Liquid cooling distributed control system and method

Abstract

The invention relates to a liquid cooling distributed control system and method. The system comprises a cooling source, a liquid-liquid heat exchanger and one or more server cabinets; the cooling source is connected with the liquid-liquid heat exchanger through a primary water supply pipe and a primary water return pipe; the liquid-liquid heat exchanger is connected with the server cabinets through a secondary water supply pipe and a secondary water return pipe; and the liquid cooling distributed control system further comprises a cooling source control system for controlling the refrigerationefficiency of the cooling source, a heat exchange control system for controlling the heat exchange efficiency of the liquid-liquid heat exchanger, and a concentrated monitoring system for controllingthe cooling source control system and the heat exchange control system in a concentrated mode. The liquid cooling distributed control system and method not only can achieve point-to-point control ina liquid cooling system, but also can achieve multi-point concentrated control, reduce wiring on the spot and improve the monitoring quality of the liquid cooling system.

Description

technical field [0001] The invention relates to the technical field of heat exchange unit control, in particular to a liquid-cooled distributed control system and a control method. Background technique [0002] According to statistics, my country's data center energy consumption accounted for about 1.8% of the country's total energy consumption in 2015, which is equivalent to the annual power generation of the Three Gorges Hydropower Station of about 100 billion kWh. In the data center, a large amount of energy is wasted by the cooling system, accounting for as much as 40% to 50%, and the PUE value is generally higher than 2.2, which seriously restricts the green and sustainable development of IDC. urgent needs of the platoon. The electrical control system is one of the important key points. [0003] Liquid cooling technology, which belongs to natural cooling technology, is one of the effective ways to reduce the energy consumption of data center computer room. The liquid...
