住宅楼集中供冷系统的优化运行工况

Optimal Running Conditions of Residential Central Cooling System

以住宅楼集中供冷系统主要设备的能耗模型为基础,分析了系统各运行参数对设备能耗的影响,提出了系统能效比(SCOP)概念,建立了以SCOP为优化目标的供冷系统优化节能运行工况模型.以长沙市某住宅小区的集中供冷系统为研究对象,根据实测数据对优化模型进行求解,得到了该系统各运行参数的实时优化值.通过与实际运行工况下系统能耗的比较表明,文中建立的优化节能运行工况模型应用于住宅楼集中供冷系统,将会有很好的节能效果.

Based on the energy consumption model, the effect of running parameters on the energy consumption of the residential central cooling system was analyzed, a new term called system coefficient of performance （SCOP） was put forward, and an optimal model was established to get the maximum SCOP during the running of the system. Then, a cooling system in Changsha city was studied as an example. Its real-time optimal running conditions were obtained based on the testing data and the optimal model. Compared with the energy consumption of the system under the actual running conditions, the optimal model shows a remarkable effect of energy conservation when applied in the operation of the residential central cooling system.
