Computer room PUE optimizes plan: Computer room PUE optimizes plan refrigeration system energy-saving transform measure
As the flying development of Internet technology, data center already became the important infrastructure that supports modern economy. And the computer room regards data as the center " heart " , management of its specific power consumption is attached most importance to especially should. PUE (Power Usage Effectiveness, electric power uses efficiency) it is the main index that measures data center specific power consumption, reduce PUE value to be able to raise the sources of energy effectively to use efficiency, reduce operation cost. The article discusses development computer room PUE to optimize plan, especially of refrigeration system energy-saving transform measure.
One, PUE and computer room specific power consumption
PUE is the crucial index that measures efficiency of data center energy, it reflected the proportion that total the sources of energy spends data center with IT equipment. PUE cost is lower, state the sources of energy uses efficiency taller. Computer room specific power consumption basically includes IT equipment specific power consumption and refrigeration system specific power consumption two parts.
1.IT equipment specific power consumption: Include equipment of server, storage, network equipment to wait, this part specific power consumption is relatively stable, but promote and increase what follow facility amount and performance.
2.Refrigeration system specific power consumption: Include air conditioning, cooling tower, water pump to wait, this part specific power consumption gets the factor such as bear of environmental temperature, computer room the impact is bigger.
2, computer room PUE optimizes plan
1.Layout of sound program computer room
Computer room layout has immediate effect to PUE value. Equitable distribution can reduce the specific power consumption of refrigeration system. It is a few proposals below:
(1) use modular design, IT facility concentration is set, facilitating concentration manages and safeguard.
(2) passageway of reasonable setting cold heat, ensure cold hot air is detached, improve refrigeration efficiency.
(3) optimize organization of air current of computer room interior, reduce air flow resistance, reduce specific power consumption.
2.Improve refrigeration system efficiency
Refrigeration system is the main source of computer room specific power consumption, it is below a few energy-saving transform measure:
(1) use efficient and energy-saving air conditioning device, wait like frequency conversion air conditioning, water-cooling air conditioning.
(2) optimize cooling tower to run strategy, improve cooling efficiency.
(3) introduce natural cooling technology, if use the cold air outdoor,undertake cooling.
(4) use heat to reclaim technology, will useless heat is used at heating or hot water.
3.Optimize energy management
(1) use intelligent the sources of energy to run a system, real time monitors computer room specific power consumption, implementation specific power consumption is optimized.
(2) temperature of reasonable setting computer room, reduce air conditioning specific power consumption.
(3) use energy-saving illume device, reduce illume specific power consumption.
3, refrigeration system is energy-saving transform measure
1.Optimize air conditioning system
(1) use efficient and energy-saving air conditioning device, wait like frequency conversion air conditioning, water-cooling air conditioning.
(2) optimize air conditioning system to run strategy, if adjust air conditioning operation pattern according to computer room bear.
(3) use intelligence lukewarm control a system, real time monitors computer room temperature, implementation essence allows to control.
2.Optimize cooling system
(1) use efficient and energy-saving cooling tower, if gush drenchs,type of water of type refrigeration tower, gush cools the tower.
(2) optimize cooling tower to run strategy, like the basis environmental temperature adjusts cooling tower operation pattern.
(3) use intelligent refrigeration system, real time monitors cooling result, implementation essence allows to control.
3.Optimize water pump system
(1) use efficient and energy-saving water pump, wait like frequency conversion water pump, intelligence water pump.
(2) optimize water pump to run strategy, if adjust water pump operation pattern according to computer room bear.
(3) use system of intelligent water pump, real time monitors water pump to run state, implementation essence allows to control.
4, summary
Computer room PUE optimizes plan to reducing data center it is specific power consumption, important to raise the sources of energy to use efficiency to have meaning. Through layout of sound program computer room, improve refrigeration system efficiency, optimize the measure such as energy management, can reduce PUE cost effectively, implementation is energy-saving decrease a platoon. In the meantime, of refrigeration system energy-saving transforming also is the key that reduces computer room specific power consumption. Hope the article can be relevant enterprise or the individual provides beneficial reference.
