郑州金帝集团办公楼空调系统设计

摘要

本设计为郑州市金帝集团办公楼舒适性空调系统，设计内容包括冷负荷计算，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，采用冷负荷系数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经济性比较，结合实际的能源政策，选用了水冷式螺杆机组的冷源运行策略。

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。
