摘　　要：针对传统太阳能被动供暖技术普遍存在的得热量少或房间温度波动大的问题,提出了阶跃传热南向外窗与太阳能热风蓄热系统组合的被动式供暖技术,以充分利用建筑南立面获得更多的太阳辐射得热,同时提高围护结构的蓄热量,减少房间温度的昼夜波动。对太阳能热风蓄热系统提出了与光伏发电系统耦合的自力式控制方式,实现了热风蓄热系统的全被动运行。通过对某项目的数值模拟分析,研究了应用该组合技术的围护结构蓄放热特性及室内热环境状况。In view of the common problems of less heat gain or large fluctuation of room temperature in traditional solar passive heating technology,a passive heating technology is proposed,which combines the solar hot air heat storage system with the step heat transfer southward outer window.The aim of this combined method is to make full use of the south facade of buildings to obtain more solar energy,at the same time to improve the heat storage of the envelopes and reduce the diurnal fluctuation of indoor temperature.The self-dependent control method coupled with the photovoltaic power generation system is proposed to ensure the full passive operation of the solar hot air heat storage system.Through the numerical simulation analysis of a project,the heat storage and release characteristics of the envelope and the indoor thermal environment condition using the combined method are studied.
