ASHRAE的TC 6.9要求对RP-459（冰蓄冷系统计算机模拟的组件模型）的管道和冰蓄冷罐组件进行评估。该项目为RP-733，旨在进行评估。这项工作包括彻底重新检查这些算法，并将使用它们的计算机模拟结果与实验数据进行比较。结论是，RP-459算法为循环的制冰部分提供了合理的结果，但没有很好地跟踪融化。 主要困难在于，融化算法基于冰均匀地从管道上融化的假设。实验结果表明，情况并非如此；因此，这些算法不能模拟实际的系统性能。此外，还将结冰算法与使用更快、更简单算法的模型进行了比较。这一比较表明，RP-459冰建模型与简单模型相比，没有提供更好的数据匹配。因此，对更简单的算法和建模方法进行了描述，并建议在未来的仿真中考虑该方法。 关键词:1995年，计算，算法，精度，比较，融化，储能，冰，管道，部件，冰储能，储罐，部件，性能，热流，实验，测试引用:研讨会，ASHRAE Trans。1995年，第101卷，第2部分

ASHRAE's TC 6.9 requested an evaluation of the ice-on-pipe and ice storage tank components of RP-459, Component Models for Computer Simulation of Ice Storage Systems. This project, RP-733, was undertaken to perform that evaluation. The work consisted of a thorough re-examination of those algorithms and a comparison of results of a computer simulation employing them with experimental data. The conclusion is that the RP-459 algorithms provide reasonable results for the ice-building portion of the cycle but do not track the melting well. The primary difficulty is that the melting algorithms are based on the assumption that the ice melts off the pipes uniformly. The experimental results indicate that this is not the case; therefore, the algorithms do not model actual system performance. The ice-build algorithms were also compared with a model using faster and less complex algorithms. This comparison indicated that the RP-459 ice-build model does not provide a better match of the data than does the simpler model. Consequently, a description of the simpler algorithm and modelling approach is presented with the recommendation that it be considered for future simulations.KEYWORDS: year 1995, calculating, algorithms, accuracy, comparing, melting, energy storage, ice, pipes, components, ice storage, tanks, components, performance, heat-flow, experiment, testing
