浅层地热能联合太阳能集热墙系统夏季降温试验研究

STUDY OF COOLING EXPERIMENT WITH SYSTEM COMBINING SHALLOW GEOTHERMAL ENERGY WITH SOLAR COLLECTING WALL IN SUMMER

针对目前被动式太阳房普遍存在的夏季室内过热现象,提出一种浅层地热能联合太阳能集热墙系统。并在石河子地区对采用该系统的被动式太阳房进行试验测试,对比分析3种通风模式和3种通风时间的降温效果。试验结果表明:采用浅层地热能联合太阳能集热墙系统的通风模式C3的室内平均温湿度明显优于其他模式,平均温度降低了2.64℃;通风时间为12 h的C5模式,其被动降温效果优于其他两种模式,且随着通风时间的延长,被动降温效果出现下降的趋势。

Aiming at indoor overheating phenomenon of passive solar house in the summer, the system combining shallow geothermal energy with solar collecting wall was proposed. And the experiment and test of passive solar house with this kind of system were carried out in Shihezi region, the cooling effects of three ventilation modes and three ventilation times were contrastively analyzed. The experimental results show that the indoor average temperature and humidity using the system combining shallow geothermal energy and solar collecting wall with the C3 ventilation mode was obviously better than other modes, and the average temperature decreases 2.64℃; Furthermore, the passive cooling effect of the C5 mode with 12 h of ventilation time is better than other two modes, and with the extension of the ventilation time, the effect of passive cooling appears descend trend.
