TRNSYS 動態模擬軟體

​​​TRNSYS_logo.jpg

TRNSYS 是用於模擬瞬態系統的行為的軟件環境,極為靈活且介面非常圖形化。絕大多數模擬都集中在評估熱能和電能系統的性能,TRNSYS 可以很好地用於其它動態系統,如交通流,或生物過程建模。 

TRNSYS 是由兩部分組成。第一是發動機 (kernel),讀取和處理輸入文件,解決系統、確定收斂,並且重複系統變量,還提供確定熱物理性質,反轉矩陣,進行線性回歸,插值和外部數據文件的實用程序。TRNSYS 的第二部分是一個組件的一個廣泛的文庫,其中每一個模型的系統的一個組成部分的性能。標準庫中包含了約 150 款,從泵多區建築、風力渦輪機電解槽、氣象數據處理器經濟學例程和基本 HVAC 設備和尖端的新興技術。

TRNSYS (pronounced 'tran-sis') is an extremely flexible graphically based software environment used to simulate the behavior of transient systems. While the vast majority of simulations are focused on assessing the performance of thermal and electrical energy systems, TRNSYS can equally well be used to model other dynamic systems such as traffic flow, or biological processes. 

TRNSYS is made up of two parts. The first is an engine (called the kernel) that reads and processes the input file, iteratively solves the system, determines convergence, and plots system variables. The kernel also provides utilities that (among other things) determine thermophysical properties, invert matrices, perform linear regressions, and interpolate external data files. The second part of TRNSYS is an extensive library of components, each of which models the performance of one part of the system. The standard library includes approximately 150 models ranging from pumps to multizone buildings, wind turbines to electrolyzers, weather data processors to economics routines, and basic HVAC equipment to cutting edge emerging technologies. Models are constructed in such a way that users can modify existing components or write their own, extending the capabilities of the environment.

After 35 years of commercial availability, TRNSYS continues to be a flexible, component-based software package that accommodates the ever-changing needs of both researchers and practitioners in the energy simulation community.
