Air, it's all around us We can't see it, but we sure can feel it It's like an invisible friend that's always there Let's talk about what air is made of Air is a mixture, not a pure substance It's got nitrogen, and boy, there's a wholelot of it In fact, about 78% of...
Accordingly, it is not necessary to perform a pre-cooling of the refrigerant or to prepare ice water. In addition, since single substance or mixture substances of pure water, anti-odor agent, anti- bacteria agent, anti-tick agent and aromatic agent or the like can be fed into the ...
The atmosphere in the building, as the biosphere around this planet, is a mixture of gases, mostly nitrogen and oxygen, and water vapour. There may be traces of other gases, particularly pollutants, which can be removed by filtration, absorption, or by ventilating the space. The water vapour...
Surface loads as high as 500 m3 m~2 h " 1 have been treated with good removal efficiency and low pressure drop for an optimized filter material mixture of compost and bark47 (refer to Figure 8). For more compact filter material, at the high surface loads desirable for highly diluted off...
The GAC filter’s removal performance of mixture gas phase contaminants was significantly reduced compared to that of single gases, since different compounds of a gas mixture would compete for the same free space on the carbon media. Among the different physical properties of indoor contaminant, ...

a natural mixture of gases, mainly nitrogen and oxygen, which makes up the earth’s atmosphere. The most important geological processes on the earth’s surface, as well as the formation of weather and climate, take place under the action of air and water. Air is the source of the oxygen...
