Title:
FLUID FLOW SYSTEM, FLOW RATE CONTROL METHOD, CONTROL DEVICE, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/029531
Kind Code:
A1
Abstract:
The system according to one embodiment is provided with a fluid flow device 20 that includes a pump 22 and causes a fluid to flow by the rotation of the pump, and a control device 30 that controls the fluid flow device 20. Then, when a target flow rate for the fluid has been changed, the control device 30 derives a rotational speed after change on the basis of the target flow rate and: the flow rate of the fluid and the rotational speed of the pump 22 at the time of changing the target flow rate; or the flow rate of the fluid and the rotational speed of the pump 22 during a predetermined period before changing the target flow rate. The control device 30 then changes the rotational speed of the pump 22 toward the rotational speed after change.
