Ventilation within a small cottage with a mansard - video 1
We placed a ventilator in the living room (blue box). Fresh new air enters the room from the above flowing upwards. The air then re-enters the ventilator from below.
It is difficult to evaluate the efficiency of a ventilation system. Time is the missing information. How much time is needed to renew the air in the apartment? Are there areas of the house where the stale air is tending to stagnate? We developed a post-processing visualization feature that responds to these needs.
This video makes use of 3 sections showing the color map of the concentration of fresh air which is transported and diffused in the house. Please notice the logarithmic scale of the concentration (in g/m^3)-The time lapse is a few hours.
