1、 中央空调安装调试难点分析及处理措施中英文对照Analysis and treatment measures of difficult installation of central airconditioning engineering随着经济建设的不断发展和人们生活水平的不断提高,中央空调系统已经成为大型建筑和办公环境不可缺少的重要设施。中央空调的效果如何?能否满足所需?除设计和施工外,关键的一环,在于安装调试工作的质量,它将直接影响空气调节的使用效果。本文就中央空调工程安装调试过程中的难点进行分析,并根据问题原因提出一些处理措施,以便进一步提高中央空调工程安装调试质量,发挥中央空调应有的
2、效能。With the development of economy and the improvement of peoples living standard, the central airconditioning system has become an indispensable important facilities of large buildings and office environment。 How the central air conditioning effect? To meet the need? In addition to the design and c
3、onstruction, key ring, lies in the installation and debugging work quality, it will directly affect the air-conditioning effect. Difficulties in central air-conditioning engineering installation process are analyzed, and puts forward some measures according to the problems, in order to further impro
4、ve the quality of installation of central airconditioning engineering, play a central air conditioning effectiveness。1。空调系统结露空调系统在运行中发生结露,导致出现风管及吊架结露、风口滴水、天花滴水、墙面渗水发霉、墙面涂料脱落等现象,虽然不会造成太大的事故,但已经影响到了观感和使用功能,给用户使用和大楼物业管理带来许多不便,并造成了一定的经济损失。其原因为保冷施工不规范,保冷层厚度不达标,保冷措施未发挥作用等等。因此,保温保冷的施工应聘请技术过硬的施工队进行施工。1 air
5、conditioning system of dew condensation in the operation of the air conditioning system, led to the emergence of wind pipe and outlet water, condensation, hanger ceiling dripping, wall seepage moldy, wall paint off phenomenon, although not cause too much of the accident, but has affected the percept
6、ion and use function, the use and the building property management to bring a lot of inconvenience, and caused a certain economic loss. The reason for the cold non-standard construction, cold layer thickness is not standard, cold measures does not play a role. Therefore, construction of thermal insu
7、lation cold for the construction team please skilled construction。1.1风管的处理:目前中央空调风管主要有无机材料复合风管和镀锌铁皮风管两种。无机材料复合风管由两层高轻度无机材料夹一层保温材料复合而成,具有质量轻、不燃烧、造价低,成品板材现场切割制作、安装比较方便等特点,保温层一般为2cm厚聚苯烯泡沫。由于材料结构比较合理,一般很少出现结露现象,施工前应重点检查板材有无剥壳、胀板变形等情况。1.1 wind pipe processing: the central air-conditioning duct mainly ino
8、rganic material composite wind pipe and galvanized iron duct two。 The inorganic material composite wind pipe consists of two floors with mild inorganic material with a composite layer of insulation material, has the advantages of light weight, not burning, low cost, finished plate making, field cutt
9、ing installation more convenient, the insulation layer is generally 2cm thick polystyrene foam. Because the material structure more reasonable, rarely dewing phenomenon, should focus on examination of sheet has no peeling, bilge plate deformation before construction。 1。2空调水管道的处理:空调水管道温度低,出现结露的概率比较大,
10、需要重点处理。施工时需严格控制供、回水及冷凝水管道和其他管道、风道、梁、柱、墙体之间的距离,常规距离控制在15cm以上,以便于保温工程的施工及确保保温质量,对于管道与支、吊架接触部位,正常情况下需增加木瓦管托,如无条件,也可以局部裹贴橡塑发泡板,再用卡箍收紧.同时需要注意各条管线应单独进行绝热施工.1。2 air conditioning water pipeline: air conditioning water pipe temperature is low, there is condensation probability is big, need to focus on treatm
11、ent. When construction should strictly control the supply, between water and condensate water pipeline and other pipelines, ducts, beam, column, wall distance, normal distance control in 15cm above, in order to facilitate heat preservation project construction and ensure that the insulation quality,
12、 for the pipeline and branch, hanger contact site, under normal circumstances should increase shingles pipe support, such as no conditions, can also partially coated rubber and foam board, and then tighten the clamp. At the same time the need to pay attention to each line should be insulated constru
