According to the present disclosure, a thermal processing apparatus includes a chamber that forms a thermal processing space of a substrate, a substrate support unit that is located at a lower portion of the thermal processing space and supports the substrate, and a microwave unit that is located at an upper portion of the thermal processing space and forms an electromagnetic field by the microwave in the thermal processing space.

Abstract: Disclosed is an air conditioner includes a cabinet that is configured to mount on an indoor ceiling. The air conditioner also include a front panel that is coupled to the cabinet and having an air inlet and outlet. The air conditioner further include a suction panel that is coupled to the front panel and configured to move between an open positione in which air is able to circulate through the air conditioner and a closed position in which air is blocked from circulating through the air conditioner. The air conditioner further include a sensor unit that is mounted on the suction panel, that is configured to move together with the suction panel and that is configured to detect a position of a person in the indoor place. In addition, the air conditioner also include a controller adjusting a direction of air flow from the outlet based on the deteded position of the person.

Abstract: An air conditioner includes a cabinet positioned on an indoor ceiling. The air conditioner also includes a front panel that is coupled to the cabinet and has an air inlet. The air conditioner further includes a suction panel coupled to the front panel and configured to move to open or close the inlet. In addition, the air conditioner includes a sensor unit positioned on the suction panel, configured to detect a position of an indoor person, and configured to move downward with respect to the suction panel in response to an operation instruction.

Abstract: An air conditioner includes a cabinet configured to define an outer appearance of the air conditioner. The air conditioner also includes a front panel coupled to the cabinet and having an intake hole. The air conditioner further includes a fan assembly positioned within the cabinet and configured to guide a flow of air in the cabinet. The air conditioner further includes an intake panel configured to move to open or close the intake hole in response to a control signal. In addition, the air conditioner includes at least one noise reducing part positioned in the intake panel and configured to reduce a noise having at least one frequency bandwidth.

Abstract: In an air conditioner, air-supply passages cross air-discharge passages, and heat exchangers are disposed at intersections between the air-supply passages and the air-discharge passages. This increases the effective heat-exchanging areas of the heat exchangers. In addition, the air conditioner is configured such that the air conditioner can be easily installed and repaired even when the air conditioner is rotated to be properly connected with air-supply ducts and air-discharge ducts.

Abstract: An air conditioner includes a cabinet and a fan assembly positioned within the cabinet and configured to guide air inside of the cabinet toward an outside of the cabinet. The air conditioner also includes a front panel coupled to the cabinet and configured to communicate air into the cabinet from the outside. The air conditioner further includes an intake panel moveable with respect to the front panel and configured to open or close an intake portion defined by the front panel. In addition, the air conditioner includes a guide unit positioned between the front panel and the intake panel and configured to partition the intake portion into at least two intake passages.

Abstract: A ventilation apparatus, a heat exchange apparatus, and a heat exchange element therefor are provided. The heat exchange element includes a heat exchange sheet, a plurality of first ribs arranged on one surface of the heat exchange sheet that guides a first gas flowing along the one surface of the heat exchange sheet, and a plurality of second ribs arranged on the other surface of the heat exchange sheet and parallel to an arrangement angle of the first rib that guides a second gas flowing along the the other surface of the heat exchange sheet. The first and second ribs alternately support the heat exchange sheet. The heat exchange element may prevent the sag phenomenon of the heat exchange sheet without increasing duct resistance.

Abstract: A ventilating apparatus, a heat exchange apparatus, a heat exchange element, and a rib therefor are provided. The heat exchange element includes a plurality of heat exchange sheets which are multi-stacked, and a plurality of ribs arranged between the heat exchange sheets to form ducts with the heat exchange sheets. Each of the plurality of ribs includes an irregular structural surface including an uneven portion. The uneven portion may include a recess portion, a protrusion portion, or a combination of a recess portion and a protrusion portion, which generates a turbulent flow in a heat exchange gas flowing through the duct. Such heat exchange element having such a rib may minimize duct resistance by suppressing a laminar flow and growth of a boundary layer in airflow of outdoor and indoor air passing through a heat exchanger, and may further increase heat exchange efficiency because the heat exchange gas may be introduced/exhausted smoothly at a low flow velocity.

Abstract: An air conditioner may be provided having a housing and a fan provided within the housing. In this regard, the fan may be configured to draw air into the housing and direct the air radially outward. Additionally, a heat exchanger may be provided within the housing. The heat exchanger may be configured to exchange heat with the air which is directed radially outward. Also, at least one airflow guide may be provided on the housing and extending in a flow direction of the radially directed air. In this regard, the airflow guide may be configured to guide a discharging of air that has exchanged heat.
