Data center complex water cooling system operation control device and control method

Abstract

The invention discloses a data center complex water-cooling system operation control device and method. The device comprises a water-cooling system, a central controller, a temperature detection device and an electrically operated valve controller. Each water-cooling air conditioner outdoor unit set is connected between a main water-cooling water inlet pipeline and a main water-cooling water return pipeline in parallel through branch pipelines and is communicated with a water-cooling air conditioner indoor unit. Each water-cooling air conditioner outdoor unit set comprises a water-cooling air conditioner outdoor unit, a dry cooling device, an electrically operated valve and an electrically operated three-way adjusting valve. The temperature detection device, the electrically operated valve controller, each water-cooling air conditioner outdoor unit and each dry cooling device are respectively connected with the central controller. The method has three control modes, namely a manual-selection operation control mode, time strategy automatic-operation control mode and a self-optimization control mode. According to the data center complex water-cooling system operation control device and method, potential risks caused by manual operation mistakes and operation switch impact are avoided, the problem of automation control over the multiple air conditioner sets and a pipe net is effectively solved, and maintenance is facilitated.

Description

Technical field [0001] The invention relates to a control device and method of a water cooling system, in particular to an operation control device and a control method of a complex water cooling system in a data center. Background technique [0002] Air conditioners are a big energy consumer, accounting for about 60% of the energy consumption of data centers. This has attracted more and more attention and awareness. In recent years, high-efficiency and energy-saving water-cooled air conditioners have been gradually popularized internationally, and there has been considerable progress and development in the research and development of single outdoor unit control technology. However, due to the continuous growth of data center cooling demand, the original single-unit cooling capacity can no longer meet the actual needs, and it must be further expanded to form a dual-unit or multi-unit cooling system, and the introduction of free dry cooling equipment to use natural gas temperatur...
