The present invention relates to an air-conditioning control system that creates an air-conditioned environment in which people feel comfortable.

As the background art of the present invention, for example, in an air conditioning environment monitoring system, an indoor airflow simulation program first acquires boundary condition data such as the amount of heat generated in and out of the room and the amount of heat generated in and out of the room, and the shape of the room. The indoor space is divided into meshes based on the data and the space grid data that divides the fluid in the area to be analyzed at appropriate intervals, and the simulation is performed from the obtained boundary condition data, and the temperature distribution and airflow in the room are calculated for each mesh. There is a technology that enables automatic air conditioning control operation to reflect the simulation results of wind speed, air temperature, and sensible temperature arranged on spatial grid data by calculating velocity distribution (see Patent Document 1, for example).

In the air-conditioning control system, simulation software is used to obtain the temperature distribution in the air-conditioned room, and for each area, a plurality of countermeasure parameters that define the control to be performed when a problem occurs are registered. If there is a problem, a simulation is performed with additional countermeasure parameters for that area to determine the suitability of the countermeasure. If the problem cannot be solved, the next countermeasure parameter is added and the simulation is repeated. If the problem cannot be solved even after sending instruction information and adding all countermeasure parameters, there is a technique for notifying that effect (see, for example, Patent Document 2).

Further, in the information processing system, the analysis unit performs a simulation using a simulation model including a space model that is an analysis model of the room and an object model that is an analysis model of objects existing inside the room, There is a technique in which at least one of one or more control parameters for controlling equipment is determined, and a central monitoring device controls air conditioning equipment based on the determined control parameter (see Patent Document 3, for example).
