Description
Technical field
The utility model relates to aircondition, especially relates to a kind of energy-saving air conditioning system that is used for data center.
Background technology
In data center, the energy consumption of air conditioner in machine room has accounted for more than 40% of total energy consumption, has quite great proportion, and therefore, the energy-saving run of air conditioner in machine room is the important breakthrough point of each operator's energy-saving and emission-reduction action.Air conditioner in machine room has the characteristics of round-the-clock running, when outdoor environment temperature is lower, makes full use of natural cooling source and replaces compressor operating, is the important directions that reduces the air conditioner in machine room energy consumption.The existing method of utilizing natural cooling source to freeze comprises the pump circularly cooling.I.e. integration pump circulation in original air conditioner in machine room utilizes compressor cooling when outdoor environment temperature is higher, when outdoor environment temperature is lower, utilize pump to circulate and freeze, and compressor and refrigerated medium pump utilize same set of evaporimeter and condenser.This scheme must each refrigeration system all dispose a cover pump circulatory system, the machine set system complex design, and cost is very high, and customer investment is very big; The characteristics of refrigerated medium pump normally flow are bigger; And the flow of the single refrigeration system of air conditioner in machine room is also little usually, often all in the characteristic low discharge of refrigerated medium pump district, causes the operating point of pump own to depart from best operating point; The low load with strong power of promptly saying usually, efficient is not high; And this application only is adapted on the air-cooled air conditioner in machine room, on water-cooled, chilled water air conditioner in machine room, can't use.
The utility model content
The purpose of the utility model is to solve the problem that exists in the above-mentioned prior art, proposes a kind of energy-saving air conditioning system.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is a kind of energy-saving air conditioning system of design, comprises indoor set and off-premises station, and wherein: described indoor set comprises the evaporator bank of a parallel connection; The feed tube place of each evaporimeter is provided with magnetic valve; Described off-premises station is made up of condenser group, a reservoir and a refrigerated medium pump of a parallel connection, and described indoor set is connected with described condenser group through pipeline, and the outlet of condenser group is connected with reservoir, refrigerated medium pump successively; The refrigerated medium pump outlet is connected with indoor set through pipeline, constitutes the kind of refrigeration cycle of a sealing thus.
In a preferred embodiment of the utility model, be the enhanced heat exchange effect, described evaporator bank and condenser group all can be provided with blower fan.Described reservoir and refrigerated medium pump are arranged in the rack.The liquid level discrepancy in elevation of described reservoir and refrigerated medium pump import keeps certain static pressure pressure head.
Compared with prior art, the energy-saving air conditioning system of the utility model design adopts refrigerated medium pump as power, and the evaporator bank parallel connection is provided with, and flow is bigger, good refrigeration effect, and heat exchange efficiency is high and simple in structure.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the energy-saving air conditioning system that the utility model proposes is made up of indoor set 3, outdoor condenser group 5 and outdoor pump cabinet 8, and each parts connects through pipeline.Indoor set 3 is composed in parallel by one or more evaporimeters, and magnetic valve 2 is installed on the feed tube of each evaporimeter.Condenser group 5 is composed in parallel by one or more condensers 6, connects through tube connector 4 between indoor set 3 and the outdoor condenser group 5.Comprise reservoir 7 and refrigerated medium pump 9 in the outdoor pump cabinet 8, connect through tube connector 10 between condenser group 5 and the outdoor pump cabinet 8.Connect through tube connector 11 between outdoor pump cabinet 8 and the indoor set 3.Whole refrigeration system provides power by refrigerated medium pump 9, and constitutes the kind of refrigeration cycle of a sealing.
The utility model can be used with the computer-room air conditioning system that adopts compressor.Indoor set 3 can be directly installed on original air conditioner in machine room, does not need to dispose breeze fan again.The utility model also can independent operating, is the enhanced heat exchange effect, all configurable independently breeze fan of evaporimeter and condenser.
The utility model can automatically switch into energy-saving run that utilizes natural cooling source or the compressor operating that utilizes former air conditioner in machine room according to factors such as heat load sizes in the indoor and outdoor surroundings temperature difference, the machine room, to reach refrigeration system operation optimum operation efficiency.
At outdoor environment temperature higher or indoor/outdoor temperature-difference less in, the energy-saving air conditioning system of the utility model design is out of service, refrigerated medium pump 9 is shut down, evaporator bank magnetic valve 2 cuts out.Open former air conditioner in machine room compressor assembly operation, for data center provides cold.
When the low perhaps indoor/outdoor temperature-difference of outdoor environment temperature is bigger, the energy-saving air conditioning system operation of the utility model design, refrigerated medium pump 9 starts, evaporimeter magnetic valve 2 is opened, and former air conditioner in machine room compressor assembly is out of service.Energy-saving type air conditioner refrigeration system circulating path is: refrigerated medium pump 9->tube connector 11->magnetic valve 2->evaporimeter 1->tube connector 4->condenser 6->tube connector 10->reservoir 7->refrigerated medium pump 9, accomplish a circulation.In refrigerated medium pump 9 operations, will store certain refrigerant liquid all the time in the reservoir 7, because the liquid level discrepancy in elevation of reservoir 7 and refrigerated medium pump 9 imports provides certain static pressure pressure head, cavitation can not appear in the time of can guaranteeing pump operation.The height of reservoir must be considered net positive suction head NPSH and the reservoir of pump itself resistance to pipeline between pump inlet.The blower fan of outdoor condenser group 5 can speed governing operation, is not less than the dew-point temperature of return air in the data center with the fluid temperature that guarantees condensator outlet, guarantees that energy-conservation unit realizes the full sensible heat operation of evaporated condensation water.
The utility model can be realized air conditioner in machine room types such as air-cooled, water-cooled, chilled water are carried out reducing energy consumption.Because indoor machine evaporation has adopted many modes, can realize big flow operation, the operating point that makes pump is more near best efficiency point; And many indoor machine evaporations can only dispose a refrigerated medium pump, move more energy-conservation.Indoor machine evaporation can be installed on original air conditioner in machine room; The structure of original air-conditioning is not carried out big change; Guaranteed original air conditioner in machine room reliability of operation and stability, the blower fan system of original air conditioner in machine room capable of using is blown, and makes compact conformation; Do not take the ground space of data center, and on-the-spot easy for installation.In addition, through refrigerant liquid temperature is controlled, realize 100% sensible heat of indoor machine evaporation operation, evaporated condensation water has been realized energy-saving run, has also improved the security of unit operation simultaneously.
