专业名称:建筑环境与设备工程作者姓名:赵兴元指导教师:张登春
摘要:本设计为舒适性空调系统设计。该医院大楼共有13层空调层,不包括地下层(机房),主要为病房、值班室、医生办、护士站等。考虑到其为中层建筑,采用一套空调系统即可。本设计根据该建筑的具体工况,进行了详细的负荷计算,选用了台佳螺杆式冷水机组和申特电热锅炉集中供冷、供热;由该建筑本身的结构特点采用了全空气集中系统和半集中式系统(风机盘管+新风);为确保每个房间达到理想的温湿度要求,进行了完善的风、水系统设计以及详细的气流组织、水力计算;为了给病人、医务人员提供一个安全、舒适的住院、工作环境,空调设备、管道等实施了消声、减震和保温措施,并且在地下冷水机房、楼梯间、电梯间前室采取了防排烟设计(加压送风系统)。本设计介绍了中央空调系统设计的一般过程,详细地对其设计思路进行理论论证和阐述,并对该空调工程进行了优化设计,提出了将通风系统与排烟系统合用的构想。

Abstract: This design is fortable air condition system. This building has 13 layers of air condition totally with mainly ward, on-duty room, doctor office, nurse station etc,. not including the underground layer(engine room). In consideration of armed police hospital for intermediate construction, it is enough to adopt a set of air condition system. According to the concrete work condition of the building, we carry on a detailed burden calculation to the air conditioner load and choose to use Tecka screw water chilling unit and Shente electrode boiler to provide cold and heat water concretely; we also adopt the whole air concentration system and the half concentration type system (breeze machine dish tube and breeze) according to the structure characteristics of the building; in order to make sure that every room can up to the humiture requirement, this design makes a perfect design to the wind and water system and a particular calculation to the air anization and waterpower; it also takes the measures such as noise elimination, shock attenuation and heat insulating material for the air conditioning units and pipes and the design of defending row smoke in the underground cold water engine, stairs, elevator room is also adopted. This design introduces the general process, expounds the design reason particularly from its theory, it also makes the optimal design to this air conditioner project and put forward a plan to share ventilation system and smoke extraction system.
