Abstract
Refrigeration system is an important part of high-efficiency data centers. Air distribution optimization is an important means of energy saving in the air conditioning system. In this paper, aiming at the shortcomings of the existing evaluation indexes of air distribution in data center, the Entransy loss method based on the thermodynamics principle is applied to the evaluation of air distribution in the data center. Taking a standardized data center as the research object, CFD is used to simulate the four working conditions of its cold and hot channels. The results show that the thermal Entransy loss can effectively evaluate the cooling capacity utilization of different airflow organization forms, which provides a theoretical basis for optimizing the airflow organization and evaluating the heat transfer performance of the entire engine room. The results show that the thermal Entransy loss can effectively evaluate the cooling capacity utilization of different airflow organization forms, which provides a theoretical basis for optimizing the airflow organization and evaluating the heat transfer performance of the entire engine room.
