Abstract

The invention relates to the technical field of ventilation equipment engineering, in particular to an intelligent distributed negative pressure ventilation control system. Fresh air distributed in all areas or rooms comes from a shared fresh air fan; the distributed fresh air of the independent areas or rooms is controlled by a distributed terminal controller according to the requirement for a negative pressure difference to control the opening degree of an inlet of a fresh air valve; the fresh air feeding amount is adjusted; exhausted air distributed in all areas or rooms is exhausted to a shared exhaust fan; the exhaust fan is controlled and adjusted through an exhaust unit to meet the requirement for the pressure of an exhaust pipe to conduct variable-frequency exhaust; an intelligent master controller conducts centralized management and control, data acquisition and analysis, working mode adjustment and operation parameter optimization setting on a fresh air unit control cabinet, an exhaust unit control cabinet and distributed terminal controllers in all the control ranges through communication; and the intelligent distributed negative pressure ventilation control system has the advantages that distributed independent control, centralized management, data analysis and calculation strategies are achieved, independent control and overall control stability of each independent area are both considered, and the negative pressure control effect of each area is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment engineering, in particular to an intelligent distributed negative pressure ventilation control system. Background technique [0002] General hospital wards, laboratories, and important areas of pharmaceutical workshops are equipped with ventilation systems, and fresh air conditioners are generally used for constant temperature ventilation. With the outbreak of the epidemic in recent years and the possibility of responding to emergencies in the future, the requirements for ventilation at home and abroad have been raised to At a new height, in addition to constant temperature, the ventilation in the isolated area needs to meet the negative pressure control requirements, and at the same time, it must take into account the energy-saving operation in normal times, and the special working conditions must be able to quickly switch to meet the rapid ventilation under special circumstances and...
