空间划分对太阳能建筑室内温度差异化影响

STUDY OF THE NON-UNIFORM EFFECT OF SPACE DIVISION ON PASSIVE SOLAR HOUSE INDOOR TEMPERATURE

结合拉萨、银川及西安地区的冬季气候条件,建立典型建筑模型,利用热平衡方程组分析空间划分模式及隔墙热阻等对室内不同空间温度的差异化影响。结果表明,室内空间合理划分可明显提高主要房间的室内温度,但受太阳辐照强度和室外空气温度差异的影响,不同地区提高的幅度有所不同。依据典型建筑模型分析,拉萨地区民居采暖期主要房间空气温度可提高13.6%,达到16.7℃;银川地区可提高22.7%,达到9.2℃;西安地区可提高10.3%,达到11.8℃。

The amount of heat collected in passive solar building is relatively less, which can cause the problem of low indoor temperature in winter. Through the establishment of typical building models, the influence of different interior space division and thermal resistance of partition wall on the temperature difference of different interior space division have been analyzed by building heat balance equations according to the outdoor thermal environment parameters of Lhasa, Xi＇ an and Yinchuan area respectively. The results showed that the indoor temperatures of the main room can be raised effectively through the appropriate division of interior space, but the improved degree of indoor temperature is different in different area because of the influence of the difference in solar radiation intensity and the outdoor air temperature. According to the analysis of typical building model, the main room indoor air temperature of dwelling in Lhasa area during heating period can be increased by 13.6%, reaching 16.7℃; In Yinchuan area, it can be increased by 22.7%, reaching to 9.2℃; In Xi＇an area, it can be increased by 10.3%, reaching to 11.8 ℃.
