Step S12, according to the corresponding pass between default outdoor environment temperature with running frequency, target temperature System, determines running frequency corresponding to described current outdoor ambient temperature and target temperature；

Optionally, described corresponding relation is default outdoor environment temperature interval and running frequency, target temperature Corresponding relation between degree.Such as, as shown in table 1, table 1 shows an outdoor environment temperature preset Corresponding relation between region and running frequency, target temperature.

Table 1

Outdoor environment temperature is interval (DEG C)	Running frequency (Hz)	Target temperature (DEG C)
			T≥30℃	80Hz	10℃
20℃≤T<30℃	90Hz	6℃
			T<20℃	70Hz	0℃

When determining running frequency corresponding to current outdoor ambient temperature and target temperature, first determine and work as cup The outdoor environment temperature at external environment temperature place is interval, determines the operation frequency that this temperature range is corresponding the most again Rate and target temperature, i.e. according to default outdoor environment temperature interval with running frequency, target temperature it Between corresponding relation, by running frequency corresponding for the described outdoor environment temperature interval that determines, target temperature It is defined as running frequency corresponding to described current outdoor ambient temperature and target temperature.For example, it is assumed that it is current Outdoor environment temperature is 25 DEG C, then the running frequency that current outdoor ambient temperature is corresponding is 90Hz, target temperature Degree is 6 DEG C.Assume that current outdoor ambient temperature is 18 DEG C, then the operation that current outdoor ambient temperature is corresponding Frequency is 70Hz, and target temperature is 0 DEG C.
