Data center liquid-channel and gas-channel precise and efficient cooling system and control method thereof

Abstract

The invention discloses a data center liquid-channel and gas-channel precise and efficient cooling system and a control method thereof. The system comprises a data center micro module machine room, a liquid cooling channel refrigerating system and an air cooling channel refrigerating system; the system further comprises a cold source backup bypass system; and the cold source backup bypass system is connected with the liquid cooling channel refrigerating system and the air cooling channel refrigerating system and is used for switching the cooling media of the cooling channel refrigerating system and the air cooling channel refrigerating system. According to the method, the control system of the liquid cooling channel refrigerating system realizes the backup switching of the cold source-side cooling media of the liquid cooling channel refrigerating system and the air cooling channel refrigerating system through controlling and adjusting a first bypass electric valve, a second bypass electric valve, a first liquid cooling electric valve, a second liquid cooling electric valve, a first air cooling electric valve and a second air cooling electric valve according to the cold load demand of a liquid channel and a gas channel and ambient temperature change. The data center liquid-channel and gas-channel precise and efficient cooling system and control method thereof of the invention have the advantages of high reliability, high safety and cold source cooperative control performance. With the data center liquid-channel and gas-channel precise and efficient cooling system and the control method thereof of the invention adopted, the shutdown of a large number of servers caused by the failure of a single device or a single refrigerating system can be avoided.

Description

technical field [0001] This patent belongs to the technical field of refrigeration for server equipment, in particular to a liquid-gas dual-channel precise and efficient refrigeration system for a data center and a control method thereof. Background technique [0002] Large-scale data centers have played an important role in the process of globalization and informatization development. They are important infrastructure for industries such as telecommunications, the Internet, and finance. They are also an important informatization foundation for countries to promote the strategy of network power. [0003] In recent years, with the accelerated development of the Internet, cloud computing and big data industries, the pace of global data center construction has accelerated significantly, with a total of more than 3 million, and the market size will exceed 106 billion yuan in 2018. At the same time, according to statistics, the annual power consumption of data centers accounts fo...
