The color temperature sensor 9 of the slave device 2A is a temperature-sensitive element in which a temperature-sensitive color paint is applied to the temperature-sensitive portion, and has a temperature-color change characteristic in which the hue changes variously depending on the temperature sensitivity. As will be described later, it is provided at each predetermined location, and the temperature at the location can be detected by a change in hue to display a color. On the other hand, the color image sensor 10
For example, each of the color temperature sensors 9 provided with a solid-state color image pickup device in the image receiving portion and provided in a dispersed manner in the receiving area.
Detects the color-developing part in a predetermined order (imaging)
It is rotatably installed at a possible location. If necessary, two or more color image sensors 10 are provided. The color image sensor 10 is controlled by a dedicated controller in order to capture each color temperature sensor 9, and data obtained by detecting and hue-converting the hue (temperature signal) is detected. ) Is transmitted to the slave controller 8A.

FIG. 2 shows an outline of an air conditioning mode for the service area according to the embodiment of the present invention. The eight conditioned air outlets 11A to 11H in the use side unit 7A are
It is arranged at each of eight apexes with respect to the cubic area, and is provided so as to blow out conditioned air such as cold air from each apex toward the center of the area. It should be noted that the arrangement positions of the conditioned air outlets 11A to 11H may be selected at appropriate positions according to the form and situation of the holding area.

FIG. 3 is a perspective view showing the arrangement of the color temperature sensor 9 according to the embodiment of the present invention. With respect to the area of the cube, it is provided at each of the nodes consisting of the eight apexes a to i and the center of the area center point r, and the temperature at the installation portion is detected. It should be noted that the position of the color temperature sensor 9 may be selected by additionally increasing the number of nodes formed by the midpoint between the vertices indicated by a mark in FIG. Can be selected at any time according to the form and situation.

FIG. 4 shows a temperature detection procedure for the color temperature sensor 9. The temperature detection (sensing) by the color image sensor 10 performs center temperature and node temperature for each layer. The color image sensor 10 needs to be arranged in advance in a position where all the color temperature sensors 9 can be captured in each layer. In each layer, the color image sensor 10 is rotated two-dimensionally to perform sensing. , The range of movement of the color image sensor 10 between layers is made as small as possible and simplified. This is preferable because it leads to a smaller capacity of the controller of the color image sensor 10.

A flow diagram of the temperature sensing system is shown in FIG. A series of procedures for controlling the movement of the color image sensor 10 and causing the slave controllers 8A to 8C to capture the temperature data is shown in FIG. 5 (A), and a procedure for capturing the temperature data in FIG. 5 (B). The procedure is as shown in FIG. 5 (C).

FIG. 6 is a characteristic curve of the operating amount / demand amount relating to the main body 5 of the air conditioner 1, and FIG. 7 is a flow diagram of the air conditioning system according to the present invention. In FIG. ), (B), (C), and (D) are operation command flows,
The influence temperature flow, area temperature difference flow, and area operation command flow are shown respectively. The air conditioner body 5;
The outline of the operation control of the slave units 2A to 2C and the use side units 7A to 7C will be described below with reference to FIGS.

Regarding the operation command to the air conditioner main body 5, a value obtained by multiplying the operation amount obtained based on the operation amount-request amount characteristic curve diagram previously obtained at the time of design by a coefficient is obtained, and this value is obtained. Given to 5. In the operation amount-request amount characteristic curve diagram, the request amount means the total value of the previous (current) operation amount and the sum of the area change amounts in each of the use side units 7A to 7C. This operation command is output from the main controller 6 to operate the heat source side unit.

On the other hand, regarding the area operation command to each of the use side units 7A to 7C, the area change amount and the previous (current)
The area command value, which is the sum of the area command values, is calculated, and this value is given to each of the use side units 7A to 7C.
The area change amount is determined by the temperature / heat quantity characteristic in consideration of the area temperature difference and the affected temperature. In this case, the area temperature difference is represented by the difference between the area temperature indicated by the average value of the center temperature and the average node temperature and the set temperature. By the way, regarding the influence temperature, the direction and the value of the influence can be obtained by recognizing the center temperature and the node temperature of the holding area (area). As a pattern determination method at this time, if some node temperatures are different from other nodes and there is no difference between the center temperature and most node temperatures, it is determined that there is an influence, and the temperature difference between each node temperature is determined. If there is almost no, it is appropriate to judge that there is no effect.

Therefore, it is preferable to use a neural network for the temperature determining portion based on the affected temperature and the temperature signal from the color image sensor 10. The neural network is formed as a software on a microcomputer and is responsible only for pattern recognition.
Before and after processing is performed by a microcomputer. As a result, problems such as numerical value handling and temporary storage are easily solved. In pattern recognition, the direction of the affected temperature is determined by
The temperature difference is pattern-recognized stepwise, the result is patterned, and the direction is determined by the result of the pattern recognition finally.

Since the temperature determination by the color image sensor 10 can be performed almost in the same manner as the character reading pattern recognition, there is no problem in using the neural network. It has been known that the use of neural networks in the recent control field has a great effect on learning control, and even if teacher patterns can be properly determined, nothing is needed thereafter.
