Here, the technical significance of the virtual room temperature measurement value equivalent to the room temperature measurement value of the air-conditioned space 50 derived by the virtual state measurement value deriving unit 15D according to the present invention will be described in detail with reference to FIG. In the present embodiment, the air-conditioned space 50 is configured to perform air-conditioning control for each of the zones Z1 to Z4.

  FIG. 4 is a diagram illustrating an example of an arrangement state of persons existing in the zone Z1 of the air-conditioned space 50. As shown in FIG. 4, in the zone Z1 whose target temperature is 26 ° C., a space Z1-a whose temperature estimated by the distribution system flow analysis unit 15B (hereinafter referred to as “estimated temperature”) is 26 ° C., There is a space Z1-b whose estimated temperature is 28 ° C. In addition, the position and the number of persons existing in the zone Z1 are detected by the human sensor HS1 (the point indicated by ◆ in the figure is a person), and there are seven persons in the space Z1-a. In the space Z1-b, there is one person.

In general, when air-conditioning control is performed so that an air-conditioned space that is the target of air-conditioning control becomes a target temperature, air-conditioning control is performed by feedback control based on the difference between the measured value of the room temperature of the air-conditioned space and the target temperature. The
The air-conditioning control by feedback control is to obtain a difference (operation amount difference) with respect to the immediately preceding operation amount corresponding to the deviation between the target temperature of the air-conditioned space and the measured value corresponding to the room temperature of the air-conditioned space, and based on this operation amount difference. In this control, the room temperature of the air-conditioned space is brought close to the target temperature by blowing out the conditioned air from the outlet.

  In the present embodiment, when the air conditioning control by the feedback control is executed, the “virtual room temperature measured value” derived by the virtual state measured value deriving unit 15D is the measured value of the room temperature of the air conditioned space. That is, in the present embodiment, air conditioning control is performed by feedback control based on the difference between the target temperature of the air-conditioned space and the virtual room temperature measurement value derived by the virtual state measurement value deriving unit 15D.

<Principle of the present invention>
In air-conditioning control using feedback control, after a period of time has elapsed since the start of air-conditioning control to guide the target space to the target temperature, the air-conditioning control that is appropriate for the target temperature is inappropriate. There may be a mixture of air-conditioned spaces.
For example, when the state of the air-conditioned space that has passed for a while after the start of air-conditioning control is the state shown in FIG. 4A, the space Z1-a whose estimated temperature is 26 ° C. is the target temperature of the zone Z1. It can be said that the air conditioning control is appropriate for (26 ° C.), while the space Z1-b whose estimated temperature is 28 ° C. is a space where the air conditioning control is inappropriate for the target temperature. It can be said that there is.

In the conventional air-conditioning control by feedback control, even in a situation where a space where appropriate air-conditioning control is performed and a space where inappropriate air-conditioning control is performed are mixed in the air-conditioned space, the zone Z1 In general, the average value of the estimated temperatures at any point in the temperature distribution is set to the room temperature measurement value Tp1 of the zone Z1.
As a specific example, the measured value Tp1 of the room temperature can be an average value of the estimated temperature at the position of the person existing in the zone Z1, and in the case of FIG.
Tp1 = (26 × 7 + 28 × 1) ÷ 8 = 26.25 ° C.
It becomes. Further, the estimated temperature of the space where people in the zone Z1 are concentrated can be set to the room temperature measurement value Tp1, and in the case of FIG. 4A, the room temperature measurement value Tp1 of the zone Z1 is Because people are concentrated on Z1-a,
Tp1 = 26 ° C
It becomes.

In the above-described conventional technology, when the condition of the air-conditioned space is as shown in FIG. 4A, the measured value Tp1 of the room temperature in the zone Z1 and the target temperature in the zone Z1 are approximate values. Air-conditioning control is performed by feedback control that blows out conditioned air in an operation amount that maintains the current temperature distribution from the outlet. That is, air conditioning control is performed to maintain the temperature distribution of the spaces Z1-a and Z1-b in the zone Z1.
However, the estimated temperature of the space Z1-b is 28 ° C., and the air conditioning control that maintains this temperature distribution is executed even though the air conditioning control is inappropriate for the target temperature. For this reason, in the space Z1-b, the air conditioning control inappropriate for the target temperature is continuously executed.

