      空气净化工程应注意节能
      Energy saving in air purification engineering
      空调净化是一项能耗大的工程,在设计和施工中应注意节能措施。在设计,系统和地区部门,送风量计算,温度和相对湿度的测定,清洁水平的决心和空气变化,空气比,管道保温,风道咬形成的泄漏率,影响的主要分支连接空气阻力的影响,法兰接头是否漏气和空调箱,如风扇、冷水机等设备的选择与能耗有关,这些细节都必须加以考虑。
      Air conditioning purification is a project with large energy consumption. Energy saving measures should be paid attention to in design and construction. In design, system and regional departments, air supply calculation, measurement of temperature and relative humidity, determination of cleaning level and air change, air ratio, pipeline insulation, leakage rate caused by air duct bite, influence of air resistance of main branch connection, leakage of flange joint and selection of air conditioning box, such as fan, chiller and other equipment are related to energy consumption, these details must be considered.
      这种管道既需要经济又需要效率
      This kind of pipeline needs both economy and efficiency
      在集中或空调净化系统中,对管道的要求是经济和有效的空气供应。前者的要求体现在价格低,施工方便,运行成本高,内表面阻力小。后者是指严格良好,不漏风、不送尘、不收尘、不污染,可防火、耐腐蚀、耐湿。
      In the centralized or air-conditioning purification system, the requirement of the pipeline is economic and effective air supply. The requirements of the former are low price, convenient construction, high operation cost and small internal surface resistance. The latter refers to strict and good, no air leakage, no dust delivery, no dust collection, no pollution, fire prevention, corrosion resistance and moisture resistance.

      在运行中,有时管件的局部阻力远远高于管道沿程阻力,需要改进。管件主要有弯头、异径三通、四通等。弯头曲率半径应大于矩形管道的边长,圆形直径应为1.25倍。大截面风道应加导叶以减少阻力。但在实际安装施工中,这样的处理较少。对于渐缩管,不可能突然改变管径,宜采用渐缩管。渐缩管每边的伸缩角应大于15度,渐缩管每边的伸缩角应不大于30度。矩形风管的三通管应沿气流弯曲管进行弯曲划分,支管也应具有一定的曲率半径。如果要90度角分开,应在肘部用一个导叶。
      In operation, sometimes the local resistance of pipe fittings is much higher than that along the pipeline, which needs to be improved. Pipe fittings mainly include elbow, reducing tee, cross, etc. The radius of curvature of the elbow Center shall be greater than the side length of the rectangular pipe, and the circular diameter shall be 1.25 times. Guide vane should be added to large section air duct to reduce resistance. But in the actual installation and construction, such treatment is less. For the reducer, it is impossible to change the pipe diameter suddenly, so the reducer should be used. The expansion angle of each side of the reducer shall be greater than 15 degrees, and the expansion angle of each side of the reducer shall not be greater than 30 degrees. The tee pipe of rectangular air duct shall be divided by bending along the air flow bending pipe, and the branch pipe shall also have a certain radius of curvature. If you want a 90 degree angle separation, use a guide vane at the elbow.
      根据气候条件选择空调机箱
      Select air conditioning cabinet according to climate conditions
      关于空调箱的选择,应考虑气候环境。如果在冬天气温低,空气灰尘在北方,新的空气预热段应该添加到一般的空调机组,和喷水空气处理方式应采用使它不仅洗空气灰尘,也使它产生热量和温度交换达到所需的温度和湿度。在潮湿气候,南部地区的空气粉尘浓度很低,不需要预热新鲜的空气在冬天,空气过滤和温度、湿度调整主要是使用过滤,冷却表面温度和湿度的调整,也可以加强温度除湿过程,然后通过介质过滤效率和终端过滤效率或sub-high效率高。空调箱配套风机更好采用变频风机,这不仅节约能源,还能灵活调节风量风压。
      As for the selection of air conditioning box, the climate environment should be considered. If the temperature is low in winter and the air dust is in the north, the new air preheating section shall be added to the general air conditioning unit, and the spray air treatment method shall be adopted to make it not only wash the air dust, but also generate heat and exchange temperature to the required temperature and humidity. In the humid climate, the air dust concentration in the south is very low, and there is no need to preheat the fresh air in winter. Air filtration and temperature and humidity adjustment mainly use filtration, cooling surface temperature and humidity adjustment, and can also strengthen the temperature dehumidification process, and then through the medium filtration efficiency and terminal filtration efficiency or sub high efficiency. It is better to use variable frequency fan for the matching fan of air conditioning box, which can not only save energy, but also flexibly adjust the air volume and pressure.
