摘要
医院内的空气环境对于一个院的医疗环境来说可谓是一个非常重要的一部分。本次设计主要是给医院做的新风空调，给医院的治疗室和病房提供一个舒适，洁净，卫生的空气环境。该空调系统主要采用风机盘管加新风的方式来为房间输送新风和制冷。新风机组、新风管道和风机盘管都是采用吊顶安装的方式，新风机组从室外获得新风混合由风机盘管制冷的室内回风，通过百叶风口一起输送到室内，为室内提供一个即舒适又健康的空气环境。
我的设计主要分为以下几个部分，首先是空调的冷负荷的计算，然后是新风量的计算，其次是根据新风量对设备的选型，之后就是对于风道的设计，根据空调设计手册，设置风道的形式，最后是水系统，先设计水系统的布局，然后进行水力计算。

The design of air conditioning system for the hospital in
Guangzhou
Abstract
Air in the hospital environment for a hospital medical environment is a very important part of it. This design is mainly to a hospital doing outdoor air, to the treatment room and ward of the hospital providing a comfortable, clean, the air environmental health. The air conditioning system is mainly adopt fan-coil unit plus fresh air way of conveying fresh air and cooling for the room. Fresh air fan coil units, air piping and adopt the way of condole top installation, fresh air units from the outdoor fresh air mixed by cold room return air fan-coil unit, through the shutter tuyere to indoor, together to provide a comfortable and healthy indoor air environment.
My design mainly divided into the following several parts, the first is the air conditioning cooling load calculation, and then the calculation of the fresh air volume, and the second is according to the new air volume of equipment selection, then to the design of the air duct, according to the air conditioning design manual, set in the form of air duct, and at last the water system, to design the layout of the water system, and hydraulic calculation
Keywords air-conditioning system; Fan coil plus fresh air system
