大跨度空间非等间距喷口送风空调设计方法
Design method of non-equidistant nozzle air supply air conditioning systems in large-span space
摘要：
针对大跨度空间负荷分布不均匀的情况,在传统射流公式法的基础上,提出了一种非等间距布置喷口的送风设计方案。结合某酒店多功能厅案例,阐述了如何根据房间负荷分布特点进行喷口的非等间距设计,并利用CFD软件对空调区温度场、速度场及热舒适性指标(PMV、PPD、DR(吹风感造成的不满意度))进行了模拟。结果表明,该方案取得了明显的改进效果,同时也验证了非等间距喷口送风设计方法的可行性。
Abstract：
In view of the uneven distribution of load in large-span space, based on the traditional jet formula method, an air supply design scheme of non-equidistant nozzles is proposed in this paper. Combined with the case of a hotel multi-function hall, how to design the non-equidistant nozzles according to the load distribution characteristics of the room is expounded, and the temperature field, velocity field and thermal comfort index (PMV, PPD, DR) of the air conditioning area are simulated by CFD software, and the results show that the scheme has achieved obvious improvement effect, and also verifies the feasibility of the non-equidistant nozzle air supply design method.
