The utility model content
The purpose of this utility model provides a kind of energy and will all blow directly to introduce in each layering of interior of equipment cabinet computer equipment is cooled off, the efficient of raising equipment operation, and the wind pushing temperature of each layer of control interior of equipment cabinet reaches unanimity, and then reach each layer and have identical cooling effect, assurance equipment is long-term, safety, the novel computer-room air conditioning system based on floor blowing of stable operation.
The technical scheme of the utility model purpose is a kind of novel computer-room air conditioning system based on floor blowing, the cold/hot water output water pump input of air-source cold/hot water unit, the input of water pump output termination valve with electrically motorized operation, the first input end of the output termination air-conditioning box of valve with electrically motorized operation, the input of the first output termination air-source cold/hot water unit of air-conditioning box; The second output of air-conditioning box connects the air input in room by the first pipeline, and the air output in room connects the second input of air-conditioning box by second pipe; Air-conditioning box the 3rd input communicates with atmosphere; Interior air-supply rack places on the raised floor, and the air outlet of the air-supply passage of interior air-supply rack and the air outlet of raised floor join.
Air outlet size and the putting position just coincide of the air-supply passage of the air outlet of raised floor and interior air-supply rack.
The rack of blowing in one can be put in the room, also can put the rack of blowing in many.
Interior air-supply Door of communication apparatus cabinet is the dual-layer vacuum glass door, and the back door is barrier through hole door.
The air supply duct of interior air-supply rack can be installed in the one-sided of Qianmen, also can be installed in the both sides at Qianmen.
The air-supply passage of interior air-supply rack is the ventilating board of porous.
The beneficial effects of the utility model are:
(1). the utility model combines Under-Floor Air-conditioning System and interior air-supply rack, directly send into the anterior air-supply passage of interior air-supply rack through the air-supply that air-conditioning box is processed by the floor plenum chamber, will blow in each layering of sending into respectively interior of equipment cabinet by the orifice plate of air-supply passage again.Thereby to server, computer, the equipment such as router cool off, and then discharge by the barrier passage at rack back door.System of the present utility model directly delivers to air-supply near each layering computer, therefore allows higher wind pushing temperature, and then improves the supply water temperature of air-source cold/hot water unit, improves Energy Efficiency Ratio, energy savings.
(2). the wind pushing temperature that system of the present utility model sends into each layering of rack by the air-supply orifice plate of interior air-supply rack air-supply passage equates substantially or approaches that each layer apparatus cools effect is basically identical, and assurance equipment is long-term, safety, stable operation.
(3). system of the present utility model only need pay close attention to the supply and exhaust temperature of interior of equipment cabinet, needn't be concerned about the temperature in whole room, can improve the temperature difference of air blow and return, in the certain situation of load, the air blow and return temperature difference improves, and air output will reduce, thereby improve the efficient of blower fan, energy savings.
