摘　　要：应用CFD软件建立了送水泵房温度场的数学模型,通过对泵房典型的稳态阶段进行模拟与实测,证明所建立的模型是正确的。针对散热器的不同布置形式,通过模拟在开启1、4、5号泵组的工况下,当水泵机组开启台数较少且室外温度过低时,散热器布置在水泵层的方法仅能满足地面层人员活动的温度要求,而布置在走道层则可以满足两个层的人员活动要求。当水泵电机满负荷运行时,通过模拟计算,在满足采暖室内设计温度要求时,"可减少热指标"达到7.39W/m^2,节能率可达到12.85%,为此类泵房采暖系统的设计研究提供参考。The temperature field mathematical model of Water-pump which used heating system is simulated by CFD. Through the full-scale model simulation in the typical stationary phase and contrast with the measured data, the results indicate that the model is accurate. Through research and analysis, and combined with the actual situation, the radiators are well arranged in the walkway than un- derground. When these pumps are on full load operation, in can save energy at 7.39W/m2, overall energy-saving rate is 7.0%., also can provide references for the same tvoe of Water-Dump for heating strategy in winter.
