Under the action of difference, be connected between the high pressure admission mouth and exhaust outlet of triple valve 524；Meanwhile bypass solenoid valve 513 is closed, compression
Machine 523, condenser 525, electric expansion valve 512, evaporator 514 and gas-liquid separator 522 constitute steam compression type refrigeration circulation
Circuit；Under active refrigeration mode, refrigerant enters gas by gas side conduit 53 in 514 interior suction thermal evaporation of evaporator, gaseous coolant
Liquid/gas separator 522, gas-liquid separator 522 are filtered to by the liquid parts in air-flow, reduce the gas for entering compressor 523
The liquid parts of stream prevent compressor 523 from returning liquid and liquid hit phenomenon occur；Gaseous coolant is in high temperature after the compression of compressor 523

Logical dynamic distance between sub- expansion valve 512 and evaporator 514, to reduce liquid refrigerants in the loss of refrigeration capacity of the process of circulation.
When room temperature can meet the high efficiency heat absorption evaporation conditions of refrigerant, and indoor/outdoor temperature-difference is larger, Temperature fall can
When providing enough cooling effects, compressor 523 is out of service, between the high pressure admission mouth and low-pressure admission mouth of triple valve 524
Pressure differential collapses, under the action of the contained spring part of triple valve 524, between the low-pressure admission mouth and exhaust outlet of triple valve 524
Conducting, compressor 523 are short-circuited；Meanwhile bypass solenoid valve 513 is opened, under the effect of gravity, liquid refrigerants is largely gathered in place
In the evaporator 514 of low level, since evaporator 514 is in environment under low pressure, at normal temperature, the liquid in evaporator 514 is cold
Matchmaker is absorbed heat with certain rate and is evaporated, and gaseous refrigerant pressure difference is driven through outer bypass manifold 527 and triple valve 524 rises to
Condenser 525；The outdoor environment temperature as locating for condenser 525 is lower, and the relatively relatively high gaseous coolant of temperature is cold
The heat being absorbed into from evaporator 514 is discharged into the exterior space by condensation heat in condenser 525；It is condensed in condenser 525
The liquid refrigerants formed after heat release under the effect of gravity, is flowed back by fluid reservoir 526, liquid side conduit 54 and internal bypass conduit 516
To evaporator 514, a Temperature fall circulation is completed；As long as outdoor temperature is sufficiently low, indoor/outdoor temperature-difference is maintained at a range
Interior, the Temperature fall circulation of refrigerant just persistently carries out, and continues the heat transfer near evaporator 514 to 525 outside of condenser.
Referring to Fig. 3, specifically, room temperature locating for the main cabinet 20 of high energy efficiency single cabinet data center 10 is IRT；Room
Outdoor temperature locating for outer thermomechanical components 52 is ORT；The opening temperature of Temperature fall mode is RGT；The starting of Temperature fall mode
The temperature difference is △ T1, and △ T1=(IRT-ORT)；The unlatching temperature difference of active refrigeration mode is △ T2；The control of active refrigeration mode
Return difference is △ T3；The control return difference of Temperature fall mode is △ T4.
The operation switching mode of rack composite air conditioner 50 is as follows:
As IRT >=RGT and T1 >=5 DEG C △, Temperature fall mode operation；
When 5 DEG C of < of △ T4 DEG C or △ T1 of IRT < RGT-, Temperature fall mode is closed；
As IRT >=RGT+ △ T2, it is switched to braking refrigeration mode operation；
As IRT < RGT+ △ T2- △ T3, active refrigeration mode is closed.
Specifically, to ensure under Temperature fall mode, liquid refrigerants in evaporator 514 can effective evaporation endothermic, setting
RGT is 22 DEG C；When outdoor temperature reduce, when such as ORT=5 DEG C, at this time if room temperature IRT be 25 DEG C, IRT >=RGT and
T1=IRT-ORT >=5 DEG C △, the starting of Temperature fall mode, close compressor 523, the pressure differential collapses of 524 liang of inlet pipes of triple valve,
Under itself internal acting force of the spring, loop switch to outer bypass manifold 527, while bypass solenoid valve 513 is connected, liquid refrigerants
Passed through by bypass solenoid valve 513, the coolant quantity as needed for active refrigeration mode and Temperature fall mode differs greatly, Temperature fall
Mode needs coolant quantity more, by designing fluid reservoir 526 at condensate outlet, the adjustment of coolant quantity can be carried out, with adaline
Efficient operation demand of the posture composite air conditioner in active refrigeration mode and Temperature fall mode.