13、ction alone。1。3死角部位的处理:风道、水管紧贴梁底、墙边及穿墙的部位也是保温施工的关键部位,如正常施工有困难,可以先在这些部位做好简易模具,再采用局部聚氨酯发泡填充,在风道、水管与障碍物接触周边表面形成保温层,以此隔离死角部位与空气的接触。1.3 corner parts of the key parts of air duct, water pipe: close to the bottom of beam, wall and wall part is insulation construction, such as the normal construction diffic
14、ulty, can be the first to die in these parts, and local polyurethane foam filling, in the air duct, water pipe and the barrier is formed on the surface of the contact perimeter insulation layer, in order to isolate dead parts and air contact。1。4送风口的处理:一般而言,相对封闭或面积较小的房间及走道的送风口出现结露的可能性较大,梅雨季节尤为明显,分析原因
15、主要有以下几点.Treatment of 1。4 inlets: Generally speaking, the room and corridor relatively closed or smaller outlet dewing possibility is larger, the rainy season is particularly evident, analysis the main causes are as follows.空调区域内的空气相对湿度大:夏季,特别在梅雨季节或者雷雨天,空气相对湿度大,水蒸气多,空调送风口很容易产生结露现象。The air conditionin
16、g area the air relative humidity: summer, especially in rainy season or thunderstorm days, air relative humidity, water vapor, the air outlet is easy to produce condensation.空调送风温差大:在某些时段,冷水温度比较低,而风机送风量又偏小,引起送风温差偏大,从而出现结露现象.这时可以适当手动调小风机盘管末端进水阀开度,加大风机送风量,从而减小送风温差。The air temperature: at certain hours
17、, cold water temperature is relatively low, and the fan air volume is small, cause the supply air temperature difference is too large, resulting in condensation。 At this time can be manually adjustable small fan coil end inlet valve opening, increase the fan air flow, thereby reducing the supply air
18、 temperature difference.送风口为铝合金材质:目前空调风口大部分采用铝合金材料制作,由于是金属表面,结露会比较严重.在购置风口时应注意:a)委托生产厂家在铝合金表面进行喷塑处理,降低风口表面温度;b)在风口法兰边后侧敷贴PE保温条,减少气流与风口的换热。由于空调送风量大、温差小,送风口出现结露现象的概率比较小。The air outlet for aluminum alloy material: the current air conditioning most of the use of aluminum alloy materials, due to the meta
19、l surface, condensation will be more serious。 Should pay attention to in the purchase of air: a) commissioned by the manufacturers to spray on the surface of aluminum alloy tuyere, reduce surface temperature; b) PE insulation strip attached to the outlet flange back side dressing, reduce the heat fl
20、ow and air。 Because the air volume large, small temperature difference, the probability of outlet condensation is relatively small.2。空调器噪声大、有振动The 2 air conditioner noise, vibration集中空调末端设备一般有组合式空调机组、柜式变风量空调器及风机盘管3种.风机盘管体积较小,出现问题的概率小;组合式空调机组、柜式变风量空调器由于体积大,机械设备功率大,出现问题的概率较大,需要逐步排查。Central airconditio
21、ning end equipment generally have a cabinet type air conditioner sets, VAV air conditioning and fan coil unit 3. Fan coil has the advantages of small volume, small probability of occurrence problem; cabinet combined type air conditioning units, VAV air conditioner due to large volume, mechanical equ
22、ipment power, the greater the probability problem, need to gradually investigation。2。1检查设备内部:系统调试前,按规定必须进行单机试运转,检查项目包括:空调器内部有无施工残留物,减振器或垫块是否安装到位,底脚螺栓和相关紧固件是否拧紧,风机叶轮是否摩擦蜗壳,轴承是否有润滑油,电动机皮带松紧如何等等,以保证设备自身有良好的运行条件。2.1 internal inspection equipment: before debugging, standalone commissioning required by th
23、e regulations, inspection items include: the air conditioner has no construction residues, shock absorber or block is installed in place, the foot bolt and the associated fastener is tightened, the fan impeller friction worm shell, bearing for lubrication, the motor belt. How to wait, to ensure that
24、 the equipment has good operating conditions.2.2检查所有与空调器连接的部位是否有软接头:空调水管与空调器连接必须采用可曲挠法兰橡胶软接头。风管与空调器连接部位需安装静压箱,静压箱的主要作用有两点:降低送、回风气流噪声;合理混合并分配气流。静压箱与空调的连接可以用铝箔复合通风软管,也可以用三防帆布软接头.2.2 check all parts connected with the air conditioner is a soft joint: air conditioning pipe and air conditioner connecting
