As the buildings air conditioning system using water-pressure gas tank closure expansion tank means constant pressure. Taking into account the simple design of the pipe line system, the design of wate


As the building's air conditioning system using water-pressure gas tank closure expansion tank means constant pressure. Taking into account the simple design of the pipe line system, the design of water systems in a dual-tube. Rooms vary for the horizontal part of program, namely for, the backwater stem the flow of the opposite direction, each Yi Huanlu ranging from the length of the pipeline, without the return by the way, tubes shorter length, the pipeline simple vertical for the same Program, that is, that is, for, backwater stem the flow in the direction of the same, after each Yi Huanlu the same length of pipe, use of the way so that water distribution, regulation of convenient.
Conversion to take the season points, catchment on a valve switch. Air-conditioning units and fan coil back on the water pipes for electric two-valve, air-conditioning load in accordance with changes in regulation of water through the coil, at the catchment-based electric pressure difference between the bypass valve to maintain pressure on the balance system.
7 Bathroom ventilation design
    The project room toilet located mechanical ventilation devices, set exhausting-fan, the ventilation of toilet by 20-30 m3 / h. Windowless bathroom set up  exhaust-opening, exhaust duct from the same access to, from exhaust to the outdoors-row. And around the external walls and windows of a bathroom, directly into the outdoors. Toilet maintain negative pressure to prevent the leakage of odors and toilet optional and exhausting-fan check valve.
暖通空调设计主要是对室内热环境、空气品质进行设计,但这必须在充分了解建筑对暖通空调的要求和暖通空调系统及设备对建筑及其它设施的影响的基础上进行设计。
这次的设计任务是要完成上海益柏大厦的空调设计,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。4610
2 工程概况
该建筑位于上海市,为上海益柏大厦空调系统设计,总建筑面积为7800平米。其中包括地下一层和地面十层。地下一层主要为仓库和设备房,一到三层为餐厅、包厢等用房,四到九层为酒店客房,建筑高度为36.6米。本次的空调设计主要是针对地面以上的空调房进行空调系统的设计。
3 设计依据
3.1 设计任务书要求及所提原始资料
根据建筑物性质、用途及建设单位要求,对上海益柏大厦具体进行的设计如下:
1)负荷计算(主要进行逐时冷负荷计算)
2)空调风系统设计:根据实际情况选择适合该建筑的系统
3)空调设备的计算选型:包括风机盘管的选择计算,空调机组和新风机组的选型计算等
4)空调水系统和风系统的设计计算:包括水系统管路的设计、风机盘管和空调机组的布置
4 设计的主要工作
结合建筑特点选择空调方式;计算冷热负荷;进行风管水管布置并进行水力计算;分别列出各管路的水利计算表。根据水力计算选择空调设备,包括空调机组、新风机组、风机盘管、风口等设备。
5 空调风系统
一到十层的全部采用风机盘管加新风空调系统。由于这些空调房间较多,面积相应较小,各房间要求单独调节,且房间温、湿度要求不严格,因此均采用风机盘管加新风空调系统。4~9层标准客房均按约面积划分控制单元、设置供回水回路以便于检修和文护。 上海大厦暖通空调工程设计计算书+CAD图纸(3):http://www.751com.cn/gongcheng/lunwen_1356.html
