Abstract
In thermal environment where occupants stopover, the air supply jet easily dynamical changes due to some cross-flow interferences, influencing the dynamic human thermal comfort. RWI and PD are selected as the human dynamic thermal comfort indexes here. Based on the theory analysis on RWI and PD, the supply air temperature can be increased by improving the velocity in some extends. This will bring obvious energy saving of the air conditioning system. For example, based on RWI and PD within dynamic thermal comfort range, the supply air temperature could be 32°C with air velocity between 0.6-4 m/s. Experimental studies on the RWI and PD characteristics beneath the vent are developed, affected by the unstable cross-flow. According to the experimental results of typical testing points under the vent in vertical direction and horizontal direction at 1.5 m height, the values of RWI and PD are close to the comfort zone coupling with the dynamic cross-flow and the dynamic thermal comfort below the air conditioning vent is improved.
