Description
Technical field
The present invention relates to a kind of data machine room air-conditioning system, be mainly used in the cooling of server in the IDC data center module of all kinds and specification.
Background technology
The existing supporting cooling device of data center module mainly contains precision air conditioner, air-conditioning between row, rack water-cooled Qianmen and cabinet door shape heat exchanger etc., in machine room, toward contact, need to configure humidifier, dehumidifier or constant humidity machine, the control operation system that these air-conditioning equipments are equipped with by self, even if be all arranged in same machine room, also ununified control aspect operation, mutual inaccurate coordination, therefore sometimes may occur that two kinds of contrary methods of operation exist, as part air-conditioning equipment is dehumidifying, and another part is carrying out humidification, or when cold is provided, also need to open electric heating assembly simultaneously, so just caused the counteracting of mutual function effect, the part of this counteracting causes double energy resource consumption.The general quantity of precision air conditioner is more, takies machine room area larger, generally can in machine room, form hot and cold passage, and air intake and supply air temperature difference less, heat transfer effect is lower, each precision air conditioner equipment independence controlling run.The quantity that between row, air-conditioning generally needs is more than precision air conditioner, take machine room area also larger, generally also can in machine room, form hot and cold passage, the in the situation that of the cold passage of sealing, air intake can be slightly larger than precision air conditioner with supply air temperature difference, heat transfer effect is general, and between each row, air-conditioning equipment is also independent controlling run.The humidity of rack water-cooled Qianmen air-conditioning system general tree environment regulates, also need separately to join the air-conditioning equipment of humidity regulation, there is no unified operation control system yet, in addition, in the indoor whole passage of heat that forms of machine room, its machine room integrated environment temperature surpasses country and industry standard, and the relative air humidity that enters rack after the cooling of water-cooled Qianmen is processed can be higher than country and industry standard, interior of equipment cabinet server apparatus is moved always under moister environment, and therefore this mode is not extremely adapted at the use of data center module in fact.Cabinet door shape heat exchanger is a kind of reasonable new technology for data center module, directly press close to thermal source and carry out heat exchange, the outlet and inlet temperature difference is very large, so heat exchange efficiency is high, good energy saving property, adopt this data center module, its indoor environment is all cold passage, and integrated environment is applicable to server apparatus operation, but the humidity of cabinet door shape heat exchanger air conditioner system general tree environment regulates, also need separately to join the air-conditioning equipment of humidity regulation, there is no unified operation control system.
As can be seen here, because data center module heat load is larger, in order to solve its heat dissipation problem, to server, provide a suitable running environment, often in machine room, need the various air-conditioning equipment quantity of layout more, each air-conditioning equipment is equipped with independently control system, air-conditioning equipment is controlled and is disperseed, make air-conditioning equipment operation in data center module mutually lack coordination, equipment maintenance and management personnel will safeguard, arrange and operate every air-conditioning equipment, need the thing of consideration many, increased the complexity of practical operation, and workload is also larger.
