摘　　要：针对由集装箱改造而成的隔离病房的冬季热舒适性和病毒浓度的相关问题,采用数值模拟软件研究供暖条件受限情况下空调送风角度对房间整体的影响。结果表明:送风角度为0°(垂直向下)时,房间存在明显的热力分层现象,同时房间部分壁面局部过热,导致壁面热损失最大;适当增大空调器送风角度可改善室内热环境,提高房间对热量的利用率,但同时也会导致房间垂直方向上的病毒浓度升高,威胁室内人员的健康安全。Aming at the related issues of winter thermal comfort and virus concentration in the isolation ward transformed from the container,the influence of the air supply angle of the air conditioner on the overall room under the limited heating conditions was studied.The results show that when the air supply angle is 0°(vertical downwards),there is obvious thermal stratification in the room,at the same time,part of the wall surface of the room is locally overheated,which maximizes the wall heat loss.Appropriately increasing the air supply angle of the air conditioner can improve the indoor thermal environment and the heat utilization rate in the room,but it will also lead to the increase of virus concentration in the vertical direction of the room and threaten the health and safety of indoor personnel.
