[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] cleanroom air velocity airflow rate provisions discussed here refers to the clean indoor air velocity refrigeration room works, in other clean space airflow velocity when discussing the specific equipment that again. For turbulent flow clean room because the main mainly by dilution to reduce the degree of indoor air pollution, so the main ventilation frequency with this concept, rather than directly with the concept of speed, but the speed of the indoor air has the following requirements; (1) outlet outlet flow rate should not be too decontamination, and simple air-conditioned rooms compared for speed decay faster proliferation greater angle. (2) the level of blowing air speed (for example, when sending side reflux rate) should not be too large, in order to avoid blowing the return airstream surface particles, causing further pollution, this is generally not a big speed 0.2m / s. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] clean room in an accident caused by static electricity are the following; 1. Electrostatic shock caused by static electricity, causing insecurity and fear of people and can cause secondary damage (such as people due to electric shock and fell, fell again by injury); 2. Discharge current caused by electrostatic discharge, such as semiconductor devices can cause damage and malfunction, such as the 50 P- MOS circuit placed in a plastic bag, shake after several projects, the NAND gate 39 serious breakdown by meter , up to 78% failure rate of competing, this is because of the semiconductor device is very sensitive to electrostatic discharge; 3. Electromagnetic waves generated by electrostatic discharge can lead to noise and electronic instruments and devices malfunction; 4. Electrostatic discharge may cause luminescence sensitive photographic films such as limb damage; 5. Mechanical phenomenon of static electricity can cause clogged sieve dust, yarn confusion, uneven depth and print products pollution; plant cooling engineering | Tianjin Jinzhong Ji HVAC Engineering Company (certified) | Tianjin HVAC engineering from Tianjin Jinzhong Ji purification equipment Limited.
