When border temperature is less than three temperature thresholds higher than the second temperature threshold but outdoor environment temperature, the outer mainboard of control room obtains electric, protects
Card compressor reliably can start when being in low temperature environment after receiving enabled instruction, when outdoor environment temperature is higher than the 3rd temperature
During degree threshold value, illustrate without compressor housing being carried out heat treated, therefore the outer mainboard power-off of control room, thus reduce air-conditioning
Stand-by power consumption.
Above it is stated that the specified time interval obtaining indoor environment temperature can be definite value can also be variate.
In enforcement, this specified time interval can be determined according to indoor environment temperature, when indoor environment temperature is higher, when this is specific
Between interval could be arranged to bigger numerical value, when indoor environment temperature is relatively low, this specified time interval could be arranged to less
Numerical value.
The specified time interval that twice obtains between indoor environment temperature can determine according in the following manner:
Determine the indoor environment temperature that the last time gets；
According to the corresponding relation of indoor environment temperature Yu time interval, determine the indoor environment temperature that the last time gets
Corresponding time interval, using the time interval that gets as specified time interval；
Wherein, in the indoor environment temperature corresponding relation with time interval, time interval is along with indoor environment temperature

Seeing Fig. 2, Fig. 2 is a kind of flow chart obtaining indoor environment temperature in Fig. 1 according to specified time interval.Including:
Step S101: determine the indoor environment temperature that the last time gets.
Step S102: according to the corresponding relation of indoor environment temperature Yu time interval, determines the room that the last time gets
Time interval corresponding to interior ambient temperature.
The corresponding relation of indoor environment temperature and time interval is prestored, in this correspondence in the power supply control apparatus of air-conditioning
In relation, time interval increases along with the rising of indoor environment temperature.
Step S103: when the closest time once obtaining indoor environment temperature reaches this time interval, again obtain
Take indoor environment temperature.
After execution once obtains the operation of indoor environment temperature, reach step S102 when the time apart from this operation
After the time interval determined, again perform to obtain the operation of indoor environment temperature.
Outside air temperature is as the passage of time and changes, and whole temperature Change is relatively slow process.According to Fig. 2
Shown method, when indoor environment temperature is relatively low, performs to obtain the operation of indoor environment temperature with less time interval, when
When indoor environment temperature is higher, perform to obtain the operation of indoor environment temperature with bigger time interval.So on the one hand, permissible
Ensure when temperature is relatively low in time to off-premises station main board power supply, on the other hand can also reduce power supply control apparatus and perform to obtain room
Interior ambient temperature and the number of times of follow-up flow process, thus reduce workload and the power consumption of power supply control apparatus.
See the flow chart of the method for controlling power supply that Fig. 3, Fig. 3 are another kind of air-conditioning disclosed by the invention.This power supply control
Method includes:
Step S1: when air-conditioning is in holding state, obtains indoor environment temperature according to specified time interval and stores.
Step S2: after every time obtaining indoor environment temperature, compares indoor environment temperature and the first temperature threshold and the
Two temperature thresholds, when indoor environment temperature is less than the first temperature threshold, perform step S3, when indoor environment temperature is higher than second
During temperature threshold, perform step S4.
Step S3: the off-premises station mainboard controlling air-conditioning obtains electric.
Step S4: the outer mainboard of control room obtains electric, obtains outdoor environment temperature and stores.
Step S5: compare outdoor environment temperature and the 3rd temperature threshold, when outdoor environment temperature is less than the 3rd temperature threshold
Time, perform step S6, otherwise perform step S7.
Step S6: the outer mainboard of control room continues electric.
Step S7: the outer mainboard power-off of control room, performs step S8.
Step S8: wait special time, perform step S4 afterwards.
Compared with method shown in Fig. 1, in method shown in Fig. 3, power supply control apparatus after the outer mainboard power-off of control room, etc.
Treat special time, the most again perform the outer mainboard of control room and obtain electric, obtain the step of outdoor environment temperature.
Preset Time in step s 8 can be definite value, can also adopt and determine in other ways in enforcement.Below in conjunction with
Fig. 4 and Fig. 5 illustrates.
Seeing Fig. 4, Fig. 4 is a kind of flow chart determining the waiting time in the present invention.Including:
Step S801: determine the outdoor environment temperature that the last time gets.
