中 央 空 调 签 证 单

根据此楼功能要求，以业主的长远利益为出发点，为达到技术可靠，经济合理，管理方便，功能调整的灵活性及使用安全可靠之目标。在比较各种方案的可行性及水系统形式后，此设计确定方案为：六层大写字间采用集中式空调系统，四五层客房采用风机盘管加独立新风系统两种方式；水系统采用一次泵、双管制带自控的系统。根据夏季空调计算负荷依次选择冷水机组、末端设备、新风机组、风口。在对各支路及层面进行水力计算后，依据管路特性曲线及泵的性能曲线选择泵的型号，力求冷冻水循环泵设计流量与实际一致，同时保证实际工作点能维持较高的效率。另外在设计过程中，其它详细计算有：膨胀水箱容积、分水器、集水器、调节阀的口径、保温层厚度、防火排烟及车库通风设计计算等。

This study presents a nonlinear optimization technique (NOT) for conducting the back analyses of geotechnical engineering problems based on the field observations. Additional auxiliary techniques are incorporated to enhance the convergence and stability of the NOT. The developed NOT and additional auxiliary techniques are incorporated into a finite element code and then applied to the back analysis of excavation-induced wall deflection. A number of hypothetical excavation cases with various scenarios of stratigraphy and two quality excavation case histories are used to validate the developed NOT, in which the dominant soil parameters are treated as target parameters. Results show that the wall deflections of all hypothetical and actual excavation cases at each stage can be accurately and efficiently backfigured.
