LoginThe paper will discuss design models for the air distribution system in an office with twopersons. The comparisons are made between mixing ventilation and displacement ventilationand they are based on a maximum velocity assumption and a restricted vertical temperaturegradient in the room. The comparison is extended by considering both the local discomfortcaused by draught rating (DR) and the percentage of dissatisfied due to the temperaturegradient (PD). The two different systems are finally evaluated by measuring the variation ofthe equivalent homogeneous temperature (EHT) at the manikin when it is exposed to theenvironment generated by the two systems.
