集中供暖条件下地板辐射供暖住宅建筑热环境仿真分析
Simulation and analysis of thermal environment in residential buildings with radiant floor heating under centralized heating system
摘要
Abstract
Effective monitoring of indoor temperature variations in individual households is essential for the refined control of district heating systems in residential buildings.In this study,a six-story residential building in Jinan was selected as the research object,and a thermal environment model with radiant floor heating was established.Indoor temperatures and energy consumption under different neighboring households'heating-stop conditions,supply-water temperatures,and supply-water flow rates were simulated.The effects of floor level,unit location,and neighboring-household heating conditions on indoor temperature and energy consumption are discussed,as well as the response characteristics under variable-flow and variable-temperature conditions.The results showed that,under all-household heating conditions,the indoor temperature of top-floor corner units was 2.36℃lower and energy consumption was 2.89 MJ/h higher than that of middle units,while bottom-floor corner units was 1.59℃lower and energy consumption was 5.79 MJ/h higher.Indoor temperature was most strongly influenced by the heating state of the upper neighboring units;when upper dwellings stopped heating,the indoor temperature of middle units decreased by 2.73℃and their average energy consumption increased by 2.99 MJ/h.At a constant supply-water temperature,increasing the flow rate significantly raised indoor temperature,yet the increase tended to saturate,whereas at a constant flow rate,indoor temperature and energy consumption increased approximately linearly with supply-water temperature.关键词
