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 target place in a space using a distributed heat flow analysis method.

  When maintaining the desired air-conditioned environment in the space, air-conditioning equipment is provided in the air-conditioned space that should be air-conditioned, temperature sensors are arranged at positions representative of each area of the air-conditioned space, and air-conditioning equipment is provided according to the output of the temperature sensor The amount of operation, such as the air volume, wind direction, and temperature, of the conditioned air supplied from is determined.

  On the other hand, in large spaces such as offices, work efficiency is usually given priority to the arrangement of people, lighting, electrical equipment, etc. that are heat sources, and the arrangement of desks, chairs, partitions, etc. that impede air flow. Such an indoor layout is not designed with priority on air conditioning control. For this reason, the positional relationship between the air outlet of the air conditioner and the temperature sensor is inevitably so-called temperature interference (see, for example, Non-Patent Document 1).

  Therefore, in a configuration in which a plurality of general single-loop feedback control systems are configured, the operation amount becomes difficult to be stabilized due to such temperature interference, and good control becomes difficult. For example, if the temperature change width is large when shifting to the desired air conditioning environment, the control state will vary, and the feedback control system will individually search for the stable state of the entire system, The operation amount becomes unstable.

  As a method of obtaining a stable operation amount for such an air-conditioned space where complicated temperature interference occurs, a method using a distributed system heat flow analysis method can be considered. By using this distributed system heat flow analysis method, based on the set design goal, the perturbation adjoint equation for the nonlinear problem for the design goal is solved, and the design goal is defined as the change rate of the design parameter. By analyzing the sensitivity, a desired thermal convection field or material diffusion field can be designed (see, for example, Patent Document 1).

  Therefore, the distribution system thermal flow analysis method is used to estimate the temperature and airflow distribution of the air-conditioned space from the input air-conditioning status of the air-conditioned space, and to obtain this distribution and the target temperature at the target location in the air-conditioned space. Based on this sensitivity data, calculate the sensitivity indicating the degree of change in wind speed, wind direction and temperature in each small space provided in the air-conditioned space necessary to satisfy the target temperature. It is possible to calculate an operation amount that includes the blowing speed and blowing temperature of the conditioned air and the suction speed for sucking room air from each suction port.

  Thereby, since a desired environmental state is analyzed as a whole system stable state, a stable operation amount can be obtained, and it is possible to efficiently approach a desired thermal environment state. In particular, even when it is difficult to determine a set value, such as when air conditioning is activated, the target thermal environment state can be reached in a short time by setting the manipulated variable using the distributed thermal flow analysis method.

  However, such a distributed system heat flow analysis method is merely a simulation, and it is necessary to model an air-conditioned space to be controlled, a disturbance, or the like. Therefore, even if the air conditioning equipment is controlled by the obtained operation amount, there is a problem that, for example, a temperature error may occur between the estimated temperature distribution by simulation and the temperature distribution in the actual air conditioned space.

  The present invention is for solving such problems, and an object of the present invention is to provide an air conditioning control technique capable of correcting an error that occurs when air conditioning control is performed with an operation amount obtained by a distributed heat flow analysis method. .

  In order to achieve such an object, the air conditioning control device according to the present invention estimates the temperature and air flow distribution of the air-conditioned space from the air-conditioning state of the input air-conditioned space using a distributed heat flow analysis method. And a heat flow analysis processing unit that estimates an operation amount related to air conditioning control based on this distribution and a target temperature at a target location in the air conditioning space, and based on the operation amount obtained by the heat flow analysis processing unit. An air conditioning control device that performs air conditioning estimation control for controlling the air conditioning environment of the entire air conditioned space by adjusting the blowing speed and temperature of the conditioned air at each air outlet provided in the air conditioned space with an air conditioning system, Air-conditioning feedback control determination for determining whether to switch to air-conditioning feedback control based on an end condition for the effect of air-conditioning estimation control defined in advance after starting air-conditioning estimation control And an air conditioning instruction unit that instructs the air conditioning system to start executing the air conditioning feedback control operation using the estimated temperature as a set temperature when switching to the air conditioning feedback control is determined by the air conditioning feedback control determination unit. Yes.

