The effect of flu fan filter selection in the electronics industry
The effect of flu fan filter selection in the electronics industryFFU clean module as the basic air conditioning purification system in the electronics industry usually has the disadvantages of large investment, high energy consumption, insufficient coordination capacity, difficulty in updating and debugging, long engineering construction time, and high cost of updating and reconstruction.And, ffu fan filter selection as an exhaust air module gets rid of the above shortcomings, and has been widely used in the purification projects of electronic devices around the world. Its use consists of the following parts Now, the FFU clean module power generation unit widely used in the electronics industry consists of the shell, turbine filter fan, high-efficiency air supply outlet, and its hydraulic control system, specifically, the built-in filter fan layer. Electronics industry characteristics of the project scale, the total area of indoor space in the clean room is large, the cleanliness level is high, especially the level of 100 levels, thousands of levels of more than one, the update is also very frequent. (1)FFU clean module generator set (2) fu fan filter selection of complete sets of equipment for the special type of main keel system (3)Refrigeration fan coil (or known as dry fan coil) (4)Fresh air system. The advantages of FFU purification modules include: (1) The FFU purification module system is convenient, easy to update, adjust the total number of exhaust modules at any time, anywhere, and change the room to send and exhaust air volume (ventilation). To save indoor space, an interior ceiling air supply static pressure box can be allocated to a variety of pipes, lighting fixtures, self-spraying, and electrostatic induction in the jointer. (2) The total area of the production workshop is large, long, large conveyance to the ventilation ducts, saving energy consumption. (3) Negative pressure sealing. In FFU action, do not have to worry about the leakage caused by poor installation of the filter. FFU and chiller coil auxiliary facilities in the electronic device industry site application, reduce the input primary exhaust air volume, it has the electronic industry processing process production of wet less characteristics and responsiveness. However, due to the dry environmental humidity regulations in the pharmaceutical industry, it is inappropriate to set up chilled fan coils. Generally, the cold load of the room is eliminated by increasing the exhaust air volume by 1 time. If a laminar flow hood is made using FFU fan filter selection, the air supply to the room of the system may be increased. |
