The design scheme of hydrophone；Secondly, the configuration of a set of large-scale cold source system of configuration substitution by two sets of small-sized cold source systems, by air-conditioning
Pipe-line system breaks the whole up into parts；It is supplied finally, computer room end system pipeline is adjusted to loop by two-way supply.
1) the data center's cold source system introduced in the embodiment of the present invention has the advantage that using for water loops and return water
The design scheme of loop meets the requirement without Single Point of Faliure to substitute the design of traditional water segregator and water collector；Due to using
The problem of loop design, entire cold source system is paralysed when avoiding valve fittings failure at water segregator or water collector, when in ring
When any side on road break down, valve shutdown isolation can be used and repair, while guaranteeing chilled water in the other side of loop
Regular supply, improve the reliability of cold source system；2) by the configuration of a set of large-scale cold source system be adjusted to two sets it is small-sized cold
The configuration of source system, air conditioning pipe system is broken the whole up into parts, conducive to the processing of the water accident such as O&M and pipeline burst；Due to air-conditioning
System breaks the whole up into parts, and main line caliber is opposite to become smaller, and the reply of the water accident after being conducive to primary pipe rupture is also advantageous daily
Maintenance；Simultaneously as cold source main system uses two sets of independent air-conditioning systems, even if there is catastrophic failure in single set system,
Another set of system can still ensure the cold source abundance supply of emphasis computer room；3) air conditioning terminal pipeline is adjusted to loop confession by two-way supply
It answers, meets end system without Single Point of Faliure requirement, its corresponding air conditioner in machine room is unable to run when solving pipeline fault all the way
Problem.
By the explanation of specific embodiment, the present invention can should be reached technological means that predetermined purpose is taken and
Effect is able to more deeply and specifically understand, however appended diagram is only to provide reference and description and is used, and is not used to this
Invention limits.
