Fig. 1 is the flow chart of the control method of air-conditioner according to embodiments of the present invention.As it is shown in figure 1, the control method of this air-conditioner comprises the following steps:

S1, when air-conditioner enters sleep operating mode, obtains current indoor ambient temperature.

Specifically, when user prepares to sleep, it is possible to enter sleep operating mode by " sleep " on remote controller by key control air-conditioner, when air-conditioner enters sleep operating mode, air-conditioner obtains current indoor ambient temperature.

S2, it is judged that the temperature range residing for current indoor ambient temperature, wherein, is divided into multiple temperature range, an operation phase of each temperature range correspondence air-conditioner, the operational factor of corresponding one group of air-conditioner of each operation phase by indoor environment temperature.

Specifically, can according in user's sleep procedure to the demand curve of cold and night outdoor environment temperature change curve, the night of air-conditioner is run and is divided into multiple operation phase, such as can being divided into four operation phase, there is the operational factor of the air-conditioner of each independent entry condition, exit criteria and correspondence each operation phase.In multiple operation phase, the operation time that high frequency takes the electricity stage is short, and the operation time in low frequency energy-saving stage is longer.

S3, temperature range residing for current indoor ambient temperature controls air-conditioner and enters the corresponding operation phase, and obtains the operational factor of air-conditioner corresponding to the corresponding operation phase, and according to the operational factor obtained, air-conditioner is controlled.

It is to say, in an embodiment of the present invention, it is possible to rapidly room temperature is fallen first with compressor high frequency, adopt low frequency energy-saving to run afterwards, detect indoor environment temperature T after some hours, and it is judged.When detection indoor environment temperature T more high, next stage can select the running frequency of higher compressor to run, and if detection indoor environment temperature T relatively low, then low frequency can be adopted to run down always.So regulate more fine, not only act as energy-conservation purpose, and noise can be reduced, be greatly improved the comfort level of user.

nullAccording to one embodiment of present invention，When current indoor ambient temperature is be more than or equal to the first preset temperature，Control air-conditioner and entered for the first operation phase，Wherein，In the first operation phase，Control compressor to run with the first predeterminated frequency，And control room inner blower runs with the first preset rotation speed，And control outdoor fan runs with the second preset rotation speed，And，Air-conditioner operation time of the first operation phase more than the first Preset Time and current indoor ambient temperature less than the second preset temperature time，Control air-conditioner and switched to for the second operation phase from the first operation phase，Wherein，In the second operation phase，Control compressor to run with the second predeterminated frequency，And control room inner blower runs with the 3rd preset rotation speed，And control outdoor fan runs with the 4th preset rotation speed，Second predeterminated frequency is less than the first predeterminated frequency，3rd preset rotation speed is less than the first preset rotation speed，4th preset rotation speed is less than the second preset rotation speed，Second preset temperature is less than the first preset temperature.Wherein, the first to the second preset temperature, the first to the second predeterminated frequency, first to fourth preset rotation speed and the first Preset Time can be demarcated according to practical situation.

Specifically, when air-conditioner enters sleep operating mode, obtain current indoor ambient temperature, and judge which operation phase air-conditioner enters according to current indoor ambient temperature T.As in Figure 2-4, if current indoor ambient temperature T >=the first preset temperature such as 27 DEG C obtained, then control air-conditioner and be directly entered for the first operation phase, now the running frequency F1 of compressor can be 60Hz, the running speed N1 of indoor fan can be 1250rad/min, and the running speed M1 of outdoor fan can be 900rad/min.When air-conditioner is when the operation time S1 > 0.5h of the first operation phase and current indoor ambient temperature T < the second preset temperature such as 25 DEG C, the first operation phase terminated, and air-conditioner is automatically into the second operation phase.When air-conditioner entered for the second operation phase, the running frequency F2 of compressor can be 12Hz, and the running speed N2 of indoor fan can be 500rad/min, and the running speed M2 of outdoor fan can be 400rad/min.