  At this time, the air-conditioning feedback control determination unit confirms whether or not the temperature field is stable at the target location by comparing the measured temperature change at the specific target location and the steady-state determination temperature width at a certain determination time. When the stability of the temperature field at the place is confirmed, switching to air conditioning feedback control for the target place may be determined.

  In addition, after the air conditioning feedback control determination unit starts the air conditioning estimation control, the temperature error between the measured temperature and the reference temperature consisting of the estimated temperature at the specific target location obtained by the heat flow analysis processing unit is used as the temperature error. On the other hand, the switching to the air-conditioning feedback control for the target place for correcting the temperature error may be determined by comparing with a preset allowable range.

  In addition, the air conditioning feedback control determination unit compares the measured temperature with the reference temperature consisting of the measured temperature retroactively measured from the measured temperature at a specific target location, and measures the target location obtained. The measured temperature gradient at the target location is calculated from the temperature change, the measured temperature at the target location is equal to or higher than the estimated temperature at the target location, and the measured temperature gradient corresponds to the preset temperature error. In the above case, and when the measured temperature of the target location is lower than the estimated temperature of the target location and the measured temperature gradient is smaller than the reference gradient of the measured temperature corresponding to the preset temperature error, Switching to air conditioning feedback control may be determined.

  The air conditioning feedback control determination unit may determine switching to the air conditioning feedback control when a certain standby time has elapsed since the start of the air conditioning estimation control.

  In addition, the air conditioning control method according to the present invention estimates the temperature and air flow distribution of the air-conditioned space from the input air-conditioning status of the air-conditioned space using a distributed heat flow analysis method, and the distribution and the air-conditioned space. A heat flow analysis processing unit that estimates an operation amount related to air conditioning control based on a target temperature at a target location in the interior, and is provided in the air-conditioned space based on the operation amount obtained by the heat flow analysis processing unit An air-conditioning control method used in an air-conditioning control device that performs air-conditioning estimation control for controlling the air-conditioning environment of the entire air-conditioned space by adjusting the blow-out speed and temperature of the conditioned air at each blow-out outlet by an air-conditioning feedback control After the control determination unit starts the air-conditioning estimation control, the control determination unit determines to switch to the air-conditioning feedback control based on the end condition of the effect of the air-conditioning estimation control defined in advance When the air conditioning feedback control determination step and the air conditioning instruction unit determine that switching to the air conditioning feedback control is performed in the air conditioning feedback control determination step, the air conditioning system starts the execution of the air conditioning feedback control operation with the estimated temperature as the set temperature. An air conditioning instruction step for instructing the air conditioning.

  At this time, the air-conditioning feedback control determination step confirms whether or not the temperature field at the target location is stable by comparing the measured temperature change at the specific target location and the steady-state determination temperature width at a certain determination time. When the stability of the temperature field at the place is confirmed, switching to air conditioning feedback control for the target place may be determined.

  In the air conditioning feedback control determination step, after the air conditioning estimation control is started, the temperature error between the measured temperature and the reference temperature composed of the estimated temperature at the specific target location obtained by the heat flow analysis processing unit is determined as the temperature error. In contrast, the switching to the air-conditioning feedback control for the target location for correcting the temperature error may be determined by comparing with a preset allowable range.

  In the air conditioning feedback control determination step, the measured temperature is compared with a reference temperature consisting of the measured temperature measured at a specific target location retroactively from the measured temperature for a fixed determination time. The measured temperature gradient at the target location is calculated from the temperature change, the measured temperature at the target location is equal to or higher than the estimated temperature at the target location, and the measured temperature gradient corresponds to the preset temperature error. In the above case, and when the measured temperature of the target location is lower than the estimated temperature of the target location and the measured temperature gradient is smaller than the reference gradient of the measured temperature corresponding to the preset temperature error, Switching to air conditioning feedback control may be determined.

