenomenon of temporary excessive decrease in the room temperature occurs.

  At this time, when the boundary condition data changes suddenly, the external influence indicated by the boundary condition data appropriately represents the influence actually received from the outside as a cause of the inappropriate air conditioning environment in the conditioned space. It is possible that there is not. In the above example, the boundary condition data indicates that the temperature rise is larger than the temperature rise actually exerted from the adjacent room.

  Here, if the cause of the mismatch is analyzed in detail between the influence that the air-conditioned space actually receives from the outside and the boundary condition data, it is actually received from the adjacent room compared to the influence indicated by the boundary condition data. It can be seen that the effect of temperature rise is small. This means that the influence of the temperature rise actually received from the outside is mitigated by the boundary members such as the inner wall, the ceiling, and the floor forming the air-conditioned space, and is not immediately affected.

  The present invention focuses on the fact that the temperature change from the outside of the air-conditioned space is mitigated / delayed in the boundary member of the air-conditioned space, and the degree of influence on the air-conditioned environment after passing through the boundary member This is used as data. Specifically, the surface temperature of the boundary member constituting the conditioned space measured in the conditioned space is used as one of the boundary condition data of the thermal analysis method.

Next, an embodiment of the present invention will be described with reference to the drawings.

The operation input unit 12 includes an operation input device such as a keyboard, a mouse, and a touch panel, and has a function of detecting an operator operation and outputting the operation to the arithmetic processing unit 15.
The screen display unit 13 includes a screen display device such as an LCD, and has a function of displaying various information such as an operation menu and input / output data on the screen in response to an instruction from the arithmetic processing unit 15.

The storage unit 14 includes a storage device such as a hard disk or a semiconductor memory, and has a function of storing various processing information and a program 14P used in the arithmetic processing unit 15.
The program 14P is a program that is read and executed by the arithmetic processing unit 15, and is stored in advance in the storage unit 14 via the communication I / F unit 11 from an external device or a recording medium.

The arithmetic processing unit 15 includes a microprocessor such as a CPU and its peripheral circuits, and has a function of realizing various processing units by reading the program 14P from the storage unit 14 and executing it.
As main processing units realized by the arithmetic processing unit 15, there are a data input unit 15A, an inverse analysis unit 15B, and an air conditioning instruction unit 15C.

  The data input unit 15A has a function of storing in the storage unit 14 various processing information used by the arithmetic processing unit 15 input from an external device such as the air conditioning system 20 or a recording medium via the communication I / F unit 11. Based on the surface temperature distribution notified from the air conditioning system 20, it has a function of acquiring the surface temperature of the boundary member constituting the air conditioned space 30 measured in the air conditioned space 30.

  Specific examples of the surface temperature include the surface temperature of boundary members such as an inner wall, a ceiling, a floor, a door, and a window that form the air-conditioned space 30. The data input unit 15A receives the surface temperature distribution measured by the infrared radiation thermometer 24 installed in the air-conditioned space 30 via the communication I / F unit 11, and from this surface temperature distribution, the side wall surface temperature, the ceiling surface A desired surface temperature such as temperature and floor surface temperature is extracted. At this time, based on the position information corresponding to the surface temperature distribution, the temperature at a specific position in the surface temperature distribution may be extracted as a surface temperature representative of the peripheral region. The averaged temperature may be extracted as a representative surface temperature representing the peripheral region.

  The inverse analysis unit 15B calculates a control set value for controlling the air-conditioned space 30 to the target air-conditioning environment by inversely analyzing the boundary condition data 14A, the set condition data 14B, and the target data 14C, and the control set value data And 14D output function.

The inverse analysis unit 15B uses an inverse analysis method in a thermal analysis method such as a distributed system heat flow analysis method or a concentrated system thermal analysis method.
Among them, the distribution system thermal flow analysis method is a technique for obtaining the distribution of the temperature of the space, the air flow, etc. from the boundary conditions by numerical calculation based on CFD (Computational Fluid Dynamics). In general CFD, a target space is divided into mesh-like small spaces, and a heat flow between adjacent small spaces is analyzed.

