The speed that lotus reduces.
Fig. 3 is the schematic control flow chart of indoor fan according to an embodiment of the invention.Specifically, referring to Fig. 3,
When halt instruction is the remote-control closedown signal sent by remote controler, control method of the invention further include:
After compressor is out of service, control air conditioner indoor fan continue to run preset duration after, obtain indoor ring
The delivery temperature of border temperature and compressor；
It needs to continue to run after determining indoor fan self-operating preset duration according to indoor environment temperature and delivery temperature
The second duration；And
It is out of service after control indoor fan the second duration of operation.
That is, when halt instruction is the remote-control closedown signal sent by remote controler, it is indoor after compressor shutdown
Blower can automatically continue to run a period of time (preset duration), and then according to indoor environment temperature and compressor at this time
Delivery temperature determine the second duration for needing to be further continued for operation after self-operating preset duration.As it can be seen that the extension of indoor fan
Runing time (i.e. the second duration) be according to after compressor shutdown delivery temperature and indoor environment temperature jointly determine because
The delivery temperature of compressor can accurately react the real system load of air conditioner at this time, and indoor environment temperature can be accurate
The current indoor integrated environment of ground reaction, can make prolonging for indoor fan under the premise of not influencing indoor integrated environment as a result,
The real system load of long running time and air conditioner matches.
Further, under same indoor environment temperature, the second duration and being positively correlated property of delivery temperature.That is,
Under same indoor environment temperature, delivery temperature is higher, and the value of the second duration is bigger；Delivery temperature is lower, the value of the second duration
It is smaller.When delivery temperature is higher, illustrate that the system loading of air conditioner is larger, at this point, the extension duration of runs of indoor fan gets over
Long, the pressure release of system loading is just more abundant.When delivery temperature is lower, illustrate that the system loading of air conditioner is smaller, at this point, indoor
Blower only needs the shorter extension duration of runs i.e. and can guarantee that system loading pressure release is abundant.
Under same delivery temperature, the second duration and being positively correlated property of indoor environment temperature；That is, in same row
At a temperature of gas, indoor environment temperature is higher, and the value of the second duration is bigger；Indoor environment temperature is lower, and the value of the second duration is smaller.
In some embodiments, after the delivery temperature for obtaining compressor, control method of the invention may also include that
Second speed of service of the indoor fan in the second duration is determined according to delivery temperature；
Indoor fan is controlled according to out of service after second speed of service the second duration of operation；
Second speed of service and being positively correlated property of delivery temperature, and second speed of service is less than or equal to the default of indoor fan
Highest wind velocity.
That is, can also pass through the speed of service of the control indoor fan in its extension duration of runs (i.e. the second duration)
Promote air conditioner more effectively pressure release.Particularly, when delivery temperature is higher, indoor fan extends the operation in the duration of runs at it
Speed is bigger (but the default highest wind velocity for being no more than indoor fan)；When delivery temperature is lower, indoor fan is when extending operating
The interior speed of service is smaller.When delivery temperature is higher, illustrate that the system loading of air conditioner is larger, at this point, indoor fan with
Higher speed of service operation, can increase heat exchange, to ensure that system loading pressure release is more abundant.When delivery temperature is lower, say
The system loading of bright air conditioner is smaller, at this point, indoor fan need to only be run within the extension duration of runs with the lesser speed of service
It can guarantee that system loading pressure release is abundant.
Specifically, after compressor is out of service, indoor fan is according to wind speed of the compressor before out of service after reforwarding
Row preset duration.The section locating for the delivery temperature is (T1, T2) when, second speed of service is the wind before compressor is out of service
Speed.The section locating for the delivery temperature is [T2, ∞) when, second speed of service is the default highest wind velocity of indoor fan.It is apparent that
T1Less than T2.Specifically, the section locating for the delivery temperature is (T1, T2) when, the value of delivery temperature be not also it is very high, it is indoor at this time
Blower only need the speed of service according to compressor before out of service run the second duration can fully pressure release, avoid compared with
Avoiding under the premise of more energy consumptions leads to air conditioner because system loading is excessive or temperature is excessively high when compressor is again turned on
The phenomenon that cancel closedown or protection are shut down.The section locating for the delivery temperature is [T2, ∞) when, the value of delivery temperature is relatively
Height, at this point, indoor fan, which needs to preset the second duration of highest wind velocity operation according to it, can ensure system fully pressure release.
Referring to Fig. 3, when halt instruction is protection stopping signal, control method of the invention further include:
When air conditioner indoor fan from compressor it is out of service after continued to run preset duration after, obtain compressor
Delivery temperature；

Indoor fan is controlled according to third speed of service continuous service.
That is, after compressor shutdown, indoor fan is continuous service when halt instruction is protection stopping signal
, only the speed of section operation may be different in different times.Blower is out of service subsequent from compressor indoors
In time after reforwarding row preset duration, the speed of service (i.e. the third speed of service) of indoor fan is according to exhaust at this time
Temperature determines.Because the delivery temperature of compressor can accurately react the real system load of air conditioner at this time, as a result,
The real system load of the speed of service and air conditioner of the indoor fan after having run preset duration may make to match.
In some embodiments, after compressor is out of service, wind of the indoor fan according to compressor before out of service
Speed continues to run preset duration.The section locating for the delivery temperature is (T1, T2) when, the third speed of service is to press than indoor fan
The wind speed of the high grade of wind speed before contracting machine is out of service.The section locating for the delivery temperature is [T2, ∞) when, third operation
Speed is the default highest wind velocity of indoor fan.It is apparent that T1Less than T2.Specifically, the section locating for the delivery temperature is (T1,
T2) when, the value of delivery temperature is not also very high, but compressor is shut down because of protection after all, the operation of indoor fan at this time
Speed want a little higher than compressor out of service before the speed of service, just can fully pressure release, avoiding more energy consumption
Under the premise of avoid when compressor is again turned on cause because system loading is excessive or temperature is excessively high air conditioner cancel closedown or
The phenomenon that protection is shut down.The section locating for the delivery temperature is [T2, ∞) when, the value of delivery temperature is relatively high, at this point, indoor wind
Machine, which needs to preset highest wind velocity operation third duration according to it, can ensure system fully pressure release.
In some embodiments, when the halt instruction that air conditioner receives is to protect stopping signal, and work as the row of compressor
Temperature degree is less than T1When, the speed of service of indoor fan become again compressor it is out of service before speed, to avoid energy dissipation.
The present invention also provides a kind of air conditioner, which carries out according to control method described in any of the above-described embodiment
Operation.As a result, after receiving halt instruction and promoting compressor shutdown, outdoor fan will not stop immediately, but need to extend
Runing time reduces its system loading, reduces when compressor is again turned on because of system loading to carry out pressure release to air conditioner
Excessively high the phenomenon that causing air conditioner cancel closedown or protection the to be shut down generation of excessive or temperature, improves the experience effect of user
Fruit.The extension runing time (i.e. the first duration) of outdoor fan is determining according to the delivery temperature after compressor shutdown, because
The delivery temperature of compressor can accurately react the real system load of air conditioner at this time, may make outdoor fan as a result,
The real system load for extending the duration of runs and air conditioner matches, both will not because of outdoor fan the extension duration of runs it is too short
And cannot veritably reduce system loading, and will not because of outdoor fan the extension duration of runs it is too long and increase the energy of air conditioner
