This paper compares air-cooled and water-cooled precision air conditioners used in computer rooms from six aspects: energy-saving measures that can be adopted, system safety, system investment, system operation and maintenance, load change adaptability, and system energy efficiency. Results showed that the air-cooled precision air-conditioning system has excellent performance in terms of safety, initial investment, operation and maintenance requirements, adaptability to load changes, and energy efficiency compared to water-cooled precision air-conditioning systems; air-cooled precision air conditioners cannot adopt integrated energy efficiency measures for cogeneration. This paper offers a reference for the selection of precision air conditioners for data centers.
