摘　　要：地板供冷配合置换通风是改善地板供冷能力偏低,预防结露的有效措施之一。本文采用房间下部送风的方式,使之形成地面“空气湖”,阻隔潮湿空气与室内地板表面的直接接触。实验测试了有无置换通风条件地板供冷时房间地板表面、各墙壁面、顶棚及室内不同高度位置的温度分布,比较得出了配合置换通风对地板供冷的影响效果。The floor radiant cooling with displacement ventilation system is the one of the effective method to enforce the system cooling ability and prevent dewing. A displacement ventilation system was provided, it can form the ＂air layer＂ at the bottom of room so that resistance dewiness air meet directly the cold floor surface. The temperature distributing was tested such as floor surface, wall surfaces ,ceiling and indoor different place under the condition of the floor cooling lonely and with displacement ventilation, the conclusion shows the influence action floor cooling with displacement ventilation system.