  The forward analysis in the distributed heat flow analysis method is performed by using a model such as an equation specified in advance from the boundary condition data 14A and the set condition data 14B related to the air-conditioned space 30 and air conditioning such as temperature distribution and air flow distribution in the air-conditioned space 30. This is a technique for calculating the environment, and specifically, a known technique such as Non-Patent Document 2 may be used.

  On the other hand, the inverse analysis in the distributed system heat flow analysis method obtains the sensitivity (or contribution) of the facility to the place where the desired air-conditioning environment is desired by performing the above-mentioned forward analysis, and the control set value is determined by the magnitude of this sensitivity. This is a technique for calculating a final control set value for realizing the target air-conditioning environment by adjustment. Specifically, a known technique such as Non-Patent Document 2 or Non-Patent Document 3 may be used.

  In particular, in the inverse analysis, various known optimization methods can be used. Gradient method that gives initial value of solution (control set value) and gradually updates in the direction that the purpose improves, prepares many initial values, select some of them close to the purpose, and combine their features There is a genetic algorithm that creates the next solution candidate.

On the other hand, the centralized thermal analysis method is a method for determining the temperature of the target space by regarding the target space as one point and calculating the entry and exit of heat at the point. Therefore, although the airflow in the target space cannot be calculated, there is an advantage that the calculation time can be drastically reduced as compared with the distribution method. The target space here may be the whole room or an air conditioning control unit (VAV unit or the like).
In the forward analysis in the centralized thermal analysis method, a solution may be obtained analytically, or all possible candidates may be calculated in a short time without hindering control.

The boundary condition data 14A is data indicating the degree of influence of the air-conditioned space 30 on the air-conditioned environment. For each component whose influence on the air-conditioned environment of the air-conditioned space 30 changes, the boundary conditions at that time point are the wind speed, wind direction / temperature. The degree of influence indicated by is registered.
In particular, in the present invention, the boundary condition data 14A is measured in the air-conditioned space 30 as the degree of influence on the air-conditioned environment after passing through the boundary member that forms the air-conditioned space 30 from the adjacent room or the outside, and is measured by the data input unit 15A. It is assumed that the acquired data indicating the surface temperature of the boundary member constituting the conditioned space 30 is included.

The setting condition data 14B is the space condition data indicating the position and shape related to the components that affect the air-conditioning environment of the air-conditioned space 30 such as the position and shape related to the air-conditioned space 30 and the air outlet of the conditioned air generated by the air-conditioning system 20. In addition, various data serving as setting conditions when performing the heat flow analysis process are included, such as an arrangement position and a heat generation amount regarding each heating element arranged in the air-conditioned space 30, and heating element data indicating a shape.
In particular, in the present invention, the setting condition data 14B includes data indicating the surface area of the wall surface region represented by the surface temperature, corresponding to the surface temperature included in the boundary condition data 14A. .

The target data 14 </ b> C is data indicating the target temperature, comfort, or energy at the target location in the air-conditioned space 30.
The control set value data 14D is data indicating a set value obtained from the supply air temperature, supply air volume, and the like for each air conditioner 22 for controlling the air-conditioned space 30 to the target air-conditioning environment, which is obtained by the inverse analysis unit 15B. is there.

  The air conditioning instruction unit 15C has a function of instructing the air conditioning system 20 via the communication I / F unit 11 of the control setting value included in the control setting value data 14D from the inverse analysis unit 15B.

[Operation of this embodiment]
Next, with reference to FIG. 4, operation | movement of the air-conditioning control apparatus 10 concerning this Embodiment is demonstrated. FIG. 4 is a flowchart showing an air conditioning control process according to the present embodiment.
The arithmetic processing unit 15 of the air conditioning control device 10 starts the air conditioning control process of FIG. 4 at the time of activation or in response to an operator operation.

  Here, a case where a control set value for controlling the air-conditioned space 30 to the target air-conditioning environment is estimated by using a distributed heat flow analysis method will be described as an example. It is assumed that the boundary condition data 14A, the setting condition data 14B, and the target data 14C are stored in the storage unit 14 in advance prior to starting the execution of the air conditioning control process.

