The aperture on road.In the present embodiment, according to trigger signal is started, control valve 42 is turned on, control valve 41 and 43 is turned off, at this time in system
Unnecessary refrigerant is stored into reservoir 3 through control valve 42.In certain embodiments, other valves can also be configured as needed
Body, such as four-way valve 8, shut-off valve 91,92, check valve 93 etc..
The efficiency variable quantity of step S200, at preset timed intervals interval acquiring unit.In the present embodiment, prefixed time interval t1
It can rule of thumb determine, can also be obtained by theory analysis.For example：When 100% load operation of system, due to system
Differ smaller with the coolant quantity in system in the optimal coolant quantity needed for 100% load operation, therefore liquid storage and discharge opeing action every time
Required time is shorter, therefore prefixed time interval time t1 is 2min；When 50% load operation of system, since system is negative 50%
Optimal coolant quantity needed for lotus operation differ larger with the coolant quantity in system, thus every time liquid storage and discharge opeing act required time compared with
It is short, therefore prefixed time interval time t1 is 5min；When 25% load operation of system, since system is needed for 25% load operation
Optimal coolant quantity differs bigger with the coolant quantity in system, therefore shorter the time required to liquid storage and discharge opeing action every time, thus it is default when
Between interval time t1 be 10min.It should be noted that the concrete numerical value of above-mentioned example is it is not intended that form to present techniques
The restriction of scheme, simply gives a kind of exemplary enlightenment when those skilled in the art determine prefixed time interval t1.This implementation
In example, the efficiency variable quantity △ a, alleged efficiency variable quantity △ a that are spaced t1 acquisition units at preset timed intervals refer to current sampling point
Efficiency relative to a upper sampled point efficiency variable quantity.
Step S300, switch-over control signal is sent according to the size of efficiency variable quantity to control valve.In the present embodiment, by

Certainly, if efficiency variable quantity is less than preset value, sent to control valve and be used to characterize switching current pass state
Switching signal.Specifically, please refer to Fig.2, if detecting that efficiency variable quantity △ a are less than 0, represent that system energy efficiency reduces, then
Discharge opeing action is carried out, turns off control valve 42 at this time, turns on control valve 41 and 43, the gaseous coolant warp that 6 exhaust end of compressor comes out
Oil eliminator 7, control valve 41 flow to reservoir 3, by pressure by the refrigerant stored in reservoir 3 by reservoir bottom through control
Valve 42 drains into 6 suction side of compressor so that refrigerant circulation increase in system.
It should be noted that after current pass state is switched, interval acquiring unit at preset timed intervals can also continue to
Efficiency variable quantity △ a, if efficiency variable quantity △ a are more than or equal to 0, represent system energy efficiency increase, continue to keep current path
State；If efficiency variable quantity △ a are less than 0, represent that system energy efficiency reduces, then switch current channel status (such as discharge opeing)
For another channel status (such as liquid storage).That is, the path shape of liquid storage and discharge opeing is switched according to the size of efficiency variable quantity △ a
State.
In an alternate embodiment of the invention, after step S300 is performed, further include：
Step S400, judges whether the number of channel status switching cycle reaches preset times.It is alleged logical in the present embodiment
The cycle that line state switches is from reservoir stores coolant path conducting, is stopped to closing on when discharge coolant path turns off.That is,
It is a channel status from being stored during the storage coolant path conducting of this reservoir to reservoir next time when coolant path turns on
The cycle of switching.In a particular embodiment, judge whether the frequency n of channel status switching cycle is more than preset times m, if logical
The number of line state switching cycle reaches preset times (n ＞ m), then performs step S500；If channel status switching cycle
Number is not up to preset times, then continues to return to execution step S200, step S300 and step S400.
Step S500, the cut-off signals for being used for characterizing shut-off control valve are sent to control valve.Thus, reservoir storage is turned off
Coolant path and discharge coolant path.Specifically, control valve 41,42 and 43 is turned off, so as to complete the storage and discharge of refrigerant
The operation of adjusting so that coolant quantity levels off to the operation of optimal efficiency.
After the adjusting by above-mentioned steps, the coarse adjustment of system energy efficiency optimization operation is completed.It is to further improve
System efficiency, is finely adjusted system refrigerant circulation, in an alternate embodiment of the invention, after step S500 is performed, can also wrap
