2. Carefully plan the purification system, including the precise positioning of air supply outlets, air return outlets, and exhaust outlets, the selection of air filters (a combination of primary, medium - efficiency, and high - efficiency filters to meet the Class 100,000 purification standard), and the accurate calculation of fresh air volume and air change rate to ensure that the indoor air continuously meets the aseptic requirements.
C. Material and Equipment Selection and Procurement
1. Strictly select building materials that meet the quality standards of the SGS Class 100,000 sterile room according to the design plan. For walls, choose color - coated steel plates with excellent air - tightness, smooth surface, and easy - to - clean properties; for the floor, use anti - static, corrosion - resistant, and seamless epoxy self - leveling materials.
2. Carefully select purification equipment. From fans, air - conditioning units to air purification devices, all choose well - known brands in the industry with excellent performance and products that have passed strict tests to ensure the stable operation of the equipment and lay the foundation for the long - term and efficient operation of the sterile room.
III. On - site Construction Stage
A. Basic Engineering Construction
1. First, carry out ground treatment. Grind and clean the original ground to ensure that there is no dust or oil residue. Subsequently, lay the anti - static epoxy self - leveling floor, strictly controlling the flatness error within a very small range to ensure the stable installation of subsequent equipment.
2. Build the wall framework according to the design requirements. Use high - quality aluminum alloy or light - steel keels to ensure the structural strength. When installing the color - coated steel plate walls, pay attention to the tightness of the plate joints and seal them with professional sealants to prevent air leakage.
B. Installation of Purification System
1. Install the air supply and exhaust ducts. The duct materials are selected from high - quality galvanized steel plates or stainless - steel plates with a smooth inner wall to reduce air resistance and the risk of dust accumulation. Connect the ducts in strict accordance with the specifications to ensure airtightness. During the installation process, conduct light - leakage detection at any time to discover and correct problems in a timely manner.
2. Install the primary, medium - efficiency, and high - efficiency air filters in sequence. Check the integrity of the filters before installation. Handle them with care during installation to avoid damage, ensuring that the gaskets fit tightly and the filtration efficiency meets the standards. Install the fans and air - conditioning units simultaneously, adjust the fan speed and air pressure, and calibrate the temperature and humidity control parameters of the air - conditioner to make the purification system operate in coordination.
C. Installation of Electrical and Lighting Systems
1. Lay cables and wires according to the electrical design drawings. Adopt the concealed wiring method through pipes. The pipe materials are selected from fire - resistant and corrosion - resistant PVC pipes or galvanized steel pipes to prevent safety hazards caused by exposed wires.
2. Install lighting fixtures. Select glare - free and evenly illuminated clean fluorescent lamps or LED lamps to meet the lighting needs of different areas in the sterile room. The installation of the lamps is well - sealed and easy to clean. At the same time, equip an emergency lighting system to ensure the safe evacuation of personnel in case of a sudden power outage.
D. Detail Optimization and Improvement
1. Install doors and windows carefully. Select air - tight doors, install door closers and access control systems to ensure smooth opening and closing and strong airtightness. Use double - layer insulating glass for windows, which not only meets the lighting requirements but also blocks external pollution.
2. Install water supply and drainage pipes. Select stainless - steel pipes that meet the hygienic standards as the pipe materials. Set up reasonable water seals and traps to prevent the back - flow of odors and microorganisms, ensuring the safety and hygiene of water use and drainage.
IV. Commissioning and Testing Stage
A. Purification System Commissioning
1. Start the purification system and gradually adjust parameters such as fan speed, fresh air volume, and return air ratio. Observe the indoor air flow pattern. Use methods such as smoke testing to visually check whether the air flow is uniform and free of turbulence, ensuring that the air circulation mode meets the requirements of the Class 100,000 purification standard.
2. Commission the air - conditioning unit. Accurately calibrate the temperature and humidity sensors to keep the indoor temperature and humidity stable within the specified range, such as a temperature of 18 - 26°C and a humidity of 45% - 65%, creating a comfortable environment for aseptic operation.
B. Testing and Acceptance
1. Entrust a professional third - party testing agency to comprehensively test the sterile room according to the SGS standards and relevant national standards. This includes air cleanliness testing, using a dust particle counter to measure the concentration of particulate matter of different particle sizes; and microbial testing, analyzing and evaluating the degree of microbial contamination through the sampling of sedimentation bacteria and planktonic bacteria.
2. Test items such as electrical safety, lighting illuminance, and grounding resistance to ensure that all indicators meet the specifications. Only when all test items are qualified can the sterile room be officially delivered for use.
V. Post - project Maintenance Stage
A. Regular Equipment Maintenance
1. Develop a detailed maintenance plan for purification equipment. Regularly maintain equipment such as fans, air - conditioning units, and air filters. For example, check the wear of fan bearings every quarter and replace the high - efficiency air filters every year to ensure the continuous stable performance of the equipment.
2. Establish an emergency response mechanism for equipment failures. Equip professional maintenance personnel who can respond quickly in case of sudden equipment failures and restore the operation of the sterile room in the shortest possible time to reduce production losses.
B. Environmental Monitoring and Continuous Optimization
1. Continuously monitor the air quality of the sterile room. Regularly sample and test the number of dust particles and the content of microorganisms. According to the monitoring results, adjust the parameters of the purification system or take cleaning and disinfection measures in a timely manner to keep the indoor environment in line with the Class 100,000 aseptic standard at all times.
2. Collect user feedback, optimize and upgrade the layout and functions of the sterile room, and continuously improve the user experience to meet the development needs of the industry.
