Experimental Analysis of Thermal Comfort in an Air Conditioned Open Space Office

Experimental analysis of thermal comfort in an open plan office has been presented in the paper. The office of interest is air conditioned by two parallel ceiling air terminal devices (ATDs). With the aim of mathematical description of the main characteristics of turbulent wall jets produced by the ATDs, a set of experimental measurements was carried out using the laser-Doppler-anemometer (LDA) method. Velocity profiles in the jets, axial velocity decay and other relevant jet characteristics were investigated for three distances between the ATDs and three fan speeds. For all nine cases, in the second phase of the measurements temperature and velocity fields within the occupied zone were determined and thermal comfort evaluated. The measurements were carried out in a full-scale test room at the Faculty of Engineering University of Rijeka.
