一、空调末端设备嘈声超标与处理
First, the air-conditioning equipment noise and exceed the standard treatment
空调末端设备运转嘈声超标，是实践过程中最经常碰到的设备嗜声问题。风机盘管由于技术等各方面比较成熟，国内的许多厂家的产品都能达标。而大风机组的情况却不尽如人意，往往嘈声实测值比厂家提供的产品样本参数高出不少。
The air-conditioning equipment operation noise is the sound most addicted to exceed the standard, often encountered in the process of practice equipment. Fan coil units are mature in many aspects, such as technology, and many domestic manufacturers can meet the requirements. The wind unit is not satisfactory, often the noise measured product sample parameters provided by the manufacturer is much higher than the.
我们接触过二例末端设备运转嘈声超标的工程：—个是吊式柜机的进出口都设有消声器，但设备本身的哈声超标太多而从回风口传出来；另—例是吊式柜机的进出口都没设消声器，结果试运转时室内的嘈声实测值远超有关的室内嗜声的标准。这二个工程最后都采用变频器降低风机转速来减少哈声，但空调的制冷效果也受到很大影响。
We contacted two cases of terminal engineering equipment operation noise exceed the standard: one is hanging cabinet is equipped with the import and export of muffler, but the device itself Kazakhstan sound too much and exceed the standard from the air return mouth; the other cases is hanging cabinet import and export are not a muffler test results measured indoor noise the value far exceeds the standard operation of indoor sound l.. The two projects finally use frequency converter to reduce the fan speed to reduce ha, but the cooling effect of air conditioning is also greatly affected.
因此，设计中要标出设备的嘈声参数要求，同时对大风量机组设计时应考虑消声隔声措施。在设备进场及时进行设备开箱检查，大风量机组未安装前最好进行通电试运行，发现心声超标问题可以及时进行更换、退货或修改完善消声措施等处理方法，避免安装后进人工程调试阶段才发现机组有嗜声问题而造成大整改情况。
Therefore, the noise parameters required to mark the equipment design, the design of large volume units should be considered when sound insulation measures. The equipment entering the timely equipment checking, wind unit is not installed before the best electricity test run, exceed the standard problem can be timely found heart replacement and return or modify the processing methods of noise reduction measures, avoid the installation of Engineering commissioning phase was found after the unit is addicted to problems caused by large acoustic rectification.
二、空调水系统的循环问题与解决
Two. Circulation problems and solutions of air conditioning water system
水系统在中央空调工程中是最主要也是最关键的环书，出现问题就会直接影响系统的正常工作。中央空调冷冻水系统缓常见的问题冷冻水系统管道循环不良。造成管路循环不良的原因一是管道因各专业管线文叉，施工中没有协调处理好，造成管网出现许多气囊现象，影响管网循环。二是空调水系统管道清洗工作不到位，直接造成空调水系统循环堵塞。
The water system is the most important and the most critical book in the central air conditioning project, and the problems will directly affect the normal operation of the system. The common problems of chilled water system in central air conditioning system are poor circulation of chilled water system. The main reason for the poor circulation of pipelines is that the pipelines are not coordinated and handled in the construction because of the professional pipelines and forks, and many air bags appear in the pipe network, which affects the circulation of the pipe network. Two is the air conditioning water system pipe cleaning work is not in place, directly causing air-conditioning water system Circulatory congestion.
根据多年的实践，笔者认为针对第一个问题，处理方法就是加强施工前管理，合理安排管线标高，尽量避免出现气囊现象，同时在不可避免气囊部位要设置排气阀，且将排气阀的排气管接至安全处，以利系统排气。
Based on many years of practice, the author believes that to solve the first problem, approach is to strengthen the construction management, reasonable arrangement of pipeline elevation, try to avoid the phenomenon of air, and to set up the exhaust valve in the air bag and the inevitable part of the exhaust valve exhaust pipe connected to the exhaust system to a safe place.
对第二个问题，应该从施工过程就耍做好几方面预防工作：首先是焊接钢管安装前必须用机械或人工清除污垢和锈斑，当管内外壁清理干净后，将管口封闭待装。管道施工过程中未封闭的管口要做临时封堵，以免污物进入，管道连接时要及时清理焊渣和麻丝等杂物。
On the second question, should from the construction process on the play do some preventive work: the first is the welded steel pipe must use mechanical or manual removal of dirt and rust before installation, when the outer wall of tube after cleaning the nozzle closure to be installed. In the process of pipeline construction, the unsealed pipe mouth shall be temporarily blocked so as to prevent dirt from entering. When the pipe is connected, the welding slag and hemp silk should be cleaned up in time.
第二，管网项部设自动或手动排气阀，管网的最低处安装—个比较大的排污阀。如排污阀阀门太小，排污效果差，清洗次数要多，如不在最低处，则排污不彻底。
Second, the pipe section is provided with an automatic or manual exhaust valve, and a relatively large drain valve is installed at the lowest point of the pipe network. If the sewage valve is too small, the sewage effect is poor, the number of cleaning more, if not at the lowest point, then the sewage is not complete.
