Description

A kind of green electric construction material

Technical field

The utility model is related to a kind of building materials fields, are specifically generation of electricity by new energy, photovoltaic application, green building material technology neck Domain more particularly to a kind of green electric construction material based on composite encapsulating material.

Background technology

As environmental protection pressure continues to increase, Green Development has become the theme of world economy.China builds conservation culture If mentioning unprecedented height with Green Development, building energy conservation is exactly to promote one of important measure of Green Development.

Since reform and opening-up, China's infrastructure construction and real estate investment sustainable growth, building energy consumption is in social total energy Accounting in consumption climbs up and up.Authoritative data shows that the end of the seventies in last century, China's building energy consumption only accounts for social total energy consumption 10%, and to the " 12th Five-Year Plan " end of term have risen to three the one-tenth of social total energy consumption it is more.It is reported that China's existing building and building More than 90% builds for high energy consumption, Energy Saving of Building under Heavy Responsibilities.

Green building just refers in the life cycle management of building, economize on resources to greatest extent (it is energy saving, save land, be water-saving, Save material), environmental protection and reduce pollute, for people provide it is healthy, applicable and it is efficient use space, with natural harmony symbiosis Building.Compared with traditional architecture, green building is average energy saving up to 58%, non-traditional water utilization rate up to 15%, recyclable material Expect utilization rate up to 7.7%.Green building is a new things, green building is risen to from traditional architecture, from not green building material Largely it is widely applied.

Photovoltaic generation with Integration of building is a trend of current green building and current distributed photovoltaic hair The important application form of electricity.According to the difference of the mounting means with Integration of building, photoelectricity architecture-integral can be divided into Additional (the Building attached of (Building integrated photovoltaics, abbreviation BIPV) and photoelectricity building Photovoltaics, abbreviation BAPV).

Photoelectricity architecture-integral is to implement Green Building Strategies, realizes the new technology of human kind sustainable development.Photoelectricity is built Integration is that Building technology is organically combined to the frontier for integrally, forming building with art and photovoltaic power generation technology.BIPV is not But there is peripheral structure, while can produce electricl energy and be used for building again.During developing photoelectricity architecture-integral, Traditional architecture is constructed to be merged with modern photovoltaic engineering technology and theory, and photovoltaic generating system is to build as carrier, with building It combines together, the technology of photovoltaic generation, required equipment will include the overall process of architectural design as Architectural Elements, make the sun Can system become building composition inalienable part, reach perfect adaptation with building rather than will building and photovoltaic It is glued together as two layers of skin.

The mounting means of Photovoltaic Building Integration be photovoltaic cell with watt, the construction materials such as brick, building materials, glass be compounded in one Rising becomes indivisible building element or construction material, photoelectricity tile roof, photoelectric curtain wall etc. is formed with this, to photovoltaic module It is more demanding.Photovoltaic module will not only meet the functional requirement of photovoltaic generation while also take into account the basic function requirement of building, The aesthetic feeling of building can also even be promoted.

And it is that photovoltaic building adds that China is most widely used at present, is with common photovoltaic module, it is in original building Upper installation does not substitute construction material or construction member, is mounted directly to roof or is attached to the photovoltaic system of metope.Common Photovoltaic module (solar module using tempered glass encapsulate) usually quality is larger, every square metre of weight reach 10 kilograms with On, in addition installation support construction, every square metre at least up to 12 kilograms or more, when it is applied in the fields such as top of building or metope In conjunction, higher requirement is proposed to the support construction of photovoltaic module, adds engineering construction, the cost of installation.Building and In family's roof installation process, there are weight weights, and installation labor intensity is big, performance difficulty；Some occasions are carried due to building bearing The limitation of lotus cannot install；Product appearance is single, is less susceptible to variation to adapt to different the shortcomings of building beautiful requirement.

BAPV will not increase the waterproof of building, the performance becalmed.Moreover, BAPV can increase building load, influence to build Overall effect.In addition, for building surface, also there is repeated construction in BAPV, serious waste construction material. Comparatively, BIPV is more intelligent, is following development trend and main solar power generation that we are pursued now System.

Therefore, those skilled in the art be directed to developing a kind of photoelectricity architecture-integral based on composite encapsulating material Green electric construction material.
