Influence of underfloor air distribution modes on thermal environment performance of data center

Simulates the airflow streamlines and temperature fields of four typical data center underfloor air distribution modes of cold/hot aisle airflow open-ended mode (C/HAOS), hot aisle containment mode (HACS), cold aisle under rack mode (CURS), and cold aisle containment mode (CACS). According to ASHRAE TC 9.9, evaluates the thermal environment performance. The results show that four typical modes have their own advantages and disadvantages, and should be applied according to the requirements in the implementation. Compares the measured data and simulation results, and adopts supply heat index (SHI) and return heat index (RHI) to evaluate the thermal stability and energy efficiency of the data center.
