摘要
为研究区域供热网络,多用户住宅建筑中出现的停热用户所导致的户间传热影响,研究基于TRNSYS数值模拟的方法构建并标定了一个综合考虑热力与水力耦合的多户型住宅供暖系统模型.并详细分析了不同调节条件下,八个不同建筑区域内的三种用户位置的相邻停热用户的影响.研究表明当停热用户位于正常供热用户的上方时,正常供热用户的单位面积热负荷将增加6.45 W/m2.停热用户的不同相对位置对其邻近的正常供热用户造成的影响各不相同,位于上方的停热用户对下层供暖用户的影响最为显著.
Abstract
To investigate the impact of inter-household heat transfer caused by non-heating users in district heating networks and multi-user residential buildings,this study constructs and calibrates a multi-family residential heating system model based on the TRNSYS numerical simulation method,comprehensively considering the coupling of ther-mal and hydraulic systems.The influence of adjacent shut-down users in three distinct user locations across eight different building areas under various regulation conditions is analyzed in detail.The research indicates that when a shutdown user is located above a normal heating user,the heat load per unit area of the normal heating user increas-es by 6.45 W/m2.The influence of shutdown users on adjacent normal heating users varies with their relative posi-tions,especially with the most significant effectiveness when the shutdown users are located below the normal heat-ing users.
