Abstract

An air conditioning control system transmits control content to an air conditioning apparatus and adjusts an environmental state in a target space. The air conditioning control system includes an acquisition unit and a control content determination unit. The acquisition unit acquires a target environmental state. The control content determination unit has a learning model having an input and an output. The input is the target environmental state. The output is determined control content. The determined control content is the control content to be transmitted to the air conditioning apparatus in order to bring the target space closer to the target environmental state. The learning model has been trained by using, as a learning dataset, learning control content and a learning environmental state. The learning control content is the control content for the air conditioning apparatus. The learning environmental state is the environmental state in the target space.

Claims (47)

1. An air conditioning control system configured to transmit determined control content to an air conditioning apparatus and adjust an environmental state in a target space of an air conditioning operation performed by the air conditioning apparatus, the air conditioning control system comprising:

a processor; and

a storage,

the processor being configured to

acquire a target environmental state to which the environmental state is to be adjusted, the target environmental state being represented as image data created based on a simulation of the environmental state in the target space using current control content of the air conditioning apparatus; and

use a learning model to create the determined control content based on the image data, the learning model having an input and an output, the input being the image data and the output being the determined control content, and

transmit the determined control content to the air conditioning apparatus in order to bring the target space to the target environmental state,

the learning model having been trained by using, as a learning dataset, learning control content and a learning environmental state, the learning environmental state being created by simulating the environmental state in the target space based on the learning control content, the learning environmental state being represented as learning image data.

2. The air conditioning control system according to claim 1 , wherein

the target environmental state is the environmental state to be achieved in a partial space, the partial space being a part of the target space,

the determined control content is the control content to be transmitted to the air conditioning apparatus in order to bring the partial space closer to the target environmental state, and

the learning environmental state relates to the partial space.

3. The air conditioning control system according to claim 2 , wherein

the partial space is a predetermined three-dimensional region in the target space.

4. The air conditioning control system according to claim 2 , wherein

the partial space is a predetermined two-dimensional region in the target space.

5. The air conditioning control system according to claim 2 , wherein

the learning environmental state is an output result of one or more simulations performed by using the learning control content as an input.

6. The air conditioning control system according to claim 2 , wherein

the determined control content is an air conditioning control parameter including a value relating to at least one of temperature, humidity, air flow direction, air volume, and air velocity.

7. The air conditioning control system according to claim 2 , wherein

the environmental state is an environmental parameter at one or more locations in the target space, and

the environmental parameter includes a value relating to at least one of temperature, humidity, air flow direction, air volume, and air velocity.

8. The air conditioning control system according to claim 2 , wherein

the target environmental state is determined based on a desire relating to the environmental state input via a user interface.

9. The air conditioning control system according to claim 2 , wherein the learning dataset further includes space layout information, the space layout information being information on an object in the target space.

10. The air conditioning control system according to claim 9 , wherein

the space layout information includes, as the information on the object in the target space, information regarding an amount of heat.

11. The air conditioning control system according to claim 2 , wherein

the learning dataset further includes arrangement information of one or more air outlets of one or more air conditioning apparatuses.

12. The air conditioning control system according to claim 1 , wherein

the learning environmental state is created by performing a plurality of simulations performed by using the learning control content.

13. The air conditioning control system according to claim 1 , wherein

the determined control content is an air conditioning control parameter including a value relating to at least one of temperature, humidity, air flow direction, air volume, and air velocity.

14. The air conditioning control system according to claim 1 , wherein

the environmental state is an environmental parameter at one or more locations in the target space, and

the environmental parameter includes a value relating to at least one of temperature, humidity, air flow direction, air volume, and air velocity.

15. The air conditioning control system according to claim 1 , wherein

the target environmental state is determined based on the simulation and a desire relating to the environmental state input via a user interface.

16. The air conditioning control system according to claim 1 , wherein

the learning dataset further includes space layout information, the space layout information being information on an object in the target space.

17. The air conditioning control system according to claim 16 , wherein

the space layout information includes, as the information on the object in the target space, information regarding an amount of heat.

18. The air conditioning control system according to claim 1 , wherein

the learning dataset further includes arrangement information of one or more air outlets of one or more air conditioning apparatuses.

19. The air conditioning control system according to claim 1 , wherein

the image data represents an environmental distribution diagram of an environmental parameter, the environmental parameter being a value related to at least one of temperature, humidity, air flow direction, air volume, or air velocity in the target space.
