Research on pre-cooling energy saving of data center

For the energy saving scheme using outdoor natural cold source, puts forward the concept of data center pre-cooling and the assessment approach to achieve energy saving effect of pre-cooling. According to an actual project, designs the pre-cooling computer room air conditioning (CRAC) unit, and based on the meteorological data in Shanghai area, gives theoretical analysis for energy saving. Points out the development direction of pre-cooling energy saving technology in data center.
