Recommended design and construction of cleanrooms ranging from Class 100 to Class 100000, fully covered by Huajian Net
In high-tech industries such as semiconductors, biomedicine, and precision manufacturing, clean rooms are the core infrastructure that ensures product yield and process stability. According to the ISO 14644-1 international standard, cleanrooms are classified into multiple levels based on the concentration of suspended particles in the air, including levels 100 (ISO 5), 1000 (ISO 6), 10000 (ISO 7) to 100000 (ISO 8), etc. The demand for cleanliness varies significantly among different industries. As a leading domestic clean engineering service provider, Huajianjing has become the preferred partner for many enterprises to build high standard clean environments with its full level coverage of design and construction capabilities, modular technology system, and full lifecycle services.
1、 Classification of Cleanroom Levels and Industry Adaptability
The core indicator of a cleanroom is the diameter per unit volume of air, which is 0.1 μ m; The number of particles in m. The number of particles per cubic foot of air in a Class 100 workshop does not exceed 100, suitable for scenarios such as semiconductor wafer manufacturing and high-end optical component processing that are highly sensitive to pollution; Thousand level workshops are mostly used for the filling area of biopharmaceuticals and the assembly of medical devices; Ten thousand level workshops are commonly used in food packaging and cosmetics production; The 100000 level workshop is widely used in the manufacturing of ordinary electronic components and laboratory environments. Huajianjing can customize and match cleanliness levels for different industries through precise particle size distribution analysis and airflow organization simulation, avoiding over design or insufficient functionality.
Taking the semiconductor industry as an example, Huajianjing once designed a Class 100 clean room for a 12 inch wafer fab, using vertical unidirectional flow (Laminar Flow) technology and FFU (Fan Filter Unit) array to achieve laminar flow coverage of 99.97%, ensuring fine dust control for key processes such as photolithography and etching. In the field of biomedicine, its designed thousand level workshop effectively blocks the risk of cross contamination and meets GMP certification requirements through positive pressure gradient control and airtight partitions.
2、 Full process design and construction capability: closed-loop management from proposal to implementation
Huajianjing has built; Requirement analysis - scheme design - construction and installation - debugging and verification - operation and maintenance support; The full chain service system. In the design phase, the team used CFD (Computational Fluid Dynamics) software to simulate airflow distribution, optimize the layout of air supply and return ports, and avoid the generation of vortex zones; During the construction phase, BIM (Building Information Modeling) technology is used for 3D pipeline collision detection to reduce on-site rework rates; During the acceptance stage, 12 indicators such as particle counting, wind speed uniformity, and temperature and humidity stability are tested according to ISO 14644-3 standard to ensure one-time third-party certification.
In response to the economic needs of a 100000 level workshop, Huajianjing has developed a modular assembly type clean wall panel system, which can be quickly assembled through standardized components, reducing the construction period by 40%. At the same time, it adopts a detachable design for easy upgrading and renovation in the later stage. In a new energy vehicle battery factory project, this solution helped the customer save 23% of the initial investment cost.
3、 Core Technology Breakthrough: Dual Upgrade of Energy Conservation and Intelligence
The energy consumption of traditional clean rooms accounts for more than 30% of the operating costs of enterprises. Huajianjing has reduced the full life cycle costs through three major innovations: firstly, the development of low resistance high-efficiency filters (HEPA), which reduce the initial pressure difference by 15% and extend the replacement cycle; Secondly, the application of intelligent variable frequency air conditioning system dynamically adjusts the air supply volume according to real-time cleanliness requirements, achieving an energy-saving rate of 25%; Thirdly, deploy an IoT monitoring platform to collect real-time data on temperature, humidity, pressure difference, particle concentration, etc., predict equipment failures through AI algorithms, and achieve preventive maintenance.
In a certain thousand level biosafety laboratory project, Huajianjing's intelligent control system successfully reduced energy consumption from the industry average of 800W/m² Reduced to 580W/m² At the same time, negative pressure isolation technology is used to ensure zero leakage of pathogenic microorganisms, which has been awarded by the customer; Annual Best Energy saving Plan Award;.
4、 Full lifecycle service: commitment from delivery to continuous optimization
Huajianjing provides; 3-year free warranty+lifetime maintenance; Service, establish customer exclusive files, conduct regular follow-up visits, and issue cleanliness testing reports. Its 20 service outlets nationwide can achieve 48 hour emergency response, equipped with professional teams to handle sudden needs such as filter replacement and airtightness maintenance. In addition, in response to industry technological iteration, Huajian Net invests 5% of its annual revenue in research and development, and has accumulated 17 patents including energy-saving technology for clean rooms and anti-static floor structures.
From level 100 to level 100000, from solution design to operation and maintenance support, Huajianjing has built a complete ecosystem in the field of clean rooms with technical strength and service awareness. In the current transformation of the manufacturing industry towards high-end, its full level coverage capability is helping more enterprises break through the bottleneck of cleanliness and achieve a dual leap in quality and efficiency.
