Definitions

  • the invention relates to a data centre comprising a building having at least a first floor for supporting ICT equipment, and cooling means for said ICT-equipment which is arranged to subject the said ICT-equipment to a cooling air flow from a cold aisle at a first side of the ICT-equipment to a hot aisle at a second side of the ICT-equipment opposite to the first side.
  • Data centres have gained increased importance with the growing of telecommunication and of data processing and digital data communication within countries and also cross-border. Data centres are quite complex in that they are the result of a joint effort from different engineering disciplines, such as civil engineering, electrical engineering, mechanical engineering and ICT-engineering .
  • One of the problems that relates to known data centres is that the design and size of the building of such data centres, and the required amount of ancillary equipment to be used in the data centre is determined by the expected amount of data- processing and the necessary amount of ICT-equipment that is to be installed for that purpose in the data centre. This means how- ever, that during the life-time of the data centre, only when all the envisaged ICT-equipment is installed the design considerations underlying the economical feasibility of the data centre will prove to be valid. At all other situations wherein the full capacity of the data centre is not used, the costs of operation of the data centre will be too high or at least will not be at a level corresponding to the original design parameters of the data centre .
  • Another problem of the known data centre is that the cooling applied to the installed ICT-equipment, is not always ef- fective and moreover depending on various circumstances relating to the amount of ICT-equipment installed, and also depending on ancillary measures that are taken to secure that efficient cooling air will flow through each separate piece of ICT-equipment. This also means that whenever further ICT-equipment is installed or even if ICT-equipment is removed the cooling conditions of the remaining ICT-equipment will change.
  • the data centre of the invention is preferably characterized by one or more of the appended claims.
  • the cold aisle at the first side of the ICT-equipment is directly or indirectly connected with at least one fan for cooling air, which fan is controllable such that its operation depends on a measured pressure difference between the hot aisle and a pre-selected one of the group comprising the cold aisle and a first room from which the cold aisle receives the cooling air.
  • the fan is controllable such that its operation depends on a measured pressure difference between the hot aisle and a pre-selected one of the group comprising the cold aisle and a first room from which the cold aisle receives the cooling air.
  • the first room occupies the area below the first floor and is arranged to house power lines for feeding the ICT-equipment through said first floor.
  • a first advantage is that the ICT-equipment can be made an exclusive area for maintenance people having to deal directly with the ICT-equipment per se, and that personnel having to deal with for instance powering the ICT-equipment do not have to enter the room for the ICT-equipment, but can do their job in the first room below the first floor supporting the ICT-equipment .
  • the just mentioned advantage is even further promoted by arranging that the building is provided with a walking bridge or bridges suspended from a ceiling above the ICT-equipment, which bridge or bridges are further provided with cable-trays for guiding data-cables to and from the ICT-equipment.
  • This has furthermore the advantage that the data cables can be placed distant from the power lines for the ICT-equipment, therewith effectively reducing undue interference from the power lines on the data transport occurring via the data cables.
  • the building is provided with a floor level below the first room, which floor level is arranged for heavy electrical and mechanical equipment for supporting the operation of the data centre.
  • floor level is arranged for heavy electrical and mechanical equipment for supporting the operation of the data centre.
  • the ICT-equipment can be placed exclusively on the first floor without room on said first floor being taken by other equipment such as power distribution units for powering the ICT-equipment or air handling units for (cooling) the ICT-equipment.
  • An effective use of costly floor area is therefore one of the beneficial aspects of the data centre of the invention.
  • the first room is positioned below the first floor supporting the ICT-equipment.
  • the first room and/or the cold aisle, the hot aisle and the fan or fans are part of a closed circuit for air circulation, which cir- cuit is further provided with one or more air-coolers.
  • An effective use of the available floor area can further be realised by placing the ICT-equipment in two rows, having the cold aisle positioned in-between said rows.
  • the first room from which the cold aisle re- ceives the cooling air connects to an outlet to the cold aisle that is provided in the first floor between the said two rows of ICT-equipment .
  • the said first room from which the cold aisle receives the cooling air has a second supply room for cooling air, which supply room is comprised in said first room and immediately connects to the outlet for cooling air to the cold aisle, and which supply room is further provided with a controllable air-valve or air-valves to control the flow-rate of the cooling air to the cold aisle.
  • a suitable way of providing the controllable air-valve or air-valves is by having them placed in the supply room's wall or walls, and to control the flow rate of the cooling air, depending on a measured pressure difference between the cold aisle and the hot aisle.
  • FIG. 1 shows a part of a data centre in accordance with the invention in a cross-sectional view with particular emphasis to the control of a cooling air flow
  • FIG. 2 shows a preferred embodiment of a data centre in accordance with the invention in a cross-sectional view.
