Mechanical refrigeration evaporator/condenser cells D: by scroll compressor 25, air cooled condenser 26, choke valve 27 and Direct-expansion-type vaporizer 17 passes sequentially through copper pipe and connects and composes closed-loop path;Wherein, the condensation that air cooled condenser 26 produces Heat is taken away by control air, and direct-expansion-type vaporizer 17 can carry out dehumidification cooling to output air.
Fan unit E: be made up of secondary exhausting machine 28 and pressure fan 18;The secondary exhausting machine 28 secondary after processing Air is discharged, and pressure fan 18 is for sending into the cold wind meeting air-supply condition in data center through ajutage 2, machine room air outlet 3 Each bar cold air duct in, it is achieved to the cooling of Servers-all in server cabinet 4.
Data center of the present invention is as follows by the work process closing the passage of heat-full return air dry air energy central air conditioner system:
Under the dynamic action of pressure fan 18, in data center, the hot-air in all closing passage of heats 5 is through return air Pipe 8 is delivered in return air channel, then by return air channel and return air air inlet 9, hot-air is sent into dry air energy Central air-conditioning unit In lower air duct in 1;
By pocket type roughing efficiency air filter a10, hot-air is filtered, form clean hot-air;
By parts different in opening dry air energy Central air-conditioning unit 1, clean hot-air is located accordingly After reason, just can form the air meeting air-supply condition;
Under the effect of pressure fan 18, the air meeting air-supply condition is delivered to data through ajutage 2 and machine room air outlet 3 In intracardiac, meet the air of air-supply condition and in data center, fill the air the mode of air-supply enter in each bar cold air duct, then enter Enter in each server cabinet 4, for cooling down the server in server cabinet 4, after device to be serviced has cooled down, meet air-supply The air of condition, because absorbing the heat of server and temperature rising, becomes hot-air again;
Hot-air flows into be closed in the passage of heat 5, afterwards using this part hot-air as the return air in data center, return air warp Return air channel in data center's infantile tic top layer 6, backwind tube 8 enter in the lower air duct in dry air energy Central air-conditioning unit 1, and Circulation is completed with this.
Data center of the present invention can realize following three kinds of fortune with closing the passage of heat-full return air dry air energy central air conditioner system Row mode:
(1) coil pipe indirect evaporating-cooling and mechanical refrigeration combined operation approach (IEC+DX): this pattern is mainly for summer Operating mode, and the situation that data center's load is the biggest;To open directly-coil pipe indirect evaporating-cooling unit B in this operating mode With mechanical refrigeration evaporator/condenser cells D, concrete work process is as follows:
Under the dynamic action of pressure fan 18, the hot-air closed in the passage of heat 5 in data center enters through backwind tube 8 Enter in the lower air duct in dry air energy Central air-conditioning unit 1;Hot-air is formed clean after pocket type roughing efficiency air filter a10 filters Hot-air;Clean hot-air is clammy but through directly-coil pipe indirect evaporating-cooling unit B inner tube indirect evaporation cooler 11 etc., Enter in mechanical refrigeration evaporator/condenser cells D afterwards, direct-expansion-type vaporizer 17 it is further dropped Temperature;Finally under the effect of pressure fan 18, send into each bar cold air duct in data center through ajutage 2 and machine room air outlet 3 In, for cooling down the server in data center.
Outdoor air, under the effect of secondary exhausting machine 28, is entered dry air energy central air conditioning by secondary wind air inlet 20 In upper air duct in group 1;Outdoor air, after pocket type roughing efficiency air filter b21 filters, forms clean auxiliary air;Clean Auxiliary air enters in the first direct evaporating-cooling unit, with direct evaporating-cooling filler at direct evaporating-cooling filler b23 Moisture film generation hot and humid area on b23 surface (by water distribution unit by Water spray on direct evaporating-cooling filler b23, directly Evaporation cooling filler b23 surface forms moisture film), form secondary cold wind;Secondary cold wind blows to air cooled condenser 26, lowers the temperature for it Heat radiation;The air finally absorbing condensation heat is discharged to outdoor through secondary wind exhaust outlet 29 under the effect of secondary exhausting machine 28.
(2) coil pipe indirect evaporating-cooling and direct evaporating-cooling combined operation approach (IDEC): this pattern is mainly for mistake Cross season, and data center's internal heat generation amount is less, in the case of needing again necessarily to humidify simultaneously;Mainly open under this operational mode Directly-coil pipe indirect evaporating-cooling unit B and the second direct evaporating-cooling unit, specific works process is as follows:
Under the dynamic action of pressure fan 18, the hot-air closed in the passage of heat 5 in data center enters through backwind tube 8 Enter in the lower air duct in dry air energy Central air-conditioning unit 1;Hot-air is formed clean after pocket type roughing efficiency air filter a10 filters Hot-air;Clean hot-air is clammy through directly-coil pipe indirect evaporating-cooling unit B inner coil pipe indirect evaporation cooler 11 etc. But, in entering the second direct evaporating-cooling unit afterwards, carry out constant enthalpy cooling, form the air meeting air-supply condition;Finally, symbol The air closing air-supply condition sends into each bar in data center through ajutage 2 and machine room air outlet 3 under the effect of pressure fan 18 In cold air duct, for cooling down each server in data center.
Outdoor air, under the effect of secondary exhausting machine 28, is entered dry air energy central air conditioning by secondary wind air inlet 20 In upper air duct in group 1;Outdoor air forms the auxiliary air of cleaning after pocket type roughing efficiency air filter b21 filters;Clean two Secondary air enters in the first direct evaporating-cooling unit, with direct evaporating-cooling filler b23 at direct evaporating-cooling filler b23 Moisture film generation hot and humid area on surface (by water distribution unit by Water spray on direct evaporating-cooling filler b23, at direct evaporation Cooling filler b23 surface forms moisture film), form secondary cold wind;Secondary cold wind blows to air cooled condenser 26, dissipates for its cooling Heat;The air finally absorbing condensation heat is discharged to outdoor through secondary wind exhaust outlet 29 under the effect of secondary exhausting machine 28.
(3) direct evaporating-cooling (DEC) operational mode: mainly for transition season, and the feelings that data center's caloric value is little Under condition, lower of this operational mode need to open the second direct evaporating-cooling unit, and specific works process is as follows:
Under the dynamic action of pressure fan 18, the hot-air closed in the passage of heat 5 in data center enters through backwind tube 8 Enter in the lower air duct in dry air energy Central air-conditioning unit 1;Hot-air, after pocket type roughing efficiency air filter a10 filters, forms cleaning Hot-air;Clean hot-air enters in the second direct evaporating-cooling unit, by the second direct evaporating-cooling unit to cleaning Hot-air carry out constant enthalpy cooling process, form the air meeting air-supply condition;Meet the air of air-supply condition in pressure fan 18 Effect under in ajutage 2 and machine room air outlet 3 send into the cold passage of each bar in data center, be used for cooling down in data center Each server.
Mainly there is following two work in data center of the present invention with closing the passage of heat-full return air dry air energy central air conditioner system Make cyclic process:
(1) mechanical refrigeration cycle of operation, detailed process is as follows:
