Cleanrooms are used in practically every industry where small particles can interfere with the manufacturing process. With the rapid development of the social economy, especially scientific experiments and high-tech production processes represented by bioengineering, microelectronics, and precision processing. Precision, miniaturization, high purity, high quality, and high reliability of product processing are proposed higher requirements. cleanroom provide an indoor production environment not only related to the health and comfort of employees’ production activities, but also related to production efficiency, product quality, and even the smoothness of the production process.
The key component of cleanroom is the High Efficiency Particulate Air (HEPA) filter where all air delivered to the room is passed through and particles that are 0.3 micron and larger in size are filtered out. Sometimes it may be necessary for an Ultra Low Particulate Air (ULPA) filter to be used, where more stringent cleanliness is needed. People, the manufacturing process, facilities and equipment generate the contaminants that are filtered out by the HEPA or ULPA filters.
No matter how the external air conditions change in the modular cleanroom, the room can maintain the characteristics of the cleanliness, temperature, humidity, and pressure as originally set. Today’s article, we will introduce four key elements of cleanroom design.
Cleanroom Architecture
Materials of construction and finishes are important in establishing cleanliness levels and are important in minimizing the internal generation of contaminants from the surfaces.
The HVAC System
The integrity of the cleanroom environment is created by the pressure differential compared with adjacent areas through heating, ventilation and air-conditioning system. The HVAC system requirements include:
1. Supplying airflow in sufficient volume and cleanliness to support the cleanliness rating of the room.
2. Introducing air in a manner to prevent stagnant areas where particles could accumulate.
3. Filtering the outside and re-circulated air across high efficiency particulate air (HEPA) filters.
4. Conditioning the air to meet the cleanroom temperature and humidity requirements.
5. Ensuring enough conditioned makeup air to maintain the specified positive pressurization.
Interaction Technology
Interaction technology includes two elements: (1) the movement of materials into the area and the movement of people (2) maintenance and cleaning. Administrative instructions, procedures and actions are necessary to be made about the logistics, operation strategies, maintenance and cleaning.
Monitoring systems
Monitoring systems include a means of indicating that the cleanroom is functioning properly. The variables monitored are the pressure differential between the outside environment and the cleanroom, temperature, humidity and, in some cases, noise and vibrations. Control data should be recorded on a routine basis.
Therefore, HVAC systems in cleanrooms are dramatically different from their counterparts in commercial buildings in terms of equipment design, system requirements, reliability, size and scale. But where can we find a reliable cleanroom solution provider that specialize in HVAC design?
