REFRIGERATION SYSTEM AND REFRIGERATION METHOD FOR DATA CENTER

机译:数据中心的制冷系统及制冷方法

摘要

The present disclosure provides a refrigeration system and refrigeration method for a data center. The refrigeration system comprises: a first heat exchanger disposed on a back plate of an indoor cabinet of the data center, and a phase-change heat-exchange cooling tower disposed outdoor of the data center; the first heat exchanger and the phase-change heat-exchange cooling tower are communicated by a secondary refrigerant delivery pipeline; the secondary refrigerant delivery pipeline obtains a secondary refrigerant in liquid-state from the phase-change heat-exchange cooling tower and delivers the secondary refrigerant to the first heat exchanger, the secondary refrigerant absorbs heat on the first heat exchanger and becomes gas to refrigerate for the indoor of the data center where the first heat exchanger lies; the secondary refrigerant delivery pipeline further delivers the secondary refrigerant in gas-state to the phase-change heat-exchange cooling tower, and the phase-change heat-exchange cooling tower transfers heat carried in the secondary refrigerant into air and condenses the secondary refrigerant to a liquid again; the secondary refrigerant employs a phase-change heat-exchange working medium. The refrigeration system of the data center according to the present disclosure can easily achieve 100% refrigerator-free water-free highly-efficient and energy-saving refrigeration, has a simple structure and can reduce the maintenance costs.
