Clean workshop construction, pay attention to details

Clean room after the opening was in positive pressure, and clean room airtight, the flow of people, logistics corridor twists and turns, once found the fire, evacuation, rescue is difficult, at the same time, due to the fire heat is not easy to radiate the indoor physical material, fast heating, easy to fire the fire disaster spread.

At present, the national "clean plant design specifications" revised GB50073-2001 to clean indoor evacuation corridors, decoration materials and the fire resistance limit of a strict, explosion-proof exhaust system fire prevention measures, fire valve setting, smoke control measures, fire water supply, automatic sprinkler have made specific provisions. Therefore, the construction of the smoke control system the clean room must comply with the relevant provisions of serious implementation, with particular attention to the pipe and embedded parts must be combined with smoke, and building out of phase synchronization, to ensure no leakage.

5., serious and orderly trial run, to ensure the clean air-conditioning system debugging success once

Must be 5.1 clean air conditioning system after the installation of air conditioning, air conditioning room clean, clean, all extraneous object must be removed, and carefully check the air-conditioning room and room walls, roof, ground paint damage and completion, filtration system carefully check the equipment, the air supply system can be installed directly (outlet end the cleanliness of the above 6 level system can be installed HEPA filter), carefully check the electrical, automatic control system, power supply system, confirm the system intact before commissioning.

5.2 make detailed test plan, arrange the personnel who take part in the test, and prepare the necessary tools, gauges and measuring tools

The 5.3 test must be in a unified organization, unified command. During the trial operation of air filter once every 2 hours, the end is equipped with high efficiency filters should be regularly replaced, cleaned, usually 4 hours at a time. Test run must be continuous, running from the solution of the air conditioning automatic control system, the data of real equipment the implementation of control system and the automatic control of clean air conditioning. Running time must comply with the requirements in GB50243-2002 specification.

5.4 after the trial operation, the system is stable after the test. The test content includes air flow (wind speed), differential pressure, air filter leakage, indoor air clean grade, planktonic bacteria and bacterial sedimentation chamber, air temperature and humidity, indoor air manifold, indoor noise index, also can design according to the cleanliness in the class or state level agreed acceptance requirements.

6. purification workshop construction example

Clean air conditioning system of our company in recent years according to the above method construction is successful, the cleanliness of the demand is higher, try the ideal adjustment effect is Zhejiang province Hangzhou electronics factory. The Engineering Department of Taiwan funded enterprises, clean air conditioning area of 6000 square meters, including 3000 square meters for computer Ruipian shell processing area, clean grade 7, + 0.2 DEG C, relative humidity + 5%. another 3000 square meters of assembly area for computer, cleanliness grade 6, plus or minus 0.02 DEG C temperature, humidity requirements + 1 per thousand. Cleanliness class 7 the air-cooled heat pump air conditioning, take back, use the clean air conditioner four (two by two). Cleanliness class 6 area using the DDC six control fan coil form. Fresh air by elevated floor within the interior into the fresh air, return air pipe in the column, each branch are equipped with an electric regulating valve for the engineering construction after careful self-control, Strict inspection, testing commissioning a successful class.6 clean air conditioning area after running at nearly 5 grade, 7 grade air conditioning area to reach 6 standards. The whole detection process employed by the owners Taiwan Party group, after the completion of the project owners are very satisfied.

In short to ensure clean air conditioning system in the construction of success, should grasp the following principles: 1 strict material purchasing process, good clean checks.2. establish the system to ensure clean air conditioning construction technology and quality education to strengthen the.3..4. construction of the preparation of the various hand tools.