Under Temperature fall mode, liquid refrigerants is largely gathered in the evaporator 514 of low level machine, inside unit
Pressure is lower, and since room temperature is greater than 22 DEG C, the liquid refrigerants in evaporator 514 can be absorbed heat with certain rate and be evaporated,
The driving of gaseous coolant pressure difference rises to condenser 525.The outdoor environment temperature as locating for condenser 525 is relatively lower than 5 DEG C,
The relatively high gaseous coolant of temperature condenses heat release at condenser 525, and the heat absorbed from evaporator 514 is discharged into outdoor
Space, liquid refrigerants then flow back into evaporator 514 under the effect of gravity, complete a heat pipe Natural Circulation.As long as outdoor temperature
Sufficiently low, indoor/outdoor temperature-difference is maintained within the scope of 5 DEG C, and the Natural Circulation of refrigerant will continue to carry out, in a steady stream not by indoor heat
Disconnected reaches outdoor.At this point, the energy consumption component of entire rack composite air conditioner 50 is only indoor fan 515 and condensation fan
528, since compressor 523 does not put into operation, the input power of Temperature fall mode reduces one greatly compared to active refrigeration mode
Half.On the other hand, when outdoor temperature is lower, the heat dissipation capacity of Temperature fall is bigger, and indoor load is smaller, reduces room at this time
The revolving speed of inner blower 515 and condensation fan 528 can also meet cooling and require, so that the energy consumption of rack composite air conditioner 50
It is reduced, further enhances the energy-saving potential of Temperature fall mode.
Preferably, the unlatching temperature difference △ T2 of active refrigeration mode is 2 DEG C.
When outdoor temperature ORT is increased to 22 DEG C, IRT >=RGT but T1=IRT-ORT≤5 DEG C △, Temperature fall mode at this time
Do not start, IRT continues to increase, and as IRT >=RGT+ △ T2, when being 24 DEG C, opens compressor 523, triple valve 524 is in compressor
Active refrigeration mode is switched under the promotion of 523 suction draught heads, bypass solenoid valve 513 is closed, and refrigerant passes through electric expansion valve
Enter evaporator 514 after 512 throttlings to absorb heat, at low-temp low-pressure gaseous state after refrigerant heat absorption evaporation, go out to prevent compressor 523 from returning liquid
Existing liquid hammer increases gas-liquid separator 522 in design before compressor 523 and guarantees that entering compressor 523 is gaseous coolant, and gaseous state is cold
Matchmaker, at the gaseous coolant of high temperature and pressure, condense with after outdoor air heat exchange into condenser 525 after the compression of compressor 523
At liquid refrigerants, liquid refrigerants is again introduced into electric expansion valve 512 along liquid side conduit 54 and throttles, and is thusly-formed active refrigeration and follows
Ring.
When room temperature IRT rises, preferential unlatching Temperature fall mode in the ungratified situation of indoor/outdoor temperature-difference, is led
Cause IRT continue to rise later, arrive IRT >=RGT+ △ T2 when after, active refrigeration mode open, make IRT temperature in set temperature model
In enclosing.If indoor/outdoor temperature-difference is met more than or equal to 5 DEG C, Temperature fall mode is opened, and IRT temperature is stablized in setting range
It is interior, at this time as increase by 40 load of IT module, cause IRT to continue to rise later, arrive IRT >=RGT+ △ T2 when after, active refrigeration mould
Formula is opened.When IRT temperature reduces, preferential closing active refrigeration mode further decreases the indoor wind of Temperature fall cycle of modes
The revolving speed of machine 515 and condensation fan 528, until closing.
