An outline of the individual difference learning adaptive control in the adaptive control system (4) which is the basic principle of the air conditioning control will be described. First, in order to apply the expected average declared PMV to this control, some of the formulas adopted by the fanger are replaced with the relations shown in the following formula. The formula for radiant heat transfer is R = hr ・ (Tc1-Tr) …… (1) R: Heat radiation per unit area hr: Radiant heat transfer coefficient Tc1: Clothing temperature Tr: Radiant temperature, 18.0 ℃ <Tr <30.0 ℃ Become. The equation for convection heat transfer is hc = hcn + hcf = constant + κ · V ^0.67 (2) hc: convection heat transfer coefficient hcn: forced convection heat transfer coefficient hcf: natural convection heat transfer coefficient κ: constant V: airflow velocity and Become. From the above equations (1) and (2), the following equation in which the thermal sensation index Vhat is developed in an explicit form is derived. Vhat = θhat0 + θhat1 · Pv + θhat2 · Ta + θhat3 · Tr + θhat4 · V ^2/3 + θhat5 · Pv · V ^2/3 + θhat6 · Ta · V ^2/3 (3) θhat0 ~ θhat6: Parameter Ta: Room temperature Pv: Room vapor pressure ( Indoor humidity) Further, if the air velocity V is constant (V = constant) and the radiation temperature Tr is equal to the wall surface temperature Tw (Tr = Tw),
The following linearized equation is obtained from equation (3). Vhat = Chat0 + Chat1, Pv + Chat2, Ta + Chat3, Tw (4) Chat0-Chat3: Parameters Then, the above expression (3) or (4) is used as a thermal sensation model, that is, a user model, and is declared by the user (12). By tuning the parameters θhat0 to θhat6 or Chat0 to Chat3 according to the thermal sensation, the thermal sensation of each user (12) is learned and the thermal sensation index Vhat, which is the predicted thermal sensation, is matched with the thermal sensation. By doing so, the optimum goal for the user (12) can be determined.

On the other hand, if a simple HVAC system (1) (see FIG. 2) in which the heat input q is proportional to the compressor frequency is modeled from the conservation equation of energy and vapor pressure, the following equation of state can be derived. it can. X = A * x + b * q (5) In this equation (5), the state variable x , the heat constant A indicating the heat balance of the room (11), and the indoor heat exchanger of the air conditioner (2) The thermal constant b is as follows.

[0017]

[Formula 1] Tm: Indoor heat exchanger temperature To: Outdoor temperature Po: Outdoor vapor pressure (outdoor humidity) When the state variable x is used, the above thermal sensation index Vhat is nothing but an output error of the HVAC system (1), It becomes as follows. Vhat = y−r (7) y = c · x (8) where y is a term related to the above-mentioned state variable (indoor / outdoor temperature difference and humidity difference), and r is an outdoor condition. It is a term related to, and is as follows. r = -Chat0-Chat2 * Po- (Chat1 + Chat3) * To (9) c = [0, Chat2, Chat3, Chat1] (10) Therefore, from heat input q (compressor frequency) to thermal sensation index Vha

On the other hand, as a learning method for the parameters θhat0 to θhat6 or Chat0 to Chat3, the constrained recursive least squares method is used. This converges θ ^* to a parameter vector that is guaranteed to exist in the closed and convex subspace C (room) in the m-dimensional space Rm. In ^{this, θ * (n) = φ} T (n) · θ a ^* algorithm to converge the parameter vector theta ^* inside the subspace C is equal to or less than the above recurrence formula. (For details, see Grah
“Adaptive Fil” by am C. Goodwin and Kwai Sang Sin

ood Cliffs, New Jersey, 1984.) e (n) = V ^* (n) −φ ^T (n) ・θ hat (n) …… (12) K (n) = P (n-1) ・φ ( n) / {1 + φ ^T (n) ・ P (n-1) ・φ (n)} …… (13) θ hat (n) ＝ θ hat (n-1) ＋ K (n) ・ e (n ) ...... (14) P (n ) = {I- K (n) · φ T (n)} · P (n-1) ...... (15) Therefore, now, the use of PID control to the controller, transfer The function is Gc (s) = {K1 · (s + K2) · (s + K3)} / s (16). The heat input q (compressor frequency) is added to this transfer function.
Is an open-loop transfer function from the thermal sensation index Vhat to (11)
By multiplying the equation, the closed loop transfer function of the entire system can be obtained by the following equation.

