STUDY ON THE IMPACT OF UNHEATED USERS ON MULTI-USER CENTRALIZED HEATING BUILDING
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.
