Determine power 800kW diesel-driven generator), also it is a set of cooling back-up system (down power 500kW compression refigerating machine group and
400kW water-cooling system).These energy back-up systems considerably increase investment, run and safeguard (operating and
Maintenance, O＆M) cost (diesel-driven generator of about 203495 yuan/year expends, and the standby cooling of 44210 yuan/year expends).Cause
This, data center using the system as after main energy resource system will can be effectively saved investment and O＆M costs.
According to DFC3000 models, DFC3000 is one to be had the running situation of fuel cell (Fuel Cell, abbreviation FC)
2.8MW power, based on fused carbonate, natural gas for fuel combined generating system.The service life of fuel cell and
O＆M costs depend on factors, and the present invention will be such that fuel battery service life reaches 5 years, and O＆M cost control is in 220 yuan/MW
Within.DFC3000 is equipped with a double-effect absorption refrigerating machine, has 1400kW refrigeration work consumption, the coefficient of performance 1.3, cold water
6-7 DEG C of temperature, and 360kW, 50 DEG C of vapor are discharged after absorption cycle.Cold water from absorption cycle can cool down highest 16
DEG C air, then these air be admitted to the cooling system of encapsulation of data with cooling large-sized computer.Discharged from cooling system
Air themperature at 35-45 DEG C, the temperature depends on the load of mainframe computer, and these heats are also available for other office sectors
Use.When winter cold, the thermal power of these recovery is up to 430MW, equivalent to the heating fee for saving 220884 yuan/year.Table 1
Provide the input data of related simulation calculation.
Table 1 emulates input data
The fuel cell-hot and cold, cogeneration system (abbreviation FC-CCHP systems) can be that data center saves about 6005000
The operation in member/year is power-consuming, including electric power, cooling, heating and back-up system are safeguarded.It is contemplated that after fund cost, the system
The economic loss of about 233700 yuan/year will be had.This shows, with regard to current energy prices and the national dynamics of investment to technology
Speech, the economic benefit of FC-CCHP schemes are not ideal.
According to the prediction of World Bank staple commodities, with exploitation, the development of transportation technology, the price of following natural gas will under
Drop.The energy trend report of European Union 2030 also indicates that commercial power price is estimated will to be increased with average 5% speed every year.It is assumed that
Gas Prices keep constant, power price rise 3%, and cooling and 2%, the O＆M costs that go up in heat supply price year also go up every year
2%, now FC-CCHP systems have a good economic benefit, EACF values are about 3152000 yuan/year.
When providing cooling service, because FC has higher thermal power ratio so that the electric power that data center is produced is remote
Exceed well over required electric power.There are two links to produce additional power, first, reaching CCHP electric refrigerations optimum proportioning (about
For 1:10) cooling load consumption can now, be greatly reduced by being directly incorporated into conventional electric power cooling system.If second, it is by this
Data center of the system applied to campus, system can produce more electric power and be used for data center, and at the cooling of region
Obtain extra cooling power, so can save more electric power than original Run-time scenario, now about 611300 yuan of EACF values/
Year.But when system meets the electric load demand of data center, it will terminate power supply, can retrieve extraneoas loss about herein
3167000 yuan/year.FC of future generation is estimated will 7 years service life, and now FC enterprises will provide the product operation maintenance of 10 terms
With guarantee.If this 10 year guarantee period is taken into account, the EACF for there are about 692000 yuan/year is lost.
Above-mentioned analysis result has been summarised in table 2, and EACF is influenceed very greatly by energy prices change, natural gas and electric power valency
The 50% and 56% EACF changes that the year change of lattice 1% will be brought respectively.This means what is sharp risen in power price
In the case of, data center is equipped with FC-CCHP systems can be very economical.
EACF under the different scenes of table 2
As country is advocated energy-saving and emission-reduction, data center will be had using fuel cell-hot and cold, cogeneration system
Very high efficiency of energy utilization and economic benefit.With the extension of fuel battery service life, the change of future source of energy price with
And subsidy and the tax incentive of government, it is overcast that fuel cell-hot and cold, cogeneration system will provide high-quality to data center
This heating, cooling, electrical power services.