[0020]

[Formula 3] As a result, the control gain is obtained. Based on the above principles, the parameters θhat0 to θha are calculated from the user (12) declaration.
While learning t6 or Chat0 to Chat3, from the learned parameters Chat0 to Chat3, the indoor temperature Ta around the user (12), the indoor humidity Pv, and the radiation temperature Tr, the thermal sensation index V is obtained.
The hat is calculated, and P is set so that the thermal sensation index Vhat becomes 0.
The frequency of the compressor is changed by the ID control. And
After 20 minutes have passed, the parameters Chat0 to Chat3 are learned again. This control is repeated (3 or 4 times) to satisfy the comfort of each user (12).

Therefore, the adaptive control system (4), based on the above-mentioned principle, has a parameter evaluation section (41), a parameter storage section (42), a thermal sensation index calculation section (43), and a hot / cold state. It is composed of a feeling index determination unit (44). The parameter evaluation unit (4
1) is a parameter setting for receiving the user's (12) true / cold sensation signal from the declaration input section (61) and calculating the parameters Chat0 to Chat3 by the algorithm based on the above equations (12) to (15). Constitutes a means. That is, the parameter evaluation unit (4
1) compares the thermal sensation declared by the user (12) with the thermal sensation index Vhat which is the predicted thermal sensation, and the thermal sensation difference between the thermal sensation and the expected thermal sensation is calculated. At least one of the parameters Chat0 to Chat3 is evaluated and changed so as to become zero. Particularly, as a feature of the present invention, the parameters Chat0 to Chat3 are calculated in consideration of the panel temperature of the radiation panel (7). The parameter storage unit (42) is configured to store the parameters Chat0 to Chat3 calculated by the parameter evaluation unit (41). The thermal sensation index calculation unit (43) receives the parameter signals of the parameters Chat0 to Chat3 stored in the parameter storage unit (42), and also detects the room temperature and the panel temperature from the environmental state detection unit (13). Receiving the detection signal,
A thermal sensation index calculation means for calculating the thermal sensation index Vhat is configured. That is, the thermal sensation index calculation unit (43) calculates an index indicating whether the current room is hot or cold, and serves as the user model. Furthermore, the thermal sensation index determination unit (44) receives the thermal sensation signal of the thermal sensation index Vhat calculated by the thermal sensation index calculation unit (43), and whether the thermal sensation index Vhat becomes 0. Whether or not the change amount ΔVhat, which is a differential value of the thermal sensation index Vhat, has become 0 (the thermal sensation index Vhat
Is stable to 0), that is, whether or not the room is in a comfortable state is determined, and a control value determination means for calculating a control value that minimizes power consumption is configured as a feature of the present invention. ing. The PID controller (51) receives the determination signal of the thermal sensation index determination unit (44), and the PID controller (51) calculates the control gain from the equation (17) to calculate the thermal sensation index Vhat. The operating frequency of the compressor and the radiation panel (7) are PID-controlled so that 0 becomes 0.

Therefore, the radiation panel which is a feature of the present invention
The basic principle of control in (7) and control of minimum power consumption will be explained. First, in equation (4) above, the wall temperature Tw
Is originally a radiation temperature Tr as shown in the equation (3), and this radiation temperature Tr is developed as the following equation by the radiation temperature Tr1 from the environment and the panel temperature Tr2. Tr = A1 · Tr1 + A2 · Tr2 + A3 (18) A1 to A3: Constants determined by form factor And each parameter Chat0 to Chat3 constituting the thermal sensation index Vhat is a compressor frequency q (compressor input). As a result, the thermal sensation index Vhat can be considered as a two-variable function of the compressor frequency q and the panel temperature Tr2 as shown in the following equation. Vhat = Vhat (q, Tr2) (19) On the other hand, the power consumption P is the power consumption P1 of the air conditioner (2).
And the power consumption P2 of the radiation panel (7) is given by the following equation. P = P1 + P2 (20) Then, the power consumption P1 of the air conditioner (2) is a function of the compressor frequency and the air velocity, and the power consumption P2 of the radiation panel (7) is the panel temperature Tr2 (radiation As a function of temperature, it becomes as shown in the following equation. P1 = k1 · q + k2 · V 3 ...... (21) P2 = Tr2 / k3 ...... (22) k1~k3: Constant V: air velocity (constant) power consumption P from above (20) - (22) equation, As shown in the following equation, it can be considered as a two-variable function of the compressor frequency q and the panel temperature Tr2. P = P (q, Tr2) (23) From the above, the compressor frequency q and the panel temperature T which are functions on the line that satisfy the thermal sensation index Vhat = 0.
A combination that minimizes the power consumption P can be considered from the combination with r2. Therefore, mathematically,
As shown in the following equation, the extremum due to the introduction of Hamiltonian,
That is, it can be obtained as the solution of the minimum value. H = P (q, Tr2) + λ1 · X ( x , q) + λ2 · Vhat (q, Tr2) …… (24) δP / δq + λ1 (δX / δq) + λ2 (δVhat / δq) = 0 …… (25) δP / δTr2 + λ1 (δX / δTr2) + λ2 (δVhat / δTr2) = 0 ...... (26) δP / δ x + λ1 (δX / δ x) + λ2 (δVhat / δ x) = 0 ...... (27) and, of these From equations (25) to (27), X = 0, Vhat =
0, P = min can be obtained. Therefore, as described above, in the parameter determination unit (41), the parameters Chat0 to Cha in consideration of the panel temperature Tr2 are calculated from the equation (19).
t3 is calculated, and in the thermal sensation index determination unit (44), the compressor frequency and the control value of the radiation panel (7) are calculated from the equations (25) to (27).

