The three-dimensional hot film probe was first used in industrial ventilation to study the three-dimensional flow fields of local exhaust hoods. In order to know the effect of the operator in the flow field,a mannequin was put in front of the door to simulate an active person. Three important conclusions were obtained: 1. Near the edge of the door, the turbulent intensity was higher than at other places because of the edge effect, The farther from the opening, the more well-distributed flow field performed....

The three-dimensional hot film probe was first used in industrial ventilation to study the three-dimensional flow fields of local exhaust hoods. In order to know the effect of the operator in the flow field,a mannequin was put in front of the door to simulate an active person. Three important conclusions were obtained: 1. Near the edge of the door, the turbulent intensity was higher than at other places because of the edge effect, The farther from the opening, the more well-distributed flow field performed. 2. If there was a mannequin standing or sitting in front of the exhaust hood, great changes taking place in the flow field. Comparing with the free exhaust hood, the velocity closed to the mannequin became smaller, turbulent intensity become bigger and a big turbulent region was formed because of mannequin's hindering. 3. When the exhaust hood was installed on the working platform in front of the mannequin,the suction scope of the hood was declined because of the platform, so the velocity within the measured range became bigger.

作者首次将三维热膜探针应用于工业通风领域中侧吸罩三维流场的实验研究,并考虑到操作者对侧吸罩周围气流组织可能产生的干扰作用,采用三维着服模拟人代替实际操作者,对立姿、坐姿两种情况下的人体绕流三维流场进行了较详细的探讨和研究。研究结果表明:有模拟人存在时,由于人体模型的阻挡和绕流作用,使流场产生较大程度的改变,在人体模型正前方,流速变小,紊流强度增大;在人体模型绕流边界区域,流速变大。提示侧吸罩设计者采取有效措施以更好地保护操作者的身体健康。

With the gradual improvement of the people's living standard. People become more concerned with the indoor air quality problems, Test results showed that either for large office building with sealed windows or the casino ball room, restaurant, the meeting room, smoking room and the rooms in apartment house, the design and operation of the ventilating and Air - conditioning system or facilities equipped play an important role for controlling the indoor air quality in these rooms. Several; typical; cades were investigated which include: the case of high NH3 concentrations in the rooms of office building with sealed windows; the case of high concetrations of participate matter, co co2 in casino ball rooms, restaurants, meeting room, smoking room the indoor air pollution in rooms of apartment house due to pollutions released from gas appliances in kitchen and that from furniture' s and finishing. In order to keep good indoor air quality in these rooms, the following suggestions were put forward.1. Minimize the pollutants released from sautes, as possible; 2. Install local exhaust ventilatio facilities at the pollutant sources; 3. The ventilating and air conditioning system should be carefully designed and operated to guarantee providing enough fresh air into the room and a rational airflow pattern, That will prevent the supply air from being short - circulated and minimize the fresh air from being polluted in its flow path; 4. Choose fan (or systems) with energy conservation device to provide larger quantity of fresh (or diluting) air; S. Install air cleaner in these rooms to fitter out the dust particles, organism and odor from the recalculating air. Key words: Indoors air qualityVentilation air conditioning

随着人们生活水平的提高,室内空气质量日益引起人们的注意,无论是大型封闭式办公楼、还是配有空调设备的办公室、吸烟室、歌舞厅、餐厅,以及单元楼居室等,其室内空气质量的优劣和配套的通风空调系统的设计、使用密切相关。文中阐述了一些事例,如封闭式办公楼中氨浓度严重超标,会议室、歌舞厅、餐厅、吸烟室内可吸入颗粒物,CO、CO_2严重超标,居室的空气质量受厨房燃气和装饰建 筑材料的影响等。为保证有良好的室内空气,应从以下几方面着手:1.控制污染源的排放量;2.在污染物产生处设置局部排风;3.通风空调系统的设计,应提供足够的新风量,具有合理的气流组织,防止新鲜空气被污染;4.采用节能风机,提供较大的新风量和稀释空气量;5.在室内安装空气净化器,清除室内空气中的颗粒物和微生物等。
