A kind of energy-saving air-conditioning device
Technical field
The utility model relates to aircondition, especially relates to a kind of energy-saving air-conditioning device that is used for the server rack heat radiation.
Background technology
Increase along with data center's machine; Its heat density rises year by year; The a large amount of new frame formula servers that adopt and the heat density of blade server have reached the 20-30kW/ rack in the data center, and air-conditioning system commonly used has been difficult to satisfy the cooling requirement of the machine room of the high heat density of this type.Existing part machine room adopts chilled water backboard cooling technology, promptly near the service rack air side, backboard is installed, and this backboard adopts coil exchanger, and cooling medium is a cryogenic freezing water.Not enough below this chilled water backplane technology exists:
1. there is the accidental water leakage risk.The water-cooled backboard is brought water near the server rack into, in case earthquake occurs or other contingencies cause leaking, consequence is very serious;
2. the condensation phenomenon appears easily.If the chilled water temperature that air conditioner facility provides is lower than the dew-point temperature of water-cooled backboard air intake, can produce condensate on the backboard;
3. there is the water hammer risk.Because the water-cooled backboard spreads all over whole data communication center, so can use the special-purpose water valve of many frames.Any one irregular working in these valves possibly cause water hammer in whole system, cause cooling system to be destroyed;
4. water quality is prone to worsen.The factor that influences water quality has a lot, and comprising presenting solid suspension, germ contamination and inappropriate pH value, water quality deterioration can cause radiating effect decline, equipment fault.
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 device.
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 device of design; Comprise indoor set and off-premises station, connect that wherein: described indoor set comprises that at least one is installed in the cooling backboard of server rack air side through pipeline; Described off-premises station is made up of the air cooling heat exchanger and the chilled water heat exchanger of parallel connection, and described air cooling heat exchanger and chilled water heat exchanger inlet end are provided with magnetic valve.
In an embodiment of the utility model, described air cooling heat exchanger adopts condenser coil and is provided with the blower fan of adjustable speed.Described indoor set comprises that at least one is installed in the cooling backboard of server rack air side, and the cooling backboard adopts evaporation coil.Described chilled water heat exchanger is provided with the triple valve of regulating pondage.
The utility model uses cold-producing medium and thermosiphon principle, for server rack provides cooling nearby, and the heat dissipation problem of settlement server frame; The leakage accident of having avoided server rack to occur; Also can select to use natural cooling source or handpiece Water Chilling Units, practice thrift energy consumption significantly, reduce operating cost according to the variation of weather.
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 device that the utility model proposes comprises: indoor set 1 and the off-premises station that is composed in parallel by air cooling heat exchanger 6 and chilled water heat exchanger 9, indoor set is connected through pipeline with off-premises station.Indoor set 1 comprises that at least one is installed in the cooling backboard 3 of server rack air side, and cooling backboard 3 adopts evaporator coil.Very little owing to falling through the air pressure of cooling backboard 3, can directly utilize the blower fan of server rack to obtain necessary air circulation flow.Air cooling heat exchanger 6 adopts condenser coil and is provided with the blower fan of adjustable speed.Chilled water heat exchanger 9 provides cold by the handpiece Water Chilling Units kind of refrigeration cycle.The evaporator coil top of cooling backboard 3 is through the condenser coil in steam pipe 4 and the air cooling heat exchanger 6; Or the condenser coil top in the chilled water heat exchanger 9 connects; The inlet end of air cooling heat exchanger 6 and chilled water heat exchanger 9 is respectively equipped with magnetic valve 7 and 8, is used for the switching between air cooling heat exchanger 6 and the chilled water heat exchanger 9.The condenser coil bottom of air cooling heat exchanger 6 and the condenser coil bottom of chilled water heat exchanger 9 are connected with the evaporator coil bottom of cooling backboard 3 through woven hose 5.The condenser coil of the evaporator coil of cooling backboard 3 and the condenser coil of air cooling heat exchanger 6 and chilled water heat exchanger 9 forms the space of sealing through steam pipe 4 and woven hose 5, and fills a certain amount of cold-producing medium working medium.
During work, when outdoor temperature is lower than indoor temperature and a fixed difference difference is arranged, close magnetic valve 8; Open magnetic valve 7; Cooling backboard 3 absorbs the heat that server rack 2 is discharged, and cools off the cold-producing medium working medium vaporization of backboard 3 inside, rises to the condenser coil top of air cooling heat exchanger 6 through steam pipe 4.Cold-producing medium working medium is dispelled the heat with the atmospheric environment heat exchange in the condenser coil of air cooling heat exchanger 6, and condensation of refrigerant becomes liquid, flows back to the evaporator coil bottom of cooling backboard 3 then through woven hose 5.The condenser fan of air cooling heat exchanger 6 can carry out speed governing operation according to outdoor temperature, is not less than server rack air-out dew-point temperature with control woven hose fluid temperature, realizes the full sensible heat operation of evaporated condensation water.When having a fixed difference difference, the utility model can utilize natural cooling source, endlessly the heat of server rack is dispersed into outdoorly, reaches the effect of good heat radiation.
When less or outdoor temperature is higher than indoor temperature when indoor/outdoor temperature-difference; Close magnetic valve 7, open magnetic valve 8, cooling backboard 3 absorbs the heat that server rack 2 is discharged; Make its inner cold-producing medium working medium vaporization, rise to the condenser coil top in the chilled water heat exchanger 9 through steam pipe 4.Cold-producing medium working medium is carried out heat exchange through the chilled water that provides with handpiece Water Chilling Units in chilled water heat exchanger 9, condensation of refrigerant becomes liquid, flows back to the evaporator coil bottom of cooling backboard 3 then through woven hose 5.Chilled water heat exchanger 9 can be regulated chilled-water flow through triple valve 10, is not less than server rack air-out dew-point temperature with control woven hose fluid temperature, realizes the full sensible heat operation of evaporated condensation water.When indoor/outdoor temperature-difference hour, the low-temperature receiver that the utility model can utilize handpiece Water Chilling Units to provide, the heat transferred chilled water with server rack reaches the heat radiation purpose.
Common precise machine room air conditioner compressor refrigeration system Energy Efficiency Ratio generally can only accomplish 2.5~3.5.The energy-saving air-conditioning device that the utility model proposes can realize utilizing natural cooling source when outdoor temperature is lower, need not utilize compressor that power is provided, and Energy Efficiency Ratio can reach more than 10; When outdoor temperature was higher, the chilled water that high efficiency handpiece Water Chilling Units capable of using provides was as low-temperature receiver, and Energy Efficiency Ratio can reach 3.5~4.5, still is higher than general precise machine room air conditioner, and energy-saving effect is obvious, can significantly reduce user's operating cost.
