Research On Energy Saving Effect Evaluation Of Data Center Refrigeration System

Data center design in recent years,rapid development,a variety of technical updates after another,in the security and stability has basically reached the expectations of the premise,the design concept gradually transferred to energy conservation.In this paper,mainly for large-scale data center energy-saving planning analysis and around the air-conditioning cold source system design for some energy-saving aspects of exploration.Discrimination indicators use the most widely used PUE algorithm in the world,because the commonly used refrigeration forms contain a variety of,such as air-cooled,water-cooled,ice storage,and each in a particular environment with energy-saving or economic advantages.According to the progress of the construction of the data center,the load will be larger stage,so only a single way of cooling is not scientific nor economical.Using a variety of cooling methods coexist,and by adjusting the most suitable for the current load of the cooling method to achieve maximum energy savings has become the majority of the designer design concept of the direction of development.In this thesis,three data center room as an example of a variety of refrigeration methods for PUE value comparison and economic analysis and based on the test results to determine a cooling method in the current load under the premise of the best choice is not the best choice Study on the Direction of Energy Saving Optimization.
