extracting suspected solar lowest input power of each adjusted power characteristic curve, and forming a characteristic sequence containing M suspected solar lowest input powers;
and comparing all the suspected solar lowest input powers in the characteristic sequence one by one according to the sequence, determining the minimum value of the M suspected solar lowest input powers, and taking the suspected solar lowest input power corresponding to the minimum value as the solar lowest input power.
9. An energy-saving operation control device of an air conditioner, comprising: the device comprises an acquisition judging module (30), a first determining module (40) and a second determining module (50);
the obtaining and judging module (30) is used for responding to a starting signal of an energy-saving mode, obtaining solar input power transmitted to the air conditioner body (20) by the photovoltaic panel group (10), and judging according to the solar input power;
the first determining module (40) is used for determining that the solar minimum input power meets the lowest frequency operation requirement of the air conditioner body (20), and then the photovoltaic panel group (10) supplies power to the air conditioner body (20);
the second determining module (50) is used for determining that the lowest solar input power does not meet the lowest frequency operation requirement of the air conditioner body (20), and then the solar energy and the commercial power supply jointly supply power to the air conditioner body (20).
10. An air conditioner characterized in that, when performing an energy saving control, the energy saving operation control method of the air conditioner according to any one of claims 1 to 8 is employed or the energy saving operation control apparatus of the air conditioner according to claim 9 is included.
