1、-范文最新推荐-1 / 17商业楼地上层空调通风设计+CAD 图纸空气调节系统是用人为的方法处理室内空气的温度、湿度、洁净度和气流速度的技术。可使某些场所获得具有一定温度和一定湿度的空气，以满足使用者及生产过程的要求和改善劳动卫生和室内气候条件。一般比较合理的流程是:先使外界空气与控制温度的水充分接触，达到相应的饱和湿度，然后将这饱和空气加热使其达到所需要的温度。当某些原始空气的温度和湿度过低时，可预先进行加热或直接通入蒸汽，以保证与水接触时能变为饱和空气。10182这次的设计任务是要完成浦南中心商业楼地上层的空调设计，设计任课题自实际工程。目的是通过本工程的设计，掌握空调系统的设计方法，设计
2、步骤；培养学生分析问题，解决问题的实际工程应用能力；加深对建筑空调工程专业知识的理解和记忆；掌握空调风管、水管、设备的选择和布置；掌握风管和水管的计算；增强绘图能力；培养分析问题、解决问题的实际工程应用能力，为将来从事室内环境设备工程和公共建筑的暖通空调设计，施工组织，运行管理工作奠定可靠的基础。2 工程概况该建筑位于上海市，采用的是新风加风机盘管空调系统。建筑面积约为 9600 平方米。共 4 层，每层层高为 4.8 米，为商业用房。3 设计依据3.1 设计任务书要求及所提原始资料1)工程地点：上海。各层建筑使用功能基本按照原图，1-4 层均为商业。2)依据自己设计计算的各层负荷、管路管径设
3、计绘图，将各层通风和水管平面图分别绘制。3)地下和地上层独立绘制各自对应的水系统图。-范文最新推荐-3 / 174)设备材料可在自己设计计算后，在原参考图纸中选择设备。 本建筑采用风机盘管加新风空调系统。由于空调房间较多，各房间要求单独调节，因此均采用风机盘管加新风空调系统。单设新风系统，独立供给室内，可随着室外气象变化进行调节，即把新风处理到室内参数，不承担房间负荷，保证室内湿度与新风量要求。这种方案既提高了该系统的调节和运转的灵活性，且进入风机盘管的供水温度可适当提高，水管结露的现象可以得到改善。6 空调水系统空调水系统设计原则是要考虑到以最简单的系统管路，力求水力平衡，要注意网管的防垢，
4、保暖和保冷的效果。按照供、回水管数量多少分为双管制、三管制和四管制。按照原理可分为开式和闭式系统。从建筑中可知，房间不需要同时供热和供冷，设计中管路不与大气接触，容易在最高点积存空气，所以选用闭式双管系统。冷热水共用一个管路，系统设置较为简单，初期投资较低。The general illustrate of design1 The source of designAir conditioning system is the treatment of indoor air by artificial method of the temperature, humidity, cleanliness
