Description
Technical field
The invention belongs to solar electrical energy generation architecture-integral (being called for short BIPV) technical field, particularly a kind of double-layer ventilation formula exterior wall that utilizes forced ventilation to reduce the back panel of solar photovoltaic module temperature.
Background technology:
Solar energy resources is abundant, and the solar energy utilization is to alleviate a kind of effective way of energy-intensive, and wherein solar electrical energy generation architecture-integral (being called for short BIPV) is the main flow trend that current solar energy utilizes.Solar panel and building effectively are combined into one, and do not need additional space, and the energy of generation utilizes on the spot, has reduced conveying energy consumption.The combination of BIPV has multiple, photoelectricity roofing, photoelectricity exterior wall, photoelectric curtain wall, photoelectricity sunshade member etc.
Yet the generating efficiency of self has not only fallen in the fuel factor that produces in the solar panel power generation process, and makes building itself be subjected to strong heat radiation, has to adopt air-conditioning temperature-reducing, has increased the operation energy consumption of building.
Existing correlative study reduces the method for BIPV solar energy thermal effect, and most perhaps solar power system reclaims heat for the solar panel self structure increases cooling-part, the temperature of control solar panel.These researchs at 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 at 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 (indoor near building) is glass or the other materials of printing opacity, reserved cavity in the middle of double-deck, increase ventilation opening up and down, utilize " stack effect " or forced ventilation, take away the unnecessary heat of outer photoelectric curtain wall, reduce photoelectric curtain wall to the heat radiation influence of inner layer glass.If the employing forced ventilation can be utilized part photoelectric curtain wall generated energy, provide supply of electric power to ventilation fan.Above-mentioned patent has taken full advantage of the characteristics of BIPV, improves cell panel and building bonded block 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 be drained 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 installed in the position of south elevation or the thing facade wall between windows of building.This BIPV mode has been avoided the contradiction between photoelectric curtain wall and the indoor lighting, and is easier of architect or owner's acceptance.Solar panel temperature under the strong situation of daylight in summer rises to 70 ℃ ~ 100 ℃, is that the entity exterior wall also has thermal radiation effect significantly to the inboard.For head it off, the invention provides a kind of narrow passage double-layer ventilation external wall structure that utilizes photovoltaic generation.
Summary of the invention
The present invention has designed a kind of double-layer ventilation exterior wall that utilizes forced ventilation mode cools solar cell plate, technical scheme is: 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, skin is the solar panel of monolithic or polylith splicing, and internal layer is the building wall between windows.
A kind of narrow passage double-layer ventilation exterior wall that utilizes photovoltaic generation comprises solid wall 6 and the solar panel 1 that is fastened on solid wall 6 outsides by chemical anchor bolts 3, described solid wall 6 and the solar panel 1 middle cavity 5 of having reserved; Cavity 5 tops are provided with air outlet, and the air outlet place is equipped with out air-valve 7, and cavity 5 belows are provided with air intake, and the air intake place is equipped with air intake valve 8.
5 have installed temperature pick up 4 in the cavity, and the control end of temperature pick up 4 is connected to controller 9 temperature of monitoring is sent to controller 9.The output of controller 9 connects to be controlled out air-valve 7 and air intake valve 8 and controls out air-valve 7 and the opening and closing of air intake valve 8.
Part solar panel 1 is controller 9 and dc fan 10 power supplies.
The solar panel that solar panel 1 is composed in series for polysilicon, monocrystalline silicon, thin film amorphous silicon or multi-element compounds type battery chip.
The width of described cavity 5 is 50mm ~ 100mm.
Surpass 30 ℃ if non-heating season is measured temperature, controller is opened the air-valve of air intake and air outlet, opens dc fan, and under the driving force of blast, cold air enters cavity from air intake, and hot air is discharged from air outlet.Heating season air intake and air outlet air-valve Close All, form a greenhouse in the dc fan out of service, cavity, 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, between solar panel and entity exterior wall, reserve cavity, take away quantity of heat production in the solar panel power generation process by the dc fan forced ventilation, 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) radiation that has reduced skin gets heat, has reduced the building air conditioning operation energy consumption; (3) carry out forced ventilation by blower fan, guarantee cooling effect by controlled wind speed; (4) adopt dc fan, by the solar panel power supply, reduced the input of external power source, simple in structure; (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.
