Abstract: A smart window, and production method therefor, uses glass beads made from glass material instead of a polymer matrix of the conventional smart window. This makes the liquid crystal's size, shape and arrangement constant by placing the liquid crystal outside the glass beads, thereby securing high stability and chemical resistance, avoiding haze, having low operating voltage, and having improved optical, for example, broad variable range of light transmittance between OFF (light impermeable) and ON (light permeable) states.

Abstract: A smart glass uses a guided self-assembled photonic crystal, including a photonic crystal layer that is interposed between a pair of conductive glass plates. The smart glass includes a first material and a second material having a different refractive index from the first material and surrounding the first material. Thereby, the smart glass has a color, even when a dye is not included, by strongly reflecting light in a specific wavelength range incident to the photonic crystal layer. This is because the first material is formed regularly to have a constant distance by guided self-assembly, and the smart glass thereby may obtain a target color by randomly adjusting the distance between the first materials.

Abstract: An air conditioner (AC) indoor unit includes a housing having an inlet and an outlet; a heat exchanger arranged inside the housing; a blower fan for sucking in air at the inlet to be subject to heat exchange with the heat exchanger, and discharging the heat-exchanged air out of the outlet; and an air flow control device for controlling an air flow discharged from the outlet by sucking in air around the outlet. The AC indoor unit may control the direction of a discharged air flow without a conventional blade structure, thereby increasing an amount of discharged air, reducing circulation noise, and enabling design differentiation.

Abstract: An air blowing unit of an air conditioner includes a housing to guide suction and discharge of air, a centrifugal fan positioned inside the housing, and a motor to drive the centrifugal fan. The centrifugal fan includes a base coupled to a motor shaft coupled to the motor, a plurality of blades disposed spaced apart from each other in a circumferential direction of the base to guide air introduced in an axial direction of the base to the circumferential direction, a leading edge provided to the blades and arranged close to the motor shaft, a trailing edge provided to the blades and facing in an outer circumferential direction of the base, and at least one first blade of the blades, the leading edge of the first blade being shorter than the leading edge of the other blades.

Abstract: A smart window includes a pair of transparent electrodes spaced apart to face each other. Porous aerogel is interposed between the pair of transparent electrodes. Liquid crystal is interposed between the pair of transparent electrodes and filliping pores of the aerogel. The smart window scatters more light because an interface between the aerogel and liquid crystal is maximized by filling pores of the aerogel with the liquid crystal.

Abstract: A fan assembly for a centrifugal blower and an air conditioning apparatus including the same are provided. The fan assembly for the centrifugal blower includes a first support configured to receive a driving force from a driving source to rotate, a plurality of blades having one end supported by the first support and arranged with an interval in a circumferential direction of the first support, and a second support configured to support the other end of the plurality of blades and including an air inlet formed therein, wherein the plurality of blades include a first portion disposed adjacent to the air inlet, and a second portion further from the air inlet than the first portion and having a wider width than the first portion, and at least one of the first and second portions has a constant width.
