Abstract: A damper device according to an embodiment of the disclosure includes a frame having an opening and a blade coupled to the frame to open/close the opening, the damper device including a first bracket provided on the frame such that the blade is rotatably coupled thereto, a second bracket provided to correspond to the first bracket, a first hole and a second hole formed bilaterally symmetrically on the first bracket and the second bracket, and a motor connected to rotate the blade through one of the first hole and the second hole, wherein the blade is connected to the first hole when rotated in a first direction, and is connected to the second hole when rotated in a second direction opposite to the first direction.

Abstract: The present disclosure relates to a ventilation apparatus including a housing including: an intake flow path provided to draw outdoor air into an indoor space and an discharge flow path provided to discharge indoor air to the outside, a cover covering the housing, a total heat exchanger configured to exchange heat between air flowing in the intake flow path and air flowing in the discharge flow path, and a dehumidification unit including a heat exchanger provided on the intake flow path configured to remove moisture in the air flowing in the intake flow path and a drain tray configured to collect condensate generated from the heat exchanger, wherein the housing includes a first housing including a first hole asymmetrically formed on one surface of the housing with respect to a center line of the one surface extending in a long axis direction and a short axis direction of the one surface and configured to allow the drain tray and the total heat exchanger to be withdrawn from the outside of the housing, and a s

Abstract: A display apparatus includes a pixel part including a plurality of pixels, and a gate driving circuit. Each of the plurality of pixels is driven in one first scan period and one or more second scan periods during one frame in a driving mode driven at a first driving frequency lower than a maximum driving frequency.

Abstract: A total energy management system for high energy efficiency of a logistics center includes: an energy management system (EMS) server for collecting real-time data associated with the logistics center, wherein the EMS server processes the real-time data and generates at least one of real-time temperature data, real-time humidity data, renewable energy data, and electric power data of the logistics center; and an artificial intelligence (AI) server for outputting at least one of temperature mapping data, defrosting time determination data, and an energy operation guide in the logistics center based on at least one of the real-time temperature data, the real-time humidity data, the renewable energy data, and the electric power data received from the EMS server, wherein the EMS server switches between a plurality of management modes having different operating conditions for the logistics center based on at least one of the temperature mapping data, the defrosting time determination data, and the energy operation

Abstract: A method for preventing occurrence of creeping electrical discharge at a resin surface, the method being characterized by including dispersing nanosized inorganic fine particles in a resin, thereby preventing occurrence of creeping electrical discharge at the surface of a cured product of the resin.
