With it is novel be data center's energy conservation cold-storage, cold supply system, this energy conservation cold-storage, cold supply system can make full use of time-of-use tariffs,
The storage that cooling capacity is carried out when low power consumption, makes full use of electricity more than needed, and in response, country is called, and makes full use of the energy, realizes section
It can emission reduction；Let cool at electricity consumption peak, reduce the electricity consumption in rush hour, reduce the electricity cost of enterprise, for
Electric enterprise saves system operation cost.
Utility model content
The problems such as energy-saving and emission-reduction, time-of-use tariffs for country's promotion, data center's refrigeration system electricity consumption is big, this is practical
It is novel to provide a kind of data center's energy conservation cold-storage and cold supply system, peak-trough electricity sufficiently effective can be utilized by this system
Valence realizes energy-saving and emission-reduction and reduces system operation cost.It is described that its technical solution is as follows:
A kind of data center's energy conservation cold-storage and cold supply system, including refrigeration unit, release cold pump, radiator, refrigerating water pump, cold-storage
Tank, refrigeration unit by pipeline respectively with release it is cold pump and cold-storage tank be connected, release it is cold pump be connected with radiator, radiator and cold-storage tank
It is connected respectively with refrigerating water pump, refrigerating water pump is connected with refrigeration unit.
The refrigeration unit is separate unit or more, and exit is equipped with chilled water motor-driven valve.
The inlet and outlet of the cold-storage tank are designed with cold-storage valve.
It is described release it is cold pump be equipped with release cold pump by-passing valve.
The refrigerating water pump is located at the inlet of refrigeration unit, the corresponding refrigeration unit of a refrigerating water pump.
Data center's energy conservation cold-storage and cold supply system can make full use of using time-of-use tariffs, by night electricity consumption
Valley increases refrigeration unit investment, carries out cold-storage to cold-storage tank, a large amount of cooling capacity is stored in cold-storage tank, when electricity consumption on daytime peak
When value, the investment of refrigeration unit is reduced, cold-storage tank is let cool, and stored cooling capacity is released, and is supplied not influencing system
The energy-saving run that system is realized under the premise of cold reduces the operation investment of system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of data center's energy conservation cold-storage and cold supply system.
Specific embodiment
As shown in Figure 1, data center's energy conservation cold-storage and cold supply system include refrigeration unit 1, release cold pump 2, dissipate
Hot device 3, refrigerating water pump 4, cold-storage tank 5.
Refrigeration unit 1 by pipeline respectively with release it is cold pump 2 and cold-storage tank 5 be connected, with cold-storage tank 5 be parallel relationship, release cold
Pump 2 is connected with radiator 3, and radiator 3 and cold-storage tank 5 are respectively connected with refrigerating water pump 4, release it is cold pump after 2 and the series connection of radiator 3 with storage
Cold tank 5 is parallel relationship, and refrigerating water pump 4 is connected with refrigeration unit 1.
The refrigeration unit 1 can be separate unit or more, and exit is equipped with chilled water motor-driven valve 11 or 12.
The inlet and outlet of cold-storage tank 5 are equipped with cold-storage valve 51 and cold-storage valve 52；It is described release it is cold pump 2 be equipped with release cold pump by-passing valve
21；The refrigerating water pump 4 is located at refrigeration unit inlet, the corresponding refrigeration unit 1 of a refrigerating water pump 4.
When system carries out energy saving cold-storage: 1 refrigerating capacity of refrigeration unit increases, on the basis for meeting 3 chilling requirements of radiator
Upper refrigerating capacity further increases, and extra cooling capacity enters cold-storage tank 5, and chilled water motor-driven valve 11 and 12 is fully open at this time, stores
Low temperature valve 51 and cold-storage valve 52 are opened, and are released cold pump by-passing valve 21 and are opened；Rear chilled water is electronic out from refrigeration unit 1 for low temperature chilled water
It is divided into two-way after valve 11 and 12, enters in cold-storage tank 5 through cold-storage valve 51 all the way, another way is released cold pump by-passing valve 21 and enters heat dissipation
Device 3 provides cooling capacity for data center；High temperature chilled water return water after radiator 3 enters refrigerating water pump 4, and low temperature chilled water is through storing
After low temperature valve 51 enters cold-storage tank 5, the high temperature chilled water matter inside cold-storage tank is swapped out, high temperature chilled water return water is through cold-storage valve 52
Into in refrigerating water pump 4, the chilled pump 4 of high temperature chilled water return water for flowing back to refrigerating water pump 4 is got into refrigeration unit 1, completes system
Cold, cold-storage.
When system carries out energy saving cooling supply: refrigeration unit 1 is out of service, and cooling capacity needed for radiator 3 is mentioned by cold-storage tank 5 entirely
For；Constantly chilled water motor-driven valve 11 and 12 is all closed for this, and cold-storage valve 51 and cold-storage valve 52 are made, and is released cold pump by-passing valve 21 and is closed
It closes；The chilled water of low temperature closes since chilled water motor-driven valve 11 and 12 is whole after cold-storage tank 5 comes out, releases cold pump by-passing valve 21
It closes, so chilled water, which is released in cold 2 entrance radiator 3 of pump, provides cooling capacity for data center；High temperature after radiator 3 is cold
Freeze water return water to return in cold-storage tank 5 through cold-storage valve 52, completes cold-storage tank energy conservation cooling supply.
When system carries out cold cooling supply: the operation of 1 part of refrigeration unit, refrigerating capacity need to only meet 3 chilling requirements of radiator
?；Chilled water motor-driven valve 11 and 12 partially opens at this time, and cold-storage valve 51 and cold-storage valve 52 are all made, and releases cold pump by-passing valve 21
It opens；The chilled water of low temperature is after open chilled water motor-driven valve 11 flows out, and since cold-storage valve 51 is closed, bypasses into cold pump is released
Valve 21 is released in the cold entrance of pump by-passing valve 21 radiator 3 and provides cooling capacity for data center, the high temperature freezing after radiator 3
Water return water is since cold-storage valve 51 is closed, and into refrigerating water pump 4, chilled pump 4 enters refrigeration unit after getting, and completes refrigeration cycle.
Above by reference to a kind of Detailed description of the invention embodiment of the invention, those skilled in the art do not depart from the scope of the present invention
And essence, there are many variations to implement the present invention.For example, it is shown as part of one embodiment or describes
Feature can be used for another embodiment to obtain another embodiment.The above is only embodiment of the invention one of oneself, not because
This limiting the scope of the invention, it is all with equivalence changes made by description of the invention and accompanying drawing content, it is both contained in this
Within the interest field of invention.
