The main content includes: the load computation, the design and calculation of the air treatment process and the air flow, the selection of the equipments, the friction calculation of the wind and aqueous system and the determination of the systematic control strategies, etc. Combined with the specific characteristics of the architecture in the process of the design, the rational operation scheme should be formulated to make the system possess better functionality and operability in accordance with practical situation. The air-conditioning system is divided into two kinds: one is the system of primary air return, and the other is the system of the fan-coil unit with independent fresh air that the outdoor wind is treated to reach the indoor enthalpy, but not to bear the indoor load. In the refrigeration and thermal station, I adopt the screw water chiller to refrigerate in summer as well as the urban pipeline to transfer heat in winter through the plate heat exchanger. The generator room is fixed up in the basement, while the chilling tower is installed on the top of the podium of the building. As for the aqueous system, the closed, synchro, two-pipe and variant flow one is chosen.Keywords: Air-conditioning system Air treatment process The fan-coil unit with independent fresh air Plate heat exchanger目录引言 (1)1. 工程概况及原始资料 (2)1.1 工程概况 (2)1.2 气象参数 (2)1.2.1 室外计算参数 (2)1.2.2 室内设计参数 (3)1.3 建筑材料简介 (4)2. 负荷计算 (5)2.1 室内冷负荷计算 (5)2.1.1 墙体和屋面传热得热引起的冷负荷 (5)2.1.2 玻璃窗传热得热引起的冷负荷 (5)2.1.3 玻璃窗日射得热引起的冷负荷 (5)2.1.4 内维护结构形成的冷负荷 (6)2.1.5 照明散热引起的冷负荷 (6)2.1.6 人体散热引起的冷负荷 (7)2.1.7 设备散热引起的冷负荷 (7)2.1.8 室外新风引起的冷负荷 (8)2.2 室内热负荷计算 (13)2.2.1 通过围护结构的温差传热量形成的热负荷 (13)2.2.2 附加耗热量形成的热负荷 (13)2.2.3 外门开启冲入冷风耗热量形成的热负荷 (13)2.2.4 新风热负荷 (14)3. 空调方案的确定 (17)3.1 空调系统的分类 (17)3.1.1 按负担室内负荷所用介质种类分类 (17)3.1.2 按空气处理设备的设置情况分类 (18)3.2 空调方案的比较 (18)3.2.1 各种空调系统使用条件和使用特点 (18)3.2.2 常用空调系统比较 (19)3.2.3 空调系统使用指标概括比较 (21)3.3 空调方案的确定 (21)4. 风量计算 (24)4.1 送风量的确定 (24)4.2 新风量的确定 (24)4.2.1 满足卫生要求 (24)4.2.2 补充局部排风量 (25)4.2.3 保证空调房间的正压要求 (25)5. 空气调节设备的选择 (26)5.1 空气处理机组的选择 (26)5.1.1 空调机组选型方法 (26)5.1.2 空调机组选型结果 (26)5.2 风机盘管机组的选择 (27)5.2.1 风机盘管机组选型结果 (27)6. 空调系统的设计计算 (29)6.1 风系统的阻力计算 (29)6.1.1 风管设计的基本任务 (29)6.1.2 风管的选择 (29)6.1.3 风管内风速的选择 (29)6.1.4 气流组织和送风形式 (30)6.1.5 计算方法 (31)6.1.6 计算结果 (31)6.2 水系统的阻力计算 (33)6.2.1 水系统形式的分类 (33)6.2.2 水系统形式的确定 (34)6.2.3 计算方法 (34)6.2.4 冷冻水系统设计计算 (35)6.2.5 冷却水系统设计计算 (40)6.2.6 冷凝水系统管路设计 (40)7. 冷冻热力站设计 (42)7.1 水冷式冷水机组的选择 (42)7.1.1 制冷机组选择依据 (42)7.1.2 制冷机组选型方案 (44)7.2 板式换热机组的选择 (45)7.3 冷却塔的选择 (45)7.4 定压装置的选择 (46)7.5 集水器、分水器的选择 (47)7.6 软水器的选择 (47)7.7 软化水箱的选择 (48)7.8 除污器的选择 (48)7.9 泵的选择 (48)7.9.1 冷冻水泵选型 (49)7.9.2 冷却水泵选型 (49)7.9.3 水泵的配管 (50)8. 空调系统管道保温以及系统的消声与减震 (51)8.1 空调系统管道的保温 (51)8.2 空调系统的噪声控制 (51)8.3 空调系统的减震控制 (52)结论 (54)致谢 (55)参考文献 (56)引言目前我国中央空调行业正处于高速发展的成长期，但由于受价格、质量、服务及住房等诸多因素的影响，成长周期相对较长。