In the present invention, by such feedback control, a state in which a space in which air conditioning control appropriate to the target temperature is performed and a space in which air conditioning control is inappropriate is continuously mixed in the air conditioning space. In consideration of the fact that the air-conditioning space is measured, the measured value of the room temperature in the air-conditioned space is derived in consideration of the relationship between the location of people in the air-conditioned space and the estimated temperature distribution in the air-conditioned space. The air conditioning control is executed by feedback control based on the difference between the measured value of the room temperature in the space and the target temperature.
For example, the air-conditioning control apparatus 10 according to the present embodiment derives a measured value of the room temperature of the air-conditioned space in consideration of the relationship between the density of people in the air-conditioned space and the estimated temperature distribution of the air-conditioned space. By executing the air-conditioning control by feedback control based on the difference between the measured value and the target temperature, the air-conditioning control appropriate for the target temperature is applied to the entire air-conditioned space regardless of the presence or absence of people in the air-conditioned space. It is made to be made.

  Specifically, when the condition of the air-conditioned space is shown in FIG. 4B, the weight deriving unit 15D-1 of the air-conditioning control apparatus 10 according to the present embodiment exists in the zone Z1 based on the arrangement information 14D. A weighting coefficient indicating the density of a person is derived according to the position of the person. It should be noted that the values (M1 to M8) of the derived weighting factors are the values (M1 to M7) corresponding to the positions of people existing in the space Z1-a where people are densely populated. The characteristic is that the value is smaller than the value (M8) corresponding to the position of the person in the isolated space Z1-b, and the sum of the derived weighting coefficient values is 1.

When the weighting coefficient corresponding to each position in the zone Z1 is derived, the calculation unit 15D-2 of the air conditioning control device 10 extracts the estimated temperature at the position corresponding to the weighting coefficient from the estimated temperature distribution data 14C, and the estimated temperature The virtual room temperature measurement value VTp of the zone Z1 is calculated by adding all the values multiplied by the weighting coefficient corresponding to. As shown in FIG. 4B, when the estimated temperature of the space Z1-a is 26 ° C. and the estimated temperature of the space Z1-b is 28 ° C., the virtual room temperature measurement value VTp is
VTp = (M1 + M2 + M3 + M4 + M5 + M6 + M7) × 26 + M8 × 28
Can be calculated.
Assuming that the calculated virtual room temperature measurement value VTp of the zone Z1 is 27 ° C., the air conditioning control instruction unit 15E sets the target temperature Tp = 26 ° C. of the zone Z1 and the calculated virtual room temperature measurement value VTp = 27. The operation amount of the conditioned air is determined based on the difference from ° C., and the air conditioning system 40 is instructed to execute the air conditioning control with the operation amount.

<Derivation method of weighting factor>
Here, a method for deriving the weighting factor derived by the weight deriving unit 15D-1 will be specifically described.
As described above, the weighting factor derived by the weight deriving unit 15D-1 has a low value corresponding to the position of the person existing in the space where the person is dense, while the weight coefficient is derived in the space where the person is sparse. There is a feature that the value corresponding to the position of the person existing in is high. Kriging estimation of an average value is known as a method for obtaining a weighted average of data in which the phenomenon of interest has a spatial correlation and a close position has a close value.
Kriging estimation of the average value is a method for calculating a representative value of data by calculating a weighted average when data is measured at an arbitrary n point position, and is calculated by (Equation 1) shown below. The

Here, in (Equation 1), W _α represents a weighting factor, Z represents a measured value of data, and X _α represents a position vector. Further, by using the weighting coefficient W _α calculated from the linear simultaneous equation of (Expression 2) shown below, the estimated error variance of the representative value calculated by (Expression 1) can be made as small as possible.

