由计算流体力学(CFD)导出的室内气候贡献率(CRI)被用来估计热因素对房间内任何位置的个体贡献。CRI指标反映了温度场的结构，使CFD结果能够更有效地应用于分析和设计。本研究首先介绍了CRI的概念和计算方法。作为CRI的应用实例，提出了一种基于CRI的房间内任意点温度预测方法，该方法具有少量温度传感器。通过将预测结果与CFD和辐射耦合模拟结果进行比较，验证了该方法的准确性。
The contribution ratio of indoor climate (CRI) derived from computational fluid dynamics (CFD) was developed to estimate the individual contribution of heat factors to any location inside a room. The CRI index indicates the structure of the temperature field and allows the CFD results to be applied to analysis and design, with more efficient application. In this study, the concept and calculation method for CRI is introduced first. As an example of the application of CRI, a method for predicting temperatures at any point in a room with a small number of temperature sensors based on CRI is developed. The accuracy of the method is examined by comparing the prediction with a coupled simulation of CFD and radiation.
