1、河南理工大学本科毕业设计(论文)摘要摘要本工程为郑州市某办公楼的空调系统设计。该建筑层数为五层,每层都用于办公。根据建筑的使用功能,初步选定空调的系统形式,此办公楼采用风机盘管加独立新风系统。风机盘管为吊顶卧式暗装,气流组织为上送上回,送、回风均采用单层百叶风口,新风由新风机组集中处理后供到各个空调房间,新风处理到室内空气焓值,不承担室内冷负荷。夏季冷负荷计算采用谐波反应法,冬季热负荷采用稳定温差传热法。根据冷热负荷以及室内外设计参数可以计算出各空调区域或房间的送风量。再由负荷和送风量可以选择冷热机组,经计算,冷源采用
2、水冷式双螺杆冷水机组,共两台。郑州市有城市热力管网可用,故系统热源采用城市热力管网。风管及水管的水力计算采用假定流速法。本论文设计范围为:空调风系统、空调水系统、冷热源设计。主要内容为:负荷计算、空调系统方案选择、房间风量的计算、风系统设计及气流组织计算、水系统设计及相应的水力计算、设备选型和布置、空调冷热源设计选型。在整个设计过程中,严格遵循空调规范的规定,对各个环节进行综合考虑,尽可能实现节能、高效、环保。关键词:风机盘管加独立新风系统;设备选型;节能Ⅰ河南理工大学本科毕业设计(论文)AbstractAbstrac
