项目总结
汉森为评估提供了专业的工程服务, 中佛罗里达大学计算机科学大楼(54号楼)控制改造项目的设计和施工阶段.
对于评估阶段, 汉森通过回顾历史公用事业数据进行了ASHRAE二级能源审计, 进行设施现场调查, 执行空间功能分析, 确定设施改善措施, 审查当前的操作和维护程序，并策略性地对供暖系统的功能和能力进行调试, 透过楼宇自动化系统(BAS)的通风及空调系统. 还评估了BAS基础设施的升级和替换选项.
The design phase encompassed replacing three of the facility’s air-handling units (AHUs) and all of the existing fan-powered variable air volume (VAV) terminal boxes and associated electric duct heaters with new non-fan VAV terminal boxes with electric heat; replacing the BAS gateway, communication wire and field controllers; replacing field devices, sensors and actuators; replacing outside air dampers serving the new AHUs; and adding the stand-alone fan coil units to the BAS.
新的操作序列的优化策略包括备用冷却器分段和送风温度和静压复位. 该范围还包括通过增加旁通管道和所需阀门，将建筑冷冻水泵布局升级到当前的UCF标准.
This project was critical for hardening UCF’s main data center HVAC systems; the new fan array AHUs great improve system resiliency.
