Evaluation And Numerical Simulation For Indoor Air Quality Of An Underground Emporium In Harbin

With the improving of the standard of our living, the source and variety of indoor contaminations increases increasingly. At the same time, the increase of degree of airproofing of the building makes chroma of indoor contamination thicker. All of them cause the indoor air quality running down. Now indoor air quality gradually become mostly contradiction of indoor environment, hotspot of appellate, and one of focus that all world pay attention to. People realize the significance and stringency of solving it. Finished work is as followed.Contaminations infecting indoor air quality are introduced, including formaldehyde, volatile organically, carbon monoxide, carbon dioxide, dust, radon, bacillus, temperature and humidity. The relation among contaminations and human's health is introduced.One of underground emporium in Harbin was test for indoor air quality, including formaldehyde, volatile organically, carbon monoxide, carbon dioxide, dust, radon, bacillus, temperature and humidity. And the test result is tidied. The test result is evaluated by means of different kinds of indoor air quality evaluation methods and theories, the methods of extensional evaluation, grey assessment, fuzzy judgment, integrated exponent are involved. Making use of those methods and theories we evaluate the date objectively, And Making use of in acceptable rate and grey assessment we evaluate the tabulation subjectively. Just compare these evaluation methods. Namely, the method of fuzzy judgment is nicer.Look into this underground emporium, find typical room, model with numerical simulation software with κ-ε and 'simple', and simulate on standard, different height girder, different velocity of blowing and difference in temperature conditions. Moreover, the outcome is analyzed.The instruments and measures at advancing air quality are summarized.
