Embodiment Construction

[0019] Such as figure 1 As shown, an energy-saving control system for dual water-cooling equipment in a machine room includes a main air-conditioning unit, a backup air-conditioning unit, a temperature detection module, a pipeline valve control module, an alarm module, a DDC control module, a communication module and a host computer,

[0020] The temperature detection module includes a temperature detection unit and a temperature signal transmission unit. The temperature detection unit is set on the ceiling above the two rows of cabinets in the machine room. The temperature signal transmission unit adopts the transmission mode of the bus interface. The bus structure can facilitate the establishment of a temperature sensor network, with wiring Simple and flexible features. This method is digital transmission, which greatly improves the anti-interference of the system. It can directly read the measured temperature, and can realize 9-12 digital value reading mode through simple ...

Abstract

The invention discloses an energy-saving control system of machine room double-water-cooling equipment. The system comprises a main air conditioner unit, a standby air conditioner unit, a temperature detecting module, a pipe valve control module, an alarm module, a central control module, a communication module and an upper computer; the main and standby air conditioner units are independently operated; the alarm module periodically reads alarm information on a control chip of the main air conditioner unit; and the upper computer judges if the standby air conditioner unit is started according to failure types and the alarm information of the standby air conditioner unit to automatically finish the cold standby operation of a refrigerating air conditioner in a data center. The system solves the problem of high energy consumption caused by a heat standby mode, saves the energy, and prevents errors in manual operations and potential risks caused by the operation switching impact.

Description

technical field [0001] The invention relates to a control system and method for cold backup of a complex water cooling system in a data center. Background technique [0002] Air conditioning is a big energy consumer, accounting for about 60% of data center energy consumption. This has aroused more and more people's attention and awareness. In recent years, high-efficiency and energy-saving water-cooled air conditioners have been gradually popularized in the world, and great progress and development have been made in the research and development of single outdoor unit control technology. However, due to the continuous growth of cooling demand in data centers, the cooling capacity of the original single unit can no longer meet the actual needs, and the requirements must be further expanded to form a dual-unit or multi-unit refrigeration system. In order to ensure the reliable operation of the data center, the dual-unit refrigeration system often operates at the same time, wh...
