XX某医院门诊楼空调系统设计 摘 要 本设计为XX某医院门诊楼空调系统设计，拟为之设计合理的中央空调系统，为室内人员提供舒适的工作环境。 系统主要采用风机盘管承担空调房间的冷负荷与热负荷，每个房间的吊顶内安置一到二个风机盘管。新风则通过独立的新风管道先送入风机盘管，再与回风混合一起送入房间。新风机组吊顶安装，每一层楼安装一台新风机组负担该层所有空调房间的新风负荷。该空调系统的优点是占用建筑面积少，可集中供冷和供热；同时各末端装置有独立的开关和调节功能，各房间的温度可独自调节与控制，并且防止了空气的交叉感染。对于候诊大厅等少数房间采用了全空气一次回风系统。空调水系统采用闭式系统,因为它除了不易污染,节省初投资外,还具有很大的节能效果。 本设计内容包括：空调冷热负荷计算；空调系统的确定及论证；送风状态参数及送风量的确定；空气处理设备的选型；冷热源的选择及设备选型；气流组织计算；水力计算；其他设备的选择；保温与防腐以及减振和消声等内容。 关键字：空调系统，全空气系统，风机盘管加新风系统，性能比较 THE AIR-CONDITIONING ENGINEERING DESIGN OF THE TUMOR HOSPITAL OUT-PATIENT FLOOR IN TIANJIN ABSTRACT This air-conditioning systems design for the Tianjin Tumor Hospital out-patient floor design it to be a reasonable central air-conditioning system for indoor staff provide a comfortable working environment. Fan-coil system is mainly used air-conditioned rooms bear the cooling load and the heat load, the ceiling of each room placement within 1-2 fan-coils. The new wind of fresh air through independent channels into the first fan-coil, and then mixed together with return air into the room. New wind generating units installed on ceiling, each floor to install a new air unit of the burden of all air-conditioned rooms in the new wind load. The air-conditioning system has the advantage of occupying less floor space, cooling and heating can be concentrated at the same time, the terminal device and a separate regulatory function switch, the room temperature alone can regulate and control, and prevent cross-infection of the air. The waiting hall and a few rooms used a return air to the entire air system. Air-conditioning system uses closed-water systems, not because it apart from pollution, save initial investment, but also has great energy-saving effect. The design elements include: hot and cold air-conditioning load calculation; air-conditioning system and the determination of proof; air supply and air supply parameters of the determination; selection of air-handling equipment; cold and heat source of choice and sele
