Wherein, can by the following method when rack information in acquisition machine room:
The average power consumption of rack is obtained by gathering the electrical parameter being positioned at the row head power distribution cabinet of rack head.
With reference to Fig. 2, wherein Fig. 2 is the typical machine room plane figure according to the embodiment of the present invention.Can find out that the structure of machine room comprises: precision air conditioner 21, rack 22, blasting floor 23.
Its method of operation is as follows:
Lower air-supply organizes the Cryogenic air blown out by machine room Special precision air-conditioning 21 directly to deliver in rack 22 by underfloor air supply plenum chamber (not shown), Cryogenic air gets back to machine room special precision air conditioner 21 top after absorbing the heat of rack 22 from machine room top.
Continue with reference to Fig. 3, as shown in Figure 3, it illustrates each the group structure of rack and composition of equipment, it comprises:
Intelligent electric meter 31, distributing cable 36, row head power distribution cabinet 34, equipment enclosure 37, temperature sensor 32, monitoring optical cable 35, signal picker 33, wherein, row head power distribution cabinet 34 installs intelligent electric meter 31, for surveillance equipment power consumption, at the Qianmen of each equipment enclosure 37, some temperature sensors 32 are installed, for each row's rack installs signal picker 33, be connected with temperature sensor 32, gather the EAT signal of rack.
Technical scheme for a more clear understanding of the present invention, sets forth technical scheme of the present invention in detail with a specific embodiment below.
Please refer to Fig. 4, Fig. 4 is the schematic flow sheet of the air-conditioning system software control method of the embodiment of the present invention, and as can be seen from Figure 4, in software interface, user can Editing Room scene, by the Equipments Setting such as rack, precision air conditioner in system.Or import machine room drawing, or select to preset machine room scene.On software backstage, system understands automatic identification equipment and packet numbering, and the grouping standard of equipment is rack and precision air conditioner.Meanwhile, user can the design temperature upper limit and power consumption lower limit.
After group control system is run, all enter the EAT of cabinet according to the sample frequency collection of setting.
If there is cabinet temperature to exceed capping in group, the temperature of surperficial rack is too high exists hot localised points, then need to open this group air-conditioning, or increases the air-conditioning opened and close in group; If the whole cabinet temperatures in group are all lower than capping, illustrate that cold can meet this group equipment work requirements, then can carry out next step and judge.
In next step process, first judge, so whether the EAT of rack is lower than lowest temperature in group, if meet, then to illustrate that now this group has energy-saving potential, possess one of condition of closing air-conditioning, can be carried out next step and judge; If do not meet, then do not change running state of air conditioner.
In the condition judgment of closing air-conditioning, also need to consider equipment power dissipation, this is because, power consumption can reflect apparatus of load amount, the equipment power dissipation that load capacity is larger is higher, and the cold of needs is also higher.Gather the electrical parameter of first cabinet of each row, the average power consumption of every rack can be conversed.The average power consumption of rack, lower than the power consumption lower limit set, is another Rule of judgment of closing air-conditioning.
Meet rack EAT in group at the same time and, lower than design temperature, under the average power consumption of the rack condition lower than setting lower limit, this group air-conditioning can be closed.
In a machine room, cold meets the radiating requirements of equipment, is a most important condition, and therefore, the cold that in machine room, precision air conditioner produces must be greater than the rated disspation of equipment, and that is, the unlatching number of units of air-conditioning has lower limit; And for ensureing that underfloor cold airflow is even, adjacent air-conditioning can not be closed.
