摘　　要：针对被动式太阳房普遍存在的夏季室内温度过高的问题,提出4种不同的降温措施。以新疆石河子市农村地区的一栋既有被动式太阳房为研究对象,采用数值模拟结合试验测试的研究方法,对比分析这4种措施的降温效果。结果表明:被动式太阳房在自然状态或采用各降温措施时,其室内温度的模拟值与实测值之间的偏差的平均值为2℃,但温度变化趋势一致,具有较好的吻合性,证实了数值模拟的可行性;根据实测结果,被动式太阳房在采用遮阳、关闭南窗结合遮阳及热压通风的降温措施时,分别有46%、50%和50%的时间可以达到热舒适性要求;将热压通风与遮阳结合使用,有92%的时间可以达到热舒适性要求。Four different cooling measures were proposed to aim at the excessive indoor temperature problem of passive solar house in summer.A passive solar house in the Shihezi area of Xinjiang was taken as the study object.The method of numerical simulation combined with an experimental test was used to compare and analyze the cooling effect of the four cooling measures.The results show that:comparing the numerical simulation results with the experimental results,the average value of the indoor temperature deviation under each cooling measure is 2℃,but the temperature change trend is consistent and has good conformity,which confirms the feasibility of the numerical simulation.Compared with the passive solar house in the natural state,thermal comfort requirements can be met 46%,50%and 50%of the time,respectively.Using shading,closing the south window combined with shading or thermal pressure ventilation,thermal pressure ventilation combined with shading achieves thermal comfort requirements 92%of the time.