Step S802: according to the corresponding relation of outdoor environment temperature Yu time value, determines the outdoor that the last time gets
Time value corresponding to ambient temperature, using this time value as special time.
Wherein, in the outdoor environment temperature corresponding relation with time value, time value is along with the rising of outdoor environment temperature
And increase.Outdoor environment temperature is as shown in table 1 with a kind of corresponding relation of time value.In Table 1, T outer shroud represents outdoor environment
Temperature.

| Outdoor environment temperature | Time value |
| T outer shroud >=30 DEG C | 24h |
| 30 DEG C of ＞ T outer shroud >=20 DEG C | 16h |
| 20 DEG C of ＞ T outer shroud >=10 DEG C | 8h |
| 10 DEG C of ＞ T outer shroud >=5 DEG C | 4h |
| 5 DEG C of ＞ T outer shrouds | 0h |
According to the method shown in Fig. 4, when outdoor environment temperature is relatively low, is set as less time value the waiting time,
Power supply control apparatus performs the outer mainboard of control room with less time interval and obtains operation that is electric and that obtain outdoor environment temperature, when
When outdoor environment temperature is higher, being set as bigger time value the waiting time, power supply control apparatus is with bigger time interval
Perform the outer mainboard of control room and obtain operation that is electric and that obtain indoor environment temperature.The most both can ensure that when temperature is relatively low timely
To off-premises station main board power supply, the outer mainboard of control room can be reduced again and obtain electric number of times, thus reduce air-conditioning in the standby state
Power consumption.
Seeing Fig. 5, Fig. 5 is the another kind of flow chart determining the waiting time in the present invention.Including:
Step S811: judge whether to be only performed once the operation obtaining outdoor environment temperature, the most then perform step
S812, otherwise performs step S814.
If performing to obtain the operation of outdoor environment temperature for the first time, then the power supply control apparatus of air-conditioning only stores
There is an outdoor environment temperature value, if not performing to obtain the operation of outdoor environment temperature for the first time, then the power supply of air-conditioning
Control storage in device and have multiple outdoor environment temperature value.
Step S812: determine the outdoor environment temperature that the last time gets.
Step S813: according to the corresponding relation of outdoor environment temperature Yu time value, determines the outdoor that the last time gets
Time value corresponding to ambient temperature, using this time value as special time.
In the outdoor environment temperature corresponding relation with time value, time value increases along with the rising of outdoor environment temperature
Greatly, it would however also be possible to employ the corresponding relation shown in table 1.
After the operation performing acquisition outdoor environment temperature for the first time, when determining that outdoor environment temperature is greater than or equal to the 3rd
During temperature threshold, the outer mainboard power-off of control room, search the time value corresponding with this outdoor environment temperature afterwards, in the waiting time
After reaching this time value, the outer mainboard of power supply control apparatus control room again obtains electric, obtains outdoor environment temperature and stores.
Step S814: determine the outdoor environment temperature got nearest twice.
Step S815: according to the corresponding relation of outdoor environment temperature Yu time value, determines the outdoor that the last time gets
Time value corresponding to ambient temperature.
Step S816: the relatively the last outdoor environment temperature got and the front outdoor environment temperature once got
Degree.
Step S817: the outdoor environment temperature got when the last time is equal to the front outdoor environment temperature once got
Time, using the time value that determines as Preset Time.
Step S818: the outdoor environment temperature got when the last time is higher than the front outdoor environment temperature once got
Time, using the product of the time value determined and the first regulation coefficient as Preset Time.
Wherein, the first regulation coefficient is more than 1.
Step S819: the outdoor environment temperature got when the last time is less than the front outdoor environment temperature once got
Time, using the product of the time value determined and the second regulation coefficient as Preset Time.
Wherein, the second regulation coefficient is less than 1.
If the last operation obtaining outdoor environment temperature performed is not to perform for the first time, then the most straight
Connect time value corresponding for this outdoor environment temperature as the special time waited, and further according to the variation tendency of temperature
This time value is adjusted.If the outdoor environment temperature that the last time gets is higher than the front outdoor environment once got
Temperature, then explanation external environment condition is the process gradually heated up, and now increases the time interval waited further.If it is the last
The outdoor environment temperature got is less than the front outdoor environment temperature once got, then gradually lower the temperature during explanation external environment condition
