Description

The photovoltaic and photothermal integral unit
Technical field
The present invention relates to a kind of integrated unit that utilizes solar power generation and hot-water supply, especially a kind of when utilizing solar energy to produce the high-grade electric energy, the integrated unit of temperature at the hot water more than 60 ℃ can be provided again.
Background technology
In a lot of occasions, both needed electricity to need hot water, but urban distribution network and gas ductwork all do not lay yet, the photovoltaic and photothermal solar technology addresses this problem.
The technology that two kinds of photovoltaic and photothermal solars are arranged at present, usually.A kind of is the heat that the water pipe of pasting metal material on the solar cell opaco glass substrate discharges when absorbing solar cell power generation, the water among the heating pipe; Also having a kind of is that heat-absorbing material is placed in a distance behind solar panel, absorbs the radiant heat transfer of solar energy electroplax, thereby adds hot water.
In the first method, the solar battery glass substrate is a difficult problem with combining of metal material water pipe always, the method for not properly settling, and just absorb the heat that solar cell distributes, the little temperature of heat is also not high enough, does not often reach domestic hot-water's needs of people.Second method mainly is the radiant heat transfer that relies between solar panel and the heat-absorbing material plate, and the heat conduction amount in the first method that its radiant heat transfer amount compares is lower, so the water temperature of this method is not high yet, generally below 45 degrees centigrade, the heat efficiency is also lower.
Summary of the invention
The present invention will provide a kind of photovoltaic and photothermal integral unit, when producing the high-grade electric energy, provides the hot water that satisfies people's living needs of higher temperature.
For achieving the above object, the technical solution used in the present invention is: a kind of photovoltaic and photothermal integral unit, comprise water tank, face glass, the solar cell piece of encapsulation, glass substrate, be characterized in: the solar cell piece that lays one group of encapsulation between face glass and the glass substrate, and leave the gap between the solar cell piece of encapsulation, lay the heat-absorbing material layer below the glass plate substrate, bury the hot-water line of several connection water tanks in the heat-absorbing material layer underground, connect by cold water pipe between the hot-water line, cold water pipe connects water tank.
Cold water pipe is positioned at outside the heat-absorbing material layer; Be provided with fixed support below the water tank.
The invention has the beneficial effects as follows:
Innovative point of the present invention is one whole solar photovoltaic cell panel compared with in the past, the present invention has adopted the solar-energy photo-voltaic cell gross area of encapsulation only to account for the part of glass substrate, some area is used for throwing the sunlight direct projection and absorbs the heat that sun direct projection brings to heat-absorbing material, the heat that produces when absorbing material also absorbs the generating of solar-energy photo-voltaic cell piece simultaneously, not only improved the solar energy utilization ratio of system, also increased the power that adds hot water, improve the hot water temperature simultaneously, can satisfy domestic hot-water user's needs fully.
Therefore, the present invention can be in the solar cell normal power generation, the heat that produces when absorbing solar cell power generation by sun direct projection heat-absorbing material and heat-absorbing material, and the water among the heating pipe provides the hot water that can satisfy the demand of higher temperature for people.
Description of drawings
Fig. 1 is a structural front view of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As Fig. 1, shown in 2, photovoltaic and photothermal integral unit of the present invention comprises water tank 1, face glass 2, the solar cell piece 3 of encapsulation, glass substrate 4, heat-absorbing material layer 5, cold water pipe 6, support 7, hot-water line 8.
The gapped of solar cell piece 3 of encapsulation is placed between face glass 2 and the glass substrate 4, solar cell only accounts for the part of glass plate area, below solar battery glass base board 4, lay heat-absorbing material layer 5, hot-water line 8 is embedded in the heat-absorbing material layer 5, the water that is heated by heat-absorbing material is flowed to water tank 1 by the buoyancy that density contrast produces by hot-water line 8, cold water pipe 6 is not embedded in the heat-absorbing material layer 5, and the water at low temperature in the water tank 1 is flowed out by cold water pipe 6.Water is continuous natural circulation heating between hot-water line 8, water tank 1, cold water pipe 6.
Operation principle of the present invention is: the solar cell piece produces high-grade electric energy under irradiation of sunlight.Simultaneously, solar cell can produce heat in normal power generation, and these heats are attached to base heat-absorbing material on glass and absorb; And big gap is arranged between the solar cell piece, and the sun can see through the direct projection heat-absorbing material, and heat-absorbing material absorbs the heat in the sunlight; By the absorption to two kinds of source heats, system provides enough heats to come water among the heating pipe, thereby obtains temperature at the hot water more than 60 ℃.So the present invention can provide high-grade electric energy and the hot water more than 60 ℃ simultaneously, satisfy people's needs.There not being electrical network to carry electricity, there is not the area of fuel gas transportation pipeline delivery of fuel gas, use the present invention, both can obtain high-grade electric energy, also can obtain the hot water of high enough temp simultaneously, satisfy the needs of productive life.
As shown in Figure 1, the present invention when daily electricity consumption is provided, provides temperature at the hot water more than 60 ℃ in the application in Shanghai University Of Electric Power building.
The design panel gross area of the present invention is about about two square metres.Collocation operational version ratio with the photo-thermal unit of one one square metre photovoltaic unit and one square metre, the photovoltaic efficiency height of the photovoltaic unit of the present invention than one square metre, since the northern heat-absorbing material good heat dissipation effect of photovoltaic cell of the present invention, the generating efficiency height; The photo-thermal power generation efficient height of the photo-thermal unit of the present invention than one square metre because heat-absorbing material of the present invention not only absorbs the heat of sun direct projection, also absorbs the heat in solar cell the north, photo-thermal efficient height.
