Therefore, the set temperature of the air conditioner is also controlled to fall within the range of 18°C to 25°C.

However, in conventional air conditioning control systems, the temperature is individually controlled within the range of 18℃ to 25℃ for each room.
They may enter a room where the temperature is 0°C, or enter a room where the room temperature is 20°C from outside where the outside temperature is 5°C or less in winter. Frequently experiencing sudden temperature changes like this disrupts a person's body temperature regulation function and causes them to become unwell. For this reason, there is a need for appropriate air conditioning control according to the location of each air conditioner in a building based on the outside temperature.

[Objective of the Invention] An object of the present invention is to provide an air conditioning control system that can appropriately control air conditioners installed in each room based on outside temperature and according to the location of each air conditioner in a building. It's about doing.

[Summary of the Invention] In order to achieve the above object, the present invention has a room temperature sensor provided in each room to detect the temperature of each room, and a plurality of sensors that operate to make the room temperature match a target temperature. an air conditioner, an outside temperature detection means for detecting the outside temperature, a signal transmission means for connecting each air conditioner and the outside temperature detection means, and a target temperature of each air conditioner for each air conditioner based on the detected outside temperature. The gist is to have a control means that is determined separately depending on the location of the machine in the building.

[Effects of the Invention] According to the present invention, it becomes possible to optimally control air conditioning according to the outside temperature and according to the location of each air conditioner in a building. As a result, it is possible to eliminate problems caused by air conditioning, such as people becoming unwell due to sudden temperature changes, and it is also possible to perform optimal air conditioning according to the usage status of the room.

[Embodiment of the Invention] FIG. 1 shows an air conditioning control system in an embodiment of the present invention.

This embodiment includes a bus line controller, an outside temperature sensor 5 connected to the bus line controller via an interface (1/F) 3e, and an interface 3a, which is also connected to the bus line controller.
Three air conditioners I! connected via 3b and 3c! (hereinafter referred to as air conditioner) 7a.

7b, 7C, and each air conditioner 7a, 7b, 7C is provided with a room temperature sensor 9a, 9b, 9c.

The pass line 1 includes an outside temperature detection device 5, each air conditioner 7a,
A medium for transmitting outside temperature data, an outside temperature data request command, etc. between 7b and 7c is a coaxial cable, metallic bare wire, shielded twisted pair wire, or the like, as appropriate.

As shown in FIG. 2, the outside temperature detection device 5 includes a reamister 5a that detects temperature changes by resistance changes, an Al1) converter 5b that digitizes the detected outside temperature, and a digital outside temperature data. It is equipped with a microcomputer 5C that takes in outside temperature data and controls the output of this outside temperature data to the pass line 1 by baseband transmission. A fixed time report request switch 5d and an outside temperature request switch 5e are connected to the microcomputer 5C. The fixed-time report request switch 5d transmits outside temperature data to each air conditioner 9a, 9b, and 9c at regular intervals in the on state, and the outside temperature request switch 5e transmits outside temperature data from any of the air conditioners 7a to 7c. When the request command is transmitted, it is received and the outside temperature data is transmitted to the air conditioners 78 to 7c that have made the request. The outdoor temperature detection device 5 is installed at a height of 1 to 2 tons above the ground outdoors.
A location outside of a room where there are a lot of people and people going out is preferable.

As shown in Fig. 3, the air conditioner 7a is placed in room A (for example, the living room), which is closest to the entrance and has the most access, the air conditioner 7b is placed in room B, which is the next closest to the entrance, and the air conditioner 7C is installed in the room farthest from the entrance. They are installed in each of the few C rooms (for example, the inner space).

Further, each of the air conditioners 78 to 7c is connected to a room temperature sensor 9a, 9b, 9c that detects the temperature of each room, and an outside temperature reference switch 11a, 11b, 11c.

The outside temperature reference switches 11a to 11C transmit an outside temperature data request command to the outside temperature detection device 5 according to a program stored in advance in the air conditioner in the on state, and take in the transmitted outside temperature data to determine the outside temperature. Used to perform air conditioning control with reference to

The interfaces 38 to 3C and 3e monitor the bus line controllers and input outside temperature data or outside temperature request commands to the air conditioners 78 to 7C or the outside temperature detection device 5.

This embodiment has the above configuration, and its operation will be explained below.

In this embodiment, outside temperature data and outside temperature request commands are sent to each air tip 7 via a bus line controller using the C8MA/CD method.
8 to 7C and the outside temperature detection device 5.

The outside air temperature is detected by the outside air temperature detection device 5, and the detected outside air temperature is taken into the microcomputer 5c at predetermined intervals. Further, the temperature of each room (1 m) is detected by the Ω sensors 19a to 9C for each room, and is supplied to the air conditioners 78 to 7C.

FIG. 4 shows the outside temperature data output process executed at the outside temperature detection station 5.

In step 201, it is monitored whether the fixed-time report request switch 5d is on. If there is a fixed time report request (on state), the process advances to step 203, and all air conditioners 9a
, 9b and 9c, outside temperature data is transmitted via path line 1. On the other hand, if there is no fixed-time report request, the process advances to the next step 205.

