Heating some molecules, particularly large, biological molecules such as proteins or nucleic acids, will cause them to change shape or even to break up.
The air comes through the diffusers in much larger velocities and different temperatures than the ones tolerated in the space. Due to diffusion, the velocity and the temperature differences are gradually decreased until they reach the tolerable limits.
Then, the volume of air per linear meter diffuser grille or will vary from 20 to 200 minutes depending on the heat-transfer coefficient, the height of the wall, and infiltration rate. Throw the occupied zone air are closely linked. Both can be taken into account in the analysis of your specific requirements.
