When the air conditioner is started, the second control valve 2, the third control valve 3 and the sixth control valve 6 are opened, the first control valve 1, the fourth control valve 4, the fifth control valve 5 and the seventh control valve are opened and closed, the first bypass valve 01 and the second bypass valve 02 are closed, a refrigerant flows out of an exhaust port of the compressor 10, exchanges heat with the outdoor heat exchanger 20 through the four-way reversing valve 50, passes through the sixth control valve 6, is throttled by the throttling device 60, enters the indoor heat exchanger 30 through the third control valve 3, refrigerates the indoor space, and then flows back to a return air port of the compressor through the second control valve 2 and the four-way reversing valve 50 to perform compression circulation. In the whole process, the refrigerant flows through the outdoor heat exchanger 20 and the indoor heat exchanger 30 in sequence for heat exchange, and the fourth control valve 4 is closed, so that the refrigerant cannot flow through the refrigerator 40, and the refrigerator 40 is not in operation.
When the indoor temperature deviation reaches a preset range, controlling the first control valve 1, the second control valve 2, the fourth control valve 4 and the sixth control valve 6 to be fully opened, opening the a/b of the third control valve 3, controlling the fifth control valve 5 and the seventh control valve 7 to be closed, enabling a refrigerant to flow out of an exhaust port of the compressor 10, exchanging heat through the four-way reversing valve 50 and the outdoor heat exchanger 20, throttling the refrigerant through the sixth control valve 6 by the throttling device 60, dividing the throttled refrigerant into two paths, enabling one path of the refrigerant to enter the indoor heat exchanger 30 through the third control valve 3 to refrigerate the indoor space, and enabling the refrigerant to flow back to a return air port of the compressor through the second control valve 2 and the four-way reversing valve 50 to perform compression circulation; the other path of the refrigerant enters a refrigerating area 41 of the refrigerator 40 through a fourth control valve 4 to refrigerate the refrigerator, and then flows back to a return port of the compressor through the first control valve 1 and the four-way reversing valve 50 to perform compression circulation. At this time, although the energy required for cooling the indoor heat exchanger 30 is reduced, since the cooling of the refrigerator is newly turned on, the compressor 10 still needs to be operated at a high frequency in order to provide sufficient heat exchange energy while satisfying the requirements for indoor cooling and refrigerator cooling.
