XX市人民医院门诊楼 空调工程设计 Air-conditioning Design for Nanning Municipal Peoples Hospital outpatient buiding 院系名称：XXXXX 班 级：建环XX 学 号：XXXX 学生姓名：XXXXX 指导教师：XXXXX XXX年 XX月 摘要 本设计为XX市人民医院门诊楼中央空调工程设计。在负荷计算的基础上，通过方案比较，采用了风机盘管加独立新风和全空气两种空调系统形式。风机盘管为卧式暗装，新风不承担室内负荷水管用泡沫橡塑保温风管离心玻璃棉Abstract The design of Nanning Peoples Hospital outpatient building air conditioning was designed. On the base of cooling load, heating and moisture load calculation, primary air fan-coil system and all air system are adopted by way of technical and economic analysis. The fresh air doesn’t undertake indoor load and delivers air through double deflection grille after mixing the return air in the horizontal recessed fan coil. The return air is harnessed one time by the air handling unit in the all air system and the handled air is delivered through double deflection grille by sidewall air supply. The fresh air is supplied by hole or shaft and handled by the fresh air handling unit. The chilled water which is a closed two-pipe direct return water system is supplied by the refrigerating plant room. The thermal insulation material of water pipe and air duct are foam plastics and centrifugal glass wool respectively. Measures of noise elimination, damp, fire prevention and smoke extraction is considered during the design. Key Words: air conditioning, primary air fan-coil system,all air system. 目录 摘要 I Abstrct II 1 工程概况 1 1.1 原始资料 1 1.2 计算参数 1 1.2.1基本气象参数 1 1.2.2室外计算参数 1 1.2.3室内设计参数 1 1.3 动力资料： 2 1.4土建资料 2 2 负荷计算 3 2.1 围护结构瞬变传热形成冷负荷的计算方法 3 2.1.1外墙和屋面瞬变传热引起的冷负荷 3 2.1.2内墙,楼板等室内传热维护结构形成的瞬时冷负荷 3 2.1.3外玻璃窗瞬变传热引起的冷负荷 4 2.1.4透过玻璃窗的日射得热引起的冷负荷 4 2.2 设备散热形成的冷负荷 4 2.3照明散热形成的冷负荷 5 2.4 人体散热形成的冷负荷 5 2.5 新风冷负荷 5 3 空调方案的确定 8 3.1 空调方案的分类 8 3.1.1按空气处理设备的集中程度分为 8 3.1.2按承担室内负荷所用的介质分为 8 3.2空调方案的比较 8 3.3空调系统形式确定 10 4 确定风量、送风状态点及选型计算 12 4.1 风机盘管加独立新风系统 12 4.1.1夏季室内新风量的确定 12 4.1.2新风处理状态的确定，总风量及风机盘管风量的确定 13 4.1.3风机盘管选型 16 4.1.4新风机组的选型 17 4.2 全空气系统 17 5 风管水力计算 20 6 水管水力计算 22 6.1水系统形式的分类 22 6.1.1按管道数目分 22 6.1