  In the air conditioning feedback control determination step, switching to the air conditioning feedback control may be determined when a certain waiting time has elapsed since the start of the air conditioning estimation control.

  According to the present invention, it is possible to adjust an error that occurs when air-conditioning control is performed with the operation amount obtained by the distributed heat flow analysis method, by an individual air-conditioning feedback control operation for the target location by the air-conditioning system. Therefore, a comfortable air-conditioning environment set by the resident can be provided to the resident in the air-conditioned space.

The arithmetic processing unit 15 of the air conditioning control device 10 starts the air conditioning control process of FIG. 7 at the time of activation or according to an operator operation. It is assumed that the setting condition data 14A is stored in the storage unit 14 in advance prior to the start of execution of the air conditioning control process.

And boundary condition data 14B such as suction speeds u, v, and w (three-dimensional components) at each suction port, and measured temperature data 14C indicating the measured temperature T _M at the target location j in the air-conditioned space 30 are acquired. (Step 100).

  Next, the heat flow analysis processing unit 15B acquires the setting condition data 14A from the storage unit 14 (step 101), and based on the setting condition data 14A and the boundary condition data 14B generated by the data input unit 15A, The distribution data 14D indicating the temperature and airflow distribution in the air-conditioned space 30 is calculated by forwardly analyzing the condition of the air-conditioned space 30 using the distributed heat flow analysis method (step 102).

Thereafter, the heat flow analysis processing unit 15B acquires the target data 14E indicating the target temperature at the target location in the air-conditioned space 30 by the operator's data input operation using the operation input unit 12 (step 103). By comparing the data 14E with the distribution data 14D, it is confirmed whether or not there is a divergence regarding the destination location of the conditioned space 30 (step 104).

[Air conditioning feedback control operation]
Next, with reference to FIG. 2 and FIG. 8, the air-conditioning feedback control operation of the air-conditioning control apparatus according to this embodiment will be described.
The arithmetic processing unit 15 of the air conditioning control device 10 starts the air conditioning feedback control process of FIG. 8 after the above-described air conditioning estimation control process of FIG. 7 is executed.

A measured temperature change ΔT _MM (absolute value) indicating a change in measured temperature T _M in minutes is calculated (step 111).
Here, the measured temperature change [Delta] T _MM, compares the steady determination temperature range T _D set in advance in the storage unit 14 (step 112), if the measured temperature change [Delta] T _MM is greater than the steady determination temperature range T _D (Step 112: NO), the air conditioning feedback control determination unit 15C returns to Step 110 and repeatedly confirms until the temperature field at the target location j is stabilized.

On the other hand, when the measured temperature change [Delta] T _MM is within constant determined temperature range T _D (step 112: YES), since the temperature field was confirmed that the stable in a subject where j, conditioned feedback control determining section 15C is The estimated temperature T _S is extracted as the reference temperature of the target location j from the distribution data 14D obtained by the heat flow analysis processing unit 15B (step 113), and the estimated temperature T _S of the target location j at the current time t and the actual temperature are extracted. A temperature error ΔT _SM (absolute value) with the measured temperature T _M is calculated (step 114).

Here, the temperature error [Delta] T _SM, compared with the allowable range T _L which is set in advance in the storage unit 14 (step 115), if the temperature error [Delta] T _SM is larger than the allowable range T _L (Step 115: YES), conditioning feedback control determining section 15C, the temperature error [Delta] T _SM determines switching to air-conditioning the feedback control to the target location j for correcting a new set temperature estimated temperature T _S of the target location j in the target location j T _SP Is notified to the air conditioning instruction unit 15D (step 116).

