【摘要】 地板送风房间回返气流所带回的由上至下的热转移,必将对下部冷负荷造成影响,文章针对下部有集中热源的地板送风空调房间,利用数值模拟结果,在前期得出的影响对流热转移量的因素的基础上,依次将各影响因素与对流热转移量之间进行数学关系分析,分别得出各因素与对流热转移量的数值关系,在此基础上通过曲线拟合得出对于地板送风房间对流热转移量的数学计算公式,为地板送风房间的冷负荷计算提供基础.更多还原

【Abstract】 Based on the gained factors which will influence the heat of transfer by convection of floor ventilation,the mathematical relations between heat of transfer by convection and the factors are analyzed successively using the results of numerical simulation.A calculation formula for heat of transfer by convection of floor ventilation room is gained using curve fitting,in order to provide some basis for cooling load calculation of floor ventilation room considering the convective heat transfer from non-occupied zone to occupied zone.更多还原
