Abstract

The invention relates to a data center emergency cooling system and a control method thereof. The data center emergency cooling system comprises a cooling water system capable of providing cooling water and a cold storage system capable of providing chilled zing water. When outdoor temperature is high, the cold storage system with lower water temperature can be used to provide the chilled water toaccelerate cooling speed of a refrigerant so as to realize emergent refrigeration; when the outdoor temperature is low, only the cooling water system is used to provide the cooling water for a water-cooling condenser to cool the refrigerant, in other words, a natural cold source is utilized to refrigerate a data center so as to avoid continuing using the cold storage system when the temperature is low, so that energy is saved effectively, and the defect that conventional refrigerating schemes need ceaseless cold storage and energy waste is overcome. Compared with the conventional refrigerating schemes, the data center emergency cooling system has the advantages that by arranging the chilled water or the cooling water at an outdoor unit part, emergent refrigerating can be realized withoutthe chilled water or the cooling water entering a data center machine room.

Description

technical field [0001] The present invention relates to the technical field of data center thermal management, and more specifically, to an emergency cooling system and a control method for a data center. Background technique [0002] In recent years, data centers have developed very rapidly, and the development direction tends to be large-scale and modular. How to reduce heat treatment energy consumption is the core of technological development. Under this background, various modular data center solutions that use natural cooling to reduce heat treatment energy consumption have emerged. One of them is the evaporative water-cooled data center refrigerant pump cooling solution, which can replace the current one in terms of energy saving and convenience. Water-cooled chillers or air-cooled chillers + indoor chilled water terminal schemes commonly used in medium and large data centers. [0003] Data centers are divided into security levels. Higher security levels need to be ab...
