Description
technical field:
the present invention relates to a kind of method of building the Driven by Solar Energy ventilating air-conditioning system ventilation of hollow-core construction.
background technology:
at present with solar energy, reduce the application of consumption of non-renewable energy resources very extensive, but for restricted high level and the high-rise building of windowing, apply this resource difficulty very large.Solar energy is the clean energy resource that the mankind depend on for existence, and applied solar energy can reduce the consumption of non-renewable energy resources, reduces carbon emission simultaneously, reduces the impact of greenhouse effects.The 2013 > > reports of International Energy Agency (IEA) issue < < world energy outlook claim 2035, take wind energy and photovoltaic as main intermittent power supply accounting 45%.System research to regenerative resource Emission Reduction Potential shows, the contribution to building carbon emission reduction of solar energy optical-thermal photovoltaic application and solar energy, from 2010～the year two thousand thirty, can reach 1-5TtC/a～15-30 TtC/a.
research constantly developmental research and application at present by solar energy for building nature ventilation, gravity-flow ventilation is a kind of energy-conservation, green technology measure that can improve indoor thermal comfort and improve indoor air quality, gravity-flow ventilation utilizes blast, utilizes hot pressing, blast and several forms such as hot pressing combines realizing in principle, modern humans is that comprehensive utilization indoor and outdoor condition realizes to the utilization of gravity-flow ventilation, as according to building surrounding environment, architectural composition, Architectural Construction, solar radiation, weather, indoor thermal source etc., organize and induce gravity-flow ventilation.Meanwhile, in Architectural Construction, the optimal design by members such as Zhongting, double-layer curtain wall, door and window, roofs, realizes good effect of natural ventilation.In various Natural Ventilation Technology In One Greens, double-layered glass facade is a kind of comparatively advanced technology, for restricted high level and the high-rise building of windowing, this technology is a kind of conservation measures of making to measure, between the double glazing of double-layered glass facade, leave larger space, be often called as " breathing curtain wall ".In the winter time, double glazing interlayer forms sun glasshouse, improves architectural exterior-protecting construction surface temperature; In summer, can utilize stack effect to ventilate in layer.Simulation of air flow result shows, this structure can greatly reduce building cooling load, improves gravity-flow ventilation efficiency.Zhang Huimin to Architectural Atrium neutral plane analyze, think that Zhongting and neutral plane height increase along with the increase of sky window ara, but keep away Zhongting and skylight are unavoidably set under construction.A kind of Natural Ventilation Technology In One Green that combines the auxiliary stack effect of solar energy and intelligent curtain wall construction is also explored by the team of Matthew Herman.
under the dual-pressure of energy scarcity and ecological deterioration, building air conditioning still has its irreplaceable importance, yet air conditioning energy consumption accounts for 30% of building energy consumption according to statistics, and the proportion of air conditioning energy consumption strengthens year by year, conventional air-conditioning energy consumption is large, large to ambient influnence, be badly in need of finding a kind of novel air conditioning mode and substitute conventional air-conditioning, alleviate the pressure of energy consumption and environment.
in the engineering application of hollow brick building, hollow brick has saving material, build efficiency by laying bricks or stones high, insulation and permeability are good etc., as new materials for wall, researcher both domestic and external did a lot of tests to various brickworks, wherein the experiment of the axial compressive strength of hollow brick was shown to the axial compressive strength of brickwork equals or a little more than the masonry of same label solid brick.Reason is that the size of hollow brick is generally larger, thicker than solid brick, and in measure-alike resistance to compression test specimen, the mortar joint of hollow brick test specimen is few, and mortar joint is little on the impact of the impact comparison solid brick of test specimen intensity.Therefore brickwork compression strength will be higher than solid brick; The research of the shearing strength of brickwork is shown to its shearing strength equals or a little more than solid brick shear strength of masonry.This is because the surface of hollow brick is generally coarse than solid brick, more tight with mortar combination, and the mortar in brickwork enters in people's hollow brick cavity, form the pin key of inserting people's hollow brick, the shearing strength of brickwork is improved, and the G.SCHELLBACH of Germany thinks: when hole ratio is no more than 35%, hollow brick wall intensity is higher, but once hole ratio, reach 40%～55%, the intensity of hollow brick wall will reduce.
driven by Solar Energy multifunction natural ventilation and air conditioning system design studies based on building hollow-core construction is significant, on the Research foundation of BIPV, theoretical in conjunction with the hot pressing of gravity-flow ventilation stack effect, utilize the air space of building hollow-core construction as vent passages, energy-conservation, material-saving; Select clean solar energy as drive energy, reduce the discharge capacity of conventional energy resource CO2 and other pollutant.Whole system can substitute the operation of air-conditioning unit, improves indoor air quality and thermal comfort, reduces air conditioning energy consumption and carbon emission.
