以办公间为研究对象,在不同的气流组织形式下,运用CFD-Fluent14.0模拟软件对室内房间顶送下回、异侧上送下回、同侧上送下回及下送顶回四种典型气流组织形式进行模拟研究。通过比较分析不同气流组织形式下办公间内的流场、浓度场和速度场的数值模拟结果,找出比较合理的通风方式,以达到快速降低办公间内的甲醛含量的目的,为长期处于工作间内的人员提供一个具有良好空气品质的舒适环境。通过比较模拟的结果发现,同样的室内条件下,当送风方式为顶送下回时办公间内的空气质量为四种气流组织形式中最佳。
Taking the office as the research object, CFD-Fluent14.0 simulation software was used to send the indoor room to the top, the opposite side to send back, the same side to send back and send back to the top under the form of different airflow organization A typical air flow organizational form for simulation studies. By comparatively analyzing the numerical simulation results of flow field, concentration field and velocity field in different office buildings in the form of different airflow, the reasonable ventilation mode is found to achieve the goal of rapidly reducing the formaldehyde content in the office, The interiors provide a comfortable environment with good air quality. By comparing the simulation results, it is found that, under the same indoor conditions, the air quality in the office is the best among the four airflow patterns when the air supply mode is top-down.
