Description

Daylight Collecting Louver System With Thermal Environment Control Function The present invention relates to a light-concentrating daylighting louver system equipped with a thermal environment control function, and more specifically, to a light-concentrating daylighting louver system that can improve the indoor thermal environment and contribute to saving heating and cooling energy by sensing thermal environment information through a sensor and controlling the angle of the louver, cross-flow fan, and/or PTC heater based on the sensed thermal environment information. Concentrating daylighting louvers are devices installed on windows to efficiently regulate incoming light and bring natural light into the interior; they primarily serve to maximize natural lighting by effectively reflecting or diffusing sunlight indoors. Generally, louvers are designed in the form of angle-adjustable blades or slats to control the angle and amount of light, blocking strong sunlight in the summer and allowing sunlight to enter in the winter. The above-mentioned light-collecting louvers are an eco-friendly building device that is increasingly being used in residential buildings as well as commercial buildings, as they reduce electricity consumption by using less artificial light, help regulate indoor heat to reduce cooling and heating costs, and make the indoor environment more comfortable through natural lighting. Conventional light-concentrating daylighting louvers are primarily controlled by completely allowing or completely blocking sunlight, or by blocking glare by reflecting incoming sunlight through the angle of the slats according to the sun's altitude. Therefore, there is a need to develop a light-collecting louver system capable of adjusting the angle of the slats according to thermal conditions to improve the indoor thermal environment and reduce heating and cooling energy consumption.
