The invention relates to the technical field of laboratory ventilating
control equipment, in particular to a laboratory ventilating management
control system. The laboratory ventilating management
control system comprises a ventilating management controller, a first POWER, a
differential pressure sensor, a temperature sensor, a plurality of ventilation hoods, a PC
communication interface, a ventilating
system starting device, an air supply air valve control / Venturi valve control device, an auxiliary exhausting air valve control / Venturi valve control device, a switching value air valve, an illuminating control device and a touch screen. The constant
differential pressure is utilized, the
differential pressure in a room is detected and compared with a preset value, and the size of a valve isadjusted (the
air volume of a Venturi valve is adjusted), for example, when the preset value is larger than an actual value, under the condition of meeting the
air exchange frequency, auxiliary exhausted air is increased, or supplied air is reduced; when the preset value is smaller than the actual value, under the condition of meeting the
air exchange frequency, the auxiliary exhausted air is reduced, and the supplied air is increased; and
intelligent control management is achieved, operation is easy, and use is convenient.