  First, the data input unit 15A has the surface of the boundary member that configures the air-conditioned space 30 measured in the air-conditioned space 30 based on the surface temperature distribution from the air-conditioning system 20 input via the communication I / F unit 11. The temperature is acquired and stored in the boundary condition data 14A of the storage unit 14 (step 100).

Next, the inverse analysis unit 15B determines whether it is necessary to update the control setting value instructed to the air conditioning system 20 (step 101). At this time, when the boundary condition data 14A, the setting condition data 14B, or the target data 14C is changed, or when a predetermined time has elapsed since the previous update, it is determined that the control setting value needs to be updated.
If it is determined that updating is not necessary (step 101: NO), the inverse analysis unit 15B waits for a certain period (step 104) and then returns to step 100.

  On the other hand, if it is determined that updating is necessary (step 101: YES), the inverse analysis unit 15B reads the boundary condition data 14A, the setting condition data 14B, and the target data 14C acquired by the data input unit 15A from the storage unit 14. As a control set value for controlling the air-conditioned space 30 to the target air-conditioning environment by performing reverse analysis using a distributed heat flow analysis method, the supply air temperature in each air-conditioning device 22 provided in the air-conditioned space 30 and The supply air volume is estimated and output as control setting data 14D (step 102).

  Subsequently, the air conditioning instruction unit 15C instructs the air conditioning system 20 via the communication I / F unit 11 of the control setting value included in the control setting value data 14D obtained by the inverse analysis unit 15B (step 103). A series of air conditioning control processing ends.

  FIG. 5 is a simulation result showing the air conditioning control operation according to the present embodiment. Here, in summer, the time series change of the room temperature in the air-conditioned space when the cooling of the adjacent room is stopped and the room temperature of the adjacent room rapidly increases is shown. In this case, the set condition data and the target data other than the boundary data are unchanged, and the set room temperature of the air-conditioned space is fixed at 26 ° C.

  In FIG. 5, the characteristic 51 shows the time series change of the room temperature when the adjacent room room temperature or the outside air temperature according to the related art is used as the boundary condition data, and the characteristic 52 is the inner wall, ceiling, It shows the time series change of room temperature when the floor surface temperature is used as boundary condition data.

  According to the characteristic 51, the room temperature of the air-conditioned space once decreases to about 21 ° C. as the adjacent room temperature increases, and then returns to the original room temperature again. Therefore, it is shown that the air-conditioning environment in the air-conditioned space cannot be maintained in an appropriate state, and the people in the air-conditioned space give a discomfort that cannot be ignored and a large energy loss has occurred. I understand.

  On the other hand, according to the characteristic 52, even if the room temperature of the adjacent room rises, the room temperature of the air conditioned space is maintained at the set temperature of 26 ° C. Therefore, it is shown that the air-conditioning environment in the air-conditioned space can be maintained in an appropriate state, and it can be seen that people in the air-conditioned space can be made comfortable and energy loss can also be suppressed.

[Effects of the present embodiment]
Thus, in the present embodiment, the data input unit 15A acquires the surface temperature of the boundary member that configures the air-conditioned space 30 measured in the air-conditioned space 30, and the inverse analyzer 15B configures the air-conditioned space 30. The purpose of the air-conditioned space 30 is to reverse-analyze the air-conditioned environment in the air-conditioned space 30 based on the set condition data 14B indicating the air temperature and the boundary condition data 14A indicating the influence on the air-conditioned environment in the air-conditioned space including the surface temperature. The control setting value for controlling to the air conditioning environment is estimated, and the air conditioning instruction unit 15C instructs the air conditioning system 20 on the control setting value estimated by the inverse analysis unit 15B.

Thereby, since the surface temperature of the boundary member constituting the air-conditioned space is used as the boundary condition data 14A, the air-conditioning is actually performed based on the thermal effect that reaches the wall surface from the adjacent room or the outside through the boundary member of the air-conditioned space 30. A control set value to be instructed to the system 20 can be estimated.
Therefore, unlike the conventional case where the control set value is estimated using the adjacent room temperature or the outside air temperature, mismatch does not occur between the influence of the actual air-conditioned space from the outside and the boundary condition data. For this reason, even if the temperature of the adjacent space adjacent to the air-conditioned space varies significantly, the air-conditioned environment can be maintained in an appropriate state.