Specifically, as the air-conditioner operation time S2=1.5h in the second operation phase, detection current indoor ambient temperature T, if T < the 3rd preset temperature such as 26 DEG C, then control air-conditioner keep the operational factor of the second operation phase and continue to run with, until air-conditioner shutdown or operational mode are switched；If the 3rd preset temperature is 26 DEG C≤T < the 4th preset temperature such as 28 DEG C such as, then illustrate that low frequency refrigeration can not maintain stablizing of indoor temperature, need raising frequency to increase the refrigerating capacity of air-conditioner, so now air-conditioner was switched to for the 3rd operation phase by the second operation phase.When air-conditioner entered for three operation phase, as in Figure 2-4, the running frequency F3 of compressor can be 20Hz, and the running speed N3 of indoor fan can be 700rad/min, and the running speed M3 of outdoor fan can be 600rad/min；If T > the 4th preset temperature such as 28 DEG C, then illustrate that outdoor environment temperature is also in higher temperature levels, it is necessary to more colds make room lower the temperature, therefore, control air-conditioner and returned for the first operation phase, to continue high frequency refrigerating operaton.

nullAccording to one embodiment of present invention，When current indoor ambient temperature is less than the first preset temperature and be more than or equal to five preset temperatures，Control air-conditioner and entered for the 3rd operation phase，Wherein，In the 3rd operation phase，Control compressor to run with the 3rd predeterminated frequency，And control room inner blower runs with the 5th preset rotation speed，And control outdoor fan runs with the 6th preset rotation speed，3rd predeterminated frequency is more than the second predeterminated frequency and less than the first predeterminated frequency，5th preset rotation speed is more than the 3rd preset rotation speed and less than the first preset rotation speed，6th preset rotation speed is more than the 4th preset rotation speed and less than the second preset rotation speed，5th preset temperature is less than the second preset temperature，And，When air-conditioner reaches the 3rd Preset Time and current indoor ambient temperature less than six preset temperatures in the operation time of the 3rd operation phase，Control air-conditioner and switched to for the 4th operation phase from the 3rd operation phase，Wherein，In the 4th operation phase，Control compressor to run with the 4th predeterminated frequency，And control room inner blower runs with the 7th preset rotation speed，And control outdoor fan runs with the 8th preset rotation speed，4th predeterminated frequency is less than the 3rd predeterminated frequency，7th preset rotation speed is less than the 5th preset rotation speed，8th preset rotation speed is less than the 6th preset rotation speed，6th preset temperature is more than the first preset temperature；When air-conditioner reaches the 3rd Preset Time and current indoor ambient temperature be more than or equal to six preset temperatures in the operation time of the 3rd operation phase, control air-conditioner and be back to for the first operation phase from the 3rd operation phase.

That is, air-conditioner enters the condition of the 3rd operation phase: after user selects sleep operating mode, the current indoor ambient temperature T detected meets the 5th preset temperature such as 24 DEG C≤T < the first preset temperature such as 27 DEG C, or, air-conditioner is at the operation time S2=1.5h of the second operation phase, and the current indoor ambient temperature T detected meets the 3rd preset temperature such as 26 DEG C≤T < the 4th preset temperature such as 28 DEG C, control air-conditioner and entered for the 3rd operation phase.As in Figure 2-4, when air-conditioner entered for three operation phase, the running frequency F3 of compressor can be 20Hz, and the running speed N3 of indoor fan can be 700rad/min, and the running speed M3 of outdoor fan can be 600rad/min.When air-conditioner is when the operation time S3=2h of the 3rd operation phase and current indoor ambient temperature T < the 6th preset temperature such as 28 DEG C, air-conditioner switched to for the 4th operation phase from the 3rd operation phase.When air-conditioner entered for four operation phase, the running frequency F4 of compressor can be 12Hz, and the running speed N4 of indoor fan can be 500rad/min, and the running speed M4 of outdoor fan can be 400rad/min.When air-conditioner is when the operation time S3=2h of the 3rd operation phase and current indoor ambient temperature T >=the 6th preset temperature such as 28 DEG C, air-conditioner was back to for the first operation phase from the 3rd operation phase.
