  • Patent number: 7383693
    Abstract: A cooling device includes a branch line with one end thereof communicating with a supplying line, and the other end communicating with a recovery line, wherein a part of the refrigerant supplied to the supplying line by a pump, flows as a branch; a heater installed in the middle of the branch line, for heating the refrigerant up to temperature higher than that for freezing moisture dissolving in the refrigerant; and a moisture adsorption filter installed in the middle of the branch line, through which the refrigerant heated by the heater passes, for adsorbing moisture mixed in the refrigerant.

  • 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.
