摘　　要：随着经济的发展,对能源的需求日益增加,而间歇供暖能有效地减少能耗,因此对间歇供暖的研究显得格外重要.文中主要研究了间歇供暖在近零能耗建筑内的应用,通过数值仿真方法探索了地板辐射采暖房间在过量/欠量供暖条件下,供热量、保温形式和墙体数量对房间温度、供暖效率及房间能耗的影响.研究分析了各种工况下房间升降温曲线及供暖运行时长,以及各工况下房间供暖效率及能耗程度.结果表明:从3倍供热量到10倍供热量,外保温一面外墙房间的供暖时间比例减小了91.4%,平均能耗减小了64.5%;从3倍供热量到8倍供热量,内保温一面外墙房间与外保温一面外墙房间相比,房间供暖时间比例分别减小了10.9%、2.4%、1.7%、2.0%、1.5%;从3倍供热量到5倍供热量,内保温两面外墙房间的平均能耗要比外保温两面外墙房间分别增加了54.1%、50.3%、32.3%.With the development of economy,the demand for energy is increasing,and intermittent heating can efficiently reduce energy consumption.Therefore,the research on intermittent heating is particularly important.This paper focuses on the application of intermittent heating in near-zero energy building,the effects of heating capacity,insulation form and exterior wall quantity on the temperature change,heating efficiency and energy consumption are investigated in floor radiant heating room with over/under heating system.Numerical simulation is established the research and the temperature rise and fall curves and heating operation time under various working conditions are obtained,and the heating efficiency and energy consumption of the room under various working conditions are analyzed.The results show that when the heating capacity increased from 3 times to 10 times,the ratio of heating time decreases by 91.4%and the average energy consumption decreases by 64.5%in one-exterior wall room with external insulation.When the heating capacity increased from 3 times to 8 times,the ratio of heating time of one-exterior wall room with external insulation decreases by 10.9%,2.4%,1.7%,2.0%and 1.5%separately based on that of one-exterior wall room with inner insulation.When the heating capacity increased from 3 times to 5 times,the ratio of heating time of two-exterior wall room with external insulation decreases by 54.1%,50.3%and 32.3%separately based on that of two-exterior wall room with inner insulation.
