1、河南理工大学本科毕业设计(论文)摘要摘要本设计为青岛市某办公大楼舒适性空调系统,设计内容包括冷负荷计算,方案的比较,空气处理方案的选择,空调末端设备选型,水管路和风管路系统的设计计算及附属设备的选型,并进行设计说明书的编制和施工图的绘制。设计坚持可持续发展理论,树立了节约能源和全寿命周期成本分析的科学理念,从节能和环保出发,综合考虑建筑结构、使用要求、环境条件,在系统的选择、设备的选配及系统的运行控制等方面采取一定的节能措施,使系统在各种工况下均能高效节能运行。根据节能设计标准要求,结合计算软件,采用谐波法对整个大楼的冷负荷进行逐时计算;分析负荷日变化和全年变化情况,通过多个方案的可行性论证和
2、经济性比较,结合实际的能源政策,选用了水冷式螺杆机组加市内热网的冷热源运行策略。空调系统采用风机盘管加独立新风的空气-水系统。在设计计算的基础上,还进一步分析比较了不同建筑维护结构、设计参数、空调方案等对能耗的影响,提出空调系统各环节存在的问题及节能潜力。关键词:舒适性空调,可持续发展,建筑节能,室内空气品质II河南理工大学本科毕业设计(论文)AbstractAbstractThisdesignisabouttheconcentratedairconditioningsystemofsomeTechnologybuilding,includingaseriesofdesigncontentss
