Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of louvered photovoltaic building facade, as depicted in figs. 1 and 2, comprise external wall 1 and be located at the photovoltaic module 2 outside external wall 1, photovoltaic module comprises component framework and is located at the multiple louvered photovoltaic fin 9 on component framework, and louvered photovoltaic fin 9 is connected with component framework by turning cylinder 3.Wherein, the kind of external wall 1 can be safeguard wall and load bearing wall, also can be traditional glass curtain wall and window; Louvered photovoltaic fin 9 is made up of the louver vane and annex thereof laying photovoltaic cell.
Have the air flow channel 8 for air circulation between photovoltaic module 2 and external wall 1, and the gap of air between louvered photovoltaic fin 9 enters air flow channel 8, the gap between louvered photovoltaic fin 9 is air flow channel entrance.Louvered photovoltaic fin 9 can be generated heat while reception solar power generation, the rising of temperature can reduce its generating efficiency, the gap of air between louvered photovoltaic fin 9 enters air flow channel 8, air in air flow channel 8 is subject to the heat radiation of louvered photovoltaic fin 9 and ambient windstream and rises, be discharged to the outside environment from upper gap, thus take away the waste heat of louvered photovoltaic fin 9.Thus, louvered photovoltaic fin 9 can work shining upon preferably under corner condition, and its open form can take away waste heat by ambient air again and to be unlikely to temperature rise too high, thus ensures the efficient work of photovoltaic cell.
Photovoltaic module 2 is located on external wall 1 by the horizontal section bar of aluminium alloys hanging seat 5 and vertical aluminium alloy extrusions 6, and is fixed by bolt 4 and corner brace.
The bottom of air flow channel 8 can be selected to be provided with the weather strip for isolated air, air is forced to enter from the gap between louvered photovoltaic fin 9 dispersedly, instead of enter from the bottom of air flow channel 8, such air-flow presses close to louvered photovoltaic fin 9, is more conducive to take away heat.
Photovoltaic building facade also comprises the controller for adjusting louvered photovoltaic fin 9 inclination angle, and this controller is connected with turning cylinder 3.Controller can be fixed on component framework, also can be placed in photovoltaic building.Controller can according to dimension, season, even the sunshine of one day highly automated adjusting louver formula photovoltaic fin 9 inclination angle, convenient and practical, and can combine with solar angle tracing system and realize the automatic tracing control of optimum angle of incidence.Louvered photovoltaic fin 9 can most efficiently generate electricity when receiving sunlight, greatly improves solar energy utilization ratio.In addition, in the application, photovoltaic module 2 and controller can be combined as louvered photovoltaic curtain wall.
Photovoltaic building facade also comprises the airflow guiding device for accelerating gas flow rate in air flow channel 8, and this airflow guiding device is connected with air flow channel 8.
Concrete, louvered photovoltaic fin 9 can be fixed on curtain wall sub-frame column by control rotating shaft, turning cylinder 3 can be connected with machine control unit, realize the inclination angle of Non-follow control or its blinds of Electronic control, also can get a local optimum angle of incidence installs fixing, best power benefit under realizing non-controlling.
Louvered photovoltaic fin 9 can make according to common photovoltaic panel production method, the stream that generates electricity can be derived by wire, the width of blinds and the position of laying cell piece can be calculated by local sun declination, need avoid the shade of the overlapped generation of louvered photovoltaic fin 9 as far as possible.
When louvered photovoltaic fin 9 is opened, gap each other can make the air between external environment condition and the gap between external wall 1 and photovoltaic curtain wall fully circulate, photovoltaic panel can be taken away in time to generate electricity the heat simultaneously produced, be conducive to louvered photovoltaic fin 9 and keep efficient duty.Evening or winter, louvered photovoltaic fin 9 can close, and the air between obstruct external wall 1 and photovoltaic curtain wall gap and the convection current of ambient air outside, play effect of heat-insulation and heat-preservation.
Photovoltaic curtain wall can be made into modular, also can be customized according to given shape.When being made into modular, louvered photovoltaic fin 9 and its component framework form a unit, have independently junction box and extraction wire.Can set out wind/air intake between photovoltaic curtain wall unit and unit, air-out/air intake also can realize cross-ventilated intervention in its folding of Artificial Control.
Louvered photovoltaic curtain wall can control folding angle, realizes shaded effects in summer, and can reduce because sun direct irradiation makes building temperature raise too fast brought air conditioner load.The air of inside and outside convection current also can take away waste heat, slows down building temperature and raises.
Solar incident angle differed greatly with local latitude, season, sooner or later difference, and the generating efficiency of photovoltaic cell is comparatively large by the impact of solar incident angle, and its best generating effect is when the vertical photovoltaic panel of sun incident light.Although it is large to build particularly external wall of high-rise building 1 area, facade perpendicular to the ground is not the optimum angle of incidence of photovoltaic cell capable of generating power.The photovoltaic battery panel of the application is made into blinds form, is installed in support framework, can adjust its folding angle, makes cell piece with best angle in the face of sunlight, thus reaches best generating effect.
The folding of louvered photovoltaic fin 9 can not only obtain good sun irradiation angle, and can also control the convection velocity of air between double-deck elevation of building that elevation of building and photovoltaic curtain wall form and outside ambient air, realization can type of respiration building.Hot summer can take away waste heat by accelerating cross-ventilation, and cold winter can close louvered photovoltaic fin 9, makes the air between double-skin facade form air heat-insulation layer, plays insulation effect.Louvered photovoltaic fin 9 coordinates building ventilation device can realize Multiple air convection current, regulates building temperature.
Louvered photovoltaic fin 9 is also a kind of solar protection devices while obtaining optimum angle of incidence generating, plays the effect intercepting direct sunlight, can give the comfortable work of building construction, living environment in vertical window outdoor surface.
By arranging louvered photovoltaic fin 9 on external wall 1, can receive solar electrical energy generation is on the one hand also architectural power supply, can save traditional fossil energy, reserved resource, reduce carbon discharge capacity; As building external decoration, can be building blocks of function and decoration element on the other hand, change the purposes that traditional architecture external decoration is purely attractive in appearance; In addition, the minimizing effect of the air conditioner load reached can reduce traditional energy consumption again, and the negative environmental consequences that multiple air-conditioning brings.
