Title:
WATER SUPPLY CONTROL SYSTEM AND WATER SUPPLY CONTROL METHOD
Document Type and Number:
Japanese Patent JP2009030821
Kind Code:
A
Abstract:

To perform end differential pressure control for performing pressure control by an invertor pump on the basis of end differential pressure even if a pipe end cannot be specified.

This water supply control system comprises differential pressure measuring means mounted to valves 6-1 to 6-3 disposed at inlets of a plurality of load apparatuses 5-1 to 5-3 and measuring differential pressure between supply water at the inlet of each of the plurality of load apparatuses 5-1 to 5-3 and return water at the outlet of each of the plurality of load apparatuses 5-1 to 5-3, and the water supply control device 12 comparing the plurality of differential pressure measured by the differential pressure measuring means, specifying the end differential pressure of the pipe end, and controlling rotational speeds of pumps 9-1, 9-2 and an opening of a bypass valve 10 based on the end differentioal pressure.
