When we arrange the fume hood in the laboratory, we must pay attention to the rationality of the location, because some components may affect the use of the fume hood. For example, adjusting the door may affect the airflow of the fume hood.
When laying out the laboratory, the supply air flow and disturbance by personnel to the air inlet of the fume hood adjustment door should be minimized. The laboratory air supply volume is large. The laboratory air supply port can use an orifice plate static pressure box air supply port to expand the air supply port area and control the air supply orifice plate outlet wind speed. The air supply speed in front of the fume hood should be adjusted to <0.25m/s. The operating channel in front of the fume hood should be spacious. When operators move around, they should be at least 0.6m away from the fume hood panel to prevent personnel from affecting the airflow of the fume hood. The fume hood adjustment door should be kept away from the laboratory door to avoid opening the door and affecting the air flow of the fume hood.
The laboratory ventilation control system should meet the ventilation control needs. When used in the laboratory ventilation system, it can control the average surface wind speed at the entrance of the fume hood and the laboratory pressure, thereby achieving safe and energy-saving operation results.
