Abstract

The invention discloses a data center energy-saving air conditioning system and an adjusting method. The air conditioning system comprises a centrifugal water chilling unit, a cooling tower, a plate heat exchanger, an air conditioning terminal, a cold water pump, a cooling water pump and valves V1-V8. The centrifugal water chilling unit comprises a condenser and an evaporator. The data center energy-saving air conditioning system has multiple working modes, and a natural cold source is used for indirectly providing the cooling capacity for the air conditioning terminal through the cooling tower in winter and transition seasons. A cooling tower free cold supply mode is adopted in winter, a cooling tower precooling mode is adopted in the transition seasons, and a conventional refrigeration mode is adopted in summer. The cooling efficiency of a data center machine room is improved, and PUE is reduced.

Description

technical field [0001] The invention relates to the field of data centers, in particular to an energy-saving air-conditioning system for a data center. Background technique [0002] With the rapid development of the electronic information industry, the development of data centers has also entered a new stage. According to statistics, data center air-conditioning accounts for about 40% of the entire data center's energy consumption. The more air conditioners are used, the more power they consume, which directly leads to the crisis of power cuts in summer and the problem of a large amount of energy consumption. In this case, free cooling technology refers to the use of natural free cold sources for cooling in whole or in part to reduce the energy consumed by compressors or freezers. The free cold source commonly used at present is mainly the outdoor air in winter or spring and autumn. Therefore, if possible, the location of the data center should be in an area with relative...
