摘要：在“双碳”目标下，随着人们绿色节能意识的不断提高，中央空调系统作为建筑中重要的能源消耗设
施，越来越受到社会关注。空调水系统作为中央空调系统的关键组成部分，其能耗状态、运行策略以及节能设计
都离不开对系统水力特性的考量。从这一角度出发，分析了中央空调水系统存在的大流量、小温差、高阻力和水
力平衡等问题，探讨了如何通过分析水力问题看供需失衡的本质，并且通过讨论系统环路水力特性与系统阻力特
性模型，推导出相应水力公式与分析结论。给出中央空调水系统的设计既要系统低阻性，又要水力平衡性好，还
要水力可调性高，且系统配置合理的综合节能设计的参考结论，从而助力中央空调节能改造与设计应用于“双
碳”绿色节能领域。

Abstract: Under the "dual carbon" goals, with the continuous improvement of people's green and energy-saving awareness,
central air conditioning systems, as important energy consumption in buildings, are receiving more and more social
attention. The air conditioning water system is a key component of the central air conditioning system, of which the energy
consumption status, operation strategy and energy -saving design cannot be separated from the consideration of the
hydraulic characteristics of the system. From this perspective, the problems of large flow rate, small temperature difference,
high resistance and hydraulic balance in the central air conditioning water system were analyzed. It was explored that how
to understand the essence of supply-demand imbalance through analyzing hydraulic problems, and corresponding hydraulic
formulas and analysis conclusions were derived by discussing the hydraulic characteristics of the system loop and the
model of system resistance characteristics. A reference conclusion was provided for the comprehensive energy-saving
design of the central air conditioning water system, which requires low system resistance, good hydraulic balance, high
hydraulic adjustability and reasonable system configuration, in order to assist the energy-saving transformation and design
of the central air conditioning in the field of "dual carbon" green energy conservation.
