养老建筑功能升级改造的给排水设计

Water Supply and Drainage Design of an Elderly Care Building during Functional Upgrading and Renovation

根据新项目团队的机电标准和运行经验要求,需对已建设过半的某养老建筑的给排水系统进行升级改造。基于经济分析及比选,确定采用变频供水及紫外消毒的给水系统,室内污废合流、室外雨污分流的排水系统,多级计量系统,海绵城市以及绿建2星节能系统,并对热水系统进行节能优化和运营成本分析,最终实现了依法合规的给排水系统改造,可为类似项目提供参考。

This paper introduced the upgrading and renovation of the water supply and drainage system of an elderly care building which has already been constructed for more than half of the construction in the southern region based on the mechanical and electrical standards and operational experience requirements of the new project team.Based on economic analysis and comparison,the water supply system was transformed into the system with variable frequency water supply and ultraviolet disinfection,the drainage system was transformed into indoor sewage and wastewater combined drainage system and outdoor rainwater and sewage separate drainage system,the multi‑level metrology system,sponge city and green building 2 star energy‑saving system were proposed,the energy saving of the hot water system was optimized,and its operating cost was analyzed.The results aim to provide reference for similar projects.