  • a data centre 1 in accordance with the invention having a building 2 with at least a first floor 3, for supporting ICT-equipment 4.
  • the building 2 is also provided with a first room 5, that is provided below the first floor 3 supporting the ICT- equipment 4, and Fig. 2 clearly shows that this first room 5 can occupy the entire area below the first floor 3.
  • the power lines for feeding the ICT-equipment 4 are preferably arranged in this first room 5, such that the required power connections to the ICT-equipment 4 can be provided through the first floor 3 so as to make these power connections to the ICT-equipment 4 as short as possible.
  • a further advantage is that the power lines in the first room 5 are cooled. This reduces energy losses and promotes an optimal dimensioning of the power lines.
  • the building 2 can be provided with a walking bridge, or bridges 6, that is or are suspended from a ceiling 7 above the ICT-equipment 4.
  • Said bridge or bridges 6 are preferably further provided with cable-trays 8 for guiding data cables 2 and from the ICT-equipment 4.
  • this is very beneficial to prevent interference between the power lines that are running in the first room 5 for feeding the ICT- equipment 4, and the data cables that are running through said cable-trays 8.
  • the engineers that need to work with the data cables in the cable-trays can thus be kept out of immediate con- tact with the ICT-equipment 4.
  • FIG. 2 further shows the building 2 can further be provided with a floor level 9, below the first room 5, which floor level 9 is preferably arranged for heavy electrical and mechanical equipment for supporting the operation of the entire data centre 1.
  • This construction not only allows to prevent maintenance people for this heavy equipment to enter the room for the ICT-equipment 4, it is also beneficial for easily moving in or out said heavy equipment, if expansion of the data centre 1 by further ICT-equipment 4 is required and for that purpose addi- tional heavy electrical or mechanical equipment needs to be installed. Likewise, when this equipment needs to be removed for maintenance or other purposes, this can also easily be implemented, without adverse effects on the installed ICT-equipment.
  • Fig. 1 a detail is shown of the building 2, particularly the part of the first floor 3 supporting the ICT-equipment 4, and the first room 5 that is provided below the first floor 3 supporting the ICT-equipment 4.
  • Fig. 1 shows the preferred arrangement that the ICT- equipment 4 is provided into rows 4', 4'' having a cold aisle 10 positioned in between said rows 4', 4''.
  • the cold aisle 10 is thus placed on a first side of the ICT-equipment 4, and from this cold aisle 10, a cooling air flow indicated with arrows 11 is maintained through the ICT-equipment 4 to a so-called hot aisle 12, which is positioned on a second side of the ICT-equipment 4 opposite to the first side where the cold aisle 10 is located.
  • the cold aisle 10 is directly or - as the embodiment of Fig. 1 shows - indirectly connected with a fan 13 for cooling air.
  • This fan 13 is controllable such that its operation depends on a measured pressure difference between the hot aisle 12 and - in the shown embodiment - the first room 5 from which the cold aisle 10 receives the cooling air.
  • a pressure difference transmitter 14 is used that measures the pressure difference between the hot aisle 12 and the first room 5, and that provides its measured pressure difference to a pressure difference controller 15 that controls the fan 13 for cooling air.
  • Fig. 1 further shows that the said first room 5, the cold aisle 10, the hot aisle 12 and the fan 13 are part of a closed circuit for air circulation, whereby this circuit is further provided with an air cooler 16, provided in the return air- duct 17 and a fan 13. Said return airduct 17 provides the connection between the hot aisle 12 and said air cooler 16.
  • Fig. 1 also clearly shows that the first room 5 from which the cooled aisle 10 receives the cooling air, eventually connects to an outlet 18 that is provided in the first floor 3 between the two rows 4', 4'' of ICT-equipment 4. Further, the said first room 5 has a second supply room 19, which supply room 19 is entirely comprised in the first room 5, and immediately connects to said outlet 18 for cooling air to the cold aisle 10.
  • the second supply room 19 is provided with controllable air-valves 20 that control the flow rate of the cooling air (symbolised by the arrows 21) to the cold aisle 10.
  • the controllable air-valves 20 of the second supply room 19 are preferably provided within said supply room's wall or walls, and control the flow rate of the cooling air 21 depending on a measured pressure difference between the cold aisle 10 and the hot aisle 12.
  • a further pressure difference transmitter 22 is used measuring the pressure difference between said cold aisle 10 and hot aisle 12, which measured pressure difference is used as an input signal for pressure difference controller 23, that operates the controllable air-valves 20 of the second supply room 19.
  • this control loop an effective, reliable and stable flow of cooling air 21 can be provided to the cold aisle 10 for cooling the ICT-equipment 4.
