SU1724830A1 - Aeration lantern for industrial buildings - Google Patents

Abstract

The invention relates to the construction, in particular to the structures of aeration lanterns, and can be used for the natural removal of air in industrial buildings with heat generation and the ratio of height to width H / H 0.5. The aeration lamp is made in the form of interconnected sloping with a slope to the outside and forming a neck vertical plates installed in the neck area, each wind-breaking attachment equipped with a vertical plate connected to the free end, and the rain cover is curved. 2 Il.

Description

The invention relates to heating and ventilation technology and can be used for the natural removal of air in industrial buildings with heat generation and the ratio of height to width.

Rine building - 0,5. AT

The purpose of the invention is to increase the efficiency of the lamp.

Figure 1 is a schematic of an aeration lantern for industrial buildings; figure 2 - the same, axonometrics.

The aeration lantern for industrial buildings consists of a housing 1 with outlets 2, a rain-protection hood 3, wind-breaker attachments, each made in the form of interconnected inclined with a slope to the outer side of the plate 4 and two vertical plates 5 and 6, turning guide plates 7 mounted on

horizontal axes x 8 in the area of the neck 9 formed by the vertical plates of 5 wind-breakdown attachments. The rain cover 3 is curved with a radius of curvature determined from the ratio R (1.2-1.4) A, where A is the throat width 9. The aeration lamp is installed on the roof 10 of the industrial building.

Aeration lantern.dl industrial buildings works as follows.

The air entering the lamp from a room (not shown) in the neck 9, under the rain cover 3, is divided into two streams flowing around the edges of the rain cover 3, and enters through the outlets 2 to the outside. The amount of air removed through the aeration lamp is controlled by means of rotary guide plates 7.

about

The aerodynamic resistance of the aeration lamp to the passage of air, expressed in the fractions of the velocity pressure at the throat, is equal to.

Aeration lamp designed

for industrial buildings with a ratio

and height to width 5: 0,5. Under this condition

The roof of the building is located in an aerodynamic shadow zone characterized by a negative dynamic pressure value.

The aeration lamp, located in the rarefaction zone, is non-inflatable.

An additional device to ensure the unattractiveness of the aeration lantern, as well as to prevent precipitation into the lantern, is the curvature of the coating and the presence of wind-breakdown consoles, which facilitate the sliding of the incident flow over the surface of the coating without flowing into the lamp.

Claims (1)

Claims of aeration lamp for industrial buildings, including a housing with outlets, rain cover, wind-breaker attachments, each made in the form of interconnected inclined with a slope to the outer the side and the throat-forming vertical plates, and the swiveling guide plates mounted on horizontal axes in the throat zone, which is characterized by the fact that in order to increase the efficiency of the lamp, each wind-breaker attachment is equipped with a vertical plate connected to the free end of the inclined plate, and the rain visor has a curvilinear shape with a radius of curvature determined from the ratio R (1.2-1.4) A, where A is the throat width.
