Wherein the concrete numerical value of CL5, CL4, CL3, CL2, CL1 and refrigeration stoppage protection electric current can be according to reality
Situation specifically limits, and 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 of outdoor temperature
Time in ＞ 33 DEG C, then it represents that running current does not allow more than limit frequency protective current CL2, if it does, will fall
Frequency to running current is less than limit frequency protective current CL2.
When heating, the interval and corresponding corresponding relation limiting protective current frequently of multiple outdoor temperatures can institute as follows
Showing: as T4 ＞ 15 DEG C, limit frequency protective current is HL5；When 14 DEG C of ＞ T4 >=10 DEG C, limit frequency protection
Electric current is HL4；When 9 DEG C of ＞ T4 >=6 DEG C, limit frequency protective current is HL3；When 5 DEG C of ＞ T4 >=-19 DEG C,
Limit frequency protective current is HL2；As-20 DEG C of ＞ T4, limit frequency protective current is HL1.Wherein HL5, HL4,
HL3, HL2, HL1 and heat the concrete numerical value of stoppage protection electric current and specifically can limit according to practical situation,
Do not limit at this.
The outdoor environment temperature T4 such as detected when heating operation is positioned at the interval 9 DEG C of ＞ T4 of outdoor temperature
When >=6 DEG C, then it represents that running current does not allow more than limit frequency protective current HL3, if it does, by frequency reducing
To running current less than limit frequency protective current HL3.
In embodiments more of the present utility model, multiple outdoor temperature can be preset interval, multiple outdoor temps
The interval corresponding different setting running frequency of degree, according to the outdoor at the actually detected outdoor environment temperature place arrived
The running frequency of the setting running frequency adjustment compressor that temperature range is corresponding.
In embodiments more of the present utility model, first preset multiple different pressure at expulsion interval, multiple
The regulating command of the running frequency that pressure at expulsion interval is corresponding is different, then detects pressure at expulsion and according to detection
The regulating command that the pressure at expulsion interval at the pressure at expulsion place arrived is corresponding regulates running frequency.Wherein regulation refers to
Order can include frequency reducing, raising frequency, holding frequency, shut down, releases the instruction such as frequency limitation.Thus by inspection
Survey pressure at expulsion and adjust the running frequency of compressor, can the running status of direct response system, it is ensured that be
System operates in suitable parameter area, improves air-conditioner reliability of operation further.
