本研究基於國內船舶空調系統設計之概念，即以整體性的機艙佈置設計規劃為前提，針對風管設計流程之簡化與自動化做探討，以期能達到降低設計工時並節省材料成本的最適化通風設計。本研究首先於PDMS完全三維設計工作平台上，製作通風系統之CAD立體初步模型以取代過去使用二維圖像敘述之風管系統，以PML語言發展整個通風管路之機能設計流程，包含最適風管路徑計算、管路路徑資料編輯，配合等摩擦法決定之通風管徑建構一組基礎管路模型，接著依船體機艙空間結構特性與風管路徑佈置架構，尋找適合通風管路依附之船體結構物件(Pillar、Frame、Gird)，由程式調整修改管路模型進而發展通風系統之最適化設計。

本研究的優點是機艙整體風管設計皆使用PDMS 3D環境中規劃，使計算與設計皆在同一工作平台上進行，風管的生產資訊、圖形資料與施工圖皆使用同一資料庫，可直接自PDMS取得，以達到設計資訊之取得的方便性與正確性。融合船體結構以簡化機艙通風管路路徑佈置的最適化設計概念，即盡量依附於艙體結構的骨架來放置通風管路，使機艙空間有效利用率提升，增加機艙空間的完整性，並精簡風管支架與風管元件的材料成本，同時達到增加船體結構強度的好處。

Basing on the design conception of HV AC of shipbuilding in Taiwan, the simplification and automation of design work flow are mainly described in this paper on the basis of the entirety design plan of engine room arrangement, in order to reduce the designers’working hours and lower the material cost. First of all, make the 3D ventilation system key model to replace the 2D graph description used before on the PDMS entirely 3D design platform and develop the functional design

system of HV AC including the optimum routing computing and information compilation with the PML language, and construct a set of foundational vent model on account of the diameter-determining approach of Equal Friction Method, then arrange all the vents according to the characteristic of engine room structure. Later on, seek for the component like Pillar, Frame and Gird where the ducts are suitable to attach and revise the duct model with programs to develop an optimum design for HV AC.

The advantage of this research is to map out the entirely engine room duct design in the PDMS 3D environment which makes the computation and design process on a same platform. The production information, graph data and construction drawing of ducts are all stored in the same database which can be accessed directly from PDMS that has the higher convenience and correctness of information acquiring. The optimized conception of merging the ducts into the hull structure to simplify the duct routing arrangement, in other words, we attach the ducts to the architecture of hull structure which raises the effective utility rate of the engine room and increase the completeness of the engine room, furthermore, it even lowers the material cost of supports and components of ducts and strengthens the intensity of hull structure at the same time.

Key words: Engine room arrangement, HV AC, Hull structure
