Experiments were performed in a climate chamber (L x W x H: 4.12 m x 4.2 m x 2.89 m) arranged as an office with 2 workstations (Fig. 1). The chamber was equipped with total volume mixing ventilation (MV), personalized ventilation (PV) on each desk and with a chilled ceiling (CC). The round movable panel was used as a PV diffuser because of high efficiency in delivering clean air to occupants at low turbulence intensity of the supplied personalised flow [27]. Three linear diffusers mounted at the centre of the ceiling were used for MV. Exhaust diffusers were located in the ceiling corners, as indicated in Fig. 1. Eighteen radiant cooling panels (1.19 m x 0.59 m) were built-in the suspended ceiling and covered 75% of its area.
