Abstract
The ventilation mode affects the cooling efficiency of the air conditioners significantly in marine data centers. Three different ventilation modes, namely, underfloor ventilation, overhead ventilation, side ventilation, are numerically investigated for a typical marine data center. Four independent parameters, including temperature, velocity, air age, and uniformity index, are applied to evaluate the performances of the three ventilation modes. Further, the analytic hierarchy process (AHP) entropy weight model is established and further analysis is conducted to find the optimal ventilation mode of the marine data center. The results indicate that the underfloor ventilation mode has the best performance in the airflow patterns and temperature distribution evaluation projects, with the highest scores of 91.84 and 90.60. If low energy consumption is required, it is recommended to select the overhead ventilation mode with a maximum score of 93.50. The current evaluation results agree fairly well with the three dimensional simulation results, which further proves that the AHP entropy weight method is reasonable and has a high adaptability for the evaluation of air conditioning ventilation modes.
Highlights
In recent decades, numerous data centers have been built throughout the world due to the need for the development of integrated information
This paper aims to establish a comprehensive evaluation model for the ventilation mode based on the analytic hierarchy process (AHP) entropy weight method
The AHP entropy weight method used in this study provides a theoretical reference for the selection and optimization of air conditioning ventilation modes in the future
Summary
Numerous data centers have been built throughout the world due to the need for the development of integrated information. It has been reported that power consumption in data centers accounts for approximately 1.3% of the total worldwide electricity consumption in 2010 [1,2]. With the increase of the servers’ heat load, a corresponding higher heat dissipation is required in data centers as the electrical power supplied to the servers is in essence converted to heat [1]. Air cooling is still the predominant method for data centers. The indoor air flow distribution has a major impact on the thermal environment in marine data centers and can greatly affect air cooling energy efficiency [3,4]
