Abstract: An environment control system includes: a second storage unit storing a fluid model inside a space; a second communication unit configured to obtain temperature information inside the space and an operation state of an air conditioner provided in the space; an estimation unit configured to estimate a three-dimensional environmental distribution inside the space, based on the fluid model stored in the second storage unit, the obtained fluid parameter information, and the obtained operation state; and a control unit configured to control the air conditioner, based on the estimated three-dimensional environmental distribution.

Abstract: An environment estimation device includes a determination unit and a correction unit. The determination unit changes, by varying a boundary variable from an initial value, first environmental information in a specific region of an estimated three-dimensional environmental distribution, and determines, as an object boundary variable, the boundary variable at a time when a difference between the first environmental information and second environmental information in the specific region included in obtained environmental information inside a space is within a predetermined range. The correction unit corrects a numerical fluid dynamic model, by fixing a variation parameter of the numerical fluid dynamic model at the determined object boundary variable.
