The common machine room adopts a compressor refrigerating system to run all the year round to prepare low-temperature chilled water or low-temperature refrigerant to cool air. Besides, a fan is required to be configured to force air in the machine room to flow and dissipate heat. According to statistics, in the mode, the energy consumption of the air conditioner accounts for 35% -45% of the total energy consumption of the machine room. Some air conditioning systems utilize outdoor cold air and cold water systems for natural cooling, the cooling mode mainly achieves the purpose of energy saving by reducing the running time of the compressor, but the compressor is still required for refrigeration when the temperature is high in summer, the energy saving effect can reach about 50% when the air conditioning is adopted for natural cooling, and the power consumption is still large; in addition, the cooling by adopting an air conditioning mode has the disadvantages of complex air conditioning equipment, need of various mechanical devices and rotating equipment, large initial investment and troublesome maintenance.
In addition, with the development of information technology, the operation speed of the server is increased, the heat dissipation capacity of the server and the heat dissipation density of a machine room are increased, and the limitation of a mode of heat dissipation by means of a large amount of air is more obvious. It is anticipated that in the near future, both from the energy saving and heat dissipation perspective, air cooling approaches have been difficult to meet the heat dissipation requirements of servers.
