摘要
根据重庆地区的气候特征和太阳能资源分布特点,提出了适于重庆地区的太阳能建筑一体化应用技术思路——太阳能辅助室内通风降温措施,即充分利用重庆地区夏季强烈的太阳辐射,强化'烟囱效应',促进建筑内部自然通风,从而改善夏季室内酷暑闷热的热湿环境,达到节能目的,实现太阳能的被动式利用。通过实测分析,在太阳能的热作用下,室内产生了0.16～0.22m/s的风速,同比提高14%～40%,同时室内平均温度比室外的平均温度降低2.6～3.4℃,有效改善了室内热环境舒适状态。
According to the characteristics of the climate and distribution of solar resource in Chongqing, the technology idea of integrated application of solar energy and building is proposed, which is suitable for Chongqing area, i.e. solar assisted indoor ventilation cooling measure, which takes full advantage of the strong solar radiation in summer and strengthens the ＂chimney effect＂ to promote natural ventilation inside the building, improve the summer indoor hot and humidity environment, save energy and achieve solar energy passive using. Experiments and analysis show that the 0.16～0.22 m/s indoor air speeds are produced by the thermal effect of solar energy, which is increased by 14%～40%. And the average indoor tempera- ture is 2.6～3.4℃ lower than the outdoor average temperature, and the indoor thermal comfortable state is effectively improved.