  Here, μ in (Expression 2) represents a Lagrange multiplier. The function C represents a covariance function C (h), and is assumed to be a function shown in (Equation 3) as a Gaussian covariance function, for example.

An expression expressing the above linear simultaneous equations (Expression 2) in a matrix form is shown in (Expression 4), and an expression concisely expressed in (Expression 5-1). By solving the linear simultaneous equations for the vector w to the weight coefficient W _alpha and μ the element, it is possible to calculate the weight coefficient W _n at the position of any of n points.
Specifically, as shown in (Equation 5-2), by applying the n + 1-order inverse of the matrix K ^M to both sides, it is possible to obtain a vector w.

Next, with reference to FIG. 5, operation | movement of the air-conditioning control apparatus 10 concerning this Embodiment is demonstrated. FIG. 5 is a flowchart showing the air conditioning control process of the air conditioning control device 10 according to the present embodiment.

  If there is no difference between the virtual room temperature measurement value and the target temperature value (“NO” in step S105), the air conditioning control device 10 instructs the air conditioning control instruction unit 15E to maintain the current operation amount. While outputting to the air conditioning system 40, an air conditioning control process is started anew (step S101). Alternatively, after the current operation amount is maintained, the air conditioning control process may be terminated, and the standby state may be maintained until the start of the air conditioning control process according to the operation of the operator.

  On the other hand, if there is a difference between the virtual room temperature measurement value and the target temperature value (“YES” in step S105), the air conditioning control instruction unit 15E responds to the difference between the virtual room temperature measurement value and the target temperature value. The air conditioning system 40 is controlled by determining the operating amount of the conditioned air and instructing the determined operating amount to the air conditioning processing device 41 (step S106).

As described above, according to the present embodiment, in the air-conditioned space, the temperature distribution (state distribution) in the air-conditioned space obtained by the distributed heat flow analysis method and the arrangement of people in the air-conditioned space are determined. A room temperature measurement value in consideration of the degree of crowding of existing people, that is, a virtual room temperature measurement value (virtual state measurement value) is derived, and this virtual room temperature measurement value and the target temperature of the air conditioning space (state target value) The air-conditioning environment in the air-conditioned space can be adjusted by a feedback control operation based on the difference from the value of.

For example, as shown in FIG. 7A, the zone Z1 is divided into regions A1 to A3 in accordance with the arrangement situation of people present in the zone Z1 that is the air-conditioned space.

The representative state value deriving unit 25D-2 obtains the room temperature measurement values of the regions divided by the dividing unit 25D-1 for each region divided based on the estimated temperature distribution data 14C output by the distribution system flow analysis unit 15B.

In the present embodiment, as shown in FIG. 7A, the representative state value deriving unit 25D-2 estimates the representative temperatures of the regions A1 to A3 obtained by dividing the zone Z1 from the estimated temperature distribution data 14C.

  For example, when it is estimated from the estimated temperature distribution data 14C that the estimated temperature at the center position of the region A1 is 26 ° C., the representative temperature of the region A1 can be set to 26 ° C. Similarly, if the estimated temperature at the center position of the region A2 is estimated to be 26 ° C., the representative temperature of the region A2 is set to 26 ° C.

In the present embodiment, the virtual state value calculating unit 25D-4 divides the calculation operation of the average value of the representative temperature by the average calculating unit 25-D by the dividing unit 25D-1 as shown in FIG. 7C. The virtual room temperature measurement value of the air-conditioned space 50 is calculated by repeatedly executing the plurality of areas that have been integrated into one area C1. Specifically, as shown in FIGS. 7A to 7C, among the plurality of regions in the zone Z1, first, the adjacent regions A1 and A2 are integrated into the region B1 to calculate the representative temperature. Then, the virtual room temperature measurement value of the zone Z1 is calculated by integrating the adjacent areas B1 and A3 in the zone Z1 into the area C1 and calculating the representative temperature.

  Regarding the method for deriving the virtual room temperature measurement value by the virtual state measurement value deriving unit 25D in the present embodiment, when the air-conditioned space 50 is divided into arbitrary regions, the weighting factor described in the first embodiment is used.
