Specifically, system is introduced into original state after system electrification, stable operation is at the first time in the initial state
Duan Hou, into stable state.
Original state refers to that the temperature difference between outside condensation temperature and outside environment temperature is fiducial temperature value.Its
In, outside condensation temperature refers to the temperature of outside tube temperature temperature sensing package.
Fiducial temperature value is empirical value or the value that experiment obtains.Such as: the fiducial temperature value is 4 DEG C.
First time period is empirical value or the value that experiment obtains.Such as: first time period 30min.
Such as: when monitoring the temperature difference between outside condensation temperature and outside environment temperature is 4 DEG C, determine system
Into original state, then system stable operation 30min, the parameter of system all tend towards stability, and it is steady to determine that system enters at this time
Determine state, adjusts outer rotation speed of fan, monitoring Energy Efficiency Ratio variation later.
During adjusting outer rotation speed of fan, the time span of control interval is equal or different, and control interval can be with

Wherein, E is Energy Efficiency Ratio, and M is mass of system flow, and H1 is inlet side enthalpy on the inside of system chambers, and H2 is in system chambers
Side air-out side enthalpy, M (H2-H1) indicate cooling system amount, and P is always system consumption power.M can be obtained according to Wind Coverage Calculation.
If the consumption power of other devices except outer blower consumption power and compressor consumption power can be ignored, such as
The consumption power of electric controller etc. is negligible, efficiency specific power can be adjusted are as follows:
E=M (H2-H1)/(P wind+P pressure)；
Wherein, P wind is that outer blower consumes power, and P pressure is that compressor consumes power.
Step S130 will be described when positive and negative variation occurs in the Energy Efficiency Ratio variable quantity for monitoring two neighboring control interval
Outer blower stabilization of speed is on the corresponding revolving speed of previous control interval.
In the present embodiment, it when positive and negative variation occurs in the Energy Efficiency Ratio variable quantity for monitoring two neighboring control interval, says
The Energy Efficiency Ratio of bright system has reached peak value, and the Energy Efficiency Ratio of system is optimal, the revolving speed of at this moment stable outer blower, the Energy Efficiency Ratio of system

90%.Further, since system electrification, outer rotation speed of fan is constantly tuned up, if in outer rotation speed of fan from first
During revolving speed is gone to second, monitor that outside condensation temperature is equal to outside environment temperature and adds fiducial temperature value,
Then determine that system is further continued for after operation first time period, into stable state.

If the outer rotation speed of fan is increased preset rotation speed value in current control interval, and the control interval originates
The Energy Efficiency Ratio at moment is more than or equal to the Energy Efficiency Ratio of end time, then reduces the outer rotation speed of fan in next control interval pre-
If tachometer value.
The outer rotation speed of fan is improved preset rotation speed value, until the exogenous wind in next control interval by step S330
Until machine consumes power variation more than or equal to compressor consumption power variation.
It can come temporarily in next control interval, the outer rotation speed of fan be improved into preset rotation speed value, until described outer
Until blower consumes power variation more than or equal to compressor consumption power variation.
Outer blower consumption power variation is less than compressor and consumes power variation, and the overall refrigerating effect of system increases, always disappears
Wasted work rate reduces, and the real-time revolving speed of outer blower can continue to increase at this time.
The present embodiment changes systematic energy efficiency ratio by adjusting outer rotation speed of fan, and the efficiency for monitoring system changes, and according to
