Yet the generating efficiency of self, not only fallen in the fuel factor produced in the solar panel power generation process, and make building itself be subject to strong heat radiation, have to adopt air-conditioning temperature-reducing, increased the operation energy consumption of building.
Existing correlative study reduces the method for BIPV solar energy thermal effect, most for the solar panel self structure increases cooling-part, or solar power system recovery heat, controls the temperature of solar panel.These researchs, for solar cell and the characteristics that building combines, do not take full advantage of building as the carrier auxiliary temperature-reducing.
Special aeration-cooling design has been done for photoelectric curtain wall by some curtain wall producers, and declares and obtained corresponding patent.The principle of these patents is roughly the same, makes airtight photoelectric curtain wall into the open type curtain wall.Photoelectric curtain wall generally is designed to double-decker, the photoelectric curtain wall that skin combines for solar panel, internal layer (near Indoor environment) is glass or the other materials of printing opacity, in the middle of double-deck, reserved cavity, increase up and down ventilation opening, utilize " stack effect " or forced ventilation, take away the waste heat of outer photoelectric curtain wall, reduce the heat radiation impact of photoelectric curtain wall on inner layer glass.If the employing forced ventilation, can utilize part photoelectric curtain wall generated energy, provide supply of electric power to ventilation fan.Above-mentioned patent takes full advantage of the characteristics of BIPV, improves cell panel and Integration of building parts and structure and forms, and is worth using for reference.Weak point, in order to produce " stack effect ", the width of photoelectric curtain wall cavity and highly all strict demand must be arranged, could drain heat smoothly.And the forced ventilation mode, the control of wind speed also has requirement, and these patents all do not relate to.These patents have only realized the function of ventilating, but can't ensure the effect of ventilation.
A lot of BIPV engineerings more are inclined to the mode that adopts solar panel to combine with the entity exterior wall, solar panel are arranged on to the position of south elevation or the thing facade wall between windows of building.This BIPV mode, avoided the contradiction between photoelectric curtain wall and indoor lighting, more easily by architect or owner, accepted.Solar panel, in the situation that the strong temperature of daylight in summer rises to 70 ℃ ~ 100 ℃, is that the entity exterior wall also has thermal radiation effect significantly to inboard.In order to solve the heat radiation impact of cell panel generating on the entity exterior wall,, the invention provides a kind of wide-pass double-layer ventilation external wall structure that utilizes photovoltaic generation.
Summary of the invention
In order to solve in the solar electrical energy generation process, temperature raises and to cause the self generating Efficiency Decreasing and on the problem of the heat radiation impact of architecture indoor, the present invention 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 present invention adopts following technical scheme:
A kind of wide-pass double-layer ventilation exterior wall that utilizes photovoltaic generation, the solar panel 1 that it comprises solid wall 6 and is fastened on solid wall 6 outsides by chemical anchor bolts 3, described solid wall 6 and the middle cavity 5 of having reserved of solar panel 1.The width of cavity 5 is controlled in 150 ~ 200mm, and cavity 5 tops are provided with air outlet, and outlet valve 7 is installed 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.
In cavity, 5 have installed temperature pick up 4, 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 is connected the opening and closing of controlling outlet valve 7 and air inlet valve 8 with air inlet valve 8 with outlet valve 7.
The square formation that solar panel 1 is comprised of the splicing of polylith cell panel, the square formation vertical height is controlled at 8 ~ 10 meters; Between two square formations, leave the gap of 1 ~ 2 meter, reduce the heat string wind phenomenon between 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.
If non-heating season is measured temperature, surpass 30 ℃, controller is opened air intake and air outlet, in cavity, forms stack effect, 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, in cavity, form a greenhouse, strengthen the heat-insulating property of building itself.
The present invention is directed to the BIPV mode that solar panel combines with the entity exterior wall, reserved cavity between solar panel and entity exterior wall, by " stack effect ", take away the quantity of heat production in the solar panel power generation process, reduce the thermoradiation efficiency to skin.Beneficial effect of the present invention (1) has reduced the solar panel operating temperature, has improved generating efficiency; (2) adopt the mode cools solar cell plate of natural ventilation, do not need electrically ventilating equipment, the cooling procedure noenergy consumes; (3) adopt the mode cools solar cell plate of natural ventilation, do not need electrically ventilating equipment, simplified system architecture, construction install convenience, do not need the follow-up maintenance maintenance work; (4) radiation that has reduced skin obtains 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.
