摘要：
介绍了该工程的基本情况。为降低运行费用、提高空调舒适度，工程采用冰蓄冷、大温差供水的低温变风量系统加独立的新风系统。采用冰蓄冷系统充分利用峰谷电价差，可节省系统的运行费用；采用低温变风量系统可以减少末端设备的送风量，减小管道尺寸，降低输送能耗，同时由于低温送风降低了室内空气相对湿度，使环境舒适度得以改善。
Abstract：
Presents the basic situation of the project. The ice thermal storage system, chilled water system with large temperature difference between supply and return chilled water and VAV system with low temperature air supply combined with dedicated fresh air system are used to reduce operating costs and improve occupants’ thermal comfort. The operating cost can be reduced by adopting the ice thermal storage system to utilize the power price difference between high and low power demand periods. The adoption of the VAV system with low temperature air supply can reduce the air quantity, duct size and air transportation power consumption. At the same time, the low temperature air supply system provides more comfortable indoor environment due to lower relative humidity.