After evaluating hat0 to Chat3, the process proceeds to step ST4, and the thermal sensation index calculation unit (43) calculates the thermal sensation index Vhat based on the equation (4). After that, the process proceeds to step ST5, and the panel temperature Tr2 of the radiation panel (7) is input from the environmental condition detection part (13), while the operating frequency of the compressor is commanded by the PID controller (51) in step ST6. Next, in step ST7, the environmental condition detection unit (13) detects the indoor temperature and the like, and the thermal sensation index calculation unit (43) again causes the thermal sensation index to be calculated based on the detected environmental physical quantity such as the indoor temperature. Vhat
Is calculated based on equation (4). Then, step ST

Then, it is determined whether or not the change amount ΔVhat = 0 of the thermal sensation index Vhat, and the process proceeds to step ST10 until Vhat = 0 and the change amount ΔVhat = 0, and the PID controller (51) causes the operating frequency of the compressor. PID control is performed and the process returns to step ST6. On the other hand, when the thermal sensation index Vhat = 0 and the variation ΔVhat = 0 in step ST9, the determination is YES, the process proceeds to step ST11, and the power consumption P is calculated in the thermal sensation index determination unit (44). Is determined to be the minimum (P = min), the process proceeds to step ST12 until it is minimized, the radiation panel (7) is PID controlled, and the process returns to step ST6.

The parameters Chat0 to Chat3 are changed and set on the basis of the algorithms of the above formulas (12) to (15) so that the index Vhat matches the temperature sensation. Then, this set parameter C

The PID controller (51) PID-controls the operating frequency of the compressor so that the new thermal sensation index Vhat becomes zero, and the radiation panel (7) is PID so as to minimize the power consumption P. Have control. After that, in step ST11, when the power consumption P becomes minimum, the determination becomes YES, the process proceeds to step ST13, it is determined whether or not the parameters Chat0 to Chat3 are equal to or less than a predetermined value ε, and the above is performed until the predetermined value ε is reached. While returning to step ST2,
When the predetermined value ε is reached, the process proceeds to step ST14 and the parameter C
The hat0 to Chat3 are calculated and the above operation is repeated. That is, the learning control of the parameters Chat0 to Chat3 is performed every 20 minutes, and the thermal sensation index V that is the predicted thermal sensation is obtained.
The hat will match the true temperature sensation of the user (12) after three or four times of learning, and thereafter, the air conditioning control matching the user (12) will be performed based on this thermal sensation index Vhat. Become.

