以打印室为例,通过模拟置换通风、顶棚送风以及传统的中央空调送风形式,得到不同送风方式下的温度场、速度场和污染物浓度场,分析结果表明,置换通风方式并不适宜用在此类房间中(污染物密度比空气大的房间);在相同的能量消耗情况下,传统的中央空调送风形式不能提供良好的热环境,顶棚送风可以获得相对较好的室内空气环境。 Taking the printing room as an example, the temperature field, velocity field and pollutant concentration field under different blast modes are obtained by simulating displacement ventilation, roof blasting and the traditional form of air supply in central air conditioners. The analysis results show that the displacement ventilation mode is not Suitable for use in such rooms (rooms with a higher density of pollutants than air); the traditional form of central air-conditioning air supply does not provide a good thermal environment at the same energy consumption, and the ceiling air supply can achieve a relatively good indoor Air environment.
