1、築龍網zhulongxom建筑资料下載就在筑龙网长沙市某科研大厦空调工程设计摘要本设计为长沙市某科研大厦舒适性空调系统,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
2、荷进行逐吋计算;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燃气热水锅炉的冷热源运行策略。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,室内空气品质築龍網zhulongxomHVACdesignofTechnologybuildingofChangshaAbstractThisdesignisabouttheconcertra
