The overall energy consumption of the auxiliary equipments such as distribution battery.Information technoloy equipment and air conditioning energy consumption occupy 90% left side of data center's overall energy consumption
The right side, 40% or so is occupied as the air conditioning energy consumption of data center's auxiliary equipment, is only second to information technoloy equipment power consumption.Refrigeration host computer exists
Consumption of data center can effectively be reduced by wherein occupying core position, therefore improving refrigeration host computer efficiency.
Conventional free low-temperature receiver is mainly the outdoor air of winter or spring and autumn at present.Therefore, if it would be possible, data
The area that the addressing at center should be colder in weather or the low temperature time is long.In China, northern area is all very suitable
Close and use free Refrigeration Technique.
For data center's year round cooling application characteristic, cooling by wind is entered with natural cooling source in north cold area
Row combine, can in the winter time, autumn freezed using free natural cooling source (environment temperature) so that efficient electric refrigeration base
The comprehensive raising of annual Energy Efficiency Ratio is realized on plinth.
Comprehensive current natural coldness resource utilizing situation, the natural coldness resource utilizing scheme of presently the most mature and reliable has the following two kinds

Beneficial effect：The new natural cold source refrigerating system that the utility model is provided is by controlling switching to realize 3 kinds
Operational mode：Electric refrigeration mode, natural cooling source pattern and mixed mode (electricity refrigeration is combined with natural cooling source).Electric refrigeration mode with
Traditional natural low-temperature receiver cooling by wind kind of refrigeration cycle is identical, but contrast traditional natural low-temperature receiver Application way, and condenser does not include
Natural cooling source coil pipe, so as to reduce the loss of condenser wind collateral resistance, smaller work(can be selected under same refrigeration and efficiency effect
Rate blower fan, so as to reduce operation power, improves efficiency, because heat exchanger reduces half, so as to reduce material cost.Natural cooling source
Under pattern, refrigerant circulation pump replaces compressor to provide refrigeration system circulation power, compared with traditional pure water scheme, saves centre
The heat exchange loss of heat exchanger, saves natural cooling source system pipeline and anti-icing fluid., i.e. can be with 20 degree of environment temperature under mixed mode
Into mixed mode, need to contrast freezing return water temperature that with traditional scheme higher than environment temperature mixed mode could be entered, according to
16 degree conventional of backwater of current data center is accounted for, its into mixed mode be at least also 15 degree, so as to realize oneself
Right low-temperature receiver makes full use of.
Compared with prior art, new natural cold source refrigerating system of the present utility model is situated between using refrigerant as circulation
Matter, the advantage with glycol solutions and pure water scheme, system need not carry out special antifreeze processing, and natural cooling source is directly changed
Heat, efficiency high, the whole pipeline circulatory system uses pure water, it is ensured that end system heat exchange efficiency and safeguard convenience；It is omitted
Natural cooling source coil pipe, natural cooling source is provided by condenser；Intermediate Heat Exchanger is saved, so as to reduce cost and maintenance complexity.
