Purification works at all levels of air cleanliness of the air purification treatment, should be used early effect, efficiency, high efficiency air filter three filters. 100000-class air purification, can be used on behalf of the highly efficient air filter on behalf of the efficient air filter.
The choice of air filter installation and installation should be consistent with: early effect of air filter should not use oil-immersed filter; in effect air filter should be set in the purification of air conditioning system of positive pressure section; high efficiency air filter or Efficient and efficient air filter should be selected according to the rated air volume; resistance, efficiency, similar to the efficiency of the air filter should be installed in the end of the air purification system, high efficiency air filtration installation should be simple and reliable, should leak detection and replacement; Of the high-performance air filter should be set in the same purification plant.
Determine the centralized or decentralized clean air conditioning system, the production process should be integrated into the characteristics and cleanliness of the air purification plant level, size, location and other factors. Where the production process is continuous, clean room or purification plant area is larger, the location of concentration and noise control and vibration control requirements of the clean room, should adopt a centralized air purification system.
Clean air conditioning system For electric heating, should use tubular electric heater, the location should be arranged in the upper air side of the high efficiency air filter, and fire safety measures should be.
Blower can be purified air conditioning system, the total air supply and the total resistance value of choice, the efficiency and efficiency of the air filter resistance should be calculated according to its initial resistance twice.
Purification air purification system in addition to the DC system and set the system on duty fan should be taken to prevent outdoor air pollution through the new air intake into the clean room anti-pour measures.
Clean air conditioning system design should be a reasonable use of return air, where the process produces a large number of harmful substances and local treatment can not meet the health requirements, or harm to other processes, the return air should not be used.
