Description
Technical field
The present invention relates to a kind of job practices that the glass of existing building is carried out reducing energy consumption, belong to the energy-saving building technology field.
Background technology
Now in the existing about 43,000,000,000 square metres of buildings of China, the 99%th, the high energy consumption building, unit building area heating energy consumption is more than 3 times of developed country's new building.According to measuring and calculating,, will be present more than 3 times to the year two thousand twenty Chinese architecture energy consumption if do not take effective measures.Therefore, if existing building is not carried out reducing energy consumption, do not pay attention to the energy-saving design of new building now, will directly aggravate China's energy crisis.
In the existing about 43,000,000,000 square metres of high energy consumptions building of China, the energy consumption of curtain wall, glass of door and window has just accounted near half the.Analyze as the insider, the key of building energy conservation is that curtain wall, glass of door and window are energy-conservation.Therefore, existing building door and window and cladding glass being carried out reducing energy consumption, is the objective requirement of China's energy situation, also is the inexorable trend of market development.
The existing building reducing energy consumption, this part energy-saving potential is maximum, but it is relatively large to excavate difficulty.The emphasis of building energy-saving renovation is a public building, and the glass window wherein and the reducing energy consumption of curtain wall then are the keys of building energy conservation.Comprehensive reducing energy consumption with Shanghai Jin Mao Tower curtain wall is an example below, and prior art is set forth.
The Shanghai Jin Mao Tower was built in 1999, about 100,000 square metres of the curtain wall gross area.Mansion is high 420.5 meters, and underground 3 layers, 88 layers on the ground, more than 29.2 ten thousand square metre of overall floorage.Jin Mao Tower main building 3-50 layer is an office occupancy, and the 53-87 layer is ultra five-star hotel, and 88 layers are the layer of going sightseeing, and annex is multifunctional equipments such as finance, commerce, service, health and happiness., stand Jin Mao Tower at river bank, Huangpu, be the symbol of Pudong's reform and opening-up.But few people can expect, this building super highrise building is not only the minimum building, a building of China's unit area energy consumption, also are the maximum commercial buildings of China's energy consumption simultaneously.The comprehensive modernized building of such diverse in function; Its actual operation energy consumption is quite high; The annual energy spending of Jin Mao Tower is up to more than 4,000 ten thousand yuan, and every day, only three kinds of disposable energy costs such as water, electricity, natural gas will more than 13 ten thousand yuan, and the highest one day of summer, expense was above 1,000,000 yuan.In nearly 300,000 square metres of this building building area; 1.5 ten thousand people working is arranged every day, go sightseeing and life; Circulation of air and changes in temperature are regulated in the totally enclosed building, lean on the air-conditioning of a power up to 28000 kilowatts entirely, are equivalent to install at Jin Mao Tower the power summation of more than 9000 general domestic air conditioning.It is reported that Shanghai City capital construction commission requires Jin Mao Tower to carry out energy-conservation rectification, reason is in area, whole Lujiazui; Jin Mao Tower has become maximum electric-tiger; Year power consumption is surprising, to comprehensive reducing energy consumption of Jin Mao Tower curtain wall, will reduce the regional power consumption in Lujiazui; Improve the present situation of intra-building air conditioner refrigerating poor effect, promote rent and sale, the tourism popularity of this building landmark building.
The way of the glass energy-saving transformation in the existing building has only three kinds of selections at present: the one, and original glass is changed energy-saving glass; The 2nd, stick film for building to original glass; The 3rd, the inboard installs vacuum glass additional.
What the Jin Mao Tower curtain wall used is 8+12A+8 heat reflection hollow glass, Coefficient K value=3.0W/ (m
2K).
One, change the LOW-E hollow glass: glass Coefficient K value=1.8, heat-insulating property increases, but Jin Mao Tower is the outer stainless unit type curtain wall of decorating, it is also more bothersome than new installation to change glass, no feasibility.
Two, give original adhering film to glass: thermal isolation film class is divided into thermal reflecting coating and low-radiation film, and thermal reflecting coating (claiming solar control film again) can keep interior temperature can not raise too much in summer; Low-radiation film (claiming the LOW-E film again) uses the positive effect that can play heat preservation energy-saving in the cold district heating building.Shanghai is area cold in winter and hot in summer, and the heat insulation of summer considered in the existing consideration of building energy-saving renovation insulation in winter again.So, paste thermal reflecting coating at the mansion glass outer surface, original glass is the heat reflection hollow glass, pastes one deck thermal reflecting coating again, has both influenced the light transmittance of glass, to heat-insulating property improve also few; Paste low-radiation film in the mansion interior surfaces of glass, winter, heat-insulating property increased, but it does not have effectively iris action to far infrared rays, and summer, heat-blocking action was not obvious, so should not use this film in Shanghai.
Three, the inboard installs vacuum glass additional: Coefficient K value=1.2, and thermal transmittance improves bigger, but vacuum glass costs an arm and a leg immature, the unstable properties of technology.
How comprehensive reducing energy consumption of Jin Mao Tower curtain wall this carry out, and do not discuss so far and confirm.
In sum, also there is not a kind of job practices of effectively glass of existing building being carried out reducing energy consumption at present.