It can be considered as a two-variable function with Pv (indoor vapor pressure). Vhat = Vhat (q, Pv) (28) On the other hand, the power consumption P is the power consumption P1 of the air conditioner (2).
And the power consumption P3 of the humidifier / dehumidifier (8) are given by the following equation. P = P1 + P3 (29) Then, the power consumption P1 of the air conditioner (2) is a function of the compressor frequency and the airflow speed, and the power consumption P3 of the humidifier / dehumidifier (8) is the indoor humidity Pv. It becomes a function, and the power consumption P can be considered as a two-variable function of the compressor frequency q and the indoor humidity Pv as shown in the following equation. P = P (q, Pv) (30) From the above, the combination of the compressor frequency q and the indoor humidity Pv, which is a linear function that satisfies the thermal sensation index Vhat = 0. A combination that minimizes the power consumption P can be considered from the inside. Therefore, mathematically, Vhat = 0 and P = min can be obtained as a solution of the extreme value, that is, the minimum value by introducing the Hamiltonian, as shown in the following equation. H = P (q, Pv) + λ1 · X ( x , q) + λ2 · Vhat (q, Pv) (31) Therefore, as described above, in the parameter determination unit (41), the equation (28) is used. Then, the parameters Chat0 to Chat3 in consideration of the indoor humidity Pv are calculated, and in the thermal sensation index determination unit (44), the compressor frequency and the control value of the humidifier / dehumidifier (8) are calculated based on (31). I am trying to calculate. Other configurations are similar to those of the previous embodiment.

Next, the control operation of the HVAC system (1) will be described based on the control flow of FIG. The control of this embodiment is performed in the same manner as the previous embodiment shown in FIG.
First, when the control operation of the air conditioner (2) is started, the initial values of the parameters Chat0 to Chat3 are set, and then the true thermal sensation input from the user (12) from the declaration input unit (61) is applied to the parameter evaluation unit. Is input to (see steps ST1 and ST2).
Then, the parameter evaluation unit (41) causes the parameter Chat0
After evaluating ~ Chat3, the thermal sensation index calculation unit (43) calculates the thermal sensation index Vhat based on the equation (4) (see steps ST3 and 4), and then drives the humidifier / dehumidifier (8). Yes (see step ST21). On the other hand, the operating frequency of the compressor is commanded by the PID controller (51) (see step ST6). Then, based on the environmental physical quantities such as the indoor temperature and the indoor humidity detected by the environmental condition detection unit (13), the thermal sensation index calculation unit (4
3) calculates the thermal sensation index Vhat based on equation (4). Subsequently, the thermal sensation index determination unit (44) causes the thermal sensation index Vhat = 0.
And whether or not the variation amount ΔVhat = 0 of the thermal sensation index Vhat is determined, and the PID controller (51) sets the operating frequency of the compressor to P until the variation amount Vhat = 0 and the variation amount ΔVhat = 0.
ID control is performed (see steps ST6 and ST10).

On the other hand, when the thermal sensation index Vhat = 0 and the variation ΔVhat = 0, the thermal sensation index determination unit (44) determines whether or not the power consumption P is minimum (P = min). , PID control the humidifier (8) until it becomes minimum (step
See ST22). That is, the PID controller (51) outputs a control signal to the air conditioner (2) and the humidifier / dehumidifier (8) so that the thermal sensation index Vhat becomes zero (comfort state), and the operating frequency of the compressor is changed. In addition to PID control, the humidifier / dehumidifier (8) is PID controlled so that the power consumption P is minimized. After that, when the power consumption P becomes the minimum, the parameter Cha
It is determined whether or not t0 to Chat3 is less than or equal to a predetermined value ε, and the process returns to step ST2 until it reaches the predetermined value ε, while when it reaches the predetermined value ε, the process proceeds to step ST14 to calculate the parameters Chat0 to Chat3 and perform the above-described operation. Will be repeated.

Therefore, according to this embodiment, the humidifier / dehumidifier (8)
Since the indoor humidity is used to calculate the thermal sensation index to control not only the air conditioner (2) but also the humidifier / dehumidifier (8), users (12 )
It can also correspond to. For example, as shown in FIG. 8, when learning control is performed on the parameters Chat0 to Chat3, the parameter Chat1 may have a large value. This parameter Chat1 is the indoor humidity as shown in equation (4).
This is a parameter related to Pv, and even the user (12) who is sensitive to the indoor humidity Pv can actively perform air conditioning control, and can improve comfort. In addition, since the minimum power consumption is calculated, it is possible to perform energy-saving operation that corresponds to each user (12) while considering the indoor humidity, and to perform inexpensive and comfortable air conditioning operation. It can be carried out.

In each of the embodiments, the thermal sensation index determining unit (44) uses Hamiltonian, but in the present invention, Lagrangian or the like may be used. Further, in the first embodiment, the radiant heat supply means may use a cold water panel instead of the radiant panel (7). In addition, the above-mentioned declaration input section
(61) is not limited to the remote controller and may be a dedicated input means. The adaptive control system (4) is not limited to the embodiment, and the air conditioner (2) is not limited to the wall-mounted type, of course.
