Abstract

The invention discloses a chilled-water cooling system, which comprises a natural cooling loop consisting of a natural cooler, a chilled-water main pump, a pipeline and an end heat exchanger and a mechanical cooling loop consisting of a chilled-water main engine, a chilled-water auxiliary pump and a pipeline. By controlling a conduction-isolation device between the mechanical cooling loop and the natural cooling loop, the effect of mainly adopting the natural cooler and assistantly adopting mechanical cooling is achieved, thereby reducing energy consumption, improving the efficiency of a refrigeration system and furthermore reducing the cost of the refrigeration system. The present invention is applicable to any place where the natural cooling technology is applied for the purpose of cooling, such as a data center or a machine room.

Description

technical field [0001] The present application relates to a chilled water cooling system, in particular to the chilled water cooling system in the cooling systems of machine rooms and data centers that require long-term cooling. Background technique [0002] Data centers and computer room cooling systems need to use a large number of cooling devices to dissipate heat from servers, storage devices, and network devices. Chilled water systems are widely used in large data computer rooms, switch rooms and other places that require long-term cooling throughout the year. In areas with low temperature, the refrigeration system design of many of these places adopts natural cooling technology, that is, by using the outdoor low temperature, in the transitional season or low temperature season, the chilled water system can use the free outdoor air without cooling by the chilled water host. The cold source saves users a lot of electricity bills. In most data centers in China, the basi...