建环专业论文(5篇)
建环专业论文(5篇)建环专业论文(5篇)建环专业论文范文第1篇"空间环境设计'专业群由室内设计技术、环境艺术设计、室内装饰技术、装饰艺术设计四个专业组成，其中室内设计技术专业为专业群核心专业。
四个专业每年为长三角地区培育数百名室内设计、环艺设计、装饰设计、室内装饰等方面的人才。
在与学校合作的某毕业生数据调查讨论公司的讨论显示，由于现有专业课程设置的局限，培育出来的一些毕业生学问面过窄，学习力量和适应力量较差，不能适应用人单位的需要，也成为一个日益严峻的问题。
"开展高等职业院校重点专业群建设，有利于专业间形成合力，发挥专业的集群优势，提升服务产业的力量;有利于增加毕业生的岗位适应性和职业迁移力量，解决同学持续进展的后劲不足等问题。
'笔者认为，专业群建设要增加同学的岗位适应性和职业迁移力量，最基本落脚点，还是要体现在扎实推动专业群课程体系的构建这一环节上。
针对以上问题，我们提出了"一平台+四模块'的课程体系。
该课程体系是一种以平台为基础，以模块为拓展的课程体系，强调专业群内各专业界限的弱化。
二、专业群建设课程体系建设实施过程(1)专业群"一平台+四模块'课程体系的构建将在专业群建设与进展的统筹规划下进行从平台与平台，平台与模块，基础与专业，必修与选修，理论与实践，学问、技能与态度等多维度进行整合调整，明确每门课程、每个教学环节在课程体系中的地位与作用。
合理确定各类课程的学时比例和学分比例，实现整体优化，使整个课程体系能紧紧围绕专业群培育目标。
充分体现课程相互之间的主次关系、层次关系以及内在联系和相互协作。
(2)专业群的平台功能是"结构承重'室内设计等四个专业的核心力量、专业力量和基础培育要求打算了公共平台建立的厚度、宽度和强度，即能满意专业群同学在设计领域的审美素养、思维方法、职业精神、基础技能等的要求。
平台的层次则应相对简约，能够支撑各专业实现"宽口径、厚基础'的人才培育目标。

环保工程论文范文
环保工程论文范文环保工程论文范文环保工程论文范文第1篇1.1涉及行业多，范围广，工期长一般状况下项目建设中环保工程涉及的内容比较多，施工种类繁多，主要包括土建工程、钢结构工程、机械设备工程、电气工程、机电设备安装工程以及自动化工程等，并且各分项应用范围不同，如排水、供暖、通风以及电气等。
正是由于涉及到的工程范围比较广泛，相应的施工工期也就比较长，如电气设备安装就需要在土建、钢结构及相关附属设备安装到位后才可以安装。
并且环保工程尤其是污水处理工程中采纳生物法，其调试周期一般在三至六个月。
1.2技术水平要求高经济的进展和社会的进步对工程建设质量有了更高的要求，尤其是对于环保工程来说，对此方面的技术要求更为严格，渐渐有更多新型技术与工艺被应用到工程建设中，但是相应的施工难度也在不断增加，为满意项目施工精准度的需求，需要更进一步地做好安装项目管理，提高工程安装技术水平。
1.3质量验收严环保内容多，涉及的专业也比较多，这样在施工时就需要各个部门的相互协调。
另外，由于工种相对简单，并且各项资源呈现多样性，假如各部门之间协调管理不到位，很大程度上会影响到工程建设的进度与质量。
许多环保工程不仅要通过甲方制订的验收指标，而且还要通过当地环保主管单位组织的验收会议。
无形中，也增加了环保工程质量验收的难度。
2环保工程项目管理难点分析2.1进度管理环保内容众多，涉及到的环节也比较多，整个安装施工的过程相对简单，假如其中任何一个环节消失问题，将会对整个工程建设造成影响。
因此，在对环保工程进行项目管理时，应做好进度管理工作，避开施工过程中消失突发事故而影响项目进度，保证项目可以根据要求顺当施工。
通过对项目进度总目标的分析，来对项目管理以及进度管理来进行掌握，各部分之间相互协调，将环保与土建工程、机电安装工程等相结合，合理掌握工程项目进度。
2.2质量管理环保工程质量会受到各种因素的影响，例如原材料质量、施工工序、技术以及工艺选择等，施工时一般在工序确定后不会再发生转变，这就需要建立一个完善的质量管理体系来对施工质量进行掌握。

环境工程毕业设计优秀范文
环境工程毕业设计优秀范文随着工业化和城市化进程的加速，环境问题日益凸显，环境工程作为一门致力于解决环境问题的学科，其重要性不言而喻。
本次毕业设计旨在针对某一具体的环境问题，提出切实可行的解决方案，并通过实际的工程设计和数据分析来验证方案的有效性和可行性。
一、项目背景本次毕业设计选取的是某城市污水处理厂的升级改造项目。
该污水处理厂始建于 20 世纪 80 年代，采用传统的活性污泥法工艺，随着城市的发展和污水排放量的增加，现有的处理设施已经无法满足处理要求，出水水质不能达到国家排放标准。
此外，由于设备老化和运行管理不善，污水处理厂的运行成本较高，能源消耗较大，急需进行升级改造。
二、设计目标本次升级改造的主要目标是提高污水处理厂的处理能力和出水水质，使其达到国家一级 A 排放标准；同时，优化工艺流程，降低运行成本和能源消耗，提高污水处理厂的运行稳定性和可靠性。
三、工艺流程设计在对现有工艺流程进行详细分析和评估的基础上，结合国内外先进的污水处理技术和经验，本次设计提出了一种基于改良 A2/O 工艺的污水处理方案。
