<P>PROBLEM TO BE SOLVED: To provide an apparatus for presenting removable silencing elements for supporting a design to remove any unnecessary silencing element for cost reduction by presenting removable silencing elements if the noise value of a room to be air-conditioned meets a noise regulation value. <P>SOLUTION: When the composite noise value of rooms to be air-conditioned and/or ventilated in each air-conditioning/ventilating duct system in an initial plan inputted do not exceed the noise regulation value, the apparatus for presenting removable silencing elements performs calculations for comparison of adjacent elements in the air-conditioning/ventilating duct system of the highest sound level, from the downstream side to the upstream side of a duct, and searches the system toward a downstream element when the power level of the downstream element is greater, and toward the part of the duct located upstream of the downstream element. For the air-conditioning /ventilating duct system where the silencing element between the downstream element and another element upstream of an element whose power level is higher than that of the downstream element, cases where the composite noise value of the rooms to be air-conditioned and/or ventilated does not exceed the noise regulation value are detected. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
