Abstract: A damper arrangement is described which moves dampers from a location closer to an air source to a boot located adjacent to a ceiling register, grill, or the like, thereby allowing technicians or owners to more readily make adjustments. A substantially flush boot collar mounting preserves leak free flow, and keeps insulation installation simple. An internal adjustment mechanism, such as a loop, avoids the need to pull the ceiling grill from the ceiling. Both insulation and subsequent adjustment are simplified.

Abstract: An integrated avionics bay in a floor area can be provided with adequate ventilation. The structure of an aircraft cockpit floor is able to integrate at least one bay, with a walking floor in the cockpit, a structural volume and a bay integrated in a space of the liberated structural volume. The bay as integrated in a horizontal position in this space includes a peripheral frame with at least one protective cover with a direct access to the bay at the floor level and a lower wall with a rear face access. Side openings formed in the frame can couple with vertical walls to allow fresh air blowing from the rear wall of the bay via a flow from rearwards to upwards to reach the top cover and an air extraction by an upper surface extractor.

Abstract: A coaxial ventilator (20) exchanges atmosphere between parts of a building (22) that are at differing heights. The coaxial ventilator (20) includes an outer conduit (24) that extends from an upper end (42) thereof downward to a lower end (44) thereof. The outer conduit (24) surrounds an inner conduit (62) that extends substantially the entire length of the outer conduit (24). Both the outer and inner conduits (24, 62) are open at their respective upper ends (42, 66) and lower ends (44, 68). Temperatures of atmosphere both surrounding and within the outer conduit (24) and the inner conduit (62) induce an exchange of atmosphere between the coaxial ventilator (20) and surrounding atmosphere.

Abstract: Provided is a server room cooling apparatus and method using natural air. The server room cooling apparatus includes an inlet part to take in outside air, a spray part to spray mist on the outside air that is taken in, and a supplying part to supply the outside air on which the mist is sprayed to the inside of a server room.

Abstract: Embodiments of the invention provide an air conditioning unit and a ventilator. The ventilator has an impeller to draw outside air into an enclosure and cause air within the enclosure to be exhausted to the outside. The ventilator can be tied into the air conditioning unit's control system and act to supplement the cooling and ventilation needs of the space. Alternatively, the ventilator can have a separate integral control system. By having a separate control system, the ventilator can operate as a stand-alone device.