The air conditioning instruction unit 15D uses the communication I / F unit 11 to start the execution of the air conditioning feedback control operation using the estimated temperature T _S at the target location j as the set temperature T _SP based on the set temperature data 14G. The system is instructed (step 117), and the series of air conditioning feedback control processing is terminated.

On the other hand, if the temperature error [Delta] T _SM is within the allowable range T _L (step 115: NO), the air conditioning feedback control determining section 15C ends the series of air-conditioning feedback control process.

At t, it decreases monotonously to the temperature T ^t _M.

Here, the time t ₁ corresponds to a time that is earlier than the current time t by the determination time Δt, and the measured temperature change ΔT _MM is obtained by ΔT _MM = abs (T ^t1 _M −T ^t _M ). . The function abs () is a function for obtaining an absolute value.
The measured temperature change [Delta] T _MM is, if it is within the constant determined temperature range T _D, the temperature field is stable in a subject location j, the measured temperature change [Delta] T _MM is not transient, the air conditioning to the subject location j It is determined that it should be corrected by feedback control.

Further, the temperature error ΔT _SM is obtained by ΔT _SM = abs (T _S −T ^t _M ). If this temperature error ΔT _SM is larger than the allowable range T _L , the difference between the estimated temperature T _S and the actual measured temperature T _M at the target location j is large, and therefore the target location for correcting this temperature error ΔT _SM. Switching to air conditioning feedback control for j is determined. Then, the air conditioning system 20 starts an air conditioning feedback control operation with the estimated temperature T _S at the target location j as the set temperature T _SP .

[simulation result]
FIG. 10 is a configuration example of an air-conditioned space that is an object of air conditioning. Here, four air outlets A, B, C and D and nine air inlets are arranged on the ceiling of the air-conditioned space 30, and there are three heating elements made of a personal computer or the like on the floor of the air-conditioned space 30. is doing. In the air-conditioned space 30, a target location i that is an object of air-conditioning estimation control and a target location j that is an object of air-conditioning feedback control are set.

FIG. 11 is an explanatory diagram showing simulation results. Here, the time t _{0 at} which the air-conditioning estimation control is started, the time t at which the air-conditioning feedback control is started, and the time t ₂ at which a fixed time has elapsed since the start of the air-conditioning feedback control, are Changes in temperature and airflow are shown.
First, for the target location i, the estimated temperature is 27.9 [° C.] and the target temperature is 25.0 [° C.] at time t ₀ before execution of the air conditioning estimation control. By executing the control, the estimated temperature is changed to 25.0 [° C.] at time t, which is consistent with the initial target temperature.

For the air outlets A to D, at time t ₀ before the execution of the air conditioning estimation control, the air speed of the air is 1.00 [m / s] and the temperature is 26.0 [° C.], respectively. However, when the air-conditioning estimation control is executed, the wind speed of the blown air is 1.33 [m / s], 1.11 [m / s], and 1.13 [m / s, respectively, at time t. ], 1.05 [m / s], and temperatures changed to 23.4 [° C], 23.6 [° C], 25.2 [° C], and 25.5 [° C], respectively. It can be seen that the air conditioning estimation control is performed.

Furthermore, for the outlet A, at time t ₂ after the air conditioning feedback control execution, wind speed outlet air is changed to 0.85 [m / s], it is changing the temperature 23.9 [deg C] It can be seen that air-conditioning feedback control was performed for the outlet A.
As a result, for the target location j, the estimated temperature T _S is 24.9 [° C.] and the measured temperature T _M is 24.5 [° C.] at the time t after execution of the air conditioning estimation control. which error [Delta] T _SM had 0.4 [deg C] is, is executed conditioning feedback control using 24.9 equal to the estimated temperature T _S as the set temperature T _SP [deg C], in the subsequent time t ₂ The measured temperature is changed to 24.5 [° C.], and it can be seen that the measured temperature T _M is equal to the estimated temperature T _S by performing the air conditioning feedback control.

