Theories And Experiments Research On How To Reduce The Window’s Energy Conservation Of Building Energy Saving Under The Climate Of Cold Region In Xinjiang

The research contents of this thesis takes he National Natural Science Foundation of China" Research on a new tectonic system of energy efficient residential building in Xinjiang "(project number is 50768009) of the research item of the natural science fund as foundation, combine region in Xinjiang to cross over strict cold region and cold region two weather areas in the region in the same weather area, among them, strict cold region in Xinjiang have endless strict and cold in winter, blazing hot dry decline water in summer rarely seen, the relative humidity is whole year round lower, air temperature year be worse, the day be greatly worse all and more, the nighttime temperature is away below in the daytime the temperature wait a special weather condition.That region building outer circle protects a structural heat preservation to still keep being that area building economy energy key, the outer circle protects the consume of window in the structure calories along with raise day by day of the economy energy standard is always construct to consume a calories comparison a quota more and more high.Aim at how to lower to lately set up with current building the window can consume of problem, this text from building the technique set out, make use of to transmit heat to learn, construct technique theories researches, such as hot work and building structure...etc. to lower the measure that the window transmits heat coefficient, put forward "night wall" and the concept of heat preservation Lian and lately set up a window to accept the sun in the daytime hot, the nighttime makes use of the target that"night wall" heat preservation attains building economy energy;The current building reformation changes the greatly actual circumstance of the cost Gao, resistance of window and can adopt heat preservation Lian a realization to lower the purpose that the window can consume.Adopt a theories calculation, test argument, numeral imitate analysis with solid example analysis etc. the means organically combine, get to round to protect a structure heat preservation a layer thickness increment economy energy a contribution rate to lower, but the window consume calories in the building the winter adopt warmly the ability always consume along with economy energy the up-trend of promote of target.Studied to establish a window to transmit heat coefficient variety regulation after different Lian and hot plate of the material heat preservation inside window;Different position constitution heat preservation Lian inside the window transmits heat coefficient variety regulation behind;Put forward the constitution"night wall" inside the window and the superior project of heat preservation curtain.Make use of the Dest-h can consume a residence building in Urumqi City of the calculation emulation: The other rounds to protect structure a constant premise a bottom, be a transmit heat of window coefficient to lower 10%, the building adopt warm can consume to lower about 5%.Combine lately sets up the night wall in the economy energy usage and the heat preservation Lian in the current building to expand economy energy performance, economic performance and possibility.
