  • Temperature control device
    Patent number: 6659361
    Abstract: The controller 70 of the brine supply device 10 performs the PID calculation of the manipulated variable MV of the valve 14, calculates the compensated manipulated variable MV′ by compensating the manipulated value MV, and controls the operation of the valve 14 based on the compensated manipulated variable MV′. The variation &Dgr;MV of the manipulated variable MV becomes proportional to the variation &Dgr;PV of the brine supply temperature Pt1 as the operation of the valve 14 is controlled with the compensated manipulated variable MV′. This makes it possible to control temperature with a high accuracy using only one set of PID constants.
    Type: Grant
    Filed: February 27, 2003
    Date of Patent: December 9, 2003
    Assignees: Nishiyama Corporation, Aquatech Co., Ltd.
