Air-conditioning refrigeration method and air-conditioning refrigeration system of data center as well as data center

Abstract

The invention discloses an air-conditioning refrigeration method and air-conditioning refrigeration system of a data center as well as the data center. The refrigeration method comprises the step of switching among the following refrigeration modes: when the data center operates in summer, spring and summer transition season and summer and autumn transition season, cooling water cooled by a cooling tower takes away heat of a condenser of a water cooling unit; freezing water of multiple water cooling units which are connected in parallel or in series is fed into an air-conditioning unit and exchanges heat with the air; and when the data center operates in winter, refrigerant water prepared after the freezing water is cooled by the cooling tower is fed into a heat exchange unit and exchangesheat with the freezing water on the tail end side of the air conditioner, and the freezing water after heat exchange is fed into the air-conditioning unit and exchanges heat with the air. The air-conditioning refrigeration system comprises the air-conditioning unit, the heat exchange unit, at least two groups of cooling towers and at least two groups of water cooling units, is connected with a circulating pump through a pipeline and switches the refrigeration modes through a valve on the pipeline. The data center comprises the above air-conditioning refrigeration system, the refrigeration modes are switched according to the operating environment of the data center, the air-conditioning water energy is utilized maximally and energy is saved.

Description

technical field [0001] The present invention relates to the field of data center heat dissipation, and more specifically, the present invention relates to an air-conditioning and refrigeration method for a data center, an air-conditioning and refrigeration system, and a data center. Background technique [0002] With the continuous development of the information industry and social economy, the construction scale and quantity of data centers are growing rapidly. The heat dissipation of the data center is also increasing rapidly. In order to ensure the normal operation of the data center, it is necessary to turn on the precision air conditioning system throughout the year to discharge the heat generated by the data center in the computer room. [0003] With the intensification of competition in data centers and the pressure on operating costs, how to achieve energy saving in air conditioning and cooling systems is imminent. The current air-conditioning cooling system has a s...
