A rotary apparatus includes a motor, a plurality of gears including an output gear, and a housing accommodating the plurality of gears and the motor. The housing includes a first surface portion, a second surface portion facing the first surface portion and spaced apart from the first surface portion, and a sidewall portion provided at an outer peripheral portion of the first surface portion and the second surface portion and supporting the first surface portion and the second surface portion. One of the first surface portion and the second surface portion includes a vibration damping part opposing the output gear.

A blowout structure of an air conditioner according to the present invention includes a wind direction adjuster that is arranged in a case, can change a direction of wind blown out according to a rotation angle, and closes a ventilation passage inside the case so as to inhibit blowout of the wind. Inside the case, a contact surface with which a wind direction adjuster 2 in a state of closing the ventilation passage comes into contact and a reverse surface that allows an airflow flowing back to the upstream side from the contact surface to be reversed to the downstream side.

This document describes a high efficiency dehumidification system (HEDS) and method of operating the same. The HEDS systems and physical implementations can include a variety of equipment, such as fans, fluid-conveying coils, tubing and pipes, heat transfer coils, vents, louvers, dampers, valves, fluid chillers, fluid heaters, and/or the like. Any of the implementations described herein can also include controls and logic, responsive to one or more sensors or other input devices, for controlling the equipment for each implementation described herein. The HEDS system utilizes heat transfer between the fluid within the fluid-conveying coils and air passing over the coils to convert humid air into dehumidified air.

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. Each of the plurality of louver blades include a catch member that longitudinally extends between a first blade end and a second blade end of a corresponding louver blade. The louver may also include a rotation assembly configured to rotatably couple with the plurality of louver blades and the frame. The plurality of louver blades may autonomously rotate about rotation members of the rotation assembly based on environmental elements captured in the catch member such that the plurality of louver blades are configured in an open position in response to no water in the catch member and are configured in a closed position in response to an amount of environmental elements in the catch member.

There is provided a wall port cover to be installed in building wall ports. Wall ports are simply openings in a wall or ceiling of a building which may be used to house electrical panels, HVAC systems, access panels, lighting switches, and the like. The wall port cover comprises an engagement means which is rotatable between an engaging position and a releasing position. In the engaging position, the engaging means extend beyond the wall port cover to engage a top surface of the wall or ceiling drywall panel to support and retain the wall port cover within the vent opening. In the releasing position, the engaging means are retracted within the wall port cover to disengage from the top surface of the wall or ceiling drywall panel to allow the wall port cover to be removed from the vent openings.

An active grille shutter arrangement having an assembled modular frame with a plurality of primary frame pieces formed by extrusion. Each one of the plurality of primary frame pieces has a first end, a second end and at least one key slot extending between the first end and the second end. Each of the plurality of frame pieces also includes a hollow bore extending through the each one of the plurality of primary frame pieces forming an aperture at the first end and an aperture at the second end. When the modular frame is assembled there is an upper frame portion and lower frame portion, both formed from one of the plurality of primary frame pieces. The arrangement also includes a number of alternate frame and vane pieces that allow several different active grille shapes and configurations to be formed.
