Description

Low energy consumption integrated curtain wall building energy system and its operation method
Technical field
The present invention relates to energy-saving building technology fields, more particularly, to a kind of building for realizing curtain buildings low energy consumption target Energy resource system and its operation method.
Background technique
It is well known that building trade is actually one of maximum non-regeneration energy user, world's main economic is accounted for 40 or so the percent of body non-renewable energy consumption.Part power load of the photovoltaic curtain wall due to can solve building, Application in office building is gradually risen.But the characteristics of photovoltaic curtain wall building belongs to lightweight building enclosure because of its own, energy consumption one It is straight high, and solar battery due to being unable to get effective cooling seriously restricts its incident photon-to-electron conversion efficiency in photovoltaic curtain wall Promotion.In fact, and building enclosure be influence building energy consumption principal element, summer building cooling load, which mostlys come from, goes along with sb. to guard him The structure sun obtains hot, winter heating load and permeates mainly from building enclosure environment cooling capacity.Currently, heavy wall and lightweight light Volt curtain wall is used widely in office building.Currently, for the office building of north wall application heavy building enclosure, The major measure for reducing building load is exactly to use thermal insulation material.Although thermal insulation material is mature using as long as many decades, protect Adiabator also exposes problems in use, such as: a large amount of spaces, service life are occupied lower than the building longevity Life has fire safety evaluating hidden danger.And to south orientation widely apply photovoltaic curtain wall office building for, thermal insulation material application by It is then restricted, is then one of curtain-wall energy-saving measure relatively conventional at present using high-performance glass.But since glass belongs to gently Itself there is more serious heat-insulated and solar gain, so that indoor environment is easy to produce more in matter building enclosure The serious uncomfortable problem of heat, therefore building energy consumption and not yet in effect be reduced.In fact, formed from office building cooling and heating load From the point of view of angle, the solar radiation of summer southern side curtain wall, the photoelectric conversion waste heat of southern side photovoltaic curtain wall and winter north wall environment are cold Amount infiltration is to cause the higher principal element of Office Building Energy Consumption.But from the point of view of using energy source angle, they, which are belonged to, is not built Low-grade renewable energy efficiently using, on the spot and being widely present.In consideration of it, the present invention is enclosed for existing typical curtain wall The office building of protection structure design proposes integrated energy resource system solution.
Summary of the invention
In view of the technical drawbacks of the prior art, it is an object of the present invention to provide a kind of low energy consumption integrated curtain walls Building energy system makes full use of curtain buildings itself building enclosure and energy-storage system to collect, shift and store curtain buildings In the low-grade renewable energy that is widely present, can relax reducing curtain buildings whole year energy consumption, promoting office building Indoor Thermal While appropriate, the initial cost and operating cost of office building is greatly decreased.
It is a further object to provide a kind of operation method of low energy consumption integrated curtain wall building energy system, with Curtain buildings itself building enclosure and energy-storage system is made full use of to collect, shift and store the low product being widely present in curtain buildings Position renewable energy reduces energy consumption, energy saving.
