Owing to move in the time of compressor A and B 31a and 31b, shortened the time of indoor temperature (Tr) arrival preset temperature (Ts).Like this, when altered indoor temperature (Tr) is not higher than preset temperature (Ts), close intermediate exhaust mouth 18 by the swing of intermediate blade 18a, and close compressor A and B 31a and 31b (S170～S190) simultaneously.Thereafter, air-conditioner is returned to initial operational mode (double operational mode).
The result who judges as step S340 be an indoor temperature (Tr) when not being higher than preset temperature (Ts)+4 ℃, and control module 120 control compressor operation unit 130 operation compressors B 31b (S400) are to meet the operational mode (double operational mode) of user's selection.
When because the operation of compressor A 31a, indoor temperature (Tr) changes and when reaching preset temperature (Ts), once more close compressor A 31a (S410～S420).
When because the closing of compressor A and B 31a and 31b, indoor temperature (Tr) rises to when being higher than preset temperature (Ts)+1 ℃ once more, need judge once more whether indoor temperature (Tr) is higher than preset temperature (Ts)+4 ℃.When the result who judges be an indoor temperature (Tr) when being higher than preset temperature (Ts)+4 ℃, air-conditioner will move under home mode, promptly move compressor A and B 31a and 31b simultaneously with increase working capacity to 100%; When the result who judges is an indoor temperature (Tr) when not being higher than preset temperature (Ts)+4 ℃, air-conditioner will continue to move under double operational mode, promptly only move working capacity and be 60% compressor A31a.
Though the air-conditioning of describing in the preferred embodiments of the present invention has two compressor A and B 31a and 31b, the invention is not restricted to this, air-conditioning of the present invention can have two or more compressors.
And, though described in a preferred embodiment of the invention under single and double operational mode, when indoor temperature (Tr) exceeds the working capacity that need improve compressor A and B 31a and 31b when difference between the preset temperature (Ts) is higher than the value of an appointment, but the present invention is not limited to this.Also can under single and double operational mode, when indoor temperature (Tr) is lower than the value of an appointment of preset temperature (Ts), reduce the working capacity of compressor A and B 31a and 31b like this.
From the above description can be clear, the invention provides the method for a kind of air-conditioner and this air-conditioner operation, based on the difference between indoor temperature and the preset temperature, control the compressed capability of compressor length by length, when this difference hour, the working capacity that reduces compressor makes power consumption reduce, and when this differed greatly, the working capacity that improves compressor was to shorten the time that indoor temperature reaches preset temperature.
And according to the control method of air-conditioner of the present invention and operation thereof, the working capacity of control compressor and control are discharged the temperature of direction with the broad interior space of control quickly from a plurality of side air, thereby offer comfortable air-conditioning effect of user.
Though embodiments of the present invention are described, but it will be appreciated by those skilled in the art that, under the situation that does not deviate from principle of the present invention and marrow, can change real-time mode of the present invention, scope of the present invention is limited by claims and equivalent thereof.
