Heat Removal Efficiency Based Multi-node Model for Both Stratum Ventilation and Displacement Ventilation
The energy-saving effectiveness of stratum ventilation, as compared to mixing ventilation, is attributed to the non-uniform distribution of vertical air temperature. However, accurately predicting this distribution using a multi-node model presents challenges for engineers due to its dependency on complex airflow patterns and specific ventilation designs. To address this issue, this chapter proposes a practical approach known as the Heat Removal Efficiency (HRE) based multi-node model. By utilizing HRE to represent airflow patterns, this model offers simplicity and versatility, requiring minimal understanding of airflow dynamics. Experimental results demonstrate the superiority of the proposed model, achieving higher accuracy and robustness compared to conventional models. It reduces the mean absolute error in temperature predictions for air nodes and enclosure surfaces of stratum ventilation by 0.1 °C and 0.08 °C, respectively. The improved convenience, generality, flexibility, accuracy, and robustness of the proposed model make it a practical solution for implementing energy-efficient stratum ventilation.
