摘　　要：针对相同送风温度、送风速度,不同气流组织形式的几种模型,利用暖通空调专业模拟软件——Airpak模拟室内的速度场、温度场、CO2体积分数场和空气年龄,研究气流组织对室内空气品质和工作区内人体的舒适性的影响,并用能量利用系数指标对其设计效果进行评价.得出"在相同的送风温度和送风速度下,置换通风方式的空气品质最好,能量利用系数也最大"的结论,为室内空调气流组织优化设计及舒适性评价提供了依据.According to several models with the same supply air temperature and velocity and different airflow distribution, Airpak, which was the HVAC simulation software, was applied to numerically simulating the indoor velocity field, the temperature field, CO2 concentration field and the air age. The indoor air quality and human comfort in the work area under the influence of the air distribution was studied, and the energy utilization coefficient was used to evaluate design effect. The results showed that in the same supply air temperature and air velocity, displacement ventilation provides the best air quality, and energy utilization factor is also the largest. The conclusions provided the research basis for optimization design and comfort evaluation of airflow distribution in air- conditioning room.
