The U-type ground heat exchanger is a significant component of the ground source heat pump (GSHP) system, transferring heat from the soil for the air conditioning requirements. Heat accumulation becomes a common problem for the practical application of such systems in southern China. Moreover, the buried pipes containing heat exchangers are constructed in a group form, making the heat accumulation...
The multi-zone model is widely used to predict airflow and contaminant transport in large buildings under natural or mechanical ventilation. Selecting appropriate mixing factors and particle deposition velocities for the multi-zone model can compensate for the errors resulting from the model’s well-mixing assumption. However, different room types, air change rates and ventilation modes can result...
