Description
Technical field
The present invention relates to a kind of indoor sunshade cooling device, low-grade natural cooling source directly can be utilized significantly to reduce summer air conditioning load, belong to energy-saving building technology field.
Background technology
Along with the raising day by day that people require comfort level, the demand of HVAC increases fast, and from nineteen ninety-five by 2010, China's town-property air-conditioner owning amount sharply increases to 2.91 hundred million from 0.09 hundred million.The fast development of China's urbanization has also impelled public building area to increase substantially, and has reached about 83.5 hundred million m2 to 2012, and its air conditioning energy consumption is 1.82 hundred million tons of standard coals, and account for 26.4% of building total energy consumption, wherein high-grade power consumption is 4,900 hundred million kWh.
The general thermal resistance of printing opacity building enclosure is less, and directly through solar radiation, can obtain hot main source summer often.And glass fender structure is applied in modern architecture more and more, become one of high reason of air conditioning energy consumption.
Architectural shading is a kind of simple and effective passive type power-saving technology, can stop that sun good fortune is penetrated, and decreases and enters indoor heat.But the problems such as external sunshade also exists impact attractive in appearance, the easy breakage of building and clean and maintenance workload is large, never apply; Common internal sunshade still can make radiations heat energy enter indoor, can only delay to a certain degree and cut down solar gain, significantly can not reduce summer air conditioning load.
Low-grade energy is extensively present in the life production of people, the low-grade energy that can be used for summer cooling comprises water of river, lake and sea, by the cooling water that soil source heat exchanger obtains, the cooling water close to wet-bulb temperature obtained by direct evaporating-cooling and the cooling water etc. close to dew-point temperature obtained by indirect evaporating-cooling.But by the cooling water that low-grade energy obtains, temperature is higher, and the temperature difference between indoor air temperature is less, and more difficult being directly used in removes indoor heat.But in the position of the sunlight direct irradiations such as indoor sun-shading louver, temperature is often higher, the cooling water utilizing low-grade energy to obtain can take away the heat in these regions effectively.
Chinese patent literature (CN201310603631.8) proposes a kind of horizontal sector movable external shading device.Its energy-saving principle is similar to common external shading device, solar radiation can be blocked outside building.But these external shading devices can destroy the aesthetic property of elevation of building, and easily laying dust needs often cleaning, and will bear the destruction such as wind and weather, corrosion, and practicality is poor.
Chinese patent literature (CN201410180822.2) proposes the indoor abat vent adopting motor to drive puggaree.Although this patent proposes innovation from control, there is no difference from energy-conservation angle and common internal sunshade curtain.Common internal sunshade can not stop solar radiation to pass glass to enter indoor, just first heat is concentrated near abat vent, then reaches other positions indoor gradually.Glass has greenhouse effects, and shortwave solar radiation can pass through, and long-wave radiation is more difficult passes through, and is spread out of so the heat of indoor is more difficult by glass.Therefore, the energy-conserving action of internal sunshade is very limited, can only delay to a certain degree and cut down solar gain.
What Chinese patent literature (CN201010100502.3) proposed embeds in building enclosure by pipeline, the low-grade energy such as soil, cooling tower can be utilized directly to remove room conditioning load in summer.But its application is mainly body of wall, there is not the control method for glass fender structure.
Therefore, need a kind of technical scheme to remove efficiently and import indoor solar radiation heat into by glass fender structure.
