|•Qoz = Q1+Q2+Q3
|• Q1,2,3 are not easily, clearly estimated since it varies
according to its vertical, horizontal location, its distribution and
configuration of geometry.
|• Q3 appears in the forms of convection from the floor and walls.
|• There are two methodologies for Qoz
|• Macroscopic approach: starts
from Qtotal and try to make global weighting factors. It could
work for similar geometry but not universal.
|• Microscopic approach: starts
from individual heat source and try to make local weighting factors. It could
be more accurate but requires intensive investigation.
