摘　　要：为了对竖壁贴附射流与地板辐射复合空调系统的结露情况及舒适性进行数值研究,建立室内复合空调模型,以实测数据作为边界条件,利用Airpak3.0软件对该系统的热环境进行数值模拟,分析设计相对湿度、送风速度及排风口位置对室内热环境的影响,定性地分析室内各工况下相对湿度和舒适度指标的特点,发现当室内设计相对湿度适当降低或者送风温度高于地板表面温度时,都会提高人员舒适性并且降低了地板结露的风险,从而为竖壁贴附射流与地板辐射复合系统合理的运行设计提供了参考依据。To investigate the condensation and comfort of the downward directed vertical wall jets and floor radiation composite air conditioning system,the thermal environment of the system was simulated by Airpak 3.0.The indoor composite air conditioning model was established,in which measured data were taken as the boundary conditions.The effects of relative humidity,air supply speed,and position of air outlet on the indoor thermal environment under the design conditions were analyzed.According to the qualitative analysis of the relative humidity and comfort index under various indoor operating conditions,the following conclusions can be drawn.When the relative humidity during initial design is appropriately reduced or the temperature of air supply is higher than that of floor surface,the human thermal comfort will be improved.Meanwhile,the risk of condensation on the floor can be reduced.It provides a reference for the reasonable design and operating of the downward directed vertical wall jets and floor radiation composite air conditioning system.
