摘　　要：基于福建省某宾馆空调系统末端改造项目,针对采暖问题房间展开室内气流组织研究。经过现场检测,项目中问题房间的风机盘管进出风口都为顶部侧送顶部侧回,使空调系统送回风短路,造成室内温度过低。为改善此问题,选取现状方案和两个优化方案针对典型问题房间进行室内气流组织模拟,优化方案1送回风方式采用顶部下送顶部下回,优化方案2为顶部下送顶部下回。模拟结果显示,优化方案1和优化方案2室内各梯度温度均能达到设计温度要求20℃,在人员活动区0.9 m处最低温度23.55℃。并且方案2室内温度略高于方案1室内温度0.2~0.3℃。根据优化方案对问题房间的空调系统末端进行改造,改造后室内温度和噪声均可达到设计要求。Based on the terminal renovation project of air-conditioning system in a hotel in Fujian Province,the paper studies the indoor airflow organization in the room with heating problems..After on-site inspection,the fan coil inlet and outlet of the problem room in the project are all sent to the top side by the top side,so that the air conditioning system is sent back to the air short circuit,resulting in the indoor temperature is too low.In order to improve this problem,the present situation scheme and two optimization schemes are selected to simulate the indoor airflow organization for the typical problem room.The optimization scheme 1 sends the return air way by the top down send the top down return,and the optimization scheme 2 is the top down send the top down return.The simulation results show that the indoor gradient temperature of optimization scheme 1 and optimization scheme 2 can meet the design temperature requirement of 20℃,the lowest temperature is 23.55℃ at 0.9 m in the personnel activity area,and the indoor temperature of scheme 2 is slightly higher than that of scheme 1 by 0.2~0.3℃..According to the optimization scheme,the end of the air conditioning system in the problem room is modified,and the indoor temperature and noise can meet the design requirements after the modification.
