2、空气处理系统。 在冷负荷计算的基础上完成主机和风机盘管的选型, 并通过风量、 水量的计算确定风管 路和水管路的规格,并校核最不利环路的阻力和压头用以确定新风机和水泵。 依据相关的空调设计手册所提供的参数,进一步完成新风机组、水泵、热水机组等的选 型,并完成卫生热水这一块,从而将其反应在图纸上,最终完成整个空调系统设计。 关键词:关键词:中央空调,负荷,选型,管路设计 III A Design of a Hotels Central Air-conditioning System in NanChang Abstract With the development of science techn
3、ology and the increasing of living standard, the air-condition technology has been taken an abroad use, which built a healthy and comfort habitation for people. The designs included the system of a certain hotels center air-condition in NanChang. The whole air-condition section was plotted according
4、 to the different function-region, including: A. fan coils and the system of fresh air B. all-air system C. microtome-ceil air system The main-machine and fan coils choice were based on the calculation of cold-load. And through the numeration of blast volume and water flux, the standard of air duct
5、and water pipe was determined. The most disadvantage resistance and pressure of the loop-road were checked up to ensure the machine of fresh-air and water pump. According to the parameter which was offered by the correlate air-condition design handbook, the choice of fresh-air machine, water pump an
6、d the hot water machine was finished. Then the part of the sanitation-hot-water was performed. At last, the whole design was shown on the drawing.
