In recent years, the use of chemical fiber industrial air conditioners - purification air conditioners has become more and more extensive in the fields of scientific research, medical treatment, high-tech product production, laboratories, electronic products, and precision instruments. The technical requirements and quality of the purification air-conditioning system are high, and the investment is large. If it fails, it will cause waste in terms of financial, material and human resources. Therefore, it is necessary to do a good job in clean air-conditioning system, in addition to perfect design drawings, high quality is required. High level of construction.

The material for making ducts is the basic condition for ensuring the cleanliness of air conditioners in chemical fiber industry.

Air duct material selection

Chemical fiber industrial air conditioning - purification air conditioning system duct is generally processed by galvanized steel. The galvanized steel plate should be made of high quality plate. The standard of galvanized layer should be >314g/m2, and the coating should be uniform, no shelling and no oxidation. Hangers, reinforced frames, connecting bolts, washers, duct flanges, rivets shall be galvanized. The flange mats shall be made of flexible rubber, non-dusting, soft rubber or latex sponge with a certain strength. The external thermal insulation Jincheng adopts rubber insulation board of 2.0, 2.5 and 3.0. Rubber and plastic insulation board has excellent fire performance, strong anti-seismic function, long service life, convenient and quick installation, and strong fireproof performance. It is recognized as a green environmental protection material.

Air pipe material procurement

Material procurement must be based on the product selected by the quality assurance manufacturer of the same product. In the physical inspection, attention should also be paid to the material specifications and material finish. The sheet should also be checked for flatness, corner angle, and adhesion of the galvanized layer. After the purchase of materials, the transportation should also pay attention to maintaining a good packaging, moisture, impact and pollution.

Air duct material storage

Chemical fiber industrial air-conditioning - materials for purification of air-conditioning should be set up in a dedicated warehouse, or centralized storage. The storage area should be clean, no pollution source, avoid moisture, especially the damper, tuyere, muffler and other components should be tightly packed and stored. Clean air conditioning materials should shorten the storage time of the warehouse, and should be used with the purchase. The panels used for the production of ducts shall be transported to the site to avoid contamination caused by the handling of the parts.

Smoke prevention in clean room

After the clean room is activated, it is generally in a positive pressure state, and the airtightness between the clean rooms is good. The flow of people and logistics is tortuous. Once the fire is found, it is difficult to evacuate and save. At the same time, because the heat of the fire source is not easy to be dissipated, the indoor materials are The object heats up quickly and is easy to catch fire to expand the fire surface.

At present, the national “Clean Plant Design Code” revised draft GB50073-2001 has strict regulations on clean room evacuation walkway, decoration materials and fire endurance, fire prevention, explosion-proof measures, fire valve setting, smoke control measures, Fire water supply and automatic spray have been specified. Therefore, the construction of the smoke control system for clean rooms must be carried out in accordance with the relevant regulations. It is important to note that the pipe and embedded parts for smoke control must be coordinated with the construction profession to ensure that there are no missing items.

Serious and orderly test, to ensure that the clean air conditioning system is successfully debugged once

Chemical fiber industrial air-conditioning - clean air-conditioning system must be cleaned and cleaned after the installation of air-conditioning room, air-conditioning room, all unrelated items must be removed, and carefully check whether the paint in the air-conditioned room and the wall, roof and floor of the machine room is damaged and compensated All, carefully check the filtration system of the equipment. For the end of the air supply system, the air outlet can be directly installed (the high-efficiency filter can be installed in the system with a cleanliness level of 6 or higher). Carefully check the electrical, automatic control system, and power supply system to confirm that the systems are intact. Test the car.

Develop a detailed test plan, arrange the personnel to participate in the test, and prepare the necessary tools, tools, and measuring tools.

The test drive must be carried out under unified organization and unified command. During the test run, the fresh air filter is replaced once every 2 hours, and the end of the high-efficiency filter should be replaced and cleaned regularly, usually once every 4 hours. The test run must be carried out continuously. The operation data can be obtained from the automatic control system to understand the data of each air conditioner room and equipment room, and the adjustment is implemented by the automatic control system. The time for purifying the air conditioning test run must meet the time specified in the GB50243-2002 specification.

After the trial operation, the system can be tested after the system has stabilized. Test contents include air volume (wind speed), static pressure difference, air filter leakage, indoor air cleanliness level, indoor floating bacteria and sedimentation bacteria, air temperature and humidity, indoor airflow manifold, indoor noise, etc., and can also be designed according to cleanliness. Levels or grades in the agreed acceptance state are required.

To ensure the success of chemical fiber industrial air conditioning - purification air conditioning system construction, the following principles should be grasped:

1. Strictly control the procurement of materials, and check the cleanliness of good processes.

2. Establish various systems to ensure clean air conditioning construction.

3. Strengthen the technical and quality education of construction workers.

4. Prepare all kinds of tools and equipment.
