            摘要:

            为了量化冷水系统各主要设备之间的选型设计及匹配情况,基于流分析,定义了各个设备的理想运行状态和冷水系统理想运行状态,并在此基础上提出了评价单个设备设计对系统影响情况的设备设计匹配度和评价系统整体设计匹配情况的系统设计匹配度。对某办公楼空调冷水系统中冷水机组和冷水泵的不同选型设计方案应用该评估方法计算了相关指标,比较了各方案中冷水机组和冷水泵的匹配情况,选出了匹配水平最高的设计方案。

            Abstract:

            To quantify the selection design and matching level of the main equipment of chilled water system, presents the ideal operation levels for the equipment and the system based on exergy flow analysis. According to the two ideal operation levels, proposes the matching degree for the equipment design to evaluate the influence of single equipment design on chilled water system and the matching degree for the system design to evaluate the matching level of the overall chilled water system. With the two indexes, evaluates the different selection design schemes of chillers and chilled water pumps of a chilled water system for an office building. Compares the matching degree of chillers and chilled water pumps in the different design schemes, and selects the best design scheme.
