摘要

摘要提出了一种新的基于物理的模块化变制冷剂流量(VRF)热泵模型,旨在实现多年模拟。该模型允许模拟任意数量的室内机(IU)、室外机(OU)和压缩机。提出了一种基于制造商数据的参数估计方法和控制策略。该模型是根据从VRF系统收集的数据进行验证的,该系统服务于亚特兰大(美国)前ASHRAE总部大楼的一楼,由22个室内单元,2个室外单元和8个压缩机组成。结果表明,该模型准确预测了2个月制冷期的总能耗,相对误差为1%,归一化平均偏差误差(NMBE)为1.6%,均方根误差变异系数(CVRMSE)为16.7%。关键词:可变制冷剂流量泵模型校准控制器仿真免责声明作为对作者和研究人员的服务,我们提供此版本的接受手稿(AM)。在最终出版版本记录(VoR)之前,将对该手稿进行编辑、排版和审查。在制作和印前,可能会发现可能影响内容的错误,所有适用于期刊的法律免责声明也与这些版本有关。

Variable refrigerant flow heat pump model with estimated parameters and emulated controller based on manufacturer data
AbstractA new physics-based and modular variable refrigerant flow (VRF) heat pump model aimed towards multi-year simulations is presented. The model allows the simulation of any number of indoor units (IU), outdoor units (OU) and compressors. A parameter-estimation procedure and a control strategy both using available manufacturer data is proposed. The model is validated against data collected from a VRF system that services the first floor of the former ASHRAE Headquarters Building in Atlanta (USA), comprised of 22 indoor units, 2 outdoor units and 8 compressors. Results show that the model accurately predicts the total energy consumption over a 2-month cooling period, with a relative error, normalized mean bias error (NMBE), and coefficient of variation of the root mean square error (CVRMSE) of 1%, 1.6%, and 16.7%, respectively.Keywords: variable refrigerant flowheat pumpmodel calibrationcontroller emulationDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM). Copyediting, typesetting, and review of the resulting proofs will be undertaken on this manuscript before final publication of the Version of Record (VoR). During production and pre-press, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal relate to these versions also.
