摘 要
電腦模擬的技術被應用於許多不同的領域,本論文主要目的為建立一套空調模擬機,以供利用於訓練操作員與評估空調系統,並建立一完整之框架以利後續研究之延伸。
文中先以熱傳與熱力學之基礎建立空調系統中各元件的數學模型,透過物件導向的概念將元件模型實體化,再利用模組化的概念將元件組合成各式系統以進行模擬。 使用物件導向概念建構模擬機系統的目的有二,一是讓模擬機各元件的擴充更加容易,有利於建立一完整之元件庫,其次為統一各系統之模擬方式,讓模擬機更具一般性。
本研究的模擬程式分別與兩組實驗作比對,其模擬結果皆在容許之誤差範圍內,驗證了此系統在使用上的可靠性, 可作為開發更完整功能模擬機之參考依據。
Simulator of Air-Conditioning Systems
Yih, Chen Lun
Abstract
Technology of computer simulation is widely used in many kinds of areas. The purpose of this research is to establish a simulator of air-conditioning systems for operator training and design verification. It also builds a complete structure for further research.
In the text, we build the mathematical models of the elements in air-conditioning systems first, and we realize the models by the concept of “Object-Oriented Analysis” (OOA). At last, we combine the element models and build all kinds of air-conditioning system models by the concept of modulization. There are two purposes of using the concept of OOA. First, it is easier to extend the element models exists, so we can build the complete air-conditioning element model database. It also makes the method of simulation more general.
We compare the simulation results based on this research with two sets of experiment data. The validity of the numerical results is confirmed. This text could be referenced for the research of a more functional air-conditioning simulator.