      自动控制装置,充分调节
      Automatic control device, fully regulated
      目前,一些制造商使用手动模式来控制风量和风压调整,但由于控制风量和风压控制阀技术层,天花板也是彩色钢板软上限,主要是在安装和调试调整,因为,大多数没有调整,事实上不能调整。为保证无尘车间的正常生产和工作,应设置一套较为完备的自动控制装置,实现以下功能:空气清洁度、温湿度、压差监测、气阀调节;高纯气体、纯水、循环冷却水的温度、压力、流量检测;气体纯度、纯水水质监测。
      At present, some manufacturers use the manual mode to control the air volume and air pressure adjustment, but because of the control of air volume and air pressure control valve technology layer, the ceiling is also the soft upper limit of color steel plate, mainly in the installation and commissioning adjustment, because most of them are not adjusted, in fact, they cannot be adjusted. In order to ensure the normal production and work of the dust-free workshop, a set of relatively complete automatic control device shall be set to realize the following functions: air cleanliness, temperature and humidity, pressure difference monitoring, air valve regulation; temperature, pressure and flow detection of high-purity gas, pure water and circulating cooling water; gas purity and pure water quality monitoring.
      空调净化系统中的空气滤清器随着运行时间的增加而增大,需要调整系统中的空气阀以保持风量。系统调试时,为了使风机空载启动,需要关闭风机出风口的空气阀。风机启动后,由于气阀压力过大,很难启动风机。送风量调节方便,送风压力稳定。
      The air filter in the air-conditioning purification system increases with the increase of operation time. It is necessary to adjust the air valve in the system to maintain the air volume. During the system commissioning, in order to make the fan start without load, it is necessary to close the air valve at the air outlet of the fan. After the fan is started, it is difficult to start the fan due to the excessive pressure of the air valve. The air supply volume is easy to adjust and the air supply pressure is stable.
      这些监测装置可以设计为单一系统的测量和控制系统,也可以设计为分布式的计算机控制和管理系统。当空调净化系统关闭,无风、无超温时,电加热器会继续送电加热,造成设备损坏甚至起火。为了避免这种情况,应设置无风、超温断电保护。
      These monitoring devices can be designed as single system measurement and control system, or distributed computer control and management system. When the air conditioning purification system is closed, there is no wind or over temperature, the electric heater will continue to send electricity for heating, causing equipment damage or even fire. In order to avoid this kind of situation, no wind and over temperature power-off protection should be set.
      没有电话和火警报警设备
      No telephone and fire alarm equipment
      无尘车间内的电话和对讲机,可以减少洁净区域内的走动人数,减少粉尘量,并在发生火灾时及时与外界接触,为正常工作接触创造条件。另外,要建立火灾报警系统,防止火灾在室外难以发现,造成重大经济损失。
      The telephone and walkie talkie in the dust-free workshop can reduce the number of people walking in the clean area, reduce the amount of dust, and timely contact with the outside in case of fire, so as to create conditions for normal working contact. In addition, a fire alarm system should be established to prevent the fire from being difficult to be found outdoors and causing significant economic losses.
      多台冷水机更灵活
      Multiple chillers are more flexible
      如果冷水机需要较大的制冷量,则不宜选择单台冷水机。采用多机构,采用变频调速降低起动功率。许多机器可以灵活使用,以免浪费能源。
      If the chiller needs large cooling capacity, it is not suitable to choose a single chiller. Adopt multi mechanism and frequency control to reduce starting power. Many machines can be used flexibly to avoid wasting energy.
      空调室应在净化室的一侧
      The air conditioning room should be on one side of the purification room
      空调房的位置应在净化房的一侧,这样不仅可以节约能源,还可以方便风道的布置,使送风更加合理,同时可以节约工程成本。
      The air conditioning room shall be located on one side of the purification room, which can not only save energy, but also facilitate the arrangement of air duct, make the air supply more reasonable, and save the project cost.
