| 摘 要： | 通过建立机组模型，对变冷凝温度控制和冷凝器变速风扇对风冷式冷水机组性能系数（COP）的改善和节能潜力进行了研究。当这两种技术同时应用时，机组COP能提高达51.8%。利用所建立机组模型，对某典型公共建筑的节能潜力进行分析，机组年度能耗下降了7.7%，节能效果显著。

| Abstract: | With the developed chillers model, this paper investigates how condensing temperature control （CTC） and variable speed condenser fans （VSF） can be applied to improve the performance and reduce the electricity consumption of air-cooled chillers serving an office building. There is a 51.8%increase in the chillers COP when CTC and VSF are used together. The annual electricity savings of the chillers are estimated at 7.7% with CTC and VSF for a representative office building. This shows the possibility of reducing the future electricity demand for the local commercial sector by the enhanced condenser features. |
