Embodiment 2
With reference to Fig. 2 data center data center module and office building air conditioning heating structure connection diagram; Certain data center described in the present embodiment builds together three office buildings and a data center module.
Office building adopts central air-conditioning system, and summer cooling heat supply in winter, design total refrigeration duty 7300Kw summer, winter designs total heat duties 4900Kw.Data center module needs cooling throughout the year, and refrigerated air-conditioning system presses n+1 standard design, overall design refrigeration duty 27500Kw.
Due to data center module, heating season still needs cooling in the winter time, produces a large amount of heat dissipation simultaneously, and this partial heat as the heating reservoir of office building, i.e. Waste Heat Reuse, can substitute pipeline for gas, reduces fossil energy and uses.In addition, according to local climate condition, data center module cooling in winter also can adopt cooling tower freely auxiliary cooling mode, reduces energy consumption.
Consider office building data center module early stage build, office building low-temperature receiver is not built jointly with data center module low-temperature receiver, and consider arrange boiler room as office building heating early stage thermal source and data center module build up after standby heat source.
Office building low-temperature receiver has selected three 2150Kw centrifuges and a 1230Kw screw machine altogether, selects two as source pump in three desk centrifuges, to data center module cooling while heating to office building in the winter time.Data center module low-temperature receiver is arranged respectively by two machine rooms, and each machine room bears 50% of total refrigeration duty.Four 4570Kw centrifuges (three is standby with) selected by each machine room, and configure cooling tower, chilled water circulating pump and cooling water circulating pump one to one.Because office building thermic load in winter is only equivalent to 30% of data center module single cold group heat exhaust, office building source pump only need from data center module cold group heat-obtaining.

3, when outdoor dry bulb and wet bulb is reduced to a certain degree, free cold supply of cooling column amount and office building heat pump semen donors sum are greater than data center module refrigeration duty, now data center module cold is closed completely, cooling tower cooling becomes controlled low-temperature receiver, needs controlled cooling model tower semen donors to realize controlling supply water temperature T1 (T1=t2).
By adopting technique scheme disclosed in the utility model, obtain effect useful as follows:
1, between each Cooling and Heat Source and and user side recirculated water between flow-control completely independent, namely G, g1 ... onrelevant between gn-1, gn.
2, Cooling and Heat Source can add unloading flexibly, can adjust the load of each Cooling and Heat Source according to efficiency of energy utilization at any time.
3, Cooling and Heat Source can arrange by energy grade, and first user side backwater flows through low-grade Cooling and Heat Source, then flows through comparatively high-grade Cooling and Heat Source successively, makes full use of low-grade Cooling and Heat Source.
4, only need a controllable source play the effect controlling user side supply water temperature (T1) in multiple Cooling and Heat Source, other sources can be controllable source and also can be and do not control source, and source of not controlling can be unstable source.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
