It is obtained by the comparative analysis to above-mentioned two table, capital equipment (dry model, wet mould under two kinds of operating conditions
Formula) annual operation power consumption is consistent, and auxiliary refrigeration device whole year operation energy consumption is different, and the temperature for improving outer circulation cold air can be reduced
The power consumption of auxiliary refrigeration device.
Optionally, the air-treatment unit 01 of notebook data central machine room is duplex feeding, and specifically, alternating current supplies all the way
Electricity, UPS powers all the way, is powered when alternating current power-off by UPS, is powered after diesel-driven generator starting by diesel-driven generator,
To guarantee the uninterrupted refrigeration of data center machine room.
The mains-supplied: the industrial-frequency alternating current (AC) of alternating current, that is, usually said, alternating current commonly use three amounts to characterize:
Voltage, electric current, frequency, data center machine room are typically led to three-phase 380V, and the alternating current of 50HZ is as power supply, but data center computer room layer
The power rectifier module for the equipment given in 03 be single-phase 220V voltage.
UPS (uninterruptible power supply) power supply: UPS is arranged to solve uninterrupted power supply, is by battery
It is connected with host, direct current is converted into the system equipment of alternating current by modular circuits such as host inverters.
Beneficial effects of the present invention: air-treatment unit 01 is arranged in data center computer room layer 03 data center machine room of the present invention
Upper layer, compared with the existing technology in air-treatment unit 01 is arranged in the two sides of data center computer room layer 03, air of the invention
Unit 01 is handled there is no the area occupied in data center machine room, data center machine room is enabled to accommodate more equipment,
And the method for indirect evaporating-cooling of the present invention is more energy efficient；The present invention is simultaneously in air-treatment unit 01 and 03, data center computer room layer
Hot return air interlayer 02 is set, and the hot return air interlayer 02 can neutralize the heat generated in data center computer room, avoid at air
It manages unit 01 and generates hot localised points；For example, if the temperature that a certain equipment generates is higher, heat can be generated with other equipment
Heat in hot return air interlayer 02 in and, so that air-flow mobility is more preferable；Also, add the heat dissipation area of an interlayer more
Greatly, it is more advantageous to cooling for data center machine room.The present invention can be according to the temperature of outer circulation cold air, at air simultaneously
Reason unit 01 selects different refrigeration modes in turn, can be adapted for the refrigeration under different temperatures, refrigerating method of the invention is more
Supernumerary segment energy.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
