1、-范文最新推荐-1 / 44五星大酒店空调通风系统设计+CAD图纸设计题目来源酒店是一个人员众多的公共场所，温度、湿度、清洁度和新鲜空气量等，对房客和酒店职工等影响很大。污浊含尘的空气容易传播某些疾病。因此，酒店的空气环境越来越被商业部门重视。已加设良好通风空气调系统的酒店，深受广大群众的欢迎。酒店建筑的空调设计不同于办公、百货商场等建筑，它拥有平面建筑空间大，人员密度大， 房间类型多等特点。因此，设计酒店暖通空调系统、选择冷热源和布置送、回风口时，必须充分考虑到酒店的这些特点，进行合理的设计。10795这次的设计内容是广州某五星级酒店 1-2 层和地下1 层的空调设计。2 工程概况 本工程位
2、于广州市,总建筑面积为 23639 平方米,总高度为 21.731 米,属多层建筑;地下共一层, 层高为-4.8米，设有棋牌包房、酒吧、KTV 包房，员工餐厅、办公用房、设备用房、厨房及洗衣房等；地上共五层，首层层高 5.4 米，二层层高 4.5 米，三 五层层高 3.9米。其中首层为西餐厅和接待厅;二层为会议室及按摩房;三五层为标准客房及行政套房，且五层还设有总统套房。3 设计主要内容结合建筑特点计算冷热负荷；冷热源方案确定；空调方案的确定；空调设备的选取（空调机组，冷水机组，排风、排烟风机等） ；风管水力计算；风管与风口的布置；防排烟的计算以及管道保温、减振和消声等内容。空调系统设计应用于
3、酒店建筑时，更要结合酒店的特点，使之符合风速、温度、湿度、及人的舒适性，有利于房客与酒店职工拥有更好的环境。所以充分考虑合理的气流组织、 温湿度及压力控制及节能措施，使设计更合理，更符合国家规范，满足业主要求。-范文最新推荐-3 / 443 冷热源方案由于本工程位于广州，地属冬暖地区，对于冬季热负荷需求不高， ，从经济运行角度，时间运行的角度，方便管理的角度，最大限度发挥能效的角度分析决定选用风冷式冷热水机组。选取开利风冷螺杆式冷水机组 30HXC400A 四台，两用两备。风冷式冷热水机组既供冷又供热，而且省去了锅炉房机组、冷却塔、冷却水泵和冷冻机房，节约了建筑投资和附加设备的投资。 根据高层
4、民用建筑设计防火规范的规定，在本设计中，在以下符合规定的房间设置防排烟：地下 1层的酒吧大厅、舞池、走道、机房和敞开办公室，1层的宴会厅，2 层的休息大厅。其余房间均采用自然排烟。7 风管与风口布置风管全部沿梁布置，全空气系统气流组织采用上送上回的形式。风口对气流组织有着关键影响，根据送回风量选择合适的风口，均匀分配，同时避免柱和梁的阻挡，最大可能的减少风量扰动对气流产生的负面效应，才能产生良好的气流组织效果。在本次设计中遵循平均布置的方法，使空调区域可以均匀送风。Design General Information1 The source of the designHotel is a st
