摘 要： 为解决建筑集热量与居民热舒适需求难以匹配的问题，以太阳能资源高适宜区银川和一般适宜
区兰州的附加阳光间式太阳能建筑为研究对象，利用 Design Builder建筑能耗分析软件，通过数值模拟的方
法研究不同采暖模式、辅助热源强度组合下主要房间的室内温度状况及建筑的能耗情况。结果表明：在太阳
能供暖的基础上，辅以辅助热源能够有效解决建筑集热量与居民热需求不符的矛盾，并且降低采暖能耗。对
于银川和兰州地区，在分别采用分时分区采暖模式且辅助热源强度下限为 60 W/m
2和80 W/m 2时，满足居民
热舒适需求同时最大程度地减少能源消耗；相对于连续采暖，分时分区采暖虽然在短时期内增加建筑平均热
负荷，但是在一定程度上降低整个采暖期累计热负荷，减少建筑使用阶段 50 %~60 %碳排放量，可见该方法
对降低乡村建筑能耗起到较大作用。 关键词：建筑节能；数值模拟；被动式住宅；辅助热源

Abstract: In order to solve the problem that it is difficult to match the heat collection of
buildings with the thermal comfort needs of residents, an additional solar room solar building in
Yinchuan, a highly suitable area for solar energy resources, and Lanzhou, a general suitable area for
solar energy resources, was taken as the research object. Using the Design builder building energy
consumption analysis software, the indoor temperature and building energy consumption of the main
rooms under different heating modes and auxiliary heat source intensity combinations were studied by
numerical simulation. The results show that: On the basis of solar heating, auxiliary heat source can
effectively solve the contradiction between building heat collection and residents’ heat demand, and
reduce heating energy consumption. For Yinchuan area and Lanzhou area, when adopt the time-sharing
district heating mode respectively and the lower limit of auxiliary heat source intensity is 60 W
/m
2and
80 W
/m 2, can reduce the energy consumption while meeting the thermal comfort needs of residents.
Time-sharing district heating versus continuous heating, although the former increases the average thermal
load of the building in a short period of time, it reduces the cumulative heat load of the whole
heating period to a certain extent, and reduces the carbon emission of 50%~60% in building use stage.
It means that this method has played a greater role in reducing energy consumption of rural buildings. keywords: building energy saving; numerical simulation; passive building; auxiliary heating source
