Abstract- In this paper the experimental results of the measurements obtained testing two different configurations of air diffusion inside a simulated office room are reported. The overall aim of the work is to visualise the air velocity and temperature distributions in different sections of the climatised volume to understand if the right thermal comfort condition of the occupants are established. To reach the goal the research group of the Dipartimento di Energetica dell’Università di Ancona (D.E.A.), has designed and realised a series of laboratory devices and monitoring systems to test several air conditioning components and air diffusion configurations. In this way is possible to verify the right position of inlet and outlet diffusers, the flow rate and inlet air temperature to establish an uniform distribution of the air velocity. For this purpose vertical grills, round ceiling diffusers and floor linear diffusers are installedon the sides of a controlled room, where walls, floor and ceiling are modular to have whatever positions for the inlet and outlet diffusers. To record in steady state the values of the temperature and the air velocity on different vertical planes cutting the climatised volume an automated apparatus, designed and built with the component derived from the robotic technologies, has been utilised. The device consist of two guides, the first vertical and the other horizontal, on which moves a trolley
