In order to solve in the solar electrical energy generation process, temperature raises and to cause self generating efficient to reduce and to the problem of the heat radiation influence of architecture indoor, the utility model has designed a kind of double-layer ventilation exterior wall that utilizes natural ventilation system cools solar cell plate, building is installed solar photovoltaic cell panel towards sunny side (mostly being east elevation, south elevation and western facade) wall between windows position, form double-decker, outer solar panel for the polylith splicing, internal layer is the building wall between windows.
The utility model adopts following technical scheme:
A kind of wide-pass double-layer ventilation exterior wall that utilizes photovoltaic generation, solar panel 1, described solid wall 6 and the solar panel 1 middle cavity 5 of having reserved that it comprises solid wall 6 and is fastened on solid wall 6 outsides by chemical anchor bolts 3.The width control of cavity 5 is in 150 ~ 200mm, and cavity 5 tops are provided with air outlet, and air-valve 7 is installed out at the air outlet place, and cavity 5 belows are provided with air intake, and the air intake place is installed into air-valve 8.
5 have installed temperature pick up 4 in the cavity, and temperature pick up 4 ground inputs are connected to controller 9 temperature of monitoring is sent to controller 9.The control end of controller 9 with go out air-valve 7 and be connected the opening and closing of controlling out air-valve 7 and air intake valve 8 with air intake valve 8.
The square formation that solar panel 1 is made up of the splicing of polylith cell panel, the square formation vertical height is controlled at 8 ~ 10 meters; Leave 1 ~ 2 meter gap between two square formations, reduce the heat string wind phenomenon between the square formation.
It is controller 9 power supplies that the output of solar panel 1 connects controller 9.
The solar panel of solar panel 1 for adopting polysilicon, monocrystalline silicon, thin film amorphous silicon or multi-element compounds type battery chip to be composed in series.
Surpass 30 ℃ if non-heating season is measured temperature, controller is opened air intake and air outlet, forms stack effect in the cavity, under the driving force of hot pressing, cold air enters cavity from air intake, and temperature raises under the heat radiation of solar panel, and hot air is discharged from air outlet.Heating season air intake and air outlet air-valve Close All, form a greenhouse in the cavity, strengthen the heat-insulating property of building itself.
The BIPV mode that the utility model combines with the entity exterior wall at solar panel, between solar panel and entity exterior wall, reserve cavity, take away quantity of heat production in the solar panel power generation process by " stack effect ", reduce the thermoradiation efficiency to skin.The beneficial effects of the utility model (1) have reduced the solar panel operating temperature, have improved generating efficiency; (2) the mode cools solar cell plate of employing natural ventilation does not need electrically ventilating equipment, and the cooling procedure noenergy consumes; (3) the mode cools solar cell plate of employing natural ventilation does not need electrically ventilating equipment, has simplified system architecture, and construction install convenience does not need the follow-up maintenance maintenance work; (4) radiation that has reduced skin gets heat, has reduced the building air conditioning operation energy consumption; (5) reduced the surface temperature of skin, avoided the negative effect to indoor thermal comfort effect, improved indoor quality of life and improved operating efficiency.
