Solar driven heat-insulation ventilating and lighting system with curtain wall combined with underground space

Abstract

The patent discloses a solar driven heat-insulation ventilating and lighting system with a curtain wall combined with an underground space. The solar driven heat-insulation ventilating and lighting system with the curtain wall combined with the underground space comprises an outer-layer curtain wall (1), an inner-layer curtain wall (2), an adjustable louver air vent (3), a curtain wall interlayer (5), an air vent (4), an underground space (6), an underground space entrance-exit (7), a steel keel (8) and a floor plate (9), wherein the adjustable louver air vent (3) is arranged in the top of the outer-layer curtain wall; the curtain wall interlayer (5) is formed by the inner-layer curtain wall and the outer-layer curtain wall; the air vent (4) is arranged in the floor plate between the bottom of the curtain wall interlayer and the underground space; the steel keel (8) is used for connecting the inner-layer curtain wall with the outer-layer curtain wall; the floor plate (9) is used for supporting the inner-layer curtain wall and the outer-layer curtain wall. By using the system, a basement and the curtain wall interlayer are enabled to communicate with outdoor air, the air vent is opened in summer to form a natural ventilation to take away heat, and is closed in winter to form a heat-preserving air layer for reducing heat loss, and the lower air vent (4) facilitates the lighting, the ventilating and the aerating of the underground space. By using the solar driven heat-insulation ventilating and lighting system with the curtain wall combined with the underground space, the properties of heat preservation in winter and heat insulation in summer are enhanced, meanwhile, the ventilation and aeration properties and the illumination condition of the underground space are improved, the energy consumption of a building can be reduced, the comfort degree of a human body can be effectively improved, and the solar driven heat-insulation ventilating and lighting system with the curtain wall combined with the underground space is generally applicable to a double-layer curtain wall building with the underground space.

Description

technical field [0001] The present invention relates to a curtain wall building energy-saving system, in particular to a heat-insulation, ventilation and daylighting system that combines a solar-driven curtain wall with an underground space. The system is set to connect the basement, the curtain wall interlayer, and the outdoor air to open and absorb solar energy in summer to form a natural ventilation. Thermal, closed in winter forms an insulating air layer to reduce heat loss. Background technique [0002] 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 s...

Problems solved by technology

[0004] 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
