1、摘要本设计为郑州某四层宾馆空调系统设计,该楼一层为商业用门面房,二层有一个会议室,其余为客房,三四层均为客房。此次设计的内容主要包括:各层房间的空调系统设计;卫生间排风系统设计;制冷机房设计。根据建筑物的结构、使用要求、环境条件等因素,设计中参照相关规范和工程实例,提出合理的空调系统设计方案,在创造舒适室内环境的同时,尽量降低能耗。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,比较各类型空调方式的优缺点,采用了风机盘管加新风系统的空气调节方
2、式;根据房间构造的不同采用了侧送和散流器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了风管和水管的尺寸,并进行了水力计算;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;冷、热、湿负荷;风机盘管加新风系统;冷却水系统;设备选型IIIAbstractThesubjectofthegraduationprojectistheair-conditioningdesignofahotelwithfourfloorinZhengzhou.Thefi
