The problem – determine how fast air mass flows and what is the convective heat exchange in a building which has a complicated structure: glass atrium is located on the roof.
In this case an accurate building model was designed to calculate this: all walls and partitions were designed, as well as prescribed thermo-physical properties. Experts modeled air mass of the building.
This calculation is the solution for the following: how to place heaters / air conditioners; what is the heating temperature of air masses indoors. The solution – application of additional heat devices to maintain normal temperature indoors during winter.
These calculations could define the full circulation of indoor air masses. Calculation results indicated the possible air circulation trajectory, air temperature changes, variation of air mass heating, as well as exactly determine the original freezing places in a building during winter.
