Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As it is shown in figure 1, be Multilayer datacenter cooling system, its top is the cooling system being arranged on top layer, its underpart
For being arranged on the cooling system of other floors.
This system includes data center machine room 1 and the cooling unit 2 being arranged in data center machine room 1, wherein cools down
Unit 2 is distributed in every layer of data center machine room 1.The air that indoor air circulation in data center cooling system is airtight follows
Ring, room air is cooled down by cooling unit 2.
Furred ceiling 3 and lower furred ceiling 4 are set in data center machine room 1, upper furred ceiling 3 wind output channel 5 outer with body of wall forming chamber, on
Furred ceiling 3 and return airway 6 in lower furred ceiling 4 forming chamber.
Cooling unit 2 includes evaporating refrigerating module 2a, fan coil module 2b, blower fan maintenance channel module 2c and air draft wind
Machine module 2d, indoor air circulation carries out heat exchange by evaporation refrigerating module 2a with outdoor air.
Fan coil module 2b includes coil pipe wall and indoor fan；Can be convenient by dismounting blower fan maintenance channel module 2c
To cooling unit 2 carry out maintenance overhaul.
Data center machine room 1 is multiple structure, is distributed in every layer of building；When data center machine room 1 is positioned at roof, row
Air port 5b is positioned on roof or the sidewall away from cooling unit 2；When data center machine room 1 is positioned at other floors, exhaust outlet 5b
It is located remotely from the sidewall of cooling unit 2.Exhaust fan module 2d is arranged on exhaust outlet 5b.
Wherein, exhaust outlet 5b number 1, cool down unit 2 number 1.
Meanwhile, cooling unit 2 can also be arranged in independent air conditioning room.
Wherein, septal pathways 7 compartment outer air and room air so that it is separate.
The present embodiment 1 is with the difference of embodiment 2: exhaust fan module 2c is arranged on evaporation refrigerating module 2a's
Top.(shown in Fig. 2)
As shown in Figure 1 and Figure 2, cooling system has two air flow paths
One, indoor air circulation
Cold wind after cooling is sent into data center machine room 1, the heat of equipment in data center machine room 1 by fan coil module 2b
Amount spills in air, and the temperature rises to absorb the room air of calculator room equipment heat, and flows into indoor return air air channel 5 in and evaporate
Refrigerating module 2a, carries out heat exchange with outdoor cold wind at evaporation refrigerating module 2a.
When the indoor air temperature after heat exchange meets data center machine room 1 design temperature, by fan coil module
2b is sent directly in data center machine room 1；
When the air themperature after heat exchange is unsatisfactory for data center machine room 1 design temperature, the machine of fan coil module 2b
Tool refrigeration is opened, and further cools down room air, it is ensured that sends into the air themperature in data center machine room 1 and meets and set
Two, outside air-flow
Outdoor air-flow is driven by outdoor exhaust fan module 8, and outdoor air enters evaporation by outdoor wind inlet channel
Refrigerating module 2a, when its temperature is of a sufficiently low, directly at the heat exchange core body in evaporation refrigerating module 2a with indoor hot-air
Carry out heat exchange, then flow through outdoor wind output channel 6 and be discharged in environment；
When the temperature of outdoor air is unsatisfactory for indoor refrigeration demand, outdoor air is sprayed by evaporation refrigerating module 2a
Evaporation cooling, it is ensured that outdoor air has enough colds；Further it is not met by when the outdoor air after evaporation cooling
During exchange capability of heat, evaporation refrigerating module 2a opens mechanical refrigeration, is further cooled down room air, meanwhile, and Jing Guohuan
Condenser is cooled down by the outdoor air after hot core body, more energy-conservation.
Outdoor air and room air carry out heat exchange by evaporation refrigerating module 2a, separate are not in contact with each other, room
Interior air will not be polluted by outdoor air, thus delays the service life of equipment.And the volume little energy layout of cooling unit 2
In the data center machine room 1 of each floor, good effect of heat exchange.