[Effect of the first embodiment]
Thus, in the present embodiment, after the air conditioning estimation control is started, the measured temperature T _M measured at the target location j in the air conditioned space 30 by the air conditioning feedback control determination unit 15C, and the reference temperature related to the target location j by comparison, to determine the switch to air-conditioning the feedback control to the target location j for correcting the temperature error [Delta] T _SM, when it is switching determination to the air conditioning feedback control, the air-conditioning instruction unit 15D, the estimated in a subject location j The air conditioning system 20 is instructed to start the air conditioning feedback control operation with the temperature T _S as the set temperature T _SP .

Thereby, the error which arises when air-conditioning control is performed with the operation amount obtained by the distributed system heat flow analysis method can be adjusted by the air-conditioning feedback control operation by the air-conditioning system 20.
Therefore, a comfortable air-conditioning environment set by the resident can be provided to the resident in the air-conditioned space 30.

Further, in the present embodiment, in the air conditioning feedback control determining section 15C, at the target location j by comparing the measured temperature change [Delta] T _MM and constant determination temperature range T _D of the target location j at a certain determination time Δt check the stable presence of the temperature field, after the stabilization of the temperature field in the target location j is confirmed. Thus to determine the switch to air-conditioning the feedback control for the target location j on the basis of the temperature error [Delta] T _SM, After confirming that the measured temperature change ΔT _MM is not transient and should be corrected by air conditioning feedback control for the target location j, switching to the air conditioning feedback control can be determined.
Thus, when measuring the temperature change [Delta] T _MM is of a transient is no longer determined to switch to the air conditioning feedback control, it is possible to avoid the execution of incorrect conditioning feedback control.

Further, in the present embodiment, after starting the air conditioning estimation control, the measured temperature T _M in the subject location j, the estimated temperature [Delta] T _SM is a reference temperature in a subject where j obtained by the thermal fluid analysis unit 15B, by comparing the allowable range T _L which is set in advance for the temperature error [Delta] T _SM, and determines switching to the air-conditioning feedback control for the target location j for correcting the temperature error [Delta] T _SM, to the air conditioning feedback control Since the air conditioning instruction unit 15D instructs the air conditioning system 20 to start executing the air conditioning feedback control operation with the estimated temperature T _S at the target location j as the set temperature T _SP . The switching to the air conditioning feedback control for the target location j can be accurately determined.

[Second Embodiment]
Next, with reference to FIG. 12, the air-conditioning control apparatus 10 concerning the 2nd Embodiment of this invention is demonstrated. FIG. 12 is a flowchart illustrating an air conditioning feedback control process according to the second embodiment.

In 1st Embodiment, when switching to air-conditioning feedback control was determined, the case where the stability of the temperature field of the object place j at the time was confirmed was demonstrated as an example. In the present embodiment, based on the slope a of the measured temperature T _{M at} the target location j, it is estimated whether or not the measured temperature T _M will converge within the allowable range T _L in the future. A case of determining switching will be described.

In this embodiment, the air conditioning feedback control determining section 15C includes a reference consisting of measured temperature measured retrospectively from the measured temperature T _M of the measured temperature T _M Toko eligible location j just past a certain determination time Δt in the target location j comparing the temperature, the function of calculating the measured temperature gradient a of the target location j from the measured temperature change [Delta] T _MM in a subject where j obtained, the reference of the measured temperature T _M which correspond to a preset temperature error [Delta] T _SM The slope A (ΔT _SM ) is compared with the measured temperature slope a, the measured temperature T _M at the target location j is equal to or higher than the estimated temperature T _{S at the} target location j, and the measured temperature slope a is the reference slope A (ΔT _SM ). In the above case, and when the measured temperature T _M at the target location j is lower than the estimated temperature T _{S at the} target location j and the measured temperature gradient a is less than the reference gradient −A (ΔT _SM ), Air conditioning feedback system And a function of determining to switch to.
In addition, about the other structure in the air-conditioning control apparatus 10 concerning this Embodiment, it is the same as that of 1st Embodiment, and it abbreviate | omits about detailed description here.

