Purpose: Internet data usage has increased due to the growth of the OTT (Over The Top) service market and the 5G Network. Interests and needs on a data center (a facility storing, processing, and managing the data) have rapidly increased in the past few years. That means the increased demand is driving the boom in data center construction and it leads to increased energy consumed by the data center. The data center consumes energy mainly for IT equipment and cooling systems to remove the heat generated by the IT equipment. The cooling energy consumption accounts for approximately 40% of the total energy consumption in the data center. To achieve cooling energy savings in a data center, understanding heat generated from the data center operation is essential. However, there is a lack of energy model to evaluate causes and effects between IT heat loads and cooling system thermal performance.
Therefore, this study aims to develop an energy simulation model that evaluates thermal characteristics of the data center and analyzes the cooling energy. Method: This study developed and verified the IT equipment operation schedule for simulation using the measurement data of the ‘A’ research facility located in Daejeon, South Korea. In addition, the air flow was analyzed by varying the heat load values for each IT space separately. Result: This study validated the IT equipment and cooling energy consumption of the developed data center model using ASHRAE Guideline 14, and the model met the specified criteria.
