Automatic ventilation system for low tier building

Abstract

An automatic ventilation system for a low tier building comprises a site foundation, a ceiling, a foundation ventilation layer, bottom-layer rooms, top-layer rooms and a loft. The foundation ventilation layer is arranged on the upper portion of the site foundation, and foundation unidirectional air inlets are formed at 1 / 3-2 / 3 height of a foundation exterior support on the periphery of the foundation ventilation layer. A plurality of bottom floorslab unidirectional vents are formed on a bottom-layer floor plate between the foundation ventilation layer and the bottom-layer rooms. A plurality of middle floorslab unidirectional vents are formed on a middle floor plate between the bottom-layer rooms and the top-layer rooms. The automatic ventilation system has the advantages of reasonable layout, no need of power and zero noise. Excessive moisture and peculiar smell in air are removed while dust and pollen in air are filtered out and pure fresh air is provided to the rooms by ventilation. According to the design, fresh air is introduced to the inside of the building skillfully, and air ventilation cannot be blocked by closed doors.

Description

technical field [0001] The invention relates to an automatic ventilation system for a low-storey building, belonging to the technical fields of indoor air cleaning technology and indoor ventilation. Background technique [0002] The drivers of natural ventilation in house design are wind and temperature. The cold air is denser than the hot air, so the cold air is heavier and sinks into the depression; the hot air is lighter and rises upward. The airflow usually flows from the positive pressure area to the negative pressure area. If the airflow encounters obstacles on the way, it will cause the airflow to gather, thus forming a positive airflow area on the windward side. The wind pressure acting on the decoration design depends on the wind direction, wind speed and the decoration design shape of the clubhouse. The difference in temperature between indoor and outdoor will cause the difference in air density, resulting in a pressure difference. Therefore, for each opening, t...