[Operation of Second Embodiment]
Next, an air conditioning feedback control operation will be described as an operation of the air conditioning control apparatus 10 according to the present embodiment with reference to FIG.
The arithmetic processing unit 15 of the air conditioning control device 10 starts the air conditioning feedback control process of FIG. 12 after the above-described air conditioning estimation control process of FIG. 7 is executed.

The air conditioning feedback control determination unit 15C first extracts the measured temperature T _M at the target location j from the measured temperature data 14C acquired by the data input unit 15A (step 200), and is obtained by the heat flow analysis processing unit 15B. The estimated temperature T _S at the target location j is extracted from the distribution data 14D (step 201), and the temperature error ΔT _SM (absolute value) between the estimated temperature T _{S at the} target location j and the actual measured temperature T _M at the current time t. ) Is calculated (step 202).

Next, the air conditioning feedback control determining section 15C, from the measured temperature change [Delta] T _MM indicating the change in measurement temperature T _M in the determination time Δt worth of prior to the current time t in the past, the measured temperature T _M in the determination time Δt min The inclination a = ΔT _MM / Δt is calculated (step 203), and the reference inclination A (ΔT _SM ) in the temperature error ΔT _SM is acquired based on a conversion table or a function equation preset in the storage unit 14 (step 203). 204).

FIG. 13 is an explanatory diagram showing the relationship between the temperature error and the reference inclination. Here, there is shown a relationship in which the reference slope A (ΔT _SM ) monotonously decreases as the temperature error ΔT _SM increases in each of the regions where the temperature error ΔT _SM is positive and negative. This relationship depends on the time constant of the temperature change determined from the size of the air-conditioned space 30 and the capacity of the air-conditioning equipment of the air-conditioning system 20, and may be acquired in advance through experiments or the like. This relationship may be expressed by a conversion table or a function expression.

Subsequently, the measured temperature T _M is compared with the estimated temperature T _S (step 205). If the measured temperature T _M is equal to or higher than the estimated temperature T _S (step 205: YES), the air conditioning feedback control determination unit 15C The inclination a is compared with the reference inclination A (ΔT _SM ) (step 206).
Here, when the measured temperature gradient a is equal to or greater than the reference gradient A (ΔT _SM ) (step 206: YES), it is predicted that the measured temperature T _{M at the} target location j will not converge within the allowable range T _L in the future. from the air conditioning feedback control determining section 15C, the temperature error [Delta] T _SM determines switching to air-conditioning the feedback control to the target location j for correcting a new set temperature estimated temperature T _S in the subject location j of the target location j the set temperature data 14G set as T _SP notifies the air-conditioning instruction unit 15D (step 207).

The air conditioning instruction unit 15D uses the communication I / F unit 11 to start the execution of the air conditioning feedback control operation using the estimated temperature T _S at the target location j as the set temperature T _SP based on the set temperature data 14G. The system is instructed (step 208), and the series of air conditioning feedback control processing is terminated.

On the other hand, if the measured temperature gradient a is smaller than the reference gradient A (ΔT _SM ) in step 206 (step 206: NO), the air conditioning feedback control determination unit 15C ends the series of air conditioning feedback control processes.

In step 205, if the measured temperature T _M is lower than the estimated temperature T _S (step 205: NO), the air conditioning feedback control determination unit 15C compares the measured temperature gradient a with the reference gradient −A (ΔT _SM ) ( Step 209).
Here, when the measured temperature gradient a is smaller than the reference gradient −A (ΔT _SM ) (step 209: YES), it is predicted that the measured temperature T _{M at the} target location j will deviate from the allowable range T _L in the future. from the air conditioning feedback control determining section 15C, the temperature error [Delta] T _SM determines switching to air-conditioning the feedback control to the target location j for correcting a new set temperature estimated temperature T _S in the subject location j of the target location j the set temperature data 14G set as T _SP notifies the air-conditioning instruction unit 15D (step 207).

