1、河南理工大学本科毕业设计(论文)摘要摘要本设计为郑州某综合办公楼空调系统设计。该综合楼共五层,是一个以宾馆为主体附有餐饮的综合性商业建筑。本设计主要包括客房、两个大空间的中央空调系统以及制冷机房的设计。在设计中,通过查阅大量相关文献和设计规范,对设计中的部分未知参数进行了假定,并确定了室外计算参数和室内设计参数;完成了空调房间的冷、热、湿负荷和新风负荷的计算;根据空调房间的使用性质和大小,结合各种空调方式的优缺点,采用了风机盘管加新风和全空气一次回风系统两种不同的空气调节方式;根据房间构造的不同采用了侧送和百叶风口下送两种不同的送风方式;进行了冷冻水和冷却水系统设计;利用假定流速法确定
2、了风管和水管的尺寸,并进行了水力计算,其中水管的管径确定与风管有所不同,采用水管大流量、小流量确定水管管径;进行了制冷机房设计;根据样本,先后选择了风机盘管、空气处理机组、循环水泵、冷水机组、换热器、冷却塔等制冷空调设备;最后进行了管道保温和空调系统消声减振设计。关键词:空气调节;风机盘管加新风系统;全空气一次回风系统;制冷机房设计I河南理工大学本科毕业设计(论文)AbstractAbstractThisdesignisacomprehensiveofficebuildingairconditioningsystemdesignofZhengzhou. Atotaloffive-flo
