What should I pay attention to in cleanroom design?
What should I pay attention to in cleanroom design?The design and construction of cleanroom is not as simple as it is imagined, it is a big project that needs to consume a lot of energy, especially air conditioning. Therefore, in the design and construction, attention must be paid to energy-saving measures, system and area division, good air volume calculation, and clear temperature and humidity demand. To ensure the whole process of clean room regulation, the air conditioning configuration with automatic control should be selected according to the demand and climate, and other conditions. In addition, the air-conditioning room should be designed in a clean room, which not only saves energy but also makes the airflow more reasonable.1. Clean room air design system The cleanroom air purification system of airflow distribution is broadly divided into horizontal laminar flow, vertical laminar flow, and turbulence. The airflow method is selected according to the routine, and the cleanliness is mainly determined by the number of air changes per unit of time. Therefore, before determining the technical parameters of the purification system, it is necessary to carefully consider the production needs of the clean room and the nature of the industry. 2. Clean room program design Before deciding the design of the clean room, need to carefully consider the nature of the industry and airflow conditions of the workshop installed. In a clean room with large dust emissions, do not use the ground air supply to avoid entering other workplaces that need to be clean. 3. Pressure and airflow Clean room to prevent outside air into the room, the room must maintain a positive pressure to achieve the purpose. To obtain the necessary indoor pressure, need to add appropriate fresh air. 4. Dust prevention for people and objects People and objects are the main source of dust and should be controlled. For example, before entering the clean room, everyone needs to change into clean dust-free clothes, shoes, and hats, good disinfection and cleaning, and accordingly, through the air shower room, and cargo shower room blowing into, to reduce the dust source of pollution. 5. Drainage, gas supply, power supply In the design process of the clean room, according to the actual situation inside the project and the specific requirements of the customer, do the above points. The design of the operation of the clean room should provide the required drainage devices, gas supply devices, and power supply. These devices and related equipment should be designed to be easy to use and not cause obstacles to the air purification system. |
