The present invention will be described in further detail below by way of specific embodiments in conjunction with the accompanying drawings.
Example one
The embodiment provides a data center machine room system.
Referring to fig. 1, the data center room system includes a set of racks 111, a control module 500, a circulating air circuit 130, a mechanical cooling module 200, a back-plate type indirect heat exchange module 300, and a fresh air circuit 400.
Wherein, the circulating air chamber 120 is provided with an outlet and an inlet which are arranged at two sides of the surface air cooler 121, the outlet and the inlet of the circulating air chamber 120 are respectively communicated with the equipment placing chamber 110, and the outlet and the inlet of the circulating air chamber 120 are distributed at two sides of the cabinet 111; the air in the circulating air loop 130 enters the machine room 100 from the outlet of the circulating air chamber 120 under the driving of the circulating fan 122, passes through the IT equipment in the machine room 100, and enters the circulating air chamber 120 from the inlet of the circulating air chamber 120.
In addition, referring to fig. 4 and 5, the heat dissipation channel 320 of the backplate type indirect heat exchange module 300 is provided with a heat dissipation air outlet 323 and a heat dissipation air inlet 322, and the outdoor cold air provided by the fresh air loop 400 enters from the heat dissipation air inlet 322, passes through the heat dissipation component 321, and is then discharged from the heat dissipation air outlet 323; a relay booster fan 324 is arranged on the heat dissipation air outlet 323; the heat absorbing passage 310 has a heat absorbing air inlet 312 and a heat absorbing air outlet 313, the heat absorbing air inlet 312 is communicated with the equipment placing chamber 110, the heat absorbing air outlet 313 is communicated with the circulating air chamber 120, and air in the circulating air loop 130 passes through the IT equipment, enters from the heat absorbing air inlet 312, passes through the heat absorbing part 311, and enters from the heat absorbing air outlet 313 into the circulating air chamber 120. Meanwhile, the fresh air module 410 further includes a fresh air filter 413 and a direct evaporative cooling device 413. The outdoor cold air passes through the fresh air module 410 can filter, cool and then be sent into in the heat dissipation channel 320, certainly also can only pass through the filtration and let in the heat dissipation channel 320 through not cooling. In other words, when the outdoor temperature is lower than a certain set value, the fresh air fan 411 is used to send the outdoor cold air into the heat dissipation channel 320, and then the relay booster fan 324 is used to discharge the outdoor cold air out of the heat dissipation channel 320; in this process, the outdoor cold air is further cooled by the direct evaporative cooling device 412; then, the outdoor cold air cools the medium inside the heat dissipating member 321 inside the heat dissipating channel 320, and the medium cooled inside the heat dissipating member 321 is transferred into the heat absorbing member 311, so that the heat absorbing member 311 cools the air in the circulating air circuit 130. Therefore, when the mechanical refrigeration module and the fresh air module 410 are used for cooling the IT equipment, the hot air passing through the IT equipment in the machine room 100 is cooled for the first time through the heat absorption part 311 and then is cooled for the second time through the surface air cooler 121. Wherein, the heat absorbing member 311 may be an evaporator, and the heat dissipating member 321 may be a condenser; the heat absorbing member 311 and the heat dissipating member 321 may be of a split structure, and the heat transfer is achieved through a heat transfer medium therebetween, or may be of an integral structure, and the heat transfer is achieved through a heat exchanging device itself.
It should be noted that the operation mode of the data center room system changes according to the outdoor temperature and the temperature in the room 100. In the following description, off/on refers to turning off/on a module, and load/unload refers to increasing or decreasing the output of a module.
Specifically, when the outdoor temperature is higher than a certain set value, the fresh air module 410 is closed, and only the mechanical refrigeration module is opened; when the temperature in the machine room 100 is higher than a set value, the mechanical cooling module 200 is loaded, a cold source provided for the surface air cooler 121 is increased, and the cold source exchanges heat with the air in the circulating air loop 130 for refrigeration; otherwise, the mechanical cooling module 200 is unloaded.
When the outdoor temperature is lower than a certain set value, the fresh air module 410 is started first, and when the temperature in the room 100 is higher than a certain set value, the fresh air module 410 is loaded; if the temperature in the machine room 100 is still higher than a certain set value after the fresh air module 410 is loaded to the maximum, the mechanical cooling module 200 is started, and the mechanical cooling module 200 is loaded until the temperature in the machine room 100 reaches a certain set value; otherwise, the mechanical cooling module 200 is unloaded first until the mechanical cooling module 200 is closed, and then the fresh air module 410 is unloaded.
In the above process, since the machine room 100 of the data center has a requirement for the air volume, even when the IT equipment is cooled only by the fresh air module 410, the circulating air fan must be turned on to make the air volume in the machine room 100 meet the requirement. In addition, when the fresh air module 410 is unloaded, the direct evaporative cooling device 412 may be unloaded first until it is turned off, and then the fresh air fan 411 may be unloaded; otherwise, the fresh air fan 411 is loaded first, and then the direct evaporative cooling device 412 is loaded.
