内含集中热源空调房间内表面对流换热系数初探

Convective heat transfer coefficient analysis of inner wallsof an airconditioned room with a concentrated heat source

通过数值求解的方法，研究含集中内热源空调房间内壁面的对流换热系数的变化，并着重分析了送风方式、风口位置、送风量大小及热源强度等因素对该系数的影响及其变化规律．对在计算空调房间负荷时，取内壁面上对流换热器系数为定值的方法提出质疑．

The paper analyzes numerically the heat transfer coefficient distribution along the inner walls of an airconditioned room with a concentrated heat source.The facts,such as the ways of air supply,the locations of inlet and outlet,volume of air supply and so on,have an effect on the coefficient.It concludes that it is inappropriate to choose a fixed heat transfer coefficient for the inner walls when the load of an airconditioned room is calculated.
