Description

technical field [0001] The present invention relates to the cooling technology of data centers or supercomputing centers, in particular to a cooling device integrating natural cooling, magnetic levitation centrifugal oil-free refrigeration compressor and evaporation and condensation technology, in particular to a cooling device with refrigerant as cooling capacity ( Heat) carrier, high working efficiency, low energy consumption and high safety evaporative cooling compression condensing device with natural cooling. Background technique [0002] In the network computing center in the era of big data, power consumption is the most important operating cost. Among them, the cooling system occupies the most important part of the operating energy consumption of the data center except for the energy consumption of IT equipment. Therefore, a high-efficiency cooling system largely determines whether a data center can meet the standards of an energy-saving and environmentally friendly ...

Problems solved by technology

The heat transfer temperature difference necessary for the two heat exchanges makes the maglev compressor refrigeration system need to operate at a relatively low evaporation temperature. From the perspective of refrigeration thermodynamic cycle, the lower the evaporation temperature, the lower the efficiency of the refrigeration cycle. Therefore, adopt The way chilled water transports cold (heat) affects the working efficiency of the magnetic levitation compressor refrigeration unit;

[0006] (2) Since the cooling capacity (heat) is transferred through the circulation of chilled water, it needs to consume the power of the circulating water pump

If a water-cooled maglev chiller is used, it will consume additional power of the cooling water pump and cooling tower;

[0007] (3) For water-cooled magnetic levitation chillers, cooling water systems such as cooling towers, cooling water pumps, and cooling water circulation pipelines are required, which is complex and increases investment;

[0008] (4) For the water-cooled magnetic levitation chiller, it is difficult to realize the combination of natural cooling function in one unit, and the natural cooling function can only be realized outside the unit through other equipment and systems, resulting in complex system and engineering volume increase;

[0009] (5) Chilled water enters the computer room of the data center, and the leakage of chilled water will bring great risks to the data center