该工艺将缺氧区、厌氧区和好氧区进行合理的组合和优化，能够有效地去除污水中的有机物、氮和磷等污染物。
具体工艺流程如下：污水首先进入格栅井，去除较大的悬浮物和漂浮物；然后进入沉砂池，去除污水中的砂粒；接着进入初沉池，去除部分悬浮物和有机物；初沉池出水进入改良 A2/O 反应池，依次经过缺氧区、厌氧区和好氧区，完成有机物的降解、氮的去除和磷的去除；反应池出水进入二沉池，进行泥水分离，上清液达标排放，沉淀污泥一部分回流至反应池，另一部分进入污泥处理系统进行处理。
四、主要构筑物设计1、格栅井设计格栅井 2 座，采用人工格栅和机械格栅相结合的方式，格栅间隙分别为 20mm 和 5mm，能够有效地去除污水中的大尺寸杂物和悬浮物。
2、沉砂池采用平流式沉砂池，设计尺寸为 L×B×H ＝ 20m×5m×2m，有效水深为 15m，停留时间为 30s，能够去除污水中粒径大于 02mm 的砂粒。

XX大学本科生毕业论文开题报告建环专业毕业设计（酒店）指导书设计题目：XX农业银行商住楼空调设计一、任务要求1、完成商住楼空调设计施工图一套，及配套设计说明书；2、按照二、1～10项编写说明书，说明书要求写出英文摘要和参考文献；3、设计说明书要求书写工整，插图美观，数据引用需要注明出处。
二、设计步骤1、熟悉土建资料和酒店空调的设计规范；2、空调负荷计算；3、空调分区、方案的选择、空调方案的经济性比较；4、气流组织计算、空气处理计算、空调设备选择计算；5、水力计算、水泵选择；6、消声减震计算；7、管道保温计算；8、卫生间通风系统、大楼及中央空调系统防火排烟；9、中央空调系统对BAS的要求；10、施工图预算11、绘制空调设计施工图，包括（按照下列顺序编写图纸编号和目录）●首页图：包括设计施工说明，设备材料表，图纸目录●各层空调平面、剖面图●水系统图●机房平面、剖面图●机房系统图或系统原理图●非标设备制作及主要设备安装大样图摘要:本设计为广州中央空调系统工程设计，共十二层，地下两层，建筑总面积13000，空调面积6526.6，根据房间功能，全楼采用集中供给空调方式，制冷机组采用直燃型溴化锂吸收式制冷机组两台，型号分别为BZ-40单台制冷量分别为465KW.根据各不同功能房间，将该集中系统分为二种空调送风方式，高大空间如餐厅、活动用房等采用全空气系统，新风直接从室外引进与回风混合（一次回风）后送风；住户、公寓等采用了风机盘管加独立新风系统，新风机组从室外引入新风处理到室内空气焓值，风机盘管承担室内全部冷负荷及部分的新风湿负荷。
全空气系统选用圆型散流器平射流形式，而风机盘管加独立新风系统有百叶风口侧送和散流器平送的形式。
水系统采用闭式双管同程式，冷水泵三台，两用三备，；冷却水泵选三台，两用一备。
卫生间通风统一由排风扇接出，在末端安装止回阀。
楼梯间采用自然排风排烟；标准层以上由于小于500m2所以采用自然排风；地下室、设备房、一层及二层设置防排烟系统，，选用变速风机，平时排风，发生火灾时排烟。
空调水系统只设有一个系统，每层均设有回水同程管。

The gross floor area is about 13000m2,and the airconditioner area is about6526.6. The cold duty is 874kw, We choose 2 immediate-combustion and absorption LiBr, and the models are BZ40H.Their maximal burning of natural gas are 465kw when refrigerating; According to different functions, The first system is in the supplies air. The second system is in other little room. It adopts the PAU+FCU system. FCU system deals with the fresh air. PAU system carries on the whole cold duty and part wet duty. PAU+FCU systems can send air from the side and the upside; it uses the circular air diffuser to supply air. There are five water-cooling pumps; three can be used when summer, two of five are for using and another three are for preparing; in winter, two for using and one for preparing. The system in washroom can ventilate by itself. The system in the staircase and the standard floors can exhaust air and smoke by itself. The preventing and exhausting smoke system is used for the underground room, the equipment room and the first and second floor and it adopts the same way to exhaust air and smoke: choosing the dual wind velocity fans which exhaust air at ordinary times, while exhausting smoke when the fire disaster machine目录第1章气象资料
