  • 集中空调与分散净化方式的介绍!

      分布式空调净化系统通常是指将热湿处理设备与粗、中、高效过滤器组合在一个箱内,分布在洁净室或相邻房间、走廊内的空调净化系统。有时空调机组只有粗效率和中效率过滤,但机组剩余压力大,克服了出口高效空气过滤器的阻力。此外,配有装配式洁净小房间等局部净化设备(洁净工作台、洁净棚、自洁装置),配有一般柜式、箱式、壁挂式小型空调系统也是这类。分散的一般成本更低,变化更灵活,改造项目更适合使用。GMP实施指南有以下规定。2.1.2.5“应使用集中空气净化系统适用于大面积、高洁净室、集中位置、噪声消除和振动控制要求高的洁净室,反之亦然。”
      Distributed air-conditioning purification system usually refers to the air-conditioning purification system that combines heat and humidity treatment equipment with coarse, medium and high efficiency filters in a box and distributes in the clean room or adjacent rooms and corridors. Sometimes the air conditioning unit has only coarse efficiency and medium efficiency filtering, but the residual pressure of the unit is large, which overcomes the resistance of the high efficiency air filter exported. In addition, it is equipped with local purification equipment such as assembled clean rooms (clean workbench, clean shed, self-cleaning device), general cabinet, box and wall-mounted small air conditioning systems. Decentralized general costs are lower, changes are more flexible, and transformation projects are more suitable for use. The GMP implementation guidelines have the following provisions. 2.1.2.5 "Centralized air purification system should be used in large area, high cleanroom, centralized location, noise elimination and vibration control requirements of clean rooms, and vice versa."
      净化空调机组配有冷却、除湿、加热加湿设备及粗、中、高过滤器时,可设置在洁净室外室或相邻走道内。将出风口管道连接到洁净室侧壁或天花板上,用网棚或其他扩压器向洁净室送风。从下侧壁返回到外室或走廊的空气与粗过滤的新鲜空气混合,吸入净化空调机组。新风应由带小风机和过滤器的新风机组送进,以保证外部或走廊与外部之间的正压。
      When equipped with cooling, dehumidifying, heating and humidifying equipment and coarse, medium and high filters, the purifying air conditioning unit can be set in the clean room outdoor or adjacent walkways. Connect the air outlet pipe to the side wall or ceiling of the clean room, and supply air to the clean room with a net shed or other diffuser. The air returned from the lower side wall to the outdoor or corridor is mixed with fresh air filtered roughly and inhaled to purify the air conditioning unit. Fresh air shall be supplied by fresh air units with small fans and filters to ensure positive pressure between the exterior or or corridor and the exterior.
      另一种情况是净化空调机组只有粗、中过滤,但有足够的剩余压力克服终的hepa阻力和管道阻力。此时,hepa可位于送风管道末端的出风口,更有利于保证送进洁净室的空气的清洁度。
      Another case is that the purifying air conditioning unit has only coarse and medium filtration, but there is enough residual pressure to overcome the ultimate HEPA resistance and pipeline resistance. At this time, HEPA can be located at the outlet at the end of the air supply pipeline, which is more conducive to ensuring the cleanliness of the air into the clean room.
      特殊的净化空调机组在中国没有固定的产品,其中大部分是由压缩机、蒸发器、冷凝器和其他备件购买由空调净化设备厂生产工厂,加上空气压力和较高的球迷更大的风量和各级过滤器,和盒子的身体重新设计和加工。空调是根据洁净室的冷热负荷选择的。另一个带介质过滤的增压风机箱与空调机组串联。回风大部分与增压风机箱连接回收,少量回风回空调机组,采用新鲜空气进行热湿处理。增压风机箱出水管将空气输送到洁净室顶棚高效过滤器风口,已在河北、山东、安徽、湖北、北京、天津等多家中小药厂使用。
    空气净化工程
      Special purification air-conditioning units in China do not have fixed products, most of which are purchased by compressors, evaporators, condensers and other spare parts by air-conditioning purification plant production plants, plus air pressure and higher fans of greater air volume and filters at all levels, and the body of the box redesigned and processed. Air conditioning is selected according to the cooling and heating load of the clean room. Another booster fan box with medium filtration is connected in series with the air conditioning unit. Most of the return air is connected with the booster fan box for recovery. A small amount of return air is returned to the air conditioning unit, and fresh air is used for heat and humidity treatment. The outlet pipe of supercharged fan box conveys air to the air outlet of high efficiency filter on the roof of clean room. It has been used in many small and medium-sized pharmaceutical factories in Hebei, Shandong, Anhui, Hubei, Beijing and Tianjin.
      一种是与风机-高效过滤器单元一起使用的方法。在我国,风机高效过滤器的进气口固定产品不多。其性质与给出的图例一致。笔者所参加的武汉某医科大学的制剂车间采用了这种方法。
      One method is to use with the fan-high efficiency filter unit. In our country, there are few fixed products for the inlet of fan high efficiency filter. Its properties are consistent with the illustrations given. This method was used in the preparation workshop of a Medical University in Wuhan.
      另一种是由空调机组、增压风机、中高效过滤器组成的水平单向流洁净室。天津大学承担的石家庄某电子研究所的±0.1℃、M3.5级恒温恒湿洁净室就是以这些形式实现的。
      The other is a horizontal one-way flow clean room composed of air conditioning units, booster fans and medium and high efficiency filters. The (+0.1 C) and M3.5 grade constant temperature and humidity clean rooms of an electronic research institute in Shijiazhuang, which Tianjin University undertakes, are realized in these forms.
      集中空调,分散净化
      Centralized air conditioning, decentralized purification
      当初的集中空调的房间需要净化,或考虑到噪音和振动的原因,空调净化模式结合集中式空调系统采用分散净化设备,也有灵活的使用和方便的转换的特点。为满足深圳两家医院生物洁净手术室和病房的需要,在手术室设计中采用了自净式手术室。分别给出了空调送风支路上的四种清洗台(a)、自净机(b、c)和高效过滤器风机(d)。
      When the original central air-conditioning room needs to be cleaned, or considering the reasons of noise and vibration, the air-conditioning purification mode combined with the centralized air-conditioning system adopts decentralized purification equipment, which also has the characteristics of flexible use and convenient conversion. In order to meet the needs of bio-clean operating rooms and wards in two hospitals in Shenzhen, self-cleaning operating rooms were adopted in the design of operating rooms. Four kinds of cleaning benches (a), self-cleaning machines (b, c) and high-efficiency filter fans (d) on air-conditioning feeder branches are given respectively.
      对于室内部分要求高洁净水平的场所,可以设置洁净室或洁净棚。在深圳某中医医院制剂室等制剂室,笔者多次采用单向清洗棚作为局部净化措施,取得了满意的实际效果。
      For places requiring high level of cleanliness in indoor parts, clean rooms or shed can be set up. In the preparation room of a traditional Chinese medicine hospital in Shenzhen, the author used the one-way cleaning shed as a local Purification Measure for many times, and achieved satisfactory practical results.
