Floor Cooling - Cfd Numerical Simulation Of Displacement Ventilation Air-conditioned Room

This paper introduces floor radiant cooling system and displacement ventilation system firstBasing on the two systems' advantages and disadvantages,people present the compound system.This compound system makes use of each system's strongpoints and obviates each system's weaknesses.The study of compound system is still nowadays underway. In order to advance people's understanding of it,this paper takes aim at exposing indoor environment using CFD numerical simulation.By analyzing the temperature and velocity fields of indoor airflow,this paper let people realize the compound system more precisely.Theoretical and experimental data both indicate that the compound system can provide not only comfortable but also economical environment which is superior to that of other air-conditioning systems.
