圆形断面净化空调机组相关问题的探讨
Discussion on air handling unit with circular section for cleaning air system
摘要：
建立了数学模型，对比分析了圆形断面和正方形断面空调机组的沿程阻力，表冷器、过滤器的断面风速和阻力，机组的隔声性能。结果表明，在相同条件下，圆形断面空调机组的沿程阻力可以降低11%，但是以多占用机房面积为代价的；表冷器、过滤器阻力明显增加；机组壁板的隔声效果较差。

Abstract：
Establishes the mathematical model and compares the frictional resistance, the sectional air speed and resistance of surface air coolers and filters, and sound insulation performance, between circular section and square section AHUs. The results show that the frictional resistance of a circular section AHU is 11% lower than that of a square section AHU at the costs of increased space requirement for the plant room, obviously increased resistance of the surface air coolers and filters and poorer sound insulation effects.
