夏热冬暖地区开窗通风与壁体遮阳对集装箱房室内热环境的影响

Influence of Window Open Ventilation and Wall Shading on Indoor Thermal Environment of Container Room in Hot Summer and Warm Winter Areas

为了考察我国夏热冬暖地区集装箱建筑室内热环境状况,提出相应的改善措施,通过搭建足尺集装箱房,在厦门夏季典型气候条件下,对比测试集装箱房开窗通风及东西向壁体薄板遮阳对其室内热环境的影响.结果表明:集装箱房采用开窗通风,可显著降低室内温度;采用外墙遮阳,可稍缓解夏季集装箱房室内高温,但效果并不理想;两种降温方式均能在一定程度上降低室内预测平均投票数(PMV)值,但不能使室内达到热舒适范围,夏季开启空调仍然非常必要.

In order to investigate the indoor thermal environment of container room in hot summer and warm winter areas,and to find the improvement measures,a full size container room was constructed,under the typical summer climate of Xiamen,the indoor thermal environment of container room with ventilation and eastwest wall shading was tested.The results show that the temperature of container room can be significantly reduced by natural ventilation;the heat of the container room in summer can be slightly relieved with the external wall shading,but the effects are quite limited.Both cooling methods can reduce the indoor predicted mean vote（PMV）value to a certain extent,but the indoor thermal condition is uncomfortable,and air-conditioning is still necessary in summer.
