Make actually detected to running current reach to limit accordingly frequency protective current, the running current detected the most when cooling is more than
The most directly shut down during refrigeration stoppage protection electric current, the running current detected when heating more than when heating stoppage protection electric current then
Directly shut down.
Specifically, during refrigeration, the interval and corresponding corresponding relation limiting protective current frequently of multiple outdoor temperatures can institute as follows
Showing: as T4 ＞ 50.5 DEG C, limit frequency protective current is CL5；As 49.5 DEG C >=T4 ＞ 45.5 DEG C, limit frequency protective current is CL4；
As 44.5 DEG C >=T4 ＞ 41 DEG C, limit frequency protective current is CL3；As 40 DEG C >=T4 ＞ 33 DEG C, limit frequency protective current is CL2；When
32 >=T4 DEG C, limit frequency protective current is CL1.Wherein CL5, CL4, CL3, CL2, CL1 and the concrete number of refrigeration stoppage protection electric current
Value specifically can limit according to practical situation, does not limits at this.
The outdoor environment temperature T4 such as detected when refrigerating operaton is positioned at the interval 40 DEG C >=T4 ＞ 33 DEG C of outdoor temperature
Time interior, then it represents that running current does not allow more than limit frequency protective current CL2, if it does, running current will be downconverted to less than limit
Frequently protective current CL2.
When heating, the corresponding relation of multiple outdoor temperatures interval and corresponding limit frequency protective current can be as follows: works as T4
During ＞ 15 DEG C, limit frequency protective current is HL5；When 14 DEG C of ＞ T4 >=10 DEG C, limit frequency protective current is HL4；When 9 DEG C of ＞ T4 >=6
DEG C time, limit frequency protective current be HL3；When 5 DEG C of ＞ T4 >=-19 DEG C, limit frequency protective current is HL2；As-20 DEG C of ＞ T4, limit frequency is protected
Protecting electric current is HL1.Wherein HL5, HL4, HL3, HL2, HL1 and heat the concrete numerical value of stoppage protection electric current can be according to actual feelings
Condition specifically limits, and does not limits at this.
Such as when the outdoor environment temperature T4 detected when heating operation is positioned at outdoor temperature interval 9 DEG C of ＞ T4 >=6 DEG C,
Then represent that running current does not allow more than limit frequency protective current HL3, if it does, running current will be downconverted to less than limit frequency protection
Electric current HL3.
In some embodiments of the invention, can preset multiple outdoor temperature interval, multiple outdoor temperature intervals are corresponding
Different setting running frequencies, according to the setting fortune that the outdoor temperature interval at the actually detected outdoor environment temperature place arrived is corresponding
Line frequency adjusts the running frequency of compressor.
In some embodiments of the invention, multiple different pressure at expulsion is first preset interval, multiple pressure at expulsion districts
Between the regulating command of corresponding running frequency different, then detection pressure at expulsion the row according to the pressure at expulsion place detected
The regulating command regulation running frequency that atmospheric pressure interval is corresponding.Wherein regulating command can include frequency reducing, raising frequency, holding frequency,
The instructions such as shutdown, releasing frequency limitation.Thus the running frequency of compressor is adjusted by detection pressure at expulsion, can be the most anti-
Answer the running status of system, it is ensured that system operates in suitable parameter area, improve air-conditioner reliability of operation further.
