摘　　要：运用κ-ε湍流模型和N点风口动量模型对某办公室空调的室内温度场和速度场进行了模拟,并利用经济指标对该气流组织进行了评价。利用多功能测量仪对办公人员呼吸区的空气温度和气流速度进行了测量。结果表明,计算所得的温度和速度分布与实际测量的数据基本一致,可为相关的实际空调工程设计提供理论依据和参考。The temperature and velocity field of an air conditioning office were similated with κ-εturbulence model and N-point momentum draught model,and use of economic index on this air distribution is evaluated.Air temperature and velocity of office workers breathing area were measured by multifunction admeasuring apparatus.The results show that the agreement between the calculation of temperature and velocity distribution and the practical measured data is quite well,it provide the theoretical basis and the reference for similar flows in a practical HVAC engineering design.
