【摘要】 以办公室为研究对象,采用数值仿真的方法,研究了地板辐射供冷加置换通风和顶板辐射供冷加置换通风在相同的室内负荷条件下,室内的温度及流场分布。结果表明,地板辐射供冷加置换通风系统的舒适性更好,而且其冷板表面结露的危险也比顶板辐射供冷加置换通风小。
【Abstract】 An office with combined air conditioning system of displacement ventilation and radiant cooling was studied by using numerical simulation.Indoor thermal environments were obtained and indoor vertical temperature distributions were given under different radiant cooling system forms.Results show that thermal comfort of radiant floor cooling and displacement system are better,and the risk of condensation is lower than that when chilled ceiling panel operates.
