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.
Counter to, for a given diffuser size, air flow and Vr, the throw will decrease 10 cm for every meter increase in installation height when this exceeds 3 m. The throw is a function of air velocity, the reduction of which is proportional to the air quantity of the room that is drifted by the primary airstream.
