    实验室通风与舒适性空调系统的通风设计要求不同,主要目的是提供安全、舒适的工作环境,减少人员暴露在危险空气下的可能。通风主要解决的是工作环境对实验人员的身体健康和劳动保护问题。
    The ventilation requirements of laboratory ventilation and comfort air conditioning system are different. The main purpose is to provide a safe and comfortable working environment and reduce the possibility of exposure to dangerous air. Ventilation mainly solves the problem of the physical health and labor protection of the workers in the working environment.
    在现代化实验室设备中有通风柜、中央实验台、边台、药品柜、器皿柜、气瓶柜等,其中通风柜是生化实验室设备中担负着十分重要的功能,是必不可少的设备。因此,选择通风柜是实验室建设中的重要问题,必须引起足够的重视。
    In modern laboratory equipment, there are fume hood, central test stand, side table, medicine cabinet, vessel cabinet, gas bottle cabinet, etc., and ventilation cabinet is a very important function in biochemical laboratory equipment, and is an essential equipment. Therefore, the selection of the ventilator is an important problem in the construction of the laboratory, and it must be paid enough attention.
    1、静压变频控制系统
    1, static pressure frequency control system
    静压变频控制系统是根据管道压差数据针对实验室排风量实时变化及时调整排风机运转频率,降低或增大排风量,进而达到节能、降噪的自动化控制系统。
    The static pressure frequency conversion control system is an automatic control system based on the data of pipeline pressure difference, which can adjust the running frequency of the exhaust fan timely, adjust or decrease the air exhaust volume, and achieve the energy saving and noise reduction.
    2、PLC变频控制系统
    2, PLC variable frequency control system
    PLC变频控制系统,是根据探测通风柜的开关信号,来自动调整风机的运行频率,进而在满足安全的前提下实现节能环保的效果。
    The PLC frequency conversion control system adjusts the running frequency of the fan automatically according to the switch signal of the detecting ventilator, and then achieves the energy saving and environmental protection effect under the premise of satisfying the safety.
    3、VAV变风量控制系统
    3 and VAV VAV control system
    VAV系统可以及时有效调整并精准保持通风柜面风速恒定在安全值上,不论通风柜的玻璃视窗开启高度大小。这是安全节能的典范。
    The VAV system can effectively adjust and maintain accurate face velocity constant in the safety value, whether ventilation cabinet glass windows open height size. This is a model of safety and energy saving.
