1、中央空调工程设计AirConditioningSystemDesignforTheFourthHospitalofShijiazhuang摘要本设计主要针对河北省石家庄市第四医院进行了空调水系统、空调风系统、防排烟系统、制冷机房和换热站的设计。本建筑共有14层,包括地上12层数与任务书等不符层和地下2层。地上1~4层为门诊部,5~11层为住院部,顶层为娱乐场所(包括乒乓球室、台球室和舞厅);地下一层主要是空调机房和换热站,地下二层主要是汽车库。本设计主要包括地上1~12层的空调、通风及冷热源设计。其中包括房间的冷、热负荷及送风量的计算;空调系统方式的确
2、定及风系统、水系统阻力计算;空调主机房的设计与计算和绘制施工图纸。经计算,在设计工况下系统夏季总冷负荷为1561kW,冬季总热负荷为1983kW。本设计采用新风加风机盘管系统,室外新风经过新风机组处理到室内焓值后,被送入风管末端的双层百叶,不承担室内冷热负荷,却在冬季承担室内湿负荷。夏季由螺杆式水冷冷水机组提供温度为7/12℃的冷水,冬季由汽水换热器提供65/40℃热水,制冷机房和换热站都位于地下一层。冷却水塔提供30/35℃的冷却水。对于地上防排烟部分,消防楼梯间采用自然排烟,合用前室采用加压送风,走廊采用机械排烟方式。汽水换热器与制冷机组共用一套循
