Abstract: An enclosed air conditioning unit includes a filter section and a cooling section through which intake air passes before being discharged into a space within a building. The orientation of the filter section and cooling section is substantially vertical, and the airflow path through the filter section and the cooling section is substantially horizontal, resulting in reduced face velocities across these components, thereby increasing filtration efficiency and cooling effectiveness, while allowing the physical size and configuration of the air conditioning unit's enclosure to be the same as or smaller than the enclosures for conventional air conditioning units having comparable or lower performance.

Abstract: Equipment and a method for preheating a continuously moving steel strip, in particular before feeding the same into a continuous annealing or hot-dip galvanizing furnace, involves the continuous movement of the steel strip in a preheating chamber including a preheating circuit having at least one preheating tube, the inner surface of which is in contact with externally-recovered burnt gases (e.g. from the furnace). A portion of the outer surface of the preheating tube is disposed directly opposite a surface of the strip in order to provide a first preheating mode by irradiating heat onto the strip and the walls of the chamber, and a second preheating mode, mainly by convection, of a gas constituting a controlled atmosphere in the preheating chamber.

The air discharged through the connecting sleeve is redirectable substantially completely in different discharge directions with pivoting of the connecting sleeve. The connecting sleeve has a greater cross-sectional area at the inflow opening than at the outflow opening and at least one air guiding wall is formed in the connecting sleeve.

Abstract: A backflow preventer for use in a multiple fan array system that draws air from an inlet area and expels it into a discharge area includes a main body defining an open front end and an open rear end and is adapted for attachment to a fan of the fan array system adjacent an inlet of the fan. Doors are attached to the main body and configured for movement between an open position in which air is permitted to enter through the open front end and a closed position in which the doors block the open front end and air is prevented from entering through the open front end. The doors are movable between the open position and the closed position by a pressure differential between the inlet area and the discharge area. The doors in the open position form a tapered intake passageway that funnels air into the fan.

Abstract: A one-way vent for installation in a panel aperture is described. The vent includes a frame made of a first material, and valve and seal members both made of a second material, which has a lower stiffness than the first material.

Abstract: A gas water heater includes a water tank, a combustion chamber, a burner, a heat exchanger tube at least partially within the water tank, and a fan. The burner receives fuel gas and primary air from a first air-supply channel to create a primary air-fuel mixture for combustion in the combustion chamber with secondary air. The primary air-fuel mixture has a gas concentration above the upper explosive limit of the fuel gas. Secondary air is supplied through a second air-supply channel to the combustion chamber. The secondary air creates a low excess air ratio (e.g., below 1.5) for combustion in the combustion chamber. A totally sealed channel is defined from the air inlet of the fan to the heat exchanger tube.
