Abstract

The invention discloses a thermal-insulation closed cooling system for a data center. The thermal-insulation closed cooling system is characterized in that a thermal-insulation closed evaporative cooling tower, a water-cooling water chilling unit and a data center air conditioning terminal are connected through valves, and control system controls the valves to achieve switching among a water chilling unit cooling mode, a natural cooling mode and a preset cooling mode; in the water chilling unit cooling mode, the water-cooling water chilling unit is used as the cold source to cool the data center air conditioning terminal; in the natural cooling mode, the thermal-insulation closed evaporative cooling tower is used as the cold source to cool the data center air conditioning terminal; in thepreset cooling mode, the thermal-insulation closed evaporative cooling tower and the water-cooling water chilling unit are in series operation, and water discharged from the thermal-insulation closedevaporative cooling tower is further cooled in the evaporator of the water chilling unit and then used to cool the data center air conditioning terminal. The thermal-insulation closed cooling system has the advantages that the preset cooling mode is added to the system, the thermal-insulation closed evaporative cooling tower and the water-cooling water chilling unit are in series operation in thepreset cooling mode, the operation time of the water chilling unit is shortened greatly, and power consumption is lowered greatly.

Description

technical field [0001] The invention relates to the field of industrial cooling, in particular to an adiabatic closed cooling system for data centers and a cooling method thereof. Background technique [0002] With the rapid development of cloud computing and big data, the energy consumption of data centers has become a subject of much concern. Among the energy consumption of the data center, the energy consumption of the air conditioning system reaches 40% to 60%. The data center mainly uses two technical indicators to evaluate the energy consumption and water consumption. The ratio of the total electric energy consumed by electrical equipment to the total electric energy consumed by all IT equipment, water consumption WUE, is the ratio of the water resource consumption of the data center to the annual power consumption of IT equipment in the data center, and the unit is L / kwh. The average value of data center PUE in the global computer room is 2.0, and the average value i...
