Background technique

At present, the glass curtain wall is popular among real estate developers and consumers due to its beautiful appearance, and its application in small and medium-sized cities is also increasing rapidly. Although the glass curtain wall can reduce the lighting load to a certain extent, the heat gain from solar radiation has increased significantly, and its thermal insulation performance The low energy consumption of the air conditioner also greatly increases. In order to solve this problem, many methods have emerged to enhance the thermal insulation of the glass curtain wall, such as broken bridge insulation, selection of special glass such as Low-e glass, and double-layer ventilation curtain wall.

The double-layer ventilated curtain wall is divided into an open exterior ventilated curtain wall and a closed interior ventilated curtain wall. The second type is suitable for heating areas and has higher requirements for equipment. The first type is relatively more common. The inner curtain wall is closed and hollow glass is used. , The outer curtain wall is equipped with closable air intake and exhaust outlets, and the heat is taken away through the hot aisle. At present, the application of the open external ventilation curtain wall needs to solve the problem of overheating and heat insulation of the hot aisle cavity.

The actual ventilation and lighting conditions of underground spaces such as underground garages are not optimistic. Compared with above-ground buildings, it is relatively difficult to provide natural lighting and ventilation for underground spaces. Mechanical ventilation can achieve good ventilation effects, but it will increase building energy consumption. The actual natural ventilation The effect is not good, and it is difficult to open skylights due to various factors.

Contents of the invention

Combining the above two situations, this utility model improves the traditional double-layer curtain wall, and proposes a heat-insulation, ventilation and daylighting system that combines the solar-driven curtain wall with the underground space, that is, the top of the outer curtain wall of the double-layer curtain wall and the interlayer of the curtain wall and the Vents are provided on the floors between the underground spaces to effectively reduce the radiation and convective heat gain of curtain wall buildings with underground spaces, thereby reducing building energy consumption.

The system consists of the outer curtain wall (1), the inner curtain wall (2), the upper air outlet on the top of the outer curtain wall (3), the curtain wall interlayer formed by the inner and outer curtain walls (5), and the lower air outlet on the floor between the bottom of the curtain wall interlayer and the underground space (4), the underground space (6) and the entrance and exit of the underground space (7), the steel keel (8) connecting the inner and outer curtain walls, the floor (9) supporting the inner and outer curtain walls, and the upper and lower air outlets correspond one by one, and make the underground space, the interlayer of the curtain wall and the Outdoor air connection.

The technical scheme of the utility model: set the upper air outlet (3) on the top of the outer curtain wall (1) of the double-layer curtain wall, and install the lower air outlet (4) on the floor (9) between the bottom of the curtain wall interlayer (5) and the underground space (6) , and install adjustable louvers and bottom-opening fire-resistant glass dampers respectively, and connect the outer curtain wall (1) with the connecting piece of the inner curtain wall (2) through steel keel (8) and bolts, the lower part is supported by the floor slab (9), underground The space (6) communicates with the outdoors through the underground space entrance (7), and the curtain wall interlayer (5) communicates with the underground space (6) through the lower air outlet (4) and communicates with the outdoors through the upper air outlet (3). In summer, the outdoor air temperature is high and solar energy is sufficient. Through the action of solar heat radiation, the air in the interlayer of the curtain wall is heated by the heat radiation, and the hot air gradually rises upwards and enters the atmosphere through the upper air outlet. An upward airflow is formed in the interlayer of the curtain wall, and the pressure decreases, thereby inducing the underground The low-temperature air in the space enters the interlayer of the curtain wall from the lower air outlet, which is beneficial to prevent heat transfer to the room and has a good heat insulation effect, while the air in the underground space is supplemented by the entrance (7) of the underground space, so that the underground space, the interlayer of the curtain wall and the outdoor environment form a good environment natural ventilation circulation. In winter, the upper and lower air outlets are closed to ensure airtightness, so that the air in the interlayer of the curtain wall absorbs solar energy and heats up to form a good insulation layer.

The adjustable louvers of the upper air outlet (3) can adjust the direction of the louvers according to the solar radiation conditions, thereby adjusting the ventilation volume in the curtain wall interlayer (5).

The beneficial effects of the utility model are: to overcome the traditional curtain wall building with high heat gain from solar radiation in summer, which causes excessive cooling load of the building and excessive building energy consumption caused by the large indoor cooling capacity; . Compared with the traditional naturally ventilated curtain wall, it utilizes the cold air in the underground space, which has a good heat insulation and cooling effect, and can solve the problem of ventilation in the underground space; Natural lighting can be fully utilized in occasions where lighting requirements are not high; secondly, this utility model is also simple in system, small in initial investment, and has great utilization value.