最后，管网安装中应适当增设临时过滤器和旁通冲洗阀门，在连接设备之前，结合通水试压进行分段清洗以免污物堵塞设备。清洗工作完成以后，还要进行水系统循环试运行，其目的是将管网中的污物冲洗集中到过滤器，然后再拆洗过滤器清除污物。
Finally, the network installation should be appropriate to add temporary filter and bypass flushing valve, in connection with the equipment, combined with water pressure test for sub cleaning, so as not to dirt clogging equipment. After the cleaning is finished, but also for the circulating water system of trial operation, the purpose of which is to network in the dirt washed to filter, and then wash the filter to remove dirt.
三、安装不当产生的滴水结礴问题与处理
Three, installation of water caused by improper handling problems and node B
造成空调系统在调试和运行中滴水结睡问题原因很多，归纳起来主要有管道安装和保温二大方面的原因。管道与管件、管道与设备之间连接不严密，造成漏水主要原因有：管道安装没有严格遵守操作规程施工。管材管件材料质量低劣，材料进场时没有进行认真检查。系统没有严格按规范进行水压试验。
Causes the air conditioning system in the debugging and the movement, the dripping water knot sleeps the question many reasons, induces mainly to have the piping installation and the heat preservation two big aspects reasons. The connection between the pipe and pipe fittings, pipes and equipment is not tight, and the leakage is caused by the main reason: the installation of the pipe does not strictly comply with the operation procedures. Pipe and pipe fittings are of poor quality and materials are not seriously checked in. The system does not perform hydrostatic tests strictly according to specifications.
因冷凝水管安装不当出现常见问题有：
Because of the improper installation of condensate pipe, there are common problems:
(1)冷凝水管路太长，安装时与吊顶打架或坡度难保证甚至是冷凝水管倒坡，造成滴水现象：空调机组的冷凝水管因没有设水封而出现机组的冷凝水无法排除。
(1) condensate pipe installation and the road is too long, or even difficult to ensure that the ceiling fight slope is down slope caused by water condensate pipes, condensate pipe phenomenon: the air conditioning unit because no water seal and condensing water unit can not be excluded.
(2)以上冷凝水管施工中安装向题处理的办法就是冷凝水尽可能就近排放，以避免冷凝水管倒坡积水或与吊顶打架现象；柜机的冷凝水管应按机内的负压大小设水封，以使冷凝水排放畅通。
(2) to the installation problem processing way is condensed water discharged nearby above condensate pipe construction, in order to avoid the condensation water down slope water or fight phenomenon and ceiling; condensed water pipe should be the size of the negative pressure cabinet inside a seal, so that the condensed water discharge flow.
保温引起的主要原因有：保温材料的容重不足或保温材料的厚度不均，结果是运行时保温材料的外表面温度达到露点温度而产生结露。保温材料与管道的外壁结合不紧密。空调水管道的末端未做封闭处理，造成潮气俊人保温层导致结露滴水。穿墙处冷冻管滴水，主要原因是保温不严密或保温材料的防潮层破损。风栅盘管滴水盘排水口被保温材料等杂物堵住，且安装完后没有及时清理和做冷凝水管的灌、排水试验。吊式柜机、风机盘管滴水盘的保温材料受破坏造成滴水盘结露。
The main causes of heat preservation are as follows: the bulk density of insulating material is insufficient or the thickness of insulating material is uneven, and the result is that the temperature of the outer surface of the insulating material at the time of operation reaches the dew point temperature, and the condensation occurs. The insulation material is not close to the outer wall of the pipe. The end of the air conditioning water pipe is not closed, resulting in moisture, handsome insulation layer, resulting in condensation dripping. The main reason for the drip of the freezing pipe through the wall is that the insulation is not tight or the moisture-proof layer of the insulating material is damaged. The wind grid coil, the drip tray and the drain hole are blocked by the insulation material, etc. after the installation, the irrigation and drainage test of the condensed water pipe is not done in time. Insulation material hanging cabinet, fan coil disk damage caused by drip drip tray condensation.
针对这些问题，主要的解决办法：
In view of these problems, the main solution:
一是加强保温材料进场的检查。要加强施工前的技术交底和施工中检查，严禁用大保温套管套小管道，加强对弯头、阀门、法兰及设备接口处等细部的保温质量控制力度，确保保温层与管道的外壁结合紧密。
First, strengthen the insulation materials approach inspection. To strengthen inspection and construction technical clarification before construction, prohibit the use of high insulation sleeve pipes, strengthen insulation quality control strength on the elbows, valves, flanges and equipment interface detail, ensure the wall insulation and pipe tightly.
二是穿墙部位冷冻管加设保温保护套管，加强检查，确保穿墙部位保温层的连续性和严密性。
Two is through the wall, the freezing pipe adds the heat preservation protective sleeve, strengthens the inspection, guaranteed that passes through the wall the insulation layer the continuity and the tightness.
