Cleanroom engineering refers to the discharge of pollutants such as microparticles, harmful air, bacteria, etc. in the air within a certain air range, and the control of indoor temperature, cleanliness, indoor pressure, airflow speed and airflow distribution, noise vibration, lighting, static electricity, etc. within a certain demand range. We call such an environmental process a cleanroom project.
When judging whether a project needs a cleanroom project, you first need to understand the classification of cleanroom projects. Cleanroom projects are divided into mandatory and demand-based. For some specific industries, such as pharmaceutical factories, operating rooms, medical devices, food, beverages, etc., purification projects must be carried out under specific conditions due to mandatory standard requirements. On the other hand, clean rooms installed according to their own process requirements to ensure the quality of products or high-tech industries that need to be produced under purification conditions belong to demand-based cleanroom projects. At present, whether it is a mandatory or demand-based project, the application scope of purification projects is quite wide, involving medicine and health, precision manufacturing, optoelectronics, aerospace, food industry, cosmetics and other industries.
Professional organizations test purification projects covering wind speed and volume, ventilation times, temperature and humidity, pressure difference, suspended particles, floating bacteria, settling bacteria, noise, illumination, etc. These test items are highly professional and academic, and may be difficult for non-professionals to understand. Simply put, these contents cover HVAC systems, ventilation systems, and electrical systems. However, it should be made clear that cleanroom projects are not limited to these three aspects and cannot be equated with air treatment.
A complete cleanroom project involves more aspects, including eight parts: decoration and maintenance structure system, HVAC system, ventilation system, fire protection system, electrical system, process pipeline system, automatic control system, and water supply and drainage system. These components together constitute a complete system of cleanroom projects to ensure the realization of their performance and effects.
1. Decoration and maintenance structure system
The decoration and decoration of cleanroom projects usually involves specific decoration of systems of enclosure structures such as floors, ceilings, and partitions. In short, these parts cover the six faces of a three-dimensional enclosed space, namely the top, walls, and ground. In addition, it also includes doors, windows, and other decorative parts. Unlike general home decoration and industrial decoration, cleanroom engineering pays more attention to specific decoration standards and details to ensure that the space meets specific cleanliness and hygiene standards.
2. HVAC system
It covers cold (hot) water units (including water pumps, cooling towers, etc.) and air-cooled pipe machine levels and other equipment, air conditioning pipelines, combined purification air conditioning boxes (including mixed flow section, primary effect section, heating section, refrigeration section, dehumidification section, pressurization section, medium effect section, static pressure section, etc.) are also taken into account.
3. Ventilation and exhaust system
The ventilation system is a complete set of devices consisting of air inlets, exhaust outlets, air supply ducts, fans, cooling and heating equipment, filters, control systems and other ancillary equipment. The exhaust system is a whole system consisting of exhaust hoods or air inlets, cleanroom equipment and fans.
4. Fire protection system
Emergency passages, emergency lights, sprinklers, fire extinguishers, fire hoses, automatic alarm facilities, fireproof roller shutters, etc.
5. Electrical system
Including lighting, power and weak current, specifically covering cleanroom lamps, sockets, electrical cabinets, lines, monitoring and telephone and other strong and weak current systems.
6. Process piping system
In cleanroom project, it mainly includes: gas pipelines, material pipelines, purified water pipelines, injection water pipelines, steam, pure steam pipelines, primary water pipelines, circulating water pipelines, emptying and draining water pipelines, condensate, cooling water pipelines, etc.
7. Automatic control system
Including temperature control, temperature control, air volume and pressure control, opening sequence and time control, etc.
8. Water supply and drainage system
System layout, pipeline selection, pipeline laying, drainage accessories and small drainage structure, cleanroom plant circulation system, these dimensions, layout and installation of drainage system, etc.
