WATER SUPPLY CONTROL SYSTEM AND WATER SUPPLY CONTROL METHOD

摘要

A water supply control system and a water supply control method are provided to save energy by reducing the energy consumed in the pump head using the differential pressure control method. A water supply control system(12) comprises a water supply pressure receiver(120) receiving the value of the water supply pressure which the pressure sensor measures; a differential pressure receiver(121) receiving the value of the differential pressure which the differential pressure sensor of valve measures through the load apparatus for equipment control; a setting unit(122) setting up the end differential pressure set value with the operation input of user; a differential pressure specific part(123) which compares the differential pressure which the differential pressure receiver receives and specified the end differential pressure; an operation unit(124) computing the inverter number of rotation of the second pump and open degree of the bypass valve; a pump control part(125) controlling the number of rotation of the second pump based on the operation result of the operation unit through inverter; and a bypass valve controller(126) controlling the open degree of the bypass valve based on the operation result of the operation unit.
