    Column overview

    With the increasing investment in medical research and development in China, there are more and more laboratory projects, and the requirements of the laboratory for cleaning, pressure, ventilation and airflow are different, which meet different design requirements, while ensuring the stability and flexibility of the automatic control system. Combining with many years of practical experience in the industry, we have launched a solution based on laboratory automatic control to realize a variety of practical applications Monitoring and management of laboratory production and equipment.

    Solutions
    Differential pressure control

    Objective: to establish an orderly airflow direction, ensure the airflow from high cleanliness to low flow, reduce and isolate cross contamination. According to the specific needs of ventilation, the differential pressure control scheme is formulated to meet different needs. Make logical interlock and standby scheme according to process conditions.

    • Supply air frequency conversion constant air volume control, return exhaust manual butterfly valve air distribution, meet the low demand of differential pressure control.
    • The supply air is controlled by variable frequency and constant air volume. The return air adopts CAV (constant air volume valve), the specific function room automatically controls the exhaust VAV (variable air volume valve) according to the pressure, and the fresh air is adjusted according to the static pressure PID of return air to meet the demand of variable exhaust air (fume hood, etc.) but with low pressure difference.
    • The supply and exhaust air is controlled by variable frequency static pressure. The supply and return air adopts CAV (constant air volume valve), and the room and corridor automatically control the exhaust VAV (variable air volume valve) according to the pressure, so as to meet the requirements of clean areas with high pressure difference.
    • When there are energy-saving requirements (duty mode, etc.) of the system or area, according to the situation, increase the configuration of return exhaust VAV control.
    Wind speed control of ventilation cabinet

    Objective: to inhibit the harmful chemical gas produced in the fume hood, prevent its leakage, and discharge it out of the laboratory as soon as possible, so as to protect the safety of the laboratory staff. When the regulating door of the fume hood is in any position, the wind speed on the regulating door of the fume hood shall be kept constant. The national standard is 0.4 ~ 0.6 m / s.

    • The fume hood is equipped with displacement sensor, wind speed sensor, personnel induction sensor, VAV air valve and control display.
    • The room is controlled by the residual air volume (exhaust air volume + residual air volume - supply air volume = constant value), that is, the supply air adopts CAV or VAV, and the exhaust air is controlled by VAV according to the room pressure.
