具体实施方式Detailed ways

下面结合附图对本发明作进一步详细说明。The present invention will be further described in detail below in conjunction with the accompanying drawings.

参看图1，一种节能光伏幕墙系统，包括建筑墙体1、幕墙框架单元2和光伏板3，所述幕墙框架单元2用自攻螺栓固定在墙体1外侧，所述光伏板3与幕墙框架单元2连接，并与墙体1之间形成空腔4。所述空腔4顶部设置吸风管道5，所述吸风管道5里设置风机6，所述风机6通过管道连接有出风口7。1, an energy-saving photovoltaic curtain wall system, comprising a building wall 1, a curtain wall frame unit 2 and a photovoltaic panel 3, the curtain wall frame unit 2 is fixed on the outside of the wall 1 with self-tapping bolts, and the photovoltaic panel 3 is connected to the curtain wall. The frame unit 2 is connected, and a cavity 4 is formed between the frame unit 2 and the wall body 1 . A suction duct 5 is arranged on the top of the cavity 4, and a fan 6 is arranged in the suction duct 5, and the fan 6 is connected with an air outlet 7 through a pipeline.

下面结合工作原理对本发明结构做进一步阐释。The structure of the present invention will be further explained below in conjunction with the working principle.

参看图2，冬季，在太阳照射下，光伏板将光能转化为电能供用户使用。室外空气通过光伏板底部的进风口流入空腔4，空腔4中的空气由于光伏板3工作产生大量热而温度升高，在风机6与热压的双重作用下空气上升，进入吸风管道5，然后通过出风口7送到室内各空间。该过程中，室外空气吸收光伏板产生的热量后，经通风系统进入室内，满足室内采暖和通风的需求，提高了室内空气质量，节约能源。Referring to Figure 2, in winter, under the sunlight, photovoltaic panels convert light energy into electricity for users to use. The outdoor air flows into the cavity 4 through the air inlet at the bottom of the photovoltaic panel. The air in the cavity 4 increases in temperature due to the work of the photovoltaic panel 3 and generates a lot of heat. Under the dual action of the fan 6 and the heat pressure, the air rises and enters the suction duct 5, and then send it to various indoor spaces through the air outlet 7. In this process, after the outdoor air absorbs the heat generated by the photovoltaic panels, it enters the room through the ventilation system to meet the needs of indoor heating and ventilation, improve the indoor air quality and save energy.

参看图3，夏季，当室外空气温度高于室内温度时，通风道5与空腔4连接处的阀门关闭，室外热空气从空腔4底部的进风口流入，从上部的出风口流出，热量不会进入室内。空腔4形成的通风间层，既有利于空气在流动过程中带走光伏板产生的热量，提高光伏板的发电效率，也使墙体达到隔热降温的目的。当室外空气温度低于室内温度时，打开通风道5上的旁通8，在风机6的作用下，将室外空气输送到室内。Referring to Figure 3, in summer, when the outdoor air temperature is higher than the indoor temperature, the valve at the connection between the ventilation duct 5 and the cavity 4 is closed, and the outdoor hot air flows in from the air inlet at the bottom of the cavity 4 and flows out from the upper air outlet. Will not enter the room. The ventilation interlayer formed by the cavity 4 is not only beneficial for the air to take away the heat generated by the photovoltaic panel during the flow process, improving the power generation efficiency of the photovoltaic panel, but also enabling the wall to achieve the purpose of heat insulation and cooling. When the outdoor air temperature is lower than the indoor temperature, the bypass 8 on the ventilation duct 5 is opened, and the outdoor air is transported into the room under the action of the fan 6 .
