Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Natural ventilation building as shown in Figure 1, it comprises foundation construction thing 1, and foundation construction thing 1 comprises southern side roofing 2 and north side roofing 3, and southern side roofing 2 is lower than north side roofing 3, to constitute wing roof, so that form higher-pressure region and low-pressure area.The top of roofing 3 is provided with blast cap 10 in the north side, is beneficial to the formation of hot pressing.Be respectively equipped with a room with a northern exposure face metal sheet 7 and room with a southern exposure face metal sheet 9 on slope, roofing south, southern side 4 and the slope, north side roofing south 15, a room with a northern exposure face metal sheet 7 lower ends are provided with cornices 8, and southern side roofing north slope 5 is provided with ventilation stack 11 with southern sloping 15 bottoms of north side roofing, thereby forms double-deck roofing.Roofing 2 tops stretch out from the southern side for southern side roofing north slope 5, and form with slope, southern side roofing south 4 and to catch air port 6, and outside natural wind gets into Zhongtings through the ventilation stack 11 that double-deck roofing constitutes.Roofing 2 tops, north side roofing 3 middle parts and southern side roofing 2 and north side roofing 3 joints are respectively equipped with first Electric air valve 12, second Electric air valve 14 and the 3rd Electric air valve 13 in the southern side; Foundation construction thing 1 is provided with on regulation and control window 16, the first Electric air valves 12, second Electric air valve 14, the 3rd Electric air valve 13 and the regulation and control window 16 and is connected with wind pressure sensor.
A room with a northern exposure face metal sheet 7 is raise by the solar radiation temperature with room with a southern exposure face metal sheet 9 and blast cap 10; The single line arrow is represented sunray among Fig. 1; Poor with the cold air formation hot pressing of bottom Zhongting, quicken air-flow and rise (double-lined arrow is represented air-flow direction among Fig. 1), strengthen air circulation.Under the acting in conjunction of blast and hot pressing, natural ventilation is strengthened in the Zhongting, becomes " motor " of building interior natural ventilation, thereby the air that drives each room, bottom flows, and forms complete natural ventilation system.
When the utility model uses; Utilize wind pressure sensor (importing setup parameter in advance) automatically to regulate the opening angle of first Electric air valve 12, second Electric air valve 14, the 3rd Electric air valve 13 and regulation and control window 16 according to climate state or close, thereby reach good effect of natural ventilation.
In most cases, serve as the air port with regulation and control window 16 in the natural ventilation system, form, area size and the installation site of regulation and control window 16 influence drafting efficiency, indoor air flow tissue and indoor thermal comfort.Cardinal wind at natural wind is the area of southeaster, its southeast to regulation and control window 16 satisfying on the basis of energy-conservation requirement, open big automatically to proper angle; On the contrary for fear of being blown into of northwest cold wind in winter, the north-westward regulation and control window 16 of building is adjusted to smaller angle automatically.