The air conditioning instruction unit 15D uses the communication I / F unit 11 to start the execution of the air conditioning feedback control operation using the estimated temperature T _S at the target location j as the set temperature T _SP based on the set temperature data 14G. The system is instructed (step 208), and the series of air conditioning feedback control processing is terminated.

On the other hand, when the measured temperature gradient a is equal to or greater than the reference gradient −A (ΔT _SM ) in step 209 (step 209: NO), the air conditioning feedback control determination unit 15C ends the series of air conditioning feedback control processes.

FIG. 14 is an explanatory diagram illustrating an air conditioning feedback control operation according to the second embodiment. Here, the air conditioning estimation control is started at time t ₀ , the measured temperature T _{M at the} target location j gradually decreases from the temperature T ^t0 _M , and then decreases monotonously to the temperature T ^t _M at the current time t thereafter. The slope of this measured temperature is a.
In this case, although the measured temperature T _{M at} time t is equal to or higher than the estimated temperature T _S , the measured temperature gradient a is smaller than the reference gradient −A (ΔT _SM ), and the measured temperature T _M changes gently (in this case, decreases). Therefore, it can be predicted that the measured temperature T _M will converge within the allowable range T _L in the future.

FIG. 15 is another explanatory diagram illustrating the air-conditioning feedback control operation according to the second embodiment. In this case, although the measured temperature T _{M at} the time t is smaller than the estimated temperature T _S , the measured temperature gradient a is larger than the reference gradient −A (ΔT _SM ), and the measured temperature T _M changes relatively large (here, decreased). Therefore, it can be predicted that the measured temperature T _M will deviate from the allowable range T _{L in the} future.

[Effect of the second embodiment]
Thus, in the present embodiment, in the air conditioning feedback control determination unit 15C, and calculates a measured temperature gradient a of the target location j from the measured temperature change [Delta] T _MM eligible location j at a given judging time, which is set in advance Compared with the reference gradient A (ΔT _SM ) of the measured temperature T _M corresponding to the temperature error ΔT _SM , the measured temperature T _M is greater than or equal to the estimated temperature T _S and the measured temperature gradient a is greater than or equal to the reference gradient A (ΔT _SM ). If the measured temperature T _M is lower than the estimated temperature T _S and the measured temperature gradient a is smaller than the reference gradient −A (ΔT _SM ), the switching to the air conditioning feedback control for the target location j is determined. It is a thing.

Thereby, after starting the air-conditioning estimation control, without waiting until a time point at which the temperature field of the target location j is stable and the measured temperature T _M is converged or deviated within the allowable range T _L can be confirmed. Switching to the air conditioning feedback control for the target location j can be determined early. Therefore, if it is determined that the target location j is switched to the air conditioning feedback control, the air conditioning feedback control can be started in a short time after the start of the air conditioning estimation control. As a result, the temperature error at the target location j is reduced. It can be corrected early.

The waiting time t _W is compared (step 301).
If the elapsed time Δt is smaller than the standby time t _W (step 301: NO), the process returns to step 300.

On the other hand, when the elapsed time Δt is equal to or longer than the standby time t _W (step 301: YES), the air conditioning feedback control determination unit 15C determines switching to the air conditioning feedback control for the target location j, and the estimated temperature T _{S of the} target location j. Is set as the new set temperature T _SP at the target location j, and the air conditioning instruction unit 15D is notified of the set temperature data 14G (step 302).

The air conditioning instruction unit 15D starts the execution of the air conditioning feedback control operation using the estimated temperature T _S at the target location j as the set temperature T _SP based on the set temperature data 14G via the communication I / F unit 11.