In step 205, reception of outside temperature request commands transmitted from each air conditioner 78 to 7C is monitored. If there is no outside temperature request command, the outside temperature f - evening will not be output.
Proceed to step 209. Further, when the outside temperature request command is received, the process proceeds to the next step 207, and the outside temperature data is output to the air conditioners 78 to 7C that are the sources of the outside temperature request.

In step 209, new outside temperature data detected by the thermistor 5a is taken in, the outside temperature data is updated, and the process returns to the first step 201. From then on, step 201~
The process of 209 is repeatedly executed.

When the outside temperature detection device 5 executes outside temperature data output processing in this way, each air conditioner 7a, 7
b, 7c, the air conditioner control process shown in FIG. 5 is executed.

In FIG. 5, in the first step 301, the ON states of the outside temperature reference switches 113 to 11c are monitored. If any of the outside temperature reference switches 11a to 11C is turned on, the process advances to the next step 303.

In step 303, input of outside temperature data is monitored, and if outside temperature data is present, the process proceeds to step 305, where outside temperature data input processing is executed.

Then, in the next step 307, the air conditioner control of each room (entering room, B room, G room) with reference to the outside temperature is executed as follows.

In other words, the room closest to the entrance where many people come in and out is controlled to be 5°C lower than the outside temperature when cooling, and 5°C higher when heating.

Further, the air conditioner 7b in room B is controlled so that the temperature is further 5° C. lower during cooling and 5° C. higher during heating than the temperature when entering the room.

The air conditioner 7C in room G is controlled by 1lJt[l so that the temperature is roughly 5°C lower during cooling and further 5°C higher during heating than the temperature in room B.

However, the temperature in each room is within the appropriate temperature range of 18℃ to 25℃.
When the temperature is within the range of , the temperature is controlled within the range of .

On the other hand, in the processing of steps 301 and 303, if all of the outside temperature reference switches 118 to 11c are off and no outside temperature data is input, the process advances to step 309;
Air conditioner control is performed only based on the temperature of each room detected by the room temperature sensor 11 without referring to outside temperature data.

In this way, in this embodiment, it is possible to easily control the air conditioning by sequentially setting a temperature difference of 5 degrees Celsius from Room I-B, which is close to the entrance and has many people going in and out, to Room G, which is farthest from the entrance and has few people going in and out. . As a result, people who enter the room from outside do not have to worry about getting sick because there is no sudden change in temperature.

Furthermore, since unnecessary air conditioning control can be avoided, it is extremely advantageous in terms of energy saving.

FIG. 6 shows an air conditioning control system in another embodiment of the present invention. Incidentally, the same components as those in the above embodiment are given the same reference numerals, and the explanation thereof will be omitted.

This embodiment includes an outside temperature detection device 5 and four air conditioners 7a, 7.
b, 7c, and 7d are centrally managed by a C central controller 13 via a bus line controller.

As shown in FIG. 7, the air conditioners 7a to 7d are installed in order from room DI, which is closest to the entrance and has the most people coming in and out, to room G, which is farthest from the entrance and has the least amount of people going in and out.

The central controller 13 is mainly composed of a microcomputer, and monitors and controls the air conditioning status of each room (room D, room E, room F, and room G). Therefore, the temperature of each room detected by the room sensors 9a to 9d and the outside temperature detected by the outside temperature detection device 5 are displayed on the panel surface of the central controller 13, as shown in FIG. It is equipped with a temperature display section for changing the air conditioning operation status of each room (for example, cold/warm switching, operation switching, J rabbit...adjustment 9-hour setting, room temperature adjustment, etc.), and an outside temperature reference switch 11c. It is provided.

Next, the operation will be described. When the outside temperature reference switch 110 of the central controller 13 is turned on, outside temperature data is transmitted from the outside temperature detection device 5 via the bus line in response. On the other hand, this central controller 13 is supplied with the room temperature data of each air conditioner 7a to 7 (from 1 to room G at all times, and the above outside temperature data and the room temperature of each room).
The target temperature for each room is calculated from the data and the calculation result c5 is outputted to each air conditioner 7a to 7d via the bus line controller.

Each air conditioner 7a to 7d receives the target temperature and controls the temperature of each room to match the target temperature. ! However, Room D4, which is closest to the population and has the most people coming in and out, is controlled to ±5℃ from the outside temperature (G indicates heating, - does not indicate cooling), and the rooms farthest from the population are the following: The temperature is controlled by providing a 1η difference in temperature of ±5° C. up to the G room with the lowest temperature. However, when the temperature of each chamber is within the appropriate temperature range of 18° C. to 25° C., the temperature is controlled within that temperature range.

Then, this centralized control [1-La 13 includes each air conditioner 7]
The temperature of each room supplied from 8 to 7d is displayed on the temperature display section.

As described above, in this embodiment, the air conditioners 78 to 7d in each room can be easily centrally controlled by the central controller 13, and therefore, for example, the air conditioners 78 to 7d in each room can be centrally controlled. It becomes possible to monitor the air conditioning in each hospital room and perform detailed air conditioning control.
