Abstract:

In this paper,first,a physical model of an office was built. Then,based on the indoor zero equation turbulence model,a numerical simulation of the air distribution in the modeled office with air conditioning terminal device was carried out with AIRPAK3.0. Moreover,the effects of air supply temperature and velocity on the thermal comfort were analyzed,and the air supply parameters at the typical moments in one day were optimized,with the results being finally compared with the actual operation data. It is found that the air conditioning terminal device is of great energy-saving potential,and that,after the optimization of operation parameters,the theoretical cooling capacity of the terminal device in one day averagely reduces by 17%.

Key words: computational fluid dynamics, central air conditioning, energy saving, thermal comfort, air distribution
