Introduction to a Class 1,000 Clean Room
Tianjin Atson designed a Class 1000 cleanroom lab, with temperature control accuracy up to ±0.2°C and humidity accuracy up to ±2%, making it precise and controllable. Class 1000 cleanrooms are widely used in areas like microbiological testing, biopharmaceuticals, and microelectronics manufacturing.
A Class 1000 cleanroom means that the cleanliness level is 1000, which indicates that the number of dust particles with a diameter of 0.5 microns or larger in each cubic meter of air does not exceed 10,000. This level of cleanroom is usually used for experiments and production processes that require a highly clean environment, such as microbiological testing, biopharmaceuticals, and microelectronics manufacturing. In these fields, the cleanliness of the environment is extremely important, and a Class 1000 cleanroom can provide a stable, clean, and safe working environment.
Laboratory Cleanliness Classification
The cleanliness standards for laboratories are divided into four levels: 100, 1,000, 10,000, and 100,000.
1. Class 100 cleanroom
The number of particles in the air with a diameter over 0.5 μm must not exceed 3,520 per cubic foot, and the number of particles over 5 μm must not exceed 3.52 per cubic foot.
2. Class 1000 Cleanroom:
The number of particles in the air with a diameter over 0.5 μm must not exceed 35,200 per cubic foot, and the number of particles over 5 μm must not exceed 35.2 per cubic foot.
3. Class 10,000 Cleanroom:
The number of particles in the air larger than 0.5 μm should not exceed 352,000 per cubic foot, and the number of particles larger than 5 μm should not exceed 352 per cubic foot.
4. 100,000-level cleanroom:
The number of particles in the air with a diameter greater than 0.5 μm must not exceed 3,520,000 per cubic foot, and the number of particles with a diameter greater than 5 μm must not exceed 3,520 per cubic foot.
High-precision laboratory design——
Key points for designing a Class 1000 cleanroom:
1、Air purification system
The air purification system is the core, which includes the design of airflow, the installation of high-efficiency filters, and control of air changes. High-efficiency filters (HEPA or ULPA) can effectively filter particles in the air, ensuring the cleanroom's air quality. The number of air changes is designed according to the cleanliness level to make sure the air quality is maintained.
2、Temperature and Humidity Control
Maintaining a constant room temperature and humidity is very important for the proper operation of a Class 1000 cleanroom. Usually, the temperature in a cleanroom should be kept between 18-22°C, and the humidity should be controlled between 40-60%. This requires a precise temperature and humidity control system.
3、Airflow Layout Design
Airflow organization design includes two types: unidirectional flow (laminar flow) and turbulent flow (non-unidirectional flow). Unidirectional flow is suitable for areas with high cleanliness requirements, while turbulent flow is suitable for areas with lower cleanliness requirements. The specific choice should be determined based on the cleanliness requirements and the intended use.
Air conditioning system type:
The air conditioning system in a thousand-level cleanroom usually uses either a centralized or a decentralized system. Centralized air conditioning is suitable for multi-room, multi-requirement, clustered, and multifunctional cleanrooms. Its advantages are easy management, being away from noise pollution, and cost reduction. Decentralized air conditioning, on the other hand, is suitable for individual labs or small cleanrooms, focusing on precise control and stronger targeting.
Air purification:
The air conditioning system in a thousand-level cleanroom needs to have high-efficiency filters to make sure the air going into the lab is clean enough. Usually, the air purification system uses a three-stage filtration setup—primary, medium, and high efficiency—to keep the air clean.
Temperature and humidity control:
The temperature and humidity in a thousand-level cleanroom need to be strictly controlled. Usually, the temperature should be kept between 18-22°C, and the humidity should be controlled between 40-60%. This requires a precise temperature and humidity control system.
Pressure control:
To keep pollutants out of a clean lab, you need to maintain positive pressure inside with the air conditioning system. This is usually done by controlling the amount of air going in and out.
Airflow organization:
The airflow design in a thousand-level cleanroom needs to make sure the air flows from the clean area to the less clean area to keep contaminants out of the clean zone. This is usually done by positioning the air supply and return vents correctly.
Equipment selection:
When choosing air conditioning equipment, you need to consider factors like the lab's size, cleanliness requirements, and temperature and humidity needs. Usually, you want to pick AC units that have high-efficiency filters, precise temperature and humidity control, and low noise.
Safety considerations:
When designing the air conditioning system for a Class 1000 cleanroom, safety also needs to be considered. For example, an emergency exhaust system is needed to handle potential chemical gas leaks, and a backup power supply is required to ensure emergency ventilation in case of a power outage.
