A differential pressure gradient control method, device, equipment and storage medium for a multi-room laboratory

Abstract

The present application relates to the technical field of building ventilation and environmental control, and provides a differential pressure gradient control method, device, equipment and storage medium for a multi-room laboratory, wherein current differential pressure data and interference source state signals of the room are acquired, and interference source state signals of other rooms are received through a communication connection; feedback air volume adjustment instructions are generated based on the differential pressure data through a feedback algorithm; interference source state signals of the room and / or other rooms are input into a feedforward model to generate feedforward air volume adjustment instructions; feedback and feedforward instructions are superimposed to generate total air volume adjustment instructions to adjust air supply or exhaust volume; and the interference source state signals of the room are sent to other rooms when an interference event is detected. Through feedforward-feedback composite control and inter-room collaborative early warning, the present application realizes rapid response, global stability and flexible deployment of the differential pressure gradient.
