Document Type and Number:
WIPO Patent Application WO/2021/256824
Kind Code:
A1
Abstract:
The present invention relates to an indoor environment control system using a smart window and, more specifically, to a system for controlling an indoor environment by matching characteristics of smart windows having different characteristics. To this end, an indoor environment control system using a smart window, according to the present invention, comprises: at least two smart windows that change color according to the magnitude of supplied voltage; an internal illuminance sensor formed inside each smart window to measure internal illuminance; an external illuminance sensor provided outside each smart window to measure external illuminance; a main control part for calculating the transmittance of each smart window by using the internal illuminance and the external illuminance provided from the internal illuminance sensor and the external illuminance sensor, and calculating the magnitude of voltage supplied to each smart window so that the difference between the calculated transmittances becomes less than or equal to a set value (N); and a unit control part for supplying, to each smart window, the magnitude of voltage provided from the main control part.
