一种基于TRNSYS的闭式热源塔冬季工况模拟计算方法

目前所给出的闭式热源塔计算方法主要是针对闭式热源塔的一些特定工况和条件提出的,存在着一定的局限性。本文利用FORTRAN编程语言在TRNSYS模拟平台上建立了闭式热源塔的计算模型,给出了相关结构参数及换热系数的求解过程,通过与其他学者的实测数据及计算数据进行对比,验证该模型的正确性。验证结果表明,干工况、干-湿混合工况以及防霜工况的理论计算结果与实测结果均误差较小,表明本文所建立的计算模型准确度较高,能够满足闭式热源塔全年模拟分析的要求。

A simulating method of closed heat source tower in winter based on TRNSYS

At present,the calculation method of closed source tower is mainly put forward for some specific working conditions and conditions of closed source tower,which has some limitations. In this paper,FORTRAN programming language was used to establish the calculation model of closed heat source tower on TRNSYS simulation platform,and the solution process of related structural parameters and heat transfer coefficient was given. The correctness of the model was verified by comparing with the measured data and calculated data of other scholars. The verification results show that the theoretical calculation results in dry conditions,dry-wet mixing conditions and frost prevention conditions have small errors with the actual test results,indicating that the calculation model established in this paper has high accuracy and can meet the requirements of year-round simulation analysis of closed heat source tower.
