A kind of ventilating glass curtain wall and method of work thereof
Technical field
The condensed water of double-layered glass facade passage of heat interlayer sunshade of the present invention relates to be applied to ventilate reclaims sunshading technology in the middle of the slight irrigation natural plants, relates to the technical field of building energy conservation and utilization of new energy resources.
Background technology
Because curtain wall is penetrating attractive in appearance, have distinct epoch and technology breath, from eighties of last century second half so far, the application in office building all over the world is day by day fashionable.Meanwhile, the query of aspects such as the high energy consumption that glass-wall building brought, light pollution, improper ventilation also be can be heard without end.Especially at China Xia Redong cryogenic region, its climate characteristic has determined existing glass-wall building major part all to become the synonym of high energy consumption.In order to remedy the shortcoming of conventional monolayers glass-wall building, in recent years, the domestic ventilation double-layered glass facade system that introduced.Ventilation double-layer curtain wall system is developed by passive solar house, generally form by two-layer transparent space enclosing structure, air chamber as air duct is divided into inside and outside two parts to space enclosing structure, at different outdoor climate conditions, realize functions such as ventilation, cooling or accumulation of heat by rational ventilation tissue design, so, also be referred to as " epidermis of acclimatization variation " or " can breathe curtain wall ".Since 21st century, selected such system in a lot of reconstructions of Xia Redong cryogenic region and newly-built office building.Yet, use discovery by reality, in summer, the temperature drift in the double-layered glass facade passage utilizes the mechanical ventilation cool effect not remarkable merely.
With respect to position of window, the sunshade mode can be divided into three types of external sunshade, internal sunshade and middle sunshades according to the sunshade member.Divide from the gimmick and the making of sunshade design, can be divided into the simple and easy sunshade of building (as: building mutual sunshade, building) again, build three types of additional member sunshade, greening sunshades from sunshade.The obviously too late external sunshade of the sunshading and heat-insulating effect of internal sunshade, but because external sunshade will bear outdoor comparatively abominable natural conditions, the intensity of having relatively high expectations, rigidity and activity performance, and be inconvenient to go along with sb. to guard him and manage, so a lot of restrictions have been subjected in actual use.What ventilation double-layered glass facade employing at present was more is the interlayer sunshade, and sun shading material is based on blind.During common sun shading material external sunshade, most solar radiation will be reflected back toward space outerpace, a small amount of seeing through in solar protection devices and the glass inlet chamber, also have few part to be absorbed by sun shading material and device, make the solar protection devices temperature raise, mode with convection current and radiation continues to space, indoor and outdoor distribute heat, so, although external sunshade has been blocked in most solar radiant heat outdoor, but increased the burden of outdoor environment, problems such as urban heat land effect, global warming are aggravated thereupon.During common sun shading material internal sunshade, most solar radiation has penetrated in the glass inlet chamber, although having the part solar radiation to be seen through glass by internal sunshade reflection back gets back to outdoor, but the solar radiation that major part sees through is by solar protection devices, absorptions such as glass, solar protection devices, after the glass equitemperature raises, heat has entered into indoor in the mode of convection current, add the solar radiation heat that sees through glass and solar protection devices, then having the closely solar radiation of half to see through the internal sunshade system has entered into indoor, finally, will be converted into the room conditioning load through after a while conversion and delay.So, no matter be the sunshade of which kind of form, the function that common sun shading material can be realized mainly is reflection and projection, the part that self absorbs seldom, even self absorbed part solar radiation heat, after treating that the sun shading material temperature raises, this part heat still can continue to feed back to the indoor or outdoors environment with the form of convection current and radiation.That is to say, conventional sun shading material only is that the solar radiation heat is postponed to be converted into indoor refrigeration duty, or feed back to the outdoor environment space, even if may produce certain energy-saving effect, but also only be energy consumption statistic at building self, though building self energy consumption has reduced, and can cause problems such as urban heat land effect, global warming, be difficult to realize real energy-conservation.Avoid this situation, one of efficient ways is exactly the plant landscape sunshade.
The difference of greening sunshade and other sunshade modes just is that its energy flows to.Vegetation is biological energy source by photosynthesis with conversion of solar energy, and transpiration makes the temperature maintenance of blade itself again within lower fluctuation range, thereby, cut off the secondary of energy and propagated.And plant in this course, can also absorb the energy in the surrounding environment, thereby reduced local ambient temperature, causes the benign cycle utilization of energy.In this process of utilizing the greening sunshade, the cardinal principle of its sunshade is absorption and the transformation of vegetable curtain solar protection devices self to solar radiant heat, be to be biomass energy with conversion of solar energy, and the temperature of heat absorption back vegetable curtain does not raise, thereby make that feeding back to space outerpace significantly reduces with the solar radiant heat that enters the interior space, energy-conservation from realizing in essence.Thereby realize the harmonious development of Man ﹠ Nature.Therefore, the most effective sunshade mode of double-layered glass facade building is exactly the sunshade of vegetable curtain interlayer, should make full use of the energy transforming principle of greening sunshade, strengthens the performance of greening sunshade.
The general employing of traditional greening sunshade climbed up by holding on to/climbed or hanging class plant, all need support bracket fastened support, plantation load and anti-drainage problem are difficult to solve, and face the fallen leaves collection and be difficult to manually operated problem, and all especially multi-users of insect protected problem are difficult to accept the major reason of vertical greening external sunshade, also make it be difficult to use in highrise building.Sunglo pineapple class unrooted no-soil plant can be woven into the wire curtain of any density, random length, and heat-resisting, cold-resistant, drought-enduring, moisture-proof, be difficult for infested, poor growth, evergreen all the year round, the advantage that had both had the plant sunshade, can avoid the defective of conventional greening sunshade again, broken the bottleneck of vertical greening sunshade, for broad application prospect has been opened up in the application of plant sunshade in building glass-wall building especially.
Simultaneously, the summer air-conditioning system generally can produce a large amount of condensed waters, and one air-conditioning can be discharged 1 liter of condensed water in per two hours when normal temperature refrigeration or dehumidifying work.With summer 35 ℃ of outdoor environment temperatures be example, setting the room conditioning temperature is 28 ℃, at this moment, condensate temperature is generally low more than 10 ℃ than environment temperature, and simultaneously, the pH value of air conditioner condensate water is neutral, water quality is better, very suitablely grows flower, breeds fish, and is used for potted landscape and cultures and also be difficult for alkali.At present, the basic skills of handling condensed water is directly with its discharging or recovery section sensible heat only, has caused the waste of the energy, if directly be disposed to outdoorly, can pollute wall especially, influences the outward appearance of building, makes troubles to the pedestrian.Because becoming this phase transition process of gaseous state by the liquid state evaporation, water will absorb a large amount of heats, so be necessary sensible heat in the condensed water and latent heat are recycled.
