摘　　要：通过实验和CFD模拟相结合,分析了不同工况下的置换通风—地板供冷复合空调系统的热舒适性,得到了不同的送风风速、不同的地板表面温度以及提高送风温度对室内的速度场和温度场的影响。对实验室进行建模,利用CFD的后处理软件对复合系统的速度场和温度场进行分析,对其热舒适性给予了评价。研究结果表明,在良好设计的前提下,置换通风—地板供冷复合式空调系统充分发挥了两者的优点,可弥补各自不足,具有节能、舒适和空气品质良好的特点。Based on the combination of the experiment and CFD, the thermal comfort of DisplacementVentilation Floor Cooling Compound Air Conditioning System is analyzed in different working status, obtainingthe influences of different air inlet velocity, various temperature of floor surface and air inlet temperaturerising on the temperature field and velocity field. By simulating the laboratory, the post treatment softwareof CFD is utilized to analyze the velocity field and temperature field of combination system with the evaluationon the thermal comfort. The results show that, with good design, the compound system combining with theadvantage of two air conditioning forms, displacement ventilation and floor cooling system, can show eachadvantage fully and make up for the disadvantages. This system is energy-saving, comfortable, and of goodair quality.
