Description
Technical field
The present invention relates to a kind of refrigeration system, more specifically, it relates to a kind of data center's cold source system and its operation
Flow.
Background technology
Computer user often pays close attention to the speed (for example, megahertz and GHz) of computer microprocessor.Many people forget
Remember that this speed is often accompanied by cost -- higher electric power consumption.For one or two of home Personal Computer, this excess power
It can be ignored when compared with the cost with running many other electrical equipment in family.But it can operate wherein thousands of
Microprocessor data-center applications in, power demand may be critically important.
The raising of power consumption has both sides to bear in cost for operator.Data center operator not only must
The electricity charge must be paid to operate its many computers, and be necessary for the payment of Cooling calculation machine.Because according to simple thing
Law is managed, all power are all converted to heat energy to the end according to law of conservation of energy.A pair be assemblied on single motherboard are micro-
Processor actual power is 200~400 watts or more power.The numeral is multiplied by into thousands of (or tens thousand of) to be just not difficult to estimate
The substantial amounts of computer that goes out in large-scale data center while work can produce how huge heat heat.
Therefore, it is also likely to be to operate the prime cost of large-scale data center to remove all hot costs.The cost generally relates to
And to the even more multi-energy that type of service is electric power and natural gas come for refrigerator, condenser, pump, fan, cooling tower and its
Its relevant part supply energy makes its normal work.For a large-scale data center, cooling is extremely important, because while micro-
Processor is not as that biology is equally sensitive for high temperature, but heat it is cumulative can typically cause microprocessor make a mistake and therefore
The probability substantial increase of barrier.Sum it up, such system just needs electric power to run chip and need more electric power with cold
But chip.
As modern society's all trades and professions are to the wilderness demand of data, plus the constantly improve of internet, in large data
The heart develops rapidly.Data center server produces many heats when running, and server must at normal temperatures could normal operation,
This just needs special cooling system to cool down this, and the particularity of data center is annual 24 hours uninterruptedly
Operation, the accordingly requirement to cooling system are also to run without interruption；Still further aspect data center is highly energy-consuming equipment, design
