A system and method of vent placement within a building is provided for improved passive ventilation. Vents are provided within the dividing structures or material layers that form the building's exterior and interior walls, ceiling, roof, floor, and / or intermediate story-defining “ceiling-floors.” Preferably, each vent is not a conventional ventilation stack and is oriented generally along a planar portion of the dividing structure within which the vent is positioned. Preferably, each vent is substantially entirely contained within its associated dividing structure. Vents are provided in corner sections of exterior walls, roof-portions, and the bottom floor of the building. Vents are also provided in corner sections of the ceiling portions, floor portions, and wall portions that define the interior rooms of the building. The vents are preferably vertically aligned throughout a substantial portion of the height (or more preferably substantially the entire height) of the building, at one or more horizontal positions thereof, to thereby produce one or more substantially vertical flows of air upward and out of the building, without the use of stack vents.

The invention discloses a ventilation device, which aims to solve the problem that the conventional ventilation device does not have an air adjusting function. The device comprises a pedestal, a high-speed air blower and an annular ejector, wherein the high-speed air blower is arranged at the bottom of the pedestal; the annular ejector is arranged at an air outlet of the high-speed air blower and is fixed on the pedestal; and the air inlet or the air outlet of the high-speed air blower is provided with a vapor generator which is fixed on the pedestal for producing water vapor. In the ventilation device, the water vapor is produced through the vapor generator and is ejected through an atomization nozzle at a high speed to produce fog of smaller granularity, so that a hot air flow can more easily absorb the latent heat of vaporization, and the ventilation device has a humidification effect and a heat absorption and temperature reduction effect on a large amount of hot air sucked by the annular nozzle, and brings comfortable cool air similar to air on the shore of a lake or a sea to the surrounding environment. In the ventilation device, an external circulating device is not required to be mounted, so the cost is low; the space is not required to be closed, so that air convection is guaranteed; and the ventilation device is more energy-saving in the same temperature reduction range compared with a fan and an air conditioner, and can be used conveniently and safely.

The invention relates to a ventilation arrangement system in coal mining, in particular to a U+H type ventilation system which is suitable for a highly gassy mine and solves a plurality of problems of the conventional ventilation system in the coal mine working face mining process. Five tunnels are arranged to form a working face tunnel, wherein three air inlet tunnels and two air return tunnels forms an U+H ventilation system. The invention has small ventilation resistance and large wind-crossing section, air volume and windblown mine gas capacity and is suitable for the mining of the highly gassy mine.

The invention discloses an adjustable ventilation device and a control system therefor. An air regulation apparatus is fixed on a floor support, and a ventilation floor is laid on a square frame. The square frame is provided with wind shield plates and movable wind shield plates, and ventilation gaps in a horizontal direction are respectively formed between the adjacent two wind shield plates. Inner sides, at which two ends of each wind shield plate are located, of two frames are respectively provided with a guide rail in a length direction. Two ends of each movable wind shield plate are respectively disposed on guide rails of the two frames in a sliding manner. The movable wind shield plates are respectively in fixed connection with the same connecting plate, and the width of each ventilation gap between two adjacent wind shield plates is less than or equal to the width of each movable wind shield plate. The lower side of a strip-shaped connecting plate is provided with racks in the length direction of the guide rail, and a gear is engaged with the racks. A torsional force steering engine drives the gear to rotate, so as to solve a problem that the effect of a convention air supply system is not ideal because a conventional ventilation floor structure is not reasonable and the ventilation cannot be changed easily. The invention belongs to the field of cabinet temperature control.
