The pressure loss of the damper (resistance coefficient Kx × air volume Q2 2 ) is subtracted from the pressure P2 of No. 2 . Until the pressure P3 of the node N3 reaches a predetermined value (for example, a design value), an iterative calculation for changing the resistance coefficient Kx (variable) of the damper is performed to obtain the opening degree θ2. Note that the relationship between the resistance coefficient Kx of the damper and the opening θ2 is represented by an approximate expression prepared in advance, and the resistance coefficient Kx is converted into the opening θ2 by the approximate expression.

That is, data necessary for creating a calculation sheet such as a node name of a duct system of a nuclear power plant, a resistance coefficient between nodes, an air volume between nodes, a pressure loss between nodes, a pressure calculation formula, etc. are input from the input unit 30 of the arithmetic unit. (Step S

Therefore, first, the range of the pressure loss of the damper is input as a constraint condition from the input unit 30 based on the design value such as the pressure level of each area (the pressure value to be obtained at a required node) (step S5). Next, after selecting a damper to be calculated (step S6), the resistance coefficient of the damper is changed (step S7), and it is determined whether or not the constraint condition is satisfied (step S8). If the above constraint condition is satisfied, the process moves to the calculation of the damper downstream of the constraint (step S9), and the same processing is repeated.

の抵抗係数等を測定値をもとに修正後、再度計算する。Next, a procedure for adjusting the opening degree of the damper using the present support software will be described. It is assumed that the pressure and air volume at the duct position corresponding to a certain node are measured and deviate from a predetermined value. The opening degree of the damper near the node is adjusted to the value calculated by the support software. As a result, it is confirmed that the calculated value matches the measured value. If the difference between the two cannot be ignored, the duct system resistance coefficient and the like set under the calculation conditions are corrected based on the measured values, and then the calculation is performed again.

Actually, the pressure and the air flow are measured at the position of the node which is estimated to be affected, and if it is within the allowable range, the process moves to the next adjustment point. If the permissible range is exceeded, the openings of the related dampers are recalculated, and the openings of the dampers in which the pressures and air volumes of all the nodes of the system are within the permissible range are obtained.
