High-density solution: radical cure room "fever"

In response to the high heat load in the room liebertxd hot-density solution, the solution is flexible, efficient, green, safe, the customer has become the machine room "fever" of the choice.

In the face of the heat density problem in the computer room, the traditional refrigeration system appears powerless. Usually, we use cold air channel isolation, from the bottom of the way to provide the rack of IT equipment refrigeration. This refrigeration mode, in a single cabinet calorific value less than 5kW, if the design is reasonable, can make the overall temperature of the room is controlled. However, if the computer room is larger than 5kW (or even only 3kW) of the cabinet, local hot issues will appear.

The engine room is also an organism, like humans and animals, the body's "fever" will also have a serious impact on the functioning of its parts, and even destroy the entire system. Therefore, how to effectively treat the computer room "fever" has become the focus of the industry discussion.

In response to the high heat load in the room liebertxd hot-density solution, the solution is flexible, efficient, green, safe, the customer has become the machine room "fever" of the choice.

"Flexible" is mainly embodied in the installation and deployment of LIEBERTXD system

The system consists of a refrigeration host (XDP or XDC) and a refrigeration terminal unit (XDH, XDV, Xdo). Among them, the refrigeration host can choose to install in the room or outside the room of other rooms. Refrigeration end there are three ways to choose: three-dimensional installation of the XDH, the XDV installed above the rack, as well as the xdo ceiling installation. XDH suitable for the upper shelf space or low ceiling height, can be deployed in the cold, hot channel layout in the middle of the arrangement of racks; The XDV can be placed vertically on the upper part of the rack, directly absorbing hot air from inside the rack or from the hot channel, after being cooled and released to the cold channel; The XDO is deployed over the cold channel, absorbing the hot air from the rack and releasing the cold channel after cooling.

In addition, the system also provides a variety of cooling methods, including air-cooled, water-cooled, ethylene glycol cooling, etc., to adapt to the different needs of the site, air-cooled condenser can also provide suitable for different temperature environment configuration, the system can also be easily expanded. These also reflect their flexibility.

"High efficiency" is mainly embodied in the refrigeration efficiency of XD system

The refrigeration system can be flexibly placed in the location closest to the main equipment according to the actual needs, with the main equipment racks in accordance with the cold, hot channel isolation arrangement, to the main equipment frame cold channel injection of high density equipment required by the cold, that is to say, can be directly to the cold volume to the room most need refrigeration "hot spot." Compared with the traditional refrigeration system, the "long-distance air supply cycle" has greatly reduced the cross loss of cold and hot air and improved the refrigeration efficiency. In addition, XD system refrigeration Terminal unit with the traditional computer room refrigeration system, can solve a single rack up to 40-kilowatt of the refrigeration problem, very suitable for the configuration of the http://www.aliyun.com/zixun/aggregation/13737.html "> Blade server, such as high density rack of the computer room.

"Green" is mainly embodied in XD system Energy-saving, festival, environmental protection

First of all, compared with the traditional cooling scheme, XD system's energy saving rate is as high as 30%: The system utilizes refrigerant phase change to absorb a large number of computer room sensible heat principle and unique refrigerant control technology, 100% of the cooling output, not only to prevent the production of condensate, but also to avoid the latent cooling output of energy loss; The refrigeration end unit of the XD system is placed in front, close to the load frame, can greatly reduce the energy consumed by the air supply, compared with the traditional air-conditioning long-distance supply wind energy consumption can be reduced by 65%; the system random room equipment heat change automatically adjust the size of the refrigeration capacity can greatly enhance the energy saving effect.

Second, the system's refrigeration host can be placed in other rooms, refrigeration end XDV suitable for placement in the upper part of the rack, and xdo suitable for ceiling installation, so no need to occupy valuable room space, with the advantages of the festival.

At last, the refrigeration host and the refrigeration Terminal unit of XD system are connected through the copper pipe, the inner pipe is filled with r134a environmental refrigerant for heat transfer, and the direct evaporation host system adopts refrigerant environmental refrigerant. Therefore, this is an absolutely "green" refrigeration solution.

"Security" is embodied in XD system eliminates the safety hidden trouble in the water engine room

In the XD system, chilled water refrigeration host located in the room outside the room, through the copper pipe and refrigeration terminal Unit connection, pipeline internal injection R134A environmental refrigerant, you can directly to the top of the rack, to avoid the traditional water cooling system into the computer room to bring security risks. In addition, the refrigeration terminal unit through the host controller to control, to ensure that the evaporator surface temperature is higher than the dew point temperature, to avoid evaporator and refrigerant pipe surface condensation produced condensate water, further improve the safety.
