Data center refrigeration air-conditioning system

Abstract

The embodiment of the invention provides a data center refrigeration air-conditioning system which comprises a reclaimed water reservoir, a water chilling unit, a plate heat exchanger and an air-conditioning terminal, and the water chilling unit at least comprises a condenser and an evaporator; wherein a first water pump is arranged at the downstream of the reclaimed water reservoir, and an outlet of the first water pump is connected with an inlet of the condenser and a first inlet of the plate heat exchanger through a first pipeline and a second pipeline respectively; an outlet of the condenser is connected with an inlet of the reclaimed water reservoir through a third pipeline; a first outlet of the plate heat exchanger is connected with the inlet of the condenser through a fourth pipeline; and the data center refrigeration air-conditioning system further comprises control equipment which is used for controlling all the pipelines and the water chilling unit to be turned on or turned off according to the water temperature in the reclaimed water reservoir. According to the embodiment of the invention, automatic switching of three operation modes of electric refrigeration in summer, partial natural refrigeration in transition seasons and complete natural refrigeration in winter is realized.

Description

Technical field [0001] The present invention relates to the field of refrigeration and air conditioning technology, and more particularly, to a data center cooling air conditioning system. Background technique [0002] With the development of 5G and artificial intelligence technology, mankind has gradually entered the information, intelligence community, the data center has become popular in new infrastructure projects, but the problem of high energy consumption of data centers more and more prominent, and therefore the construction of energy-efficient data center It is of great significance for energy saving. [0003] Energy consumption of the refrigeration air conditioning system after the information data center energy consuming devices, about 40% of the total energy consumption of data centers, and the cold source of energy and the total cost of data center services refrigeration and air conditioning systems 60 to 70% so cold source is a major factor in refrigeration and air ...

AI Technical Summary

Problems solved by technology

[0005] (1) The operation of the cooling tower in summer brings large energy consumption;

[0006] (2) When the cooling tower is used for cooling in winter, the low temperature environment will cause the cooling water pipes and cooling towers to freeze. If anti-freezing measures such as heating and strengthening insulation are taken for the cooling water pipes and cooling tower water trays, it will not only increase investment, but also improve operation. cost
