1、1/9 深交所技术中心机房空调冷冻水保障泛华建设集团有限公司深圳设计分公司陈京凤摘要：本文详细介绍了深圳证券交易广场的空调水系统设计。针对深圳证券交易广场各部门的多样化的用冷特点，尤其是技术中心机房的全年不间断的用冷特点，设计了合理的冷源设备配备；设备选型原则、备用原则明确、合理，满足了多样化、不间断的要求。关键词：超高综合楼、冰蓄冷、蓄冰量、设备选型、备用原则1 工程简况1.1 工程的自然简况本工程位于深圳市福田区中心区,是深圳证券交易所兴建的综合性办公大楼，全称为深圳证券交易广场。总建筑面积 263528m2,总建筑高度：237.1m，地上共46 层，地下共3 层。其中16 层为建筑塔楼下

2、部，79 层为抬升裙楼，1046 层为塔楼上部。本工程消防建筑分类为一类超高综合楼。建筑外形独特，如左图悬挑部分为79 层）：建筑用途：地下13 层为汽车库、设备用房；地下3 层局部为战时人防二等人员掩蔽所。地上1 层为深交所自用入口大堂及配套商业服务设施；2 层为出租办 公 区 大 堂；3 层 为 物 业 管 理 办 公 室；46 层 为 深 交 所 技 术 中 心 机 房；79 层为深交所营运、办公区，其中8 层设国际会议大厅、上市大厅、讲堂、教室、中国证券典藏专区、证券市场博览区、礼品展示区等等；10 层为员工食堂；1143 层为办公，其中16、32 为避难层兼设备转换层，33 层设厨房

3、；4446 为高级会所，其中44 层设厨房。标准层层高4.35m，避难层层高8.7m。1.2 工程的空调设计简况设计范围为空调、采暖、通风、防排烟设计、人防通风设计。设集中空调的范围：地下各层电梯等候厅和地上除避难层以外的全部楼层。其中47 层深交所技术中心机房的恒温恒湿空调由甲方另行委托专业公司 IBM 设计，由冷冻机房提供冷冻水。设冬季空调供热的范围：11-14 层高管办公区、89层档案和典藏、4446 层会所。本工程空调总面积约为 145650m2。根据空调冷负荷特点，空调冷源分A、B两个独立系统。A系统为全年供冷，总冷负荷2752RT，总装机容量2700RT；B系统仅夏季供冷，为蓄冰系

4、统，总冷负荷4415RT，总装机容量3350RT，蓄冰设备总蓄冰量18120RTh。2/9 根据空调热负荷特点，空调热源设两个风冷涡旋式热泵机组系统，提供热水，与供冷系统共用末端。空调末端采用多种组合形式：有全空气定风量系统、变风量系统、变风量风柜+单风道节流型VAV系统、变风量风柜+风机动力型VAV系统、新风+风机盘管系统、新风+水冷式恒温恒湿机系统等等。2 设计参数本工程是超高的大型综合建筑，针对建筑的功能多样化，空调要求多样化，空调设计计算参数选取是否准确合理，对整个空调系统的后续设计产生重大影响。2.1 空调室内设计参数高管办公区、楼顶会所夏季供冷，冬季供暖，房间温度夏季25C，冬季

33、蓄冰工况、主机和冰盘管联合供冷工况、主机单独供冷工况、冰盘管单独供冷工况；其中蓄冰工况为夜间电价谷段时储冰，主机和冰盘管联合供冷工况、主机单独供冷工况、冰盘管单独供冷工况为末端供冷。但本设计主机单独供冷工况无法保证末端设备所需的全部负荷和温度，因此只能作为极端情况下的一种备用补救措施；冰盘管单独供冷工况主要用于过渡季节；空调季节应以主机和冰盘管联合供冷工况为主。其原理如图：文档编码:CK2W2E7R3V4 HH7G3M4P1X7 ZS10R1W5H2S3文档编码:CK2W2E7R3V4 HH7G3M4P1X7 ZS10R1W5H2S3文档编码:CK2W2E7R3V4 HH7G3M4P1X7 Z
