摘　　要：以重庆市某采用半集中式空调系统的酒店客房为研究对象,经实测发现其存在因新风未达到设计值及末端盘管出力不够而产生的室内热舒适性较差的问题,通过改变新风量并降低新风机组出口焓值以及调整室内送风状态点,并利用CFD(Computational Fluid Dynamics)对室内温度场、速度场及PMV指标进行了数值模拟,得到了室内热舒适性较好的运行工况,为酒店空调系统运行调适提供参考.In order provide reference for improvement of hotel air conditioning system operation adjustment.An on-the-spot test was made of a hotel room with semi-centralized air conditioning system in Chongqing.The results showed that it had poor indoor thermal comfort caused by the failure of fresh air and fan coil to reach the design value.Through changing the fresh air volume and reducing the enthalpy of the fresh air outlet to change the indoor air supply state point,and using the CFD to carry out a numerical simulation of the indoor temperature field,the speed field and the PMV index,a good operating condition of the indoor thermal comfort was achieved.
