摘　　要：对太阳能建筑室温及负荷特征分析发现:采暖期室内热环境状况难以完全满足热舒适要求,需与主动式采暖系统配合使用;而且太阳能建筑采暖期部分昼间时间室温高于采暖设定温度.因此,与之配合的主动系统存在间歇模式运行来满足室内温度要求的条件.分析提出了间歇采暖地板结构设计和运行参数的选用原则;对间歇采暖与被动太阳能技术耦合调节的室温变化特征分析结果表明:耦合调节室温平均值可维持在18℃左右,且波动幅度在2～3℃;在减小供暖时间的同时也避免了由于连续采暖造成的室内过热现象,对节约采暖能源及保证室内热舒适条件均起到积极作用.On the basis of the indoor temperature and heat load characteristics of passive solar heating house, it is found that., the thermal environment can not fully satisfy the thermal comfort requirements during ＂the heating period, and it needs to combine with the active heating system. However, the passive solar house indoor temperature is higher than setting temperature in the part time of heating period. Therefore, the active system should apply intermittent running mode to meet the requirements of the indoor temperature conditions. The selection principle of the intermittent heating floor structure design and operation parameters were obtained and the room temperature change characteristics under the adjustment of the coupled intermittent heating and passive solar energy technology analyzed. The results show that the average room temperature can keep 18℃or so, and the fluctuations remained between 2-3℃ The coupled regulation technology reduces the heating time and avoids the indoor overheating caused by continuous heating at the same time, and plays a positive role in heating energy saving and indoor thermal comfort.
