In order to develop a more accurate photovoltaic–thermal collector and ground source heat pump integrated simulation model, it is necessary to consider the operation condition assumed in real situations, such as partial load of system, energy use situation, or energy production condition. Furthermore, the integrated simulation model should be verified by measurement data based on real-scale experiment. Therefore, in this study, we constructed a demonstration plant considering the real application for a residential house, and installed a monitoring system that could measure detailed operation situations, such as weather conditions, heat source temperatures, and individual system performance. The integrated simulation model was composed of a Photovoltaic–thermal collector model, a ground heat exchanger model, a heat pump model, a building load model, and a controller model. The error rate between the monitoring result and the integrated simulation model was determined. This was used to verify the prediction accuracy of the integrated simulation model. The coefficient of variation of root mean square error (CV(RMSE)) for the heat pump coefficient of performance (COP) and system coefficient of performance were calculated as 19.2% and 14.8%, respectively. In addition, the error rates of the PVT collector and the heat pump relative to the daily heat exchange rate (HER) were calculated to be less than 30%, respectively, while the error rate of the integrated simulation model satisfied ASHRAE Guideline 14-2014. Moreover, the long-term performance of the system was analyzed through the integrated simulation model considering the weather condition of Seoul. The annual COP of the system was calculated to be 4.03.

光伏光热与地源热泵三联供系统开发的实验与模拟比较


为了开发更准确的光伏集热器和地源热泵集成仿真模型，需要考虑实际情况下假设的运行条件，例如系统的部分负荷、能源使用情况或能源生产情况。此外，综合仿真模型应通过基于实际规模实验的测量数据进行验证。因此，在本研究中，我们考虑到住宅的实际应用，建造了一个示范工厂，并安装了一个监控系统，可以测量详细的运行情况，如天气状况、热源温度和单个系统性能。综合仿真模型由光伏集热器模型、地热交换器模型、热泵模型、建筑负荷模型和控制器模型组成。确定了监测结果与综合仿真模型之间的误差率。这用于验证集成仿真模型的预测准确性。经计算，热泵性能系数（COP）和系统性能系数的均方根误差（CV（RMSE））变异系数分别为19.2%和14.8%。此外，经计算PVT集热器和热泵相对于日热交换率（HER）的误差率分别小于30%，而综合仿真模型的误差率满足ASHRAE Guideline 14-2014 。此外，考虑首尔的天气条件，通过综合仿真模型分析了系统的长期性能。经计算该系统的年COP为4.03。
