Abstract

The present disclosure relates to the field of refrigeration system technology, and discloses a refrigeration system for a data center. The data center includes a liquid-cooled server, and the refrigeration system includes a liquid cooling system and an air cooling system. The liquid cooling system includes a compressor, a first cooler, and a plate heat exchanger constituting a refrigerant circulation circuit. The plate heat exchanger includes a first branch and a second branch, where the first branch is configured to circulate a refrigerant, the second branch is configured to circulate a coolant, and the second branch is communicated with a liquid cooling plate of the liquid-cooled server. The air cooling system includes a second cooler, a refrigerant drive apparatus, a throttling apparatus, and an evaporator constituting another refrigerant circulation circuit. An inlet of the second cooler is communicated with an outlet of the first branch of the plate heat exchanger.
