Double heterojunction efficient film photovoltaic electric, hot combined supply apparatusTechnical field: the present invention relates to a kind of by the photovoltaic generation function of distributed roof photovoltaic micro-system and the integrated novel energy-conserving product of roof solar water heater function.
Background technology: at present roof photovoltaic generating system is all independently distributed micro-system array substantially in the world.The solar water heater that present roof is installed also is all the hot water apparatus of functional independence.Along with development and the utilization of regenerative resource, the confined space and the limited area on following roof will be subject to very large challenge.The present invention is exactly under such background, because high power concentrator penetrates the high temperature produced on copper indium diselenide (CGSe), Copper Indium Gallium Selenide (C1GS) double heterostructure cells sheet, utilize low boiling heat conductive medium circulation heat absorption, exothermic technology, solar battery sheet surface temperature can be made to reduce, again for water heater provides continual thermal source.By above-mentioned two kinds of function i ntegration one, electric, hot alliance, takes up space and reduces, cost-saving.The module of this electricity, hot combined supply apparatus can independently use, also can according to the needs of power consumption composition also, string system.
Summary of the invention: the present invention is primarily of the integrated luminous energy module of light-focusing type; Thermal storage water tank; Cold and hot temperature-difference circulation pump and controller three part composition.
For realizing photovoltaic power supply and integrated with the cost-saving object of luminous energy heat supply, technical scheme of the present invention is point two parts; I.e. outdoor roof power generation part and indoor heating part.Outdoor section comprises the integrated luminous energy module of light-focusing type and heat conductive medium heat transfer thereof; Indoor section comprises thermal storage water tank, the electrical installation etc. of heat exchanger and pipeline and temperature-difference circulation pump and control device and photovoltaic generation.
After the heat conductive medium pipeline of light-focusing type integrated luminous energy module one end is connected to each other, the one end with heat exchange connects; The pipeline of the other end of luminous energy module connects with circulation delivery side of pump; The input of pump connects with one end of heat exchange, and medium circuit is linked to be enclosed circulation network.Heat exchanger is placed in water tank, and water tank arranges thermometric indicating instrument.Hot water discharge pipe upper end in water tank is provided with electric heating temperature compensator and connects manual water temperature by-pass cock by the road; Water tank enters cold water switch device automatically built with water tank, and often opens cooling water inlet water pipe and is connected.
Photovoltaic efficiency of the present invention is high, and electric, hot alliance cost is low, takes up space little, is the product that roof energy supplying system is the most rising from now on.
