Description
Technical field
The present invention relates to air-conditioning and refrigerating field, particularly a kind of data center focus air-conditioning refrigeration system of using of the air cooling-down of data center's hotspot location.
Background technology
A large amount of electronic equipment cabinets has been installed in the data center, the standardization of the structure of these racks, can add new electronic equipment at any time within it, the PC that sees just as we are daily (personal computer) can add some hardware devices (for example: hard disk, CD drive) etc. at any time within it, as long as wherein also have installing space.
These electronic equipments can produce heat when work, and along with the development of electronics integrated technology, this heat is more and more concentrated and is increasing, the heat that is distributed within unit volume or unit are is more and more in other words, and this development trend has more been quickened in the appearance of " blade server ".
Before and after 2000, the caloric value of 19 inches server cabinets has only 0.5kW-2kW, and the gross calorific power of an at present such server cabinet inside has reached 3kW-7kW, and the caloric value of minority rack is also much bigger.
But, be not that the caloric value of each rack has all reached bigger numerical value, but have only the caloric value of a small amount of rack inside wherein to be increased to bigger numerical value.Excessive when the caloric value of certain or certain several racks of data center, when causing near the too high temperature of air it, just formed described " focus ".This is because the big focus that causes of rack caloric value.
In addition, if the air current composition of original air-conditioning system is bad, cold air can not be sent to some regional area, also can form focus in this zone.
The bigger rack of caloric value that is in hotspot location can not get good cooling, so-called data center machine room hot issue that Here it is.
The scheme that solves hot issue at present has the following:
A takes the panel of rack apart, utilizes fan directly to blow rack internal electronic equipment or device.The rack (rack that caloric value 2kW is following) that this scheme is less to caloric value has certain effect, but the higher rack of caloric value adopts this method just dying.In addition, if during the electronic equipment skewness of rack inside, its effect also can be given a discount.Although this scheme is very direct, also save cost, yet its ability and range of application there is tangible limitation.
B rack that caloric value is bigger is concentrated and is put together, and reconfigures air-conditioning system for these racks.Be understood that this scheme can cause bigger workload, bigger investment, the installation period of long period.In fact, under a lot of situations, also do not possess the feasibility of readjusting machine room layout.
C is that hotspot location is installed the conventional air-conditioning machine: because the conventional air-conditioning machine is bad to the adaptability of machine room, inconvenience is installed, so it is big to use difficulty.Obviously, implement this installation, not only the investment of air conditioner is higher, and mounting cost is also very high, also needs the long set-up time, also needs professional's intervention.
The air-supply of D air duct fixed point: the air supply position from existing air conditioner in machine room machine connects an airduct cold wind is directly delivered to hotspot location, and blower fan is installed on airduct.This method need be carried out site inspection, carries out the airduct design according to the situation at scene.Therefore, this scheme also needs the professional to get involved, and bigger on-the-spot airduct and blower fan installation workload are arranged, and need control blower fan, invests also higherly relatively, and the enforcement time is also longer, under a lot of situations, does not also possess airduct feasibility is installed.
E air duct fixed point exhausting: the air outlet at overheated rack is installed air exhauster and exhaust column, strengthens the ventilation of rack inside, strengthens ventilation, reduces the air output of rack.This scheme also has certain limitation because the air outlet of some rack be not easy to install airduct in other words machine room be not easy to install airduct.Also need the professional to get involved, the implementation process time is also longer, and expense also may be than higher.
F local air circulation a: circulating fan is installed near the raised floor the focus, underfloor cold wind is extracted into hotspot location more.Yet because the air port on the machine room floor is more, cause the air-flow short circuit phenomenon easily, this scheme effect is had a greatly reduced quality.
G industry main flow enterprise U.S. Libert company provides " eXetreme " solution: this is a kind of solution of complexity, also possesses some characteristics.Yet system is very complicated, and cost is very high, and mainly an adaptation is having the machine room of installing space, and is bad for old machine room adaptability.
Also have some other scheme, no longer enumerate at this.In a word, these schemes all have some shortcomings, or even very big defective.
Through the essential analysis of causes to hot issue, through overall understanding to the machine room actual conditions, a kind of focus solution is provided here, can solve data center's hot issue very effectively, and have: initial cost is low, operating cost is low, energy-conservation, flexible and convenient to use, do not need a series of characteristics such as the professional gets involved, plug and play.
Summary of the invention
The purpose of this invention is to provide a kind of data center focus air-conditioning refrigeration system that solves data center's hot issue, it is existing to have solved present data center focus solution: invest height, need problems such as the professional gets involved, the implementation cycle long, it is dumb to use, system complex.
