摘　　要：概述了目前住宅热水系统中实现“零冷水”目标的多种改造方式。通过对比分析,总结了各种改造形式的适用场景及其优缺点,尤其聚焦于一种工程量较小、改造灵活且节能效果显著的零冷水热水系统。旨在为居民提供在选择热水系统改造方案时的参考,以优化热水使用体验,减少水资源浪费,并避免非专业改造可能带来的问题。This paper outlines various retrofitting methods to achieve the“zero cold water”objective in current residential hot water systems.Through comparative analysis,it summarizes the applicable scenarios,advantages,and disadvantages of each retrofitting approach,with a particular focus on a type of zero cold water hot water system that requires minimal construction effort,offers flexible retrofitting options,and demonstrates significant energy-saving effects.The purpose of this paper is to provide residents with a reference when selecting retrofitting schemes for their hot water systems,in order to optimize hot water usage experience,reduce water waste,and avoid potential issues associated with non-professional retrofitting.