In some embodiments, in order to make the circulating cool air of the circulating air loop 130 better act on the IT equipment, the cabinet 111 is a ventable structure, and the cabinet 111 divides the inner space of the equipment placing chamber 110, so that the air on one side of the cabinet 111 in the machine room 100 must pass through the cabinet 111 to enter the other side of the cabinet 111. Therefore, the cold energy discount caused by the mixing of the cold air before passing through the cabinet 111 and the hot air after passing through the cabinet 111 can be avoided, and the energy consumption of the mechanical cooling module 200 is reduced. If the space in the equipment placing chamber 110 is large and the size of the cabinet 111 is small, and the cabinet 111 cannot separate the equipment placing chamber 110 well, a cabinet partition 112 may be disposed in a gap between the cabinet 111 and the equipment placing chamber 110, so as to separate the equipment rooms 100.
In some embodiments, the circulating air chamber 120 is disposed below the equipment placing chamber 110, and the circulating air chamber 120 is disposed in an overhead ground platform. Therefore, the occupied area of the whole data center machine room system is reduced, the structure is optimized, and the safety is higher. In addition, in order to facilitate maintenance of the mechanical cooling module 200, the mechanical cooling module 200 may be disposed outdoors; the mechanical cooling module 200 may be composed of a condensing fan, a condensing coil, a refrigeration compressor, and the like, and the form is not limited to a water-cooling or air-cooling chilled water system, a VRV multi-split system, and other mechanical cold sources. In addition, a fresh air chamber 420 is further arranged in the platform, the fresh air chamber 420 is communicated with the heat dissipation air inlet 322 of the heat dissipation channel 320, and the fresh air fan 411 sends outdoor cold air into the fresh air chamber 420 and then enters the heat dissipation channel 320.
In some embodiments, for example, a worker entering the machine room 100 to perform maintenance on IT equipment may cause more dust to enter the machine room 100; therefore, the circulating air filter 123 may be disposed on the path of the circulating air loop 130, so that when the air in the circulating air loop 130 flows, the dust is driven to flow, and the dust falls into the circulating air filter 123, and the worker may clean the circulating air filter 123 periodically. Since the machine room 100 of the data center also has a certain requirement for humidity, a humidifier may be provided on the path of the circulating air circuit 130, and the humidifier is not limited to a humidification form such as an electrode humidifier or a high-pressure spray humidifier.
It should be noted that, the back-plate type indirect heat exchange module 300 may only locate the heat absorbing channel 310 inside the machine room 100, and locate the heat dissipating channel 320 outside the machine room 100, so that after the air inside the machine room 100 passes through the cabinet 111, the air must pass through the heat absorbing channel 310 to enter the circulating air chamber 120; the back plate type indirect heat exchange module 300 may also be configured such that the heat absorption channel 310 and the heat dissipation channel 320 are disposed in the machine room 100 at the same time, but the outdoor cold air in the heat dissipation channel 320 is not communicated with the air of the circulating air loop 130, and an opening is disposed on the machine room 100 at a position corresponding to the heat dissipation air outlet 323 of the heat dissipation channel 320, so as to facilitate discharging the outdoor cold air in the heat dissipation channel 320.
Example two
The embodiment also provides a data center machine room system.
Referring to fig. 2, the data center room system includes a set of racks 111, a control module 500, a circulating air circuit 130, a mechanical cooling module 200, a back-plate type indirect heat exchange module 300, and a fresh air circuit 400. The machine room 100 of the data center machine room system is arranged in the exhaust room 600, and the exhaust fan 610 is arranged on the exhaust room 600. The structure described in the first embodiment can be applied to the second embodiment, and the working method of the second embodiment is the same as that of the first embodiment, and therefore, the description thereof is omitted.
Compared with the first embodiment, the difference is that the second embodiment can avoid the influence of the external environment on the machine room 100, such as the influence of the harsh natural environment like sunlight, rainstorm, frost and snow.
In addition, in the operation process of the data center machine room system, when the outdoor temperature is lower than a certain set value, the cooling capacity obtained by the back plate type indirect heat exchange module 300 from the outdoor cold air is enough to meet the requirement of heat dissipation of the IT equipment. When the number of the used IT devices is reduced or the heat productivity of the IT devices is reduced, the relay booster fan 324 of the back plate type indirect heat exchange module 300 can be unloaded to meet the requirement that the temperature of the IT devices reaches the set value. When the output of the relay booster fan 324 is reduced, the negative pressure value of the fresh air chamber 420 is reduced, the air volume of the fresh air fan 411 is unloaded to maintain the negative pressure set value of the fresh air chamber 420, meanwhile, the positive pressure value of the exhaust chamber 600 is reduced, and the air volume of the exhaust fan 610 is unloaded to maintain the positive pressure set value of the exhaust chamber 600. This prevents outdoor dust from entering the exhaust chamber 600 from the position of the exhaust fan 610. According to the use condition of the IT cabinet 111, the relay booster fan 324 is started and stopped, and the exhaust fan 610 and the fresh air fan 411 are dynamically connected in series to realize adjustment according to requirements; the output of the exhaust fan 610, the fresh air fan 411 and the relay booster fan 324 is adjusted according to the requirement, so that the energy consumption of the data center can be effectively reduced, and the energy-saving effect is achieved.
It should be noted that, in the above process, the relay pressurization fan 324 and the fresh air fan 411 are linked, and do not conflict with the unloading manner of the fresh air module 410 in the first embodiment.
